[0025] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0026] The following describes the implementation methods of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0027] like Figure 1As shown, an embodiment of the present invention provides a management and maintenance system for an airborne information system, including a configuration process and an operation process. The configuration process includes a maintenance member information configuration module 101, a fault information configuration module 102, a maintenance self-check information configuration module 103, and a configuration information configuration module 104; the operation process includes a fault diagnosis module 201, a configuration management module 202, a life cycle management module 203, a maintenance self-check module 204, a fault history management module 205, an aircraft parameter publishing module 206, and an interactive display module 207.

[0028] (1) Configuration process

[0029] The configuration process is the basis of this method, providing system-related information for the operation process, separating the operation process from the configuration process, and realizing the configurability of the maintenance function through the decoupling of the process and the operation process. By designing the maintenance function as a configuration-based architecture, the function can be increased or decreased by simply adding or deleting the corresponding configuration information of the device or module without changing the functional architecture, thereby realizing the scalability of the maintenance function. The configuration information of each module in the configuration process is shown below.

[0030] Maintenance member information configuration module 101: the equipment or module information that needs to be maintained in the airborne information system, the present invention defines the equipment or module that needs to be maintained as maintenance members, and the equipment or module information is defined as maintenance member information. The maintenance member information configuration module serves as input information for other modules.

[0031] Fault information configuration module 102: This module mainly completes the configuration of the maintenance member fault diagnosis logic. Fault diagnosis logic is the basis of fault diagnosis. By classifying faults into system-level faults, device-level faults and module-level faults, important system-level faults are reported to the airborne maintenance system using the ARINC429 bus with bandwidth restrictions, while more detailed device-level and module-level faults are displayed through the interactive display module, realizing hierarchical diagnosis of faults and making the fault diagnosis function more efficient. The fault information configured by this module is the input of the fault diagnosis module.

[0032] Maintenance self-check information configuration module 103: This module configures the fault information of the airborne information system that requires maintenance personnel to perform interactive detection, including maintenance self-check items, interactive detection methods and related operations. The fault information configured by the maintenance self-check information is a subset of the fault information configured by the fault information module 102, which is a fault that requires auxiliary operation by maintenance personnel. The auxiliary operations required during the maintenance self-check process need to be pre-configured. The maintenance self-check information configuration module also needs to complete the configuration of the maintenance self-check conditions.

[0033] Configuration information configuration module 104: This module completes the factory configuration of the airborne information system maintenance members and is the input of the configuration management module. The factory configuration is the configuration information of the airborne information system when it leaves the factory, including the software and hardware configuration information of the components and modules, and is used to record the version status of the equipment and modules. The factory configuration information serves as the initial configuration information of the airborne information system.

[0034] (2) Operation process

[0035] The operation process of this solution is responsible for calculation and display functions, and the information that needs to be calculated and displayed comes from the output of the configuration process. The functions of each module in the operation process are relatively independent, so that the functional modules are decoupled from each other except for the interactive display module, and do not affect each other. The interactive display module only reads and displays the output information of each module as input information, and there is no conflict between functions. The functional design of each module is shown below.

[0036] Fault diagnosis module 201: This module performs fault diagnosis in the operation of the maintenance function according to the output of the fault information configuration module. If the diagnosis result shows a fault, the fault information is recorded; otherwise, the fault record information is the input of the interactive display module.

[0037] Configuration management module 202: This module uses the configuration information output by the configuration information configuration module as the baseline configuration, and compares it with the current configuration information of the airborne information system to form configuration change information and the latest configuration information. The configuration change information and the latest configuration information are the input of the interactive display module.

[0038] Lifecycle management module 203: Lifecycle data is important maintenance information of equipment or modules, including power-on time and power-on times. Lifecycle data can be used for fault analysis or life prediction. The lifecycle management module is used to collect and record lifecycle data of each equipment and module of the airborne information system. Lifecycle data is used as input of the interactive display module.

[0039] Maintenance self-check module 204: This module uses the maintenance self-check information output by the maintenance self-check information configuration module as input. Under certain conditions, the maintenance personnel interact with the configuration information to detect whether there is a fault or not, and the result is used as one of the calculation results of the fault diagnosis. The maintenance personnel implement the maintenance self-check function through the interactive display module.

[0040] Fault history management module 205: Fault history is the fault information recorded by each device or module. Through interactive operation with interactive display module 207, the fault information recorded by the maintenance member is acquired. The acquired fault history can be used as input for further fault analysis.

[0041] Aircraft parameter publishing module 206: This module receives the aircraft parameter status data published by the airborne maintenance system, and composes the aircraft parameter message with the maintenance information required by each maintenance member of the airborne information system, and transmits it to the member who configures the output of the maintenance member information. Aircraft parameters are maintenance-related aircraft parameters, which are used as the input information of the member and the attribute information such as the time when the member records the fault. The aircraft parameter publishing module unifies the information source required for the maintenance of the airborne information system and maintains the validity of the recorded data.

[0042] Interactive display module 207: The interactive display module implements the interactive display function of the maintenance function through the airborne information system display terminal. The input of the interactive display module is the output of the maintenance member information configuration module, the fault diagnosis module, the configuration management module, the life cycle management module and the maintenance self-check module. The interactive display module is divided into fault information display, configuration information display, life cycle display, fault history management and maintenance self-check functions according to the function. The interactive display module provides the maintenance personnel with a maintenance interface of the airborne information system, which facilitates the display and operation of maintenance information. Each function item configured by the interactive display module is realized through the operation instructions of the maintenance personnel.

[0043] Based on the study of the physical composition of the airborne information system, the present invention proposes a management and maintenance system for the airborne information system that is configurable, hierarchical, and displayable. In view of the large-capacity storage function of the airborne information system and the bandwidth limitation of Arinc429, a fault location hierarchical strategy is proposed to report system-level fault information to the airborne maintenance system, and display more detailed equipment-level and module-level fault information to further improve fault analysis and location; in view of the requirement for the scalability of the airborne information system function, a configurable design of the maintenance information of each component unit and module of the airborne information system is proposed, which can facilitate the expansion of the airborne information system function; since the airborne information system has a display function, it is proposed to display maintenance-related information, such as fault information, configuration and other data, to facilitate maintenance personnel to view and analyze.

[0044] The implementation process of the embodiment of the present invention is divided into 11 parts, namely, maintenance member information configuration, fault information configuration, maintenance self-check information configuration and configuration information configuration, fault diagnosis, configuration management, life cycle management, maintenance self-check, fault history management, aircraft parameter release and interactive display.
