Description

Technical Field

[0001] The present invention relates to the technical field of intelligent fault processing, and in particular to a platform door fault emergency processing analysis method and system. Background Art

[0002] The platform door system is installed at the edge of the platform of the station along the urban rail transit line, isolating the platform waiting area from the track running area, and corresponds to the train door. It is an electromechanical equipment system. The application of platform doors isolates passengers from the track and train, improves the operational safety factor, improves the platform environment for passengers to wait for the train, and also helps to save operating costs and construction costs. The opening and closing of the platform door is generally carried out in conjunction with the movement of the train door when the train arrives at the station, providing passengers with a passage to get on and off the train.

[0003] Once the platform door system fails, it may cause the train to be unable to enter and exit the station normally. At this time, emergency measures need to be taken by the driver, station staff and dispatcher to ensure the normal realization of the train entry and exit functions under the premise of ensuring safety. When a common single sliding door failure occurs on site, emergency measures can be completed by isolating the faulty sliding door, which generally does not affect the driving. However, when multiple or one side of the sliding door fails on site, due to the extremely low frequency of failures and the lack of a fault analysis system for emergency response personnel, emergency response personnel can only report information and operate step by step according to the process corresponding to the fault phenomenon. In more serious cases, due to nervousness, they may even remember the wrong process or make mistakes in operation, which often causes train delays.

[0004] In view of the above-mentioned technical problems, it is very necessary to provide a platform door fault analysis system and method for assisting on-site emergency response personnel in emergency response.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0006] The purpose of the present invention is to address the deficiencies of the prior art and thereby provide a platform door failure emergency handling analysis method and system, thereby improving the efficiency of on-site emergency handling.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is: a platform door failure emergency disposal analysis method, comprising the following steps:

[0008] Screen out the fault phenomena that can be identified and need emergency treatment, analyze the existing platform door fault emergency treatment process corresponding to each fault phenomenon, and find out the key nodes of the process; determine whether the status of each key node of the process can be monitored by the platform door system one by one. If it cannot be monitored by the platform door system, set a status measurement point at the current key node of the process, monitor the current status measurement point through the status monitoring module, and obtain the status monitoring data of the status measurement point;

[0009] According to the principle that the status of key nodes of the process is known, the existing platform door fault emergency response process corresponding to each fault phenomenon is decomposed into multiple emergency response models based on the fault cause. Each emergency response model corresponds to at least one fault cause, including the minimum emergency response process executed when solving the fault cause.

[0010] Assign a trigger mode to each emergency response model according to the trigger source type of the fault cause, wherein the trigger mode includes an abnormal state monitoring data trigger mode, an abnormal operation state data trigger mode and an abnormal fault state data trigger mode; different trigger modes are assigned different priorities according to the logical relationship between the fault causes;

[0011] Obtain the status monitoring data of the status monitoring module and the status monitoring data, operation status data and fault status data of the platform door system and analyze them to determine the appropriate triggering mode and fault cause;

[0012] The emergency response model is determined according to the matching trigger method and the cause of the fault. When there is only one emergency response model, the relevant personnel are notified to execute the emergency response model. When there are multiple emergency response models, the multiple emergency response models are sorted in order of trigger method priority from high to low, and the relevant personnel are notified to execute the emergency response model corresponding to the high-priority trigger method. Based on the status monitoring data, fault status data and operation status data of the platform door system acquired again, analyze whether the currently executed emergency response model is valid. If it is valid, the relevant personnel are notified to keep executing the current emergency response model. If it is invalid, the relevant personnel are notified to execute the emergency response model corresponding to the low-priority trigger method.

