Coal mining machine cable tension real-time detection device and method

The invention discloses a coal cutter cable tension real-time detection device and method. The coal cutter cable tension real-time detection device comprises a coal cutter body, a coal cutter main control module, a cable towing frame, a suspension assembly, a cable clamping plate, an angle sensor, a tension sensor assembly and a pressure rod assembly. The hanging assembly comprises a hanging ring body and a connecting piece, the hanging ring body is rotatably positioned and installed on the towing cable frame, and the lower end of the hanging ring body is connected with the cable clamping plate through the connecting piece; the angle sensor is used for detecting the rotation angle of the lifting ring body; the tension sensor assembly is assembled in the cable towing frame and can detect corresponding cable tension according to different rotation angles of the hanging ring body. The coal mining machine main control module can determine whether the coal mining machine body is stopped or not according to the rot
