Abstract

The invention provides a method for realizing modularized plug-and-play of a satellite power control and distribution unit, belonging to the field of a satellite power supply system, and solving the problems that the research period of an existing satellite power supply system power control and distribution unit is long and the satellite task requirements cannot be rapidly responded to. According to the device, a lower computer and N extended function modules are assembled and integrated by a back plate; the lower computer and the N extended function modules realize data transmission through an inner bus circuit; the inner bus circuit comprises an inner bus main interface circuit, a module enabling coding simulation channel gating circuit and N inner bus sub-interface circuits; the inner bus main interface circuit is mounted in the lower computer; the module enabling coding simulation channel gating circuit is mounted in the back plate; each extended function module is internally provided with the inner bus sub-interface circuit; the inner bus sub-interface circuits are connected with all the inner bus sub-interface circuits through the module enabling coding simulation channel gating circuit. The method provided by the invention is applicable to modularized extension and rapid integration of the power control and distribution unit.

Description

technical field [0001] The invention belongs to the field of satellite power supply system. Background technique [0002] Since the U.S. Department of Defense formally submitted a report on the development of the "Space Rapid Response Operations" (ORS) program to the Congressional Defense Committee in April 2007, all countries have devoted themselves to researching satellites with rapid response capabilities. The rapid integration capability of each subsystem of the satellite is the prerequisite for the rapid integration, rapid application and rapid response of the satellite. As one of the most important satellite subsystems, the satellite power supply subsystem provides safe and reliable power guarantee for the normal operation of other satellite subsystems and payloads. It is mainly composed of battery packs, solar arrays, and power control and distribution units. At present, battery packs and solar cell arrays are formed by series-parallel connection of commercialized mo...
