Force signal is as control signal control housed device work.
In the prior art, during power line carrier, PLC, the high-frequency controling signal that power line carries can be to the electric of housed device
Element impacts, and reduces the reliability of electrical equipment, so as to reduce the service life of housed device.During present invention application,
First on power line loading frequency be more than 20kHz control signal, control signal is arranged to 20kHz so that control signal and
Electric power signal more easily discriminates；Then high frequency transformation, the high frequency transformer are carried out by high frequency transformer to multi-carrier telecommunication number
Including high voltage second coil and low-voltage secondary coil, the turn ratio of high voltage second coil and low-voltage secondary coil is 9：1, due to control
The voltage of signal processed is typically unsuitable too high, so as to be 9 by the turn ratio of high voltage second coil and low-voltage secondary coil：1 so that use
Voltage ratio between piezoelectric voltage and control signal voltage is 9：1；Bandpass filtering subsequently is carried out to high voltage second coil；To low pressure
Secondary coil carries out high-pass filtering, and cut-off frequency uses 10~15kHz, passes through bandpass filtering so that the electricity that high voltage second coil comes out
Power not belt controling signal, and pass through high-pass filtering so that the control signal that low-voltage secondary coil comes out is done by electric power signal
Disturb smaller；Subsequently the electric power signal after bandpass filtering is powered to housed device；Using the electric power signal after high-pass filtering as
Control signal control housed device work, so as to avoid the electrical equipment that high-frequency controling signal is directly entered housed device, and
It is only used as control signal and plays control action, improves the reliability of electrical equipment, and improve the service life of housed device.
Further, the turn ratio of the primary coil of the high frequency transformer and high voltage second coil is 1：1.
Further, the common iron core of high voltage second coil and the low-voltage secondary coil.
Further, step S4 also includes following sub-step：Electric power signal after high-pass filtering after analog-to-digital conversion by controlling
Housed device work processed.
Further, the passband of the bandpass filtering uses 35~65Hz.
The present invention compared with prior art, has the following advantages and advantages：
The home intelligence method that the present invention is realized based on PLC technology, avoids high-frequency controling signal and is directly entered
The electrical equipment of housed device, and be only used as control signal and play control action, the reliability of electrical equipment is improved, and improve
The service life of housed device.
Embodiment
