The working principle of weighing module and the way of strain gauge assembly, the data acquisition system consists of lower computer hardware and upper computer software. The software adopts programming technology to obtain the radial pressure of the wheel on the tilting table, and the strain gauge under the tilting table is strained due to the force. The lower computer obtains data signals. Through the serial communication module, the lower computer and the upper computer data acquisition system transmit instructions and data, process the collected signals, and convey the information to the user by the upper computer panel. This system has the functions of data acquisition and processing, and.

The nonlinear error compensation of the weighing sensor is completed based on the compensation network; In the lower limit region, a digital filter is used to complete the nonlinear error compensation. In the middle area, the weighing sensor does not compensate, and at the same time, the selection of subsection compensation is completed by using the adaptive selection network. The piecewise compensation model of nonlinear error is established to obtain good compensation effect.

In order to realize the static weighing measurement of large containers and hoppers in industrial environment, weighing module integrates weighing sensor, load transmission device, limit and overload prevention, and can be easily connected with various mechanical equipment. Based on the traditional resistance strain sensor, it has the functions of weight display, quantitative feeding, unloading, field equipment control, alarm signal display, formula setting and process monitoring. Combined with modern microelectronics technology and microcomputer technology, the weight display function is added with control function.
