Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and particularly to a platform gap detection and control method and device. Background Art

[0002] In recent years, with the development of the rail transit industry, subway lines with fully automatic operation systems have been built and operated in various cities. With the diversification of construction methods in each city, each system manufacturer is making efforts to further improve the automation level and the comprehensive competitiveness of products. Currently, considering the large difference in passenger flow between off-peak and peak hours on each rail transit line, various trains such as 8-car trains, 6-car trains, or 4-car trains have been tried to be configured on the line. 8-car trains are put into operation more during peak hours, and other car trains are put into operation more during off-peak hours. Combining them with each other improves the operation efficiency, reduces the operation cost, and avoids the situation of long waiting for trains during peak hours or excessive waste of resources during off-peak hours. For example, considering the unstable passenger flow from the airport to the urban area, in order to ensure the operation efficiency, a plan of mixed running of multiple formations such as 4 / 8 or 6 / 8 on the same line during the operation period has been proposed.

[0003] Currently, in order to ensure the safety of the gap between the train and the platform after passengers get on and off, each rail transit line is gradually popularizing the configuration of a platform gap detection system, and at the same time realizing linkage protection with the line signal system to improve the safety of train departure on the line. Currently, for the mixed operation of multiple formations of trains on the line, the processing logic of starting and stopping the gap detection device during the boarding and alighting operations of 8-car trains entering the station is the same as that of other car trains entering the station for boarding and alighting. Other car trains are shorter than 8-car trains, and the corresponding overlapping space between the train and the platform is different. For example, compared with an 8-car train, a 4-car train has a difference of 4 train lengths, and correspondingly, the overlapping space with the platform is also 4 train lengths less. However, because the signal system processes the platform gap detection of multiple formations of trains in the same way, when multiple formations of trains run mixed, false alarms will occur (for other formations of trains corresponding to the platform, no obstacle is detected by the train position detection, but no obstacle is found on the site), which affects the departure of the train at the platform. It is also necessary for the platform staff to conduct on-site inspections and confirmations and operations to ensure the departure of the train at the platform. Therefore, once a false alarm occurs, it will cause trouble to both passengers and staff.

[0004] With the rapid development of urban rail transit, on the same line, there are more and more trains with different formations, in order to achieve flexible adaptation of the line and transport capacity. However, the platform gap detection system on the line cannot flexibly identify multiple formation trains. No matter what formation train stops at the station, the gap detection system will detect according to the train with the most formations, which is likely to cause false alarms in the detection results, increase the detection and identification feedback time, affect the departure efficiency, and not only increase the maintenance workload for the operation unit but also may cause delays to the operating trains.

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0031] The following combines Figures 1-11 to describe the platform gap detection control method and device of the present invention. Figure 1 is a schematic flowchart of the platform gap detection control method provided by the present invention. As Figure 1 shown, the present invention provides a platform gap detection control method, including:

[0032] 101. Receive a start detection command sent by the on-vehicle signal system. Among them, the train formation types to which the on-vehicle signal system belongs include a first formation type and a second formation type, and the on-vehicle signal system sends a start detection command corresponding one-to-one to the formation type of the train to which it belongs.

[0033] With the rapid development of urban rail transit, on the same line, there are more and more trains with different formations to achieve flexible adaptation of the line and transport capacity. However, the platform gap detection system on the line cannot flexibly identify multiple formation trains. No matter what formation train stops at the station, the gap detection system will detect according to the maximum formation train stop, which is likely to cause false detection results, increase the detection and identification feedback time, affect the departure efficiency, and not only increase the maintenance workload for the operation unit but also may cause the phenomenon of operation train delays.

[0034] The method of the embodiment of the present invention is applied to the interlocking system. When the door-platform door linkage function is normal, after the boarding and alighting operation is completed, according to the requirements of the gap detection start timing of each line, the on-vehicle signal system sends a start gap detection command to the interlocking (including scenarios of driver manual door closing, signal system automatic door closing, platform door closing, and central remote door closing).

