Description

Technical Field

[0001] This invention relates to the field of station yard data storage and display technology, and in particular to a layer-based ladder diagram scheduling centralized system station yard storage and display method. Background Technology

[0002] Centralized Traffic Control (CTC) systems are widely used in train dispatching and command on my country's high-speed railway lines. It is a crucial system for dispatchers at the dispatch center and station staff to centrally control signaling equipment within their jurisdiction and to direct train operations. It is an important piece of operational equipment in railway dispatching and command, and a vital management facility for ensuring punctual and orderly train operation. Currently, the CTC system is widely used and is an essential signaling system for railway dispatching and command and centralized control in China. CTC system display terminals are installed in numerous locations, including dispatch centers, station operations rooms, electrical maintenance centers, dispatch center leadership and management positions, electrical department management positions, and other station query positions. Each display terminal is equipped with CTC station display software and data. Through this CTC software, users can view the status of station elements and train operation information. However, the following problems have been encountered in practical applications:

[0003] 1) The size of the stations on site varies, the display screens of the terminals are different, the number of stations to be monitored varies, the location of the stations being observed is different, and the focus of the stations being monitored is different. As a result, the 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 site graphics of the same station on different display terminals, and the workload of data upgrade and project replacement is large.

[0005] The following section introduces two commonly used solutions.

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

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

[0007] CTC designers create a "single-station display graphic description file" for the CTC system, hereinafter referred to as "station diagram" or "CTC diagram," based on the input files such as the actual station layout plan, interlocking interface file, and train control interface file provided by the railway design institute. Each component in the station yard, the logic alarm lights of the interlocking and train control specialties, and the status lights of the CTC specialties can all be abstracted into a "station yard object." For example, tracks, turnouts, turnouts, entry signals, exit signals, shunting signals, insulating joints, and platforms are actual station yard components, while buttons, train number windows, alarm lights, status lights, direction text, and kilometer marker text belong to logical station yard objects.

[0008] The designers of the CTC system first draw a site map of the CTC system based on the input files mentioned above. Following the actual site layout, the designers draw each type of equipment. The drawing of each type of equipment mainly involves the type of object, its specific location coordinates, and the relationships between objects.

[0009] When storing station layout diagrams, the system will store them as a binary data stream file according to the above specifications. The meaning of each data stream byte in the file will be executed according to the above protocol definition.

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

[0011] However, the drawback of Option 1 is that the CTC system provides display terminals for various professional positions, including: electrical management positions, electrical maintenance positions, front-line transportation positions, transportation management positions, front-line dispatching center positions, dispatching center management positions, and other professional review positions, etc. Each station map will include all station information related to the entire station's interlocking, train control, and CTC systems. Specifically:

[0012] 1) Different users have different actual needs, and their requirements regarding which station objects they want to monitor vary. Taking the dispatch center console as an example, the current main display terminal shows all stations in the jurisdiction, typically 10-30 stations. Displaying all of them scaled down to a certain size on four monitors is neither clear nor intuitive. Dispatchers prefer a single macroscopic route and station map under normal circumstances. However, station personnel operating and controlling their own stations want to see all objects within their station but do not want to see electrical alarm lights and status lights, considering them meaningless interference. Furthermore, depending on the observation location, different terminals may require different forward and reverse layouts of the station map. For example, depending on the terminal's location, the station map may need to be flipped. Figure 1 As shown.

[0013] 2) The project implementation involves a massive workload. When managing existing station data, a separate station map is created for each station and each type of terminal. Since these station maps differ for each type of terminal, during project deployment, several different station files need to be maintained for a single station. If the actual attributes of an object in the station need to be modified—for example, changing a signal from a high-mast to a low-mast—the station maps for all terminals must be modified and replaced one by one. Each station file corresponds to a specific type of terminal and cannot be mixed, making the process extremely cumbersome.

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

[0015] 4) The existing station map storage format cannot be dynamically expanded. For example, when the station is expanded to add a new type or marker, it is necessary to modify the software's binary data reading method. The old version of the software cannot support the new station map storage file.

[0016] 5) Existing display standards specify the size of signal controllers, but in actual applications, screen resolutions and display sizes vary, failing to meet actual needs. Users prefer to adapt the size of the display to different sizes.

[0017] Option 2: Use B / S (browser-server) technology to display the station data. Set up a "station information processing" backend server to centrally handle the station representation. All software and station map data are centrally stored on the backend server. The frontend browser only views the station display and does not deploy specific application data and software.

[0018] However, the drawback of Option 2 is that while the BS mode reduces the amount of data maintenance and modification required for the front-end terminals, the back-end server still needs to maintain and process all different station maps. Furthermore, it cannot meet the specific station display needs of transportation dispatching, electrical, and management positions. This mode also fails to solve the problem of maintaining station map data across multiple different types of terminals. Summary of the Invention

[0019] The purpose of this invention is to provide a layer-based ladder diagram scheduling centralized system station storage and display method, which redesigns the station data storage method, introduces layer storage and management methods, designs a layer storage and display method that adapts to multiple scenarios, and also includes a simplified ladder diagram station display method.

