Description

Technical Field

[0001] The present invention relates to the technical field of rail transit control, and in particular to a system and method for processing an automatic train reversal route based on an interlocking system. Background Art

[0002] In rail transit systems, to achieve flexible bus-like operations, reversing lines are set up at the ends or intermediate stations of the line to allow trains to quickly and safely complete line changes or temporarily store spare trains to meet the line's capacity requirements. However, whether it is an urban line or a subway line, the time it takes for trains to reversing has affected the line's operational efficiency. In particular, in the current situation of train-to-ground communication failures or special weather conditions (on ground sections), the dispatching center delegates dispatching authority to the station, and the station dispatcher manually arranges all train routes within the station to command the operation of trains within the jurisdiction. Especially in stations or lines with relatively dense traffic, when the above situation occurs, the number of trains in the station's control area will increase sharply, resulting in a decrease in the overall train reversing efficiency and affecting the traffic capacity of the entire line. Summary of the Invention

[0003] The purpose of the present invention is to provide a train automatic reversal route processing system and method based on an interlocking system. Based on the interlocking route control mode and interlocking safety logic of the existing interlocking system, without changing the existing interlocking safety logic, the station interlocking system adds an automatic reversal function for a specific reversal path, so as to solve the problem of improving the overall train reversal efficiency and the traffic capacity of the entire line when the line is converted to station control / emergency station control mode or the train is degraded.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] In the first aspect, the present invention provides a train automatic reversal route processing system based on an interlocking system, comprising: an automatic reversal setting module and an automatic route selection module arranged in the interlocking system; the interlocking system is provided with an automatic reversal route library corresponding to the station, and the automatic reversal route library includes at least one route combination; the automatic reversal setting module is connected to the interlocking system; the automatic reversal setting module is used to set and judge whether the automatic reversal attribute is set successfully according to the received automatic reversal command in the station control / emergency station control mode; the automatic route selection module is connected to the automatic reversal setting module; the automatic route selection module is used to arrange the route combination required for the train reversal according to the train position and route arrangement conditions after the automatic reversal attribute is set successfully; the interlocking system is used to control the train to realize reversal and line change and end change operations on this route combination according to the route combination arranged by the automatic route selection module. Optionally, it also includes: an automatic reversal cancellation module arranged in the interlocking system,

[0006] The automatic return cancellation module is connected to the automatic route selection module, and is used to cancel the automatic return attribute set by the automatic return setting module when the station has central control and the train automatic return function (including unmanned automatic return) is repaired or restored, so that the station can be restored from the station control / emergency station control mode to the central control mode.

[0007] Optionally, each station includes multiple independent automatic reversing access depots.

[0008] Optionally, each route combination is one of the combinations of all return routes and basic routes of the station.

[0009] Optionally, the automatic reversal setting module is specifically connected to a human-machine interface of the interlocking system, the human-machine interface being used to effectively control route combinations and display the status of station yard signal equipment, and an automatic reversal operation button is provided on the human-machine interface. The automatic reversal operation button is connected to the automatic reversal setting module and is used to trigger the generation and transmission of the automatic reversal command to the automatic reversal setting module.

[0010] Optionally, the automatic return inspection conditions include at least: failure to carry out the overall guidance locking, failure to carry out the automatic return cancellation procedure, the return inspection conditions being met, the hostile approach not being established, the automatic return hostile conditions not being met, the hostile automatic approach not being carried out, the hostile return not being carried out, and failure to carry out the overall cancellation or overall release procedures.

[0011] If any of the automatic return check conditions cannot be met, the human-computer interaction interface prompts that the automatic return attribute setting has failed, and prompts the reason for the setting failure.

[0012] If all conditions in the automatic return check conditions are met and the automatic return attribute is set successfully, the automatic return operation button changes color.

[0013] Optionally, the automatic route selection module first selects the reversing route required for the train to turn around, and the interlocking system locks all the reversing sections corresponding to the reversing route. After the train passes through the reversing route in sequence and stops in the reversing section, all the reversing sections corresponding to the reversing route are unlocked in sequence as the train passes, and another basic route is automatically arranged according to the interlocking relationship between the routes in the automatic reversing route library.

[0014] Optionally, the arrangement route conditions include basic route processing conditions and return route processing conditions;

[0015] Among them, the conditions for handling the reversing route include at least: the reversing area is idle, all sections of the route are idle, the permission signal is not open, the reverse overlapping hostile route is not handled, the signal blockade is not handled, the switch is in the correct position or unlocked state, the protective switch is in the correct position or unlocked state, the oncoming hostile route is not established, and the starting terminal of the reversing route is not energized; when all the conditions for handling the reversing route are met, the reversing route is handled.

