6. The subway screen door monitoring system according to claim 1, characterized in that: The rapid response system comprises a plurality of partition control modules built into a central controller (12) and adapted to the shielding door body (2), and the central controller (12) is also provided with a system control module, a platform control module, a manual control module, and a priority processing mechanism based on the manual control module.
7. The subway screen door monitoring system according to claim 1, characterized in that: A plurality of alarm buttons (31) adapted to the shielding door body (2) are fixedly connected to one side of the shielding wall (1), a guide display screen (32) is fixedly connected to the bottom of the movable slider (6), a loudspeaker (33) is fixedly connected to one side of the guide display screen (32), and a receiver (34) is fixedly connected to the other side of the guide display screen (32).
8. A subway platform screen door monitoring method, characterized in that: The method is applicable to a subway screen door monitoring system as described in any one of claims 1 to 7, and the steps of the method are as follows: S1: First, an infrared crowd detector (8) installed at a subway entrance is used to count the flow of people entering the subway station through each subway entrance in real time, and a central controller (12) is used to activate an indicator light (9) to indicate and guide passengers who are about to enter the subway station based on the result of the crowd count, so as to avoid excessive crowd gathering in front of a certain shielding door body (2); S2: When a large number of people suddenly gather in front of a shielding door body (2), the monitoring camera (14) captures image data through the transparent protective plate (15) and transmits it to the central controller (12), and the central controller (12) analyzes the image data to determine whether there is an emergency situation, and then controls the mobile component to drive the compensation camera 7 to quickly move to the crowd gathering area to enhance monitoring efforts; S3: When a problem that is difficult to solve occurs in the crowd, the passenger can trigger the alarm mechanism by pressing the alarm button (31). Thus, after receiving the alarm information, the central controller (12) remotely connects to the control terminal of the staff through the guide display screen (32), and uses the loudspeaker (33) and the receiver (34) to achieve two-way communication, so as to take timely response measures; S4: When the monitoring camera (14) has an image acquisition failure, the central controller (12) moves the compensation camera (7) to the front of the faulty camera through a moving component to perform image acquisition and analysis on the surface of the transparent protective plate (15); S5: If the analysis result shows that there is an obstruction on the surface of the transparent protective plate (15), the central controller (12) will issue a warning to the staff and instruct them to clear the obstruction; S6: If the analysis results show that there are stains on the surface of the transparent protective plate (15), the central controller (12) controls the cleaning mechanism to start. First, the cleaning liquid in the cleaning liquid storage tank (21) is sprayed onto the cleaning sponge roller (20) through the micro spray pump (25) to soak one end of the cleaning sponge roller. Then, the cleaning motor (18) is started to drive the cleaning screw (17) to be threadedly connected with the cleaning slider (19), and the cleaning sponge roller (20) is driven to move along the length direction of the cleaning screw (17) and scrub the surface of the transparent protective plate (15). Finally, the cleaning sponge roller (20) that has completed scrubbing is moved into the receiving frame (22) to prevent the cleaning liquid from dripping onto the crowd.
