Truck scale weighing system based on RFID technology application


RFID technology can identify specific targets and read and write related data through radio signals without identifying the system and specific target 125k~134.2K), high frequency (13.56Mhz), ultra high frequency, microwave (2.4-2.5Ghz) and other RF technologies. .


The basic working principle of RFID technology: after the tag enters the magnetic field, it receives the RF signal from the reader, and sends the product information (passive tag, passive tag or passive tag) stored in the chip by the energy obtained by the induced current, or by The tag actively sends a signal of a certain frequency (Active Tag, Active Tag or Active Tag), and the reader reads the information and decodes it, and sends it to the central information system for data processing.


A complete RFID system consists of a reader (Reader) and an electronic tag (TAG) and application software system. The working principle is that the Reader transmits a specific frequency of radio wave energy to the Tag for driving. The Tag circuit sends the internal data, and the Reader receives the interpretation data in order, and sends it to the application for corresponding processing.


At present, the RFIDs used by our unattended truck scale weighing system are passive RFID products, and the working frequency is 900-960MHZ. The truck scale weighing system can be unattended with the contactless induction card swiping technology. When the car is parked on the weighing platform, the weighing software automatically collects the vehicle information through the RFID device. After weighing the software to judge the weighing data is stable, the photo is captured simultaneously. To save gross or tare, you can use a camera to capture the photo of the driver when swiping, then print the receipt, the vehicle is released, and then start the next car. When a car comes to the tare for the second time, the software automatically calls up the vehicle information. After the software determines that the vehicle is stable, it starts to capture the tare photo, saves the weight, and then combines the data with the first gross weight. Record, calculate the net weight, and then print the document. In this way, the gross weight, tare weight, net weight data of the car, the photos when the gross weight and the tare weight are saved, and the card number of the driver, the card number and the car number are correspondingly stored in the computer, and the car number and the card number on the photo are found to be inconsistent. If the driver's photo is inconsistent, the driver is suspected of cheating. Therefore, the general driver does not dare to change the vehicle to ensure that the weighing weight and the weighing weight are the same vehicle. RFID unattended truck scale weighing system is widely used in power plants, coal mines, non-ferrous metal mines, garbage dumps, cargo terminals and other units.
