Description

A kind of new vehicle automatic segmentation speed limit solution
Technical field
The present invention relates to technical fields, more particularly to.
Background technique
Created with this year, modified highway, national highway and international road increase again, alleviate traffic significantly Pressure accelerates vehicular circulation speed, improves carrying capacity.However the whole promotion of road conditions really brings another and asks Topic, overspeed of vehicle problem, it is a large amount of facts proved that, high way super speed traveling be major traffic accidents chief reason it One, therefrom caused by casualties and property loss it is even more startling.Overspeed of vehicle oversight mechanism, can be to exeeding the regulation speed The certain deterrent effect of driver adds point penalty with economic penalties, revokes the modes such as driving license, driver is forced to advise in accordance with traffic Then, the incidence of accident can be reduced to a certain extent.
At present for the behavior that exceeds the speed limit, the instant warp usually reported by vehicle monitoring platform according to automobile wireless monitor terminal Latitude extracts the speed limit value of current road segment, then the instantaneous velocity reported with automobile wireless monitor terminal compares, to judge vehicle Whether overspeed condition is in.When vehicle reaches speed limit value, vehicle monitoring platform issues suggestion voice and monitors eventually to automobile wireless End, remind driver exceeded the speed limit, and by vehicle monitoring platform count hypervelocity information after, driver is punished accordingly.This prison Prosecutor formula has certain problems, due to automobile wireless terminal upload vehicle instant longitude and latitude and speed during often Certain delay and loss are had, will lead to vehicle monitoring platform in this way can not judge immediately whether vehicle is in overspeed condition.
Therefore, how to provide one kind can solve large-sized truck, oil carrier, and engineering truck bring due to hypervelocity is hidden safely Suffer from, company fleet's standardized administration, management level will not bring traffic deduction of points fine and a system such as be tired of brain due to overspeed of vehicle everyday The problem of new vehicle automatic segmentation speed limit solution of column problem is those skilled in the art's urgent need to resolve.
Summary of the invention
In view of this, the present invention provides one kind to have automatic precisely speed limit, specification driver operation, reduction accident rate, goes The new vehicle automatic segmentation speed limit solution of the features such as except security risk.
To achieve the above object, the invention provides the following technical scheme:
The program includes that there are three types of implementations: API Calls map pinpoints speed limit and tests the speed: by API Calls map speed limit point And the speed limit value in speed limit region;Radar detection: pass through the speed limit value in electronic radar detection front;Image recognition technology: pass through figure As identification, identification front speed limitation board;Above-mentioned three kinds of modes include following device:
MCU system: analysis comparison is carried out to the data received, determines speed limit value;
Power module part: the power supply of each module is provided;
API map interface: the speed limit value and region speed limit value of the different fixed points in map datum are taken out;
The mode of invocation map speed limit value:
(1) it constantly transfers online, current latest GPS is uploaded by equipment and is disobeyed degree according to server is arrived, by server on ground Current road segment speed limit value is obtained on figure, then remote transmission gives equipment processing;
(2) it constantly transfers offline, by running navigation map mode on device systems, map is offline downloading map, is passed through Constantly anchor point obtains map speed limit value to system GPS;
Radar module: by radar detection mode, fixation speed limit point and the flowing speed limit in front etc. are detected;
Image character identification: the speed limitation board character in front is handled;
Voice module prompt: current speed limit value is prompted to broadcast;
GPS module: for testing the speed, constantly position is positioned;
Gsm module: for all data of uploading device and location data etc.;It can receive what server end returned simultaneously Speed limit value;
Speed limit actuator: for forcing Control for Speed Limitation, the current maximum speed of vehicle is limited.
Preferably, in a kind of above-mentioned new vehicle automatic segmentation speed limit solution, the concrete operation method of mode 1 Are as follows: using map datum fixed point speed limit and fixed point measurement data, by API map interface by data access MCU system;That is: I Call the api interface of up-to-date map to carry out the speed limit point and region speed limit point of identification different sections of highway, by MCU system to receiving API data carry out processing analysis so that it is determined that current road segment maximum speed limit value, then issue instruction for determining speed limit value It is sent to speed-limiting device, reaches automatic speed-limiting.
Preferably, in a kind of above-mentioned new vehicle automatic segmentation speed limit solution, the concrete operation method of mode 2 Are as follows: the data detected can be introduced by radar detection when the fixation speed limit point of radar detection to front and flowing speed limit Analysis comparison is carried out in MCU system so that it is determined that speed limit value, then issues instructions to speed-limiting device, to reach automatic speed-limiting.
Preferably, in a kind of above-mentioned new vehicle automatic segmentation speed limit solution, 3 concrete operation method of mode are as follows: Image recognition technology: one camera is installed in the front of vehicle, by image recognition technology algorithm, by the road speed limitation board in front Speed limit value on son is identified, the data recognized are then transferred back to MCU system and carry out processing analysis, reach different sections of highway Speed limit.
It can be seen via above technical scheme that compared with prior art, the invention has the advantages that energy intelligent recognition is not gone the same way The speed limit value of section, (1) pass through API Calls map speed limit point and the speed limit value in speed limit region;(2) front is detected by electronic radar Speed limit value;(3) pass through image recognition, identification front speed limitation board;Three of the above mode is constantly compared, and MCU detects two A speed limit value can just execute speed limit when identical, reach the accurate speed limit of highest, be not in accidentally speed limit;In addition to this, the present invention is gone back After being handled by MCU, issues speed limit and instruct to speed-limiting device, reach automatic speed-limiting, can control the braking system of vehicle, driver It can not drive over the speed limit.
