Description

Technical Field

[0001] The present invention relates to a rail transit signal system, and in particular to a device, an implementation method and an application method for releasing the interlock between a signal system and platform doors. Background Art

[0002] In the current urban rail transit system, when a platform door fails and the signal of "platform door closed and locked" cannot be sent out, the train cannot enter or leave the station normally. To solve this problem, a platform door interlock release device is usually configured between the signal system and the platform door system. This interlock release device has a self-resetting function, and the self-resetting is delayed on the signal system side or the platform door side. The delay time is usually adjustable between 15 and 90 seconds. When a power supply device failure occurs on the platform door side or a failure such as "PSDC dual-system" of the platform door occurs, the interlock release relay on the platform door side cannot be energized at this time, resulting in the invalidation of the interlock release function between the signal system and the platform door system, and the signal system cannot normally send an in / out station permission signal to the train.

[0003] After searching, Chinese Patent Publication No. CN111483473A discloses a method for detecting the platform gap and interlocking train operation. Specifically, it discloses that when the signal system determines that the train doors and platform doors are both closed and locked, it sends a start command to the gap detection system. The gap detection system feeds back the obstacle detection status to the signal system. After confirming that there is no obstacle staying therein, the signal system controls the train to leave the station, thereby effectively reducing the impact of the interlock on the operation efficiency and reducing the impact of false alarms of the gap detection system on the operation. At the same time, it supervises whether there is an obstacle during the train's departure from the station to ensure operation safety. However, this existing patent still cannot solve the problem that the interlock release between the signal system and the platform door is invalid due to the failure on the platform door side, which affects the normal operation of the train. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects existing in the above-mentioned prior art and provide a device, an implementation method and an application method for releasing the interlock between a signal system and platform doors, which solves the problem that the interlock release between the signal system and the platform door is invalid due to the failure on the platform door side, affecting the normal operation of the train.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] According to the first aspect of the present invention, a device for releasing the interlock between a signal system and platform doors is provided. This device is connected to the signal system. The device includes a platform door full-side bypass switch box, which is arranged on the signal system side. The platform door full-side bypass switch box includes platform door full-side bypass switches corresponding to each station site. By rotating the platform door full-side bypass switch corresponding to a certain station, the platform door full-side bypass relays of the platform doors on the up and down lines of a certain station can be activated or reset.

[0007] As a preferred technical solution, the full-side bypass switch of the platform screen door adopts a non-self-resetting switch with a key dedicated to rail transit and has two states, namely "trigger" and "reset".

[0008] As a preferred technical solution, the full-side bypass switch of the platform screen door is provided with a protective cover.

[0009] As a preferred technical solution, an indicator light is associated with each full-side bypass switch of the platform screen door. When the full-side bypass switch of the platform screen door is in the "trigger" state, the corresponding indicator light is lit through a separate set of contacts of the full-side bypass switch of the platform screen door.

[0010] As a preferred technical solution, the normally open contact of the full-side bypass switch of the platform screen door is connected to the excitation of the platform screen door interlock release relay on the signal system side.

[0011] As a preferred technical solution, if there is no PDQCJ relay on the signal system side, a PDQCJ relay needs to be added separately, where the PDQCJ relay is the platform screen door interlock release relay.

[0012] According to the second aspect of the present invention, an implementation method of a device using the signal system and the platform screen door interlock release is provided, including the following steps:

[0013] Step S101, evaluate the line and current equipment conditions;

[0014] Step S102, add a full-side bypass switch box for the platform screen door on the signal system side, and set the full-side bypass switch and indicator light for each station site on the switch box;

[0015] Step S103, configure the full-side bypass switch circuit for each station site, connect the normally open contact of the full-side bypass switch of the platform screen door to the excitation of the PDQCJ relay on the signal system side, and use a separate set of contacts of the full-side bypass switch of the platform screen door to light the indicator light, where the PDQCJ relay is the platform screen door interlock release relay;

[0016] Step S104, test whether the function of the full-side bypass switch box of the platform screen door meets the expected requirements.

[0017] As a preferred technical solution, the specific content of step S101 includes:

[0018] Whether the interface between the signal system and the platform screen door system has the function of releasing the interlock on the platform screen door side and the interlock release information is independent information. At the same time, confirm whether there is a delay in the interlock release function. If the interlock release function is available and there is a delay, the delay function of the interlock release information needs to be cancelled.

