[0002] With the rapid development of rail transit technology and the scale of the driving line network, the attractiveness of rail transit to passengers is continuously increasing, gradually becoming an important mode of public transportation, while the passenger flow is continuously increasing, the operation interval of the line and the full load rate tend to or exceed saturation, which has a certain impact on the comprehensive transport capacity.

[0003] The turnout, as an important part of the signal interlocking system of rail transit, is a key device for arranging routes and realizing route conversion.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0036] In the description of the embodiments of the present invention, it should be noted that the terms "first", "second" and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, a wired communication connection, or a wireless communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention based on the specific circumstances.

[0038] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0039] The following is combined with Figures 1 to 3 This invention describes a route control method for crossover turnout sections according to an embodiment of the present invention.

[0040] In this embodiment of the invention, the crossover turnout section is the track section where the crossover turnout is located. The crossover turnout connects the first track line and the second track line. The crossover turnout includes a first single-action turnout and a second single-action turnout. The first single-action turnout is connected to the first track line, and the second single-action turnout is connected to the second track line.

[0041] Understandably, when a train enters the crossover switch section from the first track, the first single-action switch connects to the first track and is a single-action switch on the route. The second single-action switch connects to the second track and is a single-action switch off the route.

[0042] Among them, the route refers to the path taken by a train, shunting locomotive, or trainset from one location to another.

[0043] In practice, crossover turnouts can be single crossover turnouts or cross-crossing turnouts. Cross-crossing turnouts include the first single crossover turnout and the second single crossover turnout.

[0044] It should be noted that in the circuit design of this embodiment of the invention, the single crossover turnout is treated as two single-action turnouts. The control circuits of the two single-action turnouts are not related to each other, and separate operation commands and turnout status are set for each.

[0045] Take a crossover turnout as an example.

[0046] The first single crossover turnout includes the first single-moving turnout and the second single-moving turnout, and the second single crossover turnout includes the third single-moving turnout and the fourth single-moving turnout.

[0047] The control circuits of the first and second single-acting turnouts are independent of each other, and each has its own separate operating commands and turnout status indication.

[0048] The control circuits of the third and fourth single-acting sub-turns are also independent of each other, and each has its own separate operating commands and turnout status indication.

[0049] The crossover turnout connects the first track and the second track. Specifically, the first single-moving sub-turnout is connected to the first track, the second single-moving sub-turnout is connected to the second track, the third single-moving sub-turnout is connected to the second track, and the fourth single-moving sub-turnout is connected to the second track.

[0050] For example, Figure 2 This is one of the schematic diagrams of the crossover turnout section provided by the present invention, such as... Figure 2 As shown, the first single crossover turnout includes the first single-moving sub-turnout P3503 and the second single-moving sub-turnout P3506, and the second single crossover turnout includes the third single-moving sub-turnout P3505 and the fourth single-moving sub-turnout P3504.

[0051] The first single-acting turnout P3503 and the third single-acting turnout P3505 are connected to the first track where the down-going signal light X3503 is located.

[0052] The second single-acting turnout P3506 and the fourth single-acting turnout P3504 are connected to the second track where the up-going signal light S3506 is located.

[0053] The track sections containing the first single-acting turnout P3503, the second single-acting turnout P3506, the third single-acting turnout P3505, and the fourth single-acting turnout P3504 are crossover turnout track sections.

[0054] Most crossover turnouts in related technologies control the route direction by using the interlocking logic of double-action turnouts.

[0055] by Figure 2 Taking the crossover turnout shown as an example, the relevant technology follows the interlocking logic of double-acting turnouts to handle the routes from X3503 to X3509. The turnout inspection and locking are: (P3501), P3503 / P3506, P3504 / P3505.

[0056] Among them, P3503 / P3506 indicates that the interlocking logic check of double-acting turnouts is performed on P3503 and P3506, P3504 / P3505 indicates that the interlocking logic check of double-acting turnouts is performed on P3504 and P3505, and (P3501) indicates that the interlocking logic check of single-acting turnout is performed on P3501 connected to the crossover turnout.

[0057] The relevant technology also handles the routes from X3503 to X3509 according to the interlocking logic of single-action plus double-action, and the turnout inspection and locking are: (P3501), P3503, [P3506], P3505, [P3504].

[0058] Wherein, [P3506] indicates that the interlocking logic check of the protective turnout is performed on P3506, [P3504] indicates that the interlocking logic check of the protective turnout is performed on P3504, the interlocking logic check of the single-action turnout is performed on P3503, and the interlocking logic check of the single-action turnout is performed on P3505.

