Abstract

The invention discloses a 1553B wireless communication system oriented to space solar power plants, belonging to the technical field of wireless communication. The system includes the central main control computer, measurement and control subsystem, data transmission subsystem, power management and distribution subsystem, microwave wireless energy transmission subsystem, attitude and orbit control subsystem and thermal control subsystem. The subsystems are all equipped with wireless service node units; the wireless service node units include radio frequency signal transceiver modules, conditioning modules, baseband signal processing modules, processor modules and memory modules; in the process of remote control and telemetry, the wireless service node units are used to realize 1553B message Mutual conversion with wireless messages, in which the remote control telemetry information is transmitted between subsystems through the wireless bus. The system is suitable for space solar power plants.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a wireless bus communication system for space solar power plants. Background technique [0002] Space Solar Power System (SSPS) is a power system that converts solar energy into electrical energy in space, and then transmits it to the ground for use on the ground by other means. The establishment of space solar power plants aims to use solar energy in space to provide GW-level power for the ground, and the construction, operation, and management of space solar power plants are very ambitious projects. [0003] Like most spacecraft, space solar power plants also have various subsystems according to their functions. According to the functions of the subsystems, they may be divided into solar energy collection and conversion subsystems, power transmission and distribution subsystems, and microwave wireless energy transmission. Subsystem, structure subsyst...
