[0001] The present invention relates to the technical field of railway marshaling yards, and in particular to a control method, device, equipment and storage medium for a railway crossing. Background Art

[0002] A crossing is the intersection of a railway track and a road. Usually, alarm facilities, railings, and personnel guarding are used to ensure the safety of pedestrians and motor vehicles when a train passes through the crossing. In some industrial and mining enterprises, the railways and roads are intricately intertwined, with many crossings. At the same time, railway shunting operations are complex and frequent, which often cause crossing alarms and reduce the transportation capacity of the road.

[0003] When a train is turning back, sometimes the train stops near a crossing and triggers the crossing alarm device without actually passing through the crossing and turning back. In this case, the train does not actually occupy the crossing, but triggers the crossing alarm, affecting the passage of pedestrians and motor vehicles and reducing the transportation capacity of the road. Therefore, how to reduce unnecessary crossing occupation during shunting operations is very important for improving the transportation efficiency on the road side of the railway shunting yard. Summary of the invention

[0032] Embodiment 1

[0033] Figure 1 A flow chart of a method for controlling a railway crossing is provided for the first embodiment of the present invention. This embodiment is applicable to the case where a train performs a turnaround operation in a section including a crossing. The method can be executed by a control device for a railway crossing. The control device for a railway crossing can be implemented in the form of hardware and / or software. The control device for a railway crossing can be configured in various general-purpose computing devices. Figure 1 As shown, the method includes:

[0034] S110, obtaining a shunting route instruction set; the shunting route instruction set includes multiple route instructions, and the route instruction comprises a single route composed of a source section and a destination section; the shunting route instruction set includes a section where a crossing is located.

[0035] The shunting route instruction set is sent by the route instruction generation program, and contains instructions for multiple routes arranged in sequence. It is used to issue route control commands to the interlocking system to arrange the corresponding routes. The shunting route instruction set contains multiple route instructions arranged in sequence. Each route includes a source section, a destination section, a source port, and a destination port. Each route instruction consists of a single route composed of a source section and a destination section. The direction in which the train leaves the source section is the source port, and the direction in which the train enters the destination section is the destination port.

[0036] In a railway shunting yard, the railways and roads are complex and there are many crossings. When a train turns back, sometimes the train stops near a crossing and triggers the crossing alarm device without actually passing through the crossing. In order to reduce unnecessary crossing occupation and improve the transportation efficiency on the road side, the embodiment of the present invention focuses on the crossing control method when the shunting route instruction set includes the section where the crossing is located.

[0037] In a specific example, the shunting route instruction set includes 4 route instructions, namely route instruction 1: G3 to T2; route instruction 2: T2 to T1; route instruction 3: T1 to T2; route instruction 4: T2 to G2. Among them, G3, T2, T1 and T2 are sections in the railway, and T1 is the section where the crossing is located. Taking route instruction 1 as an example, it is used to guide the train from section G3 to section T2, that is, in route instruction 1, G3 is the source section, T2 is the destination section, and the single route of the train is composed of section G3 to section T2.

[0038] S120. Determine the return route according to the source section and the destination section associated with the route instructions in the shunting route instruction set.

[0039] The technical goal to be achieved in the embodiments of the present invention is to reduce unnecessary occupation of the crossing when the train turns back. For example, the train stops at the crossing and turns back without entering the crossing, that is, the train will not occupy the crossing, but the crossing equipment alarm will be triggered when the train approaches the crossing, thereby causing unnecessary occupation of the crossing. Therefore, in the embodiments of the present invention, after obtaining the shunting route instruction set, it is necessary to determine the turning route included in the shunting route instruction set according to the source section and destination section associated with the route instruction in the shunting route instruction set.

[0040] Specifically, the route instructions in the shunting route instruction set can be traversed. For the i-th route instruction in the shunting route instruction set, if the train enters the destination section from one side (south / north), and the i+1-th route instruction leaves this section from the same side, then it is determined that the route arranged by the i-th route instruction and the i+1-th route instruction constitutes a reversing route.

[0041] S130. Determine whether the train will occupy the section where the crossing is located based on the shunting route instruction set, the train length, and the return route.

[0042] In the embodiment of the present invention, when it is determined that the shunting route instruction set includes a reversing route, it can be first determined whether the reversing route includes the section where the crossing is located. If the reversing route includes the section where the crossing is located, it indicates that the train may turn around at the crossing without passing through the crossing, but the crossing alarm is triggered, causing unnecessary occupation of the crossing. At this time, it can be further determined whether the train will occupy the section where the crossing is located based on the shunting route instruction set, the train length, and the reversing route; if the reversing route does not include the section where the crossing is located, it indicates that the train will not turn around at the crossing, that is, the train will pass through and occupy the crossing, and no subsequent operations need to be performed.

