[0115] If it exists, obtain the filling rate error, determine the numerical display error rate based on the filling rate error and the filling rate, and determine the tank weight difference of the target loading and unloading tank truck based on the data value display error rate;

[0116] Based on the tank weight difference, the tank filling end value of the target loading and unloading tank truck is adjusted;

[0117] The unloading monitoring unit is used to obtain the historical unloading time of multiple tank trucks of the type corresponding to the target loading and unloading tank truck for comparison when the loading and unloading state of the target loading and unloading tank truck is the unloading state, so as to obtain the unloading approaching interval;

[0118] When the unloading time of the target loading and unloading tank truck reaches the unloading approaching interval, real-time weighbridge data is collected. When the real-time liquid flow in the crane pipe is less than the preset value, the current weighbridge value is obtained;

[0119] Compare the current weighbridge value with the target tank truck weight.
