While, the problem such as the vehicle accident increase that the reversing produced therewith is difficult, reversing causes highlights the most day by day.This is rapid current
The vehicle accidents such as in the epoch of development, traffic blocks up day by day, the side swipe between the vehicle in traveling, between car and pedestrian and barrier
Frequently occur.Reversing becomes one of the most worried thing of driver, even driving experience is own through the abundantest department
Machine is also felt to move backward and is expended very much spirit.
Data statistics is had to point out, if the pre-reaction of the many half seconds of driver can be given before unsafe condition will occur
If between, then the mutual rear-end collision of automobile can reduce 30%, road traffic accident can reduce 50%, vehicle head-on collision accident
60% etc. can be reduced.Therefore for this stubborn problem, improve the difficulty run into when driver moves backward and closed by more people
Note, the manipulation convenience of automobile is had higher requirement by people, when thirsting for very much having a kind of device to can solve the problem that reversing to
The inconvenience that driver and pedestrian cause, reduces the many unsafe factors in driving, finally can be by accurate for vehicle fast and easy
Dock to regulation parking stall, reduce vehicle accident incidence rate.

Beneficial effects of the present invention: the present invention uses supersonic sounding to combine DSP intelligent control technology, it is provided that a kind of ultrasonic
Range finding astern controls, this device utilizes ultrasonic sensor detection reversing automobile and the distance of barrier and at liquid crystal display
Showing on device, alarm sends different audio alarms according to different distances simultaneously, and driver can be reminded to make standard
Really fast and easy operation, reduces the incidence rate of vehicle accident.
Accompanying drawing explanation
Fig. 1 is that the present invention controls principle of device block diagram.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
When being embodied as, in conjunction with Fig. 1, a kind of supersonic sounding astern controls, including controller 1, ultrasonic emitting mould
Block 2, ultrasound wave receiver module 3, ultrasonic sensor 4, photographing module 5, reverse gear sensor 6, alarm 7, display 8, CAN are total
Line 9, temperature compensation module 10.Ultrasonic emitting module 2, ultrasound wave receiver module 3, photographing module 5, reverse gear sensor 6, warning
Device 7, display 8, CAN 9, temperature compensation module 10 are that the peripheral circuit of controller 1 is connected with controller 1 respectively.Ultrasonic
Wave sensor 4 is connected with ultrasonic emitting module 2, ultrasound wave receiver module 3 respectively.
Controller 1 is the core of supersonic sounding astern controls, and controller 1 can be digital signal processor (DSP),
DSP can be DSP be TMS320C28335.Ultrasonic emitting module 2, ultrasound wave receiver module 3 are respectively intended to launch or receive
Ultrasonic signal.In order to improve the accuracy of supersonic sounding, ultrasonic sensor 4 has more than 2, and ultrasonic sensor is preferably formed with
6,4 ultrasonic sensors are wherein had to be evenly distributed on the dead astern of automobile, other 2 left backs being respectively distributed to automobile
And right back.Although the distance of driver's energy perception car and below barrier, but the situation that understanding that can not be definite is below, for
Solve this problem, after car, increase photographing module 5, by display 8 output image information, in order to make driver more preferable
Understand the situation of blind area.The operation signal that reverses gear can be obtained by reverse gear sensor 6.Alarm 7 is used for sending audio alarm, should
Controlling device and can be less than 120cm at barrier away from ultrasonic sensor, alarm starts to pipe, and sends interruption tone low；
When barrier away from ultrasonic sensor less than 80cm, alarm sends rapid interruption tone；When barrier is away from ultrasonic sensor
