Airborne fault management system

Abstract

The present invention discloses an airborne trouble management system. The airborne trouble management system includes a fault management computer and a fault storage computer; the fault management computer acquires fault data and sends the fault data to the fault storage computer for storing the fault data; the fault management computer includes three layers of software, namely an operating system and driving layer, a data access layer and a service logic layer; the operating system and driving layer provides an operating system and a plurality of different bus driving interfaces; the data access layer is used for calling corresponding driving interfaces to read the data messages of external devices from external buses and sending the data messages to the service logic layer and calling the driving interfaces to send encoded fault data sent by the service logic layer to the fault storage computer; and the service logic layer is used for extracting fault data from the data messages uploaded from the data access layer, encoding the fault data and sending the encoded fault data to the data access layer. With the airborne trouble management system of the present invention adopted, a fault management system which is in high real-time performance, high in reusability and good in expansibility and easiness in maintenance can be provided for modern large and medium-sized aircrafts.

Description

technical field [0001] The invention relates to avionics technology, especially for a fault management system constructed by using an embedded database in an embedded environment. Background technique [0002] The aircraft fault management system is a system that collects and uniformly manages the fault information of each subsystem of the aircraft in real time. In traditional aircraft, because there are fewer electronic devices on the aircraft and the fault information is relatively simple, a unified storage method for all faults is adopted. When the maintenance personnel check the fault, they will select and call out the relevant faults from the uniformly stored fault information for display. [0003] As the functions of avionics become more and more complex and the degree of equipment integration becomes higher and higher, the fault information of the equipment also increases exponentially. There are many faults, which make it inconvenient to use and difficult to meet th...
