[0002] In the railway signaling system, in order to ensure the safe operation of trains, it is necessary to control the train's running path through interlocking (Computer based interlocking, CI).

[0003] To ensure safe and efficient operation of non-communication-based train automatic control systems (CBTC), it's often necessary to control physical sections of the route. For example, unlocking a physical section typically uses a three-point unlocking principle: if the previous state of the physical section to be unlocked was occupied, the current state is idle, and the next physical section to be unlocked is occupied, then CI controls the unlocking of the physical section to be unlocked.

[0004] However, in the CBTC operation mode, considering that the route includes not only physical sections but also logical sections, if the above-mentioned physical section control principle is still adopted, logical errors will occur in the physical section control, making it impossible to accurately perform physical section control.

[0027] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] In the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. A and B can be singular or plural. In the text description of this application, the character " / " generally indicates that the associated objects are in an "or" relationship.

[0029] The physical segment control method provided in the embodiment of the present application can be adapted to the unlocking control scenario of the physical segment of the route. Before introducing the physical segment control method provided in the embodiment of the present application, the terms involved are explained first: Interlocking CI is a key part of the subway signaling system. Its main function is to establish the mutual constraint relationship between signals, switches and routes through technical means. It uses a two-by-two-take-two safety computer platform to realize the correct interlocking constraint relationship between station equipment, and select routes for trains running in its control area, thereby ensuring the safety of subway operation, coordinating train operations and improving transportation efficiency.

[0030] The Zone Controller (ZC) is a core component of the CBTC-based signaling system and is part of the ground equipment. A line is divided into several control zones, each managed by a Zone Controller. Within its assigned zone, the ZC is responsible for providing movement authorities (MAs) to communication trains, informing them of the maximum distance they are permitted to travel.

[0031] A physical segment is a closed area encompassed by adjacent axle counting points. A logical segment logically divides the axle counting segment into several equal segments. Each segment is called a logical segment, and each logical segment represents a possible current train location. A logical segment is the smallest segment in the CBTC operating mode.

[0032] Route processing is when the interlocking receives the route processing command from the upper computer, selects the pending route and performs a consistency check on the route selection. After the check is passed, the route is locked and the permission signal is released. The train enters the route according to the permission signal.

[0033] Cross-pressure means that when the interlocking receives the cross-pressure signal sent by the ground ZC system, the signal machine at the beginning of the route is controlled to be closed.

[0034] Approach unlocking means that after a train enters a locked approach, the physical sections within the route should be automatically unlocked in sections as the train moves. Each physical section (excluding the first physical section within the route) will automatically unlock after a certain delay if the three-point unlocking principle is met. If the first physical section of the route is cleared and the next physical section is occupied, the route's starting signal will automatically unlock after a certain delay after the train enters and the signal is normally closed.

[0035] Taking the unlocking control scenario of the route physical section under the CBTC operation mode as an example, in order to ensure the safe and efficient operation of non-communication trains, it is usually necessary to set up control of the route physical section. Assume that the route S1-S2 contains two physical sections, namely the first physical section P1 and the second physical section P2, wherein the first physical section P1 contains four logical sections, namely the first logical section P1_A, the second logical section P1_B, the third logical section P1_C and the fourth logical section P1_D. For example, see Figure 1 As shown, Figure 1 A schematic diagram of the operation of the leading and following vehicles in a CBTC operation mode provided in an embodiment of the present application Figure 1 The preceding vehicle is vehicle 1, and the following vehicle is vehicle 2. Vehicles 1 and 2 are tracking each other. When vehicle 1 enters route S1-S2, the zone controller sends a cross-pressure signal to the interlocking system. Upon receiving the cross-pressure signal, the interlocking system closes the route start signal S1, and the route status changes from near-open to near-locked. At this point, the previous historical status of the first physical segment P1 is idle, and the current status is occupied. The current status of the second physical segment P2 is idle.

[0036] Car 1 continues to run. If car 1 has cleared the first logical section P1_A of route S1-S2, car 2 can trigger the route again. For example, see Figure 2 As shown, Figure 2 A schematic diagram of the operation of the leading and following vehicles in a CBTC operation mode provided in an embodiment of the present application Figure 2 The route status changes from near-locked to near-open. At this point, the previous historical status of the first physical segment P1 was idle, and the current status is occupied. The current status of the first logical segment P1_A is idle, and the current status of the second physical segment P2 is idle.

