1 Overview
With the rapid development of China’s economy, the requirements for energy and polluting companies are becoming higher and higher. Production efficiency must be high and human labor intensity must be paid more attention to. In some industries, simple manual recording operations can no longer meet the needs of users for weight management. Fast, accurate, high-efficiency weighing, networking of multiple truck scales to achieve data sharing, effective management of weighing data, unattended weighing on-site, and anti-cheating weighing are becoming more and more important for enterprises.
In response to the actual needs of the society, companies with various capabilities have begun to study unattended weighing management systems. What it provides to users is no longer just a simple weighing equipment, but a complete set of weighing management solutions. Through the implementation of the supporting vehicle automatic identification system, the efficiency of weighing measurement and management will be improved and improved, and the measurement results will be more accurate, true and effective. At the same time, the resource sharing of weighing data will be realized, and the financial and transportation settlement of customers will be realized. , Provide relevant measurement data for the control of incoming and outgoing materials.
The system consists of a digital electronic truck scale and an automatic vehicle identification management system. When a vehicle equipped with an electronic tag passes through the weighing location, the system can detect whether the vehicle belongs to the system vehicle and make a judgment whether it can be weighed. If it is detected as a vehicle of the system, the vehicle can be automatically weighed without stopping ( That is, automatically command the vehicle to go up and down, automatically recognize the vehicle number, and automatically record and save the 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, garbage treatment plants, cement plants and other industries.
2. Working principle
Install an electronic tag that has established a one-to-one correspondence with the vehicle number in the appropriate position of each vehicle. When the vehicle is effectively inquiring the RF beam through the antenna, the electronic license plate receives the directional inquiry RF signal sent by the antenna, and stores its own The electronic information is modulated and reflected back to the antenna, so that the card reader can automatically read the electronic license plate information, and according to the read information and weighing conditions, the vehicle is directed to scale up and down in order to realize the automatic identification and weighing of the vehicle and the management of the weighing data.
