Description

Technical Field

[0001] The present invention relates to the technical field of rail transit safety protection, and particularly to a safety protection method for the reverse operation of a communication train. Background Art

[0002] In the urban rail transit signal system, under the control level of the CBTC system, trains cannot run in the reverse direction. However, in the face of a fault scenario, if a communication train continues to run after the fault is handled, it may stay for too long, affecting passengers' travel and causing panic among passengers. At this time, it is often necessary to cut off the signal system or use the interlocking system in combination with the reverse signal to achieve the reverse operation of the communication train.

[0003] When the line signal equipment does not have a reverse signal for supporting the arrangement of reverse routes, it is necessary to cut off the signal system to achieve reverse operation control. The train operation safety after cutting off the signal system is completely ensured by manual operation. For driverless trains, the central dispatcher needs to send a driver to board the train to take over the driving. This manual train operation safety control method has high requirements for drivers and is prone to errors. When the line signal equipment is equipped with a reverse signal for supporting the arrangement of reverse routes, its dispatching is affected by the fault location and the signal location. When the signal is arranged far away, if it is necessary to arrange the route from this signal to another signal, the central dispatcher needs to check that there is no conflicting forward route lock in all possible reverse operation areas before arranging the reverse route. There are many dispatching operations that need to be performed manually, such as area fault resolution or canceling the original forward locked route, etc. The dispatching workload is large and it is easy to make mistakes.

[0004] It can be seen that for the existing reverse operation control of communication trains, in order to ensure the safety during the reverse operation, manual intervention of the dispatching center is required. Affected by the fault location, the dispatching content is relatively complex and changeable, easy to make mistakes, and unable to ensure the safety of communication trains during the reverse operation. Summary of the Invention

[0005] The object of the present invention is to overcome the disadvantages in the prior art that in a fault scenario, the reverse operation control of a communication train requires manual intervention of the dispatching center, the dispatching workload is large and easy to make mistakes, and the safety during the reverse operation is relatively low. A safety protection method for the reverse operation of a communication train is provided. When the train runs in the reverse direction, based on the electronic map, the basic information in the reverse operation area of the train is analyzed, and then corresponding route state settings, movement authorizations and other dispatching operations are automatically performed according to the corresponding reverse operation area information. The reverse operation control of the communication train can be achieved without cutting off the signal system, reducing the participation of manual operation in the reverse operation control, reducing the probability of dispatching errors, and ensuring the safety of the communication train during the reverse operation.

[0006] The object of the present invention is achieved by the following technical solutions:

[0007] A safety protection method for a communication train running in the reverse direction, comprising:

[0008] Issuing a reverse running command and a reverse running destination code to the target train. Based on the electronic map, the target train obtains reverse running area information according to the parking position and activates the reverse running area;

[0009] Based on the reverse running area information, controlling the turnout in the reverse running area to rotate to the desired position and setting the route status of the corresponding section in the reverse running area;

[0010] Based on the reverse running area activation information and the train position, switching the locking direction of the section where the train body is located, detecting and judging the reverse movement authorization calculation conditions corresponding to the target train, and calculating the movement authorization;

[0011] Based on the reverse running destination code and the movement authorization, controlling the target train to run to the corresponding target platform and stop.

[0012] By analyzing the basic information in the reverse running area of the train based on the electronic map, corresponding route status settings, movement authorizations and other dispatching operations can be automatically performed according to the corresponding reverse running area information. The reverse running control of the communication train can be realized without cutting off the signal system, reducing the workload of organizing personnel and manual operations during reverse running. The signal system ensures the safety of the train running in the reverse direction, reduces the participation of manual operation in reverse running control, reduces the probability of dispatching errors, and guarantees the safety of the communication train during reverse running. And it no longer depends on the fixed route mode of the reverse signal machine. The parking position of the communication train is not restricted, and the reverse running control of the communication train starting from any point can be applied, and the existing station yard equipment layout can be applied more flexibly.

[0013] Further, the reverse running area information includes the starting platform, the target platform, reverse running direction information, section list, turnout information, turnout desired position and reverse running stop point information.

