Problems solved by technology
[0003] At present, 1553B and CAN buses are mostly used for information communication between the various components of the launch vehicle electrical system. The functions of each device are relatively single, the degree of integration is not high, and the cost of the existing bus is high, which is not conducive to commercial application.

The invention discloses a carrier rocket electrical system and a data processing method. The carrier rocket electrical system comprises a rocket upper level, a rocket second level and a rocket first level. The rocket upper level electrical system comprises a first power supply board card, a first centralized interface, a first FPGA board card, a radio frequency channel board card, a CPU calculation and storage module and an information sensitive module. The first power supply board card is used for providing unified power supply in the rocket upper stage; The first centralized interface is used for providing a unified interface in an upper stage of the rocket; The first FPGA board card is used for processing data; And the radio frequency channel board card is used for processing radio frequency channel information in an upper stage of the rocket. The beneficial effects of the invention are that the rocket bodies of all parts of the carrier rocket electrical system are supplied with power in a centralized manner; The integration level and reliability of an electric system on a rocket are remarkably improved through centralized modes such as centralized interface and centralized dataprocessing, meanwhile, the weight of components and equipment for rocket installation of the system is remarkably reduced through integration, and the rocket transport capacity is remarkably improved.
Description
technical field [0001] The present disclosure generally relates to the technical field of rocket electrical systems, and specifically relates to a launch vehicle electrical system and a data processing method.