[0020] The objective of this invention is achieved through the following technical solution:

[0021] A layer-based ladder diagram-based centralized scheduling system for station storage and display includes:

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

[0023] For the display attribute information in the attribute category, each corresponding display method is treated as a layer, and each layer is stored separately. The layers cover all types of terminals that can display, including the simplified trapezoidal diagram layer of the station.

[0024] As can be seen from the technical solutions provided by the present invention above, 1) the station maps required by different terminal types and different scenarios are integrated, and the attribute information of station objects is stored in partitions. One station map can encompass station maps of all scenarios, greatly reducing the workload of engineering maintenance; 2) through partitioned storage and layer management, it can adapt to all display requirements of terminals in different positions; 3) in the new mode, it can dynamically switch between different layers, and realize multiple different display styles of one display terminal; 4) the simplified ladder diagram display mode is constructed, providing a macroscopic perspective for observing stations, greatly improving the display range and observation capability of dispatching and command.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0032] First, the following explanations are provided for the terms that may be used in this article:

[0033] The terms “including,” “comprising,” “containing,” “having,” or other similar semantic descriptions should be interpreted as non-exclusive inclusion. For example, “including a technical feature element (such as raw material, component, ingredient, carrier, dosage form, material, size, part, component, mechanism, device, step, process, method, reaction conditions, processing conditions, parameter, algorithm, signal, data, product or article of manufacture, etc.)” should be interpreted as including not only the expressly listed technical feature element, but also other technical feature elements that are not expressly listed and are well-known in the art.

[0034] The term "composed of" excludes any technical features not expressly listed. When used in a claim, it closes the claim to exclude all technical features other than those expressly listed, except for associated conventional impurities. If the term appears only in a clause of a claim, it limits the claim to the elements expressly listed in that clause; elements recited in other clauses are not excluded from the overall claim.

[0035] The following is a detailed description of a layer-based ladder diagram-based centralized scheduling system for station storage and display provided by the present invention. Contents not described in detail in the embodiments of the present invention are prior art known to those skilled in the art. Where specific conditions are not specified in the embodiments of the present invention, they shall be performed according to conventional conditions in the art or conditions recommended by the manufacturer.

[0036] The station storage and display method of a layer-based ladder diagram scheduling centralized system provided by this invention mainly includes three parts: attribute type division based on usage dimension, partitioned storage based on attribute type, and layer-based display scheme. Specifically: the storage information corresponding to station objects in the station diagram is divided into multiple attribute categories, and a separate storage partition is allocated for each attribute category; for the display attribute information in the attribute category, each corresponding display method is treated as a layer, and each layer is stored separately. The layers cover all types of terminals that can display, including the simplified ladder diagram layer of the station.

[0037] Preferably, the attribute categories include: fixed foundation attribute information, construction-related attribute information, and display attribute information; wherein, the fixed foundation attribute information is the descriptive 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 storing each attribute category in a separate storage partition, XML storage is used.

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

[0040] Preferably, the simplified trapezoidal diagram layer of the station includes: the station throat to the arrival and departure tracks and the station yard map of the block section outside the station, and the station yard objects displayed are the station yard objects of the simplified version of the station yard map.

[0041] Preferably, the simplified trapezoidal diagram layer of the station includes the display of virtual route triangles. The virtual route triangle for receiving routes is displayed on the receiving side of the track, and the virtual route triangle for departure routes is displayed at the reverse entry signal at the departure port.

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

[0043] To more clearly demonstrate the technical solution and its effects provided by the present invention, the method provided by the embodiments of the present invention will be described in detail below with reference to specific examples.

[0044] I. Attribute type classification based on usage dimension.

[0045] In this embodiment of the invention, the information to be stored is divided into three categories based on usage: fixed basic attribute information, construction-related attribute information, and display attribute information. Each category is then stored independently.

[0046] Fixed basic attribute information generally includes: the type of station object (e.g., signal, track, turnout, etc.), the number of the station object, the name of the station object, and other basic signal data of the station object (e.g., whether the signal is a high-mast signal or a low-mast signal; for track sections, attributes such as track length, whether there is a platform, and whether oversized vehicles can be connected; the relationship between various objects, such as the linkage between turnouts, the relationship between tracks and train windows, etc.). All of the above data are fixed attribute information of station objects.

[0047] Construction-related attribute information generally includes: information such as the data collection and wiring that needs to be set for the station object during the construction of the project. For example, if it is necessary to collect the status of a certain signal, the data collection board and data collection point information should be assigned to it.

[0048] The display attributes of station objects are the key information extracted, mainly including: the location coordinates of the station object, the display style of the station object, and the size and length of the station object. Additionally, the attribute of "whether the station object is hidden" is also emphasized. For partition information, the concept of layers is introduced during storage; each specific display method is treated as a layer.