[0019] As a preferred technical solution, the specific content of step S104 includes:

[0020] Step S1041: Test the function of the entire-side bypass switch box of the platform screen door;

[0021] Step S1042: After testing that all switches on the entire-side bypass of the platform screen door are in the "reset" state, the use of the interlock release function on the platform screen door side is not affected.

[0022] As a preferred technical solution, the specific content of step S1041 is as follows:

[0023] When the power supply on the platform screen door side is cut off and the platform screen door system is not started, after placing the entire-side bypass switch of the platform screen door in the "trigger" position, the indicator light shows a red light, the corresponding PDQCJ relay on the signal system side is magnetized and pulled in, the interlocking subsystem collects that PDQCJ is 1, and the ATS subsystem and the MSS subsystem immediately display and record that PDQCJ is in the activated state;

[0024] After the entire-side bypass switch of the platform screen door is placed in the "reset" position, the indicator light goes out, the corresponding PDQCJ relay on the signal system side demagnetizes and drops, the interlocking subsystem collects that PDQCJ is 0, and the ATS subsystem and the MSS subsystem immediately display and record that PDQCJ is in the non-activated state.

[0025] As a preferred technical solution, the specific content of step S1042 is as follows:

[0026] All switches on the entire-side bypass switch box of the platform screen door are in the "reset" state. When performing or canceling the interlock release function on the platform screen door system side, the corresponding PDQCJ relay on the signal system side can be normally pulled in or dropped, the interlocking subsystem collects that PDQCJ is 1 or 0, and the ATS subsystem and the MSS subsystem immediately display and record that PDQCJ is in the activated or non-activated state.

[0027] According to the third aspect of the present invention, an application method of a device using the signal system to release the interlock with the platform screen door is provided, including the following steps:

[0028] Step S201: When a certain platform screen door fails, perform the "interlock release" operation on the platform screen door;

[0029] Step S202: Check the cause of the failure. If the cause of the failure is a platform screen door system failure or a power failure, use the entire-side bypass switch box of the platform screen door; if it is other reasons, troubleshoot the failure through other means;

[0030] Step S203: After confirming the on-site safety conditions and taking safety protection measures, turn the entire-side bypass switch of the platform screen door corresponding to the faulty platform on the switch box to the trigger position. After the entire-side bypass switch of the platform screen door is powered on, the corresponding red indicator light is lit;

[0031] Step S204: Confirm that the interlocking subsystem collects that the PDQCJ relay is 1, and the ATS subsystem and the MSS subsystem display and record that the PDQCJ relay is in the activated state, indicating that the "whole-side platform door bypass" function is effectively executed, and the interlock release function between the signal system and the PSD system is effectively executed, where the PDQCJ relay is the platform door interlock release relay;

[0032] Step S205: Recover the platform door system from the fault;

[0033] Step S206: After confirming that all faults are recovered, restore the whole-side platform door bypass switch to the reset state, and the red indicator light of the switch goes out;

[0034] Step S207: Confirm that the interlocking subsystem collects that the PDQCJ relay is 0, and the ATS subsystem and the MSS subsystem display and record that the PDQCJ relay is in the non-activated state, indicating that the whole-side platform door bypass function has been cancelled.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] 1) Compared with the interface for releasing the interlock between the traditional signal system and the platform door, the "whole-side platform door bypass" switch newly added on the signal system side of the present invention can solve the problem that when there is a fault in the power supply equipment on the platform door side or a fault such as "PSDC dual-system" of the platform door, the interlock release relay on the platform door side cannot be powered on, resulting in the invalidity of the interlock release function between the signal system and the platform door, thereby improving the operation capacity of urban rail transit.

[0037] 2) After the implementation of the present invention, the newly added "whole-side platform door bypass" function on the signal system side can supplement the interlock release function on the platform door side, making the bypass operation between the signal system and the platform door more diverse; at the same time, the indicator light on the "whole-side platform door bypass" switch cabinet can clearly feedback whether the whole-side platform door bypass function is correctly executed, thereby making the interlock release operation simpler and more effective.

[0038] 3) The commonly used interlock release on the platform door side has a limited delay function, and it may be necessary to press the button multiple times in a fault scenario; after the "whole-side platform door bypass" switch is adopted in the present invention, the manual repeated bypass operation can be reduced, and the operation inefficiency caused by untimely operation can be avoided.

