[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] To make the objectives, technical solutions and advantages of the present invention more clear, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] In a first aspect, an embodiment of the present invention provides a human-computer interaction method.

[0039] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the human-computer interaction method of the railway port digital freight yard system of the present invention. Figure 1 As shown, the human-computer interaction method includes:

[0040] Step S10, obtaining data to be displayed;

[0041] In some specific embodiments, step S10 includes:

[0042] Step S101, performing communication authentication with the railway port digital freight yard system;

[0043] In this embodiment, the railway port digital freight yard system is also the railway port digital freight yard dispatching and control integrated system, which will be used below. In the process of human-computer interaction, when obtaining the data to be displayed from each subsystem, it is necessary to first allow the display interface to communicate and authenticate with the railway port digital freight yard dispatching and control integrated system. Figure 2 , Figure 2 This is a schematic diagram of the communication authentication process of the present invention. Figure 2 As shown, the display interface (client) establishes a TCP / IP connection with the railway port digital freight yard dispatching and control integrated system (server). The display interface (client) sends an authentication request message containing information such as the user name and password. The railway port digital freight yard dispatching and control integrated system (server) performs communication authentication. If the communication protocol and data format requirements established internally are met, the communication authentication is determined to be successful. A message indicating that the authentication is successful and accepting the request is sent to the display interface. The display interface (client) then sends a data subscription message or other query message to the railway port digital freight yard dispatching and control integrated system (server).

[0044] The message attribute definitions for data subscription and unsubscription are shown in Table 1.

[0045] Table 1

[0046]

[0047] The sub-node definitions of the strings node in the data subscription message are shown in Table 2.

[0048] Table 2

[0049]

[0050] On the other hand, if the communication authentication fails, the integrated system for dispatching and controlling digital freight yards at railway ports (server) sends a connection rejection message to the display interface (client) and stops sending any data. This completes the process of establishing a connection between the display interface (client) and the integrated system for dispatching and controlling digital freight yards at railway ports (server).

[0051] Step S102: If the communication authentication result is passed, the data to be displayed of each subsystem is obtained by connecting to the ports of each subsystem of the railway port digital freight yard system, wherein the format of the data to be displayed is a preset format during the transmission process.

[0052] In this embodiment, refer to Figure 3 , Figure 3 This is a diagram showing the interaction of information inside and outside the interface. Figure 3 As shown, the display interface needs to access the program / data update server to read static data information about the lines and equipment. When the display interface is running, it also maintains a network connection with the integrated dispatching and control system for the railway port digital freight yard. The display interface sends the user's operation instructions and data subscription messages to the integrated dispatching and control system for the railway port digital freight yard through this connection. The integrated dispatching and control system for the railway port digital freight yard sends the monitoring data and fault analysis results of each data integration subsystem to the display interface. The display interface's user interface mainly includes: output devices and input devices. The output device is a large-screen display system used to display the graphical interface; the input devices include a common mouse and keyboard.

[0053] The display interface and the railway port digital freight yard dispatching and control integrated system transmit the data to be displayed of each subsystem through the TCP / IP protocol. The format of the data to be displayed sent and received by each subsystem is shown in Table 3.

[0054] Table 3

[0055]

[0056] The basic unit of communication between the display interface and the integrated railway port digital freight yard dispatching and control system is the message, which is carried as text data in XML format. The root node of the message is named "message" and has several attributes to indicate the message type and ID. The rest of the message content is stored in the root node's child nodes or in nodes below it.

[0057] The attribute definition of the root node of the message is shown in Table 4.

[0058] Table 4

[0059]

[0060] The content of the message is stored in the child nodes of the root node or in lower-level nodes. The definition of the child nodes is shown in Table 5.

[0061] Table 5

[0062]

[0063] Among them, the operating environment of the display interface is mainly the Windows operating system. After comprehensively measuring technical indicators such as operating efficiency, interface effects and compatibility, the development of the display interface adopts the development method based on Windows.NET C# language combined with WPF structural framework.

[0064] WPF (Windows Presentation Foundation), a component of the Microsoft .NET Framework development platform, is a presentation layer development framework based on XML, the .NET Framework, and vector graphics technologies. To separate the application's interface and backend logic, WPF uses the XML-based XAML markup language for interface development and C# for backend logic code, providing significant flexibility in implementing interface applications.

