The invention relates to a dual-power-supply switching system and satellite vehicle-mounted equipment. The system is characterized in that when a control unit receives a control instruction of an upper computer and needs to transmit a signal, the control unit sends an enabling turn-on instruction to turn on a first power supply assembly and turn off a second power supply assembly at the same time; when the signal needs to be received, the control unit sends an enabling turn-on instruction to turn on the second power supply assembly and turn off the first power supply assembly at the same time, so that alternate work of the signal transmitting circuit and the signal receiving circuit is realized. According to the technical scheme provided by the invention, deployment is simple, the operation is convenient, manual monitoring is not needed, the labor investment is reduced, the problem of misoperation caused by manual operation is avoided, reliability is higher, the user experience degree is good, and the satisfaction degree is high.

    本发明涉及一种双电源切换系统及一种卫星车载设备,该系统当控制单元收到上位机的控制指令,需要信号发射时,控制单元发使能打开指令打开第一电源组件,同时,关闭第二电源组件;需要信号接收时,控制单元发使能打开指令打开第二电源组件,同时,关闭第一电源组件,从而实现了信号发射电路和信号接收电路的交替工作。本发明提供的技术方案,部署简单、操作便捷,由于无需人工监控,减少了人工投入,同时避免了人工操作带来的误操作的问题、可靠性更高,用户体验度好、满意度高。
