Along with development of science and technology, have radar for backing car to sell on the market now, but such device generally is used on the car, and price is somewhat expensive more.And existing radar for backing car on the one hand since during reversing its effective alarm distance have only about 2.5 meters, for light weight, the well behaved vehicle of braking system may be effectively, but it is big for quality, the vehicle that the braking system performance is poor slightly, alarm distance are too near, also might have an accident.On the other hand, some existing radar for backing car does not provide tailstock video pictures basically, will cause the shape of driver to car and obstruction like this, size and kind ignorant, and the driver can not effectively hide car and obstruction, thereby causes traffic accident.
Summary of the invention
At defective or deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of vehicle backing rear-view mirror device, and this plant investment expense is low, stable performance, simple to operate, respond well.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of vehicle backing rear-view mirror device, comprise image collection module, two range finder modules, information analysis processing module, image display, alarm module and power modules, image collection module, two range finder modules are connected with the information analysis processing module respectively, the information analysis processing module also is connected with image display, alarm module respectively, and power module is respectively each module provides work required burning voltage.
Other technologies of the present utility model are characterized as:
Described two range finder modules are installed in the automobile tail both sides respectively, and image collection module is installed in the centre position of automobile tail, and it is indoor that image display, alarm module and information analysis processing module are installed in car steering.
Described image collection module adopts the colored low-light (level) automobile rearview camera of 120 ° of wide-angle CCD.
Described range finder module adopts two range radars, and two range radars are installed in the automobile tail both sides respectively, and horizontal forward backwards, and described radar range is 8 meters.
Described information analysis processing module adopts the MC9S12DSP512MAL single-chip microcomputer of Freescale company.
Described image display is the TFT LCD.
Described alarm module adopts the active buzzer of 12V.
Described power module adopts MIC29752BWT and MIC29310-5.0BT step-down chip.
Therefore, use the utlity model has following advantage:
(1) with low cost.Present stage, the similar rearview device for reverse price of selling on the market was basically all about 4000 yuan, and used the utility model, and expense is about 1500 yuan, and basically without any need for maintenance cost.
(2) simple to operate.During reversing, as long as the driver hangs up reverse gear, device starts automatically, starts working, push away reverse gear after, device is closed automatically.
(3) IMAQ is stable, the frame losing phenomenon can not occur, and the image clear display understands that range finding accurately and reliably.
(4) adaptive capacity is strong, and is applied widely.The utility model can waterproof, antifog, anti-mud, antidetonation, therefore both can be used for passenger cars such as car, also can be used for lorry and engineering vehicle.
(5) package unit stable performance, safe and reliable, durable in use.
