Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to overcome the above problems in the prior art, embodiments of the present invention provide a method and an apparatus for detecting a route selection conflict, where before a current train enters a route to be arranged, a path conflict is detected on the route to be arranged of the current train, and it is determined whether a path conflict exists on the route to be arranged of the current train, so that it is possible to avoid that the route selected by the current train and other trains impose the same section, avoid a jam in a track section, and improve train operation efficiency.
Fig. 1 is a schematic flowchart of a method for detecting a routing conflict according to an embodiment of the present invention. The following describes a method for detecting a routing conflict according to an embodiment of the present invention with reference to fig. 1. As shown in fig. 1, the method includes: and S101, acquiring a route to be arranged of the current train and the selected route or planned driving route of other trains.
Specifically, a train route refers to a route on which a train, a head yard train or a train runs from one location to another. The range of the route comprises stations, turnouts, track sections and the like.
According to the configuration situation of the station yard line, multiple possible operation schemes exist between two points on the line, namely multiple routes are available between the starting end and the terminal end of the route. In the actual operation of a train, a route which has little influence on other operations needs to be selected and arranged as a route to be arranged of the train, and other routes are used as alternative routes (or called detour routes) of the train.
The current route to be arranged of the train can be obtained through an ATS system, a train planned operation diagram or by combining the state of signal equipment and a train route terminal. The current route to be arranged by the train can comprise information of passing stations, switches and track sections.
Furthermore, the route selected by other trains or the planned driving route can be acquired through an ATS system, a train planned operation diagram and the like.
It should be noted that the ATS system can implement supervision and control of train operation, and includes functions of centralized monitoring of train operation, route selection, generating a train schedule, recording train operation track, recording train operation data and generating a report, and automatically monitoring the operation state of the device. Based on the function of the ATS system, information such as a route to be arranged of a train, a route selected by the train, a planned travel route of the train, equipment information included in a certain route, the current state of a certain equipment, the time when the train arrives at the equipment, or the physical position of the current time of the train can be acquired through the ATS system.
And S102, if judging that the route to be arranged of the current train has a route conflict with the routes already selected by other trains or the planned driving route, detecting that the route selection conflict can be generated on the route to be arranged of the current train.
Specifically, before the current train enters the to-be-scheduled route, whether the to-be-scheduled route of the current train generates a route selection conflict or not is detected, so that the situation that the current train and other trains impose the same section to cause a path conflict can be avoided.
If the route to be scheduled of the current train and the selected route or the planned driving route of other trains comprise the same section or equipment, and the current train and other trains are in the section at the same time or train technical operation is arranged aiming at the equipment, the situation that the route to be scheduled of the current train and the selected route or the planned driving route of other trains have route conflict can be judged and known.
Specifically, the route path conflict may include, but is not limited to, the following:
1. the train route and the train route which are opposite on the same arrival and departure line;
2. the train route and the shunting route which are opposite on the same arrival and departure line;
3. the same throat area is opposite to the overlapped train route;
4. the same throat area is opposite to the overlapped or forward overlapped train access and shunting access;
5. the same throat area is opposite to the overlapped shunting approach.
The throat area is a place where turnouts at two ends of a station (or a train yard) converge, and is a necessary place for various operations (such as arrival and departure of trains, running of locomotives, shunting, vehicle taking and delivering operations and the like).
The train technical work may include departure work, arrival work, delivery work, pickup work, staging work, marshalling work, and the like.
If the route to be arranged of the current train conflicts with the route already selected by other trains or the route planned to run, the route selection conflict generated by the route to be arranged of the current train can be detected.
After detecting that the route selection conflict can be generated on the route to be arranged of the current train, the operations of giving up the route to be arranged, stopping for waiting or reselecting the route and the like can be carried out on the current train according to the actual situation.
It should be noted that, if the current train gives up the route to be scheduled and reselects the scheduled route in the alternative route, the route scheduling conflict detection is performed on the newly scheduled route of the current train.
The embodiment of the invention detects the path conflict of the route to be arranged of the current train according to the route to be arranged of the current train and the selected route or the planned driving path of other trains, judges whether the route to be arranged of the current train has the path conflict with the route selected by other trains or the planned driving path of other trains or not through the detection of the path conflict, can detect that the route to be arranged of the current train generates the route selection conflict before the current train drives into the route to be arranged, can avoid the same section being imposed on the route selected by the current train and other trains, can avoid the blockage in the track section, can improve the running efficiency of the train, can adapt to more actual running scenes of the train, and can overcome the route selection limit caused by special station types.
