Background
Platform doors are a barrier formed by a plurality of platform unit doors mounted on the platform edge to isolate the platform area from the track area, and are key components of a platform door system (Platform Screen Doors, abbreviated as PSD system). As shown in fig. 1, in the conventional PSD system 100, a door travel switch for acquiring status information and a DCU controller (Door Control Unit, a platform unit door controller, abbreviated as DCU controller) for controlling the opening or closing of the platform unit door are provided for each of the platform unit doors; wherein, the door body travel switches on all the platform unit doors of the platform doors on the same side are connected in series to form a first serial branch circuit 101, and the DCU controllers on all the platform unit doors of the platform doors on the same side are connected in series to form a second serial branch circuit 102.
As shown in fig. 1, the PSC controller 103 (Platform Screen Controller, platform door controller, abbreviated as PSC controller) of the conventional PSD system 100 is electrically connected to the CI controller 201 (Computer Interlocking Controller, computer interlock controller, abbreviated as CI controller) of the SIG system 200 (SIGNALLING SYSTEM, abbreviated as SIG system) by a combination of a safety relay and a hard-wire cable. The PSC controller 103 is connected with the CI controller 201 through a first relay cabinet 104, a first branch cabinet 105, a second branch cabinet 204, a second relay cabinet 203 and an interface cabinet 202 in sequence, the first relay cabinet 104 is connected with the first serial branch 101 through a hard wire to obtain state information, and the first relay cabinet 104 is also connected with the second serial branch 102 to control the door machine in the platform unit door to act; meanwhile, the PSC controller 103 is connected to the second serial leg 102 through a data communication line to collect control information of the station cell door.
As shown in fig. 2, a schematic diagram of the PSD system 100 sending commands to the SIG system 200. As shown in fig. 1 and 2, taking a single-side platform as an example, a platform door status relay 106 and an interlock release relay 107 are arranged in the first relay cabinet 102, the platform door status relay 106 is driven by a circuit formed by connecting a travel switch and a door locking point of each platform unit door body in series in the single-side platform door, and the interlock release relay 107 is driven by an interlock release switch formed by an in-situ control switch point arranged outside the platform door; when all the platform unit doors in the single-side platform door are closed and locked, the PSD system 100 sends the closing and locking state information of the platform door to the SIG system 200 through two groups of contacts of the platform door state relay 106, and the CI controller 201 drives the platform door state reset relay 205 through a circuit formed by the contacts, so that the SIG system 200 obtains the platform door state information of the single-side platform; when the interlock release switch is closed, the PSD system 100 sends an interlock release command to the SIG system 200 through two sets of contacts of the interlock release relay 107, and the CI controller 201 drives the interlock release relay 206 through a circuit constituted by the contacts, so that the SIG system 200 acquires the interlock information of the one-sided station.
As shown in fig. 3, the SIG system 200 is schematically illustrated as sending commands to the PSD system 100. As shown in fig. 1 and 3, taking a single-sided station as an example, a door opening relay 207 and a door closing relay 208 are provided in the second relay cabinet 203, driven by the CI controller 201; SIG system 200 sends a door opening command to PSD system 100 through two sets of contacts of door opening relay 207, PSD system 100 drives a door opening reset relay 108 through a circuit formed by the contacts, so that the DCU controller controls all platform unit doors in the single-side platform door to be opened; the SIG system 200 sends a door closing command to the PSD system 100 via two sets of contacts of the door closing relay 208, and the PSD system 100 drives a door closing reset relay 109 via a circuit formed by the contacts, so that the DCU controller controls all the platform unit doors in the single-sided platform door to be closed.
Because the existing PSD system 100 and SIG system 200 are connected by combining a safety relay and a hard-wire cable and a hard-wire control interface is adopted, a large number of copper-core cables, safety relays and combined electrical elements are required to be consumed, which increases the complexity and fault point of the interface control circuit and increases the workload and difficulty of maintenance. In addition, the DCU controllers of each of the platform unit doors are connected in series, and when the SIG system 200 sends a door opening command or a door closing command to the PSD system 100, all the platform doors are opened or closed at the same time, so that the opening or closing of each of the platform unit doors cannot be precisely controlled, the platform doors cannot be aligned and isolated from the train doors, the safety of the platform doors is reduced, and the risk of an operation organization is increased.