[0037] If the car 1 continues to move forward, when the car 1 clears the first physical segment P1, for example, see Figure 3 As shown, Figure 3 A schematic diagram of the operation of the leading and following vehicles in a CBTC operation mode provided in an embodiment of the present application Figure 3 At this time, the previous historical state of the first physical segment P1 is occupied, the current state is idle, and the current state of the second physical segment P2 is occupied.

[0038] If vehicle 2 approaches the route start signal S1, when the area control detects that vehicle 2 has safely entered the first physical section S1, the area controller will send a cross-pressure signal to the interlocking; correspondingly, after receiving the cross-pressure signal, the interlocking will control the route start signal S1 to close.

[0039] In this case, if car 1 occupies the second physical segment P2, see Figure 4 As shown, Figure 4 A schematic diagram of the operation of the leading and following vehicles in a CBTC operation mode provided in an embodiment of the present application Figure 4 , the route status changes from nearly open to nearly locked. At this time, the previous historical status of the first physical section P1 is occupied, the current status is idle, and the current status of the second physical section P2 is occupied, then the control judgment of the first physical section P1 is entered. When the previous historical status of the first physical section P1 is occupied, the current status is idle, and the current status of the second physical section P2 is occupied, combined with Figure 4 It can be seen that the three-point unlocking principle is currently met, and the interlocking control first physical section P1 is unlocked.

[0040] If car 1 has cleared the second physical segment P2, see Figure 5 As shown, Figure 5 A schematic diagram of the operation of the leading and following vehicles in a CBTC operation mode provided in an embodiment of the present application Figure 5 The route status changes from nearly open to nearly locked. At this point, the first physical segment P1 is previously occupied and currently idle. The second physical segment P2 is also idle. The interlocking system considers car 1 lost and sets the first physical segment P1 to a fault-locked state, placing the following car in degraded mode.

[0041] Combined with the above Figure 4 or Figure 5 As shown in the figure, there may be a situation that although the area controller detects that the safety envelope of car 2 enters the first physical section S1 and sends a cross-pressure signal to the interlocking, due to the existence of time difference, in the actual scenario, car 2 does not enter the first physical section S1. If the interlocking controls the route start signal S1 to close based on the cross-pressure signal of car 2 and enters the control judgment of the first physical section P1, Figure 4 For example, the interlock will mistakenly control the first physical section to unlock, or Figure 5As shown, the interlocking will mistakenly control the first physical section P1 to be set to the fault lock state and control the following vehicle to enter the degraded mode. Therefore, the interlocking will mistakenly enter the control logic of the first physical section P1, resulting in a logical error in the control of the first physical section, making it impossible to accurately perform physical section control.

[0042] In order to solve the problem in the prior art that physical sections cannot be accurately controlled in the CBTC operation mode, thereby improving the accuracy of physical section control, the present application proposes a method for controlling physical sections of an approach route. When the leading vehicle has cleared the first logical section in the first physical section of the approach route and the following vehicle is handling the approach route, the historical state of the first physical section and the current state of the first physical section are obtained based on the received cross-pressure signal of the following vehicle; when the historical state of the first physical section is an occupied state and the current state of the first physical section is an idle state, the historical state of the first logical section and the current state of the first logical section are obtained. ; and based on the historical state of the first logical segment and the current state of the first logical segment, the first physical segment is controlled. In this way, when the historical state of the first physical segment is the occupied state and the current state of the first physical segment is the idle state, the first physical segment is controlled together with the historical state of the first logical segment and the current state of the first logical segment. This fully takes into account the influence of the historical state and the current state of the first logical segment on the physical segment control, and can effectively solve the problem in the prior art that the physical segment control cannot be accurately performed in the CBTC operation mode, thereby improving the accuracy of the physical segment control.

[0043] It can be understood that the executor of this method can be an interlocking, specially set access physical section unlocking control device, computer or server and other electronic equipment, or it can be an access physical section control device set in the electronic equipment. The access physical section control device can be implemented by software, hardware or a combination of the two, and can be specifically set according to actual needs.

