Embodiment Construction

[0055] The present invention will be described in further detail below.

[0056] 1. Design an extended 5-level health monitoring system based on the ARINC653 standard. It is used for the fault diagnosis, processing, and reporting mechanism of the airborne avionics system from CPU software tasks to equipment modules. Comprehensive diagnostics for comprehensive processing and task reachability.

[0057] 2. The design of the five-level health monitoring system, according to the health event processing level from small to large, is divided into: (1) task-level health monitoring functional area (2) partition-level health monitoring functional area (3) module-level health monitoring functional area (4) equipment Level comprehensive diagnosis function area (5) Aircraft level health processing function area;

[0058] 3. In the aircraft airborne network, an extended 5-level health monitoring system based on the ARINC653 standard is in many links of the airborne equipment network. Su...

Abstract

The invention belongs to the aircraft avionics system technology and relates to a health monitoring system of avionic electronic equipment based on an ARINC653 standard. The health monitoring system adopts a mode of input step by step, diagnostic decision and stage treatment to process anomalous events, performs comprehensive diagnosis from a software task stage to an operation system and from an avionic electronic equipment layer to a full-aircraft system, and adopts a classification layered mode to assign fault events to processing steps of different stages according to a health monitoring stage, and processing permissions are enlarged step by step according to the health monitoring stage. By means of the mode of the stage treatment and report stage by stage, airborne health management of an aircraft is effectively achieved. Safety of fault processing is ensured through the processing permissions of different stages, and processing efficiency on the system fault events and sensing of the aircraft on the health states are improved by reporting the events stage by stage. Therefore, fault diagnosis recovery capability of the aircraft is effectively improved, and testability and safety of the aircraft are strengthened.

Description

technical field [0001] The invention belongs to aircraft avionics system technology, and relates to a health monitoring system of airborne electronic equipment based on the ARINC653 standard. Background technique [0002] With the rapid development of integrated modular airborne electronic system (Integrated Modular Avionics, IMA). Airborne electronic technology has gone through several stages of development. After the third generation of aircraft, airborne computers widely adopt real-time embedded operating system (RTOS). With the rapid development of fourth-generation and fifth-generation combat aircraft and unmanned aerial vehicles, modern aircraft avionics are developing rapidly in the direction of integration, modularization, and intelligence. Aiming at the needs of portability, reusability and high reliability of the new aircraft airborne electronic system, the American Aeronautical Electronics Committee proposed the application programming interface standard Arinc653...
