The invention discloses an automatic detection device of a traction
machine brake. The automatic detection device comprises a detection module, a short message module and a plurality of indicator lights. The detection module and the short message module are connected with an
elevator master controller, and
bidirectional communication is performed. The input end of the detection module is connected with all sensors of the
brake, the working state of the
brake is monitored constantly, and the output end of the detection module is connected with all the indicator lights. According to the automatic detection device of the traction
machine brake, CPU redundancy control of the
elevator controller is fully utilized, automatic detection and fault early-warning functions of the traction
machine brake are achieved, and cost is low. Compared with traditional detection, the automatic detection work is
safer, operation is more convenient, troublesome procedures of manually overhauling the brake by inspectors are omitted, the controller can automatically detect the working states of all parts of the brake through the automatic detection device, the repairing and maintaining frequency and the quality of an
elevator are easily ensured, elevator operation faults are greatly reduced, and elevator accidents are easily reduced.
