Description
Technical field
The present invention relates to a kind of automobile light controller, particularly relate to a kind of car light intelligence control system。
Background technology
Motor traffic accidents be because that sight line is unclear and human brain mixed Tun is unclear that lamplight pointing cannot be selected to cause, do not open just lane change such as steering indicating light and have an accident etc.。Thus visible auto lamp is great to the safety effect of running car。
Dawn and at dusk, weather is dim, the eye pupil of people is in the state that day alternates with night, the identification ability of CF is more weak, the pollution in city has more increased the weight of this dusky sensation, and the car being equipped with automatic headlight now can sense the change of light in time. and automatically turn on headlight, not only illuminate road surface in time, the driver also allowing other notices your car, thus being greatly improved the safety of driving.
The car owner of more than 40% can select silver gray and dark automobile, and this type of body color easily incorporates among rather dark background, is difficult at a distance distinguish, therefore when visibility is relatively low, silver gray and dark color are still prominent by the safety effect of automatic headlight.
Summary of the invention

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention includes MCU, natural environment photoelectric sensor circuit (concrete principle is as shown in Figure 2), Hall element (concrete principle is as shown in Figure 3), A/D circuit, light driving circuit, lamp, power circuit and switch, power supply is connected with described power circuit by described switch, described power circuit is connected with described light driving circuit and described MCU simultaneously, described natural environment photoelectric sensor circuit is connected with described MCU by described A/D circuit, described Hall element is connected with described MCU, the control output end of described MCU is connected with described lamp by described light driving circuit, described Hall element is two groups, described light driving circuit is many groups, light driving circuit correspondence described in one group connects a lamp。
Further, described lamp is any one in car light；Described MCU is the one in AT89C51 series monolithic, PIC series monolithic, STP series monolithic；Described power circuit is electronic switching circuit (as shown in Figure 4)。
Controller operation principle for automatic vehicle light controller is: photoelectric sensor is to utilize optical principle, adopt advanced photoelectric conversion technique, the output of electricity can change with the change of ambient, the electricity of this change is sent in the control circuit being made up of microcomputer, microcomputer is by numerous and diverse computational methods, to obtain a result and send headlight drive circuit, and go to drive automobile lampet, headlight, dipped beam and steering indicating light。Replace manual operation, alleviate driver's working strength, improve safety。
Hall element is according to Hall effect the one of magnetoelectric effect (Hall effect be), field intensity according to the magnetic field that diverse location reflection sources is given, control the steering indicating light of different directions, when alternating magnetic field is through the sensor of out-of-date generation output voltage pulse, owing to the field intensity of excitation field determines the amplitude of potential pulse。The electricity of these changes being sent in the control circuit being made up of microcomputer, microcomputer, by numerous and diverse computational methods, will be obtained a result and send headlight drive circuit and remove driving automobile lampet, headlight, dipped beam and steering indicating light。Such as, the sensor of one position, control left steering lamp, the sensor of two positions controls right turn lamp, as long as and the sensor of two positions changes, and photoelectric sensor recognizes under the state being dark, also can switch to the replacement manual operation of dipped headlights, alleviate driver's working strength, improve safety。
Light intelligent controller is inputted by multiple light sensors, light automatic control switch close, with withdrawing, the switch recovering depot's function, is formed by with all lamp output of automobile。By sense ambient light and shade automatically control all lamps of automobile bright secretly。The device that switch is not manually stirred when " light automatically controls " position。
" light automatically controls " divides four tunnel outputs to control automobile lighting system by main frame MCU: the distance-light of headlight, two-way driving lamp, steering indicating light, instrument panel lamp。Circuit system is independent, and former car light group circuit parallel, does not change former car circuit wiring system
When ignition switch is as ACCON, when ambient is unfavorable for running car, main frame MCU will automatically turn on illuminator, including headlight (long-and-short distant light), two-way driving lamp, instrument panel lamp etc.。To guarantee your traffic safety。
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described。Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention。Claimed scope is defined by appending claims and equivalent thereof。
