An Automatic Test System for Avionics System

Abstract

The invention discloses an automatic testing system of an avionics system. The automatic testing system of the avionics system is connected to the tested avionics system (1). The automatic testing system of the avionics system is composed of an aerial carrier flight emulator (2), an external store simulator (3), a conducting exciter (4), a non-avionics system emulator (5), a testing general control platform (6), an each-target simulator (7), an integrated test system (8), a judging and recording system (9) and a prompting system (10). Real-time network connection is conducted on testing auxiliary devices such as the external store simulator, the each-target simulator, the conducting exciter and the aerial carrier flight emulator through the automatic testing system of the avionics system. Each testing auxiliary device is automatically controlled to generate a signal with a strict time series in each inspection step and judgment about data correctness is achieved through a method capable of being called searching type automatic judgment under the control of the testing general control platform so that automatic testing can be achieved. According to the automatic testing system of the avionics system, the efficiency of avionics system testing is effectively improved and the comprehensiveness of automatic testing is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of structural design and application of a test system for an avionics system, and in particular provides an automatic test system for an avionics system. Background technique [0002] At present, in the integration test of the avionics system, the judgment of the data flow is made by manual judgment or static automatic judgment. Manual judgment is time-consuming and labor-intensive, which not only delays the progress of product delivery, but also may lead to missed judgments and misjudgments. The so-called static automatic judgment is to control the test system to collect the data flow on the current bus after the operation of a certain inspection step, and automatically judge the correctness of all data at this collection time point. The judgment method described in "Test System", patent number: ZL201220652188.4. Although this kind of judgment improves the test efficiency to a certain extent, because it i...

Problems solved by technology

Although this kind of judgment improves the test efficiency to a certain extent, because it is only a judgment on a certain time point, if the data flow changes dynamically during an operation, it can only judge the correctness of the last shot of data, resulting in judgment Incomplete

Moreover, the operation of each simulator and exciter needs to be carried out manually at present. If the timing of the operation does not meet the requirements, or there is a little operation error, it will often cause the data to be automatically judged as wrong, which will affect the test.
