b: when a motor car passes through the main body detection area (1), the motor car is detected by the car body running state detection assembly (3), the second detection area (5) is formed through the horizontal and angle deviation of the deviation detection wheel (33) to collect data, the phenomenon that the whole deviation phenomenon possibly occurs is judged to occur when the deviation value is abnormal, and the whole judgment is made according to the analysis of the data collected by the first detection area (4) and the second detection area (5);
c: when a motor car enters a station area, the motor car can slowly pass through the lifting degree monitoring assembly (6), if the phenomenon that a metal plate at the bottom of the motor car is locally lifted occurs, the lifting piece is contacted with the surface contact detection point (65) according to the inclined height of the stressed movable plate (62), the length of the lifting piece is judged according to the contacted position, meanwhile, the stressed movable plate (62) is caused to move in the connecting frame (63) under the action of the lifting piece, and the quantity of the lifting piece is analyzed according to the quantity of the motion of the stressed movable plate (62).
