Voltage stabilizing value of the charging voltage less than voltage-stabiliser tube VD1, voltage-stabiliser tube VD1 cut-offs, controllable silicon SCR 1 does not open control, power on.
When the electrical appliance of master control output end do not start or shut down it is standby be stopped, the electric appliance work(of master control output end
When rate is less than setting value, electron watt-hour meter is used for the intermittent time of the optocoupler output CK1 and CK2 output count pulses tested
Elongated, system power supply, to electric capacity C1 charging time delays, makes the charging voltage of electric capacity C1 more than the voltage stabilizing of voltage-stabiliser tube VD1 through resistance R1
Value, voltage-stabiliser tube VD1 conductings, controllable silicon SCR 1 is turned on, and relay obtains electric adhesive, and tape relay switch release, power supply is all off.
Electric capacity C1, resistance R1 are the adjustment element of delay time so that during master control electrical equipment normal work, electron watt-hour meter
The optocoupler output interval ON time that count pulse is used to test is less than its delay time, and master control electrical equipment does not start or closes
Machine is standby when being stopped, and optocoupler output interval ON time is much larger than its time delayed turn-off time.During power remove, diode
D5 provides leakage path for the charging voltage of delay capacitor C1, is that circuit is again started up preparing.
When pressing tape relay and switching, i.e. hand off power supply.
Start:
Tape relay switch is pressed, power on, the controlled electrical equipment of master control enters normal operating conditions.And some television sets are needed
Secondary start can be just carried out by the power key of remote control again, launch into normal operating conditions.
Shutdown:
A:Tape relay switch is pressed again, is cut off the electricity supply.
B:Shut-off master control electrical equipment, master control electrical equipment is stopped, and through electric circuit inspection, cuts off the electricity supply.
C:Master control electrical equipment completion work, into holding state, through electric circuit inspection, cuts off the electricity supply.
D:After computer enters program shutdown, through electric circuit inspection, cut off the electricity supply.
E:Make master control electric appliance standby with remote control, or into holding state after setting television set turning device to sleep mode, through Energy Saving Control
Electric circuit inspection, control tape relay switch release, dump.
Use rule:TV is seen in bedroom, and without the machine of switching off the TV of getting up, shut down top box, seems during cold day more convenient, before falling asleep,
As RTV remote television sets sleep timing 30 minutes, television set enters holding state after 30 minutes, through electric circuit inspection, cuts off the electricity supply,
I.e. the power supply of shut-off television set simultaneously, together with controlled peripheral hardware electrical equipment, such as Set Top Box, the power supply such as DVB also controlled pass
Disconnected, this controller power source is simultaneously turned off, zero-power energy-conservation, memorandum.
Household electrical appliances energy-saving controller, the shutdown of master control electrical equipment or work completion enter holding state, power of the output less than setting
When, Energy Saving Control is carried out, serial equipment power supply time delay is all off, zero-power energy-conservation.A machine is controlled, shut-off is all.It is adapted to
Single electrical equipment or multiple correlation electric appliance series are used.Using the circuit of electronic electric energy meter, it is adapted to the load detecting of various performances, essence
Really reliable, control circuit power consumption is low, and element is few, low cost, convenient and practical, energy-saving safe, and save trouble memorandum.
