Abstract
The utility model discloses an automatically adjustable delay-action road lamp controlling switch. The adjustable delay-action circuit breaker controlled by light and temperature overcomes the defect of tradition controlling switches which can not change the lighting time appropriately according to changes of seasons. The oscillating period of a clock generator of an integrated circuit is in dependency with the variation of the resistance of a thermistor; a base of a crystal triode which is arranged in a light controlled trigger switch makes the light controlled trigger switch switched-off in time after a clock signal is frequency divided by a frequency divider, achieving the function of automatically adjusting of the delay-action. The adjustable delay-action circuit breaker controlled by light and temperature is simple and reliable and can be used for automatically controlling for a wide range.
Description
The utility model discloses a kind of automatic adjustment delay switch that street lamp opens and closes automatically of controlling.Belong to street lamp automatic control technology field.
Three kinds of forms such as that present various street lamp control switch can be divided into is light-operated, time control and light-operated time control combination.The subject matter that exists is to regulate the needs of night illumination situation according to Various Seasonal.Though complex structure, especially the form with light-operated time control combination is more outstanding, and function is incomplete.
Goal of the invention of the present utility model provides a kind ofly can regulate the light temperature control adjustable delay switch of time-delay length with the Various Seasonal variation of temperature.
Technical essential of the present utility model is:
1, the sensitization control circuit has adopted the integrated circuit trigger switch of photo resistance control, has designed the R1C1 integrating circuit to get rid of the influence of various moment light changes in circuit.
2, time-delay mechanism has adopted 555 integrated circuit clock generators and 4020 integrated frequency dividers.Its circuit is simple and reliable, and delay time is regulated more convenient feasible.This circuit clock generator is controlled by light controlling device, and only this circuit just produces the clock trigger behind light-operated gating.In addition, this circuit is controlled by timing circuit again.After time-delay finishes, the 3 pin output signals of IC3, the blocking relay control circuit makes the clock circuit locking simultaneously.
3, in clock circuit, considered because of the temperature influence, night-light light application time difference has installed temperature-control circuit additional, at lighting hours weak point cold season, and long in hot time lighting hours, this function is controlled the clock cycle by the positive temperature pipe thermistor Rt of system and is finished.
4, power unit adopts the commercial power rectification stabilized voltage power supply and battery is in parallel uses, and battery is not powered when mains-supplied, and battery send electricity after the civil power outage, does not change because of outage with the various operating states of holding circuit.
Following according to Figure of description, further introduce formation of the present utility model and operation principle:
Among the figure, DB is a step-down transformer, and civil power by diode D2, D3, D4, D5 rectification, 7809 voltage stabilizings of three end integrated stable voltage circuits, provides DC power supply through diode D6 isolation with the use in parallel after D7, D8 step-down of 9V battery after the DB step-down.R5C5 prevents to produce instant power-down when two power supplys from switching and designs.
IC1 integrated circuit and peripheral cell constitute light-operated trigger switch.Bright when sufficient at light, R
λResistance is less, and the B point voltage is higher than the valve value of IC1.3 pin output low levels, BG2 ends, not adhesive of relay, lamp is not lighted.R when the light deepening
λResistance increases, and B point current potential reduces.When its value was lower than IC1 valve value, the upset of 3 pin was high level, the J adhesive, and lamp is bright.Wherein R1C1 is an integrating circuit.When extraneous moment, light became, B point current potential instantaneous variation.Because effect 2, the 6 pin current potentials of R1C1 do not suddenly change, and make circuit have vulnerability to jamming.Regulate the brightness of starting to control that W1 can regulating circuit.R3C2 designs for increasing the anti-interference of IC1 self.
IC2 and peripheral circuit constitute clock generator.4 pin are controlled by the output level of IC1, and only when IC1 output high level, clock circuit is just worked.C3, W2, Rt and R4 and IC2 constitute square-wave oscillator circuit.Regulate W2 scalable cycle of oscillation, the variation of Rt resistance also influences cycle of oscillation, its reflection be the variation of temperature.
IC3 is integrated frequency divider.10 pin connect the clock input, and 3 pin are frequency division output, and its branch frequency is 2
13=8192, i.e. the cycle of 3 pin output high level is 8192 times of clock cycle.BG1 is saturated when first high level appears in 3 pin, and BG2 ends, and relay discharges.4 pin of IC2 are low level also simultaneously, and clock circuit quits work, and the IC3 operating state does not change, when the IC1 trigger overturns to high level for the second time, offer quenching pulse of 11 pin of IC3 by R7C8,3 pin become low level, BG1 ends, and delay working restarts.
In sum, a kind of smooth temperature control adjustable delay switch, comprise the non-stop run power supply of ac/dc parallel operation and by integrated circuit (IC1), transistor (BG1, BG2), the light-operated trigger switch that relay (J) is formed, it is characterized in that by integrated circuit (IC2), the clock generator that thermistor (Rt) is formed temperature control scalable cycle of oscillation is connected with the frequency divider of being made up of integrated circuit (IC3), the output of frequency divider (IC33 pin) connects the formation control loop with the base stage of the transistor (BG1) of light-operated trigger switch, the output of the integrated circuit of light-operated trigger switch (IC1) (3 pin) joins control end (3 pin of the IC1) formation that the links control loop of clock generator integrated circuit (4 pin of IC2) control end and light-operated trigger switch with the capacitance-resistance series loop that the clear terminal (11 pin of integrated circuit (IC) 3) of frequency divider is formed through resistor (R7) capacitor (C8).
The utility model in use, according to the region difference variation in the different four seasons, the potentiometer W2 that will connect with thermistor Rt adjusting suitably gets final product.Can be widely used in the control of road lighting lamp.
Major advantage of the present utility model is that structure is fairly simple, can be according to the delay value of temperature different adjustment switch to adapt to the illumination needs of Various Seasonal.Adopted anti-jamming circuit can ensure that this device has reliable and stable result of use in addition.
Figure of description 1 is an electrical schematic diagram of the present utility model.
Among the embodiment of the present utility model, integrated circuit (IC) 1, IC2 have adopted time-base circuit NE555 integrated circuit.IC3 has adopted 4020 integrated circuit frequency dividers.
