[0002] In order to balance the three-phase load in the power supply system as much as possible in electrified railways, the catenary generally adopts a sectional phase-changing power supply design method. Moreover, in order to prevent interphase short circuits, insulating devices are used to divide the connection points between different-phase power supply arms to form a non-powered insulating neutral section (hereinafter referred to as the "neutral section") between different-phase power supply arms, and there is a neutral section every certain distance on the line.

[0044] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] The protection method for the neutral section of a train, the computer-readable storage medium, and the protection device for the neutral section of a train according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0046] Figure 1 Flowchart of the protection method for the neutral section of a train according to an embodiment of the present invention.

[0047] Specifically, in some embodiments of the present invention, as Figure 1 shown, the protection method for the neutral section of a train includes:

[0048] S101, obtaining the starting point and the ending point of the neutral section protection, and establishing a neutral section protection area according to the starting point and the ending point of the neutral section protection.

[0049] It can be understood that in this embodiment of the present invention, the starting point and the ending point of the neutral section protection can be set accordingly according to the actual operation environment of the train, as follows:

[0050] (1) As Figure 2 shown, when the first section inside the signal machine at the start of the route where the neutral section is located is not a preset protected section, the protection point of the signal machine at the start of the route where the neutral section is located can be used as the starting point of the neutral section protection, so as to ensure that the train can stop in front of the signal machine at the start of the route, maximizing the normal operation of the train.

[0051] (2) As Figure 3 shown, when the first section inside the signal machine at the start of the route where the neutral section is located is a preset protected section (for example, a train platform), the protection point of the signal machine at the start of the route where the end point of the preset protected section is located can be used as the starting point of the neutral section protection, so as to ensure that the train can normally enter the preset protected section to achieve docking.

[0052] (3) Extending one train length forward from the end position of the neutral section as the ending point of the neutral section protection, so as to ensure that the train completely exits the neutral section. Among them, as Figure 4 andFigure 5 As shown, the protection end of the split-phase zone can be located within the axle-counting section where the split-phase zone is located, or can be located outside the axle-counting section where the split-phase zone is located.

[0053] S102. Obtain the first moving authorization end of the train, and when the first moving authorization end intrudes into the protection area of the split-phase zone, determine the start point of the protection area of the split-phase zone as the second moving authorization end.

[0054] Specifically, in this embodiment of the present invention, a corresponding description is made on the judgment of whether the first moving authorization end intrudes into the protection area of the split-phase zone:

[0055] (1) If the first moving authorization end is located before the protection start point of the split-phase zone, as Figure 6 shown, it is considered that the train will not enter the split-phase zone. At this time, it is judged that the first moving authorization end does not intrude into the protection area of the split-phase zone, and there is no need to perform a retraction process on the first moving authorization end, that is, directly determine the first moving authorization end as the second moving authorization end.

[0056] (2) If the first moving authorization end is located between the protection start point and the protection end point of the split-phase zone, as Figure 7 shown, it is considered that the train has a risk of stopping at the split-phase zone. At this time, it is judged that the first moving authorization end intrudes into the protection area of the split-phase zone, and a retraction process needs to be performed on the first moving authorization end, that is, determine the start point of the protection area of the split-phase zone as the second moving authorization end.

[0057] (3) If the first moving authorization end is located after the protection end point of the split-phase zone, as Figure 8 shown, since there is a distance corresponding to the train length reserved between the protection end point of the split-phase zone and the end point of the split-phase zone, it is considered that the rear of the train can completely drive out of the split-phase zone. At this time, it is judged that the first moving authorization end does not intrude into the protection area of the split-phase zone, and there is no need to perform a retraction process on the first moving authorization end, that is, directly determine the first moving authorization end as the second moving authorization end.

[0058] Optionally, in the above embodiment of the present invention, the first moving authorization end of the train is calculated by the line controller based on the actual operation environment of the train. Among them, the first moving authorization end is used to indicate the target stopping position of the train, and the second moving authorization end is used to indicate the final stopping position of the train when there are no other obstacles.

[0059] S103. Perform a split-phase zone protection stop operation according to the second moving authorization end.

[0060] It can be understood that in this embodiment of the present invention, a split-phase zone protection stop operation is performed according to the second moving authorization end, thereby effectively avoiding the situation that the train accidentally stops in the split-phase zone, realizing safer, more efficient and more reliable train operation management, and improving the train operation efficiency.