Based on the content of the above embodiments, for an outbound route or a folded route, if it is determined that the scheduling timing of the route to be scheduled of the current train satisfies the preset condition, it is detected that a route scheduling conflict may occur on the route to be scheduled of the current train.
The outbound route refers to a route from a station to a section.
The folding-out route is divided into a folding-back route and a signing-out route, belongs to a shunting route and is usually completed in a station.
When a train runs in a warehouse-out route or a folding-out route, a preset technical operation needs to be finished within a certain time.
The preset technical jobs may include: the train leaves the warehouse from the station or the train turns back and signs out before the station according to the operation plan.
And for the outbound route or the folded outbound route, the selection and arrangement time of the route to be arranged of the current train is controllable. By controlling the selection and arrangement time of the route to be arranged of the current train, the situation that the current train and other trains acquire the same section and cause path conflict can be avoided.
Specifically, whether the route selection conflict is generated on the route to be selected of the current train can be detected by judging whether the selection and arrangement time of the route to be selected of the current train meets the preset condition.
Specifically, the timing of selecting the route to be arranged of the current train does not meet the preset condition, and can be divided into two cases: the selection and arrangement time of the route to be arranged of the current train is advanced or delayed.
If the current train is selected in advance, the current train can drive into the route to be arranged in advance. At this time, other trains have not completed technical work in the route to be arranged of the current train, and the current train enters the route to be arranged and then has a path conflict with the train in the route to be arranged.
If the current train is delayed in the arrangement opportunity, the current train can delay to enter the route to be arranged, the current train can delay to exit the route to be arranged, and other trains enter the route to be arranged according to the original plan at the moment and conflict with the current train in the route to be arranged of the current train.
It should be noted that, for the outbound route and the folded outbound route, a certain time needs to be reserved, so that the current train can complete the preset technical operation in the route to be arranged in the time period, and drive out the route to be arranged. The reserved time period takes the time of the route selection of the current train to be arranged as a starting point. If the current train finishes the preset technical operation in the reserved time period and drives out of the route to be arranged, other trains enter the route to be arranged of the current train without generating path conflict with the current train. If the current train drives into the route to be arranged in a delayed manner, the remaining time is not enough for the current train to complete the preset technical operation in the preset time period, the current train drives out of the route to be arranged in a delayed manner, and other trains drive into the route to be arranged according to the original plan at the moment and conflict with the current train in the route to be arranged of the current train.
The embodiment of the invention aims at the outbound route or the folded route, detects whether the route selection conflict is generated on the route to be arranged of the current train in the outbound route or the folded route by judging whether the selection and arrangement time of the route to be arranged of the current train meets the preset condition, can detect that the route selection conflict is generated on the route to be arranged of the current train in the outbound route or the folded route, can avoid the current train from driving into the route to be arranged in advance or in delay, can avoid the current train from blocking the outbound route or the folded route, and can improve the running efficiency of the train.
Based on the content of the above embodiments, the specific step of judging whether the route to be scheduled of the current train conflicts with the routes selected by other trains or the planned driving route, and whether the route conflicts exist, includes: and if the current train is a head-mounted train, judging whether the route to be arranged of the current train and the selected routes of other trains have common sections or turnout equipment.
The head car is an unintended car to which a destination is assigned. In actual operation, because the time of reaching the equipment such as a turnout or a platform cannot be determined, when the head yard train selects a route, the route to be selected can easily use the equipment such as the same section or the turnout with other trains, so that a path conflict occurs, other trains are blocked from passing through the conflict section, and the train operation efficiency is reduced.
Aiming at the problems, before the head-mounted vehicle drives into the route to be arranged, whether the route to be arranged of the head-mounted vehicle generates route selection conflict or not is detected, and the problem that the head-mounted vehicle and other trains acquire the same section to cause path conflict can be avoided.
Specifically, devices such as sections, platforms, or switches where the head yard vehicles are to be arranged on the route can be extracted.
Through the ATS system or the train operation plan, whether the route selected by other trains or the planned driving path contains equipment such as sections or switches contained in the routes to be arranged by the head-mounted train or not can be judged.
