Abstract

The invention discloses a testing method of an aircraft embedded type real-time diagnosis reasoning algorithm. The testing method comprises the following steps of enabling a main control device to register a to-be-verified diagnosis reasoning algorithm; enabling the main control device to integrate the registered to-be-verified diagnosis reasoning algorithm into an embedded type target aircraft; enabling a data simulating device to obtain corresponding actual fault data from a fault injection system of a test bench according to a fault injection command for injecting the actual fault data sent by the main control device; reasoning and computing the actual fault data by the embedded type target aircraft by using the to-be-verified diagnosis reasoning algorithm, and sending the computing result to the main control device; enabling the main control device to analyze the computing result, and evaluating the property of the to-be-verified diagnosis reasoning algorithm. The testing method has the advantage that the problem of difficulty in verification of the real-time diagnosis reasoning algorithm on the aircraft in the prior art is solved.

Description

technical field [0001] The invention relates to the field of aircraft fault diagnosis, in particular to an aircraft embedded real-time diagnostic reasoning algorithm test method. Background technique [0002] With the increasing functional complexity and system complexity of new aircraft, the fault diagnosis and health management systems for each system are becoming more and more complex. At the same time, the aircraft health management system puts forward higher requirements for the accuracy and efficiency of the diagnostic reasoning process. Therefore, in the development stage, designers need to face higher performance requirements, which brings more difficulties to development and production. [0003] Fault diagnosis for airborne equipment is a technology involving multiple equipment, from data collection for the equipment under test, to importing equipment status information into the regional manager for diagnostic processing, and finally sending the diagnostic results ...
