Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
Fig. 1 is a schematic flow chart of a rail transit map collision detection method. Referring to fig. 1, an embodiment of the present application provides a method for detecting a track traffic diagram conflict, which may include the steps of:
s1, acquiring basic data of a train operation model and an operation diagram to be tested; further, the train operation model basic data comprises line data, vehicle model data and train control model data;
s2, dividing the train running route corresponding to the running chart to be tested into a plurality of subareas;
s3, according to the arrival and departure time of the station of each train number in the running chart to be tested and based on the basic data of the train running model, carrying out train simulation running, and recording and calculating the occupation time information of each train in each subarea;
and S4, judging that the running chart to be tested has conflict when the occupation time of different trains in the same subarea is overlapped according to the occupation time information.
In the embodiment of the application, relevant data (train operation model basic data) of train operation and an operation diagram to be tested are firstly obtained, and the obtained data can be determined according to the data requirements of subsequent train simulation operation, such as line data, vehicle model data and train control model data, wherein the line data comprises main factors such as line equipment arrangement, gradient, speed limit and the like, and the data are objective limiting factors influencing the advancing line of a train; the vehicle model data is mainly used for simulating real running states of the train after receiving the control command, such as traction force, braking force and the like; the train control model data mainly simulates the control principle of a train control system, for example, determining when to give a command to a train. The data of the running chart to be tested are mainly used for describing information such as the traveling direction of each train number, the arrival and departure time of the approach station and the like.
Then, the train running route corresponding to the running chart to be tested is divided into a plurality of subareas, and the division can be based on the section type (access road, track circuit), the train safety length and the like. It will be appreciated that the partitioned divisions are sequential and unique in sequence along the train direction of travel.
After the subareas are divided, train simulation operation is carried out according to the arrival and departure time of the station of each train number in the running chart to be tested and the basic data of the train operation model, and the occupation time information of each train in each subarea can be recorded and calculated in the process of operation. For example, the time when the train enters and leaves a certain base station can be directly acquired, and a certain time length is added at the head and the tail on the basis of the time to ensure the operation safety.
And after the occupation time information of each train in each subarea corresponding to the operation diagram is obtained through calculation, judging whether the operation diagram conflicts or not according to whether the occupation times of a plurality of trains overlap or not in the same subarea. The corresponding occupation time map can be generated according to the occupation time information, so that a user can observe the occupation time conditions of each subarea more intuitively, for example, the density between the occupation times of different trains in the same subarea and the like, and the subarea with time conflicts can be found more intuitively.
According to the rail transit working diagram conflict detection method provided by the embodiment of the application, the whole train working route is divided into the subareas, the continuous subareas are used as the basis of time conflict detection, and the occupied time detailed data of each subarea in the running process of the train is recorded and calculated in a simulation model train running mode, so that the conflict situation of the working diagram can be detected more accurately and more comprehensively, and the validity and reliability of the working diagram conflict detection are effectively improved.
In one embodiment, step S2 may include:
determining a dividing factor according to a blocking system of the train operation route, acquiring demarcation point information of the train operation route based on the dividing factor, and dividing the train operation route into a plurality of subareas based on the demarcation point information; wherein the partition factors include one or more of train safety length, route and track circuit section.
In the embodiment of the application, different partitioning strategies are configured in a targeted manner according to the blocking systems corresponding to different lines to perform partitioning, specifically, different partitioning factors (for example, a track circuit section is used as a partitioning factor) are determined according to different blocking systems of a train running line, specific demarcation points on the running line are obtained according to the determined partitioning factors, and finally partitioning is performed based on the demarcation points, for example, a road section between every two adjacent demarcation points is used as a partition. The rail transit operation diagram conflict detection method provided by the embodiment of the application can enable the divided partitions to reflect the characteristics of the line better, so that the authenticity of subsequent simulation operation is effectively improved, and the accuracy, effectiveness and reliability of operation diagram conflict detection are further improved.
In one embodiment, step S3 may include:
and performing train simulation operation according to the arrival and departure time of the station of each train number in the to-be-detected operation diagram and based on the train operation model basic data, recording the monitoring and marking time of each train in each subarea, and expanding the monitoring and marking time according to a preset time composition format to generate the occupation time information of each train in each subarea.
