Description
Technical field
The utility model relates to signal and amplifies and digital integrated circuit control system field, is specifically related to a kind of street lamp control system based on photo resistance.
Background technology
At present, reducing energy consumption, energy savings, emphasis environmental protection is controlling the trend of the world today, and high energy consumption and the incandescent lamp that can aggravate greenhouse effect are more and more out of favour.After announcing the timetable of " European Union will close down incandescent lamp the year after next ", the die is cast to abandon successively incandescent lamp all over the world, and environment-friendly type energy-saving fluorescent lamp is the replacer of incandescent lamp.At the public place of unit and the public corridors of residential block such as school, office, industrial enterprise, altar lamp phenomenon is very general, and this has caused the significant wastage of the energy.In addition, due to frequent switch or human factor, the spoilage of switch on wall is very high, has increased maintenance capacity, has wasted fund.Simultaneously along with the aging danger of electricity silk is also large.
Summary of the invention
For the possibility of economizing on electricity and and to people with safe convenience, the utility model provides a kind of street lamp control system based on photo resistance, has designed the photoacoustic dual-controlled incandescent lighting lamp system of a kind of circuit novelty, safety electricity-saving, simple in structure, easy for installation, long service life.
The technical scheme that the utility model patent adopts is: a kind of street lamp control system based on photo resistance, is characterized in that: comprise that power circuit, signal amplification shaping circuit, acoustic control and light-operated circuit, digital integrated circuit, delayed processing circuit monostable circuit five parts form.Audio-switch and light-operated switch are connected on digital integrated circuit chip respectively.Digital integrated circuit chip adopts CD4011 model.Power circuit is by power transformer, and 4 rectifier diodes form.The core parts of light-operated circuit are photo resistance.Sound acquisition cuicuit adopts cylinder utmost point microphone.
Concrete operations flow process is as follows:
When having voice signal to import into and unglazed while being radiated at photo resistance RGM, RGM resistance is very large, very little to direct-current control voltage decay.The electronic switch conducting that triode and resistance form, makes shunt capacitance charging.Due to be full of electricity the time very rapid, electric capacity is added to Electret condenser microphone control end by resistance direct current trigger voltage after being full of electric charge, electret conducting, bulb is lighted.In electric capacity, electric charge is put to zero time, and electret is replied cut-off state, and lamp extinguishes.Reached and had sound to have the light time, the effect that bulb does not work.
When bulb, light while having new sound source to occur in process, electric capacity is electric discharge again after can again charging, and recalculates the time of lighting.If need to change the bright duration of lamp, only need the parameter of change electric capacity or bypass resistance.Reach while having sound unglazed the effect that bulb is bright.
Adopt the beneficial effect of the utility model patent to be: with the switch on the corridor of sound and light controlled delay switch replacement residential quarters, only after darkness, when there being people's stair passage of passing by, while sending footsteps or other sound, corridor lamp can be lighted automatically, illumination is provided, and when people enter door or walk out apartment, corridor lamp time delay is understood automatic distinguishing after a few minutes.By day, even if there is sound, corridor lamp can be not bright yet, can reach energy-conservation object.Sound and light controlled delay switch is not only applicable to uptown corridor, and be applicable to the public places such as factory, office building, teaching building, it has that volume is little, good looking appearance, making easily, the advantage such as reliable operation, it reduces energy consumption, energy savings, environmental protection simultaneously, is suitable for the lighting apparatus in various buildings corridor.

Embodiment
Embodiment:
The technical scheme that the utility model patent adopts is: a kind of street lamp control system based on photo resistance, is characterized in that: comprise that power circuit, signal amplification shaping circuit, acoustic control and light-operated circuit, digital integrated circuit, delayed processing circuit monostable circuit five parts form.Audio-switch and light-operated switch are connected on digital integrated circuit chip respectively.Digital integrated circuit chip adopts CD4011 model.Power circuit is by power transformer, and 4 rectifier diodes form.The core parts of light-operated circuit are photo resistance.Sound acquisition cuicuit adopts cylinder utmost point microphone.
When voice signal (footsteps, applause etc.) receives and convert to the signal of telecommunication by Electret condenser microphone BM, the base stage that is coupled to VT through C1 is carried out voltage amplification, amplifying signal is delivered to 2 pin of the NAND gate D2 in CD4011, and R4, R7 are the biasing resistors of VT, and C2 is power filtering capacitor.
In order to make sonic-opticalcon trolled switch switch disconnection by day, be that lamp does not work, by elements such as photo resistance RG, form light-operated circuit, R5 and RG form series connection bleeder circuit, when night, environment was unglazed, the resistance of photo resistance is very large, the voltage at RG two ends is high, is t=2 π R8C3 between high period, changes the value of R8 or C3, can change delay time, meet different objects.D3 in CD4011 and D4 form two-stage shaping circuit, and square-wave signal is carried out to shaping.When C3 is charged to certain level, signal is output as high level after NAND gate D3, D4, makes one-way SCR conducting, electronic switch closes; C3 only discharges to R8 after being full of electricity, when discharging into certain level, through NAND gate D3, D4, is output as low level, makes one-way SCR cut-off, and electronic switch disconnects, and completes once complete electronic switch by the process that reaches pass.
Diode VD1～VD4 exchanges 220V to carry out bridge rectifier, becomes Rectified alternating current, again through R1 step-down, is the DC power supply of circuit after C2 filtering, is the power supplies such as BM, VT, IC chip.
Beneficial effect by the utility model patent: with the switch on the corridor of sound and light controlled delay switch replacement residential quarters, only after darkness, when there being people's stair passage of passing by, while sending footsteps or other sound, corridor lamp can be lighted automatically, illumination is provided, and when people enter door or walk out apartment, corridor lamp time delay is understood automatic distinguishing after a few minutes.By day, even if there is sound, corridor lamp can be not bright yet, can reach energy-conservation object.Sound and light controlled delay switch is not only applicable to uptown corridor, and is applicable to the public places such as factory, office building, teaching building, it has, and volume is little, good looking appearance, making easily, the advantage such as reliable operation, be suitable for the lighting apparatus in various buildings corridor.
