See also Fig. 3.Control circuit comprises: power supply 21, control section 22, detection rating unit 23 and stimulus part 24.Power unit 21 inputs are connected with input power supply 3 by power line (plug) 5, and its output is connected with control section 22; The output of control section 22 is connected with accessory power outlet 4; The input that detects rating unit 23 is connected with the output of accessory power outlet 4, and its output is connected with the input of control section 22 inputs and stimulus part 24 respectively; The output of stimulus part 24 is connected with the input of control section 22.
See also Fig. 4.Power unit is made of power transformer (9V/1VA) B1, bridge rectifier Z, piezo-resistance R15, voltage-stabiliser tube V1 and electric capacity E1, C1; Wherein: the input of power transformer B1 and meet piezo-resistance R15 after be connected with electric network source, its output is connected with bridge rectifier Z, the output of bridge rectifier Z also meets electric capacity E1, C1,1,2 pin of voltage-stabiliser tube V1 connect both ends of power respectively, and its output is connected with the input of back level control section.
Control section is made of relay J DQ, resistance R 1 and transistor Q1; Wherein: the coil of relay J DQ is connected with the collector electrode of power supply with transistor Q1 respectively, and the normally opened contact K-1 of relay J DQ is connected with output plug, and the base stage of transistor Q1 is connected with the input that the back level detects rating unit by resistance R 1.
Detecting rating unit is made of integrated circuit U1 (for example model LM324), resistance R 2, R3, R4, R5, R6, R7, R8, R9, R10, R13, R16, R17, light-emitting diode L1, diode D1, D3, D6, capacitor C 2, E3, E4; Wherein: serial connection two resistance R 2, R3 between 14 pin of integrated circuit U1,10 pin, the intermediate connection point of this two resistance R 2, R3 is connected with 12 pin of integrated circuit U1,4 pin of integrated circuit U1 are connected with the output of the voltage-stabiliser tube V1 of power unit, and be connected with 2 pin of back level stimulus part triode Q2, between 14 pin of integrated circuit U1 and 7 pin, be connected in series a light-emitting diode L1.

The power-on pulse that the utility model energy-saving controller needs is provided by trigger with the shutdown pulse, it shake the remote signal that control directly is controlled by household electrical appliance, energy-saving controller is just started shooting receiving infrared signal.When electrical equipment was return holding state, energy-saving controller was by the current detection circuit electric network source that loses contact with reality automatically, and the task that wait for this moment is born by energy-saving controller, at this moment wait for the transformer power consumption that power consumption depends on energy-saving controller.Press the remote controller energy-saving controller again and be opened simultaneously that electrical equipment enters holding state, electrical equipment is opened fully when pressing for the second time.
When pressing arbitrary button on the electric appliance remote controller, because Q2 inside is made up of photosensitive two diodes and a highly sensitive reception amplifier and a demodulator that has compensate function, the signal of output is given the back level as TTL and cmos compatible signal, D2 and E2 have the issuable interference of other circuit of the inhibition of work, this moment, Q2 was output as end level, therefore 14 pin of U1 are high level, because 7 pin are low level, light-emitting diode L1 green light is bright, this moment household electrical appliance for example television set be in holding state, therefore the voltage that flows through very low 3 pin of load current of resistance R 11 is lower than 2 pin voltages, by comparator 1 pin output low level, compare 7 pin output low levels by next comparator again, 8 pin output this moment high level, charging by electric capacity E2,13 pin voltages slowly raise, 12 seconds have been spent～16 seconds, by another comparator 14 pin output low levels,, pass through R11 if when input load is light, D4, the 1 pin output low level of D5 current detecting U1 (LM324) disconnects relay coil, thereby cuts off out-put supply, output indicator does not work, and this moment, television set was in stand-by state.Wait for the no-load power consumption that power consumption is almost transformer, just can save the energy greatly if the design of the no-load power consumption of transformer is very low.
Press the arbitrary key of infrared transmitter (household electrical appliance remote controller), be low level by the output signal that infrared receiver detects this moment, comparison by U1 (LM324), make 14 pin output high level, green light is bright, thereby make output insert electrical network again, for the second time pressing electrical equipment (for example television set) is opened fully, the load current that flow through resistance this moment is big, and therefore the voltage of 3 pin is high level, compares 7 pin output high level by two utmost point comparators again, green light is constant, 8 pin and 13 pin all are low level, and it is constant that keep 14 pin voltages this moment, and household electrical appliance (for example television set) enter operating state.
