Remote command output method and system for satellite load isolation and passive matching

Abstract

A load isolation and passive match remote control command output method and system for satellite, comprises two sets of first module combinations having identical structures, second module combination, first module combination, the second module combines the remote control commands respectively sent by the isolated excitation source, the current of the remote control command is amplified and sentto the first load respectively, second load, The first module combination, the second module combination parallel, the first load, the second load parallel through the switch, the first group of module combination series with the first load, the second group of module combination series with the second load, if the first load and the second load are the same type of load, the switch is short-circuited, if the first load and the second load are different type of load, the switch is turned off.

Description

technical field [0001] The invention relates to a remote control command output method and system for satellite load isolation and passive matching. Background technique [0002] The satellite remote control command is a discrete command drive signal from the satellite platform remote control output device to each remote control command user. Because the excitation source of the direct command source of some satellite remote control output devices is generally 10-12V positive pulse and milliampere-level drive capability, but At present, the load relays used by remote command users generally require a maximum drive current of 200mA. If the remote control output device directly sends the direct command excitation source, direct command power supply and return line to the user, it is generally required that the remote control command user is not allowed to communicate with other power sources of its own. total land. Therefore, only relying on the excitation source with milliam...

AI Technical Summary

Problems solved by technology

This way to achieve a single direct remote control command output with a drive capability greater than 300mA and a redundant design requires several triode 3DK9D, which occupies too much equipment area under the demand of a large number of direct commands

At the same time, sometimes a direct command is needed to drive different types of load relays at the remote control command user end to meet the needs of different equipment development, and different types of load relays are generally not allowed to be used in parallel
