Research on multi-sensors signal process of microcomputer batching system

Abstract：There are some shortcomings of low accuracy and reliability exsited in computer batch system, which direct impact the efficiency and credibility of enterprise.In the paper, firsty, the composition of microcomputer burden system is introuduced, the analysis on the reason that affects weighing accuracy in multi-sensors parallel connection is done and some solutions are given.Then, by combing with the practical system, the weighting system structure is improved, a method that series resistor in sensor input to adjust balance is proposed and the measuring amplification circuit is designed.Finally, fuzzy creep compensation and digital filter are presented in this paper.It is proved to be an efficient and simple approach to improve the accuracy of weighting, and greatly improve the measuring accuracy and stability.
