RFID technology is widely used, and the unmanned weighing industry has also been well interpreted. The intelligent weighing management system has become an important technology for information management in various weighing industries such as coal mines, garbage dumps, petroleum industry, and non-ferrous metal mines. RFID technology provides an intelligent and information-based management solution for these industries with its non replicability, strong anti-interference ability, fast identification, and intelligent discrimination, realizing a new type of weighing intelligent management mode that is efficient, accurate, fast, and anti cheating. RFID technology makes unmanned weighing management intelligent.

By using an RFID radio frequency card, the card number, vehicle license plate number, owner's name, entry time, and entry location related information of the electronic tag are saved in the weighing host database. When the vehicle is weighed through the car scale channel, The RFID radio frequency reader reads the electronic tag on the vehicle to determine whether it is a legitimate vehicle. The intelligent barrier gate is opened by sending instructions through the weighing host, and the infrared and signal lights are activated. The barrier gate is immediately closed, and the reader antenna carries information from the electronic tag of the vehicle to the weighing host. The weighing host collects data from the weighing instrument of the car scale to record the tare weight, and the infrared detects whether the vehicle is parked in place. The camera captures the image, and the weighing host automatically records the relevant information and saves it to the database. Then, the command is issued to open the barrier gate. The traffic command system instructs to lower the scale, and the voice command system and LED electronic display screen prompt the driver to drive slowly. After the vehicle detector senses the vehicle passing, the weighing host sends an instruction to lower the barrier gate.

specific implementation

The unmanned weighing system achieves automation of weighing and weighing through the following means:

1

The combination of RFID radio frequency devices and software enables automatic identification of vehicles and avoids the mixing of different types of materials. By developing corresponding software modules to connect RFID radio frequency devices to unmanned systems, automatic identification of vehicles at various locations such as weighing scales and warehouses can be achieved, effectively controlling the dynamics of vehicles in the factory area and ensuring that vehicles do not mix up when loading and unloading materials due to entering the wrong warehouse.

2

The infrared collimator ensures that the vehicle is fully weighed, avoiding errors in weighing data caused by multiple vehicles being weighed simultaneously. Install infrared cameras around the weighing scale. When the vehicle is not fully weighed or when two or more vehicles are weighed simultaneously, the infrared camera signal will be blocked, the system will automatically sound an alarm, and the weighing measurement will be stopped.

3

Various financial and statistical interfaces are abundant, effectively integrating enterprise resources, and achieving one-stop pre-sales, after-sales, and financial management. The unmanned weighing system includes various statistical and financial modules, which can effectively integrate with the enterprise's financial ERP, management ERP and other systems, enabling the effective integration of weighing measurement with enterprise finance and management. All weighing data can be queried, counted, calculated and stored separately.

　　4

The combination of SMS group sending device, camera and software enables customer leaders to understand various weighing processes from the office. The unmanned system can instantly send alarm information and other information required by customers during the weighing and weighing process to the mobile phones of enterprise leaders through SMS, making it easier for leaders to understand the weighing situation in a timely manner. Leaders can also view real-time weighing images through the video system.

Based on RFID technology, automatic measurement can greatly shorten the operation time of each operation link, improve the unloading capacity of the measurement system, reduce labor intensity, save labor costs, avoid human operation loopholes, effectively prevent cheating, greatly improve weighing efficiency, and truly achieve unmanned intelligent weighing.
