acquiring a moving amplitude difference value and a reciprocating distance difference value of the detection force arm, and comparing the moving amplitude difference value and the reciprocating distance difference value of the detection force arm with a moving amplitude difference value range threshold value and a reciprocating distance difference value range threshold value respectively: if any value of the movement amplitude difference value and the reciprocating distance difference value of the detection force arm is not located in the corresponding range threshold value, judging that the operation of the corresponding detection force arm is abnormal, generating a detection signal of the detection force arm and sending the detection signal of the detection force arm to a mobile phone terminal of a maintainer; after the maintenance personnel finish the maintenance, the maintenance duration and the initial time are sent to a database for storage;
and if the moving amplitude difference value and the reciprocating distance difference value of the detection moment arm are both located at the corresponding range threshold value, judging that the operation of the corresponding detection moment arm is normal, generating a normal operation signal and sending the normal operation signal to the controller.
