摘　　要：为了提高地面测控系统自检的测试效率,提出并实现了一种基于并行测试技术的系统信号回环自检测试方法。将地面测控系统的所有对外接口信号通过回环测试电缆接入到系统内部的故障诊断计算机上,在对所有接口信号进行分析、归类的基础上,利用故障诊断计算机现有硬件资源,有针对性地提出了信号自检测试方法,并设计了基于并行测试技术的系统自检测试软件。实际测试结果表明,基于并行测试技术的系统自检所需时长远小于采用串行测试方案所需时长,测试效率得到显著提升。In order to improve the self-checking efficiency for the ground test and control system(GTCS),a loop-back self-checking method of system,signals based on parallel testing technology is proposed and implemented.All the interface signals are connected to the fault diagnosis computer(FDC)in the GTCS through loop-back test cable.Based on the analysis and classification of all interface signals and the existing hardware resources of FDC,the self-checking method is proposed and the self-checking software based on parallel testing technology is designed.The actual test results show that the total time of system self-checking based on parallel testing technology is far less than serial test scheme,and the test efficiency is significantly improved.