[0065] Reference Figure 4 , Figure 4 Schematic diagram of the rendering process of WPF drawing of the present invention. Figure 4 As shown, WPF acts as a bridge between the application and the graphics card screen frame buffer, encapsulating the complex process of calling the DirectX API of the graphics hardware without relying on the operating system's drawing interface, reducing development difficulty while ensuring the application's drawing efficiency. Figure 4In Windows, the operating system is used. When part or all of the displayed content in the window display area becomes invalid and the screen must be updated, the program will be notified by the WM_PAINT message and restored. The visualization object is to visualize the railway line on the human-computer interface, and WPF is the development of the interface.

[0066] Based on the above characteristics, the display interface of the railway port digital freight yard system is developed using C# and WPF.

[0067] Step S20, displaying the acquired data in an interface through a sub-window;

[0068] The interface display includes a global view interface display, a freight yard line view interface display, a freight yard station view interface display, and an equipment view interface display; in some specific embodiments, step S20 includes:

[0069] Display the global view interface based on the actual map data of the railway line range obtained from the railway port digital freight yard system;

[0070] Display the freight yard line view interface for the railway line data of the railway port digital freight yard system;

[0071] Display the freight yard station view interface based on the railway port digital freight yard system station information data;

[0072] For various types of data in the railway port digital freight yard system, an equipment view interface is displayed.

[0073] In this embodiment, the amount of monitoring data and comprehensive analysis data that need to be displayed in the display interface is very large. These data are sent from different rule sets in the railway port digital freight yard dispatching and control integration system and need to be displayed in different display interfaces. In addition, the logical hierarchy of the data is also different. For example: the PIO status data in the level crossing automatic control system maintenance machine belongs to the equipment-level monitoring data, which needs to be displayed in the equipment-level display interface of the railway port digital freight yard dispatching and control integration system, while the transponder health status evaluation data in the fault monitoring and analysis results of each subsystem of the railway port digital freight yard system belongs to the line-level analysis data, which needs to be displayed in the line-level display interface. How to effectively organize the display interface of these data is a key issue that needs to be solved in the display interface.

[0074] Therefore, a main window is set up within the display interface, from which all display interfaces can be centrally managed. Several subwindows, called "views," are designed within the main window interface to display data received from the integrated digital freight yard scheduling and control system. The subwindows are subordinate to the main window, and all subwindows are managed through the main window. Specifically, a "Startup Management" panel is set up on the main window to launch each view.

[0075] Each view can be divided into the following categories according to the logical level and content of the displayed data:

[0076] (1) Global view:

[0077] Based on the actual map data of the railway line range of the railway port digital freight yard system, a global view interface is displayed to show the working status of all lines, the working status of equipment in each freight yard station, the equipment connection status, the alarm information of the freight yard station, etc. Figure 5 As shown in the figure, the global view of the freight yard of the railway port digital freight yard system includes a freight yard line map and an equipment status and alarm summary panel.

[0078] (2) Freight yard line view:

[0079] For the railway line data of the railway port digital freight yard system, a line view interface is displayed to show the status of the railway port digital freight yard system freight line trackside equipment and the working status / connection status of the level crossing automatic control system. Figure 6 As shown, the freight yard route view includes: a freight yard route map panel, a freight yard route comprehensive analysis and early warning display panel, and a freight yard route-level comprehensive analysis and early warning query panel.

[0080] (3) Freight yard station view:

[0081] The digital freight yard system of the railway port provides a visual interface display for the station information data, showing the working status and network connection status of various trackside equipment in the freight yard station. In addition to displaying the working status of the equipment, the freight yard station view can also uniformly summarize and display the alarm information of each freight yard trackside equipment. Figure 7 As shown, the freight yard station view includes: a freight yard station display panel and a station equipment status and alarm summary panel. The freight yard station display panel includes: a freight yard station equipment working status and connection status summary panel, a freight yard station equipment alarm display panel and a freight yard station equipment alarm query panel.

