Description

Technical Field

[0001] The present invention relates to the technical field of station yard data storage and display, and in particular to a layer-based ladder diagram type centralized dispatching system station yard storage and display method. Background Art

[0002] The Centralized Traffic Control (CTC) system is currently widely used in the train dispatching and command of my country's high-speed railway lines. It is an important system for the train dispatchers of the dispatching center and the train personnel of the station to centrally control the signal equipment within the jurisdiction and dispatch and command the train operation. It is an important driving equipment in railway dispatching and command, and it is also an important management facility to ensure the punctual and orderly operation of trains. At present, the CTC system is widely used and is an essential signal system for China's railway dispatching and command and centralized dispatching control. The CTC system has set up station display terminals in a variety of locations such as the dispatching center, station operation room, electrical maintenance center, leadership and management positions of the dispatching center, management positions of the electrical department, and other station section query positions. Each display terminal is deployed with CTC station display software and data. Through the CTC software, users can view the status of station elements and train operation conditions. In actual application, the following problems are faced:

[0003] 1) The sizes of on-site stations vary, the display screens of terminals vary, the number of double-view stations varies, the locations of observation stations vary, and the focus of monitoring stations varies. On-site users are very dissatisfied with the existing display specifications of the current CTC system;

[0004] 2) During project implementation, it is very complicated to uniformly modify, manage and maintain the station graphics of the same station on different display terminals, and the workload of data upgrade and project replacement is large.

[0005] The following introduces two commonly used solutions.

[0006] Solution 1: When the centralized dispatching CTC system displays and stores management at the station yard, it stores the data of station yard objects in accordance with the requirements of "QCR444

[2018] Train Dispatching and Command System (TDCS) Data Communication Procedure" and displays the status of station yard objects in accordance with the requirements of the CTC station yard technical specification "Dispatching Centralized Operation Display Specifications China Railway General Engineering and Electric Power (2018) No. 69".

[0007] CTC designers make the "Single Station Yard Display Graphic Description File" of the CTC system according to each actual station yard plan, interlocking interface file, train control interface file and other input files provided by the Railway Design Institute, hereinafter referred to as "Station Yard Map" or "CTC Yard Map". Each component of the station yard, the logical warning lights of the interlocking and train control professions, the status lights of the CTC profession, etc., can be abstracted as a "station yard object", such as tracks, no switches, switches, entry signals, exit signals, shunting signals, insulation joints, and platforms are actual station yard components, while buttons, train number windows, warning lights, status lights, direction texts, kilometer mark texts, etc. are logical station yard objects.

[0008] The designers of the CTC system first draw a station map of the CTC system based on the above input files. According to the actual station layout, the designers draw each object device. When drawing each object, the main contents involved include the type of object, specific location coordinates, and the relationship between objects.

[0009] When storing the station yard diagram, the system will store it as a binary data stream file in accordance with the above-mentioned specifications. The meaning of each data stream byte in the file is implemented according to the above-mentioned protocol definition.

[0010] Each front-end display terminal is equipped with a set of CTC display software and station map data, which reads the current status of the display station and receives data to update the object.

[0011] However, the flaw of Solution 1 is that the CTC system provides display terminals for various professional positions, and the application scenarios include: electrical management positions, electrical maintenance positions, front-line transportation positions, transportation management positions, front-line dispatching center positions, dispatching center management positions, other professional review positions, etc. Each station map will include all station information of the entire station interlocking, train control, and CTC system. Specifically:

[0012] 1) Different users have different actual needs, and have different requirements on which station objects they expect to monitor. Taking the dispatch center dispatch desk as an example, the current dispatch desk's total display terminal displays all stations in the jurisdiction, usually 10-30 stations, which are reduced to a certain size ratio on 4 displays to display all of them. This is neither clear nor very intuitive. The dispatcher hopes that only a macro line station map is needed under normal circumstances; and the transportation personnel at the station hope to display all objects of the station when operating and controlling the station, but do not want to see the electrical-related alarm lights and status lights on the station, as they think they are meaningless interference. In addition, depending on the observation position, different terminals expect different front and back layouts of the station map. For example, depending on the setting position of the terminal, the station map may need to be flipped. Such as Figure 1 shown.

