Description

Technical Field

[0001] The present invention relates to the technical field of railway positioning, and in particular to a method and system for positioning a line of on-board detection equipment based on a train operation diagram. Background Art

[0002] The train relies on a series of technical means such as ground signal machines, ground transponders, speed sensors, and onboard databases to accurately locate the current position of the train. The current position of the train refers to the specific position of the railway line where the train is currently located, including: line name (or line number), line type, and kilometer mark. For example: Beijing-Guangzhou Line (line number 0001) - Downward - 100.130 kilometers, such a three-element expression can accurately locate a certain point on the railway.

[0003] At present, when using a vehicle-mounted line inspection instrument on a train to conduct dynamic inspection of the railway line, it is necessary to obtain the current line name or line number to determine the location of the defect, including inspection of the unevenness of the railway line, inspection of the comfort of train vehicles, video inspection of railway ground facilities, and video inspection of railway power supply facilities. However, due to the safety restrictions on train operation and railway data, the vehicle-mounted inspection equipment must be fixedly installed at a designated position on the locomotive. During the inspection, the equipment can obtain the train number and mileage data from the train monitoring system, but cannot obtain the key information of the current line name from the train monitoring system. It is impossible to obtain the line that the train is currently running, and it is impossible to accurately locate the specific location of the train on the railway line. When the inspection equipment generates inspection data, it is impossible to accurately determine the location of each inspection data.

[0004] If these detection devices cannot obtain accurate location information, then no matter what the detection data results are, they cannot be provided to the production link for use, because on-site maintenance personnel must know the three elements of "line name (or line number), line type, and line mileage" before they can carry out on-site maintenance tasks and accurately reach the site that needs maintenance. Therefore, how to quickly and accurately locate the position of the train is a particularly important task.

[0005] At present, the positioning methods used by various types of vehicle-mounted detection equipment include: (1) Using satellite positioning Since the signals output by the satellite can only parse out information such as longitude, latitude, speed, etc., and there is no commercially available electronic railway map with railway mileage, it is impossible to obtain railway mileage directly.

[0006] The current solution is to manually establish the correspondence between railway mileage and longitude and latitude before use, such as collecting a longitude and latitude coordinate along the railway line every 100 meters (or shorter distance), and then build an electronic map corresponding to railway mileage and longitude and latitude. When in use, the portable device obtains the current longitude and latitude through its own satellite module, and then converts the current line mileage through the self-built railway electronic map.

[0007] Disadvantages: The biggest problem is whether the equipment hardware has the satellite positioning function. For example, the vehicle-mounted line inspection instrument is installed inside the train control box of the locomotive, so the satellite positioning module cannot be installed and it does not have the satellite positioning function. Secondly, due to the influence of terrain, positioning is slow in mountainous areas and the error is large, especially in tunnels where satellite signals cannot be received. Due to weather conditions, when the cloud layer is thick, positioning fails or the deviation is large. Self-built electronic maps require enough basic points to ensure detection accuracy, which requires a lot of manpower and material resources.

[0008] When the railway line is changed or the mileage is adjusted, it needs to be collected again.

[0009] (2) Using mobile phone signal base station positioning By installing a mobile phone module in the detection equipment and using the network query command, the nearby base station number can be obtained. By building a correspondence between self-built base stations and railway mileage, a correspondence between a base station and mileage can be established, which can determine the approximate location of the current train with an accuracy of about 200-2000 meters.

[0010] Disadvantages: It can only work in areas with mobile phone signals. It cannot be used in special areas such as tunnels, remote mountainous areas, and Gobi deserts. Base station information is basic telecommunications data, and it is difficult to collect it manually to build a map. When the base station is replaced, the map data cannot be updated in time. The positioning accuracy is poor, especially along the railway, because the number of base stations is less than that of cities, and the positioning accuracy is about 500 meters.

DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1 Embodiment 1 of the present invention provides a method for locating the line of on-board detection equipment based on a train operation diagram. When the on-board detection equipment detects unevenness on the railway line during train operation, through this positioning method, the equipment can accurately know the specific mileage location of a certain section of unevenness on the railway, thereby providing an accurate geographical reference for subsequent maintenance work. The method for mileage positioning of on-board detection equipment based on a train operation diagram overcomes the problem that the on-board detection equipment cannot directly obtain the line number and thus cannot accurately locate by combining the train operation diagram, speed information and on-board detection equipment data. The method can generate accurate location information for the equipment without being affected by hardware (Beidou positioning cannot be installed) and the environment (such as tunnels, mountainous areas and other places where the mobile phone signal base station signal is weak), and is suitable for the positioning needs of various types of railway detection equipment.

[0025] like Figure 1 As shown, a method for locating a line of an on-board detection device based on a train operation diagram comprises: Step 110, the on-board detection equipment collects train operation data; In the embodiment of the present application, the train operation data includes but is not limited to basic data information obtained from the train operation timetable, line mileage details, line connection point information, and station and line relationship table of the railway ledger.

[0026] Train timetable: the arrival and departure times of trains at each station.

[0027] Line mileage details table: includes line number, line name, starting mileage, ending mileage, and line type (single line, up, down). The line type represents the direction of train operation. The up line can only run trains in the up direction, the down line can only run trains in the down direction, and the single line can run trains in both directions.

[0028] Line connection point information: mainly the intersection information of two lines, including the names of the two lines with the intersection point and the line type and mileage information of each line when they intersect. It means that line A intersects with line B at a certain mileage of a certain line type, which is used for cross-line operation of trains.

[0029] The relationship table between stations and lines: that is, which lines pass through the train station, the type of lines, mileage and other information.

[0030] Step 120: determine line running information according to the train running data, and generate a train running diagram according to the line running information, wherein the train running diagram includes a correspondence between line number, line type and mileage information; The route operation information, i.e., the operation diagram, is generated according to the train operation schedule. When generating the operation diagram, the route operation information between the current two stations is generated according to the current "departure station" and "next arrival station", and is traversed one by one according to the train operation schedule to generate the operation diagram of the entire train.

[0031] When generating the route information of the "departure station" and the "next arrival station", different operations are performed according to different situations, including: (1) Two stations are on the same line: This situation is the simplest, indicating that the trains are running on the same line. As long as the "departure time" to "arrival time" of the "departure station" and the "arrival station" is within the mileage range between the two stations, it means that the current train is running on the current line; so the operation diagram information can directly record the mileage information of the two stations on the line.

[0032] (2) There is an intersection between the lines where the two stations are located: The "departure station" and the "next arrival station" are not on the same line. It is necessary to check whether there is an intersection between the lines where the two stations are located. If there is, it means that the train needs to run from Line A to Line B via the intersection.

[0033] When generating the operation diagram, it is necessary to record the station mileage from the "departure station" to the "line intersection point where the departure station is located", and the station mileage from the "line intersection point where the arrival station is located" to the "arrival station".

[0034] (3) The lines where the two stations are located have no intersection, but the two lines intersect with a third line at the same time: The "departure station" and the "next arrival station" are not on the same line. It is necessary to check whether there is an intersection between the lines of the two stations. If there is no intersection, check the intersection line a of line A and the intersection line b of line B. If there is the same line C between a and b, it means that line A needs to run to line C first, and then run to line B via line C.

[0035] Therefore, based on the above-mentioned line operation conditions, when generating the operation diagram, it is necessary to record: ① the station mileage from the "departure station" to the "C line intersection point"; ② the mileage from the "intersection point of the line where the departure station is located and the C line" to the "intersection point of the line where the C line is located and the arrival station is located"; ③ the mileage from the "intersection point of the line where the C line is located and the arrival station is located" to the station mileage of the "arrival station".