[0035] Among them, the train formation types to which the on-vehicle signal system belongs include more than two types, that is, the first formation type and the second formation type mentioned in the above 101 (for example, including 8-formation trains and 6-formation trains). For simplicity of description, the first formation is hereinafter referred to as the X formation, and the second formation is referred to as the Y formation. The on-vehicle signal system sends different start detection commands according to the formation type of the train to which it belongs. For example, after the train parking operation is completed, the on-vehicle signal system of the X formation sends a start X formation detection command, and the on-vehicle signal system of the Y formation sends a start Y formation detection command.

[0036] 102. In the case where the start detection command is a start first formation type detection command, send an instruction to start the first formation type detection to the gap detection system. In the case where the start detection command is a start second formation type detection command, send an instruction to start the second formation type detection to the gap detection system.

[0037] As Figure 2 and Figure 3As shown, when opening or closing the platform screen door, when the interlocking system determines that the start conditions for detecting the gaps of each line are met (boarding and alighting operations are completed), according to the type of the start gap detection X or Y formation command of the on-vehicle signal system, it sends the corresponding start detection X formation instruction or the start detection Y formation instruction to the gap detection system respectively.

[0038] 103. Start timing the detection result, and in the case that the information of detecting an obstacle sent by the gap detection system is not received after a preset duration, send the no-obstacle information to the on-vehicle signal system.

[0039] After the interlocking system sends the instruction to start detecting the X or Y formation to the gap detection system, it starts supervising and timing the detection result. Before receiving the instruction to stop detecting the X formation or Y formation, it continuously conducts the detection corresponding to the X formation or the detection corresponding to the Y formation, and feeds back the gap detection result to the ground interlocking system in real time.

[0040] After a preset duration, if the interlocking system does not receive the information of detecting an obstacle sent by the gap detection system until 2.4 s (configurable) continuously, it is considered that there is no obstacle, and it sends the no-obstacle information to the on-vehicle signal system, and the train starts the automatic driving of the signal system.

[0041] Specifically, after receiving the instruction to start detecting the X or Y formation, the gap detection system starts detecting. The gap detection system aggregates the detection signals of the platforms of the X or Y formation on one side of the platform into a detection signal and sends it to the interlocking system, and finally feeds it back to the signal system. When the gap detection system detects that there are no passengers or large items in the gap between the platform screen door and the train, it feeds back the "no-obstacle information" to the signal system; when any one of the detection beams of the gap detection system detects a passenger or a large item, it feeds back the "obstacle information" to the signal system.

[0042] Optionally, the obstacle information received by the signal system is alarmed and displayed at the local workstation, and at the same time, the gap detection system gives a prompt at the platform controller; when the gap detection system has not completed the detection, it reports to the signal system that there is an obstacle.

[0043] Optionally, to reduce the impact of the failure of the gap detection system on train operation, the gap detection system is provided with an "interlock release" switch. When the gap detection system reports an obstacle all the time due to a failure, the gap detection system can be manually interlock-released by special means. After the signal system receives this interlock release signal, it no longer supervises the gap detection result.

[0044] Optionally, the transmission channels for sending the instruction to start detecting the first formation type and the instruction to start detecting the second formation type, and for receiving the obstacle detection feedback information sent by the gap detection system all adopt secure channels.

[0045] Optionally, the gap detection system and the on-vehicle signal system are provided with a recording function for transmitting and receiving interface information.

[0046] Optionally, the gap detection system sends the operating status of all gap detection devices at the station and the detected fault information to the on-vehicle signal system, and the on-vehicle signal system uploads it to the station control room for display.

[0047] In the platform gap detection control method of the present invention, the interlocking system issues different detection instructions according to the detection commands of different formation types sent by the on-vehicle signal system respectively, which is consistent with the train processing logic of the rail transit line. When the first formation train enters the station, a start detection command for the first formation is sent. By adding a set of start gap detection instructions to the original rail transit line gap detection control method, gap detection can be carried out separately according to the different situations of the first formation and the second formation, thereby reducing the system false alarm rate and improving the operation efficiency of the train system. In addition, when the number of the first formation < the number of the second formation, if a fault occurs in the second formation gap detection device, it does not affect the start and stop gap detection of the first formation train, further ensuring the false alarm rate and improving the operation efficiency of the train system.

[0048] In one embodiment, receiving the start detection command sent by the on-vehicle signal system includes: receiving the pulse signal sent by the on-vehicle signal system after the train stops; judging whether the start detection command sent by the on-vehicle signal system is a start detection command for the first formation type or a start detection command for the second formation type according to the parsing result of the pulse signal.

