Fault detection system, method and device of mine electromechanical equipment

The embodiments of the invention disclose a fault detection system, method and device of mine electromechanical equipment. The fault detection method includes the following steps that: vibration signals are acquired through an ICP vibration acceleration sensor signal conditioning circuit, and an analog band-pass filter performs harmonic wave detection; sensor signals are acquired through a branch station, and the sensor signals are packed so as to be uploaded to the diagnosis software of an upper computer; a vibration spectrum is analyzed through the diagnosis software, and fault symptom information is obtained through the fast Fourier transform algorithm; high-order harmonic waves generated by current flowing to electrical equipment and a driver and the response characteristics of the abnormality and degradation degree of harmonic wave method equipment are obtained through harmonic wave method equipment fault diagnosis technology; and fault symptom parameters which are obtained through acquisition and signal
