Description
Technical field
The present invention relates to a kind of the variation and control the control device that color lamp is bright or go out by the photo resistance value.
Background technology
Present common various monolithic processor controlled street lamp or color lamp, lighting hours is short mostly, does not meet the seasonal variations rule.Such as light-operated lamp, both wasted energy later on also in illumination 12 of nights, easily form light pollution again, the controller that has, though energy-conservation, lighting hours is obviously short in the time of in the winter time, as according to bright time-delay 5 hours, just turn off the light later on at 9 in evening, bring very big inconvenience for the pedestrian at night.
Summary of the invention
The present invention seeks to overcoming the deficiency of above-mentioned prior art, provide a kind of not only energy-conservation, but also can provide the energy-conserving and environment-protective color lamp controller of adequate illumination time to the people of nocturnalism in Various Seasonal.
The present invention includes capacitor step-down voltage stabilizing circuit, stable oscillating circuit, starting high level reset circuit, regularly closed circuit for lamp, comparative voltage circuit, relieving circuit; The capacitor step-down voltage stabilizing circuit includes resistance R 1, R2, capacitor C 1, C2, diode D1, D2 and voltage stabilizing didoe VDZ; The 220V alternating current is through resistance R 1, R2 current limliting, and the VDZ voltage stabilizing is passed through in diode D1, D2 rectification again after capacitor C 2 filtering, and generation+5V voltage is directly supplied with ic chip 1 and accessory circuit thereof; The external crystal oscillator Z of IC1 the 4th, 5 pin, capacitor C 3, C4 form stable oscillating circuit, provide stable oscillation stationary vibration by crystal oscillator Z, capacitor C 3, C4; Starting high level reset circuit includes capacitor C 3, resistance R 3; When circuit just powers up, a high level pulse is provided for ic chip 1 reset terminal the 1st pin, reach the purpose that resets.The comparative voltage circuit includes potentiometer RP and resistance R 4, R7, R6; Comparative voltage is provided for P1.0, the P1.1 port of ic chip 1.R6 is photo resistance, and its resistance reduces along with the enhancing of light, when illumination hour, the current potential of P1.1 mouth is higher than the current potential of P1.0 mouth, P3.6 mouth output low level; The current potential of P1.1 mouth is less than the current potential of P1.0 mouth when illumination is big, and the P3.6 mouth is exported high level.Ic chip 1 is AT89C2051, its internal structure an analog signal comparator, its input is linked P1.0 and P1.1 mouth, second function of P1.0 and P1.1 mouth is respectively the homophase input and the reverse input end of comparator, comparative result deposits the register of P3.6 mouth correspondence in, and the P3.6 mouth is at the outside no pin of AT89C2051.Regularly closing circuit for lamp includes clock chip T and controllable silicon SCR; Guarantee to close color lamp on time at a certain setting-up time (as point in evenings 12).Relieving circuit includes resistance R 9, R8, triode VT and relay GT; Remove controllable silicon SCR at day conducting, guarantee that P1.0, P1.1 port carry out normal current potential relatively.Six ports of P1.1-P1.6 are as the output port of color lamp LED on the ic chip 1, and color lamp LED does the bright light change that is interrupted.
LED1-LED6 is common luminous color lamp, just often does the bright light change that is interrupted.At day, photo resistance R8 resistance increases, triode VT conducting, and relay GJ gets electric release, and controllable silicon SCR is removed from circuit, recovers P1.0, P1.1 ambient light illumination is monitored.At this moment, RP, R4, R6, R7 begin effect, play the effect of the P1.0 and the P1.1 mouth voltage of comparison ic chip 1.After the colour of sky grew dark, the R6 resistance increased, and the P1.1 port is higher than the P1.0 port in the ic chip 1, P3.6 mouth output low level, and after 30 seconds time-delays judgement, color lamp LED1-LED6 gets electric, flashes by bright, the alternate rule of going out.During 12 of that night, trigger impulse of timer output, controllable silicon SCR works, and drags down the P1.1 port voltage, and color lamp is deactivated thereupon.
The present invention compared with prior art has remarkable energy saving effect, can sufficient lighting hours is provided for the people of nocturnalism in Various Seasonal.
Description of drawings
Fig. 1 is a circuit diagram of the present invention.
Embodiment
Luminous color lamp LED1-LED6 adopts φ 5mm high brightness diode; The model of adjustable resistance RP is 10K; Relay GJ adopts HRS2H-S-5V; Photo resistance R7, R8 adopt GL3516; Triode VT adopts V9015; Crystal oscillator Z adopts 11.0592; Resistance R 1-R5 is respectively 100 Ω, 470K, 10K, 4.7K, 22K; Capacitor C1-C5 is respectively 1uF, 470uF, 10uF, 30PF, 30PF; Voltage stabilizing didoe VDZ adopts 1W5.1V; Rectifier diode D1-D2 adopts IN4007; Controllable silicon SCR adopts MCR100-B.Clock chip T adopts SD2098A.
After the darkness, ambient light illumination reaches the demand of turning on light, and the R6 resistance increases, and P1.1 mouth current potential is higher than the P1.0 mouth, P3.6 mouth output low level, and after 30 seconds time-delays judgement, the P1.2-P1.7 mouth flashes by bright, the alternate rule of going out.At 12 o'clock in evening, trigger impulse of timer output, SCR drags down P1.1 port current potential, and color lamp is deactivated in advance.When the quick resistance R 8 resistances increase of time daybreak, the V9012 conducting, relay GJ gets electric release, and SCR is removed from circuit, recovers P1.0, P1.1 ambient light illumination is monitored.
AT89C2051 has 32 programmable Is/O mouth line, and its inner integrated analog comparator is exactly because integrated analog comparator has taken another root lead-in wire, the output of comparator has taken an I/O mouth, be the P3.6 mouth, pin P3.6 does not pick out, so few I/O mouth line.When programming, P3.6 just can only be used for having read the state of comparator, can not be used for driving equipment such as outside indicator light as other I/O mouth, and this analog comparator can under developmently save the trouble that adds comparator.
