Description

Technical Field

[0001] The present invention relates to the field of track technology, and in particular to a method and system for symbol management of continuous multi-interval events on a running diagram. Background Art

[0002] In the centralized dispatching (CTC) system, the operation diagram is the center and brain of traffic dispatching and commanding. It not only gathers various driving plans, but also needs to mark various temporary events so that dispatchers can grasp the overall transportation production information. Among them, the interval identification symbols generated by construction maintenance or natural disasters are used very frequently.

[0003] According to the existing centralized dispatching operation display specifications and transport dispatching rules, based on different related transport events, interval symbols mainly include three categories: interval blockade, interval slow movement and construction and maintenance skylights (hereinafter referred to as skylights). According to the frequency of use and the degree of impact, the following mainly uses the common interval slow movement symbols in disaster weather such as wind, rain and snow as an example to illustrate. According to the display specification requirements, the interval slow movement symbol needs to be drawn in red between two adjacent horizontal lines representing the station on the operation diagram (hereinafter referred to as the station name line), and it must carry specific information about the speed limit event. Its marking effect is as follows: Figure 1 As shown, considering the requirements of the accompanying drawings, Figure 1 Symbol colors are omitted.

[0004] In existing applications, section construction symbols are drawn and marked one by one according to the single section formed by adjacent station name lines on the operation diagram. Taking the large-scale section speed limit scenario under rain and snow disaster weather, which is common in actual operation, as an example, the symbol setting process of the existing technical solution is as follows: Figure 2 As shown. When the dispatcher receives the relevant speed limit information, he must first split it into multiple station intervals on the operation diagram according to the speed limit kilometer range (for example, station A-station B-station C-station D). After that, the dispatcher needs to repeatedly draw three interval slow-moving symbols between the station name lines AB, BC, and CD on the diagram for identification. These three interval slow-moving symbols are not related to each other, so the speed limit details related to the symbols need to be edited independently. If deletion or modification is required, it should be done independently for each symbol.

[0005] The above existing technical solutions mainly have the following technical problems:

[0006] (1) For a large-scale interval event, the dispatcher needs to manually create interval symbols one by one on the operation diagram, which requires the personnel to have a high level of accuracy in remembering the relationship between the station names, lines and intervals on the diagram and the connection directions. For hub dispatch desks and hub stations with many connection directions, the symbol settings are complex, and personnel need to draw them and check the specific information one by one.

[0007] (2) For a large-scale interval event, the attribute information of multiple related interval symbols cannot be automatically synchronized, and the dispatcher needs to manually edit and set them one by one. In this way, on the one hand, the correspondence between the interval symbols on the map and the events is unclear, and on the other hand, it greatly increases the workload of the personnel. When a large-scale interval speed limit or construction occurs, it takes up a lot of dispatcher energy.

[0008] (3) For a large-scale interval event, there is a lack of unified management for the addition and deletion of multiple interval symbols, resulting in a large number of repetitive operations in the work of dispatchers. Summary of the invention

[0009] The purpose of the present invention is to provide a method and system for symbol management of continuous multi-interval events on an operation diagram, so as to solve various technical problems existing in the prior art solutions.

[0010] The objective of the present invention is achieved through the following technical solutions:

[0011] A symbol management method for continuous multi-interval events on a running diagram, comprising:

[0012] Based on the data of the jurisdiction lines, a topological model of the associated sections of each station and different driving directions is constructed;

[0013] For each continuous multi-interval event, combined with the influence range elements of the continuous multi-interval event on the jurisdiction line, the associated interval is searched in the associated interval topology model;

[0014] According to the searched associated intervals, corresponding interval symbols are created on the operation diagram, and the interval symbols belonging to the same continuous multi-interval event are divided into the same group and assigned a group ID;

[0015] Dynamic management and maintenance of interval symbol attributes based on group ID.

[0016] A symbol management system for continuous multi-interval events on a running diagram, comprising:

[0017] The associated section topology model building unit is used to build the associated section topology model of each station and different driving directions of the line according to the jurisdiction line data;

[0018] An associated interval intelligent search unit, for searching for associated intervals in the associated interval topology model for each continuous multi-interval event in combination with an influence range element of the continuous multi-interval event on the jurisdiction line;

[0019] The associated interval symbol construction and grouping unit is used to create corresponding interval symbols on the operation diagram according to the searched associated intervals, divide the interval symbols belonging to the same continuous multi-interval event into the same group, and assign a group ID;

[0020] The attribute synchronization unit of multiple interval symbols is used to dynamically manage and maintain the attributes of interval symbols based on group IDs.

