Chapter 30 Defects Analysis and Strategy Seeking of Automatic Test and Diagnosis System (ATDS) for Airborne Equipment

摘要

First of all the paper describes the typical hardware structure and software platform of automatic test and diagnosis system (ATDS) for airborne equipment, analyzes main defects of ATDS which includes concentrated 19-inch rack plus single operation site not convenience to maintenance, momentary test not help to monitor the whole operating status, the confidence of test data, the problem of microwave parameters test, the choice of test path either through the unit connector or the test point on PCB, the progress of chip and data bus confuse the ATDS, and then describes the strategy and progress tendency of the future ATDS such as multi-data buses fusion ATDS, distributional ATDS and network ATDS, major synthetic ATDS, and portable ATDS.
