摘要：
In order to Real-time monitoring of vehicle load status, device for measuring suspension displacement with overload protection function had been operated on collecting information of vehicle axle load in this research, then the axle load signal with noise was filtered by using the EMD method and steady-state values of load were obtained. A monitoring system of vehicle load status was designed on FAW truck based on above key technologies. the system uses the vehicle terminal microcontroller acquisition and processing axle load voltage signal which sensor output, processed load information was output to the PC and displayed by the Human-Computer Interaction to achieve the purpose of real-time monitoring of the load status. Finally, system was tested in the conditions of different load, speed, type of road; measurement error is less than 5% that meet the requirement of real-time monitoring of vehicle loading status. This research laid the foundation for follow-up development of vehicle early-warning technology.
