The network version of weighing monitoring management system is adopted, and the software and instrument weight data are displayed synchronously; Weight unit (t? Or? Kg), the weight is automatically converted according to the instrument data. The advanced video surveillance technology (DVR) and weighing management software (W-MIS) are perfectly combined to realize the management purpose of the whole process of video surveillance weighing. During the weighing process, the system automatically videos and captures pictures; Any client (pound house and office) can see the continuous (dynamic) video picture of the weighing site; After the weighing is completed, any client can query and play back the video process and snapshot photos of any truck weighing according to the assigned authority. At present, our company has installed three software client interfaces. The network cables of the three clients are provided and installed by Lian Heng Electronics Co., Ltd. ..
A pair of stainless steel infrared reflection fences are installed at both ends of the truck scale, which requires firm installation and high infrared reflection sensitivity, and can correctly judge whether there is a vehicle loading (unloading), which direction there is a vehicle loading (unloading), and whether the vehicle is full when parking. Ensure the reliability of weighing data and play a certain role in preventing cheating. In the case that the infrared fire does not sense the complete weighing of the vehicle, the weighing system does not work and there is a prompt on the computer screen. When the photoelectric switch is blocked, the data reading function is prohibited.
When one side of the infrared beam senses that a car is weighing, the three cameras located in front, back and middle of the weighing platform will start to record automatically, requiring the cameras to be firmly installed, with clear images and license plates. When the infrared crosstalk induction vehicle has been weighed and the operator operates the weighing, the weigher will automatically capture the picture and save it at the moment when he clicks the button to get the weight data; Automatically judge whether the weight data is stable, and it is not allowed to take weight data when it is unstable. In order to prevent internal and external collusion and cheating, the gross weight and tare weight are automatically read into the system without manual input.
