Abstract: A feed switcher for a satellite telecommunication system includes a microcontroller, a first relay, and a second relay. The first relay receives as inputs a first satellite feed and a second satellite feed. The second relay receives as inputs a third satellite feed and an output of the first relay. The output of the first relay includes the first satellite feed or the second satellite feed. The microcontroller has a first port and a second port, and the output of the second relay is based on whether at least one of the first port and the second port is open. Therefore, the output of the second relay may be either the output of the first relay or the third satellite feed.

Abstract translation: 用于卫星电信系统的馈电切换器包括微控制器，第一继电器和第二继电器。 第一个继电器接收第一卫星馈送和第二卫星馈送作为输入。 第二继电器接收第一卫星馈送和第一继电器的输出作为输入。 第一继电器的输出包括第一卫星馈送或第二卫星馈送。 微控制器具有第一端口和第二端口，并且第二继电器的输出基于第一端口和第二端口中的至少一个是否打开。 因此，第二继电器的输出可以是第一继电器或第三卫星馈送的输出。
