Abstract

본 발명은 위성 송신 시스템의 이중화 제어 스위치 장치에 관한 것으로, 특히 위성 송신 시스템의 이중화 구현에 있어 이중화 제어 스위치의 신뢰성을 향상시키도록 한 위성 송신 시스템의 이중화 제어 스위치 장치에 관한 것이다. 높은 신뢰성을 요구하는 위성 송신 시스템에서 신호 경로를 구성하는 장비들이 아무리 신뢰성이 높아도 종래 위성 송신 시스템의 이중화 제어 스위치 장치의 전체 가용도는 이중화 제어 스위치의 가용도보다 낮아서 이중화 제어스위치의 가용도에 너무 의존적이며, 이중화 제어 스위치에서 에러가 발생되면 신호를 절체할 수 없게 되는 문제점이 있었다. 본 발명에 따른 위성 송신 시스템의 이중화 제어 스위치 장치의 전체 가용도는 제1이중화 제어스위치의 가용도와 제2이중화 제어 스위치의 가용도로 분할되어 의존하므로서, 이 장치의 전체 가용도는 향상되고 두 개의 이중화 제어 스위치 중 한 개만 정상 동작을 하면 신호의 절체가 가능하며 중단없이 신호원을 위성으로 전달할 수가 있다.The present invention relates to a redundant control switch device of a satellite transmission system, and more particularly, to a redundant control switch device of a satellite transmission system to improve the reliability of the redundant control switch in the redundant implementation of the satellite transmission system. No matter how reliable the equipments that make up the signal path in a satellite transmission system requiring high reliability, the overall availability of the redundant control switch device of the conventional satellite transmission system is lower than the availability of the redundant control switch, which is too much for the availability of the redundant control switch. It is dependent and there is a problem that the signal cannot be switched when an error occurs in the redundant control switch. Since the overall availability of the redundant control switch device of the satellite transmission system according to the present invention is divided and depends on the availability of the first redundant control switch and the availability of the second redundant control switch, the overall availability of the device is improved and two redundant If only one of the control switches is in normal operation, the signal can be switched and the signal source can be delivered to the satellite without interruption.
