Spaceborne equipment isolation and security system

Abstract

A spaceborne equipment isolation and guarantee system relates to the field of electrical isolation of spaceborne equipment on satellites, and solves the problems that a power supply and a data link in existing spaceborne equipment are correlated with each other, the noise interference can be easily introduced, the reliability between communication units is poor, the system performance is further affected, and the like. The spaceborne equipment isolation and guarantee system comprises a power supply energy transmission and control system and a ZigBee wireless data transmission system, wherein a solar cell array supplies power to the power supply energy transmission and control system; the power supply energy transmission and control system distributes power to the spaceborne equipment through a QI wireless energy transmission technology, the spaceborne equipment is connected with a spaceborne center computer through a ZigBee wireless data transmission technology, and the spaceborne center computer is communicated with the power supply energy transmission and control system through a CAN bus. According to the spaceborne equipment isolation and guarantee system disclosed by the invention, each spaceborne equipment is a truly independent unit and does not have a direct electrical connection with other equipment, and thus the spaceborne equipment is completely in an electrical isolation state with other equipment, and the stability and reliability of the system can be improved.

Description

technical field [0001] The invention relates to the field of electrical isolation of space-borne equipment on satellites, in particular to a space-borne equipment isolation and guarantee system; complete electrical isolation between space-borne equipment is realized by adopting ZigBee technology, QI wireless energy transmission technology and power supply control technology. Background technique [0002] The equipment carried inside the satellite needs the power supply system to supply power to it. This process is managed and distributed by the power controller. From the overall path of the power supply line, it can be seen that all the equipment equipped on the satellite is related to each other in terms of power supply. To achieve isolation between components, it is easy to introduce noise interference, and at the same time, if there is a high-power device running, it will easily cause voltage fluctuations, interference, etc., which will affect the overall performance; in t...