[0049] In the present invention, the on-vehicle signal system provides the "start detection command for formation X" and the "start detection command for formation Y" to the gap detection system, and may also include the "stop detection command for formation X" and the "stop detection command for formation Y". Among them, the above start and stop commands are pulse signals (such as a pulse width not less than 1.5 s). Correspondingly, the interlocking system judges which formation's start detection or stop detection command it is specifically according to the parsing result of the pulse signal.

[0050] The platform gap detection control method of the present invention sends a start detection command through a pulse signal, is not easily affected by the environment, and can improve the reliability of detection start.

[0051] In one embodiment, sending the instruction to start the first formation type detection to the gap detection system includes: sending the instruction to start the first formation type detection to the gap detection system by controlling the closing of the first start detection relay; correspondingly, sending the instruction to start the second formation type detection to the gap detection system includes: sending the instruction to start the second formation type detection to the gap detection system by controlling the closing of the second start detection relay.

[0052] At present, the interfaces for mainstream gap detection and signals are all relay interfaces. The circuit design complies with the principle of fail-safe. The interface circuit uses a relay, and a safety-type relay is adopted. The start or stop of gap detection is achieved through the interaction information between the signal system and gap detection, and the signal system is informed whether there is a foreign object.

[0053] This set of solutions cannot meet the requirement of starting the corresponding gap detection device for different formations after the train formation of multiple formations enters the station for boarding and alighting operations. It can only start and stop gap detection within the maximum range of platform gap detection to ensure safety.

[0054] Such as Figures 4-7 As shown, in view of the above disadvantages, the present invention analyzes and sorts out the existing line interfaces of the interlocking-platform gap detection system, and realizes each instruction by adding a relay for starting or stopping gap detection. The instructions include an instruction for starting the detection of X-type formation trains and an instruction for starting the detection of Y-type formation trains. In addition, it may also include an instruction for stopping the detection of X-type formation trains and an instruction for stopping the detection of Y-type formation trains. Correspondingly, it includes an X start detection relay and a Y start detection relay, as well as an X stop detection relay and a Y stop detection relay. Among them, different start detection relays or stop detection relays are respectively set for the up line and the down line in the figure.

[0055] The present invention starts and stops the gap detection device in one-to-one correspondence with the number of train formations after the boarding and alighting operations of multiple formations entering and docking at the station. For example, when the X formation docks, the corresponding gap detection relay for the X formation is started or stopped, and when the Y formation docks, the corresponding gap detection relay for the Y formation is started or stopped. When an instruction for starting the detection of the X formation type needs to be sent, it can be achieved by closing the X start detection relay.

[0056] The platform gap detection control method of the embodiment of the present invention sends an instruction for starting the detection of the first formation type to the gap detection system by controlling the closing of the first start detection relay; and sends an instruction for starting the detection of the second formation type to the gap detection system by controlling the closing of the second start detection relay, which is beneficial to ensuring the safety and reliability of gap detection.

[0057] In one embodiment, after sending the obstacle-free information to the on-vehicle signal system, it further includes: receiving a stop detection command sent by the on-vehicle signal system after the train departs; when the stop detection command is a command for stopping the detection of the first formation type, sending an instruction for stopping the detection of the first formation type to the gap detection system by controlling the closing of the first stop detection relay; when the stop detection command is a command for stopping the detection of the second formation type, sending an instruction for stopping the detection of the second formation type to the gap detection system by controlling the closing of the second stop detection relay.

[0058] Combined with the aboveFigures 4-7 In the embodiment of the present invention, according to the requirements of the detection opportunity of the stop gap of each line, the on-vehicle signal system of the signal system sends the "Stop Detection X / Y" command to the interlocking, and the interlocking forwards it to the gap detection system, and the gap detection system enters the standby state.

[0059] Among them, the termination of the corresponding gap detection is realized through the X stop detection relay and the Y stop detection relay.

[0060] The platform gap detection control method of the embodiment of the present invention, when the detection opportunity of the stop gap is required, by controlling the closing of the first or second stop detection relay, sends an instruction to the gap detection system to stop detecting the first or second formation type detection, avoiding the situation that the gap detection system always reports obstacles, and improving the reliability of obstacle detection.

