Description
Technical field
The present invention relates to technical field of traffic signal control more particularly to a kind of intelligent traffic signal control system and its controls
Method processed.
Background technique
With the development of economy with the raising of living standards of the people, automobile increasingly near-earth walks close to people's lives, therewith
And the importance of the intelligent transportation such as traffic lights regulation come is increasingly enhanced.Traditional traffic signal lamp system is nearly all setting
The passage of fixed time interval control vehicle, it is difficult to adapt to road conditions complicated and changeable, and current adaptive traffic lights algorithm
Complexity is generally basede on data and needs accuracy after the smoothing processing based on 15 minutes just sufficiently high, and real-time is poor.Meanwhile certain
One trade road ahead congestion, continue the trade vehicle can not when driving, if traffic lights still normally switch, each trade vehicle
It will continue to drive into congestion trade, entire crossing blocked until being accumulate to crossing, influences other trade normal pass, or even lead
Cause the serious consequences such as traffic paralysis.
To solve the above-mentioned problems, a kind of invention is disclosed in existing invention, application No. is CN201410259827.4, names
Referred to as real-time intelligent traffic signal lamp control system and method based on geomagnetic sensor.
Although solving the problems, such as that same trade vehicle is deposited in crossing in the prior art, other trade vehicles can not be prevented
Drive into, at the same the installation of geomagnetic sensor still can road pavement cause adverse effect.
Summary of the invention
The purpose of the present invention is in view of the deficienciess of the prior art, provide a kind of intelligent traffic signal control system and its
Control method.
To achieve the goals above, a kind of technical solution that intelligent traffic signal control system is taken of the present invention is as follows:
A kind of intelligent traffic signal control system, the controller including signal lamp and control signal lamp cycle variation, institute
Stating signal lamp is three-dimensional arrow signal lamp, and the signal lamp rear is additionally provided with ultrasonic range finder, the ultrasonic range finder
Measured range data is simultaneously passed to controller, the controller by real time detection signal lamp rear fixed area vehicle condition
Signal lamp is controlled by red greenish-yellow sequence periodic cycle variation, wherein controller is according to the ultrasonic range finder transmitting received
Data control the pause of corresponding signal lamp by red greening, and during which controller controls time and the sequence of other signal lamp cycles variation
It is constant.Controller judges whether corresponding region has stoppage of vehicle according to the data variation that ultrasonic range finder transmits, and has vehicle
Stop then judges abnormal while suspending corresponding signal lamp by the process of red greening, and controller receives super after vehicle disappears
When the data of sound-ranging equipment transmitting enter normal signal lamp periodic cycle or corresponding signal lamp green light after restoring normal 3 seconds
Between terminate enter subsequent periodic recycle, during which signal lamp cycle circulation do not stop.
The signal lamp includes upper signal lamp, lower signal lamp, left signal lamp and right signal lamp, and place trade respectively corresponds
For upper trade, lower trade, left lateral road and right track, the ultrasonic range finder for being set to signal lamp rear is respectively corresponded as upper ranging
Instrument, lower rangefinder, left rangefinder and right rangefinder, the monitored region of ultrasonic range finder respectively correspond for upper region, lower region,
Left region and right region.There is vehicle congestion stop in upper region, and then upper rangefinder institute measured data changes, and it is different that controller receives this
Upper signal lamp, left signal lamp and the corresponding turn signal pause of right signal lamp are controlled after regular data by the process of red greening, after prevention
Continuous vehicle drives into trade congestion regions, and lower region, left region and right region have vehicle congestion to stop the then corresponding letter of controller control
Signal lamp suspends the process by red greening, and subsequent vehicle is prevented to drive into congestion trade.
According to a kind of a kind of above-mentioned intelligent traffic signal control method of intelligent traffic signal control system, including following step
It is rapid:
Step 1: upper rangefinder, lower rangefinder, left rangefinder and right rangefinder monitor upper region, lower region, a left side respectively
Range data information when region and right region have no occluder, and controller is passed data to, the controller data information is
Nominal reference data, enter step two；
Step 2: controller presets the periodicity of signal lamp, lower signal lamp, left signal lamp and the variation of right signal lamp
Circulation, enters step three；
Step 3: going up rangefinder, lower rangefinder, left rangefinder and right rangefinder, respectively region, lower area in real-time monitoring
The range data information in domain, left region and right region, and controller is passed data to, enter step four；
Step 4: controller judges that exception then enters step five according to the data and nominal reference data comparison received,
Judgement normally then enters step six；
Step 5: the data exception of upper rangefinder then suspends the straight trip lamp of upper signal lamp, the right-hand rotation lamp of left signal lamp and the right side
Process of the left-hand rotation lamp of signal lamp by red greening, straight trip lamp, the left signal of signal lamp under the data exception of lower rangefinder is then suspended
For the right-hand rotation lamp of the left-hand rotation lamp of lamp and right signal lamp by the process of red greening, the data exception of left rangefinder then suspends left signal lamp
The right-hand rotation lamp of straight trip lamp, the left-hand rotation lamp of upper signal lamp and lower signal lamp is by the process of red greening, and the data exception of right rangefinder is then
Suspend the left-hand rotation lamp of the straight trip lamp of right signal lamp, the right-hand rotation lamp of upper signal lamp and lower signal lamp by the process of red greening, during which controls
Device processed controls other signal lamps and recycles progress by normal periodic, until the data of the upper rangefinder received are restored normal 3 seconds
Enter subsequent periodic after entering normal periodic circulation or corresponding signal lamp green time afterwards to recycle, multiple rangefinders
Data it is abnormal simultaneously when suspend corresponding signal lamp by the process of red greening simultaneously, enter step four；
Step 6: controller controls upper signal lamp, lower signal lamp, left signal lamp and the right side by preset periodic cycle
Signal lamp cycle variation, enters step four.
Compared with prior art, the invention has the benefit that easy for installation and road pavement avoids trade congestion without influence
When subsequent vehicle pour in block crossing the case where.
