Satellite payload task management system

Abstract

The invention discloses a satellite payload task management system. The satellite payload task management system comprises a data management computer, a data bus, a battery, a distributor, a payload, a data storage multiplexer and a satellite-ground telemetry and remote control processing unit. Through adoption of the satellite payload task management system, integral task management of functions such as power supply and distribution, telemetry and remote control, and health management of a satellite-borne payload by a satellite can be realized.

Description

technical field [0001] The invention relates to the field of space satellite payload task management, in particular to a satellite payload task management system. Background technique [0002] In the prior art, the management of satellite payload tasks is usually completed by the cooperation of the data management subsystem, measurement and control communication subsystem, power supply and power distribution subsystem. Management and control functions such as key timing action commands; the measurement and control communication subsystem realizes the collection and transmission of satellite payload telemetry data and digital transmission data; the power supply and power distribution subsystem realizes the power supply of satellite payloads and converts them into corresponding voltage amplitudes. Secondary distribution voltage. With the rapid development of satellite technology, the number and types of payloads carried by satellites are increasing, and the requirements for s...

AI Technical Summary

Problems solved by technology

With the rapid development of satellite technology, the number and types of payloads carried by satellites are increasing, and the requirements for satellite payload task management are also different. Satellite payload task management implemented by multiple subsystems is not conducive to satellite integration. The information flow interaction is more complicated, the interfaces are diverse and come from different stand-alone machines, the software design is not optimized enough, and the weight and power consumption of the whole star are increased, so it is urgent to improve the design

[0003] At present, the interface for satellite payload management is usually in the form of an input-output one-to-one interface, which has low reliability. If the interface channel fails, the satellite payload will not work normally.

[0004] In addition, in the prior art, the health management of satellites mostly adopts single-level fault monitoring methods such as status monitoring and abnormal alarm. Requires high cost and resources for health management implementation
