Description of the drawings
Fig. 1 shows the structured flowchart of the rearview mirror drive recorder of the present invention.
Specific embodiment
As shown in figure 1, rearview mirror drive recorder includes that MCU or ARM as controller, two groups of different resolutions take the photograph
As the head, display screen for being integrated in rearview mirror, condenser type vibrating sensor, solid state hard disc, GPS module, loudspeaker, microphone, infrared
Line range finder module and communication module, the driving video of the solid state hard disc storage video acquisition device collection and microphone collection
Audio-frequency information, the positional information of the GPS module collection vehicle, vibration that the vibrating sensor collection vehicle is subject to letter
Number, the range information of the infrared distance measuring module collection vehicle and vehicle body surrounding objects, the communication module is used for and other
The rearview mirror drive recorder is communicated with sending accident video information during vehicle generation accident and from other institutes
The accident video information during rearview mirror drive recorder acquisition vehicle generation accident is stated, the display screen plays corresponding accident
Video information.Each group of described camera is arranged at the diverse location of vehicle body, with collection vehicle left front, right and left,
The video information in right front, right back and dead astern.
The operation principle of rearview mirror drive recorder of the present invention is：When driving, controller controls two groups first
One group of camera that the camera intermediate-resolution of different resolution is relatively low is opened, and then monitors other possibility around vehicle and vehicle body
The distance between barrier or vehicle of generation accident.
Multigroup infrared ranging transceivers, be respectively set on vehicle body just before, just behind, left surface, right flank, a left side
Anterior angle, left rear corner, right anterior angle and right relief angle, for measuring immediately ahead of vehicle body, dead astern, left side, right side, it is left front, left back, right before
The distance between with this eight orientation vehicles behind the right side and other barriers.Every group of infrared ranging transceivers include infrared emission list
Unit and infrared receiver and signal pre-processing circuit constitute, and signal pre-processing circuit includes amplifying circuit and A/D moduluss of conversion
Block.During work, launch infrared light wire harness from infrared emission unit to testee, the infrared light wire harness is Jing after testee reflection
Received by infrared receiver.Infrared light wire harness Jing signal pre-processing circuits after the reception are processed, and are carried to controller
For distance value.In the present embodiment, infrared ranging transceivers can adopt the GP2D02 infrared distance measuring sensors of Sharp Corp.
Controller judges whether described each distance value has at least one more than predetermined threshold value.The threshold value is, for example, 20m.Such as
Fruit is that then on the one hand controller cuts out that group of relatively low camera of above-mentioned resolution ratio and open that group of higher camera of resolution ratio
And condenser type vibrating sensor.So, only when accident may occurring, the higher video letter of ability acquisition resolution
Breath, so as to dramatically saves on the information content for needing memory storage.
On the other hand, controller opens microphone, gathers audio-frequency information and audio-frequency information is stored in solid state hard disc.Deposit
The video information for being stored accordingly is set up with audio-frequency information and is associated by Chu Shi, controller, for example, sets up video file and audio frequency
The corresponding relation of the filename of file, so that the audio-frequency information in solid state hard disc can correctly correspond to corresponding video letter
Breath.
When the vibration information that the condenser type vibrating sensor is detected exceeds default threshold value with above-mentioned distance value,
Then controller control loudspeaker send alarm, remind driver currently to there occurs collision accident.Vehicle location now is believed by GPS module
Breath and temporal information are broadcast to other the described rearview mirror drive recorders with communication module by communication module.Driving conditions
In, the communication module of vehicle itself also receives the position of the existing accident generation that other described rearview mirror drive recorders send
Information, temporal information and video information, when vehicle drives to the position that these existing accidents occur, controller is controlled point by force
One group of higher camera of resolution is opened, and while opening condenser type vibrating sensor and microphone, supervise to vibration information
Control.Once generation accident, the higher video information of the resolution ratio for collecting just are sent to above rheme by communication module and are put
Other in a range of region (for example, more than state positional information for the center of circle, the region that radius is 5 kilometers) that information determines
The communication module of vehicle, the same rearview mirror drive recorder for installing the present invention, in the rearview mirror for other described vehicles
Display screen play.During broadcasting, recent occurrence can first be played according to time sequencing therefore video information is with described in being supplied to
Other vehicles the newest early warning of driver.Meanwhile, the accident video information that described other vehicles send also is received, with to this
The driver of car provides newest early warning.
The technical scheme for being provided to the embodiment of the present invention above is described in detail, specific case used herein
The principle and embodiment of the embodiment of the present invention are set forth, the explanation of above example is only applicable to help and understands this
The principle of inventive embodiments；Simultaneously one of ordinary skill in the art, embodiments in accordance with the present invention, specific embodiment with
And will change in range of application, in sum, this specification content should not be construed as limiting the invention.