[0082] (4) Device view:

[0083] The device view interface displays various types of data of the digital freight yard dispatching and control integrated system equipment. In the device view sub-window, the equipment is classified according to level crossing automatic control, electronic red card automatic protection, automatic gate for pick-up and delivery vehicles, and magnetic steel, etc. Users can go to the corresponding equipment maintenance display interface through the device view. Figure 8 As shown, the freight yard equipment view includes: a trackside equipment summary display panel, an automatic gate display panel for vehicle pickup and delivery, a level crossing automatic control summary display panel, and an electronic red card safety protection display panel. Among them, the freight yard route diagram display panel, equipment operating status display panel, equipment connection status display panel, equipment alarm display panel, and equipment alarm query panel are all equipment information display panels.

[0084] Step S30, encapsulating the graphic display control to obtain a user control;

[0085] Step S40: obtaining a static graphic corresponding to the data to be displayed through the interface of the user control, and displaying it on a corresponding interface;

[0086] The display interface and the interface of the user control are linked via the ID of the railway port digital freight yard system, and the static graphics include: points, curves and / or charts.

[0087] In this embodiment, during the development of the display interface, the main interface framework and graphic display controls were independently developed. To enhance the aesthetics of the interface, graphic display controls were used to control the display status of the data displayed in the subwindows, such as bar charts, line charts, and pie charts. These graphic display controls primarily include DevExpress for developing interface themes and the TeeChart control library specifically for icon development.

[0088] There are three types of data: instantaneous state, historical state, and statistical information, each with its own display method. List and table displays can be implemented using the system controls provided by WPF. However, for displays such as freight yard and railway station diagrams, line diagrams, equipment connection diagrams, line charts, pie charts, and bar charts, you need to develop your own user controls or purchase control libraries from third-party companies.

[0089] In terms of the selection of graphic display controls, the popular tools on the market include: DevExpress VCL Subscription, TeeChart for.NET, and ChartDirector. Their features are as follows:

[0090] DevExpress VCL Subscription: This is a suite of user interface products that includes the complete source code for all VCL and ASP.NET controls, along with related products. Controls include data entry, charting, data analysis, navigation, layout, grids, scheduling, styling, printing, and workflow.

[0091] TeeChart for.NET: is a powerful chart control that provides an efficient, intuitive and time-saving programming interface.

[0092] ChartDirector: It is a web chart control that is easy to use, fast, powerful, and highly interactive.

[0093] The above graphical display controls are compared in a table based on function, performance, and price. The control comparison table is shown in Table 6 below.

[0094] Table 6

[0095]

[0096] As shown in Table 6, Teechart for.NET is the most cost-effective graphics display control.

[0097] Furthermore, the drawing display control is repackaged into a user control. By loading the user control and calling its interface, the static graphics corresponding to the data to be displayed in each subsystem are obtained and displayed on the corresponding interface. The relationship between the display interface, user control and graphic display control is as follows: Figure 9 As shown. The user control provides a rich interface that can be set according to the data to be displayed. The interface functions implemented by the user control mainly include setting the chart name, chart horizontal axis name, chart vertical axis name, chart midpoint color and shape, explanatory text, chart curve data, chart curve color, chart bar chart and pie chart content and value.

[0098] The display interface is designed to display graphics such as station diagrams, equipment connection diagrams, and network topology diagrams. The display interface includes a graphic data parsing and display module, which can directly parse and statically display graphics stored in XML format. In order to change the state of the graphics after receiving the monitoring data sent by the digital freight yard scheduling and control integration system, the display interface controls the state of the equipment graphics in the diagram through the interface reserved by the graphic data parsing and display module (called: graphic control interface component), and changes the shape, color and text of the graphics. The advantages of adopting this solution are: for line changes or applications in different application scenarios, only the corresponding graphic files need to be replaced, and there is no need to recompile the display interface source program, which simplifies system updates and deployment operations; this solution can change the display appearance of the device without affecting the business logic of the device.

[0099] The device primitives on various graphics are uniformly drawn by the graphics display control. The drawn graphics can be roughly divided into two types based on their uses:

[0100] (1) An image of a freight yard railway line model, including graphics of numerous trackside devices, such as line diagrams and station yard diagrams. This type of diagram can display a wide range of information, including the status of various control devices, graphics showing the working status of each device, and the communication relationships between each device and other devices.