[0016] The basic route processing conditions include at least: the return area is occupied, the permission signal is not open, the reverse overlapping hostile route is not processed, the signal is not blocked, the switch position is correct or unlocked, the protective switch position is correct or unlocked, the oncoming hostile route is not established, and the basic route starting terminal is not energized.

[0017] When all the conditions for the basic route are met, the basic route will be processed.

[0018] Optionally, the interlocking system is further configured to close the forward signal of the reversing route after processing the basic route or the reversing route. The basic route or the reversing route is established and locked, and then the route signal of the reversing route or the basic route is opened. After the train passes through the reversing route or the basic route according to the route signal, the locked reversing sections in the reversing route or the basic route are unlocked in sequence after being occupied and cleared by the train; the automatic reversing cancellation module continuously checks whether the automatic reversing attribute is canceled. If it is canceled, the automatic route selection module of the station becomes invalid; if it is not canceled, the automatic route selection module continues to the next route arrangement cycle.

[0019] Optionally, the automatic return cancellation module makes a judgment based on the following cancellation conditions: the cancellation judgment conditions at least include: when the automatic return attribute has been set, the automatic return cancellation or the total cancellation or total release procedure is processed; when any of the cancellation judgment conditions is met, the automatic return cancellation module cancels the automatic return attribute, otherwise the automatic return attribute remains until the next arrangement route cycle.

[0020] When none of the conditions in the cancellation judgment condition are met, the automatic return attribute is maintained to the next arrangement route cycle.

[0021] Optionally, the automatic reversal attribute is canceled by the automatic reversal operation button or by a sub-route in the route combination; the reversal route and the basic route included in the route combination are both the sub-route;

[0022] Among them, when the automatic return attribute is canceled through the automatic return operation button, only the automatic return attribute is canceled, and the status of the sub-route in the current route combination remains unchanged. The cancellation of this automatic return attribute can also be canceled during train operation, and has no effect on the unlocking of the sub-route.

[0023] When the automatic return attribute is canceled through a sub-route, if any sub-route in the current route combination is canceled or released by the total person, the corresponding automatic return attribute is also canceled when the sub-route is canceled or released by the total person, and the color mark of the automatic return operation button changes again.

[0024] In the second aspect, the present invention also provides a method for processing a train automatic reversal route, which is implemented using the train automatic reversal route processing system based on the interlocking system as described above. The method includes: when the station train dispatching is changed from the central mode to the station control / emergency station control mode, the automatic reversal setting module is used to set the automatic reversal attribute based on the received automatic reversal command and the automatic reversal inspection conditions and determine whether the automatic reversal attribute is set successfully.

[0025] After the automatic reversal attribute is successfully set, the route combination required for the train reversal is arranged according to the route arrangement conditions set by the automatic route selection module.

[0026] The interlocking system controls the train to perform reversing, switching and end-changing operations on the route combination arranged by the automatic route selection module.

[0027] Optionally, when the automatic turnback function (ATB) of the train is restored or the train scheduling authority meets the central control requirements, the automatic turnback attribute set by the automatic turnback setting module is canceled through the automatic turnback cancellation module to restore the station from station control / emergency station control mode to central control mode.

[0028] Compared with the prior art, the present invention has at least one of the following technical effects:

[0029] The efficiency of train reversal can be improved. The train runs strictly in accordance with the movement authorization signal or signal display of the ground signal system. The current ATB function has a certain delay in triggering the route when the train turns around. The next route can only be automatically processed after the locomotive has completed its U-turn. This will cause the train reversal operation interval to be too long. The automatic reversal function mentioned in the present invention sends a trigger command when the train has completely entered the reversing track and has not yet changed the locomotive head. After receiving the command, the interlocking system will immediately process the route. After the train has completed its U-turn, the route has already been prepared and the train can be pulled out immediately, which is equivalent to saving the time for switch conversion and route processing.

[0030] It can reduce the workload of station attendants and reduce human errors. The automatic return function can automatically select and arrange the pull-in / pull-out route according to the train position, automatically unlock the pull-in / pull-out route after the train passes the route, and automatically arrange the pull-out / pull-in when the relevant conditions are met. This allows the train route to be dynamically controlled according to the train's movement, significantly reducing the workload of station attendants who repeatedly arrange the route and the probability of errors.

[0031] The automatic reversal button is easy to operate and flexible in application. In station control / emergency station control mode, the automatic reversal button can be set and canceled at any time according to operational needs to avoid train backlogs caused by slow manual response. The optional automatic reversal function eliminates the complexity of repeated manual route confirmation in station control mode and improves operational flexibility. It is applicable to trains based on communication-based train control systems and backup trains.

