Embodiment Construction

[0039] In the embodiment of the present invention, the autonomous satellite power supply control circuit based on satellite-rocket separation can switch on or off the path of the power supply unit supplying power to the satellite according to the relative positional relationship between the satellite and the launch vehicle, thereby realizing power supply control to the satellite. At the same time, before the satellite is separated from the launch vehicle, the power supply path of the power supply unit to the satellite can be disconnected, so as to reduce the energy consumption during the process of the launch vehicle carrying the satellite and save the power of the power supply unit.

[0040] The basic structure of the satellite autonomous power supply control circuit based on satellite-rocket separation provided by the embodiment of the present invention is as follows: figure 1 As shown, the circuit includes: a power supply unit 110 , a first control unit 120 , a second contro...

Abstract

The invention discloses an independent satellite power supply control circuit based on star-launch vehicle separation. The circuit is composed of a power supply unit, a first control unit, a second control unit and a gating unit. The power supply unit is used for providing power for a satellite by the gating unit; the first control unit connected with the second control unit is used for forming afirst signal according to a relative position relationship between a satellite and a launch vehicle; the second control unit connected with the gating unit and the first control unit is used for forming a second signal based on the first signal and providing the second signal for the gating unit; and the gating unit connected with the power supply unit and the second control unit is used for connection or disconnection between the gating unit and the power supply unit based on the second signal.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a satellite autonomous power supply control circuit based on satellite-rocket separation. Background technique [0002] With the rapid development of micro-satellite technology and the popularization of satellite commercialization, there are more and more mission requirements for one satellite with multiple satellites or multiple devices carried by satellites, and the requirements for satellites are becoming more and more stringent. [0003] However, a large amount of energy will be consumed when the launch vehicle carries the satellite, and missions such as multi-satellite missions consume even more energy, which is very unfavorable for the launch of satellites. Contents of the invention [0004] In order to solve the existing technical problems, the embodiment of the present invention mainly provides a satellite autonomous power supply control circuit based on satellite-r...