[0014] Further, the controlling the turnout in the reverse running area to rotate to the desired position and setting the route status of the corresponding section in the reverse running area based on the reverse running area information includes:

[0015] Determining the target platform for reverse running according to the reverse running stop point information, canceling all forward routes to the target platform, and prohibiting arranging forward routes to the target platform;

[0016] Sending a stop command to the target train to control the target train running in the reverse direction to brake and stop;

[0017] According to the parking section where the target train brakes to a stop, unlock the route between the target platform and the parking section, and keep the route between the starting platform of the target train and the corresponding parking position locked.

[0018] Further, it also includes:

[0019] The target train automatically changes ends according to the reverse operation command and sends a reverse operation area activation application based on the train position after changing ends;

[0020] Identify and adjust the switch position according to the train position, reverse operation destination code, switch information, and expected switch position;

[0021] Restrict the entry of trains into the corresponding area, and activate the reverse operation area when there are no other vehicles between the train position and the target platform.

[0022] Further, the identifying and adjusting the switch position according to the train position, reverse operation destination code, switch information, and expected switch position includes:

[0023] Determine the reverse operation path of the target train according to the train position and the reverse destination code;

[0024] Screen the corresponding switches on the reverse operation path of the target train according to the switch information, and determine whether the screened switches are in the corresponding expected switch positions;

[0025] When the screened switches are not in the expected switch positions, issue corresponding switch operation commands to operate the switches to the corresponding expected switch positions.

[0026] Further, after activating the reverse operation area, it also executes:

[0027] Determine the reverse operation path of the target train according to the train position and the reverse destination code;

[0028] Initiate a reverse locking application for the corresponding section according to the reverse operation path;

[0029] Based on the reverse locking application, prohibit the establishment of a forward route including the corresponding section, close the signal of the forward route that has been opened in the corresponding section, and lock each reverse sub-route in units of sections one by one;

[0030] When all reverse sub-routes are locked, switch the locking direction of the section where the target train is located;

[0031] When the locking direction of the section where the target train is located after switching is consistent with the reverse operation direction, calculate the movement authorization.

[0032] Further, before issuing the reverse operation command and the reverse operation destination code to the target train, it also executes:

[0033] Determine the reverse operation path of the target train according to the train position and the reverse destination code;

[0034] Pre-check whether there is a forward route conflicting with the reverse operation path;

[0035] When there is a forward route conflicting with the reverse operation path, issue an alarm and reject the issuance of the reverse operation command and the reverse operation destination code.

[0036] Furthermore, it also includes:

[0037] After the target train arrives at the target platform, cancel the corresponding reverse operation area activation application;

[0038] When the reverse operation area activation applications of all trains performing reverse operation in the reverse operation area are cancelled, or when it is recognized that there are no trains that need to perform reverse operation in the reverse operation area, cancel all reverse locking applications for the sections in the reverse operation area, and unlock the sub-routes after meeting the sub-route unlocking conditions.

[0039] Furthermore, it also includes:

[0040] When the number of trains performing reverse operation in the reverse operation area is greater than one, take the train closest to the target platform as the target train, and control the target train to run to the corresponding target platform and stop;

[0041] After the train closest to the target platform leaves the reverse operation area, re-select the next train performing reverse operation as the target train until all trains performing reverse operation in the reverse operation area are controlled to run to the corresponding target platforms.

[0042] Furthermore, the controlling the target train to run to the corresponding target platform and stop based on the reverse operation destination code and the movement authorization also includes:

[0043] After the target train arrives at the target platform, conduct passenger clearance for the target train, and judge the forward operation conditions of the target platform;

[0044] When the target platform has the forward operation conditions, adjust the switch positions of the corresponding sections and control the target train to perform forward operation;

[0045] When the target platform does not have the forward operation conditions, re-set the reverse operation area information, control the target train to run to the next target platform until the platform where the target train is located meets the forward operation conditions.

[0046] The beneficial effects of the present invention are:

[0047] (1) Analyze the basic information within the reverse running area of the train based on the electronic map, and thus automatically perform corresponding route status settings, movement authorizations and other dispatching operations according to the reverse running area information. Without cutting off the signal system, the reverse running control of the communication train can be achieved, reducing the workload of organizing personnel and manual operations during reverse running. The signal system ensures the safety of the train during reverse running, reduces the participation of manual operations in reverse running control, reduces the probability of dispatching errors, and guarantees the safety of the communication train during reverse running. Moreover, it no longer depends on the fixed route mode of the reverse signal machine. The parking position of the communication train is not restricted, and the reverse running control of the communication train starting from any point can be applied more flexibly, and the existing station yard equipment layout can be applied more flexibly.

