Description

Technical Field

[0001] This invention relates to the field of civil defense doors for urban rail transit subways, and more specifically to a method and system for abnormal linkage protection of civil defense doors in subway sections. Background Technology

[0002] Subway tunnel civil defense doors are doors installed in subway tunnels for use as entrances and exits for civil defense protection projects. In the event of natural disasters such as war or earthquakes, these doors provide protection at the entrance of the subway tunnel area.

[0003] When trains are running at high speeds, the piston wind pressure on the air-raid shelter doors in the section is relatively large. Therefore, it is essential to ensure that the air-raid shelter equipment is securely fixed and does not intrude into the clearance. However, due to equipment malfunctions or other reasons, the air-raid shelter doors may vibrate or shift, posing a danger to the operation of subway trains and potentially causing vehicle damage and personal injury.

[0004] In existing technologies, to prevent the air-raid shelter doors in subway sections from loosening and encroaching on the clearance gauge, thus posing a danger to the operation of subway trains, it is necessary to monitor the status of the air-raid shelter doors in subway sections. Currently, the monitoring of air-raid shelter doors in subway sections mainly involves the following two situations:

[0005] 1. If the air-raid shelter door system is not equipped with monitoring devices, the subway operating company will arrange maintenance personnel to inspect it regularly according to operating regulations. If any displacement of the air-raid shelter door is found, it will be manually reported to the dispatch center for handling. However, this manual inspection increases labor intensity and is prone to errors.

[0006] 2. If a monitoring device is installed on the air-raid shelter door system, the system will send abnormal alarm information to the integrated monitoring system. If an abnormality occurs in the air-raid shelter door, an alarm prompt will be issued on the integrated monitoring system terminal. Maintenance personnel will need to access the camera or go to the site to confirm the status of the air-raid shelter door. Simultaneously, monitoring personnel will control the corresponding train to stop operation based on the alarm prompt to prevent safety accidents. This system relies on personnel transmitting information and manually setting protection, which is highly prone to errors, posing a danger to the operation of subway trains, leading to vehicle damage and personal injury. Summary of the Invention

[0007] In order to overcome the defects in the existing technology, the present invention discloses a method and system for abnormal linkage protection of civil defense doors in subway sections. The purpose of the present invention is to solve the problem that when the monitoring device is installed in the prior art, the information is transmitted by personnel and the protection is set manually, which is very easy to make mistakes, endangering the operation of subway trains, causing vehicle damage and casualties. In this invention, the signaling system sets up a protective signal upstream of the blast door (when the blast door is close to the platform, the platform exit signal can also serve as the blast door protective signal); the locations of blast doors in the section are included in the CC (Carbone Controller) electronic map management; the signaling system obtains the status of the blast doors through the ATS (Automatic Train Supervision) and integrated monitoring interface; when a blast door alarms abnormally, the train dispatching terminal provides an alarm prompt and automatically pushes the blast door monitoring camera image to the large screen to remind relevant personnel; at the same time, the signal ATS subsystem sends linkage information to the CI (Computer Interlocking) subsystem, and the CI subsystem blocks the exit signal and / or the blast door protective signal of the previous station in the section with the abnormal blast door to ensure that the platform train does not enter the abnormal section; in addition, the onboard CC establishes an ATP (Automatic Train Protection) safety protection point to protect the train and prohibit the train from passing through the blast door safety protection point to prevent safety accidents. This invention enables the system to automatically activate when an anomaly is detected at the civil defense door in the section, reducing errors caused by personnel transmitting information and manually setting protection. It ensures safe train operation by automatically blocking the exit signal and / or the civil defense door protection signal and establishing safety protection points, thereby improving the automation and intelligence of the system.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] A method for abnormal linkage protection of civil defense doors in subway sections includes monitoring and display steps, abnormal judgment steps, abnormal alarm steps, signal blocking steps, protection point establishment steps, and restoration of normal operation steps.

[0010] The monitoring and display steps involve the integrated monitoring subsystem monitoring the information of the civil defense doors in each subway section in real time, and sending the monitored civil defense door information to the signal ATS subsystem. The signal ATS subsystem then sends the monitored civil defense door information to the train dispatching terminal, and the train dispatching terminal displays the monitored civil defense door information in real time.

