CIRCUIT FOR GENERATING ARTIFICIAL SATELLITE SEPARATION SIGNAL OF HIGH RELIABILITY ARTIFICIAL SATELLITE

摘要

PURPOSE: An artificial satellite separation signal output circuit for a high reliability artificial satellite is provided to improve the reliability in launching the artificial satellite or separating, and to minimize the failure rate by operating a backup computer stably against wrong operation of a main processor with detecting the stable separation signal. CONSTITUTION: An artificial satellite separation signal generating and detecting circuit is composed of a separation signal command circuit(10) applying a separation command signal to a separation signal generating circuit(30) in separating; the separation signal generating circuit detecting the separation signal from the separation signal command circuit and generating a pulse signal for driving a separation timer(40); the separation timer generating a time-out signal in not stopping the separation timer by a main processor(50); and a power switching relay(60) of the artificial satellite processor converting power from the main processor to an artificial satellite backup processor(51) in generating the time-out signal. The reliability is improved by operating the backup computer stably against wrong operation of the main processor.
