Background technology
At field of traffic, no matter charge station's toll island head or highway fog area, traffic alarming fog lamp all is absolutely necessary.The Fog-proof light of using all adopts civil power or the round-the-clock power supply of solar energy at present, yet under the situation fine, that visibility is very high, Fog-proof light still operate as normal not only cuts little ice, and increases the waste of the energy on the contrary.Therefore, needs are a kind of can be according to the power of visibility, and the traffic alarming fog lamp of closing automatically, starting solves the present situation of present energy waste.
The utility model content
In order to overcome traffic alarming fog lamp under the very high situation of visibility, the still in running order and energy waste that causes, the purpose of this utility model provide a kind of can be according to the power of visibility, the traffic alarming fog lamp of closing automatically, starting.
To achieve these goals, the technical solution of the utility model comprises: a timing control circuit, as core devices; One rectification circuit is for timing control circuit provides dc source; One display circuit, the output signal of reception timing control circuit; One photo resistance control circuit, output links to each other the stroboscopic speed of control timer opening and closing and display circuit with timing control circuit.
Wherein: described photo resistance control circuit comprises the multivibrator that is made of the first～two diode, first resistance, the 3rd resistance, first electric capacity, and the stroboscopic control circuit that is made of bleeder circuit and first triode and the 4th resistance; Described display circuit is made up of through series-parallel system super bright yellow light-emitting diode; Described timing control circuit is selected 555 timers for use.
The utlity model has following advantage:
The utility model is used for toll island island head or along expressway fog zone section both sides, when greasy weather or weather anomaly, closes automatically or starts traffic alarming fog lamp and make sight line inducing to the driver according to the power of visibility.Simple in structure, practical, and well play energy-conservation effect, avoided the waste of the energy.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Fig. 2 is the utility model circuit theory diagrams.
The specific embodiment
Be described in further detail below in conjunction with drawings and Examples the utility model.
As shown in Figure 1, the utility model is made up of following four parts:
One timing control circuit, core devices is 555 timers, is used for driving and controlling the strobe rate of the super bright LED of display circuit, is core of the present utility model.
One photo resistance control circuit is by the stroboscopic speed of photo resistance control startup and closing controller and display circuit.
One display circuit, the output signal of reception timing control circuit adopts super bright yellow led display circuit, and it is made up of by series-parallel mode super bright LED.
One rectification circuit is used to timing control circuit (timer) that DC voltage is provided.
Circuit theory as shown in Figure 2, U1 is core devices 555 timers of timing control circuit, system combines 2 pin and 6 pin of timer U1,7 pin connect the adjustable potential meter R2 sliding end of photo resistance control circuit; 4 pin of timer U1 are the zero clearing control end, connect stroboscopic control circuit in the photo resistance control circuit.The photo resistance control circuit comprises the multivibrator that is made of the first～two diode D1～D2, first resistance R 1, the 3rd resistance R 3, first capacitor C 1, and the stroboscopic control circuit that constitutes by bleeder circuit and the first triode Q1 and the 4th resistance R 4, by regulating the adjusting that adjustable potential meter R2 realizes the multivibrator output duty cycle, this circuit is because of having added the first diode D1, the second diode D2, use first capacitor C 1 of different value, make the charge and discharge time constant by regulator potentiometer, can realize the adjusting of different flicker frequencies.Wherein the bleeder circuit formed by photo resistance R6 and the 7th resistance R 7 of stroboscopic control circuit drives the base stage of the first triode Q1, and the first triode Q1 colelctor electrode links to each other with timer U1 by the 4th resistance R 4.
Display circuit is by the 5th resistance R 5, LED, and second capacitor C, 2, the second triode Q2 form, and the 5th resistance R 5 one terminations are received the output signal of timer U1, another termination second triode Q2 base stage; Second capacitor C 2 is connected between 5 pin and ground of timer U1, and LED inserts the colelctor electrode of the second triode Q2.
The utility model principle: under the visibility normal condition, photo resistance R6 resistance is very little, the 7th resistance R 7 both end voltage enough drive the first triode Q1 transistor base makes its road logical, so 4 pin of timer U1 are in low level state, and system is in cleared condition; When visibility reduces, the resistance of photo resistance R6 increases, make the 7th resistance R 7 both end voltage reduce, can't drive the base stage of the first triode Q1, this moment timer U1 4 pin by resistance R 4 voltages by on draw and be high level, system is in normal operating conditions, the 3 pin output fixed frequency oscillator signal of timer U1 drives the base stage of the second triode Q2 through the 5th resistance R 5 in the display circuit, the control LED shows, realizes stroboscopic control.
The utility model course of work is: under the situation of visible light abundance, and the timing control circuit zero clearing, traffic alarming fog lamp is in power save mode, promptly stops stroboscopic operation.During unusual or night, visibility drops to a certain degree when weather, and by the induction of photosensitive resistance, timing control circuit resets, and makes system be in the stroboscopic operation state automatically.Can make sight line inducing in bad weather startup in time and to the driver, can under good weather, avoid the waste of the energy again.
