Embodiment Construction
[0051] The method, system and device for judging vehicle overload based on BP neural network of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0052] Such as figure 1 Shown, the present invention is based on the vehicle overload discrimination method of BP neural network, comprises:
[0053] (1) Overload source data preparation process
[0054] The original data is vehicle positioning data (including license plate number, driving time, longitude, latitude, speed, etc.), CAN bus data collected by OBD (including time, speed, speed, engine load, expected engine speed, instantaneous fuel consumption) and vehicle operation conditions Table (including license plate number, vehicle type, operating time, loading location, unloading location, cargo weight).
[0055] Preprocess the vehicle positioning data, CAN bus data and vehicle operation conditions to obtain overload source data (including license plate number, time, ...