[0101] (2) Freight yard station equipment connection diagram and equipment status diagram. This diagram mainly includes trackside equipment, and the different colors of the lines between the equipment represent the communication status between the equipment.

[0102] The graphic display control outputs XML format graphic files (i.e., drawn static graphics) through human-machine operation by engineering personnel. Static graphics include: points, curves and / or charts. The display interface calls the "Graphic Reading and Control Interface Component", which is the interface of the user control, to read the XML format graphic files drawn by the graphic display control component, statically display the graphics and dynamically control the status of the device graphics. The specific collaborative relationship between the display interface and the graphic display control is as follows: Figure 10 shown.

[0103] Specifically, the graphics display control configures the device ID of the device primitive when drawing graphics. The display interface uses this device ID to call services provided by the "Graphics Reading and Control Interface Component" to dynamically control the state of the device primitive. The advantage of this approach is that it decouples the graphics control implementation details from the display interface. As long as the interface remains unchanged, changes to the implementation details of the "Graphics Control Component" will not affect the display interface program. The interface shields the display interface from the complexity of the underlying graphics control implementation.

[0104] The services provided by the Graphics Reading and Control Interface Component that are driven by the device ID are:

[0105] (1) Set the status of the equipment: set the derailer switch of the electronic red card safety protection subsystem to the status of positioning, reverse position and fault, set the color of the positioning and reverse position of the derailer switch; set the graphic color of the freight yard loading and unloading line; set the color of the equipment level crossing automatic control column machine and highway signal light; set the color of the graphic element of the train gate; set the color of the trackside magnetic steel graphic element; set the color and status of the container box; set the color of the equipment graphic element and connecting line, etc.

[0106] (2) Obtain the geometric coordinates of the equipment elements: obtain the coordinates of the level crossing automatic control column machine respectively; obtain the coordinates of the electronic red card safety protection derailer, red card and radio frequency control elements; obtain the coordinates of the magnetic steel element.

[0107] The XML-formatted graphic files read by the display interface include points, curves, and / or charts. This means the display interface can display a large amount of monitoring data and comprehensive analysis data. This data can be presented in a variety of forms, such as points, curves, and / or charts, achieving data visualization. This intuitive display meets the need for user-friendly data viewing and analysis.

[0108] Specifically, among the large amount of statistical data that needs to be displayed on the display interface, examples of the data types that need to be presented in multiple ways are as follows: railway port digital freight yard system transmission, level crossing automatic control, electronic red card safety protection and magnetic steel status; statistical data on the operation of electronic red card safety protection derailers in the monitoring data of the railway port digital freight yard system, including the number of operations, number of failures and frequency.

[0109] Among them, the multi-dimensional presentation of data will be presented through points, lines, bar charts, pie charts, etc. according to the different types of data.

[0110] Among them, the data displayed through points has the characteristics of generating a certain event at a certain location or at a certain time, such as the operation information in the integrated dispatching and control system of the digital freight yard of the railway port and the client human-computer interface information.

[0111] The data displayed by the curve graph has the characteristics of data changes within a distance range or time range, such as the working status of level crossing automatic control and electronic red card derailer. Figure 11 As shown in the figure, it shows the working status statistics of the magnetic steel over a period of time. Figure 11 It can be seen that the magnet is in a fault state when it starts working, which is represented by a red straight line; it works in a normal state for the following period of time, which is represented by a green straight line; and it finally works in a suspected fault state, which is represented by an orange straight line.

[0112] The data displayed by pie charts and bar charts has the characteristics of statistical information within a certain time range and is used to display statistical information of data. Figure 12 The figure shows the working status of the automatic level crossing control system over a period of time. During this statistical period, the automatic level crossing control system was in a normal state 10 times (indicated by green); it was in a suspected fault state once (indicated by orange); and it was in a fault state twice (indicated by red). The figure clearly shows the working status of the automatic level crossing control system.