[0011] The anomaly judgment step involves the integrated monitoring subsystem judging whether each civil defense door is abnormal when monitoring the civil defense doors in each subway section. When a civil defense door is abnormal, the corresponding civil defense door abnormality information is sent to the signal ATS subsystem.

[0012] In the abnormal alarm step, after the signal ATS subsystem receives the abnormal information of the air defense door, it sends the abnormal information of the air defense door to the train dispatch terminal, and the train dispatch terminal gives the abnormal alarm prompt of the air defense door.

[0013] In the signal blocking step, after the signal ATS subsystem receives the abnormal information of the air defense door, it sends the linkage information to the CI subsystem, and the CI subsystem automatically links the exit signal and / or the air defense door protection signal to block and protect it.

[0014] The protection point establishment step involves the signal ATS subsystem receiving abnormal information about the air defense door, generating a protection point establishment request, and sending the request to the CC subsystem. The CC subsystem then establishes an ATP safety protection point based on the request and the specific location of the train in the electronic map to provide safety protection for the train.

[0015] The steps for restoring normal operation are as follows: after the integrated monitoring subsystem monitors the air defense door to normal, the train dispatching terminal cancels the abnormal alarm of the air defense door, the signal ATS subsystem sends a message to the CI subsystem to cancel the blocking protection of the exit signal and / or the air defense door protection signal, and sends a message to the CC subsystem to cancel the establishment of the safety protection point.

[0016] In the above method, the integrated monitoring subsystem monitors the information of the air-raid shelter doors in each subway section in real time, and the train dispatching terminal displays the monitored air-raid shelter door information in real time so that staff can understand it in real time. When monitoring, the integrated monitoring subsystem determines whether each air-raid shelter door is abnormal. When an abnormality is detected, the train dispatching terminal issues an air-raid shelter door abnormality alarm prompt to remind relevant staff; at the same time, for trains that have not departed from the previous station in the section with abnormal air-raid shelter doors or trains that have not entered the air-raid shelter area upstream of the air-raid shelter door, the signal ATS subsystem, in conjunction with the CI subsystem, automatically closes the departure signal and / or the air-raid shelter door protection signal to ensure that trains on the platform or trains upstream of the air-raid shelter door do not enter the section with abnormal air-raid shelter doors, which facilitates operational adjustments; in addition, the CC subsystem establishes safety protection points based on the specific location of the train in the electronic map and the relative position of the air-raid shelter door to provide safety protection for the train and prevent safety accidents from occurring.

[0017] Preferably, in the step of establishing the protection point, the CC subsystem judges the trains within the agreed range of the abnormal protection point. If the train has entered or is approaching the protection point, it triggers emergency braking at the current position and initiates corresponding rescue measures.

[0018] For trains that are far from the abnormal protection point but are heading towards it, the onboard control (CC) will retract the movement authorization to the boundary of the protection point and automatically set a speed limit for the train based on the distance of the movement authorization, ensuring that the train approaches the authorized end point at a low speed and controls the train to trigger the service brake to stop in front of the civil defense door protection point.

[0019] The above methods, through the two control methods described above, control the corresponding trains to stop, ensuring safe train operation and preventing safety accidents.

[0020] Preferably, in the abnormal alarm step, at the train dispatching terminal, the dispatcher confirms the actual status of the air-raid shelter door through a camera. When it is confirmed that the abnormal air-raid shelter door is a false alarm, the abnormal air-raid shelter door information in the bypass section is released, the blocking status of the exit signal and / or the air-raid shelter door protection signal of the previous station platform is canceled, the establishment of safety protection points and speed limits in the CC subsystem is canceled, and the train resumes normal operation.

[0021] In the above method, after the signal ATS subsystem receives an abnormal signal from the air-raid shelter door in the section, if the train dispatching terminal manually confirms that the abnormal air-raid shelter door is a false alarm, it can bypass the abnormal air-raid shelter door information in the section, cancel the blocking status of the exit signal and / or the air-raid shelter door protection signal of the previous station platform, and cancel the establishment of the safety protection point by the CC subsystem. This can reduce the impact of false alarms on normal operation.

