Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
As shown in figure 1, this zero-power soft-touch control modular circuit is used for electronic product, using button switch and soft-touch control
The switch of electrical appliance is opened and closed, under electrical equipment closed mode, institute's electrical appliance Zero-power-consumption standby is reached.
5 pin are connected on the power supply+5V power supplys of institute's electrical appliance first, 6 pin connect the CPU controlling switches machine letter of institute's electrical appliance
Number control end, using low level as starting-up signal.3 pin and 4 pin of IC2 optocouplers are connect to the switching on and shutting down control end of controlled electrical equipment simultaneously
On, 1 pin is connect into 220V power supply energization inputs, 7 pin are connect to one end of the 220V supply inputs of institute's control apparatus, 220V power supplys connect
After logical, 1 pin L ends 220V voltages are divided into two-way, are powered all the way to the pin of VT1 bidirectional triode thyristors 1, another road is through C1 capacitance connections to bridge
Formula commutation diode a, through C1 capacitance decompressions, bridge rectifier diode a rectifications, VD1 voltage-regulator diode voltage stabilizings, after C2 capacitor filterings
9V voltages are exported to power to IC1 optocouplers and IC2 optocoupler internal illumination pipes.
When going to touch P touch points with hand, Q1 triodes sense static electricity on human body's voltage, turn on Q1, and Q1 colelctor electrodes are defeated
Go out low level, be that IC1 optocouplers and IC2 optocoupler internal illuminations pipe are luminous, photo resistance receives IC1 internal illumination pipes inside IC1
It is luminous to be irradiated in photo resistance, make the very little that photo resistance becomes inside IC1,220V voltages are through R1 resistance, through IC1 optocouplers
Internal photosensitive resistive touch hair VT1 bidirectional triode thyristors triggering pin, makes VT1 bidirectional triode thyristors obtain electric triggering and conducting, 3 pin output 220V electricity
Electric power supply is controlled in pressure supply, while the luminous tube inside IC2 optocouplers is luminous, the photo resistance inside IC2 is become very
It is small, controlled electric appliance is detected start output signal, controlled electric appliance is in open state；While the CPU computers of controlled electric appliance
Circuit control start output signal is controlled, the internal illumination pipe of the pin of IC1 optocouplers 5,6 pin is kept as electricity condition；When P touch points without
After human body touch, Q1 triodes are by the LED3 luminous tubes inside LED2 luminous tubes and IC2 optocouplers inside IC1 optocouplers are because losing
Electricity is without lighting, and it is very big that IC2 optocoupler internal resistances resistance becomes, and controlled electrical equipment is realized that a starting-up signal terminates.
LED2 luminous tubes dead electricity inside IC1 does not light and is, but the LED1 luminous tubes inside IC1 optocouplers obtain electric holding hair
Photo resistance still very little inside light state, IC1 optocouplers, VT1 bidirectional triode thyristors are tended to remain on, and institute's control electrical equipment is kept
Energization working condition.When needing to close in controlled electrical equipment, then touch in P touch points, Q1 triode ONs, IC1 optocouplers
Portion's luminous tube and IC2 optocoupler internal illumination pipes obtain the photo resistance very little that resistance becomes again inside electroluminescence, IC2 optocouplers, work as institute
When controlling electrical equipment in open state, institute's control electric switch machine signal end is received after off signal, institute's control electrical equipment cpu control circuit
The pin of LED1 luminous tubes 6 inside IC1 optocouplers is in high level, LED1 luminous tubes inside IC1 is not lighted；When P points are touched without human body
After touching, because Q1 triodes are by IC1, IC2 optocoupler internal illumination pipe do not light, and photo resistance becomes very inside IC1 optocouplers
Greatly, 220V voltages can not pass through, and IC1 optocouplers tend to remain on VT1 bidirectional triode thyristors, and VT1 bidirectional triode thyristors are by 3 pin
Without 220V voltage outputs, appliance cut-off is controlled, Zero-power-consumption standby, using electricity wisely is reached.
This circuit because C1, C2 and C3 capacitance very little, and be no own loss again, this modular circuit itself is also at
Zero-power-consumption standby state.
