摘要
无人机数据链是无人机与地面控制终端进行信息传输和交换的综合通信系统，数据链系统的性能直接影响到无人机的整体性能，因此针对数据链系统，研究开发集数据测量、信号处理、数据库、专家系统为一体的智能化自动测试系统具有重要的理论价值和实际意义。
本文从应用需求的角度，主要论述了无人机数据链自动测试系统的组建及系统部分功能的实现。
文章首先对无人机测控系统及自动测试系统做了简要的说明，并重点介绍了GPIB标准总线接口模式。同时，文章对自动测试系统的组建及相关测试方法进行了介绍。在深入研究无人机数据链的综合性能和相关测试技术的基础上，结合GPIB总线提出了无人机数据链自动测试系统的硬件组建方案。该系统软件结构设计采用面向对象的模块化设计思想，在Visual C++开发环境下实现本测试系统的部分软件功能，完全能够满足系统测试的要求。
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.