[0022] Preferably, in the protection point establishment step, the CC subsystem responds to the protection point establishment request sent by the signal ATS subsystem. The signal ATS subsystem queries the protection list of the air-raid shelter doors in the electronic map based on the abnormal information of the air-raid shelter doors in the section, obtains the location corresponding to the abnormal air-raid shelter door, and confirms that the location is not in a protected state. The CC subsystem responds to the protection point establishment request message sent by the signal ATS subsystem and uses the location of the air-raid shelter door in the electronic map as the ATP security protection point established by the CC subsystem.

[0023] After the CC subsystem establishes the ATP security protection point, the information in the section air defense door protection list is set to the protected status, and the protected information of the air defense door is sent to the signal ATS subsystem, which then displays the air defense door protection icon.

[0024] Preferably, the signal ATS subsystem responds to abnormal information about the air defense door in the section and generates a prompt message. The prompt message includes whether to send a prompt to the CI subsystem to block the exit signal of the previous station platform and / or the air defense door protection signal, and whether to send a prompt to the onboard CC to request the establishment of a protection point.

[0025] Preferably, for trains downstream of the air-raid shelter and departing from the shelter, the CC subsystem controls the train to run normally until it stops at the next station.

[0026] Preferably, in the step of restoring normal operation, the CC subsystem responds to the request to cancel the ATP safety protection point sent by the signal ATS subsystem; after the signal ATS subsystem receives confirmation that the air defense door in the section has returned to normal and the train dispatch terminal has manually confirmed that the air defense door has returned to normal, the signal ATS subsystem obtains the corresponding air defense door protection point based on the air defense door's return to normal information; the request to cancel the ATP safety protection point is generated by the signal ATS subsystem in response to the air defense door's normal status information in the section.

[0027] The CC subsystem checks the list of protected air defense doors in the electronic map to confirm that the air defense door is in a protected state, and then returns a confirmation message to the signal ATS subsystem.

[0028] In the above method, the CC subsystem will verify the correctness of the ATS subsystem's cancellation command to avoid system errors in canceling protection points.

[0029] Preferably, in the step of restoring normal operation, the CC subsystem responds to the confirmation message sent by the signal ATS subsystem and cancels the protection point corresponding to the air defense door;

[0030] After the CC subsystem cancels the ATP safety protection point, the protection information in the section's civil defense door protection list is set to an unprotected state, and the information to restore the civil defense door safety protection point to normal is sent to the signal ATS subsystem, which then displays the civil defense door protection icon. After the signal ATS subsystem cancels the protection point, the CI subsystem cancels the blockage of the previous station's exit signal and / or the civil defense door protection signal in the section according to the ATS subsystem's cancellation command.

[0031] In the above method, the CC subsystem automatically cancels the ATP safety protection point and informs the ATS subsystem that the civil defense door protection point in the section has been set to an unprotected state. The train dispatching terminal provides a prompt that the civil defense door has been restored to normal, reminding relevant personnel to organize train operations normally. At the same time, the CI subsystem cancels the blockage of the exit signal and / or the civil defense door protection signal of the previous station in the civil defense door section. After both the ATP safety protection point and the signal are restored, the train regains its movement authorization and resumes normal operation based on the authorization command.

[0032] Based on the above-mentioned method for abnormal linkage protection of civil defense doors in subway sections, the present invention also provides a system for abnormal linkage protection of civil defense doors in subway sections, comprising:

[0033] Train departure signals are installed inside subway platforms to guide trains out of the station.

[0034] The air defense door protection signal is installed upstream of the air defense door to guide trains into the air defense door area;

[0035] The integrated monitoring subsystem monitors the information of air-raid shelter doors in each subway section in real time;

[0036] The signal ATS subsystem is communicatively connected to the integrated monitoring subsystem. In response to the abnormal alarm information of the air defense door in the interval, it obtains the abnormal interval of the air defense door from the integrated monitoring subsystem and generates a protection point establishment request and a protection signal blockage command.

