Below with reference to accompanying drawings the present invention is robbed the vehicle peccancy behavioral value system of row left-hand lane
Embodiment be described in detail.
Usually, at bigger current crossing, the track of setting include turn lane, left-hand lane,
Through Lane and right-hand lane, tune track carries out Turning travel for the vehicle adjusting travel direction,
Left-hand lane is turned left curved moving ahead for vehicle, and right-hand lane is turned right curved moving ahead for vehicle, Through Lane
Keep straight on to dead ahead for vehicle.Correspondingly, can arrange at such current crossing and include multiple signal
The signal lights instruction equipment of lamp subelement, driver must be led to according to the instruction of signal lights instruction equipment
OK, the behavior of the instruction of violation signal lamp instruction equipment is all decided to be act of violating regulations.
Wherein, considering based on traffic efficiency, control of traffic and road department does not arranges correspondence for right-hand lane
Signal lights subelement, after the signal lights subelement that Through Lane is corresponding reddens, left-hand lane is corresponding
Signal lights subelement turns green immediately, simultaneously as through vehicles is generally many than turning left curved vehicle, so
The green time of signal lights subelement corresponding to left-hand lane arranged is shorter, and the Through Lane arranged
The green time of corresponding signal lights subelement is longer.Such signal lights design is rational,
But also there will be special circumstances when real road passes through, such as in front craspedodrome regional traffic control or
Peak period on and off duty, owing to selecting the most predetermined the fewest of curved vehicle that turn left, also result in a left side
Excessive inventory for the vehicle of the lamps such as track, side, and at this moment, some drivers can select to travel at Through Lane,
And leave Through Lane dead line immediately after the signal lights subelement that Through Lane is corresponding reddens, switch to
The left-hand lane of green light continues to travel.
The every trade of robbing of above-mentioned driver is to have bigger hazardness, has not only broken up normal traffic order
Sequence, causes the current unfairness of traffic intersection, and robs row and easily cause accident.Thus, detect this
Robbing every trade is to be necessary, but currently lacks such inspection equipment, and control of traffic and road department can
Can just use when road congestion the mode of manual detection that regulations vehicle is punished, this is broken rules and regulations

The present invention has built a kind of vehicle peccancy behavioral value system robbing row left-hand lane, described detection
System by the joint operation of multiple electromagnetic induction devices, combine judgement, determine in left-hand lane to be green
Lamp pass through state time whether there is Through Lane and rob the vehicles peccancy that row left-hand lane is current, solve with
Easily rob the difficult problem acting event toward the ineffective traffic intersection brought of detection, ensured that traffic intersection passes through
Fairness.

It addition, FPGA (Field-Programmable Gate Array), i.e. field-programmable gate array
Row, he is the product of development further on the basis of the programming devices such as PAL, GAL, CPLD,
Being to occur as a kind of semi-custom circuit in special IC (ASIC) field, he solves
The deficiency of custom circuit, also overcomes the shortcoming that original programming device gate circuit number is limited.
As far back as 1980 mid-nineties 90s, FPGA takes root in PLD equipment.CPLD and FPGA
Include the Programmadle logic unit of some relatively large amount.The density of CPLD gate arrives thousand of
Between several ten thousand logical blocks, and FPGA is typically several ten thousand to millions of.CPLD and FPGA
The main distinction be their system structure.CPLD is a somewhat restrictive structure.This knot
Structure is arranged by the logical groups of one or more editable result sum and the locking of some relatively small amounts
Depositor composition.Such result be a lack of edit motility, but but have it is anticipated that delay
Time and the logical block advantage to connecting unit height ratio.And FPGA is to have a lot of connection lists
Unit, although so allowing him edit more flexibly, but structure is complicated many.CPLD and
The difference of FPGA another one is that most FPGA contains high-level built-in module (such as addition
Device and multiplier) and built-in memory body.Therefore a relevant important difference is the newest FPGA
Support to reconfigure completely or in the system of part.Allow their design along with system upgrade or
Person dynamically reconfigures and changes.Some FPGA can allow a part for equipment update and other
Part continues properly functioning.
FPGA have employed logical cell array LCA (Logic Cell Array) such a concept,
Inside includes configurable logic blocks CLB (Configurable Logic Block), input and output mould
Block IOB (Input Output Block) and three parts of interconnector (Interconnect).
Field programmable gate array (FPGA) is programming device, with conventional logic circuit and gate array
Row (such as PAL, GAL and CPLD device) are compared, and FPGA has different structures.FPGA
Utilizing small-sized look-up table (16 × 1RAM) to realize combination logic, each look-up table is connected to one
The input of d type flip flop, trigger drives other logic circuits again or drives I/O, thus constituting
Not only can realize combination logic function but also the basic logic unit module of sequential logic function can be realized, this
A little intermodules utilize metal connecting line interconnect or be connected to I/O module.
Use the vehicle peccancy behavioral value system robbing row left-hand lane of the present invention, for existing detection
The detection mode robbing row left-hand lane excessively lays particular stress on the technology that manual detection, detection time and dynamics are inadequate
Problem, by road communication crossing Rational Arrangement detection equipment, it is achieved rob row left-hand lane vehicle
Effectively detection, image processing techniques and wireless communication technology improve this detection system the most targetedly
The intelligence degree of system.
