Clutch failure detection method, system and equipment based on current characteristics and medium

The invention provides a clutch failure detection method, system and device based on current characteristics and a medium. Current detection is conducted on a detected motor, a Hall current sensor is used for conducting current detection on the detected motor, a voltage signal is output, and the output voltage signal is collected through a data collecting device and input into a controller for data processing; and motor current characteristic s and clutch braking performance are subjected to characteristic correlation, and clutch braking performance data are obtained through a waveform fitting algorithm in data processing of the controller. The brake performance of the clutch is obtained by detecting the current of the motor, online detection of the brake effect of the clutch is achieved, the number of transmission teeth of the ratchet wheel is obtained by utilizing the current of the motor through data processing of the controller during detection of the current of the motor, and the stress condition of the