[0043] Among them, according to the shunting route instruction set, the length of the train and the reversing route, the specific method of determining whether the train will occupy the section where the crossing is located can be: according to the shunting route instruction set and the reversing route, determine the train forward path (before reversing) and the train return path (after reversing) that the train travels under the guidance of the shunting route instruction set. Then, according to the train forward path and the train return path, determine the nearest reversing point of the train, that is, the earliest switch where the train can reversal without considering the length of the train. Finally, determine whether the distance from the crossing to the nearest reversing point can accommodate the length of the train, that is, whether the distance from the crossing to the nearest reversing point can be greater than the length of the train. If so, it is determined that the train will not occupy the section where the crossing is located. Otherwise, it is determined that the train will occupy the section where the crossing is located.

[0044] In addition to the above-mentioned situation where a reversing route is searched in the shunting route instruction set, if the shunting route instruction set does not include a reversing route, the train will not turn around at the crossing, that is, the train will pass through and occupy the crossing, and no subsequent operations are required.

[0045] S140. When the train does not occupy the section where the crossing is located, a notification to disable the alarm device is sent to the crossing equipment in the section where the crossing is located.

[0046] In the embodiment of the present invention, when it is determined that the train does not occupy the section where the crossing is located, a notification of disabling the alarm device is sent to the crossing equipment in the section where the crossing is located. At this time, the crossing equipment will not alarm due to the train approaching the crossing, and unnecessary occupation of the crossing will not be caused.

[0047] The technical solution of the embodiment of the present invention searches for the turning route that the train needs to travel in the shunting route instruction set, and determines whether the train will occupy the section where the crossing is located based on the shunting route instruction set, the train length and the turning route. When the train does not occupy the section where the crossing is located, a notification to disable the alarm device is sent to the crossing equipment in the section where the crossing is located. This can avoid the triggering of the alarm device when the train turns back at the crossing and does not occupy the crossing, thereby improving the transportation efficiency on the highway side.

[0048] Embodiment 2

[0049] Figure 2a This is a flow chart of a railway crossing control method provided in the second embodiment of the present invention. This embodiment further refines the above embodiment and provides specific steps for determining the return route according to the source section and destination section associated with the route instruction in the shunting route instruction set, and specific steps for determining whether the train will occupy the section where the crossing is located according to the shunting route instruction set, the train length and the return route. Figure 2a As shown, the method includes:

[0050] S210, obtaining a shunting route instruction set; the shunting route instruction set includes multiple route instructions, and the route instruction comprises a single route composed of a source section and a destination section; the shunting route instruction set includes the section where the crossing is located.

[0051] The specific railway crossing control process in the embodiment of the present invention is as follows Figure 2b As shown, after obtaining the shunting route instruction set, the instruction status can be checked. If the instruction status is successful, it means that the sorting instruction has been issued to the interlocking, the track section in the route has become locked and the signal state corresponding to the route is an open permission signal, and the subsequent steps of the embodiment of the present invention can be executed. If the instruction status is ended, it means that the route is cleared with a red light belt and the track section is unlocked, that is, the train has passed through this route, and the subsequent operations of the embodiment of the present invention are not executed.

[0052] S220. Extract two adjacent route instructions from the shunting route instruction set in turn as the current instruction pair; in the current instruction pair, the destination segment of the preceding route instruction and the source segment of the succeeding route instruction are the same.

[0053] In the embodiment of the present invention, in order to determine the return route in the shunting route instruction set, two adjacent route instructions are sequentially extracted from the shunting route instruction set as the current instruction pair to locate and guide the two adjacent route instructions of the return route. Among them, in the current instruction pair, the destination section of the preceding route instruction and the source section of the succeeding route instruction are the same. Among them, the preceding route instruction and the succeeding route instruction are determined based on the arrangement order of the route instructions in the shunting route instruction set.

[0054] In a specific example, the shunting route instruction set includes route instruction 1, route instruction 2, route instruction 3 and route instruction 4, then route instruction 1 and route instruction 2, route instruction 2 and route instruction 3, ... are sequentially extracted as the current instruction pair until the return route is found or the traversal of all route instructions in the shunting route instruction set is completed. Taking the current instruction pair consisting of route instruction 2 and route instruction 3 as an example, route instruction 2 is the preceding route instruction, and route instruction 3 is the succeeding route instruction.

