| As the communication system between unmanned aerial vehicle (UAV) and the ground control terminal (GCT), the performance of UAV data link affects the whole work of UAV. And it is highly necessary to study on the approaches to realize automatic test, which combines the techniques of data measurement, signal processing, database and expert system, on data link system.In this thesis, a solution of UAV data link automatic test system (ATS) is presented and part of the design is completed.The principle of telemeter and telecontrol system of UAV and ATS is explained for the first point, and meanwhile the general purpose interface bus (GPIB) is discussed in detail. At the same time, the thesis introduces the organization of ATS and some relative test method. With in depth research on all the characters of data link, a solution of this test system is presented based on GPIB. And with the application of object oriented (OO) design method, the software of this test system is developed with Visual C++, which is one of the most efficiency developing environment nowadays, and the test result can meet the request of test totally. |