If yes, the common use of the equipment such as the section or the turnout and the like between the other trains and the head yard train is explained, and the route to be arranged of the current train conflicts with the route selected by the other trains or the planned driving route.
Devices such as common sections or switches may be referred to as overlapping devices.
If not, the fact that the other trains and the head yard train do not have the common use of equipment such as sections or turnouts does not exist, and the route to be arranged of the current train does not have a route conflict with the route selected by the other trains or the planned driving route.
Further, it is possible to determine whether other trains are located or will pass through the common facility according to the ATS system or the train operation plan. If the other trains are judged to be located or about to pass through the public equipment, the fact that the route to be arranged of the current train is in route conflict with the selected route or the planned driving route of the other trains is determined, namely the fact that the route selection conflict is generated on the route to be arranged of the current train is detected.
The embodiment of the invention can detect whether the route to be arranged of the current train conflicts with the route selected by other trains or the route planned to run by judging whether the route to be arranged of the head yard train and the route selected by other trains or the route planned to run have overlapping equipment, can detect that the route to be arranged of the current train conflicts with the route selected by other trains or the route planned to run, can avoid that the route selected by the head yard train and other trains impose the same section, can avoid the blockage in the track section, and can improve the running efficiency of the train.
Based on the content of the above embodiments, the specific step of determining whether the route to be scheduled of the current train conflicts with the routes selected by other trains or the planned travel routes, and whether the route conflicts exist, includes:
and if the current train is the planned train, acquiring a conflict node and a conflict train corresponding to the current train.
Specifically, the planning vehicle has already assigned a train operation plan, and the actual operation of the train is completed according to the train operation plan.
If the current train is determined to be the planning train, the equipment which is possibly in path conflict with other trains in the current train route to be arranged can be obtained according to the train operation plan of the current train and is used as a conflict node corresponding to the current train.
It should be noted that the equipment that the current train may collide with the other trains may include platform sections or switches.
And acquiring the conflict train corresponding to the current train according to the conflict node corresponding to the current train.
Specifically, according to the train operation plan, several trains that may collide with the current train at the collision node may be acquired as collision trains.
According to the conflict node and the conflict train corresponding to the current train, whether the path conflict exists in the route to be arranged of the current train can be detected.
And judging whether the conflict train is in a path from the current train to a conflict node corresponding to the current train.
Specifically, the physical location of the conflicting train at the current time may be obtained by the ATS system. And judging whether the conflict train is in a path from the current train to a conflict node corresponding to the current train or not according to the physical position of the conflict train at the current moment.
It should be noted that, if the collision node is a platform zone of a next station to be reached in front of the current train after the current train enters the to-be-scheduled route, the time when the current train and other trains reach the platform can be obtained through the ATS system or the current day plan of the train, and is used as the time when the current train and other trains reach the collision node.
If the conflict node is a turnout which is about to pass through in front after the current train drives into the route to be arranged, the nearest next station platform which can be reached by the passing turnout can be obtained according to the relevant equipment information of the turnout. The time when the current train and other trains arrive at the next station platform can be obtained through an ATS system or a current day plan of the train. According to the specific station type scene of the station platform, the offset is applied to the time of arriving at the next station platform, so that the time of arriving at the turnout to be passed by the current train or other trains can be obtained and used as the time of arriving at the conflict node by the current train or other trains.
It should be noted that the times when the train arrives, departs, or passes through the station may be obtained by the ATS system or the train operation plan, but the times when the train arrives at each switch may not necessarily be obtained. If the time when the train arrives at a certain switch needs to be obtained, the time can be obtained through indirect calculation in other ways, for example: the time when the train reaches the turnout can be calculated by obtaining the time when the train reaches the next station platform by the turnout and subtracting an offset from the time.
The offset can be determined according to the actual condition of train operation, for example: the distance between the next station platform and the turnout is divided by the running speed of the train. The specific value of the offset is not particularly limited in the present invention. According to the current train and the time when the conflict train reaches the conflict node, whether the conflict train is in the path from the current train to the conflict node corresponding to the current train or not can be judged.
