In the middle of the 80 s of the twentieth century, with the gradual maturity of high-precision weighing sensor technology, the mechanical wagon balance is gradually replaced by an electronic truck scale with high precision, good stability and convenient operation. The electronic truck scale utilizes the principle of strain electrical measurement to weigh. And a strain gauge is adhered to an elastic body of the weighing sensor to form a Wheatstone bridge. When no load exists, the bridge is in a balanced state, and the output is zero. When the elastic body is loaded, the strain proportional to the load is generated by each strain gauge, and the external load can be measured by the output voltage.

In the prior art, chinese patent publication No. CN106052827B proposes a practical electronic truck scale, in which the height of a roller is adjustable by a mounting shaft, so that when a climbing support frame is located at a position where a vehicle climbs, the roller is located above a plane where a lower end of a main body of the electronic truck scale is located, which not only facilitates movement of the electronic truck scale, but also reduces possible damage of the roller, and facilitates movement and vehicle weighing, but the electronic truck scale is the same as a conventional truck scale and does not have an effective early warning structure, so that an overloaded vehicle runs onto the truck scale and easily damages the truck scale body, and in life, a 50 ton truck scale often exceeds hundreds of tons of trucks, and the truck scale is bent after a long time, thereby shortening the service life of the electronic truck scale, and therefore the application discloses an electronic truck scale to meet the weighing requirement of the vehicle.
