The Electronic scale of the conveyor belt adopts a weighing and measuring device for fixed-length weight measurement. It measures the tested material in segments, and the length of the material measured in one weighing is the length of the belt. The weight of the material is calculated and processed to obtain the weight. Given the above Measurement system uses a weighing module with piezoelectric crystal elements as the weight signal measurement conversion element, and the weighing instrument as the core component of the data acquisition, signal processing and calculation in the weighing device, it realizes online dynamic detection and display. On the other hand, the software method is used to perform digital filtering on the signals sent by the weighing module to reduce the difficulty of motor control circuit design and the impact of component performance on the circuit due to changes in temperature and humidity, so as to filter out the low-frequency vibration and interference signals, further improving the measurement accuracy and achieving good results.

The electronic scale of the conveyor belt is based on a new type of online dynamic real-time Weighing system for conveyor belts. It uses the weighing module for weighing data collection and completes the filtering, calculation and display functions of the weighing data through software. The weighing module drives the motor and the data acquisition system. In the processing of measurement data, two methods of parameter identification and numerical integration are combined. The current widely used graphical language programming test software is used for data processing, display and the realization of related functions.

The electronic scale of the conveyor belt consists of a weighing module, a motor, a frequency converter and a control system. The conveyor and the belt conveyor are driven by frequency motors. The conveyor is installed with a lever device under the continuous running belt. When the material on the belt passes over the bearing surface of the lever device, it will exert a certain pressure on the bearing surface. The pressure is transmitted to the weighing module through the lever device and the control device amplifies and processes the weight pressure signal sensed by the weighing module and displays it in digital form. At the same time, the digital signal displayed can be externally controlled. The scattered material flow signal detected and the set flow signal are compared in the control system, and PID is used for regulation to drive the frequency converter to change the speed of the conveyor and the belt conveyor motor, automatically change the speed of the belt according to the actual required feeding amount, track the given feeding amount, and thus form the control characteristics of feeding more, the speed slows down; less material, the speed speeds up; when overloaded, it is the slowest or even stops. Thus, the given material flow is achieved.
