Description

Data correction method for load sensor

Technical Field

The invention belongs to the field of weighing, and particularly relates to a data correction method for a load sensor.

Background

The weighing of truck loads has been done by truck pounds. And the weight that a weighbridge can weigh is only a transient condition. When the truck leaves the weighbridge, the weight of the cargo may change, creating an error between the actual weight and the weighing of the weighbridge, such as a sand truck, which is prone to escape. The longer the way the transport is, the more significant the error in the weighing of the actual weight and the weighbridge may be. At the moment, the load sensor for loading the truck appears, and the load sensor converts the weight of the loaded truck into an electric signal so as to achieve the purpose of monitoring the actual weight of the loaded truck in real time. Although the load sensor can monitor the loading of the vehicle, the error rate is very high, the monitoring purpose can only detect whether the vehicle suddenly changes a series of actions with very large weight such as changing goods, unloading goods, bunching goods and the like midway, and the weight of the actual goods cannot be accurately measured. And most load sensors are easily interfered by a series of environmental factors such as terrain, slope, inertia and the like, and the weight of the actual goods is influenced and measured.