[0036] (4) The lines where the two stations are located have no intersection and do not intersect with a third line at the same time: In addition, for the complex situation of "the lines where the two stations are located have no intersection and do not intersect with the third line at the same time", it is necessary to query the line bridge points. The so-called bridge points are the line running information between line A and line B. It is complex, or there is a lack of line, station and other information. The program cannot directly generate line running information. At this time, you can set up bridge points to correctly record the connection relationship between the lines where the two stations are located, that is, how line A is connected to line B. In this way, the line running information of the complex operation diagram can be generated.

[0037] For this complex situation, the line running information first needs to enter the starting line, mileage and ending line, mileage of the bridge point, and then generate it through the program. The algorithm uses a dynamic programming algorithm to check whether the generated line running information is correct. If it is correct, it will be directly entered into the database. When generating the train operation diagram, it can directly match the starting information and ending information of the bridge point to see if they are consistent.

[0038] When a dynamic programming algorithm is used to generate line running information, if the information generated by the program is incorrect line running information, or no line running information is generated, it is necessary to manually enter the train operation diagram and complete basic information.

[0039] Among them, common situations of incomplete information include: ① Incomplete line list: If the line information in the line list is missing, some key lines may be missed in the dynamic planning process, resulting in incomplete or wrong paths. Trains may pass through some unrecorded lines in actual operation, resulting in the generated path not being consistent with the actual situation. ② Missing line connection point information: Line connection point information is the key connection point between multiple lines. If these connection point data are missing or inaccurate, the train may not be able to switch from one line to another correctly. This will cause the program to be unable to find the correct path during the dynamic planning process, and may even cause the search to fall into an infinite loop or completely skip some reasonable paths. ③ Incomplete station and line relationship table: If the correspondence table between stations and lines is incomplete, especially when some stations are not associated with the correct lines, the system may mistakenly believe that the train cannot pass through these stations, thereby generating wrong routes. For example, a station is actually located at the intersection of multiple lines, but these relationships are not correctly reflected in the relationship table, and the train may be planned to pass through the wrong line. ④ Inaccurate mileage or station information: If the mileage of the station or the specific location data of the station is inaccurate, the train's path planning may be wrong. For example, the lack of mileage jump points can lead to large errors in path calculation, causing the train to be positioned at the wrong mileage segment.

[0040] After a detailed analysis of the above situation, the line operation diagram is obtained. For example, the line operation diagram between Chongqing North and Bishan stations is shown in Table 1 below: Table 1 Line operation diagram between two stations

[0041] Step 130: When locating a train, the onboard detection equipment collects train data in real time, extracts train number data, time and mileage data from the train data, and obtains the line number and corresponding line type by combining the train number data and time with the generated train operation diagram; Among them, the on-board detection equipment will be connected to the train monitoring system (such as TAX (train monitoring and recording device)\DMS system (train control operation monitoring system)) when it is started. When the on-board detection equipment is running, it can obtain the train operation data provided by the TAX\DMS system in real time, such as mileage data, train number data, etc. The line information can be obtained through the current time, mileage, and train number data combined with the generated train operation diagram.

[0042] like Figure 2 As shown, the line information is obtained by combining the collected train data with the generated train operation diagram, which specifically includes the following sub-steps: Step 210, extract the train number from the train data, and check whether the train number is valid. If it is valid, execute step 220, otherwise, the line number acquisition fails; When identifying a line, the first thing to do is to determine whether the train number is a valid train number to prevent errors in line number identification due to incorrect train information caused by communications, train depots, etc.

[0043] Step 220, obtaining and determining whether there is a train operation diagram, if so, executing step 230, otherwise obtaining the line number fails; When the train number is valid, it is necessary to check whether there is a train diagram for this train number. If not, the train number will be added to the train diagram and marked as ungenerated train diagram. The system will generate train numbers for which no train diagram has been generated at regular intervals. If the generation fails, the relevant personnel will be reminded to manually generate the train diagram information.