[0013] 2) The project implementation task is huge. When storing and managing existing station data, a separate station map is made for each station and each type of terminal. The station maps of various terminals are different. Therefore, when the project is deployed and implemented, several different station files need to be maintained for one station. Once the actual attributes of an object in the station need to be modified, such as changing a signal from a high column to a short column, the station maps of all terminals need to be modified and replaced one by one. Each station file corresponds to a certain type of terminal and cannot be mixed, which is very cumbersome.

[0014] 3) The existing display method and logic cannot realize the equipment status display of different professions and levels such as transportation and electrical services.

[0015] 4) The storage format of the existing station diagram cannot be dynamically expanded. For example, when a new type or mark is added to the station, the software's way of reading binary data needs to be modified. The old version of the software cannot support the new station diagram storage file.

[0016] 5) The existing display specifications have provisions for the size of traffic lights, but in actual applications, the screen resolution and display size vary, which does not meet actual needs. Users prefer to be able to adapt to larger or smaller sizes.

[0017] Solution 2: Use BS technology (browser-backend server) to realize the display of the station field. Set up a backend server for "station field information processing" to uniformly process the station field representation. All software and station field map data are centrally stored in the backend server. The front-end browser only views the station field display and does not deploy specific application data and software.

[0018] However, the drawback of Solution 2 is that, in BS mode, the amount of data maintenance and modification of the front-end terminal is reduced in general, but the back-end server still needs to maintain and process all different station maps, and the special station display requirements for transportation dispatch, electrical services, and management positions cannot be met. This mode also cannot solve the problem of difficult maintenance of station map data under multiple different types of terminals. Summary of the invention

[0019] The purpose of the present invention is to provide a layer-based ladder diagram-type dispatching centralized system station field storage and display method, redesign the station field data storage method, introduce the layer storage and management method, design a layer storage and display method that adapts to multiple scenes, and also include a simplified ladder diagram-type station field display method.

[0020] The objective of the present invention is achieved through the following technical solutions:

[0021] A layer-based ladder diagram centralized dispatching system station yard storage and display method, comprising:

[0022] The storage information corresponding to the station objects in the station map is divided into multiple attribute categories, and each attribute category is divided into a separate storage partition for storage;

[0023] For the display attribute information in the attribute category, each corresponding display mode is regarded as a layer, and each layer is stored separately. The layers cover the layers that can be displayed by all types of terminals, including the simplified ladder diagram layer of the station.

[0024] It can be seen from the technical solutions provided by the present invention that 1) the station diagrams required for different terminal types and different scenarios are integrated, and the attribute information of the station objects is stored in partitions. One station diagram can include the station diagrams of all scenarios, which greatly reduces the workload of engineering maintenance; 2) through partition storage and layer management, it can adapt to all display requirements of terminals in different positions; 3) in the new mode, it is possible to dynamically switch between different layers, and a variety of display styles can be realized for one display terminal; 4) a simplified ladder diagram display mode is constructed, which provides a macro perspective for observing the station, greatly improving the display range and observation capabilities of dispatching and commanding.

For example, including certain technical feature elements (such as raw materials, components, ingredients, carriers, dosage forms, materials, dimensions, parts, components, mechanisms, devices, steps, procedures, methods, reaction conditions, processing conditions, parameters, algorithms, signals, data, products or products, etc.) should be interpreted as including not only certain technical feature elements explicitly listed, but also other technical feature elements known in the art that are not explicitly listed.

[0034] The term "consisting of..." means excluding any technical feature elements not explicitly listed. If this term is used in a claim, it will make the claim closed, so that it does not contain technical feature elements other than the technical feature elements explicitly listed, except for the conventional impurities related to them.

[0035] The following is a detailed description of a layer-based ladder diagram scheduling centralized system station field storage and display method provided by the present invention. The contents not described in detail in the embodiments of the present invention belong to the prior art known to professional and technical personnel in the field. If no specific conditions are specified in the embodiments of the present invention, they shall be carried out according to the conventional conditions in the field or the conditions recommended by the manufacturer.