[0059] In this embodiment, P3503 and [P3506] indicate that P3503 and P3506 constitute a two-action logic, and P3505 and [P3504] indicate that P3504 and P3505 constitute a two-action logic.

[0060] It should be noted that for double-action turnouts, it is necessary to check that each set of turnouts is in the correct position, and that both are in the correct position or both are in the reverse position. When the turnout is set as a double-action turnout, if a reverse operation is required during turnout positioning, both sets of turnouts should be operated from the correct position to the reverse position. Only after both sets of turnouts have shown the reverse position can the double-action turnout be considered to be in the reverse position. Similarly, the operation from the reverse position to the correct position is also the same.

[0061] When the position status of a certain set of turnouts is missing, the entire double-acting turnout system is considered to be missing its position. In this situation, if a set of turnouts loses its position indication and cannot recover it, then all routes passing through that turnout cannot be processed and must wait for the fault to be resolved, reducing operational efficiency.

[0062] Similarly, since it is set to double-action, the route operation or single operation of both sets of turnouts are simultaneous positioning operation or simultaneous reversing operation. When only one set of turnouts needs to be inspected, the other set of turnouts will also need to be passively operated, which is not flexible enough and increases the number of times the equipment is used.

[0063] In related technologies, crossover turnouts use the interlocking logic of double-action turnouts for route processing. The interlocking logic of double-action turnouts is complex, and the turnout control process for route processing is cumbersome, resulting in low route processing efficiency, affecting the operational capacity of rail transit lines, and reducing overall transport capacity. The following describes a route control method for crossover turnout sections according to an embodiment of the present invention. Under the premise of ensuring safety and controllability, the double-action logic is modified to a single-action plus drive logic. Simultaneously, the turnout section protected in the double-action logic is configured as the main route or the over-limit section of the protected section, improving route processing efficiency and enhancing the operational efficiency of the line.

[0064] Figure 1 This is a flowchart illustrating the route control method for crossover turnout sections provided by the present invention, as shown below. Figure 1 As shown, the route control method for the crossover turnout section of this invention includes steps 110 and 120.

[0065] Step 110: Obtain the status of the first and second turnouts in the crossover turnout section, and perform an over-limit check on the first track section.

[0066] Step 120: If the result of the over-limit inspection in the first track section is that it does not exceed the limit, based on the status of the first turnout and the status of the second turnout, process the route for the train to enter the crossover turnout section from the first track line.

[0067] Specifically, the first turnout status refers to the turnout indication status of the first single-action turnout, the second turnout status refers to the turnout indication status of the second single-action turnout, and the first track section refers to the track section where the second single-action turnout is located.

[0068] The status of a turnout refers to its displayed status in the turnout column of the interlocking table, including statuses such as being in position, reversed, and out of position.

[0069] Taking a crossover turnout as an example.

[0070] The first turnout status includes the turnout indication status of the first single-moving sub-turnout and the third single-moving sub-turnout; the second turnout status includes the turnout indication status of the second single-moving sub-turnout and the fourth single-moving sub-turnout; and the first track section is the track section from the second single-moving sub-turnout to the fourth single-moving sub-turnout.

[0071] Understandably, the first turnout status is used to characterize the turnout representation status of turnouts on the approach route from the first track line into the crossover turnout section, and the second turnout status is used to characterize the turnout representation status of turnouts on the non-approach route.

[0072] Correspondingly, the first track section is the track section where the turnouts on the non-entry route are located.

[0073] In step 110, the status of the first turnout and the status of the second turnout are obtained, and the status of the crossover turnouts on the route and off the route are displayed and operated as single-action turnouts.

[0074] The first track section is checked for exceeding limits, and the track sections where the crossover turnouts on the non-route are located are processed by interlocking logic according to the condition exceeding limits.

[0075] In practical engineering applications, when conducting over-limit checks on the first track section, the axle counters in the crossover turnouts, whether over-limit or non-over-limit, must be checked according to the over-limit axle counter handling method.

[0076] In this embodiment, the first track section where the turnout protected by dual-action logic is located is configured as the over-limit section of the main route or the protected section for over-limit inspection, which can effectively reduce the side impact risk caused by changing from dual-action logic to single-action logic.

[0077] In actual implementation, step 120 includes processing the train route via the first single-action turnout based on the state of the first turnout, and moving the second single-action turnout to the correct position based on the state of the second turnout.