[0044] Step 230, extract the current time from the train data, and determine whether the current time is consistent with the train running time. If it is consistent, execute step 240, otherwise, the line number acquisition fails; After obtaining the operation diagram of the train, it is necessary to determine whether the current data time is within the operating time of the train. When the data time is not within the operating time range of the train, it means that the train has not officially run or the train has ended, and there is no need to obtain the line number.

[0045] Step 240, obtaining the train operation diagrams of the two stations where the current train is located according to the current time; When the data time is within the train running time range, it is necessary to determine between which two stations the current train is running based on the time, and then obtain the train operation diagram between the two stations, that is, the line running information.

[0046] Step 250: Determine the line number and the corresponding line type according to the obtained train operation diagram.

[0047] After obtaining the train operation diagram, the line number is determined according to different line shape information of the train operation diagram, such as Figure 3 As shown, it specifically includes the following sub-steps: Step 310, determine whether there is line information in the train operation diagram, if yes, execute step 320, otherwise, the line number acquisition fails; If the line running information is not obtained, it means that no valid line running data has been generated, and the line number cannot be obtained.

[0048] Step 320, determine how many lines exist in the train operation diagram, if there is one line, execute step 330, if there are multiple lines, execute step 340; Step 330: extract mileage information from the train data, and determine whether the mileage information is within the line mileage range of the train operation diagram. If yes, the line number is generated successfully, otherwise, the line number acquisition fails. Step 340, determining whether there is duplication in the line mileage ranges of the train operation diagrams of the multiple lines, if there is duplication, executing step 350, otherwise executing step 330; Step 350: Eliminate the train operation diagram corresponding to the line that has been passed according to the historical data, extract the mileage information from the train data, and determine whether the mileage information is within the line mileage range of the remaining train operation diagram. If so, the line number is generated successfully, otherwise the line number acquisition fails.

[0049] Specifically, if there is only one line running information obtained, it is necessary to judge based on the data mileage. When the data mileage is within the mileage range of the line running information, the line number of the current line running information can be obtained. If there are multiple line running information obtained, it means that the train needs to pass through each line in sequence to reach the next station. At this time, it is necessary to determine whether there are repeated mileage sections (whether the digital range is repeated) in the starting mileage and ending mileage of these lines. If there are no repetitions, it is directly determined one by one which line running information the current mileage meets. When the mileage section is repeated, it is necessary to determine whether the train has passed the line running information one by one based on the historical data of the current train (on the day), and eliminate the line running information that has passed, so as to determine the running position of the current train and obtain the correct line number of the current train when the mileage range is repeated.

[0050] Step 140: Determine the precise location of the current on-board detection equipment based on the line information, line type, and mileage data in the train data.

[0051] When the on-board detection equipment obtains the current line number based on the data time, train number, mileage and the train operation diagram, the precise location of the current on-board detection equipment can be obtained (three elements: line - line type - mileage), thereby achieving the purpose of locating the equipment.

[0052] Embodiment 2 like Figure 4 As shown, the second embodiment of the present invention provides a system for locating the line of on-board detection equipment based on the train operation diagram, including: a train monitoring system 41 (TAX or DMS system) and an on-board detection equipment 42; the on-board detection equipment 42 will be connected to the train monitoring system 41 when it is started, and the on-board detection equipment 42 can obtain the train operation data provided by the train monitoring system 41 in real time when it is running; the on-board detection equipment 42 specifically includes: The data collection module 421 is used to collect train operation data; A train operation diagram generating module 422, configured to determine line running information according to train operation data, and generate a train operation diagram according to the line running information; The on-board detection equipment positioning module 423 is used for real-time collection of train data by the on-board detection equipment when locating the train, and obtains the line number and the corresponding line type by combining the collected train data with the generated train operation diagram; and determines the precise position of the current on-board detection equipment based on the line information, line type and mileage data in the train data.