[0061] In one embodiment, the sending an instruction to the gap detection system to start the first formation type detection by controlling the closing of the first start detection relay includes: by controlling the closing of the first start detection relay, connecting the relay circuit for detecting obstacles in the first formation, so that the gap detection system performs gap detection on the arriving train through the gap detection device corresponding to the vehicles of the first formation type; correspondingly, the sending an instruction to the gap detection system to start the second formation type detection by controlling the closing of the second start detection relay includes: by controlling the closing of the second start detection relay, connecting the relay circuit for detecting obstacles in the second formation, so that the gap detection system performs gap detection on the arriving train through the gap detection device corresponding to the vehicles of the second formation type.

[0062] The platform gap detection device is mainly a protection device to prevent harm to personnel when the train departs when there are foreign objects or personnel between the train and the platform door. After the train arrives at the station and completes the boarding and alighting operations and closes the doors and platform doors, at this time the signal system will inform the gap detection system that it can start detection. The continuous detection time can be configured by the system for a certain time according to different lines. During this certain time, if no foreign objects are detected by the gap detection, it will inform the signal system. At this time, the signal system controls the train to depart normally and run to the next station. If foreign objects are detected by the gap detection, the gap detection informs the signal system, and the signal system controls the train not to be allowed to depart. The gap detection device greatly protects the safety of passengers.

[0063] In the present invention, the gap detection device can synchronously implement the detection functions corresponding to multiple formation trains. Specifically, the gap detection devices can be set respectively according to different formation types, or some gap detection devices at the same positions can be reused to realize the gap detection of the corresponding formation trains for multiple formation trains when starting at the platform.

[0064] Whether the gap detection device is set separately for different groups or the gap detection device at the same position is reused, when the number of groups X < Y, the normal use of the gap detection X state is not affected when the remaining detector state of the Y part of the gap detection fails.

[0065] Optionally, after the gap detection system enters the standby mode (i.e., the normal state where the interlocking does not require startup), the relay that feeds back the obstacle detection information from the gap detection system to the signal system remains in the dropped state, indicating that there is an obstacle.

[0066] Such as Figure 8 and Figure 9 As shown in the figure, where RD is the resistor, LZ is the positive pole, LF is the negative pole, SJXZ and SJXF are the positive and negative poles of the up-gap detection respectively; XJXZ and XJXF are the positive and negative poles of the down-gap detection respectively, F indicates that the resistor needs to be installed on the lightning protection distribution cabinet, and 1, 2, 3, and 4 are the terminal numbers. In the embodiment of the present invention, the detection is set separately according to the up-train and down-train conditions. The up-train start detection relay for X is the first start detection relay, and the up-train start detection relay for Y is the second start detection relay. The loop corresponding to the up-train obstacle detection relay for X is the relay loop for the first group obstacle detection, and the loop corresponding to the up-train obstacle detection relay for Y is the relay loop for the second group obstacle detection. Among them, the embodiment in the figure also detects the bypass.

[0067] In the platform gap detection control method of the embodiment of the present invention, when sending an instruction to start the detection of the first or second group type to the gap detection system by controlling the closing of the first or second start detection relay, the relay loop for the first or second group obstacle detection is connected, so that the gap detection system can detect the gap of the arriving train through the gap detection device corresponding to the first group or the second type of vehicle. The gap detection is realized by controlling the relay loop through the relay, which improves the reliability of the gap detection and is not easily interfered by external signals.

[0068] In one embodiment, after receiving the start detection command sent by the on-vehicle signal system, it further includes: when the information of detecting an obstacle sent by the gap detection system is received within a preset time period, reset the detection result timing, and until the information of detecting an obstacle sent by the gap detection system is not received after the preset time period, send the information of no obstacle to the on-vehicle signal system.

[0069] During the timing process, once an obstacle is detected, the timing is restarted until no fault is detected within the preset time period. Among them, when the gap detection system reports an obstacle again, if the train has started, emergency braking is performed for manual handling. By resetting the detection result timing when the information of detecting an obstacle sent by the gap detection system is received within the preset time period, false alarms caused by interference can be avoided. Only when no obstacle is detected within the preset time period can it be reliably concluded that there is no obstacle information, and a detection result that meets the departure condition and has high reliability is obtained.
