Abstract
The present invention proposes a kind of highway barrier system for prompting, system includes acoustic emission module, real-time speed detection module, processing module and prompting module, acoustic emission module launches forward sound wave, processing module includes acoustic receiver module, computing module and comparison module, acoustic emission module and sound wave receiving module are engaged, acoustic receiver module, which receives, to be run into the sound wave that barrier reflects and sends the time difference among this to computing module, real-time speed detection module detects real-time speed when vehicle travels and sends real-time speed to computing module, computing module calculates the real-time range of obstacle distance vehicle according to time difference and real-time speed and sends real-time separation to comparison module, comparison module is by real-time range compared with safe distance, prompting module sends safety alarm at once if safe distance is less than.Highway barrier system for prompting of the present invention sends alarm, detection in real time is effectively improved the safety coefficient during driver's traveling, reduces the probability of accident generation in the case of there is barrier in front by sound ranging to driver.
Description
Technical field
The present invention relates to a kind of system for prompting, and in particular to a kind of highway barrier system for prompting.
Background technology
With the development of traffic, automobile has been obtained for very extensive application, becomes the important of people's go off daily
Walking-replacing tool.But the factor such as prolonged driving, vehicle blind zone or weather environment can all reduce the reaction speed of driver
Degree, causes potential safety hazard, when particularly occurring barrier suddenly in front or run at high speed.
Therefore, in view of the above-mentioned problems, the present invention proposes a kind of new technical scheme.
The content of the invention
It is an object of the invention to provide a kind of highway barrier system for prompting.
The present invention is achieved through the following technical solutions：
A kind of highway barrier system for prompting, the system include acoustic emission module, real-time speed detection module, processing module
And prompting module, the acoustic emission module launch forward sound wave, the processing module includes acoustic receiver module, computing module
And comparison module, the acoustic emission module and sound wave receiving module are engaged, the acoustic receiver module, which receives, runs into obstacle
Sound wave that thing reflects simultaneously sends time difference among this to computing module, and the real-time speed detection module detects vehicle
Real-time speed during traveling simultaneously sends real-time speed to computing module, and the computing module is according to time difference and real-time speed meter
Calculate the real-time range of obstacle distance vehicle and send real-time separation to comparison module, the comparison module is by real-time range
The prompting module sends safety alarm at once compared with safe distance, if safe distance is less than.
Further, the acoustic emission module is ultrasonic transmitter.
Further, the safety alarm that the prompting module is sent is audible alarm, light alarm or vibrations alarm.
Further, the system whole operation during vehicle movement.
The beneficial effects of the invention are as follows：Highway barrier system for prompting of the present invention is hindered by sound ranging in front
Alarm is sent to driver in the case of hindering thing, detection in real time is effectively improved the safety during driver's traveling
Coefficient, reduce the probability of accident generation.

Receive and run into the sound wave that barrier reflects and send the time difference 5 among this to computing module 32, real-time speed detection
Real-time speed 6 when module 2 detects vehicle traveling simultaneously sends real-time speed 6 to computing module 32, computing module 32 according to when
Between poor 5 calculate the real-time range 7 of obstacle distance vehicle and send real-time separation 7 to comparison module 33 with real-time speed 6,
By real-time range 7, the horse back of prompting module 4 sends safe police to comparison module 33 compared with safe distance, if safe distance is less than
Report.
In the present embodiment, acoustic emission module 1 is ultrasonic transmitter.
In the present embodiment, the safety alarm that prompting module 4 is sent is audible alarm, light alarm or vibrations alarm.
In the present embodiment, system whole operation during vehicle movement.
Highway barrier system for prompting of the present invention is by sound ranging, to driver in the case of there is barrier in front
Alarm is sent, detection in real time is effectively improved the safety coefficient during driver's traveling, reduces accident
Probability.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
