Technology is transforming the way we work. Businesses have been utilizing various digital tools in promoting the new smart working model. One of the tools that is widely used in the corporate world is the interactive whiteboards technology is advancing, more and more interactive whiteboards of different brands and models are introduced to the market. Choosing the most suitable interactive whiteboard for your business can be challenging, especially when you have a unique requirement to meet.

However, in our opinion, buyers need to check and compare some of the most important features of interactive whiteboards before making any purchase. No matter how powerful or attractive a interactive whiteboard is, it would not help your business if it cannot even provide these important features.

In this article, we will look at the top 5most important features that an interactive whiteboard should have.

1.Whiteboard Feature

2.Document Viewer

3.Video Conferencing

4.Web Browsing

5.File Saving & Transfer

 

Whiteboard Feature

As an alternative to a whiteboard, it does not make sense if an interactive whiteboard is not equipped with a basic whiteboard feature. Users must be allowed to write or erase directly on the HD smart board panel. Besides, the whiteboard feature should also allow the user to change pen colour or the stroke thickness easily.You can always get one or two smart pens when you purchase a whiteboard. Pen writing is the core feature of an interactive whiteboard. A great whiteboard product can provide a smooth and intuitive pen writing experience. In short, a good interactive whiteboard should allow the user to at least do whatever he can with a whiteboard.

 

Document Viewer

A great interactive smartboard must have the ability to support various digital file formats such as Word documents, PPT, PDF, images, and videos. Broad compatibility is important. Users want to display any content that they prefer fast and easily, so they can focus on more important tasks such as discussion and decision making.

Video Conferencing

Remote meeting or video conference is the trend nowadays. The recent global pandemic also leads to the boom of video conferencing. Video conferencing plays an important role in both teaching and meeting purposes. Hence, consumers are constantly looking for a tool or a solution that can help them to communicate without travelling.

A few years ago, video conferencing was not a feature that whiteboard manufacturers would pay attention to. However, things are different today. Most interactive whiteboards in the market today are equipped with built-in front cameras and video conferencing applications. Some can even support popular applications such as Zoom and Google Meet. Besides, manufacturers have also started to put more effort into improving the built-in speakers and the microphones. Video conferencing is an important feature that could never be missed.

Web Browsing

The greatest benefit of using a whiteboard is its ability to allow an active discussion among participants. An active discussion is a discussion where every participant is free to share his or her ideas without limitations. Ideas can come in many forms such as sketches, images, texts, and videos.Unlike traditional displays such as whiteboards and projector screens, an interactive whiteboard is not only a display. It is also a tool that helps users to access a resource library with all sorts of information. Thanks to the built-in internet browser, users of an interactive smartboard can always look for information or resources online during a discussion.When an idea or information is accessible, a discussion or a classroom session can run effectively without any delay.

File Saving & Transfer

As a highly collaborative digital display, the abilities of an interactive whiteboard in file saving and transferring are extremely important. If an interactive whiteboard cannot import or export a file easily, it is no different than a conventional whiteboard.Users can always upload files to the interactive whiteboard from their smartphones or devices. After annotating or making notes onto any displayed document, the annotated document can be saved and transferred to participants’ devices via the wireless connection or scanning the QR code. Besides, most interactive whiteboards are equipped with USB ports. Users can plug in USB drives anytime to transfer files.

 

Conclusion

Different organizations or consumers have different criteria when selecting the most appropriate interactive whiteboard. However, no matter what your standard is or what your application is, if the interactive whiteboard is not equipped with the functions mentioned above, you should not buy a interactive whiteboard. Without these features, it will never help you run your application smoothly. A car without wheels is never a car.

There are four important components to make up a UHF RFID system, the host computer, the reader, the antenna and the electronic label.

 

The host computer sends a command to the reader, the reader turns on the RF module to send UHF signals under the control of the host computer commands, a magnetic field is created around the RFID tag by means of an antenna. When the magnetic field is strong enough, the chip circuit inside of the tag is activated, then the tag carries information is loaded into the electromagnetic wave and returned to the reader. The reader receives and converts the data information, then processed by the upper computer, complete the process of acquiring electronic tag information.

 

Host computer

The UHF RFID reader requires the host computer to issue control instructions which can start the reader to send RF signals, the reader receives the signal returned by the tag also needs to be processed and stored by the host computer that can achieve the normal work of the entire UHF RFID system.