[0021] It can be seen from the technical solution provided by the present invention that: (1) from the creation of interval symbols, a group relationship is established according to the event, and the mapping of events and interval symbols is realized, thereby realizing the unified management of internal data maintenance and external addition and deletion operations; (2) according to the impact range elements of the interval event and the actual interconnection topology structure of the jurisdiction line, the associated intervals are automatically screened to reduce errors and omissions in the symbol creation process; (3) when the associated interval symbols of the same group are created and the attribute information is modified, the attribute synchronization of each symbol in the group is automatically completed, which greatly reduces the workload of the dispatcher.

[0038] Embodiment 1

[0039] The embodiment of the present invention provides a method for symbol management of continuous multi-interval events on a running diagram, such as Figure 3 As shown, it mainly includes the following steps:

[0040] Step 1: Construct the associated interval topology model.

[0041] In the embodiment of the present invention, a topological model of associated sections of each station on the line and in different driving directions is constructed based on the jurisdiction line data.

[0042] Step 2: Intelligent search of associated intervals.

[0043] In the embodiment of the present invention, for each continuous multi-interval event, the associated interval is searched out in the associated interval topology model in combination with the influence range element of the continuous multi-interval event on the jurisdiction line.

[0044] Step 3: Create and group interval symbols.

[0045] In the embodiment of the present invention, corresponding interval symbols are created on the operation diagram according to the searched associated intervals, and the interval symbols belonging to the same continuous multi-interval event are divided into the same group and assigned a group ID.

[0046] Step 4: The interval symbol attributes are automatically synchronized.

[0047] In an embodiment of the present invention, dynamic management and maintenance of interval symbol attributes are performed based on the group ID. Specifically: when the attribute of a certain interval symbol changes, it is determined whether the attribute of the probability of occurrence belongs to a set category (i.e., a key information category); if so, a group ID validity check is performed. After the check, other interval symbols with the same group ID are selected, and the modified attribute information is synchronized to the selected other interval symbols.

[0048] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the method provided by the embodiment of the present invention is described in detail with reference to specific embodiments below.

[0049] 1. Overall overview of the plan.

[0050] The embodiment of the present invention provides a symbol management method for continuous multi-interval events on the operation diagram, which effectively solves many problems existing in the existing technical solutions. First, the concept of interval symbol grouping management is proposed. Based on a continuous multi-interval event, multiple interval symbols in the association group are associated, and the corresponding relationship is clear, in line with business reality and easy for personnel to understand. Secondly, based on the concept of interval symbol grouping, a unified management method for creation and deletion is provided, which can complete the automatic screening of associated intervals, one-key creation and deletion of corresponding symbols, and real-time display of associated intervals according to information such as the impact of interval events on driving directions. By establishing a group mapping relationship between interval events and multi-interval symbols at the business logic level, the attribute information of the associated interval symbols in the same group can be automatically synchronized, and the unified management method of the associated interval symbols in the group greatly simplifies the symbol setting and modification operations of the dispatcher, and avoids unexpected situations such as related interval symbols affecting the driving direction due to negligence or lack of experience, thereby improving the efficiency and accuracy of related work.

[0051] In the embodiment of the present invention, a mapping relationship is constructed between events and interval symbols on the operation diagram, and management and maintenance of each group of associated symbols are performed through group ID. In practical applications, the management mode of independent maintenance of each symbol in the prior art solution (existing solution) is broken away. For editing events such as symbol creation, modification, and deletion, the mapping model can be used to directly match objects and automatically synchronize them in the internal business of the software, and the mapping model can also be used to present an intuitive and easy-to-understand symbol management interface to dispatchers externally. A comparison of the interval symbol management logic in the existing solution and the solution of the present invention (improved solution) is shown in Figure 1. Figure 4 As shown, the symbol management logic of the existing solution is above the dotted line, and the symbol management logic of the solution of the present invention is below the dotted line.

[0052] 2. Introduction to the details of the plan.