[0044] The following specific embodiments will be used to describe the route physical segment control method provided by this application in detail. It is understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0045] Figure 6 This is a flow chart of a method for controlling physical sections of a route provided in an embodiment of the present application. For example, see Figure 6 As shown, the route physical section control method may include: S601. When the leading vehicle has cleared the first logical segment in the first physical segment of the route and the following vehicle is processing the route, obtain the historical status of the first physical segment and the current status of the first physical segment based on the received cross-pressure signal of the following vehicle.

[0046] The first physical segment is the first physical segment in the route, and the first logical segment is the first logical segment in the first physical segment.

[0047] For example, in an embodiment of the present application, when obtaining the historical state of the first physical section and the current state of the first physical section based on the received cross-pressure signal of the following vehicle, the starting signal of the route can be controlled to be closed based on the received cross-pressure signal of the following vehicle; and when the starting signal is closed, the historical state of the first physical section and the current state of the first physical section are obtained.

[0048] The current state of the first physical segment is determined based on the collected axle counter occupancy state and the code bit state of the logical segment in the first physical segment sent by the zone controller.

[0049] For example, when determining the current state of the first physical segment based on the collected axle counter occupancy state and the code bit state of the logical segment in the first physical segment sent by the area controller, if the current state of the first physical segment determined based on the collected axle counter occupancy state is consistent with the current state of the first physical segment determined based on the code bit state, for example, if the current state of the first physical segment determined based on the collected axle counter occupancy state and the current state of the first physical segment determined based on the code bit state are both idle states, then the current state of the first physical segment is determined to be an idle state; if the current state of the first physical segment determined based on the collected axle counter occupancy state and the current state of the first physical segment determined based on the code bit state are both occupied states, then the current state of the first physical segment is determined to be an occupied state.

[0050] If the current state of the first physical segment determined based on the collected axle counter occupancy state is inconsistent with the current state of the first physical segment determined based on the code bit state, the current state of the first physical segment is determined to be an idle state. For example, if the current state of the first physical segment determined based on the collected axle counter occupancy state is an idle state, and the current state of the first physical segment determined based on the code bit state is an occupied state, the current state of the first physical segment is determined to be an idle state; if the current state of the first physical segment determined based on the collected axle counter occupancy state is an occupied state, and the current state of the first physical segment determined based on the code bit state is an idle state, the current state of the first physical segment is determined to be an idle state.

[0051] S602: When the historical state of the first physical segment is occupied and the current state of the first physical segment is idle, obtain the historical state of the first logical segment and the current state of the first logical segment.

[0052] In order to control the first physical segment together with the historical state of the first logical segment and the current state of the first logical segment, and fully consider the influence of the historical state and the current state of the first logical segment on the control of the physical segment, in an embodiment of the present application, when the historical state of the first physical segment is the occupied state and the current state of the first physical segment is the idle state, it is not necessary to obtain the current state of the second physical segment first. Instead, by obtaining the historical state of the first logical segment and the current state of the first logical segment, and combining the historical state of the first logical segment and the current state of the first logical segment, the first physical segment is controlled together, that is, executing the following S603. This can effectively solve the problem in the prior art that the physical segment control cannot be accurately performed in the CBTC operation mode, thereby improving the accuracy of the physical segment control.

[0053] S603: Control the first physical segment based on the historical state of the first logical segment and the current state of the first logical segment.

[0054] It can be seen that in the embodiment of the present application, when the leading vehicle has cleared the first logical segment in the first physical segment of the route and the following vehicle is processing the route, the historical state of the first physical segment and the current state of the first physical segment are obtained based on the received cross-pressure signal of the following vehicle; when the historical state of the first physical segment is the occupied state and the current state of the first physical segment is the idle state, the historical state of the first logical segment and the current state of the first logical segment are obtained; and based on the historical state of the first logical segment and the current state of the first logical segment, the first physical segment is controlled. In this way, when the historical state of the first physical segment is the occupied state and the current state of the first physical segment is the idle state, the first physical segment is controlled together with the historical state of the first logical segment and the current state of the first logical segment, which fully takes into account the influence of the historical state and the current state of the first logical segment on the physical segment control, and can effectively solve the problem in the prior art that the physical segment control cannot be accurately performed in the CBTC operation mode, thereby improving the accuracy of the physical segment control.