 

The upper computer can be independent of the reader, can also be integrated into the reader, the market common Raspberry Pi, Android reader is the upper computer integrated into the reader.

 

Hopeland’s UHF android fixed reader, shine 340 can accurate and fast reading, high sensitivity.

 

The reader

The UHF reader, or RF module, is a key component of the entire RFID system. Firstly the RF module determines the frequency band in which the whole system will operate. Secondly, the read-write's sending power and receiving sensitivity directly affect the whole system's maximum recognition distance.

Shine 340’s sensitivity has -85dbm, it’s far more sensitive than commercially available.

 

The antenna

Antenna is a passive device for the interconversion of electromagnetic waves and current signals.

 

Most common UHF RFID readers on the market are single-antenna or quad-antenna configurations, but these two readers are only suitable for inventorying a small range of electronic tags. Inventory larger range of electronic label, if uses many sets of reader to complete the task, not only will bring the high cost, but also need to solve many sets of reader simultaneously work the signal mutual interference problem.

 

Multi-antenna structured UHF RFID reader, not only can inventory of electronic labels in a wide range, but also no problem of mutual interference of the signal of each antenna port of the reader. Because each antenna port is time division multiplexed.

 

In practice, the number of antennas and the placement of the antennas should ensure that the radiation range of the antennas can cover all RFID tags. This ensures that all tags can be identified by at least one antenna in the warehouse management process, enabling high speed and leak-free identification in warehouse management.

 

Hopeland’s 4/8/12/24 antenna ports fixed reader can meet the needs of different applications.

 

The tags

The electronic tag is a data carrier consisting of a dipole antenna, a resonant capacitor and a micro IC chip. The sensitivity of the tag has a pivotal influence on the reading and writing distance of the RFID system.

 

The Interface circuits

The two main components are generally the baseband control circuit program configuration interface circuit and the upper computer communication interface circuit. The communication interface between the reader and the host computer is usually RS232, RS485, USB and RJ45 etc.

 

The work indication function circuit

Real-time knowledge of the entire reader's working situation through the status of the indicators.

Includes reader power-on indication, power-on indication, RF module power indication and each antenna port operating status indication

Compared with paper barcodes, the RFID operating environment is inseparable from the three major parts of readers, antennas, and RFID tags. Combining the actual situation of clothing retail stores and the characteristics of RFID technology, four main links are used in store warehousing: fast receiving, fast finding, inventory counting, and inventory overview.

 

When receiving goods quickly, staff use the RFID scanner to scan the delivery note number, enter the detailed list of delivery notes, after scanning, click "Confirm Receipt" to complete the receipt.

 

When quickly looking for goods, the staff used the scanner camera to scan the barcode of a piece of clothing, and select the color and size. They can also find other colors and sizes of the clothing item.

The number of clothing shelves and warehouses is displayed on the interface. The staff uses the handheld scanner to inspect the clothing. When the pat reader approaches the garment, there will be a voice prompt, and the staff can find the designated clothing in the area.

 

During inventory counting, the staff creates a new inventory receipt and enters the inventory details page, and use the camera reader to take inventory of the store. After the inventory is completed, the inventory details page will display the corresponding inventory profit and loss status, click "confirm upload" to complete the inventory. The "Inventory at a Glance" page displays the number of all apparel displays and the number of stores in the store in real time for staff to view.

 

Store sales management module

It is mainly used in four aspects of store sales management: intelligent display, intelligent fitting, reporting, and intelligent cashier. The display monitoring interface displays the clothing status of the current monitoring display area in real time. When the clothing is removed, put back or placed incorrectly, there will be corresponding prompts, And record the corresponding error display record, pick and place record and replenishment information into the system.

 

When the stock is out of stock for a certain period of time and there is no timely replenishment, the system will automatically generate a replenishment reminder, and the staff will replenish the goods in time according to the replenishment reminder to ensure the display quantity. The sales statistics report is used to count all the garments in transit/inventory, display quantity, sales quantity, fitting times and other data.

 

When purchasing, the customer places several pieces of clothing in the scanning area of the cashier at the same time. The system quickly scans the clothing information and total price in batches. Click "confirm payment" and swipe the rfid card on the reader. The system automatically deducts the amount on the card to complete the cashier.


If you need to return the goods, the customer will place the clothing to be returned in the scanning area of the cashier at the same time. The system quickly scans the clothing information and total price in batches, click "Confirm Return", and the system automatically returns the total price of the clothing to the membership card to complete the return.