[0048] (2) The reverse running control is only carried out for a certain train within the reverse running area and will not control the overall reverse running area, effectively avoiding the impact on the normal operation of the communication trains that do not need to run in reverse within the reverse running area, and can be applied more flexibly to different operation scenarios. Description of the Drawings

[0049] Figure 1 is a schematic diagram of a train operation line according to an embodiment of the present invention;

[0050] Figure 2 is a schematic flow chart of the present invention;

[0051] Figure 3 is a data flow diagram during the reverse running of a train according to an embodiment of the present invention. Detailed Embodiment

[0052] The present invention will be further described below with reference to the drawings and embodiments.

[0053] Embodiment:

[0054] Refer to Figure 1 the shown train operation line. In this operation line, there are train A and train B in operation, the platforms in section G1604 and the platforms in section G1612, signal machine S01, signal machine S02, signal machine S03, and reverse signal machine S05.

[0055] During the forward operation of Train A, if a fault occurs ahead and it cannot continue to run forward, Train A stops on section G1608. At this time, if Train A wants to run backward to the platform in section G1604, the central dispatcher needs to notify the driver to cut off the ATP (Automatic Train Protection) system before running backward. The driving safety after cutting off the ATP system is completely guaranteed by manual operation. For driverless trains, the central dispatcher also needs to dispatch a driver to board the train to take over the driving. During the forward operation of Train B, if a fault occurs ahead and it cannot continue to run forward, Train B stops on section G1610. At this time, if Train B wants to run backward to the platform in section G1604, without cutting off the ATP system, the central dispatcher needs to arrange an approach with signal S03 and reverse signal S05 as the start and end points on the premise of checking that there is no conflicting forward route lock in all possible backward running areas. If there is no reverse signal S05 in the actual line layout, it will involve a longer and farther approach, and there will be more operations for the dispatcher, such as zone fault resolution or cancellation of the original forward locked route.

[0056] It can be seen that the existing reverse operation control for communication trains is overly intervened by humans, prone to errors, and the safety cannot be guaranteed. Therefore, in view of the above problems, this embodiment proposes a safety protection method for the reverse operation of communication trains, as Figure 2 shown, including:

[0057] Send a reverse operation command and a reverse operation destination code to the target train. Based on the electronic map, the target train obtains reverse operation area information according to the parking position and activates the reverse operation area;

[0058] Based on the reverse operation area information, control the turnout in the reverse operation area to rotate to the desired position and set the approach status of the corresponding section in the reverse operation area;

[0059] Based on the reverse operation area activation information and the train position, switch the locking direction of the section where the train body is located, detect and judge the reverse movement authorization calculation conditions corresponding to the target train, and calculate the movement authorization;

[0060] Based on the reverse operation destination code and the movement authorization, control the target train to run to the corresponding target platform and stop.

[0061] When a fault occurs in the train operation path, control the train to stop, send a reverse operation command and a reverse operation destination code to the target train. Based on the electronic map, the target train obtains reverse operation area information according to the parking position. The reverse operation area information includes the starting platform, the target platform, the reverse operation direction information, the section list, the turnout information, the desired turnout position, and the reverse operation stop point information.

[0062] Among them, the starting platform is the next platform in the forward direction after the train stops, the target platform is the next platform in the reverse direction after the train stops, the reverse running direction information includes the running direction of the train in reverse, the section list includes all sections that the train will pass through in reverse, the turnout information includes all relevant turnouts and their states, the expected turnout position is the position to which the turnout needs to be adjusted for reverse running, and the reverse running stop point information includes the points where the train may need to stop during reverse running.

[0063] Based on Figure 1 the shown train operation line, taking train A running forward from left to right as an example, where a fault occurs in the forward section G1612 and the train cannot enter, and it is necessary to organize train A in the section to run in reverse. The specific reverse running area information is as follows:

[0064] Starting platform: Section G1612;

[0065] Target platform: Section G1604;

[0066] Reverse running direction: from right to left;

[0067] Included section list (including the next section of the reverse running destination): Section G1602, Section G1604, Section G1606, Section G1608, Section G1610, Section G1612;

[0068] Turnouts: P1602, P1606;

[0069] Expected turnout positions: P1602 in normal position, P1606 in normal position;

[0070] Reverse running stop point: SP01.

