At the same time, it can truly reflect the status of on-site equipment in the event of a fault, so as to facilitate the identification of the fault category. When handling the fault, the relevant equipment can be operated on the power system diagram to adjust the operation mode. The fault alarm bar 6 is used to display the real fault alarm information when a fault occurs, and at the same time generate alarm information to remind professionals to make corresponding responses.

The prompt window 8 is used to prompt the information to be notified in the next step of the electric ring dispatch fault, the equipment that needs to be operated on the power system diagram, and precautions;

[0083] The fault alarm bar 6 includes account information 9, an alarm display area 10, and an event confirmation bar 11;

[0084] The account information 9 is used for the electric ring dispatch to log in to the account, display the electric ring dispatch account information, operator information and real-time time, the alarm display area 10 is used to display various alarm information in the case of a fault, including the alarm level, occurrence time, fault type, system, station, fault location, event description, and the event confirmation column 11 is used for fault event query, fault alarm sound confirmation, power system diagram zooming in and out, and left and right translation in the case of a fault;

[0085] The event confirmation column 11 includes fault event confirmation 12, fault alarm sound confirmation 13, power system diagram zoom in and out 14;

[0086] The fault event confirmation 12 is used for generating a large amount of alarm information of related equipment in the case of a fault, and the electric ring dispatcher checks the relevant alarm information and confirms the corresponding fault alarm information after the fault is handled. The fault alarm sound confirmation 13 is used for generating a fault alarm sound in the case of a fault to prompt relevant personnel to make a corresponding response. The power system diagram zooming in and out 14 is used to zoom in, zoom out, and translate the power system diagram locally, so that the electric ring dispatcher can check the equipment status;

[0087] The fault emergency 4 includes a power system diagram 15, a fault alarm bar 6, a head menu bar 7, and a fault handling prompt window 16;

[0088] The power system diagram 15 is used to display the status of on-site power equipment, so that professionals can be familiar with the equipment distribution and power supply status. At the same time, in the event of a fault, it truly reflects the status of on-site equipment to facilitate identification of the fault type. The fault handling prompt window 16 is used to prompt the power ring dispatcher to report the next step of the fault, the specific equipment operation and precautions;

[0089] like Figure 1-Figure 7 As shown, a method for implementing an emergency handling simulation system for urban rail transit power equipment failures includes the following contents:

[0090] The terminal user opens the power equipment failure emergency response simulation platform 1 through the Internet. First, the front-end page is realized, using the html text markup language as the basic language, the vue system framework to build the system framework login page 17, the line page 18, and the subway line interface 23;

[0091] The login page 17, the line page 18, and the subway line interface 23 are constructed based on the vue system framework. The login page 17 realizes the page jump to the line page 18 after login. The subway line interface 23 mainly realizes the loading of the svg line map 22 and the various fault navigation bars 19 of each station of Line 16.

[0092] The element component library implements system components such as the exit 20 button, the return 21 button, and the header menu bar 7;

[0093] The exit 20 button will execute the system exit operation and clear the user login information. We will use Vue combined with the relevant components of the Element component library to add this button to the page, realize the front-end and back-end data interaction through JavaScript computer language and jquery plug-in library language, and give it the exit function logic;

[0094] The back 21 button is used by users to return to the previously browsed page. We will use the relevant components and functions in the Vue framework and the Element component library, add a click event to it through the JavaScript computer language and the jquery plug-in library to call a custom function, so that it triggers the return to the previously browsed page;

[0095] The head menu bar 7 uses the menu component in the Element component library to create a menu bar at the head of the page. It contains three submenus. Users can navigate to different pages to switch pages by clicking on different menu items. The menu display and style are adjusted using the Element component library's own styles. The interactive functions are configured and implemented using the JavaScript computer language and the jquery plug-in library.

[0096] The dhtmlxgrid table component builds the fault alarm column 6 and the event column 24;

[0097] When the alarm bar 6 and event bar 24 have equipment failures, JavaScript and jQuery languages ​​are used to implement data interaction between the front and back ends, store the corresponding fault data in the back end, and obtain it from the back end to the fault alarm bar and event bar of the dhtmlxgrid table on the front end interface. Specifically, we will use jQuery's AJAX function to send a request to the back end to obtain the equipment failure information data. After obtaining the data, the dhtmlxgrid component is used to render the data in a table at the corresponding position of the web page. In this way, the user can intuitively see the equipment failure information, including a detailed description of the failure, the time of occurrence, the specific location of the failure, and other information;

[0098] Inkscape drawing software drawing power system Figure 5 、svg line diagram 22;

[0099] The power system Figure 5 , svg line diagram 22 Use Inkscape drawing software to draw the corresponding power system diagram and SVG line diagram, and configure parameters for different elements in the diagram, such as line color value red: energized, gray de-energized, line thickness value bus: 5px, line: 3px, switch position status value closing: red, closing success: red flashing, opening: green, opening success: green flashing, fault: yellow, communication interruption: blue, shape, etc. JavaScript and jQuery languages ​​are used at the same time to complete the interaction between the front and back ends. When the user clicks the switch, the front end will send the real-time switch status value information to the back end, and the back end will perform corresponding logical processing according to the status value, such as updating the status information of the switch in the database. At the same time, the front end will update the display status of the switch in the diagram according to the response of the back end;

[0100] For example, when a user clicks an element representing a switch, the front end will send a request to the back end through jQuery's AJAX function to tell the back end that the state of the switch has changed. After the back end completes the corresponding processing, it will give a response to the front end. Based on this response, the front end changes the color of the switch in the SVG image or other attributes representing the state to show whether the switch is on or off.