[0036] The embodiment of the present invention provides a layer-based ladder diagram centralized dispatching system station yard storage and display method, which mainly includes: attribute type division based on usage dimension, partition storage based on attribute type, and layer-based display scheme. Specifically: the storage information corresponding to the station yard object in the station yard diagram is divided into multiple attribute categories, and a separate storage partition is divided for each attribute category for storage; for the display attribute information in the attribute category, each corresponding display mode is regarded as a layer, and each layer is stored separately, and the layers cover the layers that can be displayed by all types of terminals, including the simplified ladder diagram layer of the station.

[0037] Preferably, the attribute categories include: fixed basic attribute information, construction-related attribute information and display attribute information; wherein, the fixed basic attribute information is the description information of the station object's own attributes; the construction-related attribute information is the relevant attribute information of the station object during engineering construction; and the display attribute information includes the relevant attribute information of the station object when it is displayed.

[0038] Preferably, when each attribute category is divided into a separate storage partition for storage, XML storage is adopted.

[0039] Preferably, each layer has an ID, a layer name and a usage scenario description, and in each layer, the display attribute information of the station field objects is redefined.

[0040] Preferably, the simplified ladder diagram layer of the station includes: a station yard diagram from the station throat to the arrival and departure tracks and the block partition outside the station, and the displayed station yard objects are station yard objects of the simplified version of the station yard diagram.

[0041] Preferably, the simplified ladder diagram layer of the station includes the display of a virtual approach triangle, the virtual approach triangle of the receiving route is displayed on the receiving side of the track, and the virtual approach triangle of the departure route is displayed at the reverse entry signal of the departure port.

[0042] Preferably, the layers cover the layers that can be displayed by all types of terminals, including: dynamically switching the currently displayed layers according to the current type of terminal and the usage scenario.

[0043] 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.

[0044] 1. Classification of attribute types based on usage dimensions.

[0045] In the embodiment of the present invention, the information to be stored is divided into three categories based on the usage dimension: fixed basic attribute information, construction-related attribute information, and display attribute information. With this partitioning, each piece of information is stored independently.

[0046] Fixed basic attribute information generally includes: the type of station object (such as signal, track, switch, etc.), the number of the station object, the name of the station object, other basic signal data of the station object (for example, whether the signal is a high-column signal or a low-column signal; for the track section, including the length of the track, whether there is a platform, whether it can accommodate overloaded vehicles and other attributes; the relationship between each object, such as the linkage relationship between switches, the relationship between tracks and train number windows, etc.). The above data are all fixed attribute information of station objects.

[0047] Construction-related attribute information generally includes: information such as the collection and wiring data that needs to be set up when the station object is under construction. For example, if the status of a certain signal needs to be collected, a collection board and collection point information need to be allocated to it.

[0048] The display attribute information of the station object is the key information to be stripped, including: the location coordinates of the station object, the display style of the station object, the size of the station object, etc., and the attribute of "whether the station object is hidden" is added. When storing the partition information, the concept of layer is introduced, and each special display mode is regarded as a layer.

[0049] 2. Partition storage based on attribute type.

[0050] In an embodiment of the present invention, when storing the station diagram, the storage method of the binary data stream in the "QCR444

[2018] Train Dispatching and Command System (TDCS) Data Communication Procedure" is abandoned and the XML storage method is used instead. The advantage of storing in XML format is that new fields can be easily expanded later and the old version of the software can still be compatible. The current binary data stream format file format cannot be dynamically expanded and compatible with the old version.

[0051] The above three attribute types are partitioned and stored into three areas: basic information partition (storing fixed basic attribute information), construction information partition (storing construction-related attribute information), and layer information partition (storing display attribute information). Figure 2 This basic version of the site map can be called a basic hologram.

[0052] 3. Layer-based display solution.

[0053] In the embodiment of the present invention, in the "layer information partition", the layer concept is introduced, and the display attributes of the object are placed in each layer in the partition for independent storage. Each layer has an ID, a layer name, a description of the usage scenario, etc. In each layer, the display attributes of the station object and other information are redefined, including coordinate position, graphic size, number of graphic endpoints, whether to hide or not display, etc., as shown in Table 1.