Why was intelligent access control born?

The fierce competition in business has made business information security the focus of attention, The pursuit of security has led to higher and higher requirements for the security system of modern buildings. The intelligent access control system manages important passages in buildings. The access control system can control the entry and exit of personnel, Ensure the free entry and exit of authorized personnel and restrict entry of unauthorized personnel, Intelligent access control management not only facilitates internal management, but also enhances internal security, thereby providing users with a safe working environment.The access control system based on RFID technology, as an advanced management technology, has been widely used in scientific research, industry, museums, hotels, shopping malls, medical surveillance, banks, prisons, etc. in some countries.

 

 

Access Control System (ACS) refers to a system that manages and controls entrances and exits. It not only includes narrowly defined doors for people to enter and exit, but also includes vehicle access control, logistics access control, etc.The management technology of the access control system has already surpassed the simple doorway and key management, but has gradually developed into a complete set of access management technology.


 

Form a complete access control system

The basic components of the access control system are Identity recognition, sensing and alarm, processing and control, electric lock and execution, wiring and communication, management and setting and so on. All parties coordinate and cooperate to realize the access control system's access management restriction, real-time monitoring, abnormal alarm and other functions to ensure safety and reliability.

 

The entry and exit certificate is the "ID card" for entering and exiting the system. Only when the system recognizes the entry and exit certificate will it be allowed to pass through the door. Depending on the system, cards, passwords, and biological characteristics of the human body may all be used as vouchers for the access control system.

 

The recognizer is mainly responsible for reading access credentials and passing data information to the controller. The controller is the core of the entire access control system, responsible for the transmission, processing, control and storage of the entire system data information, and is equivalent to the computer's CPU. The recognizer generally uses the RS232 or RS485 interface to communicate with the controller. Locks are the executive parts of the entire system, mainly electronic locks, magnetic locks and electric bolt locks, etc. The background management software is the operating basis for all hardware coordination and is responsible for the background monitoring and management of the access control system. Managers can use the access control system to set and identify the authority of personnel at any time, directly control the illegal entry of personnel, and record the personnel and time of each controlled area in real time. When problems occur, they can consult historical records and analyze personnel entering and exiting.

 

Classification of RFID Smart Access Control

The main access control systems on the market can be divided into two categories according to the control method, independent access control system and networked access control system.

(1) Independent access control adopts non-networked control mode,no host computer is needed, but offline control is performed directly through the embedded microcontroller, the independent access control system has no statistics, query and other functions. The social demand for independent access control systems is relatively large. Free-standing access control system price

It is cheap, easy to install and maintain, and is suitable for places with a small number of people.

 

(2)The networked access control system requires an upper computer to interact with the computer in the control center. The management software required by the access control system is installed on the host computer. Through the software to control the access authority of the electronic tag, implement operations such as issuing and canceling the card, and can query the access control records. Due to more functions, the cost of a networked system is higher than that of an independent system. Such an access control system is often used in situations where there are many users and detailed records of personnel entering and exiting, such as the entry and exit management of the community and the company's attendance management.

 

Hopeland’s new super slim design-i3 RFID Portal Access Control RFID Tracking Gate Reader can optional independent access control or network access control, supports EPC C1G2 (ISO18000-6C) protocol, integrated high-gain antenna groups, the R2000-based reader and speed control module, with high-speed tag reading literacy and good control of the area, It provides a standard RS232 or RJ45 interface for easy connection software platform.

The high-frequency inverter power supply converts the original low-voltage direct current into low-voltage high-frequency alternating current through DC/DC high-frequency conversion technology, then boosts the voltage through a transformer, and then rectifies the high-frequency rectified and filtered current into high-voltage direct current with an average value of more than 300V v.  Because the high-frequency magnetic core material of the high-frequency sine wave inverter is small in volume and light in weight, the power density of the circuit can be greatly improved, the no-load loss of the sine wave inverter is reduced to be very low, and meanwhile, the conversion efficiency of the sine wave inverter is improved.  The peak conversion efficiency of small and medium-sized high-frequency sine wave inverters can reach more than 90%

 

Power frequency sine wave inverter:

Sine Wave Inverter, Solar Inverter, MPPT Controller, Inverter Power Frequency Inverter Power Supply is used by converting DC direct current into low-frequency AC alternating current and boosting it to 220V mains supply through a transformer.  The structure of power frequency sine wave inverter is relatively simple, and various protection functions can be realized in low voltage working environment.  In the circuit using the power frequency sine wave inverter, the power supply is stable in operation, strong in anti-interference performance and good in overload capacity, so it is relatively reliable and can suppress higher harmonic components.  However, its size is relatively large, its price is relatively high, and its relative power is also very low.  According to the current manufacturing process, the rated load efficiency of the sine wave inverter is not more than 90%, so under the condition of no load, its loss is large and its efficiency is low.

