Description
Technical field
The present invention relates to a kind of pedestrains safety detection and prior-warning device, belong to car safety equipment technical field.
Background technology
Along with the fast development of economic society, the owning amount of automobile is in continuous growth, the accident bumping against pedestrian in traffic accident is also more and more frequent, wherein major part reason is owing to the awareness of safety of officer is lower, not having the traffic accident that Timeliness coverage pedestrian causes, this accident not only causes huge property damage, more causes serious personal injury, to individual, family and society cause huge negative influence.
Summary of the invention
It is an object of the invention to: providing a kind of pedestrains safety detection and prior-warning device, can realize early warning in advance, officer can be assisted when dangerous to brake in advance, this system principle is simple, practical, to overcome the deficiencies in the prior art.
The technical scheme of the present invention
A kind of pedestrains safety detection and prior-warning device, comprise motor vehicle, it is provided with pedestrian detection device in motor vehicle front end, phonetic alarm device is arranged in motor vehicle driver position, assist brake device is connected with brake of motor-driven vehicle device, core controller is arranged in motor vehicle, pedestrian detection device is connected with the input terminus of core controller, the output terminal of core controller is connected with assist brake device and phonetic alarm device, this device can realize the personnel before real time scan to motor vehicle through situation, and feed back to driver there in time and assist driver to brake in advance.
The detection of aforementioned pedestrains safety is with prior-warning device, described pedestrian detection device comprises vehicle-borne CCD camera and digital signal processor DSP, the area coverage that the area coverage of vehicle-borne CCD camera is front headlight of motor vehicle is consistent, vehicle-borne CCD is arranged on automobile front upper place, for obtaining the video image in front;Described digital signal processor DSP store different classes of pedestrian contour information and be responsible for the pedestrian contour information that obtains by CCD camera of comparison and between pedestrian and measuring and calculating motor vehicle Distance geometry relative to vehicle position, and by measuring and calculating pedestrian and motor vehicle and traveling speed, determine whether dangerous, and the area coverage of this vehicle-borne CCD camera to be the area coverage of front headlight of motor vehicle consistent, can effectively prevent this system by surrounding environment influence.
The detection of aforementioned pedestrains safety is with, in prior-warning device, described assist brake device comprises magnetic and establishes pass and magnetic electrical contact controller by cable.
Owing to adopting technique scheme, compared with prior art, the principle of the invention is simple, easy to operate, front pedestrian contour information, walking speed relative to vehicle position and pedestrian can be obtained in advance, whether digital signal processor DSP obtains compares with the pedestrian contour information stored after pedestrian contour information to determine as pedestrian, then contrast according to the correlation circumstance of motor vehicle self speed and pedestrian, if it is dangerous, while giving a warning to officer, auxiliary officer brakes in advance, it is to increase the security that trap for automobile travels.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
Embodiments of the invention: a kind of pedestrains safety detection and prior-warning device, as shown in Figure 1: comprise motor vehicle 1, it is provided with pedestrian detection device 2 in motor vehicle 1 front end, phonetic alarm device 3 is arranged in motor vehicle 1 driver position, assist brake device 4 is connected with motor vehicle 1 braking devices, core controller 5 is arranged in motor vehicle 1, wherein pedestrian detection device 2 is connected with the input terminus of core controller 5, the output terminal of core controller 5 is connected with assist brake device 4 and phonetic alarm device 3, pedestrian detection device 2 comprises vehicle-borne CCD camera and digital signal processor DSP, wherein the area coverage of vehicle-borne CCD camera is that the area coverage of motor vehicle 1 headlight is consistent, assist brake device 4 comprises magnetic and establishes pass and magnetic electrical contact controller by cable.
Specifically implement principle
As shown in Figures 2 and 3: have pedestrian when the CCD camera being arranged on motor vehicle front end scans front, and relevant for pedestrian data (pedestrian contour, speed of walking relative to vehicle position and pedestrian) are inputted in dsp processor, dsp processor is comprehensively analyzed according to Motor vehicles its data (travelling speed and self-position) data relevant to pedestrian, judge that whether front is people and whether dangerous accident, if dangerous, opening voice is reported to the police and is assisted drift stop to start and assist driver's braking.
