针对卫星导航抗干扰射频单板人工测试过程较复杂且难以快速批量测试的问题,提出了基于C#与STM32的卫星导航抗干扰射频单板自动化测试系统。首先,通过自动化测试软件与STM32主控制器数据通信控制射频开关电路进行数据采集,然后将采集数据与多次人工测试结果对比分析,形成多项校准参数并应用于测试系统,最后通过批量测试验证系统测试结果准确性。通过批量试验数据证明各项测量指标误差均小于2.5%,测试效率较人工测试提升至少3.3倍,具有较高测量精度和效率。同时,该自动化测试系统对测试单板有过压过流保护功能,能有效保护被测单板不被损坏,综合整体性能具有良好的应用前景。

Aiming at the problem that the manual test process of satellite navigation anti-interference RF Board is complex and difficult to test in batches efficiently,an automatic test system for satellite navigation anti-interference RF Board based on C#and STM32 is proposed.Firstly,through the automatic test software,the equipment communicates with the STM32 main controller to control the RF switch circuit for data acquisition.Then,the collected data is compared and analyzed with multiple manual test results to form a number of calibration parameters and is applied to the test system.Finally,the accuracy of the system test results is verified by batch test.Through batch test data,it is proved that the error of each measurement index is less than 2.5%,and the test efficiency is at least 3.3 times higher than that of manual test,with high measurement accuracy and efficiency.At the same time,the automatic test system has overvoltage and overcurrent protection for the test board.It can effectively protect the tested board from damage,and has a good application prospect in terms of its overall performance.