 

The above is a summary of the differences between high frequency and power frequency sine wave inverters. It can be seen that at present, high frequency sine wave inverters has more market value.

The main function of MPPT controller is to detect the DC voltage and output current of the main circuit, calculate the output power of the solar array, and track the maximum power point. The disturbance resistor R is connected in series with the MOSFET. Under the condition that the output voltage is basically stable, the average current through the resistor is changed by changing the duty ratio of the MOSFET, thus causing current disturbance.  At the same time, the output current and voltage of the photovoltaic cell will also change accordingly. The change of the output power and voltage of the photovoltaic cell before and after the disturbance is measured to determine the disturbance direction of the next cycle. When the disturbance direction is correct, the output power of the solar photovoltaic panel will increase, and the next cycle will continue to disturb in the same direction. Otherwise, it will disturb in the opposite direction. In this way, the disturbance and observation will be repeated to make the solar photovoltaic panel output reach the maximum power point.

With the progress of society and the improvement of productivity, the demand for energy is increasing with the development of human beings. The demand for electric power is expected to increase every year. At present, China's power source mainly relies on fire and thermal power generation. Clean solar power generation has gradually prevailed in recent years. The products related to solar power generation system are also numerous and varied in quality.  Take inverter and controller products as an example. Many friends who have just entered the industry do not know much about it, which leads to ambiguity in product selection. 


For example, a customer asked whether it is necessary to purchase a controller when purchasing off-grid inverter. AnHui JNGE INVERTER manufacturer is popular here:

 

Firstly, the inverter function is simple and clear, that is, to convert 12V/24V/48V/72V direct current (storage battery, storage battery, direct current power supply) into 110V/ 220V/380V alternating current commonly used in household and the controller is used when charging the battery with photovoltaic modules, which can maintain a stable charging process, avoid the battery from being damaged by overshoot and reverse current damage to the photovoltaic modules caused by reverse current flowing out of the battery. Therefore, the full name of the controller is also called solar charging and discharging controller, which is divided into MPPT type solar control and PWM type solar controller.  Everyone should pay attention to the specific use requirements and the configuration of photovoltaic modules when selecting, and select the appropriate inverter or controller.

One, Complete models. Brand models of solar high-power inverters are very complete, especially some big brands will introduce new products every year, in order to enable their brands to occupy the market advantage, and the practicability of high-quality equipment will certainly be stronger.  Moreover, the models of major brands are very complete. We need inverters of any style, which can be purchased directly without worrying about shortage.


Second, the quality is guaranteed. To be able to set up a big brand, naturally, has also passed the corresponding national audit, and many businesses are also strictly controlled, only in this way can our brand go further and have greater influence.  The quality of branded solar high-power inverters is strictly controlled.

Diaphragm pump, also known as a Membrane pump, is mainly composed of motor, transmission components, flexible diaphragm, and check valves. It utilizes a flexible diaphragm that reciprocates back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump. When the volume of a chamber of pump is increased, the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume, the fluid previously drawn in is forced out. Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle.

 

AJK produces complete lines of mini diaphragm pumps for more than 15 years, like AJK-B1201, AJK-B2701, AJK-B3601, etc. Please feel free to contact us if any requirements on the mini diaphragm pumps, thanks

UHF RFID electronic tags usually refer to electronic tags that conform to the ISO18000-6C & EPC C1G2 protocol. Of course, there are also electronic tags of the ISO18000-6B protocol, but the ISO18000-6B protocol is gradually marginalized.


First, what needs to be considered is the storage structure of UHF electronic tags?


1. What is the model of the chip?


2. What is the memory map of the chip in the chip's specification?
Generally, the electronic label of the 6C protocol is divided into a TID area, an EPC area, a user area, and a reserved area. The TID is the serial number of the solidified chip and cannot be changed. The EPC area is the most frequently used and written area. Some tags have a user area, and some tags, except for the user area, are usually reserved for storing access passwords.