[0039] 4) The present invention can be applied to various interfaces between the signal system and the platform door system, including the already opened projects, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figure 1 As shown, a device for releasing the interlock between a signal system and a platform door, the device is connected to the signal system, the device includes a platform door whole side bypass switch box, the platform door whole side bypass switch box is arranged on the signal system side, the platform door whole side bypass switch box includes a platform door whole side bypass switch corresponding to each station site; the platform door whole side bypass relay of the up and down platforms of a station is activated or reset by rotating the platform door whole side bypass switch corresponding to a station.

[0047] The platform door bypass switch is a non-self-resetting switch with a key for rail transit and has two states, namely "trigger" and "reset". The platform door bypass switch is provided with a protective cover. Each platform door bypass switch is associated with an indicator light. When the platform door bypass switch is in the "trigger" state, the corresponding indicator light is lit through a separate set of contacts of the platform door bypass switch.

[0048] By rotating the bypass switch corresponding to a station, the "platform door whole side bypass" relay of the up and down platforms of a station can be activated or reset. When the "platform door whole side bypass" is activated, the corresponding red indicator light is lit through a separate set of contacts of the bypass switch, which can provide feedback on whether the whole side bypass switch is triggered.

[0049] like Figure 2As shown in the figure, the principle of the newly added "whole-side platform screen door bypass" switch in the present invention utilizes the DC24V / DC24V~DC60V power supply at the interface between the signal system and the platform screen door. Through the "whole-side platform screen door bypass" switch and wiring added on the signal system side, it is ensured that when the interlock release failure on the platform screen door side cannot be activated, the signal system still has an effective means to activate the interlock release relay on the signal system side, making it remain energized and performing the interlock release function between the signal system and the platform screen door system.

[0050] In order to reduce the impact on train operation when there is an interlock release failure on the platform screen door side, for projects that have been opened and have a long interlock release delay, the delay function of the existing interlock release button can be cancelled, and at the same time, the above-mentioned "whole-side platform screen door bypass" switch box and corresponding equipment and circuits are newly added. After cancelling the interlock release delay, when using the interlock release on the platform screen door side, in order to ensure that the train can enter and leave the station normally when there is a platform screen door failure, the signal system needs to continuously receive the platform screen door side interlock release input signal that is always at a high level, that is, at this time, the platform or station operator needs to continuously press the interlock release button.

[0051] The present invention solves the problem that the interlock release between the signal system and the platform screen door is invalid due to the platform screen door side failure, affecting the normal operation of the train through the above device.

[0052] Embodiment 2

[0053] The implementation flowchart of the present invention is as Figure 3 shown, and the specific steps include:

[0054] Step S101: Evaluate the line and current equipment conditions. Whether the interface between the signal system and the platform screen door system has the interlock release function on the platform screen door side and the interlock release information is independent information, and at the same time confirm whether there is a delay in the interlock release function. If the interlock release function is available and there is a delay, the delay function of the interlock release information needs to be cancelled.

[0055] Step S102: Add a "whole-side platform screen door bypass" switch box on the signal system side, and set the "whole-side platform screen door bypass" switches and indicator lights for the up and down directions of each station on the box, specifically as Figure 1 shown.

[0056] Step S103: Configure the "whole-side platform screen door bypass" switch circuits for the up and down directions of each station, and the schematic diagram refers to Figure 2Utilize the power supply of the interface between the signal system and the platform screen doors. Connect it to the excitation of the PDQCJ relay (platform screen door interlock release relay) on the signal side through the normally open contact of the "whole-side bypass switch of platform screen doors" to achieve the whole-side bypass function of platform screen doors; use a separate set of contacts of the bypass switch to light up the "whole-side bypass indicator of platform screen doors". For the signal system using PSDC or other platform screen door control systems, when there is no PDQCJ relay on the signal system side, a PDQCJ relay needs to be added separately.

[0057] Step S104: Test whether the function of the "whole-side bypass switch box of platform screen doors" meets the expected requirements, specifically as follows:

[0058] 1) Test the function of the "whole-side bypass switch box of platform screen doors". When the power supply on the platform screen door side is cut off and the platform screen door system is not started, after placing the "upward" or "downward" switch of the "whole-side bypass of platform screen doors" in the "trigger" position, the bypass switch indicator shows a red light, the corresponding upward or downward PDQCJ relay on the signal side is excited and pulled in, the interlocking subsystem collects that PDQCJ is 1, and the ATS subsystem and the MSS subsystem immediately display and record that PDQCJ is in the activated state; after placing the "upward" or "downward" switch of the "whole-side bypass of platform screen doors" in the "reset" position, the bypass switch indicator shows a turned-off light, the corresponding upward or downward PDQCJ relay on the signal side loses excitation and drops, the interlocking subsystem collects that PDQCJ is 0, and the ATS subsystem and the MSS subsystem immediately display and record that PDQCJ is in the non-activated state.

