Embodiment 1

[0047] The vehicle maintenance plan management method based on the vehicle health diagnosis in this embodiment, such as figure 1 shown, including the following steps.

[0048] S10. Collect vehicle data

[0049] By using the vehicle's existing control network and / or vehicle maintenance network, fully collect all data monitored by various systems on the vehicle, including sensor data, various switch contact data, image information data, and microcomputer unit monitoring and diagnosis data.

[0050] S20, data processing

[0051] Process the vehicle data collected in S10, and form the processed data into a basic database;

[0052] The specific steps of data processing include:

[0053] S21. Data de-duplication. For signals from different sources but with the same meaning, the repeated signals are combined according to the method of source address ID identification and variable name de-duplication to avoid repeated processing of fault information;

[0054] S22. Data classificat...

Embodiment 2

[0079] The vehicle maintenance plan management system based on vehicle health diagnosis of this embodiment includes:

[0080] A data acquisition unit, which is arranged on the train and is used to collect sensor data, various switch contact data, image information data and microcomputer unit monitoring and diagnosis data in the vehicle;

[0081] The data processing unit, which is arranged on the train and is connected to the data acquisition unit by signal, is used to receive the acquisition data transmitted by the data acquisition unit, and perform deduplication, classification, extraction and interpolation processing on the data, and construct the processed data as basic database;

[0082] a diagnosis unit, which is signal-connected with the data processing unit, used for analyzing the data of the basic database, and judging whether maintenance is required according to the user-defined information;

[0083] The information association unit, which is connected with the diagn...

Embodiment 3

[0086] The computer-readable storage medium of this embodiment is used to store non-transitory computer-readable commands. When the non-transitory computer-readable commands are executed by a computer, the method for managing a vehicle maintenance plan based on vehicle health diagnosis in Embodiment 1 is implemented. A step of.

[0087] The computer-readable storage medium in this embodiment may be an internal storage unit of the terminal, such as a hard disk or a memory of the terminal; the computer-readable storage medium in this embodiment may also be an external storage device of the terminal, such as a plug-in device equipped on the terminal. hard disk, smart memory card, secure digital card, flash memory card, etc.; further, the computer-readable storage medium may also include both an internal storage unit of the terminal and an external storage device.

[0088] The computer-readable storage medium of this embodiment is used to store computer programs and other programs...

Abstract

The invention discloses a vehicle maintenance plan management method and system based on vehicle health diagnosis, and belongs to the technical field of urban rail transit vehicles. The method comprises the following steps: S10, collecting vehicle related data; s20, data processing: processing the vehicle data and forming a basic database by using the processed data; s30, abnormal state diagnosis: analyzing the data of the basic database, and judging whether maintenance needs to be performed or not according to user-defined information; s40, information association: establishing a relational mapping table of the data and the corresponding minimum maintainable unit in the basic database, and establishing a relational mapping table of the minimum maintenance item point and the minimum maintainable unit; s50, a maintenance plan is initialized, an initial maintenance task schedule is constructed, and initial maintenance plans of various stages in the whole life cycle of the vehicle are completed; and S60, dynamically managing the maintenance plan. The problem of low efficiency in the maintenance process is solved, and the maximization of the utilization effect of the vehicle health management data and the effective feedback of the field maintenance information on the vehicle health management optimization are realized.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit vehicles, and more particularly, relates to a vehicle maintenance plan management method and system based on vehicle health diagnosis. Background technique [0002] With the demand of rail transit users for intelligent and intelligent rail transit operation and maintenance, the development of vehicle health management system (or vehicle expert system) has been promoted. [0003] At present, the architecture and functional scope of the health management system have not yet been clearly defined. Many companies have put forward some explanations on the system architecture and functional scope based on their own research and development results. ) system, as a part of health management, provides information support for vehicle equipment maintenance and maintenance, which mainly includes BOM management unit, maintenance manual management unit, LCC management unit, maintenance plan management...