[0037] The CC subsystem is communicatively connected to the signal ATS subsystem, receives protection point establishment requests sent by the signal ATS subsystem, and establishes ATP safety protection points to protect the train according to the requests.

[0038] The CI subsystem is communicatively connected to the train departure signal, the air-raid shelter protection signal, and the signal ATS subsystem. According to the blocking command of the protection signal of the signal ATS subsystem, it will lock and protect the train departure signal and / or the air-raid shelter protection signal in a coordinated manner to ensure that the platform train does not enter the abnormal zone.

[0039] The train dispatch terminal communicates with the signal ATS subsystem, displays the monitored information of the air defense doors in real time, and provides an alarm when an air defense door malfunctions.

[0040] Preferably, the CC subsystem determines the train within the protection point range. If the train has entered or is approaching the protection point range, it triggers emergency braking at the current position. If the train is far from the protection point and is heading towards it, the onboard CC will retract its movement authorization to the boundary of the protection point and automatically set a speed limit on the train according to the distance of the movement authorization, ensuring that the train approaches the authorized end point at a low speed and controls the train to trigger service braking to stop in front of the air defense door protection point.

[0041] In this invention, the signaling system sets up a protective signal upstream of the air-raid shelter door (when the air-raid shelter door is close to the platform, the platform exit signal can also serve as the air-raid shelter door protective signal); the locations of air-raid shelter doors in the section are included in the CC electronic map management. The dispatcher manually confirms the actual status of the air-raid shelter door. If the abnormality of the air-raid shelter door is confirmed as a false alarm, the ATS subsystem can bypass the abnormal information of the air-raid shelter door in the section, the CI subsystem cancels the blocking status of the previous station's platform exit signal and / or the air-raid shelter door protective signal, and the CC subsystem cancels the establishment of safety protection points and speed limits, allowing the train to resume normal operation.

[0042] The beneficial effects of this invention are:

[0043] The present invention provides a method for the linkage protection of abnormal civil defense doors in subway sections. The integrated monitoring subsystem monitors the information of civil defense doors in each subway section in real time, and the train dispatching terminal displays the monitored information in real time for staff to understand. During monitoring, the integrated monitoring subsystem determines whether each civil defense door is abnormal. If an abnormality is detected, the train dispatching terminal issues an alarm to alert relevant staff. Simultaneously, the signal ATS subsystem, in conjunction with the CI subsystem, blocks the exit signal and / or the civil defense door protection signal at the station above the abnormal civil defense door section, ensuring that trains do not enter the abnormal section. In addition, the onboard CC establishes an ATP safety protection point to protect the train and limit its speed, preventing accidents.

[0044] Compared with existing technologies, this invention offers higher automation, balancing operational efficiency with improved driving safety. This invention is applicable to urban rail transit, and is particularly suitable for fully automated, driverless lines. Attached Figure Description

[0045] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0046] The following will provide a clear and complete description of the concept, specific structure, and technical effects of the present invention in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention.

[0047] Example 1

[0048] A method for abnormal linkage protection of air-raid shelter doors in subway sections includes the following steps:

[0049] S1. The integrated monitoring subsystem monitors the information of the civil defense doors in each subway section in real time and sends the monitored information to the signal ATS subsystem. The signal ATS subsystem then sends the monitored information to the train dispatching terminal, which displays the monitored information of the civil defense doors in real time.

[0050] S2. When monitoring the air defense doors in each subway section, the integrated monitoring subsystem determines whether each air defense door is abnormal. When an air defense door is abnormal, the corresponding air defense door abnormality information is sent to the signal ATS subsystem.

[0051] S3. After receiving the abnormal information of the air defense door, the signal ATS subsystem sends the abnormal information of the air defense door to the train dispatch terminal, and the train dispatch terminal gives the air defense door abnormal alarm prompt.

[0052] S4. After receiving abnormal information from the air-raid shelter door, the signal ATS subsystem will send the linkage information to the CI subsystem. The CI subsystem will automatically link the exit signal and / or the air-raid shelter door protection signal to block and protect the door.

[0053] After receiving abnormal information about the civil defense door, the S5 and ATS subsystems generate a protection point establishment request and send the request to the CC subsystem. The CC subsystem establishes an ATP safety protection point to protect the train based on the request and the specific location of the train in the electronic map.

