The auto-control energy-saving switch

The utility model belongs to electronic technology field, is specifically related to a kind of automatic control apparatus switch.

" people Lai Dengliang; turn off the light when you leave " is the energy-conservation requirements of people to lighting circuit, also is the target that the electrical engineering technical staff pursues for many years, but for a long time, number has but expended a large amount of electric power in hundreds of millions altar lamp, makes the limited electric power resource of China not perform to due effect.The electric switch of lighting circuit is the basic electrical component of widespread usage in producing, living, and regular tap all is manual control, is difficult to avoid altar lamp, causes the waste of electric power.The auto-control energy-saving switch is a novel items in recent years, and all parts of the country are all being studied at present, but yet there are no shaped article so far.

The purpose of this utility model is the lighting circuit switch that a kind of stable, reliable, energy-conservation, automatic control will be provided.

The utility model adopts infrared sensor, receiver to do the input sensing element of switching circuit, with light-sensitive element control delay control circuit non-output signal on daytime, the controllable silicon that makes output control circuit is in turn-on and turn-off reliably at night, thus the on and off of control bulb.Circuit structure is: the D pin of infrared sensor SD04 connects dc power anode, the positive pole of S pin connecting resistance R1 one end and capacitor C 1, and the G pin connects the R1 other end and dc power cathode; The end of the negative pole connecting resistance R2 of C1 and the base stage of triode T1, another termination of R2 T1 collector electrode, an end of resistance R 3 and the positive pole of capacitor C 2, the emitter of T1 connects dc power cathode; Negative pole connecting resistance R4 one end of C2,6 pin of another termination integrated circuit (IC) of R4; The end of other end connecting resistance R5, the R6 of R3 and the positive pole of DC power supply, 8 pin of another termination IC of R5 and an end of receiver, another termination dc power cathode of receiver; 6 pin of another termination of R6 IC and capacitor C 3 one ends, another termination dc power cathode of C3; 1 pin of IC, 4 pin, 14 pin connect dc power anode, 12 pin, 13 pin are unsettled, 11 foot meridian capacitor C4 connect dc power cathode, 3 pin connect dc power cathode through C5,2 pin, 7 pin directly connect dc power cathode, cross-over connection potentiometer W between 1 pin, 2 pin, and 5 pin connect diode D1 anode, 9 pin connect diode D2 anode, 10 pin connecting resistance R7 one ends and light-sensitive element RG one end; Another termination dc power anode of R7, another termination dc power cathode of RG; The D1 negative electrode connects D2 negative electrode and bidirectional diode D3 one end, the control utmost point of another termination bidirectional triode thyristor of D3 SCR; Capacitor C 6 minus earths, positive pole connect dc power anode and diode D4 negative electrode, D4 anode connecting resistance R8 one end, capacitor C 7 one ends and voltage-stabiliser tube CZ negative electrode, CZ plus earth; Another termination of R8 C7 other end, can connect an end of silicon SCR one end and bulb; Another termination dc power cathode of SCR and fuse RD one end; Another termination AC power one utmost point of RD, another another utmost point of termination AC power of bulb.

The utility model circuit is simple, and element is few, and is with low cost, makes easily.Output circuit adopts the controllable silicon noncontacting switch, and power consumption is little, the life-span is long, and noiselessness, speed are fast.Adopting infrared sensor is the signal input element, and auxiliary light-operated with acoustic control, sensitive reliable, can realize the function of " people Lai Dengliang turns off the light when you leave " fully, its energy-saving effect highly significant.With the 60W bulb is example, and every lamp can economize on electricity about 200 degree/years.A large amount of auto-control energy-saving switches that adopt such as office, hotel, garden, corridor, benefit will be very huge.

Further specify structure of the present utility model and operation principle below in conjunction with drawings and embodiments.

Fig. 1 is circuit theory diagrams of the present utility model.

Input element of the present utility model adopts pyroelectric infrared sensor SD04 or SD02; Amplifying triode T1 requires the β value more than 200 times, also can adopt the amplifier integrated circuit; IC adopts the NE556 dual timer; Light-operated employing resistance in the dark 2M Ω, bright resistance are less than the photo resistance of 1K Ω; Electret condenser microphone is adopted in acoustic control.Infrared sensor is combined with Fresnel Lenses, can improve signal and accept sensitivity, enlarges switch monitoring distance and angle.When the people comes into monitoring range, experience the faint infrared energy that human body distributes by SD04, and it is converted to the signal of telecommunication, be coupled to T1 by C1, T1 is amplified to signal about 75dB, passes to NE556 by C2, R4, and NE556 can control by two-way, two-way output, thus can satisfy the function of acoustic control, light-operated, human body sensing.Adjust the time constant that W can change circuit, delay time 10 seconds adjustable by 45 seconds.By the control utmost point of D1, D2 output control signal, play control action to bidirectional triode thyristor.Daytime, at the state of quitting work, night, the RG resistance increased by photo resistance RG control entire circuit, and 10 pin of NE556 are high level, open control circuit, make autocontrol switch work.
