The invention discloses a linear motor air gap comprehensive early warning system and early warning method. The system comprises a data acquisition module, a data preprocessing module, an abnormity identification and analysis module and an early warning comprehensive analysis module. The data acquisition module comprises magnetic steel, a vehicle number label identification module and a sensor, the data preprocessing module preprocesses information acquired by the data acquisition module, and the abnormity identification analysis module analyzes whether abnormity exists in the preprocessed data or not; the abnormity identification and analysis module comprises a tooth number abnormity identification module, a tooth height abnormity identification module and a groove depth abnormity identification module. According to the method, the application safety level of the linear motor train is greatly improved, the scraping event of the motor and the induction plate in the operation of the linear motor is effectively prevented, the operation reliability and safety of a subway system are improved, and before a fault really occurs, the fault hidden danger is pre-judged and an alarm is automatically given; and the method has great significance on preventive overhaul and maintenance overhaul of the train linear motor.
