[0038] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0039] Figure 1 The figure is a flow chart of the conflict detection method for the rail transit operation diagram. Figure 1 The present application embodiment provides a rail transit operation diagram conflict detection method, which may include the following steps:
[0040] S1. Obtaining basic data of a train operation model and a running diagram to be tested; further, the basic data of the train operation model includes line data, vehicle model data and train control model data;
[0041] S2, dividing the train running route corresponding to the running diagram to be tested into a plurality of partitions;
[0042] S3, performing train simulation operation according to the station arrival and departure time of each train in the operation diagram to be tested and based on the basic data of the train operation model, recording and calculating the occupancy time information of each train in each section;
[0043] S4. When it is determined according to the occupation time information that the occupation times of different trains in the same section overlap, it is determined that there is a conflict in the operation diagram to be tested.
[0044] In the embodiment of the present application, firstly, the relevant data of the train operation (the basic data of the train operation model) and the operation diagram to be tested are obtained. The data to be obtained can be determined according to the data requirements of the subsequent train simulation operation, such as line data, vehicle model data and train control model data, wherein the line data includes the main factors such as line equipment layout, slope, speed limit, etc., which are objective limiting factors affecting the train's route; the vehicle model data is mainly used to simulate the actual operating state of the train after receiving the control command, such as traction, braking force, etc.; the train control model data mainly simulates the control principle of the train control system, such as deciding what command to issue to the train at what time. The operation diagram data to be tested is mainly used to describe information such as the travel direction of each train and the arrival and departure time of the stations passed through.
[0045] Then, the train running route corresponding to the running diagram to be tested is divided into several partitions, which can be based on the section type (approach, track circuit), train safety length, etc. It can be understood that the divided partitions are continuous and unique in sequence along the train running direction.
[0046] After the partitions are divided, the train simulation operation is performed according to the station arrival and departure times of each train in the test operation diagram and the basic data of the train operation model. During the process of traveling, the occupied time information of each train in each partition can be recorded and calculated. For example, the time when the train enters and leaves a certain base station can be directly obtained, and a certain time can be added to the head and tail based on this time to ensure operation safety.
[0047] After calculating the occupancy time information of each train in each partition corresponding to the operation diagram, whether there is a conflict in the operation diagram is determined based on whether there is overlap in the occupancy time of multiple trains in the same partition. The corresponding occupancy time diagram can be generated based on this occupancy time information, so that users can more intuitively observe the occupancy time of each partition, such as the density of occupancy time of different trains in the same partition, and can also more intuitively find partitions with time conflicts.
[0048] The rail transit operation diagram conflict detection method provided in the embodiment of the present application divides the entire train operation route into zones and uses continuous zones as the basis for time conflict detection. At the same time, a simulation model train operation method is used to record and calculate detailed data on the occupancy time in each zone during the train's travel. This makes it possible to detect the conflict situation of the operation diagram more accurately and comprehensively, effectively improving the effectiveness and reliability of the operation diagram conflict detection.
[0049] In one embodiment, step S2 may include:
[0050] Determine the division factors according to the block system of the train route, obtain the demarcation point information of the train route based on the division factors, and then divide the train route into a number of partitions based on the demarcation point information; wherein the division factors include one or more of the train safety length, route and track circuit section.
[0051] In the embodiment of the present application, different partitioning strategies are configured according to the block systems corresponding to different lines to perform partitioning. Specifically, different partitioning factors are determined according to the different block systems of the train running routes (for example, the track circuit section is used as the partitioning factor), and specific demarcation points on the running line are obtained according to the determined demarcation factors. Finally, partitioning is performed based on these demarcation points, for example, the section between each two adjacent demarcation points is regarded as a partition. The rail transit operation diagram conflict detection method provided in the embodiment of the present application can make the divided partitions better reflect the characteristics of the line, thereby effectively improving the authenticity of the subsequent simulation operation, and further improving the accuracy, effectiveness and reliability of the operation diagram conflict detection.