[0054] S6. After the integrated monitoring subsystem restores the civil defense door to normal, the train dispatching terminal cancels the abnormal alarm of the civil defense door. The signal ATS subsystem sends a message to the CI subsystem to cancel the blocking protection of the exit signal and / or the civil defense door protection signal, and sends a message to the CC subsystem to cancel the establishment of the safety protection point.

[0055] In this embodiment, as Figure 1 As shown, the integrated monitoring subsystem monitors the information of air-raid shelter doors in each subway section in real time, and the train dispatching terminal displays the monitored air-raid shelter door information in real time for staff to understand. During monitoring, the integrated monitoring subsystem determines whether each air-raid shelter door is abnormal. If an abnormality is detected, the train dispatching terminal issues an air-raid shelter door abnormality alarm to remind relevant staff. Simultaneously, for trains that have not yet departed from the previous station in the section with the abnormal air-raid shelter door, or trains upstream of the air-raid shelter door that have not entered the air-raid shelter area, the signal ATS subsystem, in conjunction with the CI subsystem, automatically closes the departure signal and / or the air-raid shelter door protection signal to ensure that trains on the platform or upstream of the air-raid shelter door do not enter the section with the abnormal air-raid shelter door, facilitating operational adjustments. In addition, the CC subsystem establishes safety protection points based on the specific location of the train in the electronic map and the relative position of the air-raid shelter door to provide safety protection for the train and prevent safety accidents.

[0056] Example 2

[0057] This embodiment further elaborates on step S3 based on embodiment 1. In step S3, at the train dispatching terminal, the dispatcher confirms the actual status of the air-raid shelter door through a camera. When it is confirmed that the air-raid shelter door malfunction is a false alarm, the abnormal air-raid shelter door information in the bypass section is released, the blocking status of the exit signal and / or the air-raid shelter door protection signal of the previous station platform is canceled, the establishment of safety protection points and speed limits in the CC subsystem is canceled, and the train resumes normal operation.

[0058] In the above method, after the signal ATS subsystem receives an abnormal signal from the air-raid shelter door in the section, if the train dispatching terminal manually confirms that the abnormal air-raid shelter door is a false alarm, it can bypass the abnormal air-raid shelter door information in the section, cancel the blocking status of the exit signal and / or the air-raid shelter door protection signal of the previous station platform, and cancel the establishment of the safety protection point by the CC subsystem. This can reduce the impact of false alarms on normal operation.

[0059] Example 3

[0060] This embodiment further elaborates on step S5 based on embodiment 2. In step S5, the CC subsystem judges the train within the agreed range of the abnormal protection point. If the train has entered or is close to the protection point, it triggers emergency braking at the current position and initiates corresponding rescue measures.

[0061] For trains that are far from the abnormal protection point but are heading towards it, the onboard control (CC) will retract the movement authorization to the boundary of the protection point and automatically set a speed limit for the train based on the distance of the movement authorization, ensuring that the train approaches the authorized end point at a low speed and controls the train to trigger the service brake to stop in front of the civil defense door protection point.

[0062] As an optimized solution in this embodiment, in step S5, the CC subsystem responds to the protection point establishment request sent by the signal ATS subsystem. The signal ATS subsystem queries the protection list of the air defense doors in the electronic map based on the abnormal information of the air defense doors in the section, obtains the location corresponding to the abnormal air defense door, and confirms that the location is not in a protected state. The CC subsystem responds to the protection point establishment request message sent by the signal ATS subsystem and uses the location of the air defense door in the electronic map as the ATP security protection point established by the CC subsystem.

[0063] After the CC subsystem establishes the ATP security protection point, the information in the section air defense door protection list is set to the protected status, and the protected information of the air defense door is sent to the signal ATS subsystem, which then displays the air defense door protection icon.

[0064] As an optimization of this embodiment, the signal ATS subsystem responds to the abnormal information of the air defense door in the section and generates a prompt message. The prompt message includes whether to send a prompt to the CI subsystem to block the exit signal of the previous station platform and / or the air defense door protection signal, and whether to send a prompt to the on-board CC to request the establishment of a protection point.

