Abstract:The avionics system integrated automatic test equipment has good general-purpose performance, which is extremely beneficial for improving the maintenance guarantee efficiency of aircraft electronic equipment. However, the degree of informationization of the test require its supporting client software for human-computer interaction. In the powerful visual programming environment of MFC Microsoft framework library, this paper calls the test program running environment component and ACCESS database through COM, ActiveX and other interface technologies to compile a human-machine session-friendly client software to implement test program management, test report management, user rights management, test log management and other functions. After being verified, the client software runs stably and can cooperate with the operators to control various instruments of the automatic test equipment platform to complete the test task and manage various information during the test.
