It also comprises the station comprehensive monitoring system, carries out communication by Modbus TCP communications protocol between station comprehensive monitoring system and industrial control computer.
It also comprises long distance control system PSA, and long distance control system PSA is connected with industrial control computer by bus.
The utility model has the advantage of:
1. every side safety door control system at each station overlaps independently circuit controls by one, guarantees that the fault of the safety door of either side does not affect the normal operation of opposite side safety door, and the fault at a certain sect does not affect the normal operation of other safety door of homonymy.
2. the design of RACS has taken into full account safety, reliability, maintainability, availability and extensibility, follows modular design principles, and is simple in structure, easy to installation and maintenance.
3. the hardware of control system all adopts production technology advanced in performance, technical maturity, and door steady quality, reliable and good looking appearance in use ensures safety.
Description of drawings
Fig. 1 is system architecture schematic diagram of the present utility model;
Fig. 2 is circuit connection diagram of the present utility model.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing, but the content that the utility model is protected is not limited to the following stated.
As shown in Figure 1, the rail transit safety door control system, comprise central interface panel PSC, local control panel PSL, emergency control panel PEC, door control unit DCU and signal system interface SIG, described central interface panel PSC comprises industrial control computer, logic control unit PEDC and relay group;
Industrial control computer is connected by Ethernet switch andlogic control parts PEDC, logic control unit PEDC is connected with door control unit DCU by bus, and the relay group is connected with door control unit DCU, emergency control panel PEC, local control panel PSL and signal system interface SIG respectively.
Logic control unit PEDC is divided into up logic control unit PEDC and descending logic control unit PEDC, the relay component becomes up relay group and descending relay group, signal system SIG is divided into the upward signal SIG of system and the downstream signal SIG of system, local operation dish PSL is divided into up local operation dish PSL and descending local operation dish PSL, emergency control panel PEC is divided into up emergency control panel PEC and descending emergency control panel PEC, up parts are connected with the safe gate cells D CU of track one side, and descending parts are connected with the safe gate cells D CU of track opposite side.
Described logic control unit PEDC is PROFIBUS DP fieldbus with the bus that is connected between door control unit DCU.
It also comprises the station comprehensive monitoring system, carries out communication by Modbus TCP communications protocol between station comprehensive monitoring system and industrial control computer.
It also comprises long distance control system PSA, and long distance control system PSA is connected with industrial control computer by bus.
Interface between signal system and station platform safety door meets " failure safe " principle.Except responding effectively " opening the door " order, the fault that is caused by any parts damages can not cause opening the door.After release, the fault of any parts can not hinder with any one door of manual unlocking.
System-level control: under normal circumstances, the safety door system level is controlled temporarily by carry out the opening-closing door straighforward operation of platform sliding door by the wireless remote control control mode, and what receive that signal system provides comes to a complete stop, stops the definite message or answer breath, as the unlatching of safety door or close condition.I take charge of the relevant interface that the preserved signal system interlink is controlled, and access when condition maturity.
The platform level is controlled (local control panel PSL control): when system-level control can not normally move, under the abnormal conditions such as signal system fault, signal system and safety door system communication disruption, safety door system local fault, the station affair personnel can carry out the opening-closing door operation of safety door by PSL, realize the platform level operation of safety door.
Emergency control panel PEC controls: control when system-level control and platform level and break down, in the time of can not normally moving, can carry out the opening-closing door operation of platform sliding door by the emergency control panel PEC that the station staff operates the indoor setting of car control.
The single door local operation: in the maintainability test situation, the single door local operation is by the repair and maintenance personnel, the single track safety door to be operated.When control box on the spot turns to manually or during isolation, this sect breaks away from safety return circuit from automatic control shelves by private key, safeguard that the repair and maintenance personnel can operate the single track door by the switch gate button that arranges on control box on the spot.
Manual unlocking: manual unlocking is the emergency operation that platform staff or passenger carry out sliding door.When system power supply or indivedual safety door operation mechanism broke down, the platform staff can open sliding door with the key release in platform side, and perhaps the driver uses manual unlocking device unlatching sliding door on safety door by broadcast announcement passenger in car.
Control under above-mentioned five kinds of operational modes has the priority processing function, i.e. manual unlocking operation has limit priority, and system-level control priority is minimum.