What kind of data do we need to store in UHF RFID electronic tags? Does the data need to be encrypted?


A typical case is the coding method used in the RFID clothing industry.

96 bit EPC, can store 24 HEX in total, how to allocate these 24 HEX is more important, the following figure clearly lists the storage type of a certain garment,


1- 14 for the product UPC
15-19 digits for clothing information such as style, color, size

20--24 digits are the serial number


Access password and inactivation killing password, add according to your own needs, but you need to pay attention to whether the chip itself can perform password operations

Finally, prepare the UHF RFID reader for batch writing.

Indian company Agra Nagar Nigam has decided to simplify solid waste management by installing RFID tags, which are installed in 99,450 houses in 51 communities and handing over 350 RFID handheld readers to cleaners.

Homeowners must put dry garbage and wet garbage in different bins and pay a Rs 65 management fee each month.


When the cleaner collects garbage from the house and scans the RFID tag installed in the house, it will automatically signal to the command and control center of the Agra Smart City Office. After collecting garbage, the homeowner will receive a text message from the mobile phone.


If cleaners do not collect garbage at home, homeowners can also complain through mobile apps.


Homeowners must keep the RFID tags intact. If there is a problem with the label, the homeowner will pay a fine of Rs 100 for this.


The collected garbage will be sent to six collection centers located at different locations in the city. The dry waste is then sent to the processing plant and the wet waste is sent to the composting plant.

Bar codes and RFID tags are both item information identification technologies, and their essence is to give a special number to an item, through which you can get information about the item.


The bar code is numbered by knowing the change of the image by optical means.


The RFID tag can be considered as the electronic version of the barcode, and its working principle is the radio principle. The number information in the RFID tag chip is obtained through the process of electromagnetic wave carrier and modulation.

RFID tag category:
Low-frequency electronic tags:
Its operating frequency range is 30kHz ~ 300kHz.

Typical operating frequencies are: 125KHz, 133KHz (There are other frequencies close to it, such as TI uses 134.2KHz).


High and medium frequency electronic tags:

The working frequency of mid-to-high frequency electronic tags is generally 3MHz ~ 30MHz. Typical operating frequency is 13.56MHz.


UHF and microwave tags:
Ultra-high frequency electronic tag, its typical working frequency is: 433.92MHz, 862 (902) ~ 928MHz;
Microwave range: above 3GHz

Ultra-high frequency (UHF) ranges from 300MHz to 3GHz, and microwave ranges above 3GHz. RFID systems using UHF and microwave are called UHF RFID systems. Typical operating frequencies are 433MHz, 860 ~ 960MHz, 2.45GHz, 5.8GHz, and the frequency wavelength is around 30cm.


UHF tags can be active or passive, and communicate with the reader through electromagnetic coupling. The communication distance is generally greater than 1m, typically 4-6m, and the maximum can exceed 10m.


Radio waves in the UHF band cannot pass through many materials, especially suspended particulate matter such as water, dust, and fog.


UHF readers have very high data transfer rates and can read a large number of electronic tags in a short period of time.


The reader is generally equipped with a directional antenna, and only tags within the directional wave speed range of the reader antenna can be read and written.


The antenna inside the tag is long and label-like. The antenna has two designs, linear and circular polarization, to meet the needs of different applications.


The data storage capacity of UHF tags is generally limited to 2048bit.


From a technical and application perspective, tags are not suitable as a carrier of large amounts of data. Their main function is to identify items and complete the non-contact identification process. Typical data capacity indicators are 1024bit, 128bit, 64bit, etc.


Typical applications include supply chain management, production line automation, air parcel management, container management, railway parcel management, and logistics management systems.

Breast pump suction level is measured in mmHg – milimetres of mercury – which is the standard unit of measuring vacuum pressure. When you’re buying a breast vacuum pump, you might see mmHg in the product listing. This number, generally in the range of 220 to 350, is the maximum suction level. Hospital grade pumps generally have maximum suction levels in the 300 range while personal grade pumps are generally in the 200 range. This doesn’t necessarily make a pump better or worse – it’s just symptomatic of hospital grade pumps having bigger, stronger motors since they are designed for more rigorous use. AJK mini vacuum pumps have been well used in the breast pump products for a long time. The different size and parameters of mini vacuum pumps are used for different suction level of breast pump.