[0061] It should be understood that in the process of determining whether the first moving authorization end point invades the protection area of the neutral section, the influence of other obstacles on the moving authorization end point should also be considered. For example, if the first moving authorization end point of the train does not invade the protection area of the neutral section, but due to other obstacles, the subsequent moving authorization end point calculated by the line controller for the train is withdrawn to the protection area of the neutral section (that is, the subsequent moving authorization end point invades the protection area of the neutral section), the line controller still needs to perform a withdrawal process on the subsequent moving authorization end point of the train. Therefore, in some embodiments of the present invention, the following protection method for the train neutral section is also proposed:

[0062] Further, in some embodiments of the present invention, as Figure 9 shown, the method further includes:

[0063] S201, obtain the preset protection area of the train.

[0064] Optionally, in some embodiments of the present invention, the preset protection area includes at least one of the floodgate state protection area in the middle, the SPKS (Staff Protection Key Switch) protection area, the derailment protection area, the evacuation protection area, and the lane occupancy state protection area.

[0065] S202, obtain the third moving authorization end point according to the preset protection area, the protection area of the neutral section, and the first moving authorization end point.

[0066] It can be understood that in this embodiment of the present invention, the subsequent moving authorization end point is first determined according to the first moving authorization end point and the preset protection area, and then the third moving authorization end point is determined according to the subsequent moving authorization end point and the protection area of the neutral section, where the subsequent moving authorization end point is used to indicate the target parking position of the train when there are other obstacles, and the third moving authorization end point is used to indicate the final parking position of the train when there are other obstacles.

[0067] S203, perform a neutral section protection parking operation according to the third moving authorization end point.

[0068] It can be understood that in this embodiment of the present invention, a neutral section protection parking operation is performed according to the third moving authorization end point, thereby effectively avoiding the situation that the train accidentally stops in the neutral section due to avoiding other obstacles, realizing safer, more efficient, and more reliable train operation management, and improving the train operation efficiency.

[0069] Further, in some embodiments of the present invention, as Figure 10 shown, obtaining the third moving authorization end point according to the preset protection area, the protection area of the neutral section, and the first moving authorization end point includes:

[0070] S301, if the first moving authorization end point intrudes into the floodgate status protection area and the floodgate status corresponding to the floodgate status protection area is the closed state, then determine the start point of the floodgate status protection area as the fourth moving authorization end point.

[0071] Specifically, in this embodiment of the present invention, as Figure 11 shown, assume that the first moving authorization end point calculated by the line controller for the train intrudes into the floodgate status protection area and the floodgate status corresponding to the floodgate status protection area is the closed state. Then, to ensure that the train stops accurately in front of the floodgate without colliding with the floodgate, the line controller will perform a retraction process on the first moving authorization end point, that is, determine the start point of the floodgate status protection area (the start position AC1 of the axle counting section where the floodgate is located) as the fourth moving authorization end point.

[0072] S302, if the fourth moving authorization end point intrudes into the neutral section protection area, then determine the start point of the neutral section protection area as the third moving authorization end point.

[0073] It can be understood that, in this embodiment of the present invention, when the start position AC1 of the axle counting section where the floodgate is located is within the neutral section protection area and it is determined that the fourth moving authorization end point intrudes into the neutral section protection area, it is necessary to perform a retraction process on the fourth moving authorization end point again, that is, determine the start point of the neutral section protection area as the third moving authorization end point.

[0074] It should be noted that, in the above embodiment of the present invention, if the floodgate status corresponding to the floodgate status protection area is the open state, then it is determined that the train can pass through the floodgate status protection area smoothly. At this time, it is not necessary to perform a retraction process on the first moving authorization end point, that is, directly determine the first moving authorization end point as the third moving authorization end point.

[0075] Specifically, in some embodiments of the present invention, if the fourth moving authorization end point obtained after performing a retraction process on the first moving authorization end point based on the floodgate status protection area intrudes into the neutral section protection area, the line controller can also perform a retraction process on the fourth moving authorization end point again to ensure that the train does not accidentally stop within the neutral section.

[0076] Furthermore, in some embodiments of the present invention, as Figure 12 shown, obtaining the third moving authorization end point according to the preset protection area, the neutral section protection area, and the first moving authorization end point includes:

[0077] S401, if the first moving authorization end point intrudes into the SPKS protection area and the SPKS status corresponding to the SPKS protection area is the active state, then determine the start point of the SPKS protection area as the fifth moving authorization end point.

[0078] Specifically, in this embodiment of the present invention, as Figure 13 shown, assuming that the line controller calculates that the first moving authorization end point of the train intrudes into the SPKS protection area, and the SPKS status corresponding to the SPKS protection area is the active state, then, to ensure that the train stops before entering the SPKS area to avoid affecting the staff in the SPKS area, the line controller will determine the starting point of the SPKS protection area (the starting point position AC1 of the SPKS area) as the fifth moving authorization end point.

