For most national and provincial roads, vehicle weighing equipment is not equipped at present, and the load spectrum condition of the road section needs to be studied deeply. The vehicle weighing equipment is divided into a fixed type and a portable type according to the installation mode, fixed detection is immovable, the manufacturing cost is high, the problems of avoidance of inspection by detouring of an overloaded driver and the like exist, and the requirement of vehicle load spectrum testing cannot be completely met; in comparison, the portable weighing equipment is convenient to install, can process suspicious vehicles on roads at any time and any place, and has wider application prospect. According to the measurement principle, the vehicle weighing device is divided into two modes of static detection and dynamic detection. The static method requires the vehicle to be stationary on the measuring device, and the method has high accuracy, but has a problem of slow vehicle detection speed, and particularly, the method is easy to cause road congestion on a road section with a large traffic flow. The dynamic mode can measure in the dynamic running of the vehicle, and the installation and the operation are simple and easy, so the mode has the advantage of high measuring efficiency, but the measuring precision is reduced.