RFID Electronic Tags are packaged in many forms, are not limited by standard shapes and sizes, and their composition is also very different, and even requires special design according to various requirements. The Transponder has been used in sizes ranging from ¢6mm to 76x45mm, small or even micron-sized chips, including antennas with a size of 0.4×0.4mm; storage capacity from 64-200bit read-only ID numbers. The small-capacity type is a large-capacity type (for example, EEPROM 32Kbit) that can store tens of thousands of bits of data; the package material is from self-adhesive to open-molded plastic.

The material, composition, and the like of the various package forms of the electronic tag are different.

Card type (PVC, paper, other) laminated, both melted and sealed.

The melt pressure is made by heating the INLAY sheet of the center layer and the upper and lower pieces of PVC material. The PVC material is fused with INLAY and then die-cut into the size specified in ISO7816.

When the chip adopts a Transponder, the chip is raised above the antenna plane (the antenna thickness is 0.01 to 0.03 mm), and another lamination method, that is, sealing, can be used. At this time, the substrate is usually PET or paper, and the thickness of the chip is usually 0.20 to 0.38 mm. When the card is packaged, only the PVC is sealed at the periphery of the antenna, and the chip is not fused, and the chip is not pressed, so that the chip can be prevented from being crushed. 

Gluing type, using paper or other materials to make the Transponder upper and lower materials glue together by cold glue, and then die-cut into cards of various sizes.

(1) Label-type paste type, the finished product can be made into the label form of manual or labeling machine, which is the most mainstream product in the application, that is, the electronic label attached to the back of the trademark is directly attached to the object to be marked. Such as aeronautical baggage tags, pallets, etc. Hanging type, which corresponds to clothing and articles using hanging products, is characterized by compact size and can be recycled. (2) Shaped metal surface type, most electronic labels will be affected by metal and will not work properly. These tags are specially treated and can be placed on metal and can be read and written. It is used for the surface of various metal parts such as pressure vessels, boilers and fire-fighting equipment. The wristband type can be used once (eg medical) or reused (eg playground). The animal and plant use type can be an injection type glass tube, a hanging ear tag, a buckle type foot ring, and the like.

With its breakthrough technical features and wide applicability, electronic label technology has been increasingly recognized by the market. With the further improvement of the chip manufacturing process, packaging process, and the maturity of packaging equipment and materials, electronic tags will be more suitable for our needs. At the same time, we have left us with a series of new topics that we need to improve and improve.

RFID is a non-contact automatic identification technology. This technology was born during the Second World War and is mainly used to identify aircraft.


The simplest RFID systems include tags, readers and antennas. Additional hardware and software support is required in the real world.

About RFID Reader

The reader is divided into two types: handheld reader and fixed reader. It consists of a transceiver, an antenna, a receiver, and a control module.

 

Fixed readers generally have multiple antenna ports. Users can have multiple antennas to implement one reader to read and write tags from multiple places at the same time, or configure multiple antennas with different angles for the same tag. To ensure read and write efficiency.

 

 Fixed RFID Reader

 

About RFID Tag

The most common is the passive RF system. When the reader encounters the RFID tag, it emits electromagnetic waves and forms an electromagnetic field around it. The tag obtains the microchip circuit in the energy-activated tag from the electromagnetic field. The chip converts the electromagnetic wave and sends it to the reader. The reader puts It is converted into related data. The control calculator can process this data for administrative control.

1: The core function of the solar controller is to charge and discharge the battery in the solar power system. One is to prevent the battery from overcharging, causing the battery to be overfilled and damaged or exploding. The second is to prevent the battery from being over-discharged, so that the battery can not be charged, resulting in failure to be damaged or invalid.

 

2: Because the environment used is different from the region, the operating temperature of the solar controller is also different. In places with large temperature difference, the solar controller should also have the function of temperature compensation.

 

3: Other additional functions such as: light control switch, time control switch, etc. These solar controllers should be optional.

 

A solar charge controller is mainly responsible for regulating the energy which flows between solar modules and batteries used in storing up energy generated from solar panels. And controls the power output of the solar cell module and the battery to the load according to the power demand of the load, which is the core control part of the entire photovoltaic power supply system.

 

When a PV power system is working optimally, there is the likelihood of the battery getting overcharged. This is because the solar panels are built for the purpose of generating higher levels of voltage which if not controlled could lead to damage of the solar power system.

As one of the key technologies of security and Internet of Things, RFID is currently rich in related products and solutions, and the market application is gradually deepening. The application fields are expanding and expanding, especially in intelligent transportation, smart parking, smart access control, radio frequency security, personnel and Areas such as item positioning and track management have gradually gained very mature applications.

