Description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is a kind of electrical block diagram of embodiment of the utility model.
Specific implementation mode
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
As shown in Figure 1, a kind of railway platform screen door control system based on redundant manipulator comprising：ATC is used for
Export opening-closing door control instruction；PEDC for receiving the opening-closing door control instruction from ATC, and exports opening-closing door control letter
Number control shielding door switch；Shield door；Shield door redundant manipulator, for monitoring the opening-closing door control instruction from ATC and coming
From the ON/OFF gate control signal of PEDC, when detecting that the ON/OFF gate control signal of ATC is not consistent with ON/OFF gate control signal
When, substitution PEDC control shielding door switch；The shield door redundant manipulator controls shielding door switch by safety relay.Its
In, shield door can be that a fan can also be more fans.Shield door is monitored using shield door condition monitoring unit (ATC slave units)
Shutdown locking state, and by close the door locking status signal be respectively outputted to ATC and shield door redundant manipulator.The PEDC and
Shield door condition monitoring unit is arranged in PSCC cabinets, and unified management and circuit is facilitated to build.System further includes background monitoring
Unit, background monitoring unit are connect with shield door redundant manipulator by RS485 communication modes.Logout can be transmitted in real time
To background monitoring unit, background monitoring unit is classified and is stored to logout.
The groundwork process of the present embodiment is as follows：
The shield door redundant manipulator receives the enabling control instruction from ATC, and detects PEDC within a period
Gate control signal is opened in output, if PEDC does not export out gate control signal in the period, judges the ON/OFF gate of ATC
System instruction is not consistent with the ON/OFF gate control signal of PEDC；The shield door redundant manipulator receives the shutdown control from ATC
Instruction, and the detection within a period (period can be arranged according to actual needs, and 1S, 3S or 5S are set as in the embodiment)
The pass gate control signal of PEDC outputs judges the opening-closing door of ATC if the period inner shield door is not at shutdown state
Control instruction is not consistent with the pass gate control signal that PEDC is exported.Shield door redundant manipulator automatically engages operation (PEDC at this time
It is out of service from system), enable signal, ON/OFF gate control signal are sent out to shield door by safety relay, concurrently spoken
Light is alarmed.When shield door redundant manipulator puts into operation, after the door close commands that shield door redundant manipulator is sent out, for a long time (20
~120 seconds are adjustable) shutdown locking status signal is not received, sound-light alarm should be sent out.Sound-light alarm is realized by alarm unit, is reported
Alert unit can be alarm bell, siren, LED light etc., and the input terminal of alarm unit is connect with the output end of shield door redundant manipulator.
The realization of the microprocessors such as PLC chip or ARM chips can be used in shield door redundant manipulator.
In the present embodiment, the shield door redundant manipulator receives the opening-closing door from ATC by photoisolator and controls
Instruction；The shield door redundant manipulator receives the ON/OFF gate control signal from PEDC by photoisolator.Utilize photoelectricity
Isolator effectively realizes signal isolation, it is ensured that signal one-way transmission avoids shield door redundant manipulator to ATC and PEDC
Adversely affect.System further includes the power supply module for powering for PEDC and the PSL for manually controlling shielding door switch.
The output end of PSL and the input terminal of shield door connect.
The course of work of the utility model is described in detail by taking enabling failure and shutdown failure as an example below：
Enabling troubleshooting process：
Shield door is closed at this time, and the enabling control instruction of ATC outputs, PEDC and shield door redundant manipulator are same
When receive enabling control instruction, PEDC does not export enabling drive signal (opening gate control signal) since failure does not execute, shielding
Door redundant manipulator detects that shield door, still in closed state, judges ON/OFF in 3S by shield door condition monitoring unit
Door control instruction is not consistent with shielding door opening and closing state, and the switching signal output end of shield door redundant manipulator exports switching signal
PEDC power supplys are cut off, and exports enabling drive signal (opening gate control signal) control shield door and opens.The drive signal includes
Opening the door allows signal, enabling signal；When needing to open the door, first sending out enabling allows signal, then sends out enabling signal, two signals
Shield door is opened when being provided simultaneously with.
Shutdown troubleshooting process：
Shield door is in open state at this time, and the shutdown control instruction of ATC outputs, PEDC and shield door redundant manipulator are same
When receive shutdown control instruction, PEDC does not export shutdown drive signal (close gate control signal), shielding since failure does not execute
Door redundant manipulator detects that shield door, still in open state, judges ON/OFF in 3S by shield door condition monitoring unit
Door control instruction is not consistent with shielding door opening and closing state, and the switching signal output end of shield door redundant manipulator exports switching signal
PEDC power supplys are cut off, and output drive signal control shield door is closed.The drive signal includes opening the door allow signal, open the door and believe
Number；When need at closing time, first cancel enabling signal, shield door made to close, then cancel enabling allow signal.
In the embodiment, shield door redundant manipulator is after cutting off PEDC power supplys, the just directly work of take over PEDC, concurrently
Go out the train controlling center of alarm signal.After PEDC reparations, PEDC controls can be restored.
The utility model includes but not limited to following advantages：
1. can be greatly decreased influences train delays, late probability because of screen door control system (PEDC) failure when.
2, when screen door control system (PEDC) failure, it can replace online, not influence the normal operation of train；
3, background monitoring unit can pinpoint detection screen door control system (PEDC) and control signal, and preservation of classifying in real time,
Improve system trouble analysis efficiency.
4, there is replicability, only need rebuilding at low cost that this can be realized on the basis of existing screen door control system automatic
Redundancy control system function.
It is to be illustrated to the preferable implementation of the utility model, but the utility model creation is not limited to institute above
State embodiment, those skilled in the art can also make various etc. without departing from the spirit of the present invention
It with deformation or replaces, these equivalent deformations or replacement are all contained in the application claim limited range.