It should be noted that, when generating the occupation time information of each train in each partition, the time monitored in the simulation operation process may be recorded first, for example, the time information of the time when the train enters the partition or leaves the partition may be obtained by directly monitoring the marker, and based on the fixed time information, the occupation time information of the train in the partition is further expanded and filled to generate. In this embodiment, the time expansion filling is performed by using a preset time composition format as a frame and combining the basic data of the train operation model to generate and obtain the final occupied time information.
In the embodiment of the present application, the time composition format may include three stages, namely, a partition application stage, a partition occupation stage, and a partition resource release stage; the subarea application stage mainly comprises signal system reaction time, driver reaction time and train approaching time, the subarea occupation stage comprises running time and clearing time in a locomotive subarea, and the subarea resource release stage comprises resource release time.
It can be understood that the occupation time information of each partition finally generated according to the time composition format mainly includes three stages: application, use and release of the medicine are carried out,
wherein, the application stage refers to: in the running process of the train, the occupation of the subareas needs to be applied in advance, and the train head reaches the edge position of the subareas through the signal system reaction time, the driver reaction time and the approach time. The use phase refers to: the trains physically occupy the zones, corresponding to "run time in head zone" and "departure time", where "departure time" is the time from when the head of the train leaves the zone range to when the tail of the train leaves the zone range, after which the trains no longer physically occupy the zone. The release phase refers to: from the end of the train leaving the zone range to the time the system confirms that the zone is free and can be reapplied. It should be noted that "signal system response time", "driver response time", and "resource release time" are mainly determined by the train control model; the "approach time", "operation time in the locomotive zone" and "departure time" are mainly influenced by the train operation speed.
According to the track traffic working diagram conflict detection method provided by the embodiment of the application, the occupation time information of the train in each subarea is subdivided into three stages/six components, the time-use situation of smaller time granularity of the train in each subarea can be displayed through the occupation time result, and the subarea occupation time can be analyzed and adjusted according to different stages/links, so that the reliability of working diagram conflict detection is further improved, and the pertinence and the accuracy of train operation analysis are effectively improved.
In one embodiment, the rail transit map collision detection method may further include the steps of:
and when the occupation time of different trains in the same subarea is judged to be overlapped according to the occupation time information, generating an adjusting scheme according to the occupation time information corresponding to the overlapped part. Further, the adjustment scheme includes any one of:
adjusting the line limiting speed of the corresponding subarea with overlapped occupied time;
and adjusting the departure time of the corresponding train with the overlapped occupation time.
In the embodiment of the application, after the occupation time information of all the zones of all the trains corresponding to the operation diagram is obtained, if the occupation times of different trains in the same zone are overlapped, the occupation time information delta T of the overlapped part is obtained, and a corresponding train operation adjusting scheme is generated according to the delta T so as to overcome the operation conflict situation. Wherein, can adjust through following two kinds of modes: 1. adjusting the line limiting speed of the corresponding subarea with overlapped occupied time; 2. and adjusting the departure time of the corresponding train with the overlapped occupation time. It should be noted that "signal system response time", "driver response time", and "resource release time" are mainly determined by the train control model; the "approach time", "operation time in the locomotive zone" and "departure time" are mainly influenced by the train operation speed. Because the train and the control system are set factors, the train and the control system are not adjusted by modifying the train control model, and the speed can be limited by modifying the line of the corresponding subarea, so that the running speed of the train in the subarea is improved, and the running time is shortened to achieve the purpose of adjustment; in addition, when the subarea is a platform, the time for the train to stop at the platform can be appropriately shortened according to the actual operation condition, so that the time for the train to stop at the subarea can be shortened, and the aim of adjustment can be achieved. In addition, the departure times of the corresponding trains with overlapping occupancy times may be adjusted, for example, for two trains with overlapping occupancy times, the departure time of the first train may be advanced, the departure time of the second train may be delayed, or both the departure time of the first train and the departure time of the second train may be advanced. It is understood that the above 1 st adjustment scheme or 2 nd adjustment scheme may be executed separately, or when 1 of the adjustment schemes is executed separately, the two adjustment schemes may be executed simultaneously.