[0013] Based on the above, the status monitoring data of the status monitoring module and the status monitoring data, operation status data and fault status data of the platform door system are obtained and analyzed, and when the triggering mode that meets the requirements is determined, the following steps are performed:

[0014] Periodically obtain the status monitoring data of the status monitoring module and the status monitoring data and operation status data of the platform door system;

[0015] After receiving the status monitoring data, determine whether there is abnormal status monitoring data. If there is abnormal status monitoring data, determine that it meets the abnormal status monitoring data triggering mode, and analyze the periodically acquired status monitoring data and operation status data to determine the cause of the fault;

[0016] After receiving the operation status data, determine whether there is abnormal operation status data. If there is abnormal operation status data, determine that it meets the abnormal operation status data trigger mode, and analyze based on the periodically acquired status monitoring data and operation status data to determine the cause of the fault;

[0017] When the fault status data uploaded by the platform door system is received, it is determined that it meets the abnormal fault status data trigger mode, and based on the fault status data, the periodically acquired status monitoring data and the operating status data, analysis is performed to determine the cause of the fault.

[0018] The present invention also provides a platform door fault emergency disposal analysis system, the platform door system is used to complete corresponding actions according to the control commands of the server and the on-site emergency disposal personnel, and upload fault status data to the server when a fault occurs, and periodically monitor the fault status of the platform door.

[0019] The status monitoring module is connected to the platform door system, and is used to periodically read the operation record data and status monitoring data in the platform door system and upload them to the server, and periodically upload its own status monitoring data to the server, wherein the key nodes of the process are found by analyzing the existing platform door fault emergency handling process corresponding to the fault phenomenon that can be identified and needs emergency handling, and corresponding status measurement points are added to the key nodes of the process to form key measurement points, and it is judged one by one whether the status of each key node of the process can be monitored by the platform door system. If it cannot be monitored by the platform door system, a status measurement point is set at the current key node of the process, and the current status measurement point is monitored by the status monitoring module to obtain the status monitoring data of the status measurement point;

[0020] The server has built-in multiple emergency response models for fault phenomena that can be identified and require emergency response, each emergency response model corresponds to at least one fault cause, including a minimum emergency processing flow executed when solving the fault cause, and each emergency response model is assigned a corresponding trigger mode according to the trigger source type of the fault cause, the trigger mode includes an abnormal state monitoring data trigger mode, an abnormal operation state data trigger mode and an abnormal fault state data trigger mode, wherein different trigger modes are assigned different priorities according to the logical relationship between the fault causes;

[0021] The server obtains the status monitoring data of the status monitoring module and the status monitoring data, operation status data and fault status data of the platform door system, and performs analysis to determine the matching trigger mode and fault cause; determines the emergency response model according to the matching trigger mode and fault cause, and when there is only one emergency response model, notifies the relevant post personnel to execute the emergency response model through the display terminal; when there are multiple emergency response models, sorts the multiple emergency response models in order of trigger mode priority from high to low, and notifies the relevant post personnel to execute the emergency response model corresponding to the high-priority trigger mode through the display terminal, and analyzes whether the currently executed emergency response model is valid based on the status monitoring data, fault status data and operation status data of the platform door system acquired again. If it is valid, notify the relevant post personnel through the display terminal to keep executing the current emergency response model; if it is invalid, notify the relevant post personnel through the display terminal to execute the emergency response model corresponding to the low-priority trigger mode.

[0022] Compared with the prior art, the present invention has outstanding substantive features and significant progress. Specifically, the original emergency response model set according to the fault phenomenon is decomposed into multiple emergency response models set according to the fault cause. The system automatically completes the emergency response model matching, which effectively reduces unnecessary operation links, improves the on-site emergency response efficiency, and reduces the possibility of train delays caused by platform door failures. It has strong generalizability. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0030] like Figure 1 As shown, a platform door failure emergency treatment analysis method includes the following steps:

[0031] Screen out the fault phenomena that can be identified and need emergency treatment, analyze the existing platform door fault emergency treatment process corresponding to each fault phenomenon, and find out the key nodes of the process; determine whether the status of each key node of the process can be monitored by the platform door system one by one. If it cannot be monitored by the platform door system, set a status measurement point at the current key node of the process, monitor the current status measurement point through the status monitoring module, and obtain the status monitoring data of the status measurement point;

[0032] According to the principle that the status of key nodes of the process is known, the existing platform door fault emergency response process corresponding to each fault phenomenon is decomposed into multiple emergency response models based on the fault cause. Each emergency response model corresponds to at least one fault cause, including the minimum emergency response process executed when solving the fault cause.

