Abstract:
     The present invention relates to a high-speed dynamic vehicle overload detection method based on bridge strain, belonging to the field of detection technology. Said invention uses strain sensor as field sensing device to measure bridge surface strain due to running vehicle, and utilizes integral operation to eliminate the influence of vehicle vibration on the calculated result so as to further obtain load weight value, then utilizes aid load weight value to compare it with standard load weight value pre-stored in data base so as to judge overload of said vehicle.
