Abstract
The utility model discloses a pedestrian safety detecting and early warning device which comprises a motor vehicle. A pedestrian detecting device is arranged at the front end of the motor vehicle, a voice alarm device is arranged at the position of a driver in the motor vehicle, an auxiliary braking device is connected with a motor vehicle braking device, a core controller is arranged in the motor vehicle, the pedestrian detecting device is connected with the input end of the core controller, and the output end of the core controller is connected with the auxiliary braking device and the voice alarm device. The pedestrian safety detecting and early warning device is simple in theory, convenient to operate and capable of acquiring the contour information of pedestrians in front, the positions of the pedestrians relative to the motor vehicle and the walking speed of the pedestrians in advance, the contour information of the pedestrians is compared with stored pedestrian contour information after a DSP acquires the contour information of the pedestrians so that whether the pedestrians exist or not can be determined, then the speed of the motor vehicle is compared with the relevant condition of the pedestrians, if danger happens, a warning is sent to the driver, meanwhile, the driver is assisted in braking in advance, and the safety of automobile road driving is improved.
Description
Technical field
the utility model relates to a kind of pedestrains safety and detects and prior-warning device, belongs to automotive safety equipment technical field.
Background technology
fast development along with economic society, the owning amount of automobile is in continuous growth, the accident that bumps against pedestrian in traffic accident is also more and more frequent, wherein most of reason is because the awareness of safety of chaufeur is lower, do not have to find the traffic accident that pedestrian causes in time, the accident not only causes huge property damage, has more caused serious personal injury, to individual, family and society cause huge negative influence.
Summary of the invention
the purpose of this utility model is: provide a kind of pedestrains safety to detect and prior-warning device, can realize and giving warning in advance, when dangerous, can brake in advance by driver assistance, this system principle is simple, practical, to overcome the deficiencies in the prior art.
the technical solution of the utility model
a kind of pedestrains safety detects and prior-warning device, comprise self-propelled vehicle, at self-propelled vehicle front end, be provided with pedestrian detection device, phonetic alarm device is arranged on driver position in self-propelled vehicle, auxiliary brake is connected with braking device for motor vehicle, core controller is arranged in self-propelled vehicle, pedestrian detection device is connected with the input end of core controller, the mouth of core controller is connected with phonetic alarm device with auxiliary brake, this device can realize real time scan to the personnel before self-propelled vehicle through situation, and feed back in time driver there and assist driver to brake in advance.
in aforementioned pedestrains safety detection and prior-warning device, described pedestrian detection device comprises vehicle-borne CCD camera and digital signal processor DSP, the area coverage of vehicle-borne CCD camera is that the area coverage of front headlight of motor vehicle is consistent, vehicle-borne CCD is arranged on automobile front upper place, for obtaining the video image in the place ahead; Described digital signal processor DSP store different classes of pedestrian contour information and be responsible for pedestrian contour information that comparison obtained by CCD camera and pedestrian and measuring and calculating place self-propelled vehicle between distance and with respect to vehicle position, and by measuring and calculating pedestrian and self-propelled vehicle and moving velocity, determine whether dangerous, and the area coverage that the area coverage of this vehicle-borne CCD camera is front headlight of motor vehicle is consistent, can effectively prevent that this system is by surrounding environment influence.
in aforementioned pedestrains safety detection and prior-warning device, described auxiliary brake comprises magnetoelectricity switch and magnetoelectricity on off controller.
owing to adopting technique scheme, compared with prior art, the utility model principle is simple, easy to operate, can obtain in advance the place ahead pedestrian contour information, fast with respect to vehicle position and pedestrian's walking, digital signal processor DSP compares to determine whether be pedestrian with the pedestrian contour information of storage after obtaining pedestrian contour information, then according to self-propelled vehicle self speed and pedestrian's correlation circumstance, contrast, if dangerous, when giving a warning to chaufeur, driver assistance is braked in advance, has improved the safety that trap for automobile travels.

The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
embodiment of the present utility model: a kind of pedestrains safety detects and prior-warning device, as shown in Figure 1: comprise self-propelled vehicle 1, at self-propelled vehicle 1 front end, be provided with pedestrian detection device 2, phonetic alarm device 3 is arranged on the interior driver of self-propelled vehicle 1 position, auxiliary brake 4 is connected with self-propelled vehicle 1 brake gear, core controller 5 is arranged in self-propelled vehicle 1, wherein pedestrian detection device 2 is connected with the input end of core controller 5, the mouth of core controller 5 is connected with phonetic alarm device 3 with auxiliary brake 4, 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 self-propelled vehicle 1 head light is consistent, auxiliary brake 4 comprises magnetoelectricity switch and magnetoelectricity on off controller.
the concrete principle of implementing
as shown in Figures 2 and 3: when being arranged on the CCD camera of self-propelled vehicle front end, scanning the place ahead and have pedestrian, and in pedestrian's related data (pedestrian contour, with respect to vehicle position and pedestrian's speed of travel) input dsp processor, dsp processor is comprehensively analyzed according to power actuated vehicle its data (moving velocity and self-position) and pedestrian's related data, judge that whether the place ahead is people and dangerous accident whether, if dangerous, opening voice is reported to the police and complemental brake system starts assistance driver braking.