[0055] S230, determining whether the direction in which the preceding route instruction in the current instruction pair enters the target segment is the same as the direction in which the succeeding route instruction leaves the source segment.

[0056] In the embodiment of the present invention, after extracting the current instruction pair, it is determined whether the direction of the current route instruction entering the target segment is the same as the direction of the subsequent route instruction leaving the source segment. Since in the current instruction pair, the target segment of the preceding route instruction and the source segment of the subsequent route instruction are the same. The above determination can also be understood as determining whether the direction of entering the target segment (segment A) in the i-th route instruction and the direction of leaving the source segment (segment A) in the i+1-th route instruction are the same.

[0057] S240. When the direction in which the preceding route instruction enters the target segment is the same as the direction in which the succeeding route instruction leaves the source segment, determine that the arranged routes of the current instruction constitute a reentry route.

[0058] In an embodiment of the present invention, when the direction in which the preceding route instruction enters the target segment is the same as the direction in which the succeeding route instruction leaves the source segment, it is determined that the arranged routes of the current instruction constitute a reentry route, and the segment equipment associated with the reentry route is added to the segment equipment list.

[0059] In a specific example, Figure 2c As shown in the figure, when the train performs shunting operations from G3 to G2, it needs to turn back in the direction of the T1 section where the crossing is located. Specifically, the shunting route instruction set includes 4 route instructions, namely route instruction 1: G3 to T2; route instruction 2: T2 to T1; route instruction 3: T1 to T2; route instruction 4: T2 to G2. Among them, G3, T2, T1 and T2 are sections in the railway, and T1 is the section where the crossing is located. The circular annotations represent the signal machines of the source port and destination port of each section.

[0060] Route instruction 2 enters the target section from the north side of the target section (T1 section), and route instruction 3 leaves the source section from the north side of the source section (T1 section), then it is determined that the route arranged by the current instruction pair (route instruction 2 and route instruction 3) constitutes a return route. At this time, T2, turnout 1 (positioning) and T1 can be added to the section equipment list.

[0061] S250. Determine the continuation routes of the forward route and the return route in the turnaround route in the shunting route instruction set.

[0062] The continuation route is the opposite of the return route. The route in which the train does not turn back in a certain section but continues to move in the current direction to the next section is called the continuation route.

[0063] In the embodiment of the present invention, in order to determine the entire path of the train, it is necessary to further determine the continuation routes of the forward route and the return route in the return route in the shunting route instruction set. Among them, the route corresponding to the preceding route instruction is called the forward route in the return route, and the route corresponding to the subsequent route instruction is called the return route in the return route, and the section equipment associated with the continuation route is added to the section equipment list.

[0064] Specifically, the i-th route instruction and the i+1-th route instruction constitute the return route. Starting from the i-th route instruction, search for its predecessor route instruction in reverse order in the shunting route instruction set, and determine in turn whether the routes arranged by the two adjacent route instructions constitute a continuous route.

[0065] Taking the i+1th route instruction as the starting point, search for its subsequent route instruction in the shunting route instruction set in positive order, and determine in turn whether the routes arranged by the two adjacent route instructions constitute a continuous route.

[0066] The method for determining whether the routes arranged by two route instructions constitute a continuous route is that for the i-th instruction, it enters the destination section from one side. If the i+1-th instruction leaves this section from the opposite side, then the routes arranged by the two route instructions constitute a continuous route.

[0067] Optionally, the continuation routes of the forward route and the return route in the turnaround route are determined in the shunting route instruction set, including:

[0068] Taking the preceding route instruction associated with the forward route in the return route as the starting point, search the route instruction in reverse order in the shunting route instruction set to determine the continuation route of the forward route;

[0069] Taking the subsequent route instruction associated with the return route in the reversing route as the starting point, search for the route instruction in the positive sequence in the shunting route instruction set to determine the continuation route of the return route.

[0070] In this optional embodiment, a specific method for determining the continuation routes of the forward route and the return route in the turnaround route in the shunting route instruction set is provided: starting from the preceding route instruction associated with the forward route in the turnaround route, the route instruction is searched in reverse order in the shunting route instruction set to determine the continuation route of the forward route. Starting from the succeeding route instruction associated with the return route in the turnaround route, the route instruction is searched in forward order in the shunting route instruction set to determine the continuation route of the return route.