[0059] 2) Test that after all switches on the "whole-side bypass of platform screen doors" are in the "reset" state, it does not affect the use of the interlock release function on the platform screen door side. When all switches on the "whole-side bypass switch box of platform screen doors" are in the "reset" state, perform or cancel the interlock release function on the platform screen door system side, the corresponding upward or downward PDQCJ relay on the signal side can be normally pulled in or dropped, the interlocking subsystem collects that PDQCJ is 1 or 0, and the ATS subsystem and the MSS subsystem immediately display and record that PDQCJ is in the activated or non-activated state.

[0060] After the implementation of the present invention, the newly added "whole-side bypass function of platform screen doors" on the signal system side can supplement the interlock release function on the platform screen door side (specifically, refer to Table 1), making the bypass operation between the signal system and the platform screen doors more diverse. At the same time, the indicator light on the "whole-side bypass switch box of platform screen doors" can clearly feedback whether the whole-side bypass function of platform screen doors is correctly executed, thus making the interlock release operation simpler and more effective.

[0063] Embodiment 3

[0064] The operation and use process of the present invention is asFigure 4 As shown in the figure, the specific steps are as follows (the usage process can be adjusted according to the actual situation of each line in actual use. The relevant safety confirmation and operation process before handling the unlocking of the platform screen door interlock and after the signal system has executed the unlocking command shall be formulated by each line):

[0065] Step S201: When a platform screen door fails, the operator handles the "unlocking of the interlock" operation of the platform screen door. After the "unlocking of the interlock" of the platform screen door is implemented, the signal system can never receive the unlocking activation information from the platform screen door system.

[0066] Step S202: The operator checks the cause of the failure. If the cause of the failure is a platform screen door system failure or a power failure, the "whole-side bypass switch of the platform screen door" switch cabinet can be used; if it is for other reasons, other means need to be used to eliminate the failure.

[0067] Step S203: After the operating personnel confirm the on-site safety conditions and take safety protection measures, the operator turns the "whole-side bypass switch of the platform screen door" of the corresponding faulty platform on the switch cabinet to the "trigger" position (to prevent misoperation, one person can execute it and another person can conduct a secondary confirmation). After the "whole-side bypass switch of the platform screen door" is powered on, the corresponding red indicator light lights up.

[0068] Step S204: Confirm that the interlocking subsystem collects PDQCJ as 1, and the ATS subsystem and the MSS subsystem display and record that PDQCJ is in the activated state, indicating that the "whole-side bypass function of the platform screen door" is executed effectively. The unlocking function between the signal system and the PSD system is executed effectively.

[0069] Step S205: The on-site platform screen door system failure is restored in a timely manner.

[0070] Step S206: After the operating personnel confirm that all failures have been restored, the operating personnel restore the "whole-side bypass switch of the platform screen door" to the "reset" state, and the red indicator light of the switch goes out.

[0071] Step S207: Confirm that the interlocking subsystem collects PDQCJ as 0, and the ATS subsystem and the MSS subsystem display and record that PDQCJ is in the non-activated state, indicating that the whole-side bypass function of the platform screen door has been cancelled.

[0072] Compared with the interface for releasing the interlock between the traditional signal system and the platform screen door, a platform screen door bypass button box is set in the signal equipment room. On the platform screen door bypass button box, "platform screen door full-side bypass" switches and indicator lights for each platform are set to operate the "platform screen door full-side bypass" switches. At the same time, whether the bypass is correctly executed can be fed back through the indicator lights on the switch box. By connecting the normally open contacts of the "platform screen door full-side bypass" switch relay on the signal side to the excitation point of the PSDCJ relay on the signal side, the function of the platform screen door full-side bypass is realized, which can solve the problem that when there are faults in the power supply equipment on the platform screen door side or faults such as "PSDC dual-system" of the platform screen door, the interlock release relay on the PSD side cannot be energized, resulting in the invalidity of the interlock release function between the signal system and the platform screen door, thereby improving the operation capacity of urban rail transit.

[0073] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention.
