Abstract
The utility model discloses an automobile device for preventing rear-end collision. The automobile device is characterized by comprising a singlechip, a radar sensor, a CCD camera, an audio decoder and a loudspeaker, wherein an output end of the radar sensor and an output end of the CCD camera are respectively connected with an input end of the singlechip, one output end of the singlechip is connected with an input end of the loudspeaker through the audio decoder, and the other output end of the singlechip is connected with a car light. A driver of an automobile driven on an urban road is reminded to pay attention to keeping space through scientific information acquisition and judgment, the rear-end collision is prevented, safety of driving the automobile is improved, passengers and the driver are protected, and a traffic jam is prevented.
Description
Technical field
The utility model relates to a kind of Vehicular device, specifically is a kind of Vehicular device that prevents rear-end collision, and this device is applicable to various automobiles.
Background technology
Economic development along with China, in by the end of June, 2012 automobile pollution above 1.1 hundred million, the automobile pollution in 17 cities, the whole nation is above 100 ten thousand, wherein the automobile pollution in 5 cities such as Beijing, Chengdu, Tianjin, Shenzhen, Shanghai surpasses 2,000,000, and a lot of cities very easily blocked up in peak period.Traffic congestion causes that vehicle is irregular to stop and go, and has increased the driving intensity of automobile driver greatly, a lot of automobiles therefore and front vehicles collide, cause knocking into the back.Though the Reverse Sensor of prevention automobile tail collision is arranged now, and its distance by the disturbance in judgement thing is come early warning, travelling at automobile positive does not have ready-made warning device.A lot of automobiles so the front truck that knocks into the back cause damaged vehicle, threaten occupant's safety, and are once causing interruption of communication.
Summary of the invention
Defective or deficiency at the prior art existence; the purpose of this utility model is; a kind of Vehicular device that prevents rear-end collision is provided; this device can in time be reminded at urban highway traveling automobile chaufeur and note maintaining safe distance; prevent to knock into the back front truck; improve the driving safety of automobile, protection passenger, and prevention traffic jam.
In order to realize above-mentioned technical assignment, the utility model adopts following technical scheme to be achieved:
A kind of Vehicular device that prevents rear-end collision is characterized in that, comprises micro controller system, radar sensor, CCD camera, audio decoder and loud speaker; Wherein, the mouth of described radar sensor, CCD camera connects the input end of micro controller system respectively, and a mouth of micro controller system connects the input end of described loud speaker by audio decoder, and another mouth connects car light.
Other technologies of the present utility model are characterized as:
Described radar sensor adopts the YB-P802 radar sensor.
Described CCD camera adopts the KM-343CG camera.
Described micro controller system adopts the TMS320C6713B micro controller system.
Described audio decoder adopts the TLV320AIC23 audio decoder.
Described loud speaker adopts the JBS-502 loud speaker.
The utility model can make traveling automobile note maintaining safe distance by information acquisition and the judgement of science, slows down in advance or parking, prevents the front truck that knocks into the back, and improves the driving safety of automobile, and the prevention traffic jam.
Description of drawings
Fig. 1 is structural principle scheme drawing of the present utility model.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
The specific embodiment
Embodiment:
As shown in Figure 1, the Vehicular device of the prevention rear-end collision of present embodiment, comprise the TMS320C6713B micro controller system, the YB-P802 radar sensor, the KM-343CG camera, TLV320AIC23 audio decoder and JBS-502 loud speaker, described YB-P802 radar sensor, camera is connected with micro controller system respectively with audio decoder, described loud speaker is connected with audio decoder, micro controller system in the device also is connected with automobile headlamp, wherein: the YB-P802 radar sensor is installed on the automobile front beam lower end, and this YB-P802 radar sensor and automobile headlamp are positioned on the same horizon, and the KM-343CG camera is installed on YB-P802 radar sensor side; The TLV320AIC23 audio decoder is installed on the center instrument panel place; The JBS-502 loud speaker is installed on the preceding instrument desk.
The process of present embodiment work is as follows:
When automobile starting travels, at first radar sensor is launched continuous harmonic ringing, when running into automobile or other obstacle at travel direction, radar sensor receives the echoed signal with certain time-delay, and this moment, micro controller system judged that vehicle heading has automobile or obstacle and judging distance and the current speed of a motor vehicle; At this moment, micro controller system is opened CCD camera measuring distance again, and this information is transferred to micro controller system, confirms to carry out secondary.Conform to if receive judgement with radar, micro controller system judges whether car light is opened, if car light is opened, makes car light scaling transformation intensity according to distance and the speed of a motor vehicle, and therefore chaufeur obtains reminding; Loud speaker sends voice suggestion simultaneously, and chaufeur is noted slowing down or stopping.
