A kind of independent power-on circuit for star-arrow separation

Abstract

The embodiment of the present invention discloses a star-and-arrow separation autonomous power-on circuit, including a solar cell array, a bus bar, a battery pack, a self-starting power-on switch, a separate self-starting circuit, a separation switch, a discharge switch, a star computer and a DC / DC module, before the separation of the satellite and the rocket, the separation self-starting circuit is set to the enable state, the separation switch is set to the closed state, the discharge switch is set to the open state, and the whole star is in the power-off state. After the satellite and the rocket are separated, the separation switch is closed. The status changes to the disconnected state, the self-starting power-on switch is turned on, the battery pack supplies power to the bus, and the whole star is powered on to start. Send the connection command to turn on the discharge switch, and set the separated self-starting circuit from the enabled state to the prohibited state, the separated self-starting circuit controls the self-starting power-on switch to be disconnected, and the battery pack supplies power to the bus through the discharge switch, realizing satellite in-satellite Autonomous power-up after arrow separation.

Description

technical field [0001] The invention relates to the technical field of star-arrow separation, in particular to an autonomous power-on circuit for star-arrow separation. Background technique [0002] The traditional satellite platform is generally in the power-on state during the launch process. After the satellite and rocket are separated, the star affairs computer detects the effective signal of the satellite and rocket separation. As the initial moment of the whole satellite, it starts to execute the program control program, starts the attitude control, and the pyrotechnics detonation control. , status monitoring, load photography and other operations. However, with the rapid development of micro-satellite technology and the rapid development of commercial spaceflight, the demand for multi-satellite or satellite-carried missions is increasing day by day. If the satellites are always powered on when they are on the rocket, it may cause unnecessary damage to the main star. ...

Problems solved by technology

However, with the rapid development of micro-satellite technology and the rapid development of commercial spaceflight, the demand for multi-satellite or satellite-carried missions is increasing day by day. If the satellites are always powered on when they are on the rocket, it may cause unnecessary damage to the main star. Signal interference, and this design idea is not flexible, and the satellite battery needs to be recharged before the launch, which cannot meet the needs of rapid commercial space launches.