[0071] Once the reverse running area information is determined, the central dispatcher immediately sends a stop command to the target train to ensure the safe stop of the train. At the same time, according to the reverse running area information, the route status of relevant sections is adjusted to ensure that the reverse running path is safe and unobstructed.

[0072] Specifically, send a stop command to the target train to control the braking and stopping of the target train running in reverse. Based on the reverse running area information, operate and control the turnouts in the reverse running area to rotate to the expected positions, and set the route status of the corresponding sections in the reverse running area, including:

[0073] Determine the target platform for reverse running according to the reverse running stop point information, cancel all forward routes to the target platform, and prohibit arranging forward routes to the target platform;

[0074] According to the parking section where the target train brakes to a stop, unlock the route between the target platform and the parking section, and keep the route between the starting platform of the target train and the corresponding parking position locked.

[0075] Taking the above reverse operation area information as an example, after determining the reverse operation area information, it is necessary to cancel all the forward routes to the section G1604 where the target platform is located, and prohibit arranging forward routes to the section G1604 where the target platform is located, and then send a stop command to train A to control its braking to a stop.

[0076] After train A completes parking and stops in section G1608, accordingly, further control the normal route unlocking of section G1602, section G1604, and section G1606, and keep the routes of section G1608, section G1610, and section G1612 locked.

[0077] After completing the above route status setting, the corresponding reverse operation command and reverse destination code can be sent.

[0078] To ensure the safe operation of the train, before sending the reverse operation command and reverse operation destination code to the target train, the following is also executed:

[0079] Determine the reverse operation path of the target train according to the train position and the reverse destination code;

[0080] Pre-check whether there is a forward route conflicting with the reverse operation path;

[0081] When there is a forward route conflicting with the reverse operation path, issue an alarm and reject sending the reverse operation command and reverse operation destination code.

[0082] If there is no forward route conflicting with the reverse operation path, the reverse operation command and reverse operation destination code can be normally sent.

[0083] After obtaining the train position and the reverse destination code, the reverse operation path that the target train needs to take can be determined by combining factors such as the track layout and signal equipment along the way.

[0084] After determining the reverse operation path, it can be analyzed according to the corresponding train operation diagram to judge whether the target train will conflict with the trains running or about to run in the forward direction. The conflict may occur in key areas such as the same track, the same platform, or the switch. When detecting a forward route conflicting with the reverse operation path, an alarm message should be immediately issued to notify relevant personnel of the potential conflict risk. At the same time, reject sending the reverse operation command and reverse operation destination code to prevent the target train from straying into the conflict area and ensure the safe operation of the target train.

[0085] Before the target train determines to execute reverse operation, it is also necessary to detect relevant reverse execution conditions, such as train status, signal status, turnout position, etc., to ensure the safety and feasibility of reverse operation. When all execution conditions are met, the reverse operation area is activated, which means that the relevant signals and turnouts have been adjusted in place, and the target train can start reverse operation. At the same time, the movement authority is calculated. The movement authority is the maximum distance that the target train can travel safely during reverse operation.

[0086] Specifically, after issuing the reverse operation command and the reverse operation destination code, the following operations are also performed:

[0087] The target train automatically changes ends according to the reverse operation command and sends an application to activate the reverse operation area based on the train position after changing ends;

[0088] Identify and adjust the turnout position according to the train position, reverse operation destination code, turnout information and expected turnout position;

[0089] Restrict the entry of trains into the corresponding area, and activate the reverse operation area when there are no other vehicles between the train position and the target platform.

[0090] After receiving the reverse operation command, the target train will automatically change ends of the on-vehicle controller when stopped, and then send an application to activate the reverse operation area to the Zone Controller (ZC) and the Automatic Train Supervision (ATS) system based on the train position.

[0091] Among them, when the ATS system receives the application to activate the reverse operation area, it will identify and adjust the turnout position to ensure the smooth progress of the subsequent reverse operation of the target train.

