Abstract

The invention discloses vehicle overload detecting system and method based on a CAN (Controller Area Network) bus, comprising a vehicle-mounted tracker installed on a vehicle and a monitoring center in wireless communication with the vehicle-mounted tracker. The vehicle-mounted tracker comprises a processor, a GPS module, a CAN bus communication module, a wireless communication module and a storage module. The invention also discloses a vehicle overload detecting method comprising the following steps of: collecting the real-time running information of the vehicle by using the CAN bus; collecting the position information and the speed of the vehicle by using the GPS module; transmitting data to the monitoring center by using the wireless communication module; and then calculating the load of the vehicle in the monitoring center by synthesizing the running information of the vehicle through the energy conservation law to judge whether the running vehicle overloads or not in real time. The invention can carry out whole-route, real-time and constant monitoring to the overload situation of the vehicle so that traffic policemen find the illegal overload situation of the vehicle to rapidly make alarms and treatment and eliminate overload accident potentials without influencing the normal running of other vehicles.

Description

technical field [0001] The invention relates to a detection system and a detection method for automatically detecting vehicle overload. Background technique [0002] In our country, the phenomenon of vehicle overloading is relatively serious. Overloading causes roads and bridges to be in overload operation for a long time, which not only seriously affects the power and service life of bridges, but also easily causes serious traffic accidents. The country has to invest a lot of manpower, material resources and financial resources every year to repair the road surface damage caused by overloading and control the overloading behavior, but the effect is still not satisfactory. [0003] The current detection method for vehicle overload is to set up overload detection points on national and provincial arterial highways, adopt a combination of fixed inspection and mobile inspection, and measure and identify manually. Authorized announcement number CN100342223C, the authorized anno...