[0079] S402, if the fifth moving authorization end point intrudes into the neutral section protection area, then determine the starting point of the neutral section protection area as the third moving authorization end point.

[0080] It can be understood that in this embodiment of the present invention, when the starting point position AC1 of the SPKS area is within the neutral section protection area, it is determined that the fifth moving authorization end point intrudes into the neutral section protection area, and it is necessary to perform a retraction process on the fifth moving authorization end point again, that is, determine the starting point of the neutral section protection area as the third moving authorization end point.

[0081] It should be noted that in the above embodiment of the present invention, if the SPKS status corresponding to the SPKS protection area is the non-active state, it is determined that the train can pass through the SPKS protection area smoothly. At this time, it is not necessary to perform a retraction process on the first moving authorization end point, that is, directly determine the first moving authorization end point as the third moving authorization end point.

[0082] Specifically, in some embodiments of the present invention, if the fifth moving authorization end point obtained after performing a retraction process on the first moving authorization end point based on the SPKS protection area intrudes into the neutral section protection area, the line controller can also perform a retraction process on the fifth moving authorization end point again to ensure that the train does not accidentally stop in the neutral section.

[0083] Further, in some embodiments of the present invention, as Figure 14 shown, obtaining the third moving authorization end point according to the preset protection area, the neutral section protection area, and the first moving authorization end point includes:

[0084] S501, if the first moving authorization end point intrudes into the derailment protection area or is located after the end point of the derailment protection area, then determine the starting point of the derailment protection area as the sixth moving authorization end point.

[0085] Specifically, in this embodiment of the present invention, as Figure 15As shown, assuming that the first movement authorization end point calculated by the line controller for the train intrudes into the derailment protection area or is located after the end point of the derailment protection area, then, to ensure that the train does not enter the derailment protection area and collide with other trains, the line controller will determine the starting point of the derailment protection area (the starting point position AC1 of the derailment protection area) as the sixth movement authorization end point.

[0086] S502, if the sixth movement authorization end point intrudes into the neutral section protection area, then determine the starting point of the neutral section protection area as the third movement authorization end point.

[0087] It can be understood that in this embodiment of the present invention, when the starting point position AC1 of the derailment protection area is within the neutral section protection area, to determine that the sixth movement authorization end point intrudes into the neutral section protection area, it is necessary to perform a retraction process on the sixth movement authorization end point again, that is, determine the starting point of the neutral section protection area as the third movement authorization end point.

[0088] It should be noted that in the above embodiment of the present invention, if the first movement authorization end point is located before the starting point of the derailment protection area, at this time, it is not necessary to perform a retraction process on the first movement authorization end point, that is, directly determine the first movement authorization end point as the third movement authorization end point.

[0089] Specifically, in some embodiments of the present invention, if the sixth movement authorization end point obtained after performing a retraction process on the first movement authorization end point based on the derailment protection area intrudes into the neutral section protection area, the line controller can also perform a retraction process on the sixth movement authorization end point again to ensure that the train does not accidentally stop within the neutral section.

[0090] Furthermore, in some embodiments of the present invention, as Figure 16 shown, obtaining the third movement authorization end point according to the preset protection area, the neutral section protection area, and the first movement authorization end point includes:

[0091] S601, if the first movement authorization end point intrudes into the evacuation protection area or is located after the end point of the evacuation protection area, then determine the starting point of the evacuation protection area as the seventh movement authorization end point.

[0092] Specifically, in this embodiment of the present invention, as Figure 17 shown, assuming that the first movement authorization end point calculated by the line controller for the train intrudes into the evacuation protection area or is located after the end point of the evacuation protection area, then, to ensure that the train does not enter the evacuation protection area and affect the evacuation of passengers, the line controller will determine the starting point of the evacuation protection area (the starting point position AC1 of the evacuation protection area) as the seventh movement authorization end point.

[0093] S602, if the seventh moving authorization end point intrudes into the protection area of the neutral section, the starting point of the protection area of the neutral section is determined as the third moving authorization end point.

[0094] It can be understood that in this embodiment of the present invention, when the starting position AC1 of the evacuation protection area is within the protection area of the neutral section, it is determined that the seventh moving authorization end point intrudes into the protection area of the neutral section, and the seventh moving authorization end point needs to be retracted again, that is, the starting point of the protection area of the neutral section is determined as the third moving authorization end point.

