[0014] The present invention will now be described in further detail.
[0015] Such as figure 1 A method for verifying the weight of a belt scale equivalent to physical verification is shown, comprising the following steps:
[0016] Step 1: Under the condition that the parameters of the belt conveyor and its belt scale are the same as the external operating conditions (normal average load), respectively test the integration coefficients Ks and Km of the belt scale in the two verification methods of the physical object and the weight, where Ks is the actual object Calibration integral coefficient, Km is the calibration integral coefficient of weight M;
[0017] Step 2: Calculate the proportional coefficient K=Ks / Km between the two according to Ks and Km;
[0018] Step 3: When the belt scale needs to be calibrated during operation, use the last equivalent weight to calibrate the belt scale to obtain the current weight calibration cumulative coefficient Kxm; according to the cu...
