Its course of work is:

1. when normal alternating current is imported, overpressure protector 4 is failure to actuate, rechargeable battery power supply 3 is powered to pulse generator 8 through electric field induction switch 6, under the effect of pulse generator 8, make triode 9 conducting intermittently, promptly intermittently to infrared remote receiver 7 power supplies and carry out the stand-by operation at intermittence, after remote controller is sent infrared signal, after infrared remote receiver 7 receives processing, triode 10 conductings (this moment two-color diode 11 show the ruddiness of flicker but the time very of short duration), through optical coupler 12 to change-over circuit 13-1 pin power supply with import infrared signal into, and then the 13-2 pin of change-over circuit is through resistance, high level of diode 22 feedbacks is given pulse generator 8, then make triode 9 no longer be subjected to the control of pulse generator this moment and power to infrared remote receiver constantly, simultaneously, the 13-8 pin of change-over circuit has also been sent to high level to the base stage of triode 15 through diode 24, triode 15 conductings, under the emergency service of energy storage capacitor 14, relay 16 adhesives, connect alternating current and lead to television power circuit 20, make it produce 5V, the 12V power supply: (this moment two-color diode 11 show that the orange-colored light of flicker represent that alternating current delivers in the television set), the 5V power supply makes microprocessor 19 work that resets immediately; The 12V power supply has substituted the power supply of 14 pairs of relays of energy storage capacitor immediately, and to capacitor 14 chargings, uses in order to start next time.Meanwhile, the infrared signal that remote controller is sent is received by the microprocessor in the television set 19, after treatment, as the infrared signal of sending is the start code signal of this machine, microprocessor CPU just feeds back a high level (CPU that also has is a low level) immediately and gives change-over circuit, after change-over circuit is handled, this high level is given triode 15 again, form the self-insurance conducting, this high level also is sent to the Switching Power Supply of television set simultaneously, like this, television set just begins operate as normal (the stable green glow of two-color diode 11 demonstrations this moment is represented television set operate as normal).

After the television set operate as normal, controllable silicon conducting in the change-over circuit, having cut off after start has enabling signal to lead to the passage of triode 15 again, simultaneously, change-over circuit 13-3 pin send a high level to go to make the electric field induction switch to quit work, send a high level to give pulse generator, the high level that diode 22 feedbacks are come becomes low level, make triode 9 can not get pulse signal and stop power supply infrared remote receiver, quit work and have a rest thereupon infrared remote receiver, in addition ,+12V replenishes to chargeable battery through diode 26.

2. after the shutdown infrared signal that remote controller is sent, microprocessor just send a low level to remove change-over circuit immediately, and triode 15 is ended immediately, relay 16 discharges immediately, alternating current disconnects immediately fully, and like this, rechargeable battery power supply 3 is powered to pulse generator through the electric field induction switch again.The 8-5 pin that while change-over circuit 13-3 pin also send a low level to remove pulse generator, effective through the high level that the 13-2 of change-over circuit pin feedback is come like this, the base stage of triode 9 becomes low level and continues conducting.This just make infrared remote receiver with this moment the shutdown infrared signal received through optical coupler 12 to commentaries on classics. the controllable silicon that changes in the circuit is reinforced power supply.The conducting because the controllable silicon in the change-over circuit just has been triggered when television set is started working, in the blink of shutdown, controllable silicon still is in conducting state, at this moment again through the coupler 12 timely power supplys that must send here, so just make controllable silicon just along with the length and short synchronous conducting of shutdown infrared signal time, make the infrared signal of sending here through photoelectrical coupler can't arrive the base stage of triode 15, thereby (at this moment 11 of two-color diodes show the ruddiness that glimmer to have avoided the unnecessary power circuit that alternating current is led to television set, expression is shut down this moment), after the shutdown infrared signal stops, the ruddiness of two-color diode 11 also disappears, change-over circuit quits work, do not have ability to send signal to each point, the infrared remote receiver in this electricity-saving appliance begins standby intermittently again.

3. television set is in operate as normal, if after meeting electrical network power failure suddenly, the microprocessor of some model can restore automatically and be holding state, the processor of some model has memory function and can not restore automatically and be holding state, and this just removes to order about power control terminal in the microprocessor by the photoelectrical coupler in change-over circuit and the change-over circuit 12 and restores automatically and be holding state.As with the shared infrared remote receiver of television set, the 13-6 pin of change-over circuit can be connected with the CPU19-1 pin and connect diode 27 and get final product.

4. under television set operate as normal or holding state, if mains supply system zero main line disconnects voltage is raise suddenly, this overpressure protector can disconnect the AC power of input immediately, makes television set protected.This overpressure protector can also be used in single-phase socket, socket, single-phase circuit breaker and the unidirectional leakage switch and go.

This electricity-saving appliance is mainly developed and is designed for television set manufacturer, just because can make like this in all prior stand-by energy-savingization (this electricity-saving appliance also can be used in the television set that is using) of the television set of producing.

This electricity-saving appliance can produce immeasurable energy-saving effect, if all need the electrical equipment of remote control standby all to adopt this energy-conservation technology, it will produce considerable social benefit and economic benefit.
