一种飞行器电缆插接状态自动化检测方法

An Automatic Detection Method for Plug-in State of Spacecraft Connectors

新一代飞行器的电气系统越来越复杂,依靠主观识别方法检测电缆插接状态,人工失误轻则烧毁星上设备,重则导致任务失败;提出一种飞行器电缆插接状态自动化检测方法,通过插接状态检测编码和信号变换设计,确保检测电路占用尽量少的电连接器资源和背板资源;通过信号走线优化设计,避免检测电路增加电缆分支数,降低电缆加工和敷设成本;通过电源走线优化设计,确保测试电路与星上电路隔离;文章方法无需飞行器加电即可自动检测电缆插错、漏插等问题,提高了飞行器综合测试的安全性和可靠性。

The new generation spacecraft electronics system becomes progressively complicated.Relying on subjective identification of plug-in states of spacecraft connectors,human error may lead to the burning of equipments and even mission failures.An automatic detection method is proposed,with advantages in utility-efficiency of connectors and backplane by a novel detection-transformer circuit,reduced cost of manufacture and assembly by harness routing optimization,and enhanced safety by isolating test circuit.The proposed method can detect the misinsertion,non-insertion and dislocation of harness connection before spacecraft powered on and thus improve the security and reliability of spacecraft testing.