If so, the conflict train arrives at the conflict node before the current train, and when the current train arrives at the conflict node, the conflict train does not drive away from the conflict node, and the conflict train is located in a path from the current train to the conflict node corresponding to the current train. If the current train enters the route to be arranged at the moment, the current train and the conflict train generate path conflict at the conflict node. Therefore, the method can detect that the route to be arranged of the current train generates route selection conflict.
If not, the conflict train arrives at the conflict node before the current train, and when the current train arrives at the conflict node, the conflict train already drives away from the conflict node, and the conflict train is not in the path from the current train to the conflict node corresponding to the current train. If the current train drives into the route to be arranged at the moment, the current train and the conflict train cannot generate path conflict at the conflict node. Therefore, the method can detect that the route to be arranged of the current train does not generate route selection conflict.
The embodiment of the invention aims at the condition that the current train is a planned train, acquires the conflict node and the conflict train corresponding to the current train according to the running plan of the current train, determines whether the route to be arranged of the current train has a route conflict with the route selected by other trains or the route planned to run by judging whether the conflict train is in the route from the current train to the conflict node corresponding to the current train or not, can detect that the route conflict can be generated on the route to be arranged of the current train, can avoid the same section being imposed on the route selected by the current train and other trains, can avoid the blockage in the track section, can improve the running efficiency of the train, can adapt to more actual running scenes of the train, and can overcome the route selection limit caused by a special station type.
Based on the content of the above embodiments, the specific step of acquiring the conflict node corresponding to the current train includes: and acquiring equipment overlapped in the route to be arranged of the current train and the planned driving route of the previous train of the current train as a collision node corresponding to the current train.
Specifically, the device such as a route, a switch, or a platform included in the route to be scheduled of the current train is extracted.
According to the ATS system or the train operation plan, it is possible to determine whether or not a preceding train of the current train includes equipment included in a route to be scheduled with the current train in a route planned to be traveled.
If yes, the fact that the current train and the previous train are shared is shown, the shared equipment is the equipment which is overlapped in the route to be arranged of the current train and the planned driving route of the previous train of the current train, and the overlapped equipment is determined as the corresponding conflict node of the current train.
The device overlapped with the planned driving path of the previous train in the route to be arranged of the current train can be a turnout to be passed by in front of the current train, or a platform section of the next station and the like.
The ATS system or the train operation plan may obtain the relevant device information of the collision node corresponding to the current train, for example: if the conflict node is a turnout, the nearest next station and platform which can be reached through the turnout can be obtained, and related equipment information such as the distance between the turnout and the platform can be obtained.
According to the embodiment of the invention, through an ATS system or a train operation plan, the equipment overlapped in the current train route to be arranged and the current train front train plan running is obtained, the conflict node corresponding to the current train can be determined, the relevant equipment information of the conflict node corresponding to the current train can be obtained, and a data basis can be provided for obtaining the conflict train and detecting whether the current train route to be arranged has a path conflict.
Based on the content of the above embodiments, the specific steps of the conflict train corresponding to the current train include: and acquiring a train which passes through the conflict node and has the physical position closest to the current train in the front train of the current train, and taking the train as the conflict train corresponding to the current train.
Specifically, traversing all train operation plans on the current day, and screening out a planned train meeting the following conditions from the trains ahead of the current train, wherein the planned train comprises:
1. the planned route of the train is a conflict node;
2. the train leaves the previous station but does not reach the conflict node, wherein the previous station is the previous station corresponding to the conflict node in the train running path;
3. the time when the train plan reaches the conflict node is earlier than the time when the current train plan reaches the conflict node;
4. the time when the train plan arrives at the conflict node is closest to the time when the current train plan arrives at the conflict node.
It should be noted that, when the current train triggers the route to be scheduled, the front train of the current train refers to the train whose physical position is located before the current train driving direction in the route within a certain range communicated with the route to be scheduled of the current train. The range may be a range of paths within the current train and the route start to the route end of the train.
When the train runs in a special station type or special running scene, the front train not only can be a train which is always positioned in front of the current train and runs, but also can be turned back in the station or switched in the path, and the like, and becomes the front train of the current train after the current train triggers the path to be arranged.
And after the planned trains meeting the requirements are screened out, acquiring a planned train with the physical position closest to the current train according to the physical position of the planned train, and taking the planned train as a conflict train corresponding to the current train.
The ATS system may acquire relevant information of a conflict train corresponding to the current train, for example: the physical location of the colliding train, the speed per hour of the colliding train, etc.
