Background
The camera load of most satellites in the remote sensing field generally works in a short period, and corresponding storage equipment is also in a short-term power-on working mode of the whole machine; the loads of space stations, skunks, marine satellites, telescopes and the like generally work for a long time, and corresponding storage equipment also works by electrifying the whole machine for a long time. With the development of the technology, the loads carried by the satellite are more and more, the working modes are different, and some short-term working such as optical cameras can be carried out; and some devices work for a long time, such as laser detection equipment, satellite platform data collection and the like.

s2, the satellite-borne storage device controller detects whether the satellite-borne storage device short-term module has a satellite-borne storage device short-term module work request provided internally, and if yes, the step S3 is carried out; if not, repeating the step S2;
s3, the satellite borne storage device controller detects whether the short-term module of the satellite borne storage device is in the power-on working state, if yes, the step S4 is carried out; if not, starting the power-on working state and performing the step S5;
s4, the satellite borne storage device controller detects whether the short-term module power-on working state of the satellite borne storage device is in the power-on process, if yes, the step S5 is executed after the power-on process is continuously completed; if not, performing step S5;