[0053] The main process of the symbol management method for continuous multi-interval events on the operation diagram provided by the embodiment of the present invention is as follows: Figure 5 As shown, based on the existing jurisdiction line data, the topological model of the associated intervals of each station and different driving directions of the line is constructed. When searching for associated intervals and creating symbols based on interval events, the topological model is used as the basis to realize intelligent search and symbol construction of associated intervals according to the driving direction and initial interval affected by the event. It can be mainly divided into the following four parts: 1. Construction of the associated interval topological model (line topological model); 2. Intelligent search of associated intervals; 3. Automatic construction of associated interval symbols; 4. Automatic synchronization of attributes of multi-interval symbols; each part is introduced in detail below.

[0054] 1. Construction of the associated interval topology model.

[0055] In the embodiment of the present invention, a graph theory structure algorithm is used to abstract each station and line into an independent node, which is represented as a node set V = {v1, v2, ..., v n}; where each v represents a node, the subscript is the node number, and n is the number of nodes. The connection intervals between each station and line station are described by the directed connection arcs of the nodes according to the connection direction, and the directed connection arc set is represented as A = {(v i ,v j )v i ,v j ∈V}; where (v i ,v j ) is the node v i Points to node v j Directed connection arcs. The direction mark is introduced as the connection arc weight, and the connection arc weight is combined to express W = {(w i,j )(v i ,v j )∈A}; where (w i,j ) represents a directed connection arc (v i ,v j ). Finally, the associated interval topology model D = (V, A, W) is obtained. After that, the adjacency matrix M and the direction weight matrix N are used for data maintenance. The model example is as follows Figure 6 As shown, the following scheme logic description is based on this scenario and the corresponding theoretical description. Figure 6 In the example shown, the circle represents the station, the arrow represents the connected section, and the direction of the arrow also indicates the connection direction.

[0056] 2. Intelligent search of associated intervals.

[0057] by Figure 7 Take the continuous multi-interval event shown in the figure as an example. For the continuous interval event from station 1 to station 7, multiple interval symbols on the operation diagram need to be set. In the actual line, there are multiple connecting paths between two stations according to the running direction and the passing stations (in this example, there are 3 connecting paths with different driving directions, such as path R1 = {(v1, v2), (v2, v3), (v3, v6), (v6, v7)}).

[0058] First, extract the influence range elements of the interval event on the jurisdiction line: the starting node s, the ending node e and the set of affected driving directions W′, which are all known input information in the actual dispatching and command work; among them, the starting node and the ending node are used as the termination condition check items in the process of searching for associated intervals, and the set of affected driving directions is used as the constraint condition in the process of searching for associated intervals. For actual transportation organization work, there may be multiple driving directions affected by interval events, such as the upward direction, the downward direction, the upward / downward direction of a branch line, etc., which are usually represented by different direction values, corresponding to w i ′,w i ′ belongs to the set W′, which is used to identify all the influencing directions of the interval events between the starting and ending points.

[0059] In the embodiment of the present invention, the event associated initial interval (v s1 ,v s2 ) as the benchmark, search (match) the nodes and intervals of the associated stations / lines in the associated interval topology model, such as Figure 8 shown.

[0060] (1) Construct a set of labeled associated node arcs I, a set of labeled non-associated node arcs J, and a set of unlabeled node arcs K. In the initial state, the set of labeled associated node arcs I only contains the given event association initial interval (v s1 ,v s2 ) in two nodes v s1 With v s2 , the marked non-associated node arc set J is an empty set, and the remaining nodes are in the unmarked node arc set K.

[0061] (2) Adjacent node search: Starting from the nodes in the given event association initial interval, adjacent node matching is performed from the unlabeled node arc set K to obtain the corresponding directed connection arcs. For the matched directed connection arcs, there must be a node that is a labeled associated node, and there is an actual connection relationship between the two nodes. Because the search for adjacent nodes requires finding the adjacent points of the labeled associated nodes according to the connectivity of the graph, the newly obtained connection arc must be found from the already associated points, and there must be a marked associated point.

[0062] In the embodiment of the present invention, the nodes in the given event association initial interval are used as the initial nodes to search for adjacent nodes; from a theoretical point of view, v s1 With v s2 can be used as the initial node, so when searching for adjacent nodes, you can start from v s1 With v s2 Start by searching in the direction of impact. However, in practice, the initial interval is usually required to be the first impact interval of the event, so v s1According to the direction of influence, usually only v can be found s2 , and directly with v s2 This has the same effect as starting the search as the initial node.

