Abstract
A double-power-source intelligent management system relates to a double-power-source switching system and solves the problems of poor sensitiveness and low reliability of an existing double-power-source switching system. The double-power-source intelligent management system comprises a processor, a main power source, a standby power source, a first detecting module, a second detecting module, a charging module, a switching circuit, an over-current protecting circuit and an output circuit, wherein the main power source and the standby power source finish charging and discharging by the aid of the processor and sufficiently realize intelligent switching. When the main power source has electricity, the standby power source is in the state to be detected. When supplying power, the main power source can be controlled by the processor if the standby power source is under voltage, and the standby power source is fully charged by the aid of the charging module and immediately works once the main power source powers down. The double-power-source intelligent management system is applicable to a double-power-source switching system with high requirements on power source stability.