[0033] A trigger mode is assigned to each emergency response model according to the trigger source type of the fault cause, wherein the trigger source type includes abnormal state monitoring data, abnormal operation state data and abnormal fault state data; the trigger mode includes abnormal state monitoring data trigger mode, abnormal operation state data trigger mode and abnormal fault state data trigger mode; different trigger modes are assigned different priorities according to the logical relationship between the fault causes;

[0034] Obtain the status monitoring data of the status monitoring module and the status monitoring data, operation status data and fault status data of the platform door system and analyze them to determine the appropriate triggering mode and fault cause;

[0035] The emergency response model is determined according to the matching trigger method and the cause of the fault. When there is only one emergency response model, the relevant personnel are notified to execute the emergency response model. When there are multiple emergency response models, the multiple emergency response models are sorted in order of trigger method priority from high to low, and the relevant personnel are notified to execute the emergency response model corresponding to the high-priority trigger method. Based on the status monitoring data, fault status data and operation status data of the platform door system acquired again, analyze whether the currently executed emergency response model is valid. If it is valid, the relevant personnel are notified to keep executing the current emergency response model. If it is invalid, the relevant personnel are notified to execute the emergency response model corresponding to the low-priority trigger method.

[0036] It can be understood that the selection of the emergency response model is based on the control logic of the platform door system. When a certain fault cause leads to multiple fault status data and multiple abnormal key measurement point status monitoring data, the priority is set so that only the emergency response process corresponding to the current fault cause is displayed in the end.

[0037] Furthermore, since the setting of the emergency response model depends on the minimum emergency response process corresponding to the fault cause, when the minimum emergency processes corresponding to different fault causes are consistent, the same emergency response model can be used.

[0038] For ease of understanding, the specific working process of the present invention is explained by taking a safety circuit failure as an example.

[0039] like Figure 2 The figure shows the principle diagram of the safety circuit and interlock release. The safety circuit is provided with detection points 1-4, and the interlock contact circuit is provided with monitoring points 5-8.

[0040] like Figure 3 As shown in the figure, in the emergency response process of the safety circuit based on the fault phenomenon model, after the on-site driver closes the car door and sliding door, he finds that the safety circuit of the on-site platform door system is blocked. The driver needs to open and close the sliding door again to try to restore the fault. If the fault is restored, the driver notifies the station and the train leaves the station normally. The station arranges personnel to rush to the platform and stand by at any time. If the fault is not restored, the station will notify the station to arrange personnel to rush to the platform to operate the interlock release. After the station personnel operate the interlock release, the driver confirms whether the train can leave the station normally. If it can leave the station normally, the train leaves the station normally. When the train enters the signal interlocking area, the station continues to operate the interlock release to ensure that the train enters and leaves the station normally. If the train cannot leave the station normally, the driver applies to the dispatcher for manual mode exit, and drives the train out of the station in manual mode after obtaining the dispatcher's authorization.

[0041] In the above process, emergency response personnel can only report and operate step by step according to the process corresponding to the fault phenomenon. In more serious cases, they may even remember the wrong process or make wrong operations due to nervousness, which often causes train delays.

[0042] To this end, this embodiment sets the interlock release independent part circuits to work normally. During actual operation, when prompting station personnel to release the interlock, they will be prompted: If the operation of interlock release is invalid, please apply to the dispatcher for manual mode exit in time; if the operation is valid, please remind the station personnel to maintain the interlock release mode in time; when the interlock release operation status is received, but it cannot be executed due to a fault in the interlock release circuit, the system will prompt the driver to apply to the dispatcher for manual mode exit on the driver display terminal, the dispatch terminal display terminal sound and light alarm alarm, the software interface reminds the dispatcher to issue manual driving mode authorization, click the authorization button or manually notify the driver, and the driver drives the train out of the station in manual mode; when the interlock release operation status is not received, the system will always maintain the prompt of "If the operation of interlock release is invalid, please apply to the dispatcher for manual mode exit in time".

