background technology:
there is multiple illumination energy-saving controller in the market, for the Lighting control of public arena, part energy-saving controller does not consider the needs of some application of special occasions, as PPT is play in meeting-place or classroom, intensity of illumination of drawing the curtain together is more weak, now, also should close lighting, ensure the project effect of PPT; Partial illumination energy-saving controller light fixture controls too sensitive, and illuminating lamp switch exchange frequency is higher, is unfavorable for the useful life of light fixture; The cost of partial illumination energy-saving controller is higher, and power consumption is high, and cost performance is to be improved.
summary of the invention:
the object of this invention is to provide a kind of room lighting energy-saving control device and energy-saving control method.
above-mentioned object is realized by following technical scheme:
a kind of room lighting energy-saving control device, its composition comprises: governor circuit, described governor circuit connects and is connected with light testing circuit, number testing circuit, lamp control circuit, display circuit, warning circuit, manual switch circuit respectively, described governor circuit comprises power circuit, clock circuit, reset circuit, described number testing circuit comprises 2 infrared sensors, and the infrared sensor described in 2 is all connected with described governor circuit.
described room lighting energy-saving control device, described power circuit adopts ac buck rectifying and voltage-stabilizing again, by 220V alternating voltage first through transformer pressure-reducing, then through bridge rectifier rectification, the last voltage being obtained+5V by integrated stable voltage circuit 7805 voltage stabilizing, is connected with single-chip microcomputer 40 pin Vcc.
described room lighting energy-saving control device, described clock circuit adopts internal oscillator mode, system crystal oscillator is 12MHz, two terminals of crystal oscillator respectively with the 18(XTAL2 of Singlechip clock pin) with 19(XTAL1) be connected, and get starting of oscillation electric capacity and be respectively 30pF.
described room lighting energy-saving control device, described reset circuit adopts the mode of electrification reset and button reset compound, and reset circuit exports and puts single-chip microcomputer No. 9 RST pins.
an energy-saving control method for room lighting energy-saving control device described in claim 1-4, the method comprises the steps:
when there being people to appear at indoor, PT exports corresponding voltage pulse signal, amplifies output signal enter window voltage comparator through UC; Potentiometer RW2 determines a window voltage interval, lower than this voltage range, then exports as low level; Higher than this voltage range, then export as high level; Or the output of door 74HC32 is connected with the P1.1 of AT89S52 single-chip microcomputer; RW1 adjusts multiplication factor; Rheostat RW2 for setting the threshold level of window, the sensitivity of the adjustable detection amplifying circuit of RW1 and RW2; When indoor unmanned turnover, pyroelectric infrared sensor makes dielectric absorption electric charge due to equalized temperature, signal is not almost had to export, namely output is directly that power supply exports, therefore UC output voltage is greater than V1(VB-) time, UB exports high level, and UC output voltage is less than V2(A+) time, UA exports high level, and warp or door export high level;
when there being people to pass in and out, the dielectric temperature of transducer changes, and surface release electric charge, will produce the in-phase input end that atomic weak AC signal directly delivers to amplifier, signal is defeated after one-level is amplified
go out, UA and UB constitutes voltage comparator; When UC output voltage amplitude is between V1 (VB-) and V2 (VA+), UB and UA holds output low level, warp or behind the door output low level.Therefore, by single-chip microcomputer P1.1 pin condition adjudgement, whether people passes in and out;
in order to calculate indoor number, arrange the number testing circuit that two structures are identical, one of them number testing circuit is placed in side, doorframe outer, and output signal delivers to the P1.1 pin of single-chip microcomputer; Another number testing circuit is placed in doorframe Inner along side, and output signal delivers to the P1.2 pin of single-chip microcomputer; When P1.1 and P1.2 keeps high level, unmanned turnover is described, occupancy is constant; When P1.1 and P1.2 occurs that trailing edge indicates that people passes in and out, if prior to the trailing edge of P1.2, the trailing edge of P1.1 occurs that explanation has people to enter, then occupancy adds 1, otherwise illustrate that someone goes out, then occupancy subtracts 1, thus determines occupancy;
when indoor light undercapacity being detected and indoor have during people and all drive electromagnetic relay to open indoor lamp by single-chip microcomputer P2.0, P2.1 and P2.2 pin; When bright and clear in sensing chamber, no matter whether indoor have is closed lighting per capita.
beneficial effect:
light testing circuit of the present invention adopts photo resistance to realize in conjunction with A/D conversion.Photo resistance stable performance, the life-span is long, price is low, although the response time comparatively photodiode and phototriode long, considering that native system is not high to the requirement of real-time response, in order to improve cost performance, adopting photo resistance to realize.When not having incident light, inner electron-hole pair is by compound, and the resistance of photo resistance is also just larger.After the metal electrode at photo resistance two ends has added voltage, electric current is wherein just had to pass through, when it is subject to the light irradiation of specific wavelength, electron-hole pair will drift about, electric current will become large along with the enhancing of illumination, thus realize opto-electronic conversion, namely illumination is stronger, and the resistance of photo resistance is less.Bright resistance exports as analog quantity, in order to be translated into the digital quantity that single-chip microcomputer can identify, adopting ADC0809 to realize analog/digital conversion, and exporting eight railway digital amounts the P3 mouth of single-chip microcomputer to.
the present invention can intensity of illumination in real time in sensing chamber and number, has people and insufficient light is turned on light, and does not bright and clearly turn on light, confirm indoor nobody turn off the light, accomplish that people walks lamp and puts out, reduce the waste of unnecessary electric energy.Control the quantity of turning on light according to occupancy, reduce the wasting of resources that the few bright light of people causes more, easy for installation, cost performance is high.
