In the control module 1. The PLC control device 11 uses a PLC (programmable logic controller) of Siemens series model number S7-200smart ST 40. The existing common assembler program is used for control. The assembler is formed by combining a main program, a subprogram and an alarm program. The man-machine interaction device 12 is a touch screen display, adopts the existing Wenlong configuration software to edit the screen of the touch screen, uses the screen model MT6071/IP (800 × 480), combines with the PLC control device 11 to compile an operation screen, and is divided into three sub-screens, namely a user login interface, a system operation interface and a parameter setting interface. The user operation interface is provided with two different operation levels, namely an operator and an administrator, for setting different user permissions, the operator can only normally operate the opening or closing of the plurality of rolling doors 21 in the subway station, and the administrator can control the plurality of rolling doors 21 in the subway station to modify different parameters, such as the opening and closing speed of the rolling doors 21 and the opening and closing time of the rolling doors 21. And in a system operation interface, the real-time state of the rolling door 21 during operation can be monitored by pictures, and virtual keys such as manual and automatic switching, starting, stopping and the like are provided. And the parameter setting interface is used for monitoring input and output signals related in the system in real time so as to facilitate troubleshooting, and meanwhile, parameters such as the speed of the roller shutter door 21 and the like can be revised so as to realize more humanized operation.

The human-computer interaction device 12 can be installed in the master control room according to the field situation by the operator and the human-computer interaction device 12.

The warning device 23 includes a voice reminding unit 231 and a video reminding unit 232. The voice reminding unit 231 is integrated by a voice alarm and a warning lamp and is arranged at the outer striking position of the rolling door 21. When the passenger enters the subway station by mistake outside the set time, the voice broadcast' the subway stops running and does not enter! ", reminding passengers not to enter the subway station. The video reminding unit comprises an LED display screen, and the display screen is installed on a door frame of the rolling door. When the set time is up, the rolling display shows that if the last train has been dispatched, the passenger does not need to enter the subway station, selects other travel tools, and thank you for coordination (a specific prompt statement can be set in the man-machine interaction device 12 according to requirements), so as to achieve the humanized treatment and avoid the phenomenon that the passenger may not enter the subway station.

Fig. 3 is a main circuit diagram of door 1, which includes an inverter, a motor and a 24V power module. And part of wiring terminals of the PLC control system and the touch screen display in the human-computer interaction device 12 are powered by 24V direct current.

Fig. 4 is a PLC wiring circuit diagram of gate No. 1, in which a PLC wiring diagram of all input and output terminals with respect to gate No. 1 is shown.

Fig. 5 is the circuit diagram of the speech alarm of door No. 1 of the utility model, the concrete wiring schematic diagram of the speech alarm is given in the figure, and the function interconnected with the PLC is provided simultaneously.

As shown in fig. 6, the main program of the assembler program in the PLC control device 11 is shown.

Firstly, the system is powered on, a 'start' button on a touch screen is clicked, system initialization is carried out, a self-checking program is carried out, and if the self-checking program fails, the system is shut down and alarms. And the self-checking is passed, and a subprogram is entered for operation. With respect to the subroutine setting, there may be several gates depending on the field, thereby assembling an increased number of subroutines.

As shown in fig. 7, the subroutine of the assembler program in the PLC control device 11 is shown.

The subprogram is initialized firstly, then manual/automatic program switching is carried out, when the system switches the manual program, the roller shutter door 21 can be freely opened and closed, and the requirement of stopping the current action in real time is met. When the system switches the automatic program, the system is manually switched to an automatic mode to operate, whether a signal is output or not is detected, and the next operation can be carried out when the system meets the system requirement; when the time parameter (time node for opening and closing the roller shutter door 21 is specified) is set by an operator, the three-phase motor rotates reversely when the specified opening time is reached, the roller shutter door 21 is lifted at fixed time, and when the roller shutter door 21 reaches the upper limit, the three-phase motor stops working and the roller shutter door 21 is in a completely opened state; when the specified closing time is reached, the monitoring device 22 detects whether a person passes through the opening of the roller shutter door 21, if no person enters the opening, the three-phase motor rotates forwards, the roller shutter door 21 is automatically closed, the lower limit is reached, the three-phase motor stops working, and the roller shutter door 21 is in a completely closed state. If someone wants to enter, the alarm lamp of the monitoring device 22 flashes and voice broadcast prompts passengers not to enter, the roller shutter door 21 stops immediately, and the roller shutter door 21 is closed in a delayed mode. If a person forcibly enters the roller shutter door, namely the first infrared sensor 221 and the second infrared sensor 22 both detect the person entering the roller shutter door, the alarm sound is increased, the worker is prompted to go to the evacuation, and the worker determines to close the roller shutter door 21.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