[0078] In this embodiment, the route is processed according to the first turnout status of the first single-action turnout, and at the same time, the second single-action turnout that is not on the route is activated.

[0079] The term "driving handling" refers to the process of moving certain switches that are not on the route to a designated position and locking them during route planning.

[0080] It should be noted that the handling of turnouts is different from that of protective turnouts. Protective turnouts require the route to check their interlocking conditions. The route cannot establish a protective turnout if it is not in the specified protective position.

[0081] The locking and signal opening of the route do not require checking the status of the driving turnout. Even if the driving turnout is not in the specified position during the route arrangement process, the route opening signal can still be established.

[0082] The relevant technology involves crossover switches using the interlocking logic of double-acting switches to handle routes. The interlocking logic of double-acting switches is complex, and the switch control process for handling routes is cumbersome, resulting in low route handling efficiency, affecting the line operation capacity of rail transit, and reducing overall transport capacity.

[0083] In this embodiment of the invention, the crossover turnout is equivalent to a single-action turnout, simplifying the interlocking logic and turnout control process of the crossover turnout section. The double-action logic of the crossover turnout is equivalent to the logic of single-action plus over-limit check. The logic that the turnout on the non-route being driven does not affect the route arrangement if it is not brought to the prescribed position, thereby improving the efficiency of route processing.

[0084] The route control method for crossover turnout sections provided by the present invention obtains the status of the first turnout on the route and the status of the second turnout on the non-route, and performs over-limit checks on the first track section on the non-route. Under the premise of ensuring safety and controllability, it improves the route processing efficiency of crossover turnout sections and enhances the operational efficiency of the line. It is applicable to scenarios of single crossover turnouts and crossover turnouts, and provides better technical support for the integrated design, data generation and product acceptance of newly built lines.

[0085] In some embodiments, if the second single-acting turnout is not in the positioning state and the track relay of the first track section is dropped, the route via the first single-acting turnout is controlled to not be locked, or the open signal on the route via the first single-acting turnout is controlled to be closed.

[0086] The second single-acting turnout is not in the positioning state, that is, the second single-acting turnout is in the reverse position or out of position; the track relay of the first track section is down, indicating that the first track section is currently occupied or in a fault state.

[0087] It should be noted that the route application process is divided into a route locking phase and a signal opening phase. When applying for a route, the route locking conditions are first checked according to the turnout status. If the route locking conditions are met, the designated route is locked. After the route is locked, it is then determined whether the signal opening conditions are met. If they are met, the signal is opened. If not, the signal is opened after the signal opening conditions are met. If the route locking conditions are not met, the route application fails.

[0088] In this embodiment, the second single-acting turnout is not in the positioning state, and the track relay of the first track section is dropped, resulting in a failed route processing. The route positioned via the first single-acting turnout is not allowed to be locked, or the already opened signal is immediately closed.

[0089] The following section uses a crossover turnout as an example to introduce a specific implementation.

[0090] like Figure 2 As shown, for the route from X3503 to X3509, the turnout inspection and locking are as follows: (P3501), P3503, {P3506}, P3505, {P3504}, and the over-limit sections are added: <(P3504)>DG3508, <(P3506)>DG3508.

[0091] Wherein, (P3501) indicates that the interlocking logic check of single-action turnout is performed on P3501 connected to the crossover turnout, the interlocking logic check of single-action turnout is performed on P3503, the interlocking logic check of single-action turnout is performed on P3505, {P3506} indicates that the interlocking logic check of driving turnout is performed on P3506, and {P3504} indicates that the interlocking logic check of driving turnout is performed on P3504.

[0092] <(P3504)>DG3508 and <(P3506)>DG3508 indicate that an over-limit check is being performed on the DG3508 track section where P3504 and P3506 are located.

[0093] In this embodiment, when designing the interlocking table, the other action of P3506 and P3504 on the non-route is processed in the turnout column, and the DG3508 track section on the non-route is processed according to the condition exceeding the limit for interlocking logic.

[0094] In practical engineering applications, when performing over-limit checks on the first track section, the axle counters in the crossover turnouts, whether over-limit or not, must be checked according to the over-limit axle counter processing method. In this embodiment, the interlocking software processing logic is adapted through at least the following three aspects:

[0095] Firstly, P3503, P3504, P3505, and P3506 will be operated and their status displayed independently as single-action turnouts.

[0096] Secondly, take the route via P3503 and P3505 to bring P3504 and P3506 to their positions.

[0097] Thirdly, when P3504 and P3506 are not in the positioning state, if the DG3508-GJ track relay falls, the path positioned via P3503 and P3505 is not allowed to be locked, and the open signal will be immediately closed.

