Abstract
The invention discloses a traffic signal controller. The traffic signal controller comprises a control module and an image collector, wherein the control module is used for controlling traffic lights to be turned on or turned off, and the image collector is erected above a traffic intersection and is connected with the controller. The traffic signal controller is characterized in that the system also comprises detection strips painted on a road surface, the image collector is used for collecting static images on the road surface and horizontally parting off the static images before a green light is turned on, and the control module is used for judging the length of vehicles on the road according to the initial position of the detection strips in the images collected by the image collector, which continuously occurs on a horizontal parting line. The traffic signal controller is used for analyzing traffic conditions on the road in real time by adopting the collected images and makes intelligent adjustment on traffic control; and simultaneously the two detection strips having no damage to the road are used as detection reference substances, and therefore, the processing requirement for the controller is reduced, the cost is low, and the implementation is easy.
Description
Technical field
The present invention relates to a kind of control system.
Background technology
Along with the vehicle increase year after year in city, the control of traffic signals becomes the heat subject of a research.The normally artificial setting in advance of existing some traffic control system, can not how much come the instruction time of intelligent conditioning signal lamp along with the vehicle on road, also some area adopts the method for burying on the ground telefault underground to detect vehicle, but this kind of method caused the increase of cost, also easily cause the infringement on road surface simultaneously.
Summary of the invention
The object of this invention is to provide and a kind ofly can automatically according to the number of vehicle, to signal lamp, carry out the traffic signal control of Based Intelligent Control.
To achieve these goals, by the following technical solutions: a kind of traffic signal control, comprise that controlling traffic lights starts the control module stopping and the image acquisition device being connected with controller that is erected at traffic intersection top, it is characterized in that: described system also comprises the detector bar whitewashing on road surface, before green light lights, image acquisition device gathers road surface still image, static image is carried out to level and cut apart, control module appears at according to detector bar in the image of image acquisition device collection the length that reference position on horizontal cut-off rule judges vehicle on road continuously; If capped length exceeds designated value, increase the green light opening time of next time on this road, reduce the red light opening time simultaneously; If capped length is less than designated value, reduce the green light opening time on this road next time, increase the red light opening time simultaneously;
Described detector bar is straight line, and its trend is vertical with the trend of road, and the spacing between each detector bar equates.
Described image acquisition device is camera or camera.
The present invention adopts the traffic on the picture real-time analysis road of collection, and traffic control is made to adjustment, adopts the detector bar that does not injure road as detecting object of reference simultaneously, has reduced the processing requirements to controller, and cost is lower, is easy to realize.

Traffic schematic diagram on Tu1Wei road;
Fig. 2 is the picture that video camera is taken;
Fig. 3 is the structural representation of detector bar;
Fig. 4 is the left view of Fig. 3;
Fig. 5 is another structural representation of detector bar.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1 to Figure 2, a kind of traffic signal control, comprise that controlling traffic lights starts the controller stopping and the image acquisition device being connected with control module that is erected at traffic intersection top, what in this embodiment, adopt is digital camera, system also comprises the yellow detector bar 2 whitewashing on road surface 1, detector bar 2 is straight line, and its trend is vertical with the trend of road, and the spacing between each detector bar equates.Before green light lights, image acquisition device gathers road surface still image, image transmitting to control module after, control module is carried out level to image and is cut apart, as shown in Figure 2, cut-off rule 4 is divided equally picture, and the length being covered continuously by detector bar judges waiting for vehicle 3 quantity by crossing, if capped length exceeds designated value, increases green light opening time on this road next time, reduces the red light opening time simultaneously; If capped length is less than designated value, reduce the green light opening time on this road next time, increase the red light opening time simultaneously.The capped length of detector bar can directly be read by cut-off rule, has reduced the time that control module is processed image, has reduced the requirement of control module.
As shown in Figure 3 and Figure 4, wherein detector bar is for being obliquely installed, and its upper surface tilts to intersection of roads, and upper surface is provided with rhone, rhone is divided into two kinds, and a kind of is rhone longitudinally, another kind is to be provided with horizontal rhone in the bottom of detector bar, and the back side of detector bar is arcwall face.One of inclination facing to digital camera like this, can be so that camera obtain comparatively the significantly image of detector bar, meanwhile, the rhone on detector bar both can draining, can increase the diffuse reflection of detector bar again, the arc at the back side has reduced the damage to vehicle tyre.Certainly, as shown in Figure 5, the rhone arranging on detector bar also can be for being obliquely installed.As other distortion, can be also latticed rhone, like this draining and irreflexive better effects if.
Claims (3)
1. a traffic signal control, comprise that controlling traffic lights starts the control module stopping and the image acquisition device being connected with controller that is erected at traffic intersection top, it is characterized in that: described traffic signal control also comprises the detector bar whitewashing on road surface, before green light lights, image acquisition device gathers road surface still image, static image is carried out to level and cut apart, control module appears at according to detector bar in the image of image acquisition device collection the length that reference position on horizontal cut-off rule judges vehicle on road continuously; If capped length exceeds designated value, increase the green light opening time of next time on this road, reduce the red light opening time simultaneously; If capped length is less than designated value, reduce the green light opening time on this road next time, increase the red light opening time simultaneously, wherein detector bar is for being obliquely installed, its upper surface tilts to intersection of roads, and upper surface is provided with rhone, the bottom of detector bar is provided with horizontal rhone, and the back side of detector bar is arcwall face.
2. traffic signal control as claimed in claim 1, is characterized in that: described detector bar is straight line, and its trend is vertical with the trend of road, and the spacing between each detector bar equates.
3. traffic signal control as claimed in claim 2, is characterized in that: described image acquisition device is camera or camera.
