Description
Technical field
The utility model relates to the automotive lighting control field, is specifically related to the nearly distance light of a kind of automobile automatically conversion and obstruction warning device.
Background technology
At present, the nearly country beam change-over swith of automobile all is to adopt manually or foot operation, driver's night sight distance is nearer, the energy high concentration, the nearly country beam change-over swith of frequent operation easily causes driver fatigue and dispersion attention, therefore, during night travel, disturbs because nearly country beam conversion is untimely the pilot's line of vision initiation traffic accident happen occasionally.
On the existing market, there is automobile to adopt far and near lamp auto-changing system, but, most photoconductive cells of using are as detective cell, photoconductive cell easily is subject to the interference of external light source, lamp or vehicle lamp brightness are not lower if the vehicle on opposite is driven for some reason, then can't realize the automatic conversion of far and near lamp, can affect traffic safety.
Summary of the invention
Shortcomings and deficiencies for prior art, the purpose of this utility model is to provide the nearly distance light of a kind of automobile automatically conversion and obstruction warning device, can automatically change nearly far lighting, and at meeting or when running into obstacle, can also further remind the driver to drive with caution.
For realizing above-mentioned technical purpose, the utility model takes following technical solution to be achieved.
The nearly distance light of a kind of automobile is conversion and obstruction warning device automatically, comprise nearly distance light change-over swith, micro controller system, the optical sensor that is connected with the micro controller system first input end, the control end of the described near distance light change-over swith that is connected with micro controller system the first mouth, it is characterized in that, the second input end of described micro controller system is connected with distance measuring sensor, and the second mouth of micro controller system is connected with annunciator.
Further characteristics and the improvement of technique scheme are:
Described optical sensor and distance measuring sensor are installed on the Federal bumper middle part, and described micro controller system and annunciator are installed in the gauge panel of automobile.
Described micro controller system adopts the AT89C52 micro controller system.
The ASR100 millimeter wave radar that described distance measuring sensor adopts German Adc Inc. to produce.
Described optical sensor adopts photoconductive cell and modulus conversion chip to realize; Described photoconductive cell adopts the GL5537 photoconductive cell, and described modulus conversion chip adopts the PCF8591T chip.
In the automatic conversion of the nearly distance light of automobile of the present utility model and the obstruction warning device, increasing has distance measuring sensor and annunciator, by optical sensor and the light situation of change of distance measuring sensor difference Real Time Monitoring vehicle front and the distance between automobile and the obstacle, and these input informations are processed to micro controller system, thereby make the automatically response of conversion and obstruction warning of nearly distance light.The utility model not only can be identified the vehicle that the opposite is come, and can identify the potential threats such as three-wheel vehicle, motor bike, pedestrian, has simultaneously the characteristics such as sensitivity is adjustable, reliability is high, easy to operate, lightweight, volume is little.
Description of drawings
Below in conjunction with accompanying drawing with implement the specific embodiment and the utility model is done further described in detail most.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, automatically to change and the obstruction warning device for the nearly distance light of a kind of automobile of the present utility model, its optical sensor and distance measuring sensor are installed on the Federal bumper middle part, and micro controller system and annunciator are installed in the gauge panel of automobile.
Wherein, micro controller system adopts the AT89C52 micro controller system.The optical sensor that the micro controller system first input end connects, optical sensor adopt photoconductive cell and modulus conversion chip to realize; Photoconductive cell adopts the GL5537 photoconductive cell, modulus conversion chip adopts the PCF8591T chip, the simulation light sampled signal of photoconductive cell becomes digital light sampled signal after by modulus conversion chip, the mouth of modulus conversion chip is connected with the first input end of micro controller system, receives digital light sampled signal.The second input end of micro controller system connects distance measuring sensor, and the ASR100 millimeter wave radar that distance measuring sensor adopts German Adc Inc. to produce provides distance between automobile and the obstacle to micro controller system.Micro controller system the first mouth connects the control end of nearly distance light change-over swith, by can control the nearly distance light conversion of automobile near the distance light change-over swith.The second mouth of micro controller system connects annunciator, and warning device is buzzer phone, sounds a buzzer during warning.
In the time of behind the automobile starting, the nearly distance light of above-mentioned automobile automatically changes and the obstruction warning device is opened.When photoconductive cell detects the light of sending a car on the opposite, immediately the optical signal that detects is converted to electric signal and is sent to micro controller system; Simultaneously, the ASR100 millimeter wave radar that distance detects is also carrying out work, launched microwave, when there was obstacle in the place ahead, radar received reflection echo, produce range signal, and will be converted to electric signal with the range signal of obstacle and be sent to micro controller system, micro controller system carries out following processing: (1) when optical sensor without the efficient light signal, rang sensor is during without the active distance signal, the control automobile front is distance light, not buzzer warning; (2) optical signal is arranged when optical sensor, rang sensor is during without the active distance signal, and the control automobile front is dipped beam, not buzzer warning; (3) when optical sensor without the efficient light signal, when rang sensor had range signal, the control automobile front was distance light, buzzer warning; (4) optical signal is arranged when optical sensor, when rang sensor had range signal, the control automobile front was dipped beam, simultaneously buzzer warning.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art in the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification sheets, these all belong to the row of the utility model protection.