[0043] like Figure 4As shown, voltage detection points 1-4 are set in the platform door system safety circuit, and voltage detection points 5-8 are set in the interlock contact circuit; according to the safety circuit and interlock release principle diagram, when the safety circuit fails, there are the following five states:

[0044] ① There is no voltage at detection point 1, detection point 2, and detection point 4, and the voltage at detection point 3 is normal

[0045] Since detection point 1 is the power supply end, the voltage of the platform door system needs to be maintained at 24V when it is working normally. Therefore, once the voltage at detection point 1 is abnormal, there will be no voltage at detection points 2 and 4. At this time, it is determined that the cause of the platform door safety circuit failure is the loss of source voltage. Reopening and closing the door will have no effect. At this time, emergency response model 1 is executed: the driver display terminal prompts the driver to notify the station personnel to release the operation interlock, the station display terminal sound and light alarm alarm, the software interface reminds the station to arrange personnel to rush to the platform to release the operation interlock, and the train leaves the station after the station personnel release the operation interlock.

[0046] ② There is no voltage at detection point 2 and detection point 4, and the voltage at detection point 1 and detection point 3 is normal

[0047] At this time, it is determined that the cause of the platform door safety circuit failure is a failure of a sliding door detection switch on that side. At this time, emergency response model 2 is executed: the driver display terminal prompts the driver to re-open and close the sliding door to try to restore the fault. The station display terminal sound and light alarm alarms, and the software interface reminds the station to arrange personnel to rush to the platform to prepare for the interlock release operation. After the driver reopens the door, if the fault is restored, the train leaves the station normally, and the station personnel continue to stand by on the platform; if the fault is not restored, the station personnel operate the interlock release and the train leaves the station.

[0048] ③ There is no voltage at detection point 4, and the voltages at detection points 1, 2, and 3 are normal.

[0049] At this time, it is determined that the cause of the platform door safety circuit failure is a safety circuit relay failure. Reopening the door will have no effect. At this time, emergency response model 1 is executed: the driver display terminal prompts the driver to notify the station personnel to release the operation interlock, the station display terminal sound and light alarm sounds, and the software interface reminds the station to arrange personnel to rush to the platform to release the operation interlock. The train leaves the station after the station personnel release the operation interlock.

[0050] ④ There is no voltage at detection point 3 and detection point 4, and the voltage at detection point 1 and detection point 2 is normal

[0051] Since the power supply of the platform door system's safety circuit relay and interlock release relay contacts is controlled by the same circuit breaker, the voltage needs to be maintained at 24V at all times. If only the safety circuit detection point is abnormal, it is determined that the cause of the platform door safety circuit failure is abnormal power supply to the safety circuit relay contacts. Reopening and closing the door will have no effect, and emergency response model 1 is executed: the driver display terminal prompts the driver to notify the station personnel to operate the interlock release, the station display terminal sound and light alarm sounds, the software interface reminds the station to arrange personnel to rush to the platform to operate the interlock release, and the train leaves the station after the station personnel operate the interlock release.

[0052] ⑤ There is no voltage at detection point 3 and detection point 4, no voltage at detection point 7, and the voltage at detection point 1 and detection point 2 is normal

[0053] At this time, it is determined that the cause of the platform door safety circuit failure is the abnormality of S2 circuit breaker. At this time, reopening the door and releasing the operation interlock will have no effect. Execute emergency response model 3: The driver display terminal prompts the driver to apply to the dispatcher for manual mode exit. The dispatch terminal displays the final sound and light alarm. The software interface reminds the dispatcher to issue manual driving mode authorization. After clicking the authorization button or manually notifying the driver, the driver drives the train out of the station in manual mode.

[0054] Further, such as Figure 4 As shown, taking the failure of a single sliding door on site as an example, the emergency response process under different priorities is explained.

[0055] When a single sliding door fails on site, it may cause the safety circuit on the entire side to be blocked, that is, there is no voltage at detection point 2 and detection point 4, and the voltage at detection point 1 and detection point 3 is normal. If a single sliding door alarm occurs on site and the safety circuit on the entire side is blocked, the system will prioritize the emergency response process for the single sliding door failure based on the logical relationship of the fault. First, the station staff will isolate the faulty sliding door.

[0056] If the safety circuit on the entire side returns to normal after isolation, it means that the fault is a single sliding door fault and the reason for the blockage of the safety circuit is the sliding door fault. After isolating the faulty sliding door, the emergency response is completed.

