The. Ate8000 Automatic Test System Master Software Design And Implementation,

With the growing complication of modem control system and electronics, Automatic Test Equipment (ATE) has become the necessary main equipment during the producing and testing of electronics. Also due to the high requirement for accurateness, complication and assurance of air-borne avionics equipment, the maintenance and failure-diagnoses of aviation electronics system are definitely supported greatly by ATE. This engineering project comes from the requirement of Xi抋n Aircraft Industry (Group) Company Ltd. Its avionics center asked for a ATE station, whose first test object is Flight Management Computer (FMC). So we develop ATE8000, the synthesized automatic test system. Firstly this dissertation described the development, composition and structure model of an Automatic Test System, compare and discuss the bus technology, and studied the test methods and the UUT (Unit Under Test) -- FMC. From them, we put forward of design our solution of ATE8000, especially the requirement and demand of its software. Emphasizing on the software design, this dissertation expatiates on the thinking thread of designing the main control software of ATE8000, including: how to design the software structure; how to divide the programming; how to schedule the test, how to design the user interface; how to design the communication interface and how to design each model. The implementation of the software is represented by detail flow charts. At last, based on the design, the programming of main control software is realized via a special programming tool? Lab Windows/C VI. Cooperating with responding hardware, this main control software will complete the synthesized functions and performance test of FMC according to the test manual specification. The test runs automatic, and the test results can be got and displayed. Any failure of UUT can be detected and localized to the exact electrical board.