[0052] In one embodiment, step S3 may include:
[0053] According to the station arrival and departure times of each train in the operation diagram to be tested, and based on the basic data of the train operation model, a train simulation operation is performed, and the monitoring mark time of each train in each section is recorded, and then the monitoring mark time is expanded according to a preset time composition format to generate the occupancy time information of each train in each section.
[0054] It should be noted that when generating the occupancy time information of each train in each partition, the time monitored during the simulation operation can be recorded first. For example, the time information of the moment when the train enters or leaves the partition can be directly monitored and marked. On the basis of these fixed time information, further expansion and filling are performed to generate the occupancy time information of the train in the partition. In this embodiment, the expansion and filling of time is based on the preset time composition format as a framework, combined with the aforementioned basic data of the train operation model, to generate the final occupancy time information.
[0055] In an embodiment of the present application, the time composition format may include three stages: partition application stage, partition occupation stage and partition resource release stage; wherein the partition application stage mainly includes the signal system reaction time, the driver reaction time and the train approach time, the partition occupation stage includes the running time in the front partition and the clearing time, and the partition resource release stage includes the resource release time.
[0056] It can be understood that the occupation time information of each partition generated in the time composition format mainly includes three stages: application, use, and release.
[0057] Among them, the application stage refers to: during the operation of the train, it is necessary to apply for the occupation of the partition in advance, and after the "signal system reaction time", "driver reaction time" and "approach time", the front of the train reaches the edge of the partition. The use stage refers to: the train physically occupies the partition, corresponding to the "front running time in the partition" and "clearing time", among which the "clearing time" is the time from the front of the train leaving the partition range to the rear of the train leaving the partition range. After that, the train no longer physically occupies the partition. The release stage refers to: the time from the rear of the train leaving the partition range to the system confirming that the partition is free and can be applied for again. It should be noted that the "signal system reaction time", "driver reaction time" and "resource release time" are mainly determined by the train control model; the "approach time", "front running time in the partition" and "clearing time" are mainly affected by the train running speed.
[0058] The rail transit operation diagram conflict detection method provided in the embodiment of the present application, by subdividing the train occupancy time information in each section into three stages / six components, can display the train's time usage in each section at a smaller time granularity through the occupancy time results, and can analyze and adjust the section occupancy time according to different stages / links, thereby further improving the reliability of the operation diagram conflict detection and effectively improving the pertinence and accuracy of the train operation analysis.
[0059] In one embodiment, the rail transit operation diagram conflict detection method may further include the steps of:
[0060] When it is determined based on the occupation time information that the occupation times of different trains in the same section overlap, an adjustment plan is generated based on the occupation time information corresponding to the overlapping parts. Further, the adjustment plan includes any one of the following:
[0061] Adjust the line speed limits of corresponding sections where the occupancy times overlap;
[0062] The departure time of corresponding trains whose occupied time overlaps will be adjusted.
[0063] In the embodiment of the present application, after obtaining the occupation time information of all trains in all partitions corresponding to the operation diagram, if the occupation time of different trains in the same partition overlaps, the occupation time information △T of the overlapping part is obtained, and the corresponding train operation adjustment plan is generated according to △T to overcome this operation conflict. Among them, the adjustment can be made in the following two ways: 1. Adjust the line speed limit of the corresponding partition where the occupation time overlaps; 2. Adjust the departure time of the corresponding train where the occupation time overlaps. It should be noted that "signal system reaction time", "driver reaction time" and "resource release time" are mainly determined by the train control model; "approach time", "head section operation time" and "clearing time" are mainly affected by the train running speed. Since the train and control system are established factors, they should not be adjusted by modifying the train control model. The line speed limit of the corresponding partition can be modified to increase the running speed of the train in the partition, and then shorten the running time to achieve the purpose of adjustment; in addition, for the case where the partition is a platform, the train stop time at the platform can also be appropriately shortened according to the actual operation situation, thereby shortening the train's stay time in the partition, so as to achieve the purpose of adjustment. In addition, the departure time of the corresponding trains with overlapping occupancy times can be adjusted. For example, for two trains with overlapping occupancy times, the departure time of the first train can be advanced, the departure time of the second train can be postponed, or the departure time of the first train can be advanced and the departure time of the second train can be postponed at the same time. It can be understood that the first adjustment scheme or the second adjustment scheme can be executed separately, or when executing one of the adjustment schemes alone cannot solve the operation conflict problem, both adjustment schemes can be executed simultaneously.
