Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure that the utility model car bulb is opened switching device shifter automatically as shown in Figure 1, comprise and be arranged on the procephalic light sensor 2 of car, as shown in Figure 2, the circuit structure of light sensor 2 comprises the phototriode 22 that NPN type triode 21 that the model that is connected with positive source is respectively S9013 and model are 3DU5D, the base stage of NPN type triode 21 is connected with the emitter of phototriode 22, the emitter of NPN type triode 21 is connected with analog to digital converter 3 with slide rheostat 23 respectively, microcontroller 1 is also connected with respectively pressurizer 4, car light controller 5, LCDs 6 and buzzer 7.
Principle of the present utility model is: light sensor 2 is converted to digital signal by the light strong and weak signals sensing by analog to digital converter 3, transfers to microcontroller 1 to process.By microcontroller 1 coding is judged, in the time that intensity of illumination is less than a certain set point, can judge current is driving at night, and car headlamp is opened; In the time that intensity of illumination is less than a certain fixed value all the time, can judge that road light is dark, and subtend is without sending a car, and switches high beam; During this period, if intensity of illumination increases, can judge that subtend sends a car, or this section light is good, now switches dipped headlights; If intensity of illumination reduces at short notice again, switch high beam; In the time that intensity of illumination continues to be greater than a certain set point, can judge that current light is good, do not need to open light, light is closed, and realizes automatic unlatching and the switching of light with this.
As shown in Figure 2, the size of current of phototriode 22 is flow through in illumination control, this electric current is exaggerated through NPN type triode 21, the emitter of NPN type triode 21 connects power supply ground through slide rheostat 23, voltage is exported by the emitter of NPN type triode 21, and the amplitude of variation of this voltage can regulate by slide rheostat 23.
When use, light sensor 2 is converted to digital signal by the light strong and weak signals sensing by analog to digital converter 3, transfers to microcontroller 1 to process, and the every 100ms of microcontroller 1 reads the analogue value that light sensor 2 is exported, and judges environmental light intensity.For the transition stage from daytime to night, need to set the threshold value of a voltage, this threshold value is set by user.In the time that unglazed photograph or illumination can be ignored, photoelectric sensor 2 circuit output voltage values, below 1.5V, can judge that current environment is as night, and microcontroller 1 is opened high beams by car light controller 5 control relays; During this period, in the time having light-illuminating, output voltage obviously raises, between 1.5～4.5V, occurrence is relevant with intensity of light, can judge that subtend is sent a car or this section light is good, and now microcontroller 1 switches dipped headlights by car light controller 5 control relays; If voltage is reduced to below 1.5V at short notice again, microcontroller 1 switches high beam by car light controller 5 control relays again; Under bright natural light environment, output voltage is more than 4.5V, can judge that current light is good, environment is daytime, do not need to open light, microcontroller 1 cuts out light by car light controller 5 control relays, realizes automatic unlatching and the switching of light with this, and pressurizer 4 provides power supply for microcontroller 1, car light controller 5, LCDs 6 and buzzer 7.
The utility model car bulb is opened switching device shifter automatically, solve existing car bulb and easily caused not in time the problem of traffic accident with improper use because of manual switchover, simple in structure, easy to use, ensure traffic safety, effectively reduce because light is abused all kinds of security incidents that cause, and alleviate to a certain extent driver's degree of fatigue.
