Traditional supermarkets provide us with convenience, but it is not difficult to find out, such as the supermarket price tag replacement is not timely or error, the supermarket goods are frequently stolen, the variety of perishable goods can not be monitored and replaced in time, etc. With the maturity of the Internet of Things technology, these problems will be well resolved.
1. Intelligent price tag system
The price tag in the smart supermarket will be replaced with an LED display, and an RFID tag will be attached to each item, and an UHF RFID antenna and a microcomputer processor will be installed on the shelf. When the tally is placed on the shelf, the multiple RFID reader detects the item and contacts the price control system to return the latest price to the on-board microcomputer processor, which is then quickly displayed on the LED display.
2. Inventory control system
When a consumer attaches an RFID tag-equipped product to a shopping cart with an RFID reader device, the system uploads the information to the Internet of Things control system, and the system immediately analyzes the sales speed and sales status of the product, and contacts the season. A series of dynamic factors, such as festivals and stocks, have developed a scientific supply plan and strive to “zero inventory” of commodities.
3. Smart shopping cart
Install a microcomputer processor with an electronic antenna on the shopping cart. When the RFID-changing product leaves the shelf and is placed in the shopping cart, the product has been recorded by the shopping cart. When you finish shopping, just take out the product. The bank card is lightly brushed at the location of the supermarket, and the settlement is completed, eliminating the need for the cashier to scan each handheld terminal.

The intelligent bucket management system is based on RFID technology and consists of modules such as antennas, card readers, tags, and application systems.
The principle is as follows: the card reader sends a modulated signal of a certain frequency containing information through the antenna; when the tag enters the working area of the RFID tag reader, the antenna generates an induced current through coupling, thereby providing a corresponding tag for the tag. At this time, the tag determines whether to respond according to the information sent by the UHF RFID reader, whether to send data; when the card reader receives the signal sent by the tag, after demodulation and decoding, the tag is internally The data is identified and sent to the application.

Power plants, coal yards, garbage dumps and other units will have a large number of materials transport vehicles entering and leaving every day. It is necessary to carry out procedures such as parking, registration, weighing, etc. The operator manually records the data into the computer, which is time consuming and has a large error rate. It is also easy to breed human fraud and cause a lot of economic losses to the company. The RFID weighing tag is placed on the car, and the relevant data is read by the UHF RFID reader to correspond to the vehicle, which provides great convenience for the staff.
The system includes long range RFID readers, antennas, tag cards, electronic truck scales, main engines, signal lights (red, green), automatic gates, ground sense coils, infrared instruments and supporting management software.
When the green signal light is on, the weighing vehicle enters the lane, and after the vehicle enters the lane, the red signal light is on, prohibiting the next vehicle from entering the lane. The vehicle passes through the induction coil to generate a sensing signal. After the Ethernet RFID reader reads the card, the card information is uploaded to the host database, and the vehicle information is called out.
System advantages
1. The identification accuracy of the car number can reach 99.99%, which is suitable for various harsh environments such as wind, snow, rain and fog.
2. The data in the label is highly confidential, and the electronic label (electronic license plate) cannot be forged or copied, which fundamentally eliminates the phenomenon of copying, forgery and cheating;
3. The vehicle electronic tag uses passive technology, the service life is long, no maintenance;
4. Automatic acquisition speed is fast, can achieve fast weighing, improve the efficiency of weighing, eliminating the phenomenon of queuing too much;
