Description

Technical Field

[0001] The present invention relates to the field of rail transit vehicle HMI screen monitoring applications, and in particular to a configuration tool and method for a rail passenger car driver screen. Background Art

[0002] This patent focuses on advanced PHM (Prognosis and Health Management) systems in the rail transit sector, particularly the innovative solution of replicating the HMI (Human Machine Interface) functions of subway train cabs to ground-based PHM platforms. Currently, while this system is widely used for real-time monitoring, in-depth analysis, and accurate prediction of the health status of train equipment, aiming to detect potential faults in advance and immediately initiate maintenance plans, providing comprehensive support for rail transit operations, it still faces the bottleneck of insufficient visualization of train operation data on the PHM platform. This limitation directly leads to insufficient remote monitoring and fault diagnosis capabilities, which in turn restricts the PHM platform's potential to improve operational efficiency. By replicating the subway train cab HMI to the ground-based platform and enhancing data visualization, users can intuitively monitor and analyze the train's operating status from the driver's perspective. Improving monitoring efficiency and analysis accuracy is an urgent problem that needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a driver screen configuration tool and method for replicating the HMI of a subway train cab to a PHM platform. Its core purpose is to improve fault prediction and health management capabilities and enhance remote monitoring and fault diagnosis capabilities.

[0004] In response to the problems existing in the operation and maintenance of subway trains, the present invention proposes the following solutions:

[0005] A configuration tool for a railway passenger car driver screen, comprising:

[0006] Parameter management module, used to manage rail vehicle status data dictionary and standardized data;

[0007] Product parameter management module, used to manage basic data of rail vehicle products;

[0008] The data item management module combines parameter data and product data to form data item points for the driver screen configuration tool;

[0009] Component generation module, used to convert the original driver screen interface into a WEB component;

[0010] Component binding module, used to combine components and data items, and bind the relationship between components and data items;

[0011] The component rendering module is used to render the component into a WEB page and provide front-end display;

[0012] Fault diagnosis module, used for playback and real-time display on the driver's screen when the fault occurs;

[0013] The parameter management module structures the rail vehicle status data according to data standards and outputs it to the data item management module. The data item management module combines the product data provided by the product parameter management module to generate standardized data item points and establishes associations with the component binding module through the dynamic mapping engine;

[0014] The component generation module parses the driver screen's native interface into a configurable web component. Its properties are connected to the data item points output by the data item management module through two-way data binding. The component rendering module generates a responsive interface adapted to web, mobile, and large-screen monitoring based on the binding relationship.

[0015] The component rendering module projects the driver's screen interface to the status monitoring page of the ground platform in real time, and records operation logs and data snapshots at the same time. When the fault diagnosis module triggers an alarm, it automatically retrieves the historical values ​​of the related data items, marks abnormal data points through the time series comparison algorithm, and restores the driver's screen status at the time of the fault. Among them, status monitoring is carried out from the driver's perspective and classified according to subsystems to provide users with real-time and accurate train operation information. When a fault occurs, the system uses a visual method to display the faulty system and components to help users diagnose the cause of the fault.

[0016] Furthermore, the rail vehicle status data managed by the parameter management module includes speed, brake pressure, and motor temperature.

[0017] Furthermore, the basic data of rail vehicle products managed by the product parameter management module specifically include vehicle model and vehicle number.

[0018] A method for configuring a railway passenger car driver screen, comprising: combining a railway vehicle status data dictionary and standardized data with a railway vehicle product technical data set to form data item points for a driver screen configuration tool;

[0019] The original driver screen interface is converted into web components and data items are connected through two-way data binding. Based on the binding relationship, a responsive interface is generated that is suitable for web, mobile terminals, and large-screen monitoring.

[0020] The driver screen interface is projected in real time onto the status monitoring page of the ground platform, while recording operation logs and data snapshots. When an alarm is triggered, the historical values ​​of related data items are automatically retrieved, abnormal data points are marked through a time series comparison algorithm, and the driver screen status at the time of the fault is restored. Among them, status monitoring is carried out from the driver's perspective and classified according to subsystems to provide users with real-time and accurate train operation information. When a fault occurs, the system replays and displays the faulty system and components through visual methods to help users diagnose the cause of the fault.

