Description
Technical field
The utility model belongs to electric appliance energy-saving control field, and its control circuit directly can substitute hand switch, audio-switch, soft-touch control etc.Especially because not pulling out attaching plug after finishing using with electrical equipment, the security-related of standby energy consumption that power down source switch produces and electricity consumption facility is not related to.
Background technology
People need with switches such as manual, acoustic control, remote control or touches by electric power starting and closedown when using some appliance, as computer, printer, duplicating machine, televisor, air-conditioning etc.But conveniently people are often after using these appliance, do not remove the switch pulling out attaching plug or turn off on socket, the pilot lamp of these appliance point light yellow is allowed to be in the state of standby power consumption.Although there is major and minor spring hole scoket in the market, automatically the control circuit of alternating current is cut off by relay, control the power-off of secondary orifices position jack, but master control position does not still have power-off, although these products also can play the energy-conservation effect of a part, do not belong to the product of full power-off, if manually do not pull out attaching plug or turn off power switch, its master control position is still energized, and still can produce standby energy consumption, and therefore these electricity consumption facilities still also can bring the aging of components and parts and potential safety hazard because of energising.
Utility model content:
The purpose of this utility model will overcome above-mentioned defect exactly, after providing a kind of people to have left these electricity consumption facilities and be in again not using state or holding state time, completely automatically can cut off the energy-saving control circuit of alternating current.When human body enters into energy-saving control circuit induction range, sensor special detects the change of human body infrared spectrum, automatically switches on power.And learnt by the standby power point of switching power circuit to these electricity consumption facilities, and when meeting following two conditions: the detection of (1) sensor special is less than human body infrared spectrum, and namely people have left in the scope of infrared spectrum detection; (2) these electricity consumption facilities are in shutdown or holding state; At this moment energy-saving control circuit can cut off alternating current automatically, thus stops the waste of the energy, extends electrical equipment serviceable life.Be applicable to the use of computer, printer, duplicating machine, televisor, air-conditioning etc. appliance.Convenient and practical, energy-saving safe.The utility model by the following technical solutions for this reason.
Electric appliance energy-saving control circuit, comprise learning key SK1, 200VAC turns 5VDC Switching Power Supply, rpyroelectric infrared sensing circuit, MUC control circuit, power detection and sample circuit, signal amplification circuit, it is characterized in that: after described energy-saving control circuit energising, 220VAC step-down is DC5V by U1 (LNK364), power for giving the components and parts such as MCU and operational amplifier, then sampled by the current detecting of L3 current transformer and convert corresponding power to, through IC1 (LM358), signal is amplified, the signal produced when sensing human body with rpyroelectric infrared sensing circuit delivers to MCU together, judge that the current nobody of having exists, if any people at induction range, then MCU sends signal, relay adhesive is energized, if people leaves, MCU can have not in work by the automatic decision electrical equipment be connected on this product, as sampling come in power be greater than before learn into power, so no matter people with not all can not power-off, as this power be equal to or less than sampling come in power time, and people also have left, then power-off, to reach the object of economize on electricity, safety, environmental protection.When length is by three second of learning key, power detection be sampled to is delivered in MCU by signal amplification circuit and is preserved, as the contrast standard of standby power.
The principle of work of this energy-saving control circuit: after energising, uses switching power source chip LNK364, changes electric main 220VAC into 5VDC operating voltage, powers to the components and parts of this control circuit.When people enters induction range, human body in pyroelectric infrared sensor LHI878 automatic detection induction range, the signal sensed is passed to MCU control circuit by CRM7208 integrated circuit, MCU exports a signal again and makes normally opened relay adhesive, 220VAC conducting, can give peripheral load supplying by socket.If when peripheral load has high-power, such as computer is opened and is used, at this moment, energy-saving control circuit can realize intelligence control intelligence, the size of current electric current detected by current transformer and convert corresponding power to, by amplifying circuit, this signal is amplified to certain numerical value again, pass to MCU, the power that when confirming to press learning key three seconds, study comes is large or little, if current voltage is large, no matter whether people leaves, energy-saving control circuit all can not power-off, ensure the normal operation of computer, when current voltage is equal to or less than the voltage learning to come, such as shut down of computer, at this moment people left induction range after 5 minutes, MCU sends signal makes relay disconnect, 220VAC not conducting, peripheral load power down, people one enters induction range, this product can provide 220VAC again at once.
Advantage of the present utility model: full-automatic induction break-make electric main 220VAC power supply, when people enters induction range, this product can provide 220VAC automatically, when people leaves induction range, when load (such as computer) is not also opened, energy auto-breaking, realizes energy-conservation, safety, environmental protection object again.
