Problems solved by technology
Some existing traffic control systems are usually pre-set by humans, and cannot intelligently adjust the indication time of signal lights according to the number of vehicles on the road. In some areas, the method of embedding inductance coils on the ground is used to detect vehicles, but this This method has caused an increase in cost, and it is also easy to cause damage to the road surface

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] like Figure 1 to Figure 2 As shown, a traffic signal management and control system includes a controller that controls the start and stop of traffic lights and an image collector that is connected to the controller and is installed above the traffic intersection. What is used in this embodiment is a digital camera, and the system also includes painting on the road surface. The yellow detection strip 2 on 1, the detection strip 2 is a straight line, its direction is perpendicular to the direction of the road, and the distance between each detection strip is equal. Before the green light turns on, the image collector collects static images of the road surface. The lens at the front of the image collector is provided with a horizontal scale line, so that there is a scale line 4 in the collected static image. The controller analyze...

The invention discloses a traffic signal control system which comprises a controller for controlling the start / stop of a traffic light, an image acquisition unit which is erected above a traffic intersection and is connected with the controller, and a detection bar painted on a road surface, wherein the image acquisition unit is provided with a camera cleaning device, and comprises a buckle provided with an arc-shaped bayonet; the lower part of the buckle is provided with a containing groove; one end of the containing groove is provided with an opening; a shielding cover is arranged in the opening; both sides of the bottom of the shielding cover extend outwards, so that a first rotating shaft is formed; the two ends of the first rotating shaft extend into holes in the two side walls of the containing groove; a snap ring is welded on the inner side of the side wall of the containing groove; one end of a first spring is connected with the shielding cover, and the other end of the first spring is connected with the snap ring. The traffic condition on the road is analyzed in real time by adopting acquired pictures, and traffic control is adjusted intelligently. The cleaning device can be arranged on the body of a camera, and a glass baffle plate on the front part of the camera is cleaned regularly or unregularly, so that the working efficiency is improved.
Description
[0001] The present invention is a divisional application of the invention patent application with the application number 2012104285538, the application date is October 31, 2012, and the title is "a traffic signal management and control system". technical field [0002] The invention relates to a control system. Background technique [0003] As the number of vehicles in cities increases year by year, the control of traffic signals becomes a hot research topic. Some existing traffic control systems are usually pre-set by humans, and cannot intelligently adjust the indication time of signal lights according to the number of vehicles on the road. In some areas, the method of embedding inductance coils on the ground is used to detect vehicles, but this This method has caused the increase of cost, also easily causes the damage of road surface simultaneously. Contents of the invention [0004] The purpose of the present invention is to provide a traffic signal management and ...