It should be noted that, the 1 st adjustment scheme is implemented by adjusting the speed limit of the route, and therefore, may have a certain influence on the operation safety of the train, and the 1 st adjustment scheme needs to be generated according to the safe operation parameters of the train as the constraint condition. The 2 nd adjustment scheme is realized by advancing/postponing the departure time of the train, and since the actual occupied time of all the zones changes after the departure time of the train is adjusted, a new occupied time conflict situation may occur after the adjustment scheme is executed this time, and thus, other trains need to be continuously adjusted correspondingly, and therefore, the problem of a large adjustment range is faced if the 2 nd adjustment scheme is adopted.
According to the rail transit running chart conflict detection method provided by the embodiment of the application, the occupied time of the subareas generated according to the simulation running calculation is utilized, when the overlapping of the occupied time is judged, the corresponding adjusting scheme is automatically generated according to the overlapping time, so that the problem of running chart conflict is solved, two adjusting schemes are provided according to the actual situation for comprehensive adjustment, the running safety and the adjusting feasibility of a train can be ensured, and the effectiveness and the reliability of running chart conflict detection can be further exerted.
With reference to fig. 2 to fig. 6, based on the above solutions, in order to better understand the method for detecting a conflict of a track traffic diagram provided in the embodiment of the present application, the following specific description is provided:
the purpose of the embodiment of the application is as follows: according to the UIC406 theory, the track traffic signal control characteristics are combined, the line is reasonably partitioned, the train occupation time of each partition of the line is obtained through the simulation operation of the operation diagram, the partition occupation conflict information is further obtained through calculation, the operation diagram conflict detection function of the whole line is realized, the conflict position and the conflict time difference are visually displayed, and data support is provided for further analysis and adjustment of the operation diagram.
Referring to fig. 2, in the embodiment of the present application, UIC406 is used as a theoretical basis, a rail transit line is divided into continuous independent partitions, train simulation operation is performed according to a running chart, occupation time of a train in each partition is obtained through calculation, and a purpose of detecting a running chart conflict is achieved according to whether a partition occupation conflict exists. The specific implementation flow is as follows:
load data
1. Line data: the method mainly comprises the steps of determining objective limiting factors of a traveling route of the train, such as route equipment arrangement, gradient, speed limit and the like;
2. vehicle model data: the simulation system is mainly used for simulating the real running state of the train after receiving the control instruction;
3. a train control model: the train control system is mainly used for simulating the control principle of the train control system and determining when to give out commands to the train;
the above are main factors influencing the operation of the train on the line, and therefore, in order to more accurately simulate the operation process of the train so as to calculate the occupied time of the train partition more accurately in the following, the above 3 kinds of data need to be loaded as the basis of the following simulation operation and calculation.
Reading the operation chart data
The operation diagram data is mainly used for describing information such as the traveling direction of each train and the arrival and departure time of a route station, wherein the time can be represented in a horizontal direction, and the station can be represented in a vertical direction (including the arrival and departure time of each train at the station).
Line partition
As shown in fig. 3, the train traveling route is sequentially divided into a plurality of consecutive independent zones according to the train traveling direction. The size of the subareas can be divided according to the factors such as the safe length of the train (considering speed measurement and distance measurement errors), the approach, the circuit section of the track and the like according to different block systems.
Fourthly, simulating the operation of the train and calculating the occupied time of the subareas
1. Time composition of occupied subareas during train operation
As shown in fig. 4, on the basis of UIC406 as a theoretical basis, the occupation time component of each partition can be divided into 6 parts, including "signal system reaction time", "driver reaction time", "approach time", "runtime in the locomotive partition", "departure time", and "resource release time".