According to the conflict node corresponding to the current train, the conflict train corresponding to the current train can be determined by acquiring the previous train which passes through the conflict node and is closest to the current train in physical position, the relevant information of the conflict train corresponding to the current train can be acquired, and a data basis can be provided for detecting whether the route to be routed of the current train has the route conflict.
Based on the content of the above embodiments, the time difference between the scheduling time and the selection timing of the route to be scheduled of the current train is greater than the preset time threshold.
Specifically, for the outbound route and the folded outbound route, whether a route selection conflict occurs between the route to be selected of the current train and other trains is detected, and the detection can be realized by judging whether the time difference between the selection time of the route to be selected of the current train and the planning time is greater than a preset time threshold.
Whether the time difference between the scheduling opportunity and the selecting opportunity of the current route to be scheduled of the train is greater than a preset time threshold or not can be judged: the selection and arrangement time of the current route to be arranged of the train is earlier than the planning time and the selection and arrangement time of the current route to be arranged of the train is later than the planning time.
And if the scheduling time of the current route to be scheduled of the train is earlier than the scheduling time and the time difference between the scheduling time and the scheduling time is greater than a preset time threshold, indicating that the current train drives into the route to be scheduled in advance. At this time, other trains have not completed technical work in the route to be arranged of the current train, and after the current train enters the route to be arranged, a path conflict occurs between the current train and the train in the route to be arranged.
If the time for selecting the route to be scheduled of the current train is later than the planning time and the time difference between the time for selecting the route to be scheduled and the planning time is larger than the preset time threshold, it is indicated that the current train delays to enter the route to be scheduled, the current train delays to exit the route to be scheduled, and at the moment, other trains enter the route to be scheduled according to the original plan and conflict with the current train in the route to be scheduled of the current train.
It should be noted that the preset time threshold may be determined according to the actual running condition of the train, for example: the time required by the train passing through the route is planned before the current train enters the route to be arranged, or the time required by the current train to finish the preset operation in the route to be arranged is reserved. The specific value of the preset time threshold is not specifically limited in the embodiment of the present invention.
According to the embodiment of the invention, for the outbound route and the folded route, whether the time difference between the scheduling time and the selection time of the current route to be arranged of the train is greater than the preset time threshold value or not can be judged, the route selection conflict between the route to be selected of the current train and other trains can be detected, the condition that the same section is imposed on the route selected by the current train and other trains can be avoided, the blockage in the track section can be avoided, and the train operation efficiency can be improved.
The following describes an application of the method for detecting a routing conflict in practice by using an example. Fig. 2 is a schematic diagram of an actual application of the method for detecting a route selection conflict according to the embodiment of the present invention, and as shown in fig. 2, the actual application scenario relates to a train a, a train B, a platform a, a platform B, and signal apparatuses X01, X02, X03, S02, and S04.
The method comprises the steps that a train A and a train B are planning trains, and whether a route to be arranged of the train A generates a route selection conflict or not is detected.
The operation plan of the train A is that the train A starts from X01, runs to the platform B and turns back before the station, and the route selected by the train A is X01-S02.
The operation plan of the train B is that the train B starts from X02, runs to a return rail to be stopped and then returns to a platform B, and the planned running path of the train B is X02-X03-S02.
The time at which train B is planned to reach platform B is earlier than the time at which train a is planned to reach platform B, and no other trains are planned to pass through platform B.
As can be seen from the above description, if the overlapped device in the route to be scheduled by the train a and the planned travel route of the train B is the platform B, it can be determined that the platform B is the collision node corresponding to the train a.
As can be seen from the above description, the train B may be referred to as the lead train of the train a, and the following conditions are satisfied:
1. planning the train B to pass through a platform B;
2. the train B leaves the last station but does not arrive at the platform B;
3. the time when the train B plans to arrive at the platform B is earlier than the time when the train A plans to arrive at the platform B;
4. the time at which train B is scheduled to arrive at platform B is closest to the time at which train a is scheduled to arrive at platform B.
Thus, it can be determined that train B is the conflicting train for train a.
And judging whether the train B is in the path between the train A and the platform B according to the physical position of the train B.
Since the train B does not reach the platform B and is in the path between the train a and the platform B, the route selection conflict is generated when detecting the to-be-arranged route X01-S02 of the train a.
