the stress condition of the pressing sheet on the sensor (303) is calculated according to the formula, the total mass of the material is calculated according to the stress direction of the pressing sheet, the pressing sheet of the sensor (303) is assumed to be a circular film during calculation, and is calculated by taking the circular film as an equivalent model, a coordinate system is built in a flat state of the pressing sheet of the sensor (303) during setting the equivalent model for convenient calculation, the component force of the pressing sheet with the pressure value T in the z-axis direction is obtained, and the total weight of the material is calculated by the following formula
Obtaining the total weight M of the materials; wherein g is gravitational acceleration; x, y and z are respectively coordinate values of the extreme positions of the compression deformation, the total weight M is calculated, and then the rated mass born by the first spring (3) is added to obtain the actual material mass M Real world Maximum mass M which can be hoisted by the motor (205) max Comparing when M Real world ≤M max When the weight of the material is within the rated range of the motor (205), when M Real world >M max When it is determined that the motor (205) cannot load the current weight of the material.
