Detection device based on intelligent household power supply circuit

The invention discloses a detection device based on an intelligent household power supply circuit, and relates to the field of safety protection of an intelligent household, for the purposes of solving the technical problems of incapability of detecting abnormal power sources in intelligent household lines, incapability of distinguishing malicious invasive power failure from large-scale regional power failure, incapability of facilitating escape of residents in case of disasters, lack of feedback control and effective communication, untimely startup of backup power sources and the like by use of conventional intelligent household safety protection equipment. The structure provided by the invention is characterized by comprising a central control early warning module which is used for examining effective values of commercial power and receives the commercial power; a zero-crossing detection unit which is used for examining the frequency of the commercial power, receives the commercial power and outputs detection signals; an identifying module which receives the detection signals and outputs identifying signals to the central control early warning module; and a flat display which carries out information interaction with the central control early warning module. The detection device provided by the invention is applied to electricity abnormity early warning of an intelligent household system.