[0092] Specifically, the identifying and adjusting the turnout position according to the train position, reverse operation destination code, turnout information and expected turnout position includes:

[0093] Determine the reverse operation path of the target train according to the train position and the reverse destination code;

[0094] Screen the corresponding turnouts on the reverse operation path of the target train according to the turnout information, and judge whether the screened turnouts are in the expected turnout position;

[0095] When the screened turnout is not in the expected turnout position, issue the corresponding turnout operation command to operate the turnout to the expected turnout position.

[0096] For train A, on the path to the target platform in section G1604, there is only turnout P1602. If turnout P1602 is not in the normal position, the ATS system will issue the normal position operation command for turnout P1602.

[0097] While the turnout is being identified and adjusted, the corresponding Zone Controller (ZC) prohibits C-communication trains outside the corresponding area from entering this area. When it is determined that the target train has come to a complete stop, there are no other vehicles on the path of the target train to the target platform in the reverse running area, and no other trains will intrude into this area, the Zone Controller (ZC) activates the reverse running area where Train A is located.

[0098] Among them, after the Zone Controller (ZC) determines that the reverse running area is activated, it will periodically prompt the ATS system about the activation status of the reverse running area. When the ATS system receives the activation status of the reverse running area from the Zone Controller (ZC), it will prompt the central dispatcher to improve the management efficiency of the reverse running area.

[0099] After activating the reverse running area, in order to further ensure the operation safety of the target train, the following operations are also carried out:

[0100] Determine the reverse running path of the target train according to the train position and the reverse destination code;

[0101] Initiate a reverse locking application for the corresponding section according to the reverse running path;

[0102] Based on the reverse locking application, prohibit the establishment of a forward route including the corresponding section, close the signal machines of the forward open routes including the corresponding section, and lock each reverse sub-route in units of sections one by one;

[0103] When all reverse sub-routes are locked, switch the locking direction of the section where the target train is located;

[0104] When the locking direction of the section where the target train is located after switching is consistent with the reverse running direction, calculate the movement authorization.

[0105] Taking the reverse running control of Train A as an example, after determining that the reverse running area is activated, according to the position of Train A and the reverse running area information in the electronic map, judge the path information of Train A to the target platform, and send the reverse locking application information of Section G1602, Section G1604, and Section G1606 to the Interlocking System (CBI).

[0106] After receiving the reverse locking application information of Section G1602, Section G1604, and Section G1606 from the ZC, the Interlocking System (CBI) prohibits the establishment of all forward routes including Section G1602, Section G1604, and Section G1606, immediately closes all signal machines of the forward open routes including Section G1602, Section G1604, and Section G1606, and locks each reverse sub-route in units of sections one by one. Only when the Interlocking System (CBI) determines that all reverse sub-routes are locked, the Interlocking System (CBI) gives the locking direction information of the corresponding section to the Zone Controller (ZC).

[0107] When the area controller ZC determines that the reverse operation area is activated, the train has come to a complete stop, the on-vehicle controller has completed end-changing, the area controller ZC has not granted movement authority to other trains to enter this section, and the sections downstream to the destination platform have all been reversely locked, the area controller ZC will automatically switch the locking direction of the section where train A is located to be consistent with the direction of the reverse operation area.

[0108] When the area controller ZC determines that the reverse operation area is activated, there are no other vehicles on the path of train A to the destination platform in the reverse operation area, and the section locking direction information given by the interlocking system CBI is consistent with the direction in the reverse operation area information recorded in the electronic map, the area controller ZC calculates the movement authority for train A based on the activated end information of the on-vehicle controller; otherwise, no movement authority is calculated.

[0109] After the movement authority is completed, the target train can be controlled to run to the target platform according to the reverse operation destination code and the movement authority.

[0110] After the target train arrives at the target platform, the corresponding reverse operation area activation application is cancelled;

[0111] When all reverse operation area activation applications of all trains performing reverse operation in the reverse operation area are cancelled, or when it is recognized that there are no trains that need to perform reverse operation in the reverse operation area, all reverse locking applications for the sections in the reverse operation area are cancelled, and the sub-route is unlocked after the sub-route unlocking conditions are met.

