Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway station yard display, and in particular to a railway station yard line power-on / off dynamic visualization method and device. BACKGROUND

[0002] As an important part of high-speed railway, the overhead contact line system is essential for daily power-off maintenance operation, so it is particularly important to timely and conveniently grasp the power-on / off state of the overhead contact line system. At present, the overhead contact line system power-on / off operation adopts a standardized process to realize approval management in the form of "electronic + paper". The traditional overhead contact line system power-on / off visualization method mainly uses static sketches or two-dimensional CAD diagrams to display the overhead contact line system distribution, switch equipment and line power-off / supply information. However, for the complex overhead contact line system line equipment scene of the railway station yard (including multiple tracks, line intersection, and complicated equipment), and the needs of the development of intelligent operation and maintenance of the overhead contact line system, the traditional method has the following shortcomings: 1) The traditional method cannot comprehensively and dynamically display the power-on / off state of all overhead contact line systems in the railway station yard: the related information on the static sketches and two-dimensional CAD diagrams cannot be updated in time as the work progresses, and the management personnel need to repeatedly communicate with the field personnel by telephone to confirm, and the CAD diagrams mainly show the partial power-on / off line situation of the station yard. In the event of an emergency, the management personnel cannot grasp the overall information of the overhead contact line system of the station yard, so they cannot give timely treatment suggestions.

[0003] 2) The traditional method cannot display the spatial distribution trend of the overhead contact line system of the railway station yard in three dimensions: the two-dimensional diagram can only display the horizontal line distribution trend of the overhead contact line system, and cannot reflect the complex spatial distribution trend and spatial topological relationship of the overhead contact line system, which is likely to cause misjudgment, especially misjudging the up-down staggered intersection of the line as a horizontal connection point.

[0004] In addition, the existing railway overhead contact line system equipment production and operation and maintenance management system and various intelligent operation and maintenance systems all use B / S architecture to provide services on the Web. At present, such operation and maintenance systems mainly use BIM models to display the overhead contact line system data. This method needs to render and load the overall model of the railway overhead contact line system, which has the disadvantages of occupying many resources, slow loading, and high requirements for hardware devices. Therefore, this method does not support lightweight operation on the Web, which is not conducive to the integration and display of existing business systems. SUMMARY

[0029] In order to dynamically update and visually display the power transmission and cut-off state of all overhead contact line routes in a railway yard, and at the same time visualize the complex spatial distribution trend and spatial topological relationship of the overhead contact line routes, an embodiment of the present application proposes a railway yard line power transmission and cut-off dynamic visualization method and device, which can support lightweight operation of a Web terminal, thereby being conducive to integration and display of an existing business system and realizing synchronous update and rapid preview of a multi-terminal power transmission and cut-off state.

[0030] Figure 1 A flowchart of a railway yard line power transmission and cut-off dynamic visualization method in an embodiment of the present application is shown in FIG. 1. Figure 1 As shown in FIG. 1, the method comprises the following steps: In step S110, a line path is generated based on spatial vector data of a railway yard line to construct a line three-dimensional model, wherein the spatial vector data comprises a plurality of line region information in the railway yard.

[0031] In some embodiments, the step S110 of generating a line path based on the spatial vector data of the railway yard line to construct a line three-dimensional model comprises the following steps: rendering and drawing the line path based on the spatial vector data of the railway yard line to construct the line three-dimensional model by using the PolylineGlowMaterialProperty in the Cesium engine.

[0032] The spatial vector data of the railway yard line can be KML format data generated by relevant personnel referring to CAD design drawings of all catenary lines of the railway yard and key equipment such as switching devices and sectional insulators arranged in the switching devices, and using a two-dimensional and three-dimensional integrated desktop GIS software platform. Then, the KML data is loaded by using the Cesium engine, and the line path is rendered and drawn based on the KML data by using the PolylineGlowMaterialProperty in the Cesium engine, and then an initialized railway yard line three-dimensional model is constructed. The line three-dimensional model can visually and stereoscopically display the complex spatial distribution trend and spatial topological relationship of the overall line of the railway yard, and can truly reflect the relative position and distance of the key equipment such as the conductor and the insulator, the positioning device and the like arranged in the space. The switching device includes types such as disconnectors and circuit breakers. The line region information includes spatial coordinate information and ID information of the line region and the like.

[0033] In some embodiments, the line region includes a line section between two switching devices and the two switching devices, or the line region includes a line section between a switching device and a sectional insulator, the switching device and the sectional insulator.