[0032] The setting and cancellation of the automatic return function does not affect the existing signal closing timing and lock check control logic, does not reduce the safety of the existing signal control logic, and ensures driving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is a further detailed description of the train automatic reversal route processing system and method based on the interlocking system proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiment of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the drawings. It should be noted that the structure, proportion, size, etc. shown in the drawings of this specification are only used to match the content disclosed in the specification, so that people familiar with this technology can understand and read them, and are not used to limit the implementation conditions of the present invention. Therefore, they have no technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0039] In rail transit systems, reversing lines are installed at both ends or intermediate stations of train lines to achieve bus-like operations. These lines allow trains to quickly and safely change lines or temporarily store spare trains. Trains operate according to plan, and safe and rapid U-turns are completed automatically or manually at designated reversing sections at designated stations. There are two types of train reversals: pre-station reversal and post-station reversal. Post-station reversal: After arriving at the terminal station's passenger platform, passengers are cleared before the train transfers to the departure platform via the reversing line located behind the station. Pre-station reversal: Before entering the station, the train transfers directly to the departure platform via a crossover located in front of the station, allowing passengers to disembark before boarding.

[0040] Whether on urban or subway lines, the time it takes to turn trains around has impacted operational efficiency. For train turnarounds and line switching, most lines have designed an automatic turnaround (ATB) function based on the onboard Automatic Train Operation (ATO) system to improve turnaround efficiency and reduce the workload of dispatchers and drivers. However, this function relies on the Communication Based Train Control (CBTC) system to automatically trigger the route. Failure of any condition during the turnaround process will result in a failure of the automatic turnaround. This is especially true when control authority is delegated to stations due to train downgrades or changes in the operating plan. The automatic turnaround function based on the onboard ATO becomes unavailable, significantly reducing overall train turnaround efficiency on the line. Given the current operational requirement of subway trains running at intervals approaching or even less than 90 seconds during peak hours, the inability to implement automatic turnarounds will result in significant backlogs of subsequent trains.

[0041] The existing CBTC system will have the following problems under the above special circumstances:

[0042] 1. The existing automatic return function has strict requirements on train-ground communication, equipment coordination and other conditions. Its processing logic is complex. If there is a train-ground communication failure or route triggering failure, the automatic return function cannot be realized and manual route arrangement is required, which reduces the overall train return efficiency.

[0043] 2. When a signal system vehicle fails or the dispatching center switches its control mode to station control / emergency station control mode, the route triggering function of the dispatching center fails, resulting in a sharp increase in the workload of handling train turnarounds. The dispatcher not only needs to manually arrange the route, but also needs to communicate with the central dispatcher, drivers, etc. in real time, doubling the labor intensity.

[0044] 3. When a train is downgraded or the operation plan changes, control authority is delegated to the station, that is, when it is switched to station control / emergency station control mode, the dispatcher needs to confirm a large amount of information. If the route is handled incorrectly, the train tracking distance is short and it takes a long time to unlock, affecting the traffic capacity of the entire line and causing delays.

[0045] In order to solve the problem that the above-mentioned existing automatic reversal conditions are not met and the automatic reversal function cannot be realized, it is very necessary to design a method based on the existing CBTC system, specifically based on the interlocking system in the CBTC system, which can still realize the rapid reversal operation of the train after the train is downgraded or the dispatching authority is delegated to the station, that is, in the station control / emergency station control mode.

[0046] like Figure 1 As shown, this embodiment provides a train automatic reversal route processing system based on an interlocking system. It is understood that each station is equipped with an interlocking system. The interlocking system herein has the same basic functions as the interlocking system in the prior art, and will not be described in detail here. The train automatic reversal route processing system based on the interlocking system includes: an automatic reversal setting module 101 and an automatic route selection module 102, which are provided in the interlocking system 10.

[0047] The interlocking system 10 is provided with an automatic reversing route library corresponding to the station (that is, the interlocking system of each station is provided with an automatic reversing route library), and the automatic reversing route library includes at least one route combination; the automatic reversing setting module 101 is connected to the interlocking system 10; the automatic reversing setting module 101 is used to, in the station control / emergency station control mode, according to the received automatic reversing command and in combination with the automatic reversing check condition setting and to determine whether the automatic reversing attribute is set successfully; the automatic route selection module 102 is connected to the automatic reversing setting module 101 connection; the automatic route selection module 102 is used to arrange the route combination required for the train to turn around according to the train position and route arrangement conditions after the automatic return attribute is successfully set; the interlocking system 10 is used to control the train to realize the turnaround and end change operations on this route combination according to the route combination arranged by the automatic route selection module 102, that is, the interlocking system 10 can realize the interlocking function between the switch, route and signal according to the route combination arranged by the automatic route selection module 102, so as to ensure the safe operation of the railway signal system.