[0112] For the area controller ZC, after receiving that the reverse operation area activation application sent by the on-vehicle controller is valid, it should keep the reverse operation area activation application valid until it receives the secondary cancellation command of the reverse operation area activation application issued by the ATS system, and determines that all reverse operation area activation applications of all trains in this reverse operation area have been cancelled or the area controller ZC determines that there are no other vehicles that need to perform reverse operation in this reverse operation area, and then the area controller ZC cancels all section reverse locking applications sent to the interlocking system CBI.

[0113] When the interlocking system CBI determines that the section reverse locking application is invalid and determines that the sub-route unlocking conditions are met, the sub-route is unlocked.

[0114] Considering that there may be multiple trains that need to perform reverse operation in the same reverse operation area, the reverse operation of the corresponding trains is carried out in sequence.

[0115] Specifically, when the number of trains performing reverse operation in the reverse operation area is greater than one, the train closest to the target platform is used as the target train, and the target train is controlled to run to the corresponding target platform and stop;

[0116] After the train closest to the target platform departs from the reverse operation area, reselect the next train operating in reverse as the target train until all trains operating in reverse within the reverse operation area have run to the corresponding target platform.

[0117] After the target train arrives at the target platform, clear the passengers on the target train and judge the forward operation conditions of the target platform.

[0118] When the target platform meets the forward operation conditions, adjust the turnout position of the corresponding section and control the target train to operate forward.

[0119] When the target platform does not meet the forward operation conditions, reset the reverse operation area information and control the target train to run to the next target platform until the platform where the target train is located meets the forward operation conditions.

[0120] Taking the reverse operation control of Train A as an example, referring to Figure 1 the operating line, it can be seen that the platform type of the target platform on section 1604 where Train A stops meets the forward operation conditions, so Train A can be organized to operate normally forward via the reverse position of turnout P1602 - P1604. If the platform type does not meet the forward operation conditions, it is necessary to extend to the next reverse operation area. After the extension, continue to follow the above steps, reset the reverse operation area information, and run in reverse to the next platform until the subsequent normal forward operation of Train A can be guaranteed.

[0121] The data flow of signals, applications, etc. involved in this embodiment is as Figure 3 shown. It can be seen from Figure 3 that the safety protection method for the reverse operation of the train described in this embodiment mainly relies on the execution of signal subsystems such as the ATS system, on-board controller OBC, zone controller ZC, and interlocking system CBI.

[0122] The above-described embodiments are only a preferred solution of the present invention and do not impose any form of limitation on the present invention. There are other variations and modifications without exceeding the technical solutions recorded in the claims.

The safety protection method for the reverse direction operation of a communication train according to claim 1 is characterized in that: Before issuing the reverse run command and reverse run destination code to the target train, the following operations are also performed: Determine the reverse running path of the target train according to the train position and the reverse destination code; Pre-check whether there is a forward route that conflicts with the reverse running path; When there is a forward route that conflicts with the reverse running path, an alarm is issued and the reverse running command and reverse running destination code are refused to be issued.

8. The safety protection method for communication train running in the reverse direction according to claim 1 is characterized in that: Also includes: After the target train arrives at the target platform, the corresponding reverse running area activation application is cancelled; The reverse operation area activation applications of all trains running in the reverse operation area are canceled, or when it is identified that there are no trains that need to run in the reverse operation area, all reverse locking applications for sections in the reverse operation area are canceled, and the sub-route is unlocked after the sub-route unlocking conditions are met.

9. The safety protection method for communication train running in the reverse direction according to claim 1 is characterized in that: Also includes: When the number of trains running in the reverse direction in the reverse running area is greater than one, the train closest to the target platform is taken as the target train, and the target train is controlled to run to the corresponding target platform and stop; After the train closest to the target platform leaves the reverse running area, the next reverse running train is reselected as the target train until all reverse running trains in the reverse running area are controlled to run to the corresponding target platform.

10. The safety protection method for communication train running in the reverse direction according to claim 1 is characterized in that: The method of controlling the target train to run to the corresponding target platform and stop based on the reverse running destination code and the movement authorization also includes: After the target train arrives at the target platform, the target train is cleared and the target platform is judged for positive operation conditions; When the target platform meets the forward running conditions, adjust the switch position of the corresponding section to control the target train to run forward; When the target platform does not meet the forward running conditions, the reverse running area information is reset to control the target train to run to the next target platform until the platform where the target train is located meets the forward running conditions.
