On-line detection equipment and method for fly-by-wire flight control system

Abstract

The invention discloses on-line detection equipment and an on-line detection method for a fly-by-wire flight control system, and belongs to the field of aeronautical engineering testing. The on-line detection equipment is characterized by consisting of a signal transmission and disconnection device and flight testing interface equipment, wherein the signal transmission disconnection device is used for completing transmission and disconnection of related crosslinking signals of a fly-by-wire flight control computer; the signal transmission disconnection device is of a modular combined structure and consists of a plurality of unit modules which are relatively independent in structure and relatively complete in function; each independent unit module can complete transmission and disconnection of similar or approximate signals; the flight testing interface equipment consists of an operation controller, a flight testing data bus interface plate, an onboard data bus interface plate, an analog quantity signal interface plate, a switching value signal interface plate, a digital value signal interface plate, a tester bus or a computer bus and detection application software, and is used for extracting, analyzing and displaying and output parameter information of the fly-by-wire flight control computer in various tests on the fly-by-wire flight control computer or the fly-by-wire flight control system.

Description

technical field [0001] The invention relates to a flight control system testing device and method, in particular to an online testing device and method for a fly-by-wire flight control system, belonging to the field of aeronautical engineering testing. Background technique [0002] In the design and development of aircraft, especially in the design and development of the important functional system of the aircraft - fly-by-wire flight control system, it is often necessary to carry out various tests, such as: component tests of fly-by-wire flight control computers, fly-by-wire flight control Subsystem comprehensive test, flight control system iron bird integration test, flight control system on-board ground test, etc. In the above-mentioned tests, it is usually necessary to develop a corresponding test environment according to the test object—fly-by-wire flight control computer or fly-by-wire flight control system, and carry out the interface of fly-by-wire flight control com...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned test environment is often designed and constructed for a single test object—the fly-by-wire flight control computer or the fly-by-wire flight control system. The test test environment is designed and built once and can only be used as a whole for one time.
