ABSTRACT

In order to improve the accuracy and stability of the weighing system, under the actual conditions of rapid weighing of static truck scales, a design of weighing system based on improved moving average filter algorithm is proposed. The weighing system consists of data acquisition, analog-to-digital conversion module, processor, control module and display module. Being combined the median filtering method and the moving average filtering method, an improved moving average filtering algorithm that can eliminate occasional pulse interference signals and suppress periodic interference signals is proposed. Through the comparison and analysis of the experiment with the improved moving average filter algorithm, the weighing accuracy of the system optimized by the algorithm is effectively improved, and the display effect is faster and smoother.