[0048] This embodiment is based on the interlocking route control method and interlocking safety logic of the existing interlocking system. Without changing the existing interlocking safety logic, the station interlocking system adds an automatic reversing function for a specific reversing path to solve the problem of improving the overall train reversing efficiency and the traffic capacity of the entire line when the line is switched to station control / emergency station control mode or the train is downgraded.

[0049] Please continue to refer to Figure 1As shown, it also includes: an automatic return cancellation module 103 set in the interlocking system 10, the automatic return cancellation module 103 is connected to the automatic route selection module 102, and is used to cancel the automatic return attribute set by the automatic return setting module 101 when the station has central control and the train automatic return function is repaired or restored, so as to restore the station from the station control / emergency station control mode to the central control mode (dispatching center control mode). The automatic return function of this embodiment, its setting and cancellation does not affect the existing signal closing timing and locking check control logic, does not reduce the safety of the existing signal control logic, and ensures driving safety.

[0050] In this embodiment, each station includes multiple independent automatic reversing route pools (the automatic reversing route pool can be directly formed by using the automatic reversing route combinations specified in the interlocking table of the interlocking system). The station can be the starting or ending station of the line, or it can be a station located in the middle of the line with reversing operations. Each route combination is one of the combinations of all reversing routes and basic routes of the station; specifically, the reversing routes and basic routes in each route combination are all routes in the existing interlocking table of the station.

[0051] It can be understood that each route combination consists of a specific return route and a basic route, and the return / basic route in the route combination is one of the train routes of this station (after the station layout and function are determined, all routes for trains in the station will be designed according to operational requirements and compiled into an interlocking table, which describes all routes of the station and their interlocking relationships, thereby forming the above-mentioned route combination. This is existing technology and will not be repeated here).

[0052] It is understandable that a train needs at least two routes to complete a complete reversal operation: 1. The reversal route (pulling route): the path that the train takes when it runs from a certain section to a specific area to stop and prepare to switch direction; 2. The basic route (pulling route): the path that the train or train takes from the starting signal to the terminal blocking signal. Each station has more than one reversal route. To manage the route combinations that appear in these operations, an independent automatic reversal route library is established to match it one-to-one with the automatic reversal operation buttons in the human-computer interaction interface described below. Each automatic reversal operation button corresponds to a specific reversal route and basic route combination, where any route in the route combination can be called its sub-route.

[0053] In this embodiment, the automatic return setting module 101 is specifically connected to the human-machine interface / man-machine interface (Man Machine Interface, MMI) of the interlocking system 10. Figure 1(not shown) is used to effectively control the route combination and display the status of the station yard signal equipment; an automatic return operation button is provided on the human-computer interaction interface, and the automatic return operation button is connected to the automatic return setting module 101, and is used to trigger the generation and sending of the automatic return command to the automatic return setting module 101.

[0054] In some other embodiments, the human-computer interaction interface may further include an automatic return combination button (see Figure 5 As shown), it is connected to the automatic route selection module 102 and is used to change the color of the selected route combination when the automatic route selection module 102 selects the corresponding route combination, so that the dispatcher can intuitively see the selected route combination and reduce the workload of the dispatcher.

[0055] By adding an automatic reversal button to the human-machine interface, convenient operation is achieved while remaining consistent with existing operating methods. Dispatchers can trigger the corresponding automatic reversal function by combining the "automatic reversal button" and the "automatic reversal combination button." The interlocking system 10 automatically checks the various conditions required for automatic reversal and automatically arranges a designated pull-in / pull-out route based on the train's position. After directing the train to the designated reversal area, it automatically arranges the next pull-out / pull-in route, enabling multiple trains within the station to reversing and changing lines sequentially. This function enables automatic reversal of trains on specific routes within the station, reducing the workload of dispatchers. Specifically, in station control / emergency station control modes, it avoids train backlogs caused by slow manual response. The automatic reversal button can be set and canceled at any time based on operational needs. The optional automatic reversal function eliminates the complexity of repeated manual route confirmation in station control mode, improving operational flexibility. Applicable to both CBTC trains and backup trains, it reduces the workload of dispatchers, reduces human error, and improves train reversal efficiency.

[0056] Specifically, such as Figure 2 As shown, in this embodiment, the automatic return inspection conditions include at least: failure to carry out the guidance general locking, failure to carry out the automatic return cancellation procedure, the return inspection conditions are met, the hostile approach is not established, the automatic return hostile conditions are not met, the hostile automatic approach is not carried out, the hostile return is not carried out, and the general cancellation or general release procedures are not carried out.