[0034] The line region mainly includes two types of line regions, one is a line region divided by two switching devices, including two switching devices and a line section between the two switching devices, and the other is a line region divided by a switching device and a sectional insulator, including a switching device and a sectional insulator and a line section between the switching device and the sectional insulator. Therefore, the spatial coordinate information of the line region can include line section spatial coordinate information and two switching device spatial coordinate information, or include line section spatial coordinate information, switching device spatial coordinate information and sectional insulator spatial coordinate information. The ID information of the line region can include the ID information of the line section and the two switching devices, or include the ID information of the line section, the switching device and the sectional insulator.

[0035] The step S120 of dynamically acquiring updated power-on and power-off plan data, the power-on and power-off plan data including a target line region of planned power-on and power-off and a power-on and power-off approval state.

[0036] Before each maintenance of the overhead contact system in a railway station yard, different line power-on / off plans are formulated according to different maintenance tasks, so that the power-on / off plans are updated. Therefore, in order to enable the parties involved in the maintenance work of the overhead contact system in the railway station yard to quickly and intuitively master the overall latest power-on / off situation and state of the lines in the station yard, the updated power-on / off plan data needs to be dynamically acquired, so that the latest overhead contact system line power-on / off situation is dynamically updated and visualized. Specifically, a real-time bidirectional communication service can be established by using the WebSocket protocol, the WebSocket service is used to listen to the overhead contact system line power-on / off plan state change event in real time, when the power-on / off state in the power-on / off plan changes, the updated power-on / off plan data is acquired through an API interface request, so that the updated power-on / off plan data is dynamically acquired. The dynamically acquired data can be stored in the browser cache. One or more target line areas for which power is planned to be turned on or off are one or more specified line areas matched with the maintenance task.

[0037] In some embodiments, the power-on / off approval state includes, in sequence according to the approval process, an approved state, a registered state, a work order issued state, a power-off state, a power-off confirmed state, a signed report state, a signed report eliminated state, a signed report confirmed elimination state, a power-on state, a power-on confirmed state, a to-be-eliminated record confirmation state, and an eliminated record state.

[0038] In step S130, a target line area power-on / off configuration scheme is obtained based on the target line area and a preset power-on / off configuration scheme, and a line switch state and a line power supply state of the target line area are determined based on the power-on / off approval state, the preset power-on / off configuration scheme including power-on / off configuration schemes of multiple line areas in the railway station yard.

[0039] The preset power-on / off configuration scheme in this step can be a standardized (typical) overhead contact system line power-on / off configuration scheme obtained by relevant personnel analyzing the overhead contact system lines and switch devices of all tracks and loop lines in the railway station yard, i.e., a set of states in which all line area configurations of all scenarios in the railway station yard are powered off or powered on and ID information of all line areas, and the scheme is dataized and pre-configured and stored in a database, supporting local caching by a user end. Specifically, the preset power-on / off configuration scheme includes states in which switch devices in the multiple line areas of all scenarios in the railway station yard are configured to be on or off and states in which line sections are configured to be powered off or powered on, and also includes spatial coordinate information and ID information of the multiple line areas. Therefore, the target line area power-on / off configuration scheme includes states in which switch devices in the target line area are configured to be on or off and states in which line sections are configured to be powered off or powered on, and also includes spatial coordinate information and ID information of the target line area. The ID information of the line area can be information such as the name or number of the line area.

[0040] In some embodiments, in step S130, based on the power transmission and cut-off approval state, the line switch state and line power supply state of the target line region are determined, including the following steps: When the power transmission and cut-off approval state is empty or has been transmitted, it is determined that the line switch state of the target line region is open and the line power supply state is already supplied with power; When the power transmission and cut-off approval state is already approved, has been confirmed to transmit power, is waiting for cancellation confirmation, or has been cancelled, it is determined that the line switch state of the target line region is kept in the current open state and the line power supply state is continuously supplied with power; When the power transmission and cut-off approval state is already registered, it is determined that the line switch state of the target line region is open and the line power supply state is about to be cut off; When the power transmission and cut-off approval state is a work ticket has been issued, it is determined that the line switch state of the target line region is kept in the current open state and the line power supply state is kept in the current state of about to be cut off; When the power transmission and cut-off approval state is already cut off, it is determined that the line switch state of the target line region is closed and the line power supply state is not supplied with power; When the power transmission and cut-off approval state is already confirmed to be cut off, has been signed, has been eliminated, or has been confirmed to be released, it is determined that the line switch state of the target line region is kept in the current closed state and the line power supply state is continuously not supplied with power.

