Mechanical equipment fault diagnosis system and method

The invention discloses a mechanical equipment fault diagnosis system and method, and the system comprises an initial module which is used for setting a detection period of mechanical equipment and collecting a vibration signal of the mechanical equipment in the detection period; the judgment module is used for judging the state of the mechanical equipment according to the vibration signal; if the mechanical equipment stops, the judgment module reports a shutdown signal and enters the next detection period; and if the mechanical equipment is in operation, the judgment module judges whether the mechanical equipment is in high-frequency early warning or low-frequency early warning, if not, a normal signal is reported, if the mechanical equipment is in high-frequency early warning, a high-frequency fault signal is reported, and if the mechanical equipment is in low-frequency fault, a low-frequency fault signal is reported. 本发明公开了一种机械设备故障诊断系统及方法，系统包括：初始模块，初始模块用于设置机械设备的检测周期并采集机械设备在检测周期内的振动信号；判断模块，判断模块用于根据振动信号判断机械设
