Abstract
The utility model relates to an energy-saving device, in particular to an LED (light-emitting diode) energy-saving control device for an office. The LED energy-saving control device comprises a human body induction trigger module, a photosensitive trigger module, a central processing unit and a power driver module. The output signals of the human body induction trigger module and the photosensitive trigger module are output and connected with the power driver module through the control of the central processing unit. A human body signal and a light signal are respectively collected by the human body induction trigger module and the photosensitive trigger module in the device. When people work at the office, lighting equipment is automatically turned on in darker light; when people are not in the office during the setup time, the lighting equipment is turned off; and when people go back to the office, the lighting equipment is automatically turned on so as to achieve the purpose of intelligent energy-saving control.
Description
Technical field
The utility model relates to a kind of energy saver, particularly be a kind of LED office energy-saving control device.
Background technology
Office need manually open electric consumption on lighting equipment when light is dark by day.But people often forgot and turn off the light when light brightened, or office long-time nobody the time, electric consumption on lighting equipment is also lighted, and so just wastes very much electric energy.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of LED office energy-saving control device is provided.
The technical scheme that its technical problem that solves the utility model adopts is: LED office energy-saving control device, comprise human body sensing trigger module, photosensitive trigger module, central processing unit and electric power driving module, described human body sensing trigger module is connected electric power driving module with the output signal of photosensitive trigger module through central processing unit control output.
Described human body sensing trigger module connects infrared sensor IC2 by the output of induced electricity pole piece TX, connects the pierce circuit of being made up of triode Q2, switching tube Q1 and peripheral circuit thereof by infrared sensor IC2 output again and constitutes.
Described infrared sensor IC2 adopts the RD627 transducer.
Described photosensitive trigger module is made of photo resistance LDR output connection resistance R 4, resistance R 5, resistor R P, capacitor C4, triode Q3.
Described central processing unit is the 89S51 single-chip microcomputer.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: this device adopts human body sensing trigger module and photosensitive trigger module to gather human body signal and light signal respectively, when people in when office, the more moving electric consumption on lighting equipment of lighting of light, when people close electric consumption on lighting equipment at the time out of office of setting, when people get back to office again, just open electric consumption on lighting equipment automatically, reach the purpose of intelligent power saving control.
Description of drawings
Fig. 1 is a frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, LED of the present utility model office energy-saving control device, comprise human body sensing trigger module 1, photosensitive trigger module 2, central processing unit 3 and electric power driving module 5, described human body sensing trigger module 1 is connected electric power driving module 5 with the output signal of photosensitive trigger module 2 through central processing unit 3 control outputs.
Described human body sensing trigger module 1 connects RD627 infrared sensor IC2 by the output of induced electricity pole piece TX, connect by triode Q2 by RD627 infrared sensor IC2 output again, the pierce circuit that switching tube Q1 and peripheral circuit thereof are formed constitutes, right as human body near induced electricity pole piece TX, the oscillator oscillatory work, emitter outputting oscillation signal from switching tube Q1, this oscillator signal is through semiconductor diode D rectification, make triode Q2 conducting, the 2nd pin of RD627 infrared sensor IC2 becomes low level by high level, the 6th pin of RD627 infrared sensor IC2 becomes high level by low level, the collector potential of triode Q2 also is input to the 34th pin I/O end of 89S51 single-chip microcomputer IC1 for high potential at this moment, after 89S51 single-chip microcomputer IC1 internal processes is judged, by its 3rd pin output high level, through resistance R 6 current limlitings, triode Q4 is conducting thereupon also, the relay J adhesive, its contact J-1 connects the electric consumption on lighting device power supply (DPS), for office provides illumination by transferring normally closed point normal battle to.
As people during from office, induced electricity pole piece TX, switching tube Q1 and triode Q2 all are in cut-off state, and the 6th pin of RD627 infrared sensor IC2 is a low level, the collector potential of triode Q2 also is an electronegative potential, its signal is after 89S51 single-chip microcomputer IC1 inside is provided with time-delay, and the low level of being exported by its 3rd pin is ended triode Q4, and relay J discharges, its contact J-1 transfers normal battle to by normally closed point, cut off the electric consumption on lighting device power supply (DPS), turn-off the office lighting power consumption equipment, reach energy-conservation purpose.
Described photosensitive trigger module 2 connects resistance R 4 by photo resistance LDR output, resistance R 5, resistor R P, capacitor C4, triode Q3 constitutes, when not sensing illumination, photo resistance LDR is high-impedance state, triode Q 3 ends, the 28th pin I/O end that is input to single-chip microcomputer IC1 also is low level state, after single-chip microcomputer I C1 internal processes is judged, by its 3rd pin output high level, through resistance R 6 current limlitings, triode Q4 is conducting thereupon also, the relay J adhesive, its contact J-1 connects the electric consumption on lighting device power supply (DPS), for office provides illumination by transferring normally closed point normal battle to.Reach automation control, energy-conserving and environment-protective.
After photo resistance LDR is by irradiate light, be converted to the low resistive state below 30 Ω immediately, triode Q3 obtains the biasing conducting, the 28th pin I/O end that this signal is input to single-chip microcomputer IC1 is high level state, after single-chip microcomputer IC1 internal processes is judged, by its 3rd pin output low level, triode Q4 is ended, relay J discharges, and its contact J-1 transfers normal battle to by normally closed point, cuts off the electric consumption on lighting device power supply (DPS), turn-off the office lighting power consumption equipment, reach energy-conservation purpose.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
