Description

Technical Field

[0001] The invention belongs to the technical field of rail vehicle and rail passenger car PHM system (fault prediction and health management system), and in particular relates to a rail passenger car pattern configuration tool. Background Art

[0002] The PHM system plays an increasingly important role in the field of rail transit. The development of the PHM system provides strong support for the safe operation and maintenance management of rail transit. The comprehensive monitoring of the train status by the PHM system is the basis for ensuring the safe operation of the train.

[0003] Currently, the PHM system monitors rail vehicles more and more deeply, and the collected data is more and more comprehensive, but there is still a lack of effective methods to associate train data with train schematics (circuit diagrams, pneumatic diagrams, etc.) to help users monitor and analyze the operating status of trains from the perspective of train operating principles. Summary of the invention

[0004] The present invention aims to solve the problem of lack of effective tools to associate train data with train schematics, thereby providing a rail passenger car drawing configuration tool, through which users can freely configure train schematics (circuit diagrams, pneumatic diagrams), thereby monitoring important components in the train schematics, making static schematics dynamic, and realizing monitoring, analysis and fault diagnosis of train component levels and principle layers.

[0005] To achieve the above-mentioned purpose of the invention, the present invention provides a railway passenger car pattern configuration tool, including a data item management module, a pattern processing module, a pattern configuration module, and a monitoring and analysis module;

[0006] The data item management module is used to query the parameters corresponding to the components in the circuit diagram and create data items. The data items are structured according to the data structure of the rail passenger car. After the data items are associated with the corresponding components, the system automatically obtains the parameter data of the corresponding car for calculation;

[0007] The pattern processing module is used for the user to use the editor to process the format and pattern data of the pattern, convert the pattern into SVG format, and pre-process the monitored target components to construct the display state and display style of the components at different parameter values;

[0008] The pattern configuration module is used by the user to complete the association of data items with components corresponding to the pattern, logic configuration and state configuration;

[0009] The monitoring and analysis module is used to perform status monitoring and fault diagnosis on the train schematic diagram in the PHM system after the diagram configuration is completed.

[0010] Furthermore, the data association of the pattern configuration module is that the user selects an element in the pattern and associates it with a prepared data item, and the system automatically obtains the data of the corresponding car according to the bound data item.

[0011] Furthermore, the logic configuration of the pattern configuration module is to input a judgment condition expression through a logic configuration tool after associating the data, and configure the calculation logic of the associated parameters for the component.

[0012] Furthermore, the state configuration of the pattern configuration module is to configure the component states corresponding to different judgment conditions, and complete the construction of the mapping relationship between the train data and the component state display.

[0013] Furthermore, the status monitoring of the monitoring and analysis module is to obtain relevant train data in real time, and dynamically display the status of pattern components in real time according to the configured calculation logic and status display logic.

[0014] Furthermore, the fault diagnosis of the monitoring and analysis module is that when a fault occurs, the system automatically displays the state of the pattern components when the fault occurs, to help the user locate the cause of the fault.

[0015] The positive effect of the present invention is that based on the data characteristics of rail passenger cars and the PHM system's demand for comprehensive monitoring of trains, the train data is effectively associated with the train schematics (circuit diagrams, pneumatic diagrams, etc.), and accurate monitoring of the train schematic component level is achieved, helping users to monitor the entire train operation and component-level operating status of the train in real time, so as to improve the monitoring, analysis and fault diagnosis capabilities of the PHM system. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 Configure tool architecture diagram for rail vehicle drawings; DETAILED DESCRIPTION

[0017] In order to better understand the purpose, structure and function of the present invention, a railway passenger car pattern configuration tool of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0018] The rail vehicle drawing configuration tool includes a data item management module, a drawing processing module, a drawing configuration module, and a monitoring and analysis module.

[0019] Data item management module: query the parameters corresponding to the components in the circuit diagram and create data items. The data items contain the same type of parameters for different carriages of the same model. The data items structure the parameters according to the data structure of the rail passenger car. After the data items are associated with the corresponding components, the system automatically obtains the parameter data of the corresponding carriage for calculation. The configuration of data items can greatly improve the configuration efficiency.

[0020] Drawing processing module: Users use the editor to process the drawing format and drawing data, convert the drawing into SVG format, and pre-process the monitored target components to build the display state and display style of the components at different parameter values. Through data processing, the system automatically identifies the target component and gives various states of the target component, so that users can configure the corresponding logic for different states of the component.

[0021] Drawing configuration module: Through the drawing configuration function, users can complete data association, logic configuration and status configuration:

[0022] (1) Data association: Users can select components in the drawing and associate them with prepared data items. The system automatically obtains the data of the corresponding car based on the bound data items.

[0023] (2) Logic configuration: After associating the data, use the logic configuration tool to enter the judgment condition expression and configure the calculation logic of the associated parameters for the component.

[0024] (3) Status configuration: Configure the component status corresponding to different judgment conditions to complete the construction of the mapping relationship between train data and component status display.

[0025] Monitoring and analysis module: After completing the diagram configuration, the train schematic diagram can be monitored and fault diagnosed in the PHM system:

[0026] (1) Status monitoring: The system obtains relevant train data in real time and dynamically displays the status of pattern components in real time according to the configured calculation logic and status display logic.

[0027] (1) Fault diagnosis: When a fault occurs, the system automatically displays the component status at the time of the fault to help users locate the cause of the fault.