[0064] It should be noted that the first adjustment scheme is achieved by adjusting the line speed limit, so it may have a certain impact on the safety of train operation. When generating the first adjustment scheme, the safe operation parameters of the train need to be used as constraints. The second adjustment scheme is achieved by advancing / delaying the departure time of the train. After adjusting the departure time of the train, the actual occupancy time of all sections will change. Therefore, it is possible that after the implementation of this adjustment scheme, new occupancy time conflicts will occur, so other trains need to be adjusted accordingly. Therefore, if the second adjustment scheme is adopted, the adjustment range will be too large.
[0065] The rail transit operation diagram conflict detection method provided in the embodiment of the present application utilizes the partition occupancy time generated according to the simulation operation calculation. When it is determined that the occupancy time overlaps, a corresponding adjustment plan is automatically generated according to the overlapping time to overcome the problem of operation diagram conflict, and two adjustment plans are provided for comprehensive adjustment according to the actual situation, which can ensure the safety of train operation and the feasibility of adjustment, thereby further enhancing the effectiveness and reliability of operation diagram conflict detection.
[0066] Please combine Figures 2 to 6 Based on the above scheme, in order to better understand the rail transit operation diagram conflict detection method provided in the embodiment of the present application, the following is a specific description:
[0067] The purpose of the embodiment of the present application is to reasonably divide the line into zones according to UIC406 theory and in combination with the characteristics of rail transit signal control, obtain the train occupancy time of each zone of the line through simulation and operation of the operation diagram, and further calculate the zone occupancy conflict information, so as to realize the operation diagram conflict detection function of the whole line, and intuitively display the conflict position and conflict time difference, so as to provide data support for further analysis and adjustment of the operation diagram.
[0068] See also Figure 2 The embodiment of the present application takes UIC406 as the theoretical basis, divides the rail transit line into continuous independent partitions, performs train simulation operation according to the operation diagram, calculates the train occupancy time in each partition, and realizes the purpose of operation diagram conflict detection based on whether there is a partition occupancy conflict. The specific implementation process is as follows:
[0069] 1. Loading data
[0070] 1. Line data: mainly includes objective limiting factors that determine the train's route, such as line equipment layout, slope, speed limit, etc.;
[0071] 2. Vehicle model data: mainly used to simulate the actual running status of the train after receiving the control command;
[0072] 3. Train control model: mainly used to simulate the control principle of the train control system and decide when to issue what instructions to the train;
[0073] The above are the main factors that affect the operation of trains on the line. Therefore, in order to simulate the operation process of the train more accurately and to calculate the occupancy time of the train section more accurately later, it is necessary to load the above three types of data as the basis for subsequent simulation operation and calculation.
[0074] 2. Reading operation diagram data
[0075] The operation diagram data is mainly used to describe the travel direction of each train and the arrival and departure time of the stations it passes through, among which time can be represented horizontally and stations can be represented vertically (including the arrival and departure time of each train at the station).
[0076] 3. Line Division
[0077] like Figure 3 As shown in the figure, the train route is divided into several continuous and independent sections in order according to the train running direction. The size of the section can be divided according to the safety length of the train (considering the speed and distance measurement error), route, track circuit section and other factors according to different block systems.
[0078] 4. Train simulation operation and calculation of partition occupancy time
[0079] 1. Time composition of train operation occupying zones
[0080] like Figure 4 As shown, based on UIC406, the occupancy time of each partition can be divided into six parts, including "signal system reaction time", "driver reaction time", "approach time", "operating time in the front partition", "clearing time" and "resource release time".
[0081] from Figure 4 It can be seen that during the operation of the train, the occupation of the partition can be divided into three stages: application, use, and release; among them:
[0082] a) Application: During the operation of the train, it is necessary to apply for zone occupancy in advance. After the three periods of "signal system reaction time", "driver reaction time" and "approach time", the train head reaches the edge of the zone.
