| Abstract: | Double-power supply automatic switch system requires high reliability and realtime. According to need of non-stop supplying, an intelligent optimized scheme of double-power supply automatic switch system is proposed with microcontroller P89c591 as main chip by sampling and comparing in this system. System permits users to have different settings according to distribution network and load conditions, to switch main power to reserve power according to different breakdowns. So the continuity of power supply is ensured by correct evaluation and fast switch of power source conditions. System hardware diagrams, software procedures and test results are provided in the paper. |
