Along with the continuous improvement of the living standard of urban residents, the corresponding purchasing power is correspondingly improved, and therefore, the quantity of the generated household garbage is increased year by year. Therefore, in order to strengthen scientific operation management of urban household garbage, the aim of reducing garbage discharge is well established by charging according to the weight of single-barrel garbage from the source of garbage manufacturing, and therefore a weighing system or a device is required to be arranged on a garbage truck.

In a conventional weighing system or apparatus, a situation that an actual value is inconsistent with an actual value due to eccentricity or inclination (such as being installed out of level or not vertical) of a force direction of a weighing sensor may occur, so that a phenomenon that a weighed object is misaligned due to a large error may be caused. The reason is that the weight of the weighed object comes from vertical downward gravity, and once the stress direction of the weighing sensor is inconsistent with the road surface where the weighing sensor is located, a lateral gravity value (namely parasitic lateral force) can be generated, so that the weighing result is influenced. However, since the weighing system or device is not particularly precise instruments and devices when applied to some occasions and under severe outdoor conditions, once too many different types of sensors (such as angle sensors) are installed during the operation, the failure of the sensors is likely to be frequently caused by the influence of external factors (such as corrosion of sewage, impurities and the like), and finally the weighing system or device cannot be normally used.