[0071] Still Figure 2c For example, starting from the previous route instruction 2 associated with the forward route, search for route instruction 1 in reverse order in the shunting route instruction set to determine the continued route associated with the forward route. Starting from the previous route instruction 3 associated with the return route, search for route instruction 4 in the shunting route instruction set to determine the continued route associated with the return route.

[0072] Optionally, starting from the previous route instruction associated with the forward route in the return route, the route instruction is searched in reverse order in the shunting route instruction set to determine the continuation route of the forward route, including:

[0073] Taking the preceding route instruction associated with the forward route in the return route as the starting point, two adjacent route instructions are sequentially extracted from the shunting route instruction set in reverse order as the current instruction pair; in the current instruction pair, the destination section of the preceding route instruction and the source section of the succeeding route instruction are the same;

[0074] Determine whether the direction in which the preceding route instruction in the current instruction pair enters the target section is opposite to the direction in which the succeeding route instruction leaves the source section;

[0075] When the direction in which the preceding route instruction enters the target segment is opposite to the direction in which the succeeding route instruction leaves the source segment, it is determined that the current instruction constitutes a continuation of the forward route for the arranged routes.

[0076] In this optional embodiment, a specific method is provided for determining the continuation of the forward route by using the preceding route instruction associated with the forward route in the return route as the starting point, searching for route instructions in reverse order in the shunting route instruction set, and determining the continuation of the forward route: first, using the preceding route instruction associated with the forward route in the return route as the starting point, successively extracting two adjacent route instructions in reverse order from the shunting route instruction set as the current instruction pair; in the current instruction pair, the destination segment of the preceding route instruction and the source segment of the subsequent route instruction are the same. Further, determine whether the direction in which the preceding route instruction in the current instruction pair enters the target segment and the direction in which the subsequent route instruction leaves the source segment are opposite. In the case that the direction in which the preceding route instruction enters the target segment and the direction in which the subsequent route instruction leaves the source segment are opposite, determine that the route arranged by the current instruction pair constitutes the continuation of the forward route.

[0077] Optionally, starting from the subsequent route instruction associated with the return route in the turnaround route, the route instruction is searched in the forward sequence in the shunting route instruction set to determine the continuation route of the return route, including:

[0078] Taking the subsequent route instruction associated with the return route in the reversing route as the starting point, two adjacent route instructions are sequentially extracted from the shunting route instruction set as the current instruction pair; in the current instruction pair, the destination section of the preceding route instruction is the same as the source section of the subsequent route instruction;

[0079] Determine whether the direction in which the preceding route instruction in the current instruction pair enters the target section is opposite to the direction in which the succeeding route instruction leaves the source section;

[0080] When the direction in which the preceding route instruction enters the target segment is opposite to the direction in which the succeeding route instruction leaves the source segment, it is determined that the current instruction constitutes a continuation of the return route for the arranged routes.

[0081] Still Figure 2cFor example, route instruction 1: G3 to T2; route instruction 2: T2 to T1; route instruction 3: T1 to T2; route instruction 4: T2 to G2. Among them, route instruction 2 and route instruction 3 constitute a return route. For route instruction 2, find its predecessor instruction. Since route instruction 1 enters T2 from the north side of the destination section T2, and route instruction 2 leaves T2 from the south side of the source section T2, the directions are opposite, so the route arranged by route instruction 2 constitutes the continuation of the route arranged by route instruction 1. Similarly, since route instruction 3 enters T2 from the south side of the destination section T2, and route instruction 4 leaves T2 from the north side of the source section T2, the directions are opposite, so the route arranged by route instruction 4 constitutes the continuation of the route arranged by route instruction 3. At this time, G3, turnout No. 3 and G2 can be added to the section equipment list.

[0082] S260. The forward route in the reversing route and the continued route associated with the forward route constitute the train's forward path, and the return route in the reversing route and the continued route associated with the return route constitute the train's return path.

[0083] In the embodiment of the present invention, after determining the reversing route included in the shunting route instruction set and the continued route associated with the reversing route, the forward route in the reversing route and the continued route associated with the forward route constitute the train forward path, and obtain the equipment chain on the train forward path. The return route in the reversing route and the continued route associated with the return route constitute the train return path, and obtain the equipment chain on the train return path.

[0084] S270. Determine the nearest turning point of the train based on the section equipment on the train's forward path and the train's return path.

[0085] In the embodiment of the present invention, the nearest turning point of the train is determined according to the section equipment on the train forward path and the train return path. Specifically, the section equipment on the train forward path and the train return path are compared, and the first turnout with a different direction found along the return path starting from the section passing through the crossing is the nearest turning point.

