Abstract
The utility model provides a traffic light system which can perform intelligent management according to traffic flow, in particular to a traffic light system capable of automatically adjusting according to traffic flow, which comprises a main control circuit and traffic light indicating devices arranged at all intersections; particularly, each traffic light indicating device corresponds to a traffic flow detecting device; and the traffic flow detecting devices are communicated with the main control circuit. The traffic light system capable of automatically adjusting according to traffic flow additionally has a traffic flow detection function and an intelligent management function on the basis of the original traffic light system, which can significantly relieve intersection traffic pressure and improve traffic efficiency. In addition, the whole system also has the advantages of high efficiency, stability and the like.
Description
Technical field
The utility model relates to a kind of road traffic lamp system.
Background technology
In current society, traffic lights has become the most effective, the modal method of the vehicle that relieves traffic congestion, and is the indispensable part of each traffic intersection.But along with the progress of expanding economy, society, automobile quantity sharply increases, and urban transportation is day by day crowded.The drawback that conventional traffic light exists is exposed day by day also.Wherein control mode is too inflexible, and can not reach the best traffic efficiency of road is the most tangible problem.At present, the control method that the traffic lights in most of city adopts is: set the time-delay of a time control traffic lights, control traffic status in changeless mode.Yet in fact the vehicle flowrate chamber constantly changes, in different highway sections or the different time vehicle flowrate in same highway section very big-difference is all arranged.Such situation occurs so unavoidably: the vehicle flowrate of a certain direction is very big but to need to wait for red light, and the very little or empty road of other direction vehicle flowrate but gives a green light always.These phenomenons have not only reduced the traffic efficiency of road, also human and material resources are caused very big waste.
Summary of the invention
At shortcoming and drawback that current traffic lights exists, the utility model provides a kind of traffic light systems that can carry out intelligent management according to vehicle flowrate.
Take following technical scheme:
Can comprise governor circuit and the traffic lights indicating device that is arranged on each crossing according to the self-regulating traffic light systems of vehicle flowrate; Especially, each stop-light device also corresponding a flow detector of harnessing an animal to a cart; Described vehicle Flow Detection device is communicated with described governor circuit.
The vehicle Flow Detection device can detect the traffic state of corresponding road, promptly reacts the speed of this road wagon flow and the length of wagon flow.When all being transferred to governor circuit, the traffic state of each road carries out data analysis and processing, then governor circuit can calculate the stop-light controlling schemes that makes the road efficiency optimizationization by its default data model, thereby realizes improving the purpose of road service efficiency, intelligent control traffic.
Above-described vehicle Flow Detection device is one group of photoelectric sensor of arranging along the road driving direction preferably; Photoelectric sensor is communicated with governor circuit respectively.Survey by such one group of photoelectric sensor, can draw the density and the length of vehicle on this road.
In addition, can also carry out following improvement: corresponding each stop-light device is provided with a cover countdown display device, and the countdown display device is communicated with governor circuit respectively.Can provide waiting time indication intuitively to drivers like this.
The utility model has also added vehicle Flow Detection function and intelligent management function on the basis of original traffic light systems, make to alleviate the current pressure in crossing, to improve traffic efficiency in amplitude peak ground.And total system such as also has efficiently, stablizes at advantage.

Embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 1 and Figure 2, present embodiment is the traffic light systems of crossroad.By governor circuit, be arranged on the first traffic lights indicating device 2a at crossing, the second traffic lights indicating device 2b, the 3rd traffic lights indicating device 2c, the 4th traffic lights indicating device 2d, the first vehicle Flow Detection device 3a of corresponding successively above-mentioned stop-light device, the second vehicle Flow Detection device 3b, the 3rd vehicle Flow Detection device 3c and the 4th vehicle Flow Detection device 3d constitute, and also comprise the first countdown display device 4a of corresponding successively above-mentioned stop-light device, the second countdown display device 4b, the 3rd countdown display device 4c and the 4th countdown display device 4d.
The first traffic lights indicating device 2a, the second traffic lights indicating device 2b, the 3rd traffic lights indicating device 2c, the 4th traffic lights indicating device 2d, the first vehicle Flow Detection device 3a, the second vehicle Flow Detection device 3b, the 3rd vehicle Flow Detection device 3c, the 4th vehicle Flow Detection device 3d formation, the first countdown display device 4a, the second countdown display device 4b, the 3rd countdown display device 4c and the 4th countdown display device 4d all are communicated with governor circuit.
As shown in Figure 2, in the present embodiment, the first vehicle Flow Detection device 3a is arranged along the road driving direction by three photoelectric sensors 1 and constitutes.Can draw the density and the length of vehicle on this road like this.The second vehicle Flow Detection device 3b, the 3rd vehicle Flow Detection device 3c adopt and the identical scheme of the first vehicle Flow Detection device 3a with the 4th vehicle Flow Detection device 3d.
Governor circuit is receiving the first vehicle Flow Detection device 3a, the second vehicle Flow Detection device 3b, after the traffic state data of the 3rd vehicle Flow Detection device 3c and the relevant corresponding road of the 4th vehicle Flow Detection device 3d, can calculate the stop-light controlling schemes that makes the road efficiency optimizationization by its default data model, and control the first traffic lights indicating device 2a, the second traffic lights indicating device 2b, the duty of the 3rd traffic lights indicating device 2c and the 4th traffic lights indicating device 2d, and the first countdown display device 4a, the second countdown display device 4b, the countdown numerical value of the 3rd countdown display device 4c and the 4th countdown display device 4d shows, makes crossing traffic pressure greatly slow down.
What this instructions was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under principle of work of the present utility model and thinking all are considered as protection domain of the present utility model.