 

Taking jewelry management as an example, the jewelry industry has problems in the exclusive counters of specialty stores. The products that the jewelry industry sells every day are high-value jewellery, which is very important for the daily inventory of goods.

However, the current work of jewellery inventory is basically done by manual manual operation, and the jewellery products have the small size and large number of actual situations. A large number of products are counted by a small number of sales personnel, which results in a huge actual situation of inventory work time.

After adopting the RFID scheme, the target object can be automatically identified by the RFID handheld terminal, and the identification work no longer requires manual intervention. RFID jewelry management is to attach RFID tags to precious jewelry products. Combined with the jewelry counting equipment(fixed RFID reader) installed on the counter, it is used to monitor, control and track the labeling of jewelry accessories, enabling fast inventory and real-time management functions.

In addition to convenience, RFID products have high stability, no mechanical wear and long service life, so the maintenance cost is relatively low. This is an important reason for domestic users to accept and innovate the new RFID technology.

When using the existing RFID Demo software, the length of the read operation cannot exceed 255 words, which is 510 bytes. This is also the upper limit of the amount of data read by Gen2. Reading too much data at a time will also cause the performance of the reading to be unstable. In fact, reading 128 words at a time is not stable. This is related to the performance of the specific label. When actually doing the project, it should be sufficient. After testing, choose an appropriate value as the number of single reads and writes.

There are a lot of UHF RFID tags in the user area, such as 1K bytes, how to read the large-capacity data area? There are two ways to read 1K bytes of data as an example:

Call the readWait SYNC API 4 times, reading 128 words each time;

ReadWait offset=0, size=128 words;

ReadWait offset=128, size=128 words;

ReadWait offset=256, size=128 words;

ReadWait offset=384, size=128 words;

Call the “Actions.TagAccess.Operation Sequence.performSequence” ASYNC API multiple times (recommended this way - good performance)

If 128 words is unstable, you can read 64 words, 32 words or less each time, and the number of calls increases accordingly. The read and write performance of different UHF RFID reader is different. According to the actual test, the amount of read and write data of a single sequence is adjusted; the number of calls is increased accordingly.

From the perspective of technological development, high-frequency technology is relatively mature than UHF technology. Through continuous improvement and improvement, a learning curve model for high-frequency tag production, data protocol sharing, and the basis for constructing RFID applications has also been established.

Both high frequency and ultra high frequency RFID systems rely heavily on the communication environment between the RFID reader and the tag. UHF uses the principle of electromagnetic emission and is therefore more susceptible to electromagnetic interference. At the same time, the metal will reflect the signal, and the water will absorb the signal, all of which will interfere with the normal function of the tag.

The International Organization for Standardization/International Electrotechnical Commission established the ISO/IEC, 15693 standard in 1999 to regulate the implementation of high frequency radio frequency identification technology. The standards for UHF are not so uniform, and the frequencies used in different countries are not the same. The UHF designated by the EU is 865~868MHz, the United States is 902~928MHz, India is 865~867MHz, Australia is 920~926MHz, Japan is 952~954MHz.

The European Telecommunications Standards Institute (ETSI) EN300-220 specification has two main provisions that are less favorable for UHF. One is about the power limitation, which stipulates that the effective radiated power is 500 mW; the second is about the bandwidth limitation, and as a result, the reader cannot be frequency hopped.

RFID tags have received a lot of praise from users in practical applications. Although the price is relatively high, UHF RFID technology has obvious unique advantages in automatic identification and security of products, and the production efficiency and management of enterprises will be has seen an increase.

With the improvement of people's living standards, the number of liquefied petroleum gas cylinders has also increased dramatically. Liquefied petroleum gas has many problems, such as wide use, large quantity, large liquidity, harsh use environment and lagging regulatory measures, which cause huge safety hazards.

Under this background, it is urgent to strengthen the government safety supervision of liquefied petroleum gas cylinders, implement the policy of cylinder construction, fixed-point filling, and regular inspection, and establish a networked dynamic gas cylinder safety management system.

RFID technology has played a key role in this management system. Through RFID technology, the identity of the gas cylinder can be quickly and accurately identified, the production efficiency can be improved, and the gas cylinder to be inspected can be prevented from flowing into the production process, resulting in quality hazards.