[0086] Optionally, the nearest turning point of the train is determined based on the section equipment on the train forward path and the train return path, including:

[0087] In the section equipment on the train forward path and the train return path associated with the shunting route instruction set, the turnout direction is determined respectively;

[0088] Among the same turnouts included in the train's forward path and return path, the first turnout that opens in different directions in the train's forward path and the train's return path is determined as the train's nearest turning point.

[0089] In this optional embodiment, a specific method is provided for determining the nearest turning point of the train based on the section equipment on the train's forward path and the train's return path: in the section equipment on the train's forward path and the train's return path associated with the shunting route instruction set, the direction of the turnout is determined respectively, and among the same turnouts included in the train's forward path and the train's return path, the first turnout that opens in different directions in the train's forward path and the train's return path is determined as the train's nearest turning point.

[0090] Still Figure 2c For example, route instruction 1: G3 to T2; route instruction 2: T2 to T1; route instruction 3: T1 to T2; route instruction 4: T2 to G2. Among them, route instruction 2 and route instruction 3 constitute a reversing route. The route arranged by route instruction 2 constitutes a continuation of the route arranged by route instruction 1, and the equipment chain on the train's forward path can be obtained: turnout No. 3 (reverse position), T2, turnout No. 1 (positioning) and T1. The route arranged by route instruction 4 constitutes a continuation of the route arranged by route instruction 3, and the equipment chain on the train's return path can be obtained: T1, turnout No. 1 (positioning), T2, turnout No. 3 (positioning). It can be seen that among the same turnouts included in the train's forward path and return path, the first turnout that opens to different directions in the train's forward path and the train's return path is turnout No. 3, which means that turnout No. 3 can be determined as the train's nearest turning point.

[0091] S280, calculating the cumulative length of the section from the section where the crossing is located to the nearest turning point, and when the train length is less than the cumulative length, determining that the train does not occupy the section where the crossing is located.

[0092] In the embodiment of the present invention, the cumulative length of the section from the section where the crossing is located to the nearest turning point is calculated, and when the length of the train is less than the cumulative length, it is determined that the train does not occupy the section where the crossing is located. Specifically, the section length is read according to the static data configuration, and the total length of the section from the crossing to the nearest turning point is calculated. If the total length is greater than the length of the train, the train does not need to occupy the crossing during operation, otherwise it needs to occupy the crossing.

[0093] In a specific example, as shown in Figure 2, route instruction 1: G3 to T2; route instruction 2: T2 to T1; route instruction 3: T1 to T2; route instruction 4: T2 to G2. Among them, route instruction 2 and route instruction 3 constitute a reversing route. The route arranged by route instruction 2 constitutes a continuation of the route arranged by route instruction 1, and the route arranged by route instruction 4 constitutes a continuation of the route arranged by route instruction 3. Turnout No. 3 is the nearest turning point for the train. Calculate the cumulative length of the section from the section where the crossing is located to the nearest turning point, that is, calculate the cumulative length of the section where turnout No. 1 is located and the T2 section. When the train length is less than the cumulative length, it is determined that the train does not occupy the section where the crossing is located.

[0094] S290. When the train does not occupy the section where the crossing is located, a notification to disable the alarm device is sent to the crossing equipment in the section where the crossing is located.

[0095] S291. After the return route on the train return path is cleared, a notification to activate the alarm device is sent to the crossing equipment in the section where the crossing is located.

[0096] In the embodiment of the present invention, after the return route on the train return path is cleared, a notification to activate the alarm device is sent to the crossing equipment in the section where the crossing is located. Still taking Figure 2 as an example, when it is detected that the route of route instruction 3 (T1 to T2) has been cleared, it means that the train has left the T2 section and started to enter G2, then a notification is sent to the crossing equipment to activate the alarm device.

[0097] The technical solution of the embodiment of the present invention searches for the return route that the train needs to travel in the shunting route instruction set, and then determines the continuation routes of the forward route and the return route in the return route in the shunting route instruction set respectively, the forward route in the return route and the continuation route associated with the forward route constitute the forward path of the train, and the return route in the return route and the continuation route associated with the return route constitute the return path of the train, and according to the section equipment on the forward path of the train and the return path of the train, the nearest turning point of the train is determined, and the cumulative length of the section from the section where the crossing is located to the nearest turning point is calculated. When the train length is less than the cumulative length, it is determined that the train does not occupy the section where the crossing is located, and the train can turn back at the crossing. When the crossing is not occupied, the triggering of the alarm device is avoided, thereby improving the transportation efficiency on the highway side.