[0095] It should be noted that in the above embodiment of the present invention, if the first moving authorization end point is located in front of the starting point of the evacuation protection area, at this time, it is not necessary to retract the first moving authorization end point, that is, the first moving authorization end point is directly determined as the third moving authorization end point.

[0096] Specifically, in some embodiments of the present invention, if the seventh moving authorization end point obtained after retracting the first moving authorization end point based on the evacuation protection area intrudes into the protection area of the neutral section, the line controller can also retract the seventh moving authorization end point again to ensure that the train will not accidentally stop in the neutral section.

[0097] Further, in some embodiments of the present invention, as Figure 18 shown, obtaining the third moving authorization end point according to the preset protection area, the protection area of the neutral section and the first moving authorization end point includes:

[0098] S701, if the first moving authorization end point intrudes into the protection area of the lane occupancy state, and the lane occupancy state corresponding to the protection area of the lane occupancy state is the occupied state, the eighth moving authorization end point is determined according to the occupied state.

[0099] Specifically, in this embodiment of the present invention, assuming that the first moving authorization end point calculated by the line controller for the train intrudes into the protection area of the lane occupancy state, and the lane occupancy state corresponding to the protection area of the lane occupancy state is the occupied state, then, to ensure that the train will not enter the protection area of the lane occupancy state and collide with other vehicles, the line controller will determine the eighth moving authorization end point according to the occupied state, as follows:

[0100] (1) If the occupied state is that there is another train within the range of the first moving authorization end point, then, as Figure 19 shown, it is necessary to retract the first moving authorization end point of the train to a safe position (located between AC1 and the preceding train) extending backward from the rear of the preceding train, and use this safe position as the eighth authorized moving end point to prevent the preceding train from retreating or rolling back.

[0101] (2) If the occupied state is that there is a non - communication vehicle occupying an axle counter section within the first moving authorization end range, then, as Figure 20 shown, it is necessary to withdraw the first moving authorization end of the train backward by one axle counter section from the AC2 position to the safe position of AC1, and use this safe position as the eighth authorized moving end point to prevent the train from colliding with the non - communication vehicle.

[0102] (3) If the occupied state is that there is a redundant non - communication vehicle occupying an axle counter section within the first moving authorization end range, then, as Figure 21 shown, it is necessary to withdraw the first moving authorization end of the train by a safety protection distance to the safe position of AC1, and use this safe position as the eighth authorized moving end point.

[0103] S702, if the eighth moving authorization end point intrudes into the neutral section protection area, then determine the starting point of the neutral section protection area as the third moving authorization end point.

[0104] It can be understood that in this embodiment of the present invention, when the aforementioned safe position is within the neutral section protection area, it is determined that the eighth moving authorization end point intrudes into the neutral section protection area, and it is necessary to perform a withdrawal process on the eighth moving authorization end point again, that is, determine the starting point of the neutral section protection area as the third moving authorization end point.

[0105] It should be noted that in the above - mentioned embodiment of the present invention, if the lane occupancy state corresponding to the lane occupancy state protection area is an unoccupied state, or the aforementioned safe position is not within the neutral section protection area, at this time, there is no need to perform a withdrawal process on the first moving authorization end point, that is, directly determine the first moving authorization end point as the third moving authorization end point.

[0106] Specifically, in some embodiments of the present invention, if the eighth moving authorization end point obtained after performing a withdrawal process on the first moving authorization end point based on the lane occupancy state protection area intrudes into the neutral section protection area, the line controller can also perform a withdrawal process on the eighth moving authorization end point again to ensure that the train will not accidentally stop within the neutral section.

[0107] In summary, according to the protection method for the neutral section of a train in an embodiment of the present invention, the starting point and the ending point of the neutral section protection are obtained, and a neutral section protection area is established based on the starting point and the ending point of the neutral section protection. Furthermore, the first moving authorization ending point of the train is obtained, and when the first moving authorization ending point invades the neutral section protection area, the starting point of the neutral section protection area is determined as the second moving authorization ending point, and, according to the second moving authorization ending point, a neutral section protection stop operation is performed. Thus, by establishing a neutral section protection area in advance and combining it with the moving authorization ending point of the train, the neutral section protection stop operation is accurately performed, thereby effectively avoiding the situation where the train accidentally stops in the neutral section, realizing safer, more efficient, and more reliable train operation management, and improving the train operation efficiency.

[0108] Based on the foregoing protection method for the neutral section of a train in an embodiment of the present invention, an embodiment of the present invention also proposes a computer-readable storage medium, on which a protection program for the neutral section of a train is stored. When the protection program for the neutral section of a train is executed by a processor, the protection method for the neutral section of a train in the foregoing embodiment of the present invention is implemented.
