The rapid development of China's economy is increasingly demanding energy companies and polluting enterprises. Production efficiency is high, and people's labor intensity must be paid attention to. In some industries, manual simple recording operations cannot meet the needs of users' symmetric management. Fast, accurate, high-efficiency weighing, multiple truck scale networking to achieve data sharing, efficient management of weighing data, unattended on-site weighing, and anti-cheating weighing are becoming more and more important to enterprises.
In response to the actual needs of the society, each capable enterprise began to study the unattended weighing management system. It provided the user with more than just a simple weighing device, but a complete weighing management solution. Through the implementation of the automatic vehicle identification system, the weighing and management efficiency will be improved and improved. The measurement results will be more accurate, real and effective. At the same time, the resource sharing of weighing data will be realized, and the customer's financial and transportation settlement will be realized. Relevant measurement data is provided for the control of materials into the factory.
The system consists of a digital electronic truck scale and an automatic vehicle identification management system. When the vehicle with the electronic tag passes through the weighing place, the system can detect whether the vehicle belongs to the system vehicle and make a judgment to determine whether it can be weighed. If it is detected that the vehicle is the system, the vehicle can be automatically stopped without stopping ( That is to automatically command the vehicle to scale up and down, automatically identify the car number, automatic recording and storage of weighing data, which can greatly improve the user's work efficiency and work quality, and improve the management level of the enterprise. This system has been widely used in thermal power plants, waste treatment plants, cement plants and other industries.
2. Working principleInstall an electronic tag with a one-to-one correspondence with the car number at the appropriate position of each car. When the vehicle effectively queries the RF beam through the antenna, the electronic license plate receives the directional RF signal sent by the antenna and stores it. The electronic information is modulated and reflected back to the antenna, so that the card reader automatically reads the electronic license plate information, and commands the vehicle to scale up and down according to the read information and the weighing condition, thereby realizing the automatic identification weighing and weighing data management of the vehicle.
