Card recognition is divided into two categories: the first one is a magnetic card, but the magnetic card is low in security, easy to wear and requires frequent magnetization; the second is an RFID card, which is cheap, easy to use, highly secure and can use a database. It is well managed, its cost performance is extremely high, and it has a good promotion prospect.
The working principle of the whole access control system is: one person and one card, and establish corresponding personal information in the database management system according to the serial number of the card. When the door is to be opened, the card is brushed on the lower computer, and the RFID gate reader transmits the serial number to the upper computer server. The server queries the corresponding personal information in the database according to the serial number and transmits it to the lower computer.
At the same time, the lower computer reads the data of the fixed sector block of the card (reading the card), compares the read data with the data sent by the upper computer, and opens the door exactly the same, otherwise the LCD displays an error and does not open the door.
The overall software design of the access control system includes the software design of the lower computer reader and the software design of the database management system of the upper computer. The access control system of the access control system is mainly to realize the reading of the card and the communication with the host computer management system, and is implemented by C language programming in the Keil4 environment.

The RFID pet dog vaccine management system fundamentally solves the problem of pet loss, abandonment and supervision. The pet electronic chip with a global unique identification number (UID) will be used as a pet's electronic ID card, and it will be stored in the pet chip for the rest of its life. The basic information of the pet is transmitted to the computer application software through the Ethernet RFID reader, thereby realizing automatic identification and analysis of the pet identity, the owner, and the information of reproduction, health and epidemic prevention throughout the life, and realizing the information of the pet management.
The chip can record basic information about pets, such as name, gender, date of birth, etc. Information such as the type and time of the vaccine received by the pet will be stored in the pet chip or database and will be stored in the pet chip or database. Only authorized personnel can pass the management software or the Internet.
If a pet is lost, as long as it has an RFID pet chip, it can quickly get the information of the pet owner, effectively preventing the increase of stray dogs.
Due to the openness of the pet chip user data area, as long as the RFID reader device conforms to the chip protocol, the pet's open information can be read, so that the pet supervision department, the epidemic prevention department, the pet hospital, etc. can easily share the pet information. The management of pets brings great convenience.
Photovoltaic (PV) Panel make electricity from sunlight, and are marvelously simple, effective, and durable. They sit in the sun and, with no moving parts, can run your appliances, charge your batteries, or make energy for the utility grid.
A solar panel array is the energy collector—the solar “generator” and does so via the photovoltaic effect. Discovered in 1839 by French physicist Alexandre-Edmund Becquerel, the photovoltaic effect describes the way in which solar cells create electricity from the energy residing in photons of sunlight. When sunlight hits a solar cell, the cell absorbs some of the photons and the photons’ energy is transferred to an electron in the semiconductor material. With the energy from the photon, the electron can escape its usual position in the semiconductor atom to become part of the current in an electrical circuit.
Most solar cells fall into one of two basic categories: crystalline silicon or thin-film. Crystalline silicon modules can be fashioned from either monocrystalline and polycrystalline.
To use the energy from the array, you may also need other components, such as inverters, charge controllers and batteries, which make up a solar-electric system. The components required are dependent on the system type designed. System types include:
Off-Grid Solar Systems : Although they are most common in remote locations without utility service, off-grid solar-electric systems can work anywhere. These systems operate independently from the grid to provide all of a household’s electricity. These systems require a battery bank to store the solar electricity for use during nighttime or cloudy weather, a charge controller to protect the battery bank from overcharge, an inverter to convert the DC PV array power to AC for use with AC household appliances, and all the required disconnects, monitoring, and associated electrical safety gear.
Grid-Tied Solar Systems : A grid-tied solar system is dependent upon your municipality’s electrical grid. The DC electricity generated by the photovoltaic (PV) panels is sent through a grid-tied inverter, which converts it to AC power that’s compatible with the grid.

At present, the pharmaceutical industry is currently facing the problem of the proliferation of counterfeit and inferior drugs. Some lawless elements are driven by interests to create counterfeit drugs, which threaten people's lives when they take them. With the rapid development of RFID technology, the medical industry in many cities has begun to apply RFID technology. Many hospitals have begun to use RFID handheld reader for ward inspections, and most importantly, RFID technology and handheld terminal products are It has also played a huge role in drug anti-counterfeiting, tracking and supply chain management.
Using RFID technology, when the drug is shipped from the factory, the RFID tag is attached to the drug package, which becomes an inseparable part of the drug. The RFID tag carries all the information. The principle of RFID used for anti-counterfeiting in commodity anti-counterfeiting is to identify the product (The ID), ie the security code (which is encrypted by hardware or software algorithms) is traced and managed through the system management platform, from the supply chain process that the drug subsequently undergoes, and finally to the patient through the retailer or hospital.
Each Ethernet RFID reader can be connected to the server via GPRS or network, and can effectively record and monitor in production, warehousing, logistics and final sales. The RFID tag is the identity card of the drug, and the product identification number (ID), that is, the security code (encrypted by software or hardware algorithm) is written in the RFID chip. This ID is unique in production and storage. In the warehousing and logistics links, including the final sale, although the number of times to collect information is large, the remote RFID reader can be used for non-contact remote identification, so that data can be collected efficiently. Reduce the complexity of manual statistics and queries. Through RFID technology, we can prevent counterfeiting and sales, and improve the handling capacity of accidents. The application of RFID and handheld terminals in drug management supervision still has a large market space.
RFID radio frequency identification technology uses radio frequency for non-contact two-way communication to exchange data for identification purposes. Compared with the traditional magnetic card, IC card or barcode recognition method, RFID has the characteristics of long-distance and non-contact identification, and has strong adaptability to the environment. Through reasonable design, it can work in various harsh environments and has excellent recognition effect. RFID identification work does not require manual intervention, and is suitable for realizing automatic data collection of the system. At the same time, it can recognize high-speed moving objects and recognize multiple electronic tags at the same time, and the operation is quick and convenient.