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

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

[2018] Train Dispatch and Command System (TDCS) Data Communication Regulations" is abandoned, and the XML storage method is used instead. The advantage of storing in XML format is that new fields can be easily extended in the future, and it is still compatible with old versions of software. The current binary data stream file format cannot achieve dynamic expansion and old version compatibility.

[0051] The aforementioned three attribute types are partitioned and stored into three areas: basic information area (stores fixed basic attribute information), construction information area (stores construction-related attribute information), and layer information area (stores display attribute information), such as... Figure 2 As shown. This basic version of the site map can be called a basic hologram.

[0052] III. Layer-based display scheme.

[0053] In this embodiment of the invention, the concept of layers is introduced in the "layer information partitioning". The display attributes of objects are stored independently in each layer of the partition. Each layer has an ID, layer name, usage scenario description, etc. In each layer, the display attributes of the station objects are redefined, including coordinate position, graphic size and length, number of graphic endpoints, whether to hide or not display, etc., as shown in Table 1.

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

[0055]

[0056]

[0057] Each site map is configured with multiple layers to suit various scenarios. The following example uses a standard scenario with four automatically built-in layers, corresponding to the display requirements of four different scenarios:

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

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

[0060] (3) The central transportation map (X left S right) does not display some station objects of the electrical engineering specialty according to transportation needs;

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

[0062] Furthermore, to meet the needs of special terminals, new layers and station object display attribute information can be added and stored in a separate layer, such as... Figure 3 As shown.

[0063] In practical applications, the display terminal software can use a specific layer ID to display station objects by specifying or manually selecting it, while simultaneously reading information from other layers and dynamically switching between them.

[0064] Using the above method, the site map used by any terminal is the same. A single site map file can encompass the layer display of all types of terminals. During project implementation, each station only needs to maintain one file, and during project upgrades, there is no need to consider the type of terminal before directly replacing it. At the same time, new layer displays can be designed for any terminal to meet the needs of on-site users.

[0065] Considering that various types of terminals, such as the dispatcher's main display terminal, the duty manager's display terminal, the station signalman's field terminal, and the passenger terminal, usually do not care about the details of the internal objects of the station, but focus on the train movement, that is, the external section of the station and the status of the station's arrival and departure tracks, a simplified trapezoidal diagram of the station is designed and constructed and stored in a dedicated layer.

[0066] The simplified trapezoidal station layout (a simplified trapezoidal diagram layer for stations) focuses only on displaying the station throat to arrival / departure tracks and external block sections. The displayed station objects include: arrival / departure sections, entry signals, arrival / departure tracks and exit signals on both sides of the tracks, train number windows, and advance train number windows. For example, the simplified trapezoidal diagram of a large station would look like this: Figure 4 As shown; at the same time, other station objects are hidden in the simplified trapezoidal diagram layer of the station.

[0067] Preferably, to better display the status of each station section and turnout along the route, a virtual route triangle is added during the display process. This involves logically ANDing the status of station objects along the train route to display the end of the route. Specifically: the virtual route triangle for receiving routes is displayed on the receiving side of the track, and the virtual route triangle for departing routes is displayed at the reverse entry signal at the departure port.

[0068] by Figure 5 Taking the train route scenario shown as an example: 1) X-7G receiving route: When the X-7G route is successfully routed, the X entry signal opens the permission signal. At this time, all station objects along the track from the entry signal to the track are locked. At this time, on the receiving side of the track, the newly added virtual route triangle is displayed as a green triangle. Figure 5 A red triangle is used to mark (using a filled horizontal line) to indicate that the current X-7G route is locked; when a train is entering the station, if any station object along the route from the entry signal to the track is occupied by a train, it is displayed as a red triangle. Figure 5 A triangle filled with vertical lines is used to mark the position (indicated by the train being on the X-7G route); this status is no longer displayed when the train has fully entered the track. 2) 5G-SN departure route: When the X5-SN route is successfully arranged, the X5 enable signal is activated, and a virtual route triangle is added at SN and displayed in green. Figure 5 (Using a triangle symbol filled with horizontal lines to mark it), when a train is running over the X5 to SN station area, the virtual route triangle is displayed in red. Figure 5 The virtual route triangle is marked using a filled vertical line. Once the train has completely cleared the route, the virtual route triangle will no longer be displayed.

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

[0070] 1) Integrate the station maps required for different terminal types and scenarios, and store the attribute information of station objects in partitions. One station map can encompass station maps for all scenarios, which greatly reduces the workload of engineering maintenance.

[0071] 2) By using partitioned storage and layer management, it can adapt to all display needs of terminals in different positions;

[0072] 3) In the new mode, different layers can be dynamically switched, enabling a single display terminal to display multiple different styles;

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

Based on this understanding, the technical solutions of the above embodiments can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (such as a CD-ROM, USB flash drive, external hard drive, etc.), including several instructions to cause a computer device (such as a personal computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.
