The intelligent service of the hotel is a goal pursued by the high-class hotel. It can provide guests with special services to make guests have a special feeling and leave a deep impression on the guests; at the same time, it can also establish the unique brand of the hotel. The RFID-based smart hotel system has enhanced the level of intelligent services and management for high-grade hotels, enriched the service content, and laid a solid foundation for guests to provide other special services.
1. VIP guidance system
For the hotel's VIP guests, the hotel will offer RFID VIP card in advance. When the VIP guest enters the hotel or enters the car park by car, the system will send information about the VIP guests to the store through the RFID reader device at the entrance. Automatically and promptly notify the corresponding hotel management personnel and service personnel to remind them of the appropriate services so that the guests feel more respect.
2. Floor navigation system
When guests stay at the hotel and check in, they will bring the room card to the passenger elevator. The long range RFID reader will automatically identify and send the relevant information to the backstage via the Internet to obtain the relevant information of the guests. The passenger elevator will reach the floor where the guest arrives and get out of the elevator. The integrated LCD screen in the hallway will show the guest's room arrow directions, and the system will send a signal to the room intelligent control system.
3. Banquet/Conference Management System
By installing RFID readers inside and outside the entrance of the ballroom and multi-function hall, and using service personnel's portable RFID reader, automatically recognize and enter the conference room. After the RFID tag, the corresponding personnel, time, and location of the RFID tag are obtained and recorded automatically. Including the number of people who should arrive at the meeting, and the number of people who are currently available.
UHF RFID reader receivers also require transmitters to send unmodulated carriers when operating. Receivers include tag reflection signals, antenna noise, environmental reflections, direct transmitter coupling, and the receiver's own noise. Now if we want to stably read a distance of 10 meters, and let RFID readers achieve 100% recognition rate and be able to adapt to changes in the weather and the environment, the effect of reading is better than that of common products. What should I do?
Practice: Processing Baseband Digital Signals
Oversampling and filtering. Oversampling can reduce the power of quantization noise in the effective bandwidth and improve the signal-to-noise ratio, which is equivalent to increasing the resolution of the ADC. The data obtained by oversampling can be extracted by the CIC filter, so that the data rate can be returned to the normal level and then cascaded. FIR filters are band-pass filtered to further reduce noise power and improve signal-to-noise ratio.
DC offset correction. Simply through the capacitive AC coupling method can filter out the DC part of the signal to reduce the DC offset interference. This method is the simplest structure, the lowest cost, and thus the most widely used.
Data decoding. The baseband data decoding method is divided into zero-crossing detection and coherent detection. Zero-crossing detection works by setting a threshold. Each data sample in the data buffer is compared with the median value. Because this method is simple and easy to implement, even a comparator can be used to implement the decision, which is widely used in Ethernet RFID reader products.
The advantage of RFID technology is more reflected in the group reading, and the core of this advantage lies in the anti-collision algorithm. You can choose a good product at the time of purchase. A good process design and some necessary fault-tolerance mechanisms will affect The read/write performance of an RFID product also involves RFID's 100% recognition rate in practical applications.
The pharmaceutical RFID supply chain information platform built using RFID technology can realize real-time tracking and supervision of pharmaceutical production, circulation, distribution and retail links. Because RFID tags have the technical characteristics of large storage capacity, fast transmission speed, non-counterfeiting, and concurrent identification, they can be reliably real-time-tagged within a tag by supporting the supply chain platform database and attaching RFID tags to individual pharmaceutical products. Record drug-related supply chain information to enable real-time supervision of the pharmaceutical supply chain.
As a pharmaceutical manufacturer, pharmaceutical companies are responsible for attaching RFID tags to pharmaceutical packaging. Distribution-related units (including drug wholesalers, pharmaceutical retailers, and medical institutions) have a dedicated RFID reader writer. Pharmaceutical companies conduct product authentication and circulation information writing operations in the product outbound and outbound links.
The drug administration department can use portable RFID reader identifiable read-write devices to carry out on-site inspections and identification of drug-related units' inventory and drug sales.
When a consumer purchases a drug in a hospital or pharmacy, he or she can authenticate the drug through an identifiable device or a self-service authentication handheld terminal in the hospital or pharmacy.
Attach electronic tags to each bottle of medicine to record data such as location, product category, date, etc. According to the unique code of each product, you can keep abreast of the state of the goods, the quality of medicine, etc., so that you can manage your inventory and you can immediately understand Items that need replenishment are convenient for out-of-stock management.
With the development of RFID technology, many companies are now focusing on RFID technology solutions. Thanks to the RFID technology's ability to identify multiple tags at the same time in a non-contact, non-visual environment, a full range of tens of items with electronic tag-attached apparel can be read by the UHF RFID reader once and for all. , greatly improved the efficiency of logistics.
The benefits of RFID technology in clothing logistics are reflected in logistics management efficiency, logistics cost, and delivery control. The application of RFID technology realizes the standardization of garment logistics operations, shortens the operation process and operating time, and reduces labor costs, thereby reducing operating costs, increasing the throughput of logistics links, increasing the transparency of supply chain management, and improving the efficiency of logistics management. At the same time, the use of RFID solution can minimize the delivery error rate. The delivery error mainly refers to the shortage of the original box and the packaging box error.
When garments are processed from the factory for storage, the staff put the goods on a forklift and send it to the back-end warehouse. If conditions permit, a reader and RFID antenna can be installed on each forklift to identify RFID tag data. When the forklift takes the goods to the warehouse, it is read by the reader at the warehouse door and sends the tag information to the warehouse. Management system to record the details of goods receipt.
The manufacturer's label is affixed to the clothing item to be sent and verified before delivery, after which an early shipping notice is issued to the retailer. After the packaged garment arrives at the distribution center, it will be placed on the conveyor belt. During the transfer process, these labeled packaged garments will be read by the fixed RFID reader. The data after reading will be transmitted to the system. The software will confirm the ID information. Inaccurate or lost system will issue a warning reminding staff to check the garments in the box.