[0057] If the status of the safety circuit on the entire side is not restored after isolation, it means that there are two faults on site, and there is no connection between the safety circuit blockage and the single sliding door failure. After isolating the faulty sliding door, the system starts the safety circuit failure emergency response process. The response process is carried out according to the safety circuit failure in which there is no voltage at detection point 2 and detection point 4, and the voltage at detection point 1 and detection point 3 is normal.

[0058] It is understandable that before the fault is resolved, the display terminal will always display the platform door system PEDC fault. Please operate the PSL switch sliding door. After the fault is resolved, manually restore the system to the default working state.

[0059] It can be understood that in the specific implementation process, a fault repair standard is set for each emergency response model according to the cause of the fault, and the fault repair standard is analyzed based on the status monitoring data, fault status data and / or operation status data of the platform door system acquired again to see whether the fault repair standard is met. When the fault repair standard is met, the current emergency response model is exited and the default working state is automatically restored. For faults for which the recovery judgment standard cannot be set, the default working state is manually restored after the fault is repaired.

[0060] It can be understood that when a fault phenomenon occurs that cannot be identified and requires emergency handling, the emergency handling model is matched based on the fault phenomenon manually selected by the station personnel, and the relevant post personnel are notified to execute the matched emergency handling model.

[0061] The above method can ensure that when all fault phenomena occur, the emergency response model can be quickly found, thereby improving the efficiency of on-site emergency response.

[0062] Furthermore, taking the failure of the platform door system signal to open or close the door as an example, the emergency response process based on the abnormal operation records in the system is explained.

[0063] like Figure 5 As shown in the figure, when the platform door system works normally, the opening and closing of the sliding door is controlled by the opening and closing door command issued by the signal system. When the platform door system does not receive the control command of the signal system or the SIG control level fails, the driver needs to operate the PSL to control the opening and closing of the door. All the above controls belong to the trigger control mode. When no external trigger signal is received, the system will not generate any status data.

[0064] When the platform door system does not receive control instructions from the signal system, the system displays the relevant status of signal control and PSL operation through the driver and station service display terminals. When the system does not receive control instructions, the display terminal shows that the platform door system has not received any instructions, and prompts that if the train has opened the door, please operate the PSL to switch the sliding door.

[0065] If the system receives a signal door opening command, the display terminal displays the signal door opening command received by the platform door system, and prompts that if the train has closed its doors, please operate the PSL to close the sliding door.

[0066] If the SIG door opening command does not disappear after operating the PSL to close the door, the display terminal will display the signal door opening command received by the platform door system and prompt you to keep the PSL permission key switch in the permission position. This prevents the sliding door from automatically opening because the signal door opening command has not disappeared after the PSL permission key switch is turned back to the automatic position.

[0067] In case of a failure at the SIG control level and the system does not receive any signal control instructions, the system will display the relevant status of signal control and PSL operation through the driver and station service display terminals. When the system does not receive any control instructions, the display terminal will indicate that the platform door system has not received any instructions, and prompt that if the train has opened its doors, please operate the PSL to switch the sliding doors.

[0068] When the system receives the signal door opening command, the platform door system does not perform the door opening action and prompts a PEDC fault. After the system receives the PEDC fault command, the display terminal displays a platform door system PEDC fault. Please operate the PSL switch to slide the door.

[0069] If the SIG door opening command does not disappear after operating the PSL to close the door, the display terminal will display the signal door opening command received by the platform door system and prompt you to keep the PSL permission key switch in the permission position. This prevents the sliding door from automatically opening because the signal door opening command has not disappeared after the PSL permission key switch is turned back to the automatic position.

