Embodiment Construction

[0046] The traditional aviation software upgrade is to connect the upgrade device with a single module. The upgrade device is connected to the module to be upgraded through a serial port or a network port. The upgrade of a module requires one or more upgrade operations, and the upgrade operation of the product is cumbersome and complicated.

[0047] Such as figure 1 As shown, the present invention is based on the idea of ​​unified upgrading of software and configuration data, and centrally stores the software and configuration data of the system in a large-capacity module, and other modules obtain software and configuration data from the large-capacity storage module through a Fiber Channel (Fibre Channel, FC) network The configuration data is solidified in the FLASH space of this module.

[0048] Centralized software upgrade is divided into two parts: the software client running on the upgrade module and the software upgrade server running on MMM.

[0049] After the system i...

Abstract

The invention discloses a centralized software upgrading method, device and system for an avionics system. The method comprises the following steps: sending a software upgrading request of a client toan MMM, wherein the software upgrading request comprises a module identifier of an application processing module; wherein one application processing module is only provided with one client, and one client is provided with a plurality of pieces of software; receiving upgrading software information of the client, sent by the MMM; determining which software of the client needs to be upgraded according to the upgrading software information; when it is determined that the target software of the client needs to be upgraded, sending a software path and a module identifier of the target software needing to be upgraded to the MMM; receiving upgrade software sent by the MMM; and replacing the target software of the client with the upgrade software. The method can effectively solve the problem thattraditional distributed software upgrading is complex and cumbersome, and the reliability and maintainability of an avionics system are improved.

Description

technical field [0001] The invention belongs to the field of aviation, and relates to a centralized software upgrading method, device and system for an avionics system. Background technique [0002] The integrated task processor is the core basic platform of the avionics system. It has comprehensive processing capabilities of data, graphics / images, and videos, as well as system storage capabilities, and operates sensor fusion, situation assessment, offensive combat management, defensive response management, and weapon delivery fire control calculations. and other computing tasks. Among them, the mass memory module (Mass Momory Modlue, MMM) stores the big data and software image of the avionics system. The traditional software upgrade method is that each module obtains software from the upgrade device through Ethernet or serial port, and solidifies it in the local FLASH space. The upgrade of a module requires one or more upgrade operations, and the upgrade operation of the ...