Specific process:

1. First, establish a computer resume file database of gas cylinders.

2. Use the RFID handheld reader to read the electronic label of the gas cylinder, and the on-site operation data of the process of sending and receiving the gas cylinder, pre-charge inspection, filling and filling, re-inspection, and periodic inspection are collected and registered.

3. Alarms and prompts for abnormal and bad cylinders.

4. At the gas station, register the gas cylinders entering and leaving the gas supply station to prevent other gas cylinders from entering the enterprise through the gas station channel.

RFID technology can effectively integrate the daily management activities of medical assets with the medical asset management system, so as to achieve the real-time synchronization of physical information and system information, and quickly find various medical assets in an emergency.

 

 

Each medical asset is attached with an electronic tag with a unique ID number. When the item with the electronic tag enters the identification area of the reader, the information that the electronic tag keeps issuing will be received by the long distance RFID reader. The writer passes the information to the computer, and the computer system performs corresponding format conversion, filtering, and subsequent statistical processing to determine whether the item should be stored here and other related information.

The outer packaging of the drug is affixed with a barcode, and the drug and barcode information is registered in the background. When the nurse distributes the medicine to the patient, the scanner scans the barcode of the medicine, and then checks the patient's wrist label information, and distributes the medicine to the patient after confirming that the photos, names, and medical names in the hand are consistent. At the same time, the handheld terminal wirelessly transmits the distributed information to the background management center for information storage.

The temperature sensor can be used to continuously monitor the internal temperature for 24 hours to prevent unnecessary loss due to temperature changes. The temperature tag transmits the temperature change signal to the reader, and the reader transmits the signal to the background operating system. When the temperature exceeds the acceptable range, an audible and visual alarm is issued, and the detailed alarm freezer or thermostat location, storage items, etc. are clearly indicated. information.

In 2002, Metro announced the "Future Store" program, which announced the adoption of RFID technology throughout its supply chain. The program has attracted more than 50 partner companies to jointly develop and test applications for IoT RFID technology, covering all aspects of the retail supply chain, including inventory, transportation, logistics, warehousing, and even the retail in-store customer buying experience.

Metro has built a comprehensive tracking system for RFID pallets and deployed multiple RFID applications. Pallet tracking is the basis of the distribution center RFID system. More than 100 Metro's suppliers use RFID tags in their warehouses, logistics, distribution containers and pallets.

A fixed RFID reader device is installed on the warehouse door. When the pallet passes through the warehouse door, the data on the container label can be automatically identified, collected, and transmitted to the enterprise system through automatic finishing; the system will provide this information. Check with the electronic data of the delivery notice, the pallets that meet the system order will be approved by Metro, and the inventory system of the supply chain will be updated as soon as the goods are put into storage. This process does not require manual intervention, which greatly reduces labor costs.

From ordering, date of manufacture, storage time, transportation, receiving, warehousing, sales, settlement, and reordering, the accuracy of delivery and labor cost reduction are ensured. UHF RFID readers have high accuracy and can scan accurately and quickly. Containers and goods; RFID electronic tags have a large amount of information and are highly resistant to interference. They can be used repeatedly and have high security and confidentiality. They can be reused and are more environmentally friendly while saving costs.

The RFID chip is used to establish an identity card for the construction site personnel. By setting a long range RFID card reader in the floor, the RFID chip information can be read out instantly, and the location and personal information of the construction site personnel can be known. At the same time, the information is uploaded to the network cloud through the computer host, and the information is viewed through the network platform or the mobile APP to realize remote monitoring. Provide a convenient and reliable solution in the real-name system and security management of labor services.

A base station is installed on each door of the entrance and exit. When the tag is worn with the helmet through the entrance and exit, it can be recognized by the fixed RFID reader, with nearly 100% accuracy and extremely fast response speed.

 

When the staff loses the construction hat, the system can know which layer the hat is on, and then the floor search can be performed through the handheld terminal. When the handheld PDA is closer to the hat, the stronger the signal strength displayed on the APP, the target search.

The method can theoretically realize the functions of real-time positioning, historical track playback, information query, map monitoring, personnel distribution viewing, personnel real-time positioning, and historical information query.

The user can locate the personnel through the corresponding functions, add, delete, modify and query the basic information, play back the historical track of the personnel, print out the reports, and add and modify the users who use the system. , delete and query, statistics on the distribution of people. Users can manage each site and each area on the computer and mobile phone through simple operation.
