Background
With the subdivision of domestic trucks and the refinement of markets, the markets corresponding to different varieties and axle numbers are different, and the total mass of vehicles with different axle numbers is different according to the requirements of regulations. For example, a vehicle with a drive format of 6x4 is strictly limited to 25 tons, a vehicle with a drive format of 8x4 is strictly limited to 31 tons, a vehicle with a drive format of 8x4 may be suspended to 32 tons, and a vehicle with a drive format of 6x4 traction +3 axles is limited to 49 tons. The overload of the vehicle not only damages the road surface, the bridge and other facilities to a certain extent, but also affects the driving stability, the braking performance and other vehicle safety performances of the vehicle, and is very easy to cause a plurality of unstable factors. Therefore, vehicle overrun and overload are important problems to endanger road traffic safety.
However, not all markets strictly require the device goods according to the regulations, most vehicles do not adopt related technical equipment to remind the vehicle owners of the gross weight of the vehicles in time, and the vehicle owners cannot check the gross weight of the vehicles anytime and anywhere. In the traditional market, the vehicle is weighed by driving the vehicle to a wagon balance, so as to measure the total weight of the vehicle and further determine whether the vehicle is over-limit and overloaded. Meanwhile, some markets load goods according to the size of a cargo compartment and by combining the experience of a driver, but sometimes the density of the goods is high, the weight of the vehicle cannot be accurately controlled within the weight range allowed by the regulations, so that the problems that the vehicle is overloaded and goes on the road and the vehicle is forced to unload due to the fact that the vehicle is overloaded and cannot go up at a high speed are caused. Additionally, the long-term frequent overload of the vehicle can cause abnormal damage to the vehicle and increase maintenance costs. Meanwhile, when the vehicle is used very much and is damaged abnormally, the vehicle manufacturer has no relevant evidence to prove that the reason for the damage of the vehicle is that the vehicle is used abnormally, and the vehicle manufacturer can only undertake the paying responsibility of the abnormal damage.