[0054] Table 1: Display properties of station objects in the layer

[0055]

[0056]

[0057] Each station map is configured with multiple layers to suit various scenarios. The following takes the common scenario as an example, where 4 layers are automatically built-in. The 4 built-in layers correspond to the display requirements in 4 scenarios, including:

[0058] (1) The positive image corresponding to the basic hologram (X left S right) is used for the detailed control map of a single station;

[0059] (2) The flipped image (S right X left) corresponding to the basic hologram is used for the detailed control image of a single station;

[0060] (3) The main diagram used for central transportation (X on the left, S on the right) does not show some of the station objects of the electrical engineering department according to transportation requirements;

[0061] (4) The flip diagram (S right X left) used for central transportation does not display some station objects of the electrical engineering department according to transportation requirements.

[0062] In addition, new layers and station object display attribute information can be added to meet the needs of special terminals and stored in independent layers, such as Figure 3 shown.

[0063] In actual applications, a certain layer ID can be specified and manually selected in the display terminal software to display the station object, and other layer information can be read and switched dynamically.

[0064] In this way, the station map used by any terminal is the same. A station map file can include the layer display of all types of terminals. During project implementation, each station only needs to maintain one file, and there is no need to consider the type of terminal when upgrading the project. At the same time, a new layer display can be designed for any terminal to meet the needs of on-site users.

[0065] Taking into account the dispatcher's general display terminal, the duty manager's display terminal, the station signalman's field terminal, the passenger terminal and other types of terminals, usually do not care about the internal object details of the station, but focus on the movement of trains, that is, the station's off-station section and the status of the station to the departure track. For this purpose, a simplified ladder diagram station display method is designed and constructed, and stored in a dedicated layer.

[0066] The simplified ladder diagram of the station only focuses on the display of the station throat to the arrival and departure tracks and the block partition outside the station. The displayed station objects include: the receiving and departure interval, the station entrance signal, the arrival and departure tracks and the departure signals on both sides of the tracks, the train window, the train window, the train window, etc. The simplified version of the station diagram, for example, a large station, the simplified ladder diagram is as follows Figure 4 As shown; at the same time, other station objects are hidden in the simplified ladder diagram layer of the station.

[0067] Preferably, in order to better display the status of each station section and turnout of the route, the display of the virtual route triangle is added during the display processing, and the status of the station objects along the train route is logically "AND" merged to display the end of the route. Specifically: the virtual route triangle of the train receiving route is displayed on the receiving side of the track, and the virtual route triangle of the departure route is displayed at the reverse entry signal of the departure port.

[0068] by Figure 5 Take the train route scenario shown in the figure as an example: 1) X-7G train approach. When the X-7G approach is successfully arranged, the X station signal opens the permission signal. At this time, the station objects from the station signal to the track are all locked. At this time, on the train receiving side of the track, the newly added virtual route triangle is displayed as a green triangle ( Figure 5 The triangle symbol filled with horizontal lines is used to mark the current X-7G route, which is used to indicate that the current X-7G route is locked; when a train is approaching the station, if any of the station objects from the station signal to the track is occupied by the train, it will be displayed as a red triangle ( Figure 5 2) 5G-SN departure route. When the X5-SN route is successfully arranged, X5 opens the permission signal. At this time, a virtual route triangle is added at SN and displayed in green ( Figure 5 When the train runs from X5 to SN station object, the virtual route triangle is displayed in red ( Figure 5 When the train has completely cleared the route, the virtual route triangle will no longer be displayed.

[0069] The solution provided by the embodiment of the present invention mainly achieves the following beneficial effects:

[0070] 1) Integrate the station diagrams required for different terminal types and different scenarios, and store the attribute information of station objects in partitions. One station diagram can include station diagrams for all scenarios, greatly reducing the workload of engineering maintenance;

[0071] 2) Through partition storage and layer management, it can adapt to all display requirements of terminals in different positions;

[0072] 3) In the new mode, you can dynamically switch between different layers, and realize multiple different display styles on one display terminal;

[0073] 4) Constructing a simplified ladder diagram display mode provides a macroscopic perspective for observing the station, greatly improving the display range and observation capabilities of dispatching and commanding.

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.