[0021] The positive effect of this invention is that by effectively replicating the train cab HMI to the PHM platform, real-time display of key data and information of train operation is achieved, so that operation and maintenance personnel can obtain train status information in a more intuitive and convenient way, enhance the train operation monitoring and fault diagnosis capabilities, and further improve the reliability and safety of train operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 This is a diagram of the configuration tool architecture of the present invention. DETAILED DESCRIPTION

[0023] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0024] The original intention of the invention and the specific solutions are described as follows:

[0025] (1) The real-time status of the cab HMI is not synchronized with the operating information obtained by the operation and maintenance personnel:

[0026] Specific problem: In traditional methods, there is a delay between the operating status information obtained by the subway train cab HMI and the operation and maintenance personnel, making it difficult for the operation and maintenance personnel to obtain the latest status of the train in a timely manner, affecting the accuracy of fault prediction and health management.

[0027] Solution: Through the driver screen configuration tool, cab operating information is synchronized with the PHM platform in real time, ensuring that operation and maintenance personnel can accurately obtain real-time train operation dynamics and improve the accuracy of fault prediction and health management.

[0028] (2) Insufficient remote monitoring and fault diagnosis capabilities:

[0029] Problem: The functions of the current subway train remote monitoring and fault diagnosis system are not sufficient, making it difficult to achieve comprehensive monitoring and rapid diagnosis of the train's operating status.

[0030] Solution: After replication, the PHM platform can display train operating parameters, fault alarm information, and operation records in real time, making it easier for operation and maintenance personnel to remotely monitor train status, quickly locate and diagnose faults, and improve remote monitoring and fault diagnosis capabilities.

[0031] Reference Figure 1 The present invention provides a configuration tool for a rail vehicle driver screen, comprising: a parameter management module for managing a rail vehicle status data dictionary and standardized data; a product data management module for managing rail vehicle product basic data, including information such as vehicle model and vehicle number; a data item management module for combining parameter data and product data to form data item points for a driver screen configuration tool; a component generation module for converting an original driver screen interface into a WEB component; a component binding module for combining components and data item points to bind the relationship between components and data item points; a component rendering module for rendering components into WEB pages to provide foreground display; status monitoring, which is a scenario of component rendering, and the driver screen page is implanted into the status monitoring page through the component rendering function; fault diagnosis, which is another scenario of component rendering, and the driver screen playback and real-time display at the time of fault occurrence are achieved through the fault diagnosis module; the present invention realizes real-time monitoring and fault diagnosis from the rail vehicle driver screen to the ground platform through the relevant functions and connections of the above modules, forming a complete "vehicle-ground integration" HMI monitoring system.

[0032] Among them: the parameter management module structures the rail vehicle status data (such as speed, brake pressure, motor temperature, etc.) according to data standards and outputs it to the data item management module; the data item management module combines product data (vehicle model, number, etc.) to generate standardized data item points (such as T18_VCB_Trip_Voltage) and establishes an association with the component binding module through the dynamic mapping engine.

[0033] The component generation module parses the driver screen native interface (such as Qt / C++) into a configurable Web component (Vue / React), whose properties are connected to the data item points output by the data item management module through two-way data binding; the component rendering module generates a responsive interface adapted to Web, mobile terminals, and large-screen monitoring based on the binding relationship.

[0034] The component rendering module projects the driver screen interface to the status monitoring page (ground platform) in real time, while recording operation logs and data snapshots; when the fault diagnosis module triggers an alarm, it automatically retrieves the historical values ​​of related data items, marks abnormal data points through a time series comparison algorithm, and restores the driver screen status at the time of the fault.

[0035] Among them, status monitoring starts from the driver's perspective and is classified according to subsystems to provide users with real-time and accurate train operation information. When a fault occurs, the system uses a visual method to display the faulty system and components to help users diagnose the cause of the fault.

[0036] The present invention provides specific embodiments as follows. It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.

[0037] 1. System deployment: prepare a Linux or Windows-based server and deploy the front-end and back-end environments. The system configuration must meet the requirements of CPU ≥ 8 cores and memory ≥ 16GB;

[0038] 2. Data preparation: The parameter management module compiles Excel spreadsheets based on the vehicle-ground landing agreement and imports them into the system, creating a data dictionary containing fields such as parameter code, parameter name, and system. The product data management module uses a MySQL database to store basic information such as vehicle model and group relationship. The data item management module manually associates parameter data with product data, generates standard data item points, and publishes them to the system. The component generation module converts the driver screen interface into a Vue component and generates the corresponding TypeScript type definition file. The component binding module uses RxJS to implement two-way binding between data streams and UI components, and establishes a binding relationship table containing data validation rules (such as range checking and rate limiting).

[0039] 3. System testing: by collecting data in real time, checking the accuracy of the driver screen and ground display against the corresponding system parameters;

[0040] 4. System operation and maintenance, continuous system updates through testing and verification.