[0113] In this embodiment, the display interface serves as the interface between the operation and maintenance monitoring system and the user. Through it, the user can understand the operation status of the equipment in the railway port railway freight yard dispatching and control integrated system, obtain alarm and warning information on the health status of the equipment, and query and record equipment maintenance information. Its overall functions are as follows:

[0114] (1) The display interface, as a human-machine interface, can be deployed on a variety of devices and terminals. It can be deployed in the freight worker's studio at a railway freight yard as an equipment maintenance terminal, or it can be deployed in a freight station section-level maintenance center or a regional-level maintenance center as a line-level or regional-level operation and maintenance display module. At the same time, in order to maximize the user's need to view equipment operation and maintenance information anytime and anywhere when working on-site, the display interface can also be deployed on a tablet computer.

[0115] (2) The display interface adopts a C / S architecture, and establishes a network connection with the integrated dispatching and control system of the digital freight yard of the railway port as a client, and the integrated dispatching and control system of the digital freight yard of the railway port as a server. After the display interface is started, it will automatically try to establish a network connection with the integrated dispatching and control system of the digital freight yard. Each display interface process will only establish an end-to-end network connection with the integrated dispatching and control system of the digital freight yard when running. After the connection is successfully established, it will remain until the interface program is closed. All information exchanges between the integrated dispatching and control system of the digital freight yard and the display interface are completed through this connection. If the network connection is interrupted, the display interface will automatically try to re-establish the connection with the integrated dispatching and control system of the digital freight yard until the connection is successfully established or the interface program is closed.

[0116] (3) The digital freight yard dispatching and control integrated system processes a large amount of data, including equipment monitoring information, fault diagnosis information, alarm information, and maintenance record information of one or more railway freight yards. Correspondingly, the computer system where the display interface is deployed has limited computing power (the display interface may be deployed on a laptop or tablet), and the network bandwidth is also limited (the display interface and the server may be connected through a public network or a 5G network). Based on the above reasons, in order to reduce unnecessary data processing and data transmission volume and ensure the efficient and smooth operation of the interface, it is necessary to streamline and reasonably arrange the data sent by the digital freight yard dispatching and control integrated system to the display interface so that it can be sent on demand. To achieve this goal, the display interface uses two mechanisms to ensure data transmission efficiency. The first is the data compression mechanism. All application layer data sent between the display interface and the digital freight yard dispatching and control integrated system are compressed to effectively utilize the network bandwidth. The second is the message subscription and unsubscription mechanism. The display interface will analyze the user's operation based on the user's operation, determine the data range that the user is concerned about, and send data subscription messages to the digital freight yard dispatching and control integrated system to request the corresponding data.

[0117] (4) The display interface can not only display and update real-time data, but also has a historical playback function, which is also achieved through message subscription and unsubscription. Users can replay the status, alarm information, and health status analysis information of the device within a certain period of time in the past by setting the playback start and end time on the interface. During the playback process, users can adjust the playback rate and can pause and resume the playback process at any time.

[0118] (5) The display interface can show the instantaneous status of the line or equipment. The so-called instantaneous status refers to the status of the equipment or connection at a certain point in time. For the user, the instantaneous status highlights the status of the object he is concerned about at a specific moment. The instantaneous status displayed on the display interface is as follows: the occupancy status of the track section of the freight yard loading and unloading line, the status of the level crossing automatic control column machine, the status of the level crossing automatic control highway signal machine, the status of the emergency closing and opening buttons of the level crossing automatic control column machine, the working status of other equipment, and the connection status between equipment.

[0119] (6) The display interface mainly displays these transient states through graphics supplemented by text descriptions. The graphics include: freight yard line diagrams, freight yard station diagrams, equipment logic diagrams, and equipment connection diagrams. The main function of the text description is to assist the graphics in making the description more precise and eliminate the ambiguity of the expression.

[0120] (7) The display interface can display the experienced status of the freight yard line or equipment. The so-called experienced status refers to the process of the status that the equipment or connection has experienced within a certain time period. For the user, the experienced status highlights the state change process of the object he is concerned about within a specific time period. Examples of the experienced status content displayed on the display interface are as follows: user operation record information on the equipment, record information generated during the operation of the equipment, equipment alarm record information, interaction record information between equipment, and equipment health status warning information obtained through comprehensive analysis. The display interface mainly displays the experienced status through lists and tables. The list display method mainly highlights the time or status change information arranged in chronological order. The table display method is mainly used to display structured data with multiple field items.

[0121] (8) The display interface can display the statistical information generated by the digital freight yard dispatching and control integration system.
