Description
Technical field
The present invention relates to traffic monitoring field, particularly relate to a kind of be positioned at traffic intersection across solid line road
Vehicle identification method.
Background technology
The act of violating regulations of automobile driver is detected and is concentrated mainly on two aspects by prior art, one
Whether aspect is whether the passing rules that traffic signal violation lamp is corresponding, such as, if make a dash across the red light, rush
Green light and whether cross driving dead line etc., on the other hand concentrates on vehicle interior personnel's act of violating regulations
Detection, for example whether wear safety belt, whether look after children and just sit back and wait in copilot.But, for
Driver vehicle but lacks effective detection method at traffic intersection across the act of violating regulations of solid line,
It practice, above-mentioned act of violating regulations because upset travel order, run counter to road traffic travel fairness,
Easily cause major accident because trying to be the first and have more hazardness.
In prior art, the vehicle to traffic intersection still uses backward across the detection of solid line behavior
Manual detection mode, i.e. arranges a traffic-police at each traffic intersection, and timing is to through traffic
Each vehicle at crossing carries out naked eyes identification, has driven to solid line region but still next being found to have vehicle
When switchback is changed trains, the number-plate number of go forward immediately inquiry registered vehicle information, such as vehicles peccancy,
Realize the punishment to vehicles peccancy driver.Obviously, this detection mode excessively depends on manually, its
Efficiency and accuracy are greatly affected.At present, still there is no corresponding effective electron detection means.
Accordingly, it would be desirable to a kind of be positioned at traffic intersection across solid line road vehicle identification method, it is possible to by institute
State identification system and set up at monitored traffic intersection, use detection of electrons means automatically to identify have car
Across the vehicles peccancy of solid line behavior and corresponding license board information, it is to avoid manual intervention, improve and know
Other accuracy and real-time.

SCM single-chip microcomputer is all 8 or 4.The most most successful is the 8051 of INTEL, hereafter exists
MCS51 Series MCU system has been developed on 8051.Single Chip Microcomputer (SCM) system based on this system is straight
The most also it is being widely used.The raising required along with industrial control field, starts to occur in that 16
Single-chip microcomputer, but be widely applied the most very much because cost performance is undesirable.Along with consumption after the nineties
Electronic product develops on a large scale, and singlechip technology has obtained huge raising.Along with INTEL i960 series especially
Being that the extensive of ARM series later is applied, 32 single-chip microcomputers replace rapidly the height of 16 single-chip microcomputers
End status, and enter mainstream market.And the performance of traditional 8 single-chip microcomputers have also been obtained and rapidly carries
Height, disposal ability improves hundreds times compared with the eighties.32 high-end Soc single-chip microcomputer dominant frequency are
Through more than 300MHz, performance directly chases after the application specific processor of the mid-90, and common model is dispatched from the factory
Price falling is to 1 dollar, and the model of most significant end also only has 10 dollars.
Single Chip Microcomputer (SCM) system was the most only developed under bare machine environment and used the present age, and the most special is embedding
Enter formula operating system to be widely used on the single-chip microcomputer of complete series.And as palm PC and mobile phone
The high-end single-chip microcomputer of core processing even can directly use special Windows and Linux to operate system
System.