[0065] As an optimization of this embodiment, for trains downstream of the air-raid shelter and departing from the shelter, the CC subsystem controls the train to run normally until it stops at the next station.

[0066] Example 4

[0067] This embodiment further elaborates on step S6 based on embodiment 3. In step S6, the CC subsystem responds to the request to cancel the ATP safety protection point sent by the signal ATS subsystem; after the signal ATS subsystem receives confirmation that the air defense door in the section has returned to normal and the train dispatch terminal has manually confirmed that the air defense door has returned to normal, the signal ATS subsystem obtains the corresponding air defense door protection point based on the air defense door return to normal information; the request to cancel the ATP safety protection point is generated by the signal ATS subsystem in response to the air defense door normal status information in the section.

[0068] The CC subsystem checks the list of protected air defense doors in the electronic map to confirm that the air defense door is in a protected state, and then returns a confirmation message to the signal ATS subsystem.

[0069] As an optimization of this embodiment, in step S6, the CC subsystem responds to the confirmation message sent by the signal ATS subsystem and cancels the protection point corresponding to the air defense door;

[0070] After the CC subsystem cancels the ATP safety protection point, the protection information in the section's civil defense door protection list is set to an unprotected state, and the information to restore the civil defense door safety protection point to normal is sent to the signal ATS subsystem, which then displays the civil defense door protection icon. After the signal ATS subsystem cancels the protection point, the CI subsystem cancels the blockage of the previous station's exit signal and / or the civil defense door protection signal in the section according to the ATS subsystem's cancellation command.

[0071] In the above method, the CC subsystem automatically cancels the ATP safety protection point and informs the ATS subsystem that the civil defense door protection point in the section has been set to an unprotected state. The train dispatching terminal provides a prompt that the civil defense door has been restored to normal, reminding relevant personnel to organize train operations normally. At the same time, the CI subsystem cancels the blockage of the exit signal and / or the civil defense door protection signal of the previous station in the civil defense door section. After both the ATP safety protection point and the signal are restored, the train regains its movement authorization and resumes normal operation based on the authorization command.

In response to the abnormal alarm information of the air defense door in the interval, it obtains the abnormal interval of the air defense door from the integrated monitoring subsystem and generates a protection point establishment request and a protection signal blockage command.

[0078] The CC subsystem is communicatively connected to the signal ATS subsystem. It receives protection point establishment requests sent by the signal ATS subsystem and establishes ATP safety protection points to protect the train according to the requests. The CC subsystem judges the train within the protection point range. If the train has entered or is approaching the protection point range, it triggers emergency braking at the current position. If the train is far from the protection point and is heading towards it, the onboard CC will retract the movement authorization to the boundary of the protection point and automatically set a speed limit for the train according to the movement authorization distance to ensure that the train approaches the authorized end point at a low speed and controls the train to stop by triggering service braking in front of the civil defense door protection point.

[0079] The CI subsystem is communicatively connected to the train departure signal, the air-raid shelter protection signal, and the signal ATS subsystem. According to the blocking command of the protection signal of the signal ATS subsystem, it will lock and protect the train departure signal and / or the air-raid shelter protection signal in a coordinated manner to ensure that the platform train does not enter the abnormal zone.

[0080] The train dispatch terminal communicates with the signal ATS subsystem, displays the monitored information of the air defense doors in real time, and provides an alarm when an air defense door malfunctions.

[0081] In this embodiment, the signaling system sets up a protective signal upstream of the air-raid shelter door (when the air-raid shelter door is close to the platform, the platform exit signal can also serve as the air-raid shelter door protective signal); the locations of air-raid shelter doors in the section are included in the CC electronic map management. When the dispatcher manually confirms that the air-raid shelter door abnormality is a false alarm, the ATS subsystem can bypass the air-raid shelter door abnormality information in the section, the CI subsystem cancels the blocking status of the previous station's platform exit signal and / or air-raid shelter door protective signal, and the CC subsystem cancels the establishment of safety protection points and speed limits, allowing the train to resume normal operation.
