Integrated automatic test system of on-board computer of civilian airliner

Abstract

An integrated automatic test system of a on-board computer of a civilian airliner, which comprises a test controller, a test instrument collection, a switching system, and a signal interface device, wherein the test controller is connected with the test instrument collection and the switching system through an instrument control bus; the test instrument collection and the switching system are connected with the signal interface device; the signal interface device is used for being connected with a to-be-tested object of on-board electronic equipment of the to-be-tested civilian airliner; the test controller comprises a test module, a test management module, a test function library module, a driver module, and an operating system module; the test module, the test management module, the test function library module, the driver module, and the operating system module are classified into five levels during operation. The integrated automatic test system adopts the modularized design in the hardware architecture and the hierarchical design in the software architecture, so as to allow the modification and the extension of hardware and software to be more convenient, facilitate the improvement of resource reusability of the test system, and low the cost.

Description

technical field [0001] The invention relates to an automatic test system for electronic components of a civil aviation aircraft, in particular to a large-scale general comprehensive automatic test system for an on-board computer of a civil aviation aircraft. Background technique [0002] Automatic test system refers to a general term for a class of systems that can automatically complete excitation, measurement, data processing, display and output test results under the control of a computer. The automatic test system is used to complete the performance test of the unit under test (UUT for short), and can also be expanded into a diagnostic system based on the analysis of test results, diagnosis and location of faults. According to the test object, the automatic test system is divided into: special automatic test system and general automatic test system. General automatic test system: It is a test system developed for a certain field and the object to be tested. [0003] At...

Problems solved by technology

But at the same time, it cannot be ignored that, on the one hand, the introduction of these technologies requires a large amount of project investment funds, and it is difficult to achieve a reasonable balance between benefits and risks. On the other hand, manufacturers usually use some special boards for Technical blockade, high post-maintenance costs

In addition, due to changes in the market and testing requirements of electronic equipment, it is very complicated to perform hardware configuration and test software expansion modification on the above-mentioned imported system
