Charging system and method of carrying spacecraft

Abstract

The invention discloses a charging system and method of a carrying spacecraft. The system comprises a power supply unit, a pressure pneumatic switch and a time delay control unit which are arranged on the carrying spacecraft, wherein the power supply unit is connected to a power consumption load arranged on the carrying spacecraft and used for supplying power to the power consumption load; the pressure pneumatic switch is used for detecting external pressure of the carrying spacecraft, and the time delay control unit is started when the external pressure is reduced to a preset threshold value. According to the charging system and the method of the carrying spacecraft, the external pressure variation of the carrying spacecraft is detected, power supply of the power consumption load of the carrying spacecraft is controlled by the aid of time delay control and with an automatic charging method, the reliability of power supply of the carrying spacecraft is improved, the method can be complementary with an existing passive charging method, automatic charging is started for the spacecraft when passive charging fails, and the spacecraft can be ensured to continue to complete a follow-up task.

Description

technical field [0001] The invention relates to the field of spacecraft control, in particular, to a system and method for powering up a spacecraft. Background technique [0002] For the spacecraft launched on board, it is generally required that no power is applied during the launch process, that is, the power supply of the spacecraft is controlled by the delivery system. For the spacecraft that needs to be separated, after the separation switch detects the separation state, the spacecraft is automatically powered on; for the non-separated spacecraft, the carrier system needs to give a power-on control signal to power the spacecraft. [0003] In the separation power-on method, generally 1 to 2 separation switches are arranged on the separation surface of the spacecraft and the delivery system, and are in a compressed state before separation. When the carrier system sends out the satellite-rocket separation control signal to control the explosive bolt or the pyrotechnic cut...
