Abstract

The invention relates to a fault automatic detection and repair power supply selection control circuit, and belongs to the field of power supply control. The fault automatic detection and repair power supply selection control circuit is mainly composed of a voltage transformation module, an isolation voltage module, a photoelectric coupling module, a single-chip microcomputer control module and a relay enabling module, and has the characteristics of multi-channel intelligent control, automatic fault detection and repair, stability, reliability, real-time performance, high efficiency, energy conservation, environmental protection and the like which are incomparable with the conventional power supply control circuit; and intelligent power supply and distribution control can be satisfied.

Description

technical field [0001] The invention belongs to the field of power supply control, and in particular relates to a fault automatic detection and repair power supply selection control circuit. Background technique [0002] With the rapid development of information technology, many power consumption systems have continuously improved requirements for power supply control circuits, especially when the power consumption system is unattended on site, higher requirements are put forward for the power supply and distribution system to provide continuous, stable and reliable services . [0003] Therefore, it is urgent to design a fault automatic detection and repair power supply selection control circuit. During the power supply process, the power system can automatically and intelligently select the power supply, especially when the mains or diesel generators stop supplying power during use. The battery is used as the power input, and can automatically detect and repair the failure...