[0070] Example 2

[0071] This embodiment provides a platform door failure emergency handling analysis system, such as Figure 6 As shown, it includes a server, a platform door system, a status monitoring module and display terminals corresponding to different positions;

[0072] The platform door system is used to complete corresponding actions according to the control commands of the server and on-site emergency response personnel, upload fault status data to the server when a fault occurs, and periodically monitor

[0073] The status monitoring module is connected to the platform door system, and is used to periodically read the operation record data and status monitoring data in the platform door system and upload them to the server, and periodically upload its own status monitoring data to the server, wherein the key nodes of the process are found by analyzing the existing platform door fault emergency handling process corresponding to the fault phenomenon that can be identified and needs emergency handling, and corresponding status measurement points are added to the key nodes of the process to form key measurement points, and it is judged one by one whether the status of each key node of the process can be monitored by the platform door system. If it cannot be monitored by the platform door system, a status measurement point is set at the current key node of the process, and the current status measurement point is monitored by the status monitoring module to obtain the status monitoring data of the status measurement point;

[0074] The server has built-in multiple emergency response models for fault phenomena that can be identified and require emergency response, each emergency response model corresponds to at least one fault cause, including a minimum emergency processing flow executed when solving the fault cause, and each emergency response model is assigned a corresponding trigger mode according to the trigger source type of the fault cause, the trigger mode includes an abnormal state monitoring data trigger mode, an abnormal operation state data trigger mode and an abnormal fault state data trigger mode, wherein different trigger modes are assigned different priorities according to the logical relationship between the fault causes;

[0075] The server obtains the status monitoring data of the status monitoring module and the status monitoring data, operation status data and fault status data of the platform door system, and performs analysis to determine the matching trigger mode and fault cause; determines the emergency response model according to the matching trigger mode and fault cause, and when there is only one emergency response model, notifies the relevant post personnel to execute the emergency response model through the display terminal; when there are multiple emergency response models, sorts the multiple emergency response models in order of trigger mode priority from high to low, and notifies the relevant post personnel to execute the emergency response model corresponding to the high-priority trigger mode through the display terminal, and analyzes whether the currently executed emergency response model is valid based on the status monitoring data, fault status data and operation status data of the platform door system acquired again. If it is valid, notify the relevant post personnel through the display terminal to keep executing the current emergency response model; if it is invalid, notify the relevant post personnel through the display terminal to execute the emergency response model corresponding to the low-priority trigger mode.

[0076] In a specific implementation, the status monitoring module includes a communication unit, a remote communication unit, a mode switch and a voltage detection unit. The voltage detection unit is used to perform voltage detection on key measurement points to obtain status monitoring data; the communication unit is connected to the platform door system to receive the status monitoring data, operating status data and fault status data uploaded by the platform door system; the remote communication unit is connected to the server to upload the status monitoring data, operating status data and fault status data uploaded by the platform door system and the status monitoring data obtained by the voltage detection unit to the server; the mode switch is used to switch the working mode of the status monitoring module.

[0077] Preferably, the status monitoring module also includes a master-slave switching detection unit and at least one backup voltage detection unit. The master-slave switching detection unit is used to compare the status monitoring data with the status monitoring data of other status measurement points that have a logical relationship with the status measurement point after acquiring the status monitoring data. If the logical states are consistent, the status monitoring data is determined to be valid; otherwise, the status monitoring data is determined to be invalid, the current voltage detection unit is abnormal, and the switch is made to the backup voltage detection unit.

[0078] The above arrangement can timely switch to the backup voltage detection unit when the voltage detection unit is abnormal, so that the system can obtain normal and effective key measurement point status monitoring data when performing fault analysis.

[0079] It can be understood that, preferably, the relevant positions include drivers, station staff and dispatchers. The display terminal set up for each position only displays the emergency response model related to this profession. After the personnel perform the operation, the system determines whether the operation is valid and automatically updates the next emergency operation step according to the operation result.

[0080] Furthermore, the server can perform line network-level data analysis, and the platform door system industrial computer, driver, and station service display terminals can also perform station-level data analysis.

[0081] Furthermore, the emergency response analysis system is also provided with a fault diagnosis function, and when a fault occurs, the fault cause and the fault troubleshooting process are sent to the maintenance personnel's handheld terminal. After receiving the information, the maintenance personnel rush to the scene in time to handle the fault.

[0082] Furthermore, when an abnormality occurs in the system status monitoring data, if it does not involve relevant operations and does not affect the normal operation of the platform door system, the system will send relevant information to the maintenance personnel and notify them to perform repairs.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