[0057] If any of the automatic return check conditions cannot be met, the human-computer interaction interface prompts that the automatic return attribute setting has failed, and the human-computer operation interface operation record prompts the reason for the setting failure.

[0058] If all conditions in the automatic return check conditions are met, the automatic return attribute is set successfully, and the automatic return operation button changes color. For example, when the automatic return attribute is not set, the automatic return operation button is gray. When the automatic return attribute is successfully set, the automatic return operation button changes from gray to yellow, but the present invention is not limited to this.

[0059] That is, to realize the automatic processing of automatic reversal route, at least the safety condition check of the operator's operation of the automatic reversal operation button must be carried out (that is, the specific process of checking each condition in the above-mentioned automatic reversal inspection conditions is judged according to the existing judgment logic, which will not be repeated here). After the conditions are met, the interlocking system 10 can automatically select the route. The train will unlock the route after passing according to the driving permit or signal display, and the train reversal operation (abbreviated as CYCLE) will be carried out in a cycle. When the train plan needs to be changed, the automatic reversal function can be canceled by canceling any sub-route or automatic reversal attribute. In addition, the change of the automatic reversal attribute status can be intuitively fed back to the dispatcher through the color change of the automatic reversal operation button.

[0060] In this embodiment, the automatic route selection module 102 first selects the reversing route required for the train to turn around, and the interlocking system 10 locks all the corresponding reversing sections in the reversing route, allowing the signal to be opened. After the train passes through the reversing route in sequence and stops steadily in the reversing section, all the reversing sections corresponding to the reversing route are unlocked in sequence as the train passes (that is, all reversing sections are unlocked in sequence as the train moves forward and occupies and clears them). The train completely enters the reversing route (reversing track) and automatically arranges another basic route according to the interlocking relationship between the routes in the automatic reversing route library.

[0061] like Figure 3 As shown, in this embodiment, the arrangement route conditions include basic route processing conditions and return route processing conditions;

[0062] Among them, the conditions for handling the reversing route include at least: the reversing area is idle, all sections of the route are idle, the permission signal is not open, the reverse overlapping hostile route is not handled, the signal blockade is not handled, the switch is in the correct position or unlocked state, the protective switch is in the correct position or unlocked state, the oncoming hostile route is not established, and the starting terminal of the reversing route is not energized; when all the conditions for handling the reversing route are met, the reversing route is handled.

[0063] The basic route processing conditions include at least: the return area is occupied, the permission signal is not open, the reverse overlapping hostile route is not processed, the signal is not blocked, the switch position is correct or unlocked, the protective switch position is correct or unlocked, the oncoming hostile route is not established, and the basic route starting terminal is not energized.

[0064] When all the conditions for the basic route are met, the basic route will be processed.

[0065] Please continue to refer to Figure 3 As shown, the interlocking system 10 is also used to close the front signal of the reversing route after processing the basic route or the reversing route, establish and lock the basic route or the reversing route, and then open the route signal of the reversing route or the basic route. After the train runs through the reversing route or the basic route according to the route signal, the locked sections in the reversing route or the basic route are unlocked in sequence after being occupied and cleared by the train; the automatic reversing cancellation module 103 continuously checks whether the automatic reversing attribute is canceled. If canceled, the automatic route selection module 102 becomes invalid, that is, the route in the station is restored to the route manually processed by the dispatcher, which means that the automatic reversing function cannot be realized by the dispatcher on duty manually arranging the route; if not canceled, the automatic route selection module 102 continues to the next route arrangement cycle.

[0066] That is, after the above-mentioned route processing conditions are met, the start and end relay states of the route are set to be energized and attracted, thereby realizing the automatic arrangement of the corresponding route. This route arrangement method is the same as the internal principle of manually arranging routes. The difference is that the route processing conditions of the automatic return are automatically checked by the automatic route selection module 102, eliminating the need for manual confirmation of the conditions for opening the route arrangement signal and the time for manually pressing the button, and also reducing the possibility of wrong route processing due to human error. This route arrangement method is independent of the existing route arrangement method of the existing interlocking system, and adds the conditions for automatically checking the arrangement route. Its route processing safety principle is consistent with the existing manual arrangement method (supplementation or examples are required), does not reduce the safety of the existing signal control logic, and ensures the availability and safety of the system.

[0067] After selecting an approach (either a reversing approach or a basic approach), the approach is locked and the signal is released, and the train proceeds according to the signal display. After the train passes through the approach section, the sections within the route are unlocked in sequence according to the train's running order. This approach is completely consistent with the interlocking logic of existing interlocking systems. The automatic route selection module 102 automatically checks if the conditions for arranging another route are met and automatically arranges the next route, allowing the subsequent train to perform the reversing operation.

