A multi-level redundant adaptive bus transfer power distribution method and system

Abstract

The application discloses a kind of multi-level redundancy adaptive bus switching power distribution method and system, system includes: multi-level redundancy bus, at least include main bus and standby bus;Solid-state switching unit array, including multiple solid-state power switches, each solid-state power switch is connected between multi-level redundancy bus and on-board load;And control unit, control unit is integrated with memory, control unit output fault level determination result;Field programmable gate array FPGA is connected with solid-state switching unit array, and is configured to control the on-off of each solid-state power switch according to fault level determination result and preset load importance classification, on-board load is dynamically switched to corresponding bus in multi-level redundancy bus and is powered on supply.The fault is divided into three levels, which provides basis for differentiated switching strategy;And, based on load importance classification strategy: in combination with load importance and fault level, the optimal switching path is dynamically selected, rather than fixed main standby switching.
