1、 Introduction to unmanned intelligent weighing system for weighing scales:

The unmanned intelligent weighing system solution for weighing scales is equipped with two sets of infrared reflectors, one IC card reader, one voice horn, two signal lights, and two cameras on each scale. Before the vehicle is loaded onto the scale, the 1 # signal light is green, and after the vehicle is loaded onto the scale, the 2 # signal light is red. When the weight is greater than the minimum value set by the system, the signal light is red. After the vehicle stops steadily, the driver gets off the vehicle and swipes his card to weigh it. The system automatically detects the infrared reflectors. If the vehicle is not fully loaded onto the scale, the system prompts the driver to drive to the middle of the scale, otherwise weighing is not allowed. If everything is normal, the computer management system reads the vehicle number, tare weight, and other related information (such as the shipping unit) based on the IC card., receiving unit, material source, driver name, etc.) The camera captures two sets of images (front and rear) and saves them together with weight information. The system stores the weighing results in the database, the printer automatically prints out the documents, the barrier gate automatically lifts, and the voice prompts the vehicle to lower the scale. All processes of the system are completed, and the signal light turns green. The enterprise management department can also query real-time weighing data and related on-site weighing images of a certain day, time period, or even a certain vehicle through the local area network.
The system mainly consists of electronic car scales, computers, printers, video surveillance, wireless RF card reading systems, traffic lights, barrier gates, and anti remote cheating devices. The system can also be upgraded with hardware and software on the basis of the electronic truck scale currently used by the user. The system adopts a standard WINDOWS window interface, with Chinese prompts, simple and intuitive user operation, convenient query and statistical reporting, and truly achieves on-demand settlement of measurement work, making weighing data accurate and reliable, and improving work efficiency and economic benefits. The system has two humanized operation modes: manual and unmanned. In an unmanned state, automatic printing of weighing and scale sheets can be completed without manual intervention, making it a powerful assistant for modern metrology. The RFID intelligent weighing management system automatically identifies and accurately measures the vehicle number, while preventing various cheating methods by external personnel from causing economic losses to the enterprise. In addition, the implementation of the system can greatly reduce the labor intensity of staff and the error rate of manual weighing, upgrading from traditional manual operation mode to manual control mode. Improve the transparency of management processes and assist in enterprise informatization. Enterprises have a large number of transportation vehicles entering and exiting every day, requiring procedures such as parking, registration, and weighing. The data is manually entered into the computer by operators, which is not only time-consuming but also has a high error rate. In addition, there is cheating behavior by external personnel, causing significant economic losses to the enterprise. The intelligent weighing and control system combines RFID radio frequency identification technology, electronic vehicle scale technology, communication technology, automatic control technology, database technology, and computer network technology to automatically record the license plate number, weight information, time information, etc. with electronic tags entering and leaving, and write them into the host database, which can effectively prevent human errors, overloading and blockage.