[0083] b) Use: The train physically occupies the partition, corresponding to Figure 4 The "front running time in the partition" and "clearing time" of the train are calculated. Among them, the "clearing time" is the time from the front of the train leaving the partition to the rear of the train leaving the partition. After that, the train no longer physically occupies the partition.
[0084] c) Release: The time from when the rear of the train leaves the partition to when the system confirms that the partition is free and can be applied for again.
[0085] 2. Train simulation operation and calculation
[0086] According to the running path and station arrival and departure time of each train in the operation diagram, the train operation is simulated based on the line data, vehicle model data and train control model data. During the operation, the occupancy time of each train in each partition is recorded and calculated. The occupancy time diagram of the continuous partition can be formed based on the occupancy time information, such as Figure 5As shown, each columnar area is the occupancy time of a train in a partition, and each columnar area includes the above-mentioned 6 time period components.
[0087] 5. Run Graph Conflict Detection
[0088] In the above steps, the partition occupancy time data of all trains on the operation diagram path is obtained. Through the computer, the partition-by-partition comparison operation is performed to analyze whether the same partition is occupied by multiple trains at the same time (the occupancy time of different trains in the same partition overlaps), and then determine whether there is a conflict in the operation diagram in this partition. Specifically:
[0089] 1. Run the graph conflict detection results
[0090] like Figure 6 As shown, train 1 and train 2 start simulation operation according to the departure times t1 and t2 of the operation diagram respectively. The results show that partition 1 and partition 2 are not occupied by multiple trains at the same time, and partition 3 is occupied by two trains at the same time. Therefore, the conclusion of the operation diagram conflict detection can be drawn: there is a conflict in the operation diagram, and the conflict location is partition 3.
[0091] 2. Further support for conflict analysis and operation diagram adjustment
[0092] Depend on Figure 6 It can be seen that the time that train 1 occupies partition 3 is T1->T3, and the time that train 2 occupies partition 3 is T2->T4.
[0093] The conflict time between the two vehicles in zone 3 is △T=T3-T2.
[0094] Therefore, the following scheme adjustments can be provided for the operation diagram through conflict analysis:
[0095] a) Delay the departure time of train 2 by t2, the delay time is △T; or advance the departure time of train 1 by t1, the advance time is △T;
[0096] b) Shorten the occupation time of partition 3.
[0097] Since the partition occupancy time is determined by Figure 4 The six parts are shown in the figure. Among them, "signal system reaction time", "driver reaction time" and "resource release time" are mainly determined by the train control model; "approach time", "head section operation time" and "clearing time" are mainly affected by the train running speed.
[0098] Adjustment (1): Since the train and control system are fixed factors, they should not be adjusted by modifying the train control model. The adjustment purpose can be achieved by modifying the line speed limit of section 3, thereby increasing the train running speed in section 3 and then shortening the train running time in this section.
[0099] If zone 3 is a platform, the train's stop time at the platform can be appropriately shortened to achieve the purpose of adjustment based on the actual operation situation.
[0100] Adjustment (2): If the conflict problem cannot be overcome by shortening the △T time through adjustment (1), the departure time t2 of Train 2 can be appropriately postponed on the basis of adjustment (1) to achieve the purpose of adjustment comprehensively.
[0101] It should be noted that the existing related solutions only apply UIC406 to the railway field, or only calculate the UIC406 capacity under a limited block system. There is no method for train operation diagram conflict detection based on UIC406 in the field of rail transportation that is not restricted by the block system.
[0102] Compared with the prior art, the embodiment of the present application provides a rail transit operation diagram conflict detection method. According to the UIC406 theory, the train operation line is divided into several independent path units. According to the train operation diagram, the operation of the train is simulated by a simulation system, and the detailed time composition of each path unit occupied by each train during the operation is calculated. Based on the fact that the same path unit is not allowed to be occupied by multiple trains at the same time, the conflict detection of the operation diagram is realized and the results are intuitively displayed, and support is provided for subsequent operation diagram adjustments. Therefore, the embodiment of the present application effectively improves the effectiveness and reliability of the operation diagram conflict detection.
