Aiming at the requirements of vehicle weighing accuracy and shaft type recognition rate in the highway toll system, by analyzing the characteristics of the full-vehicle dynamic weighing platform structure and weighing process,this paper put forward the wiring scheme of cantilever beam strain bridge weighing sensor and the hardware and software design solutions of full-vehicle dynamic weighing instrument.The segmentation of axle increasing process to identify axles and calculate single shaft weight based on the expert algorithm and the software implementations based on the embedded real-time kernel μC/ OS-Ⅲ were also discussed. The result shows that the instrument not only improves weighing accuracy and can accurately identify the vehicle axis without the aid of auxiliary equipment.