[0068] In this embodiment, if Figure 4As shown, the automatic return cancellation module 103 makes a judgment based on the following cancellation conditions: the cancellation judgment conditions at least include: when the automatic return attribute has been set, processing the automatic return cancellation and processing the general cancellation or general release procedures; when any of the cancellation judgment conditions are met, the automatic return attribute is immediately canceled by the automatic return cancellation module 103; otherwise, the automatic return attribute is maintained until the next arrangement route cycle. If none of the conditions included in the cancellation judgment conditions are met, the automatic return attribute is maintained until the next arrangement route cycle.

[0069] Specifically, after the automatic return attribute has been set, when the automatic return is canceled, the automatic return attribute is canceled by the automatic return cancellation module 103, that is, the automatic routing function of the automatic routing module 102 is immediately canceled.

[0070] After the automatic return attribute has been set, when the total cancellation or total release procedure is processed, the automatic return attribute is canceled through the automatic return cancellation module 103, that is, the automatic routing function of the automatic routing module 102 is immediately canceled.

[0071] After the automatic return attribute has been set, when the automatic return is canceled and the total cancellation or total release procedure is carried out, the automatic return attribute is canceled through the automatic return cancellation module 103, that is, the automatic routing function of the automatic route selection module 102 is immediately canceled.

[0072] When the automatic return cancellation is not processed and the general cancellation or general release procedures are not processed, the automatic return attribute will be maintained until the next route arrangement cycle.

[0073] In this embodiment, the automatic return attribute can be canceled through the automatic return operation button or through the sub-route.

[0074] Among them, when the automatic return attribute is canceled through the automatic return operation button, only the automatic return attribute is canceled, and the current sub-route status remains unchanged. The cancellation of this automatic return attribute can also be canceled during train operation, and has no effect on the unlocking of the sub-route.

[0075] When the automatic return attribute is canceled through a sub-route, if any sub-route in the current route combination is canceled or released by the general person, the corresponding automatic return attribute is also canceled when the sub-route is canceled or released by the general person, and the automatic return operation button changes color again. For example, the automatic return operation button returns from yellow to gray. This can avoid the dispatcher from triggering the route again after canceling the route, but the present invention is not limited to this.

[0076] On the second aspect, this embodiment also provides a method for processing a train automatic reversal route, which is implemented using the train automatic reversal route processing system based on the interlocking system as described above. The method includes: when the station dispatching mode is changed from the central mode to the station control / emergency station control mode, the automatic reversal setting module is used to set the automatic reversal attribute based on the received automatic reversal command and the automatic reversal inspection conditions and determine whether the automatic reversal attribute is set successfully.

[0077] After the automatic reversal attribute is successfully set, the route combination required for the train reversal is arranged according to the route arrangement conditions set by the automatic route selection module.

[0078] The interlocking system controls the train to perform reversing, switching and end-changing operations on the route combination arranged by the automatic route selection module.

[0079] That is, the interlocking system arranges the routes according to the automatic route selection module. After the train passes through the routes in the order of the route's driving permit and reaches the planned area, the routes are automatically unlocked in sequence. At this time, the automatic route selection module arranges the next route of the train or the route of the next train, and controls the train to realize the line switching and returning operation.

[0080] In this embodiment, when the automatic return function of the train is restored or the train scheduling authority meets the central control, the automatic return attribute set by the automatic return setting module is canceled by the automatic return cancellation module to restore the station from station control / emergency station control mode to central control mode.

[0081] It is understood that the meaning of the handling guide total lock involved in this article is as follows:

[0082] The main locking system for guide signals is used to open guide signals when the switch is unable to indicate the route and cannot be processed. This locking system is generally divided into zones according to the throat of the station yard, and only all switches in the relevant zone are locked. Station personnel must strictly confirm the relevant situation when using it.

[0083] It is understood that the meaning of the adversarial approach involved in this article is as follows:

[0084] Hostile approaches refer to two or more approaches within a railway station that, if opened simultaneously, could lead to conflicts between trains and rolling stock.

[0085] The Railway Computer Interlocking Technical Specifications stipulate that the following routes are hostile routes. Hostile routes should be checked against each other and should not be opened at the same time;

[0086] Train routes and train routes in opposite directions on the same arrival and departure line;

[0087] Train routes and shunting routes in opposite directions on the same arrival and departure line (including non-route shunting);

[0088] Overlapping train routes in opposite directions within the same throat area;

[0089] Overlapping train routes and shunting routes in opposite or forward directions within the same throat area;

[0090] Overlapping shunting routes in opposite directions within the same throat area;

[0091] When the signal is installed at the insulating joint of the track, it is not allowed to open the approach route at the same time;

[0092] The route for pushing trains to the hump and the route for trains or shunting trains to the same track at the other end (including non-route shunting);

[0093] A route that overlaps with a continued route (excluding the forward train route at the beginning of the continued route).