[0055] Based on the above Figure 6In the illustrated embodiment, for example, before executing step S601 to obtain the historical status and current status of the first physical segment based on the received cross-pressure signal from the following vehicle, if it is detected that the preceding vehicle has cleared the first logical segment, that is, if the preceding vehicle has cleared the first logical segment, the historical status of the first logical segment can be updated to occupied, and the current status to idle. This allows the following vehicle to pre-update the previous occupied status of the first logical segment and the current status to idle when the starting signal is opened. This allows the following vehicle to clear the previous occupied status after the preceding vehicle passed through the first logical segment when the following vehicle crosses the starting signal. Even if the following vehicle's rear wheel pair does not press into the first physical segment in the next cycle, the first physical segment will not be incorrectly unlocked or locked due to the occupation or idleness of the second physical segment. This fully considers the impact of the historical and current status of the first logical segment on physical segment control, effectively resolving the existing issue of inaccurate physical segment control in CBTC operation mode, thereby improving the accuracy of physical segment control.

[0056] Based on any of the above embodiments, for example, in the above S603, based on the historical state of the first logical segment and the current state of the first logical segment, the specific implementation of unlocking the first physical segment can be referred to below. Figure 7 The embodiment shown.

[0057] Figure 7 A flowchart of a method for unlocking a first physical segment based on a historical state of the first logical segment and a current state of the first logical segment is provided in an embodiment of the present application. The method may include: S701. When the historical state of the first logical segment is occupied and the current state of the first logical segment is idle, obtain the current state of the second physical segment of the route.

[0058] For example, when obtaining the current status of the second physical section of the route, the current status of the second physical section of the route can be obtained through track circuit detection; the current status of the second physical section of the route can be obtained through transponder communication; or the current status of the second physical section of the route can be obtained through signal status, etc. The specific settings can be made according to actual needs.

[0059] S702: Control the first physical segment based on the current state of the second physical segment.

[0060] For example, in an embodiment of the present application, when controlling the first physical segment based on the current state of the second physical segment, if the current state of the second physical segment is occupied, the first physical segment is unlocked. This effectively resolves the issue of the first physical segment being incorrectly unlocked due to the second physical segment being occupied. If the current state of the second physical segment is idle, the first physical segment is set to a fault-locked state; and in this fault-locked state, the following vehicle is controlled to enter a degraded mode. This effectively resolves the issue of fault-locked status due to the idleness of the second physical segment, allows for accurate physical segment control, and thus improves the accuracy of physical segment control.

[0061] The route physical section control device provided in the present application is described below. The route physical section control device described below and the route physical section control method described above can be referenced to each other.

[0062] Figure 8 This is a schematic diagram of the structure of a physical section control device for a route provided in an embodiment of the present application. For example, see Figure 8 As shown, the route physical section control device 80 may include: The first acquisition unit 801 is configured to acquire a historical state of a first logical section in a first physical section of an approach route by a preceding vehicle and a following vehicle is applying for approaching the route based on a received cross-pressure signal from the following vehicle.

[0063] For example, in the embodiment of the present application, the control unit 803 is configured to unlock the first physical segment based on the historical state of the first logical segment and the current state of the first logical segment, including: When the historical state of the first logical segment is occupied and the current state of the first logical segment is idle, obtaining the current state of the second physical segment of the route; The first physical segment is controlled based on the current state of the second physical segment.

[0065] For example, in the embodiment of the present application, the control unit 803 is configured to control the first physical segment based on the current state of the second physical segment, including: When the current state of the second physical segment is occupied, unlocking control is performed on the first physical segment.

[0066] For example, in the embodiment of the present application, the control unit 803 is further configured to set the first physical segment to a fault locked state when the current state of the second physical segment is an idle state; In the fault-locked state, the following vehicle is controlled to enter a degraded mode.

[0067] For example, in the embodiment of the present application, the first acquiring unit 801 is configured to acquire the historical state of the first physical segment and the current state of the first physical segment based on the received cross-pressure signal of the following vehicle, including: Based on the received cross-pressure signal from the following vehicle, controlling the start signal of the route to be closed; When the starting signal is closed, the historical status of the first physical segment and the current status of the first physical segment are obtained; wherein the current status of the first physical segment is determined based on the collected axle occupancy status and the code position status of the logical segment in the first physical segment sent by the area controller.
