航天箭载无线收发机遥测参数设计

Design of telemetry parameters for aerospace wireless transceiver

摘要:

箭载无线收发系统由于涉及的产品和环节较多,天线因属于结构件又不便于状态监测,导致故障定位的难度通常较大。若能在进行箭载无线收发机设计时就设置全面、合理的遥测参数,作为划清与外部设备接口界面的依据,则可为系统故障定位提供更多有力支撑。基于对历次飞行试验中因遥测参数设置不合理早成故障难以定位案例的研究,从利于故障定位的角度出发提出了箭载无线收发设备主要遥测参数设置项目及设置位置的建议。结合具体案例,分析了遥测参数设置不合理对故障定位造成的不良影响以及遥测参数改进设计的具体方法,供后续开展设计时参考。

Abstract:

It is usually difficult for fault locating of the aerospace wireless transceiver system, due to it involves so many products and the antenna are not convenient for state monitoring. With reasonable telemetry parameters setted in the design of aerospace wireless transceiver, the problem of fault location of wireless transceiver system can be solved by distinguishing the interface between the wireless transceiver and other devices. Based on case studies of difficulty in fault locating caused by unreasonable telemetry parameter setting in previous flight experiments, this paper puts forward some suggestions on setting the main telemetry parameters and positions of arrow-borne wireless transceiver from the perspective of facilitating fault location. Combined with a specific case, this paper analyzed the bad influence of unreasonable telemetry parameter setting on fault location and the specific method of improving telemetry parameter design for future design reference .