[0094] The meaning of the automatic return hostile condition in the automatic return check condition not being met is as follows:

[0095] Automatic reentry hostile conditions: automatic reentry routes that conflict with or overlap with automatic reentry routes.

[0096] It is understood that the meaning of the automatic approach involved in this article is as follows:

[0097] Automatic route: that is, the route is automatically passed. When the train route enters this mode, the train route will not be automatically unlocked due to the operation of the train. After the train clears the route, if the signal opening conditions are met, the route start signal can be automatically reopened without the need for the attendant to arrange the route again.

[0098] It is understood that the meaning of the total cancellation or total human release procedures involved in this article is as follows:

[0099] Total cancellation and total human solution are both means of unlocking the route.

[0100] Total unlock: that is, manual unlocking of the route. When the route is manually unlocked and there is a vehicle occupying the approach section, the total cancel command can only turn off the signal but cannot unlock the route. When the duty officer confirms that the route ahead can be unlocked, use this command. After a certain safety countdown, the route that needs to be unlocked can be unlocked.

[0101] Total cancellation: that is, canceling the train route. When there is no train occupying the approaching section, the station attendant and the center attendant will manually cancel the route that needs to be unlocked.

[0102] like Figure 5 As shown, a specific example is given to better understand the above-mentioned train automatic return route processing method.

[0103] The example station is the dispatching console interface of a subway line terminal station. According to operational needs, there are four automatic return depots, namely:

[0104] Automatic return name Approach combination Remark CY1 XC-Z2 / SJ-F2 / XC-Z1 / F1-F2 Fully automatic return CY2 XC-Z1 / F1-F2 CY3 XC-Z2 / SJ-F2 CY4 XJ-F2 / SC-SQ1

[0105] Please continue to refer to Figure 5 As shown, each automatic reversal route combination has a button and route icon. The button comes in three colors: gray indicates unset, yellow indicates set, and red indicates cannot be set. The route icon is consistent with the reversal route combination, allowing you to intuitively see the reversal path. Green indicates set, red indicates cannot be set, and gray indicates can be set.

[0106] When the dispatching mode switches to station control or emergency station control mode, the dispatcher manually arranges the routes within the jurisdiction through the MMI to direct all trains to pass in an orderly manner. Taking the example station, 1G and 2G represent tracks labeled 1G or 2G, respectively. 3G represents the down platform, 4G represents the up platform, and Z1, Z2, Z3, F1, F2, XC, SJ, SC, XJ, and SQ1 represent the signals on the line. To transfer a train from the 3G down platform to the 4G up platform, the dispatcher generally needs to first arrange the return route XC-Z2 (shown by the green solid line). Only after the train stops on the 2G track can the basic route SJ-F2 (shown by the red solid line) be arranged again until the train reaches the 4G up platform.

[0107] For example, the automatic reversing route pool CY3 includes the reversing route XC-Z2 and the basic route SJ-F2. According to the automatic reversing route processing method provided in this embodiment, the dispatcher only needs to set the automatic reversing route pool CY3 function to realize the ground automatic reversing control. The details are as follows:

[0108] When the train is on the 2G track, the XC-Z2 / SJ-F2 icon corresponding to the automatic return combination button is gray. After setting the automatic return route library CY3, the system Figure 2The process shown automatically checks the conditions for automatic reversal. When the conditions are met, the XC-Z2 / SJ-F2 icon corresponding to the automatic reversal combination button turns green and the automatic reversal loop button turns yellow. The interlocking system 10 automatically selects the first arrangement route SJ-F2 as the basic pull-out route. The basic pull-out route SJ-F2 checks: all track sections between the SJ signal and the SC signal are idle (the CBTC mode only checks the first logical section in the SJ signal), the positions of switches 3 / 4 and 5 / 6 are correct or unlocked, the SJ signal permission signal is not open, the 3 / 4 and 5 / 6 switches and the start and end buttons are not blocked, there is no oncoming hostile route XJ-SC route, and no automatic reversal route library (CY4, CY2 and CY1) routes are not processed. The system automatically triggers the processing of the SJ-F2 route.

