The voltage of control signal 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
Voltage ratio between utilization voltage and control signal voltage is 9：1；The electric signal that bandpass filter is exported to high voltage second coil
Carrying out bandpass filtering, electric signal that high-pass filter export to low-voltage secondary coil carries out high-pass filtering, cut-off frequency uses 10~
15kHz；Pass through bandpass filtering so that the electric power that high voltage second coil comes out not belt controling signal, and pass through high-pass filtering so that
The control signal that low-voltage secondary coil comes out is smaller by the interference of electric power signal；Control module believes the electric power after high-pass filtering
Number as control signal control housed device work, so as to avoid the electric member that high-frequency controling signal is directly entered housed device
Part, and be only used as control signal and play control action, the reliability of electrical equipment is improved, and improve the use longevity of housed device
Life.
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, control module is additionally operable to the electric power signal after high-pass filtering by controlling family expenses to set after analog-to-digital conversion
Standby work.
Further, the passband of the bandpass filtering uses 35~65Hz.
The present invention compared with prior art, has the following advantages and advantages：
A kind of system controlled in real time housed device of the present invention puts, it is to avoid high-frequency controling signal is directly entered house
With the electrical equipment of equipment, and it is only used as control signal and plays control action, improves the reliability of electrical equipment, and improve house
With the service life of equipment.
