The weighing platform for detection consists of a weighing module and a data collection and analysis device. The sensors detect the arrival of vehicles and the corresponding dynamic tire pressure. Using the collected data for analysis, the weight, speed, wheelbase and vehicle type of the vehicle can be estimated. It can be used to detect various parameters such as the number of vehicle axles, wheelbase, axle weight, vehicle speed, wheel spacing, and tire number. It has been applied in various scenarios including vehicle type classification, dynamic weighing, toll station weighing platforms, red light violation photography, parking area monitoring, traffic information collection, road monitoring, and airport taxiway monitoring.

The electronic scale of the garbage truck is provided with a mark for identifying the information of the garbage dumping place on each garbage can, and the information of the garbage can is read. Measure the weight of garbage can, store the weight of garbage in real time, and get the data to complete the data collection of garbage weighing. So as to realize the fine management of garbage.

The axle load scale is mainly composed of a PLC-based system and a lower-level computer system based on weighing instruments. The weighing system is mainly responsible for data acquisition and control of the hydraulic servo system. The system uses weighing sensors to detect the load of the four legs of the scale respectively, and converts the measured values through A/D conversion and transmits them to the PLC for comparison with the reference value. The comparison result is converted into the piston lifting control quantity of the servo actuator (including servo amplifier, servo valve, hydraulic cylinder, and lifting hydraulic cylinder) by the PLC algorithm and provided as control signals to the lower-level weighing instrument control program. Then, the control signal is output by the lower-level computer to adjust the lifting change of the hydraulic cylinder, thereby controlling the positions of the four actuators.

The weighing system of sanitation vehicle integrates weighing and rfid equipment to realize the weighing of articles and rfid automatic reading. A high-precision weighing sensor is adopted, which can accurately measure the weight of the trash can. When the trash can is lifted to a specified height, the weighing sensor will convert the weight of the item into an electrical signal and transmit it to the control system.

The weighing system for kitchen and bathroom vehicles utilizes RFID electronic tags with globally unique numbers. It organically combines RFID long-distance readers with electronic scales to form an intelligent weighing system. The control unit is respectively connected to each electronic tag, and the control unit controls the electronic tag and the electronic scale to cooperate for data statistics.

The electronic scale of sanitation vehicle adopts computer, RFID automatic identification technology and automatic identification control. With the rapid development of logistics waste storage industry, the effective management of receiving and sending garbage becomes particularly important.

The electronic scale of the garbage truck realizes the identity recognition of the garbage. The system dynamically collects the electronic license plate information of the trash can during the garbage lifting process. The automatic recognition function for the weighing and measurement of trash cans has been realized, and the automatically collected weighing data information is merged into the weighing management system.

The platform scale of the hopper is equipped with an automatic correction function for ratios. It monitors the deviation during the feeding process on the screen and automatically adjusts the feeding ratio according to the proportion of the formula to ensure the accuracy of the formula. Through parameter settings, it can automatically determine the amount of ingredients based on the production order, and the program can automatically modify the formula. It also has an automatic blowing function. After each mixing hopper machine has finished transporting the material, it automatically blows the material to avoid resin pipe blockage.

The weighing module realizes signal acquisition, processing, control and output based on digital intelligent module, industrial control computer and RS485 field bus, which constitutes a weighing system with high cost performance. The communication between on-site monitoring computer and management computer is realized by LAN. The software is programmed with VC++ by modular method.
