Abstract: For the dynamic monitoring and early-warning of abnormal vehicle loading in the internet of things (IOT), an accurate detection device was developed based on displacement sensor with overloaded protection. Based on dynamic suspension characteristics, a data processing algorithm for measured signals of suspension deformation by the displacement sensor was compiled with the empirical mode decomposition to solve dynamic loading status of moving vehicle. A test platform was built upon FAW Jiefang heavy truck and UNO2170 industrial computer of Advantech combined with GPS and GPRS. After repeated tests, this system can accurately detect the overload status of moving vehicle with errors are less than 5% of total weight of vehicle, providing the technical support for the development of IOT.

Key words: engineering of communications and transportation safety, overload, displacement sensor, dynamic monitoring and early-warning, internet of things(IOT)