[0063] (3) Direction matching: The interval event affects the driving direction W′ as a constraint condition. If the direction weight of the matched directed connection arc is not satisfied, the directed connection arc (node ​​arc) is invalid and is included in the set J as a marked non-associated node arc; if the direction of the matched directed connection arc is affected by the interval event, it is included in the set I as a marked associated node arc.

[0064] (4) Determine whether the first termination condition (starting node and ending node check) is met: If the matched directed connection arc has matched the starting node or the ending node in the current search direction, the search for the directed connection arc in the current search direction is terminated, and it is determined whether there are other directions to be searched. If there are other directions to be searched, the process proceeds to the adjacent node search step, i.e., the aforementioned step (2). If there are no other directions to be searched, it indicates that the associated arc does not exist and the search is terminated. If the matched directed connection arc has not matched the starting node and the ending node in the current search direction, it is determined whether the second termination condition is met.

[0065] (5) Determine whether the second termination condition (the existence check of the associated arc, i.e., check whether there is an associated arc) is satisfied. Checking whether there is an associated arc means checking whether the latest adjacent node and other adjacent nodes that have not been marked form a directed connection arc: if there is no associated arc in the current search direction and node range in the current unmarked node arc set K, the search is terminated; otherwise, proceed to the adjacent node search step, i.e., the aforementioned step (2); wherein the latest associated node refers to the latest adjacent node obtained in this iterative search.

[0066] After the search is terminated, each directed connection arc in the marked associated node arc set I is an associated interval that may be affected by the event.

[0067] 3. Associated interval symbols are automatically constructed.

[0068] For multiple intervals associated with the searched event, the present invention will automatically create interval symbols between the corresponding adjacent station name lines on the operation diagram, and the key attribute information of the interval event of each symbol will remain consistent. For multiple interval symbols associated with the same event, they will be automatically divided into the same group and assigned a group ID to facilitate unified data management within the program, and a list of associated intervals will be provided for the dispatcher to view and edit.

[0069] 4. The properties of multi-interval symbols are automatically synchronized.

[0070] Based on the above scheme, after completing the creation of interval symbols, the following Figure 4The mapping relationship between events and multiple interval symbols is shown in the figure. Therefore, dynamic data management and maintenance can be performed based on the group ID. Therefore, when the dispatcher edits the properties of a certain interval symbol in the group, the program can automatically determine whether it is a key information element of the interval event to which it belongs, and decide whether to automatically synchronize it to other related symbols in the group. The information synchronization process of related symbols in the group is as follows: Fig. 9 shown. Fig. 9 The interval symbol grouping mapping model shown in refers to establishing a group relationship from the beginning of symbol creation based on a continuous multi-interval event. By building a mapping relationship between events and multiple symbols (see the introduction in the previous article for related implementation solutions), unified management of internal data maintenance and external addition and deletion operations can be achieved based on this model.

[0071] The above solution provided by the embodiment of the present invention mainly achieves the following beneficial effects:

[0072] (1) Based on the actual transportation production, a mapping relationship is established between events such as section construction / disasters and multiple section symbols on the operation diagram, which is clear and easy to understand.

[0073] (2) Based on the association model between events and interval symbols on the operation diagram (interval symbol grouping mapping model), an intuitive and easy-to-maintain data structure is provided for both the internal data management of the application software and the external personnel operation interface, solving the problems of repeated operations by dispatchers and easy data errors in existing solutions.

[0074] (3) An intelligent search scheme for associated intervals based on the scope of event impact is proposed, and the interval validity check and screening functions are intelligently implemented according to the static data of the line, which reduces the workload of dispatchers and significantly improves the efficiency and accuracy of interval symbol management on the operation diagram.

[0075] (4) Based on the group management data structure of interval symbols, processes such as automatic creation of associated interval symbols and synchronization of key attributes are proposed, which significantly reduces the workload of dispatchers in handling interval transportation organization events and improves the efficiency and accuracy of interval symbol management on the operation diagram.

[0076] In general, the interval symbol management method of the operation diagram terminal has been optimized by the present invention. Whether it is the data maintenance inside the software or the management operation of the front-end interface, a clear and understandable association with the interval event has been established, which is convenient for on-site data maintenance personnel and dispatchers. At the same time, it also effectively improves the management efficiency and accuracy of the interval symbols on the operation diagram, which is conducive to the stable, safe and efficient operation of the system, and greatly reduces the workload of dispatchers, which is of practical significance.