[0109] When the SJ-F2 approach signal is open, it is also necessary to check the emergency close button on the up platform (for example, a red diamond on the up platform indicates that the emergency close button is pressed, and a hidden one indicates that it is not pressed. Figure 5 (not shown) is not pressed, the up platform screen door is closed and locked (the green horizontal line on the down platform indicates that the screen door is closed and locked, and the green horizontal line on the up platform indicates that the screen door is open. Figure 5 (not shown), the SJ signal's filament is intact and guidance has not been processed. These checks are all checks that can be performed by the interlocking system in the existing technology and will not be repeated here. After the SJ signal is opened, the train sequentially occupies 4-6DG (i.e., the SJ-F2 basic route) and the 4G up platform, stopping at the 4G up platform, thus completing a cycle of the return function. After the train clears 4-6DG, it automatically triggers the processing of the next return route XC-Z2 (automatic return route library CY3). If a train occupies the 3G down platform or the 4G up platform, the train can run according to the outdoor signal display, passing 3-5DG (XC-F1 basic route) and 4-6DG in sequence, and then unlocking in sequence. The train completely enters 2G and clears 4-6DG. The system automatically triggers the processing of the SJ-F2 route. In this way, when the train stops at the Z2 signal (red light) and turns the head, the interlocking system has completed the pull-out route SJ-F2 for the train. In this way, the automatic reversal and line changing operations of multiple trains are completed.

[0110] If the operation plan changes, the dispatcher can cancel the automatic reentry function by simply canceling any sub-routes in XC-Z2 / SJ-F2 or canceling the automatic reentry loop button attribute corresponding to the automatic reentry route library CY3. The method for canceling a route is exactly the same as the existing operation method. Canceling the automatic reentry loop button attribute corresponding to the automatic reentry route library CY3 does not affect the unlocking of the sub-routes included in the existing automatic reentry route library CY3, nor does it cancel the routes that have already been triggered.

[0111] In addition, in order to further improve the system's reversing capability, a fully automatic reversing route library CY1 is set up (the solid line is the priority reversing route). The fully automatic reversing route library CY1 consists of 4 routes (including two reversing route combinations, see the table above). At this time, at the 3G down platform, the train can not only turn back on the 1G track, but also turn back on the 1G track to the 4G up platform.

[0112] When Train 3 on 3G needs to turn around, after the fully automatic turnaround operation is completed, the system first checks whether there are any trains occupying the 1G and 2G tracks. If the 2G and 1G tracks are occupied by Train 2 and Train 1 respectively, Train 2's pull-out route is prioritized. After Train 2 runs from the 2G track to the 4G up platform to pick up passengers and exit the station, Train 1's pull-out route is automatically processed. After Train 1 runs from the 1G track to the 4G up platform and clears the 4-6DG, the system immediately and automatically arranges a pull-in route for the existing Train 3 to the 2G track. At this time, Train 3 has already run to the 2G track to turn around. After Train 1 exits the station and clears the 4G up platform, Train 3's pull-out route is immediately automatically processed. At the same time, the system arranges a pull-in route for the subsequent train to the 1G track. This cycle of alternating turnarounds on the 1G and 2G tracks completes the turnaround, end change, or U-turn operation for all trains at the example station.

[0113] In this embodiment, the automatic route selection module 102 can pre-set and define the train priority route and return route principles as needed to meet the operational needs of various trains.

[0114] In summary, the CYCLE function based on the interlocking in this embodiment must be able to meet the needs of trains in CBTC mode as well as trains in backup mode. In order to meet the availability and safety of the system, the automatic reversal function must meet the following requirements: In CBTC and backup modes, after the automatic reversal operation is carried out, the interlocking system should control the processing of the sub-routes included in the reversal cycle command in sequence according to the automatic reversal command and after checking that the relevant conditions are met (the turnout position is correct, no hostile routes are established, and all sections are idle (including restricted sections)). The corresponding routes are automatically unlocked and triggered as the train moves. In CBTC and backup modes, if the relevant routes already exist, the route status remains unchanged after the automatic reversal route cycle attribute is set. In CBTC and backup modes, after the automatic reversal function is canceled through the automatic reversal cycle button, the interlocking system cancels the automatic reversal cycle route attribute, but the route that has been processed will not be canceled. The route is automatically unlocked when the train runs or unlocked after the route cancellation operation is carried out. In CBTC and backup modes, after canceling a sub-route, the interlocking system simultaneously cancels the automatic reversal attribute associated with that route. After executing and canceling the automatic reversal operation, the interface displays an automatic reversal valid indicator and a sound reminder. This embodiment, based on the existing interlocking route control method and interlocking safety logic, adds an automatic reversal function to specific reversal sections at stations without changing the existing safety logic. This addresses the high workload of station dispatchers when the line switches to station control / emergency station control mode or when trains are downgraded.
