Abstract

Temperature is an important factor affecting the weighing accuracy of the piezoelectric thin film Weigh-in-Motion (WIM) system. Because the temperature compensation coefficient formula given in the existing technical data is not effective in practical application, and because the time and cost factors can not be used to calibrate the compensation coefficient of each temperature one by one, this paper studies the law between temperature and weigh-in-motion accuracy. The calibration coefficients were calculated by using the least-squares linear fitting method at two temperatures, and the compensation coefficients were calculated for all the temperature gradients. This not only reduced the test time and cost, but also to obtained a high weighing accuracy. The reliability and validity of the proposed method were proved by the experimental results and the actual test results.
