航空电子设备自动测试系统的软件架构设计

Software Architecture Design of Automatic Test System for Avionics

为检测和定位航空电子设备的故障,研究并设计了一种自动测试系统的软件架构;该架构包含了测试软件和测试数据库,测试数据库存储有测试被测设备的相关数据,测试软件将其作为输入,通过自动测试设备输送给被测设备,最终测试软件接收被测设备的输出并将其与测试数据库的预期数据相比较得出测试的结果;测试软件由手动测试模块、自动测试模块、系统自检测模块、测试记录读取和测试结果记录模块4个功能模块组成,自动测试和手动测试可以自由切换;该系统不仅能使用自动测试功能仿真被测设备的飞行环境,还可以使用手动测试功能具体定位分析故障,降低了设备的维护成本,缩短了维修时间。

To detect and locate fault of Aviation Electronic System,research and design a kind of software architecture of automatic test system.Software architecture includes test software and test database.Related data is stored in the test databases,will be putted into the tested equipment by test software.Test software receives the output of the test device and compares it with the expected results of the test database.Eventually it will get the test results.Test software is composed of four functional modules：manual testing module,automatic test module,system self checking module,test record reading and test result record module.Automatic test and manual test can be free to switch.This system not only can use the automatic test function to simulate the flight environment of the equipment,but also can use the manual test function to analyze the fault,reduce the maintenance cost and shorten the maintenance time.