[0077] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above embodiments can be implemented by software, or by means of software plus necessary general hardware platforms. Based on such understanding, the technical solutions of the above embodiments can be embodied in the form of software products, which can be stored in a non-volatile storage medium (which can be a CD-ROM, a USB flash drive, a mobile hard disk, etc.), including several instructions for enabling a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in the various embodiments of the present invention.

[0078] Embodiment 2

[0079] The embodiment of the present invention also provides a symbol management system for continuous multi-interval events on a running diagram, which is mainly used to implement the method provided in the above embodiment, such as Fig.10 As shown, it mainly includes:

[0082] The associated interval symbol construction and grouping unit is used to create corresponding interval symbols on the operation diagram according to the searched associated intervals, divide the interval symbols belonging to the same continuous multi-interval event into the same group, and assign a group ID;

[0083] The attribute synchronization unit of multiple interval symbols is used to dynamically manage and maintain the attributes of interval symbols based on group IDs.

[0084] In the embodiment of the present invention, the construction of the topological model of the associated sections of each station and different driving directions of the line includes:

[0085] Each station and line station on the line is abstracted into an independent node, represented as a node set V = {v1,v2,...,v n}; where each v represents a node, the subscript is the node number, and n is the number of nodes;

[0086] The connecting sections between each station and line station are described by the directed connection arcs of the nodes according to the connecting direction, and the directed connection arc set is represented as A = {(v i ,v j )v i ,v j ∈V}; where (v i ,vj ) is the node v i Points to node v j Directed connecting arcs of;

[0087] The direction mark is introduced as the connection arc weight, and the connection arc weight is combined and expressed as W = {(w i,j )(v i ,v j )∈A}; where (w i,j ) represents a directed connection arc (v i ,v j )’s weight;

[0088] Finally, the associated interval topology model D = (V, A, W) is obtained.

[0089] In an embodiment of the present invention, the impact range elements of the continuous multi-interval event on the jurisdiction route include: a starting node, an ending node and a set of affected driving directions; wherein the starting node and the ending node serve as termination condition inspection items in the process of searching for associated intervals, and the set of affected driving directions serves as a constraint condition in the process of searching for associated intervals.

[0090] In the embodiment of the present invention, searching for the associated interval in the associated interval topology model includes:

[0091] Construct a marked associated node arc set I, a marked non-associated node arc set J and an unmarked node arc set K; in the initial state, the marked associated node arc set I only contains two nodes in the given event association initial interval, the marked non-associated node arc set J is an empty set, and the remaining nodes are all in the unmarked node arc set K;

[0092] Adjacent node search: associate the nodes in the initial interval with the given event, match the adjacent nodes from the unlabeled node arc set K, and obtain the corresponding directed connection arcs;

[0093] Direction matching: The interval event affects the driving direction W′ as a constraint condition. If the direction weight of the matched directed connection arc is not satisfied, the directed connection arc is invalid and is included in the set J as a marked non-associated node arc; if the direction of the matched directed connection arc is affected by the interval event, it is included in the set I as a marked associated node arc;

[0094] Determine whether the first termination condition is met: if the matched directed connection arc has matched the start node or the end node in the current search direction, the search for the directed connection arc in the current search direction is terminated, and it is determined whether there are other directions to be searched. If there are other directions to be searched, the adjacent node search step is entered. If there are no other directions to be searched, it means that the associated arc does not exist and the search is terminated; if the matched directed connection arc has not matched the start node and the end node in the current search direction, it is determined whether the second termination condition is met;

[0095] Determine whether the second termination condition is met, that is, check whether there is an associated arc. Checking whether there is an associated arc means checking whether the latest adjacent node and other unmarked adjacent nodes form a directed connection arc: if there is no associated arc in the current search direction and node range in the current unmarked node arc set K, the search is terminated; otherwise, go to the adjacent node search step;

[0096] After the search is terminated, each directed connection arc in the marked associated node arc set I is an associated interval.

[0098] When the attribute of a certain interval symbol changes, determine whether the attribute of the probability of occurrence belongs to the set category;

[0099] If so, a validity check of the group ID is performed. After the check is passed, other interval symbols with the same group ID are selected, and the modified attribute information is synchronized to the selected other interval symbols.