[0098] In some embodiments, the route control method for crossover turnout sections further includes: sending the occupancy status of a first track section to an area controller on the first track line, wherein the occupancy status of the first track section is used by the area controller to determine movement authorization.

[0099] In this embodiment, the area controller uses the first track section undergoing over-limit checks as a condition for calculating the movement authorization of the train, and determines the movement authorization based on the occupancy status of the first track section.

[0100] In actual operation, the first track section is the track section where the second single-acting turnout is located. When the second single-acting turnout is not in the positioning state and the track relay of the first track section is dropped, it indicates that the occupancy status of the first track section is abnormal or faulty. The occupancy status of the first track section is sent to the area controller, which instructs the area controller to revert the movement authorization back to the entrance axle of the first track section.

[0101] For example, such as Figure 2 As shown, when P3504 and P3506 are not in the positioning state, if DG3508-GJ falls, the area controller on the first track line will retract the movement authorization to the entrance axle of the section corresponding to DG3508.

[0102] It should be noted that step 110 involves an over-limit check on the first track section, including:

[0103] Conduct an over-limit inspection of the first track section;

[0104] And / or, perform a locking over-limit check on the first track section.

[0105] In practice, depending on the actual operating scenario, the first track section can be checked for over-limit behavior by checking for over-limit occupancy, over-limit locking, or both simultaneously, to reduce the risk of side impact.

[0106] The following analysis of train operation scenarios uses the example of conducting over-limit checks.

[0107] The axle counters on the crossover switches are either oversized or non-oversized. Figure 3 This is the second schematic diagram of the crossover turnout section provided by the present invention, as shown below. Figure 3 As shown, when the route ending at signal S1 is locked, the train route from signal S2 to signal S4 is processed.

[0108] In this embodiment, the route with signal S1 as the terminal has an external protection section 1DG. The length of the 1DG section meets the length of the protection section and is greater than the length of the protection section under the maximum slope.

[0109] When signal S2 is open, and train routes from signal S2 to signal S4 are being processed, one of the following four scenarios may occur:

[0110] Firstly, when the onboard equipment is in Continuous Train Control (ITC) / Point-to-Point Train Control (CTC) mode, the 1DG section is a protected section of the route with the S1 signal as the terminal, and the JZ01 axle counter does not exceed the limit. At this time, the range protected by the onboard ATP of the train on the route with the S1 signal as the terminal will not exceed the JZ01 axle counter, and there is no safety risk.

[0111] Secondly, when the onboard equipment is in ITC / CTC mode, the 1DG section is a protected section of the route with S1 signal as the terminal, and the JZ01 axle count exceeds the limit, there is no safety risk when the danger point protected by the train's onboard ATP on the route with S1 signal as the terminal does not exceed the limit with the route starting from S2 signal.

[0112] Thirdly, when the onboard equipment is in ITC / CTC mode, the 1DG section is a protected section of the route with the S1 signal as the terminal, and the JZ01 axle count exceeds the limit. At this time, when the danger point protected by the train's onboard ATP on the route with the S1 signal as the terminal constitutes an over-limit with the route starting from the S2 signal, there is a safety risk of side impact.

[0113] Fourth, when the onboard equipment is disconnected or the train is in controlled manual driving mode (RM), the 1DG section is a protected section of the route terminated by the S1 signal. When a train enters the 1DG section, it may collide with a train traveling on the route between the S2 and S4 signals, posing a safety risk. It is necessary to consider providing safe application conditions to the operators.

[0114] In this embodiment, simply performing an over-limit occupancy check may pose a safety risk of side impact. Therefore, an over-limit locking check can be added to avoid the safety risk of side impact.

[0115] It should be noted that, based on the location of the over-limit axle and the danger point, and depending on the actual operating scenario, it is determined whether to conduct an over-limit occupancy check or a lock-up check on the first track section that is not on the route.

[0116] The following describes the route control device for the crossover turnout section provided in the embodiments of the present invention. The route control device for the crossover turnout section described below and the route control method for the crossover turnout section described above can be referred to in correspondence with each other.

[0117] Figure 4 This is a schematic diagram of the route control device for the crossover turnout section provided by the present invention; as shown. Figure 4 As shown, the route control device for the crossover turnout section provided in this embodiment of the invention includes:

[0118] The acquisition module 410 is used to acquire the status of the first turnout and the second turnout in the crossover turnout section, and to perform an over-limit check on the first track section.