As can be seen from fig. 4, the occupation of the subareas during the train operation can be divided into 3 stages: application, use and release; wherein:
a) applying for: in the running process of the train, the regional occupation needs to be applied in advance, and the train head reaches the edge position of the regional area after three time periods of 'signal system reaction time', 'driver reaction time' and 'approach time'.
b) Use of: the trains physically occupy zones, corresponding to "run time in locomotive zone" and "departure time" in fig. 4. Wherein the 'departure time' is the time from the departure of the train head from the zone range to the departure of the train tail from the zone range, after which the train no longer physically occupies the zone.
c) Releasing: from the end of the train leaving the zone range to the time the system confirms that the zone is free and can be reapplied.
2. Train simulation operation and calculation
According to the running path and the arrival and departure time of each train number in the operation diagram, the train operation is simulated based on the line data, the vehicle model data and the train control model data, the occupation time of each train in each subarea is recorded and calculated in the operation process, and the occupation time diagram of continuous subareas can be formed according to the occupation time information, as shown in fig. 5, each columnar area is the occupation time of one train in one subarea, and each columnar area comprises the 6 time period components.
Fifth, detection of conflict of operation diagram
The data of the partition occupation time of all train numbers on the path of the operation diagram are obtained in the steps, and the computer is used for comparing and calculating partition by partition one by one to analyze whether the same partition is occupied by a plurality of trains at the same time (the occupation time of different trains in the same partition is overlapped) so as to judge whether the operation diagram conflicts in the partition. Specifically, the method comprises the following steps:
1. run chart conflict detection results
As shown in fig. 6, the trains 1 and 2 start simulation operation according to departure times t1 and t2 of the operation diagrams respectively, and the result shows that the situation that the partition 1 and the partition 2 are occupied by multiple trains simultaneously does not exist, and the situation that the partition 3 is occupied by two trains simultaneously exists, then the conclusion of the operation diagram collision detection can be obtained: the runtime map has a conflict, the conflict location being partition 3.
2. Further support conflict analysis and runtime graph adjustment
As can be seen from FIG. 6, the time that the train 1 occupies the zone 3 is T1- > T3, the time that the train 2 occupies the zone 3 is T2- > T4,
the collision time Δ T of the two vehicles in the partition 3 is T3-T2.
Thus, the following protocol adjustments can be provided for the run graph through conflict analysis:
a) postponing departure time T2 of the train 2 by delta T; or the departure time T1 of the train 1 is advanced by the amount of time delta T;
b) the occupation time of the partition 3 is shortened.
Since the partition occupation time is composed of six parts as shown in fig. 4. Wherein, the 'signal system reaction time', 'driver reaction time' and 'resource release time' are mainly determined by the train control model; the "approach time", "operation time in the locomotive zone" and "departure time" are mainly influenced by the train operation speed.
Adjustment (1): because the train and the control system are set factors, the train and the control system are not adjusted by modifying the train control model, and the speed can be limited by modifying the line of the subarea 3, so that the running speed of the train in the subarea 3 is improved, and the running time of the train in the subarea is shortened to achieve the purpose of adjusting.
In the case that the partition 3 is a platform, the time for the train to stop at the platform can be appropriately shortened according to the actual operation situation to achieve the purpose of adjustment.
Adjustment (2): if the conflict problem can not be overcome even if the time delta T is shortened by the adjustment (1), the departure time T2 of the train 2 can be properly delayed on the basis of the adjustment (1), and the aim of adjustment is comprehensively achieved.
It should be noted that the existing related schemes either only apply the UIC406 to the railway field or only calculate the UIC406 capacity under the limited blocking system. A method for detecting the conflict of the train operation diagram based on the UIC406 and not limited by a blocking system in the rail transit field does not exist.
Compared with the prior art, the method for detecting the conflict of the rail transit working diagram is provided, a train running line is divided into a plurality of independent path units according to the UIC406 theory, the running of a train is simulated through a simulation system according to the train working diagram, the detailed time composition of each path unit occupied in the running process of each train is calculated, the conflict detection of the working diagram is realized and the result is visually displayed on the basis that the same path unit is not allowed to be occupied by multiple trains at the same time, and meanwhile, support is provided for the adjustment of the subsequent working diagram, so that the effectiveness and the reliability of the conflict detection of the working diagram are effectively improved.
