A distributed intelligent power supply and distribution system of a spacecraft

Abstract

The invention relates to a distributed intelligent power supply and distribution system of a spacecraft, which is composed of a pulse battery, a functional battery, a plurality of intelligent power distribution centers in different regions, a main control device and a ground power source. The pulse battery is used for the power supply of the spacecraft, including initiating explosive devices, solenoid valves, equipment heating and motor power supply. The functional battery is used in the power supply of the spacecraft, including control, measurement and so on. Intelligent distribution centersare distributed by region on spacecraft and interconnected by standard buses. The intelligent distribution center receives the bus command from the main control equipment, completes the on-off controlof the power supply of each load on the spacecraft, and realizes the intelligent cut-off protection of short circuit and overcurrent of each load. The invention solves the shortcomings of the traditional spacecraft electromagnetic power supply and distribution system, such as large volume, heavy weight, low integration and intelligence, and has the characteristics of good digitalization, intelligence, integration and universality.

AI Technical Summary

Benefits of technology

This patented technology solves problems associated with previous systems by providing more efficient power supplies for spaceships while reducing costs compared to older designs. It also includes an integrated solution that combines both analog and digital signals into one signal without requiring long wires or complicated cabling arrangements. Additionally, it suggests breaking up the original design of the communication path used during data transfer from central controlling devices (CUs), making them easier to integrate within existing circuits instead of relying solely upon external sources like electricity. Overall, this new approach provides better performance and efficiency than previously possible.

Problems solved by technology

This patented technical problem addressed in this patents describes how current methods have limitations such as complexity interfaces, lacking digitality, insufficient energy usage efficiency due to limited space allocation capabilities, poor overall performance, excessive hardware costs, etc., making it difficult to integrate into an advanced avionics (A/S)-based electric aircraft platform's future needs.
