Embodiment Construction

[0040] The present invention will be further described below in conjunction with accompanying drawing.

[0041] A satellite load power supply backup system, including a control command relay, a power supply module, a control module and a load relay; the control command relay is two magnetic latching relays connected in parallel; the control command relay is controlled by an external satellite control system, To determine whether to start the subsystem; the input end of the control command relay is connected to an external power supply (that is, the primary power supply provided by the satellite platform to the load subsystem), and the output end of the control command relay is divided into two paths, one of which is connected to the input end of the power module , the other is connected to the input terminal of the control module; the power module is connected to the external load through the load relay, the power module adopts the cold standby mode, and the cold standby mode i...

Abstract

The invention relates to a backup system, particularly relates to a satellite load power supply backup system, and aims to solve the technical problems that the backup unreasonably occupies limited instruction resources and communication bandwidths or is poor in reliability in the prior art and provide a satellite load power supply backup system. The system comprises a control instruction relay,a power supply module, a control module and a load relay, wherein the input end of the control instruction relay is connected with an external power supply, and the output end of the control instruction relay is divided into two paths, one path is connected with the power supply module, and the other path is connected with the control module; the power supply module is connected with the load relay; the power supply module adopts a cold standby mode; the control module comprises a direct-current converter warm standby assembly and a control panel cold standby assembly, the control panel cold standby assembly is used for communicating with an external satellite service control system and an external load, one path of the control panel cold standby assembly comprises a first relay and a first control panel which are sequentially connected in series, and the other path of the control panel cold standby assembly comprises a second relay and a second control panel which are sequentially connected in series.

Description

technical field [0001] The invention relates to a backup system, in particular to a satellite load power backup system. Background technique [0002] With the continuous development of the aerospace industry, more and more satellites are being launched, and the satellite launch density is getting higher and higher. The research and development cycle of satellite platforms and new loads is getting shorter and shorter, because the power supply of the load subsystem on the satellite platform has no backup or the backup is unreasonable. Unreasonable backup means that the power supply of the control part and the load part are not separated and the control board has no backup. The power supply of the control part and the load part are not separated, and the star control system needs to judge the working status of the cold standby power board. When the power board is in an abnormal working status, switching to backup requires more control commands, occupying limited command resourc...
