Design And Realization Of Integrate Automatic Test Equipment Of Some Plane’s Flight Control System

The automatic test technology, is a comprehensive application of technology, the technology includes computer,control theory, information science, mathematics, electronics and so on, is the embodiment of multidisciplinaryknowledge combination, from a certain extent, it reflects a country’s level of industrial. Automatic test equipmentand with automatic test technology including computer control, data acquisition device, data storage device, data processing equipment, and related equipment connection etc.. Automatic test equipment using automatic testing technology, the control program has been compiled, can be automatic or manual participation of small analyte test,which will greatly improve the work efficiency and testing accuracy, safety and so on. Automatic test equipment in this paper the main object is the maintenance of aircraft electrical and electronic equipment, the equipment testing and fault location etc..This paper is based on the aircraft flight control system, aiming at the above problems, the use of automatic test technology, combining hardware with software, developed an automatic test equipment for the user, to solve the user’s needs. The main contents:1, R & D set up automatic test platform. The framework of test platform is composed of a plurality of independentearthquake reinforcement box structure, platform equipment were installed in the assembled box, all equipments are connected by cable related. In the platform, the use of a large number of GPIB equipment, VXI equipment andnon-standard equipment, to meet the testing needs, effectively complete the test task.2, design and manufacture of supporting interface adapter. Because the type of equipment to test equipment ismore complicated, perplexing signal adapter will be specially designed, to test equipment connected with the automatic test platform, the realization process of the equipment to be tested from the incentive to signal acquisition. Interface adapter, in accordance with the standards of design and manufacture, the test platform of the resources needed to introduce the interface adapter front panel, convenient use of tested equipment. And the interface adapter can be well installed on the testing platform, and can be easily removed, which provides favorable conditions for us to do various tests.3 test program, developed the equipment under test(TP). In the test, each of the tested equipment resources required, test methods are different, the need to write different test procedures corresponding to different needs.Research and development of testing procedures for the use, is a key step of the automatic test, it will make the whole testing according to the desired results run smoothly, to save time and effort to.4, research and development of automatic test equipment self checking function. The self-test for power on self-test and self maintenance detection, power on self-test is completed every time the system boot, can also choose to perform in the system menu, maintenance of self detection is mainly in the use of certain period after theexecution or when the system fails to discharge at.The automatic test equipment and good feedback in the user, many products, fault location for users, make the product get timely repair, guarantee the flight safety.