[0041] According to the above scheme, the line switch state includes two types of open and closed, and the line power supply state includes three types of already supplied with power or transmitted, not supplied with power or cut off, and about to be cut off.

[0042] In step S140, based on the target line region information in the power transmission and cut-off configuration scheme of the target line region, the target line region is located on the line three-dimensional model through information matching, and the power transmission and cut-off state of the located target line region is visualized based on the line switch state and the line power supply state.

[0043] The target line area information includes spatial coordinate information and ID information of the target line area. The spatial coordinate information of the target line area can include spatial coordinate information of the target line section and the target switching device thereof, or spatial coordinate information of the target line section, the target switching device thereof and the target sectional insulator. The ID information of the target line area can include ID information of the target line section and the target switching device thereof, or ID information of the target line section, the target switching device thereof and the target sectional insulator. The ID information of the switching device and the sectional insulator can be the name or number of the switching device and the sectional insulator. In this step, one or more target line areas (target line section and target switching device) to be visualized are first located in the initialized line three-dimensional model through spatial coordinates or ID information, and then the energization state of the target line area located in the line three-dimensional model is updated according to the target line switching and power supply state data obtained in step S130, so as to realize dynamic visualization of the energization state of one or more specified line areas. In addition, the timestamp can be updated synchronously when the state is updated, and synchronous update of the energization state of multiple terminals can also be supported.

[0044] In some embodiments, in step S140, the energization state of the located target line area is visualized based on the line switching state and the line power supply state, including the following steps: The line glow material property of the located target line area is modified based on the line switching state and the line power supply state, so as to visualize the energization state of the located target line area.

[0045] Specifically, the PolylineGlowMaterialProperty line glow material property of the target switching device and the target line section located in the line three-dimensional model can be modified by the Cesium engine, that is, the switching state of the target switching device and the power supply state of the target line section are modified, so as to update and visualize the energization state of the target line area located in the line three-dimensional model. The energization state of the target line area includes energization, de-energization and imminent de-energization. When the energization state of the target line area is energization, the state visualization can be displayed as red (as shown in Figure 2 and Figure 3 When the energization state of the target line area is de-energization, the state visualization can be displayed as green (as shown in Figure 2 and Figure 3 When the energization state of the target line area is imminent de-energization, the state visualization can be displayed as yellow (as shown in Figure 2 Of course, the above different states can also be displayed in other different colors.

[0046] In some embodiments, the power transmission and cut-off plan data further comprises the name, number and safety control measures of the unit applying for power transmission and cut-off; the number, name of the applicant, approval status and approval opinion of the power transmission and cut-off plan; the operation content, expected power cut-off time and expected power transmission time of the power transmission and cut-off plan; the name, number and contact number of the site supervisor; and the name and number of the plan compilation unit.

[0047] Correspondingly, before the step of matching recognition, the method further comprises the following steps: preprocessing the updated power transmission and cut-off plan data, the preprocessing comprising filtering out the key field data of the target line area of the planned power transmission and cut-off and the approval status, expected power cut-off time and expected power transmission time of the power transmission and cut-off in the updated power transmission and cut-off plan data, and converting the key field data of the expected power cut-off time and expected power transmission time into structured data for reference by relevant personnel.

[0048] Specifically, the key field data of the expected power cut-off time and expected power transmission time that are filtered out are converted in format to convert the data format into structured data in a minute-level date format, such as "yyyy / mm / dd hh:mm", where yyyy represents the year, mm represents the month, dd represents the day, hh represents the hour and mm represents the minute. The dynamically obtained data can be stored in the browser cache after preprocessing.

[0049] In summary, the railway station yard line power transmission and cut-off dynamic visualization method provided by the embodiments of the present application can display the spatial topological relationship and line spatial distribution trend of all overhead contact line systems and key equipment in the railway station yard in a lightweight three-dimensional scene on the Web (which can be realized by the Cesium engine tool), and deeply link with dynamically updated business data, can dynamically adjust the visualization state of the relevant overhead contact line system power transmission and cut-off according to the approval process state of the power transmission and cut-off plan, and generate a railway station yard line power supply situation visualization diagram, as shown in Figure 2 and Figure 3 The parties involved in the overhead contact line maintenance operation of the railway station yard can quickly preview the visualization diagram through the browser of the multi-terminal and quickly master the spatial distribution, switch equipment state, and power transmission and cut-off range, state and time of a specified line and the surrounding line equipment in the station yard.
