This paper focuses on the weakening or eliminating low frequency dynamic load of vehicle dynamic weighing, improve the efficiency and accuracy of dynamic weighing system, weighing the purpose of. Wireless sensor network is deployed in the monitoring region of sensor nodes, the nodes achieve interconnectivity through wireless communication protocol, the network system structure. Usually, information without knowing the corresponding node position, often meaningless, positioning plays a very important role in many applications of wireless sensor network. Based on dynamic load model, load WSN-WIM system design, signal processing, in-depth research of sensor fault diagnosis. Methods to investigate the dynamic load processing based on WSN. The cooperation of each sensor nodes through the use of sine fitting algorithm based on three parameter sine wave curve fitting of the dynamic load, a set of linear equations, using efficient algorithm and information processing method of improving weighting precision. Study on sensor fault load based on grey prediction theory. In the WSN-WIM system, sensor calibration is a key problem, which put forward the optimization scheme of weighing sensor fault diagnosis method and grey prediction model based on the grey prediction theory, improving the weighing accuracy and system stability of WSN-WIM system.
