According to the above description, in an exemplary embodiment, the platform controller is further connected with a platform end control box, a local control box and an operation indicator panel; the platform end control box is arranged at two ends of each side platform, the local control box is arranged at the shield door, and the operation indicating disc is arranged in a station comprehensive control room and used for displaying the opening and closing state and fault information of the shield door. As shown in fig. 3, the single station shielding door control system mainly comprises a main control computer (i.e., a station HMI), an input/output module, a station end control box PSL, a shielding door control unit DCU, a local control box LCB, an operation indicator panel PSA, and a redundant bus network, wherein the bus network connected with the station shielding door control unit adopts a dual-bus redundancy technology. Wherein, the PSL is positioned at two ends of each side platform and is used for the control of the platform level; the LCB is positioned at the door head on the right side of each shielding door and is used for manual operation; the PSA is arranged in a station comprehensive control room, displays the switch state and fault information of the shielding door, and can also realize station level control. When a signal system in the platform HMI confirms that the stop position of the train is in an allowable range, a door opening command is sent to the PLC, the PLC sends a command to the DCU to control the action of the motor, and the automatic opening and closing of the shielding door are controlled by the sequential operations of unlocking, opening the door and the like.
In summary, aiming at the problems that the shield door of each station only has a local monitoring system, the distance between the stations is long, and no association exists between the shield doors of each station, the method is based on a single station shield door equipment control system, designs a set of multi-station shield door centralized monitoring system, and designs a single station HMI program, so that the HMI program can access a monitoring system server through the internet, upload operation data and receive server instructions. The method breaks through the independent operation mode of the stations, not only realizes the centralized monitoring of all station screen doors, but also realizes the information sharing interaction between the screen door system and other subsystems of the track. The method is based on the original single-station shield door control system, network service programs are utilized, a database technology, a message middleware technology and a data caching technology are combined, the requirements of track traffic for centralized monitoring of the platform shield door, modification of part of operation parameters and storage of operation data are met, original independent operation substation equipment is linked, and centralized monitoring, centralized management and remote maintenance are achieved by the system. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
