[embodiment]
Consult Fig. 1, household power carrier theft-proof warning system, at the register one's residence output terminal serial connection trap 1 of place's voltameter of family's indoor power grid, respectively and be connected to power carrier detector 2, power carrier receiving host machine 3, interlock module 4, the signal that described trap 1 stops power carrier detector 2 and power carrier receiving host machine 3 to send enters city's electrical network on family's indoor power grid; Power carrier detector 2 detecting intrusion signals, and sending into family's indoor power grid after the invasion signal Processing; The signal that power carrier receiving host machine 3 is collected on family's indoor power grid, and will export demonstration after the signal Processing and carry out alarm, described power carrier receiving host machine 3 sends the interlock information to interlock module 4.On family expenses (220v illumination) electrical network, realize setting up warning system, each equipment of system is connected with electrical network by supply socket, various data are transmitted on line of electric force, transmit and receive various data on the line of electric force by coupled circuit, each equipment is realized the function of each equipment by self decode system, processing and control element (PCE).
Consult Fig. 2,2 pairs of invasions of described power carrier detector Signal Processing comprises carries out the intelligent data analysis to the invasion signal, the invasion signal that analysis obtains is encoded, and coded signal amplifies, enters family's indoor power grid through coupling unit by modulation, electric current.Described power carrier detector 2 comprises sensor, comparator circuit, intellectual analysis processor, amplifying circuit, coding circuit, modulation circuit, the coupled circuit that connects successively.Described sensor comprises at least a in infrared sensor, microwave remote sensor, vibration transducer, the smoke transducer.
