Abstract
The utility model provides a kind of fuzzy control system of traffic signal lamp.Comprise video collector, A/D converter, fuzzy controller, first data transmission module, aobvious time device, signal lamp, server and the second data transmission module.Video collector is by A/D converter connection mode fuzzy controllers, fuzzy controller connects first data transmission module, aobvious time device and signal lamp, server connects the second data transmission module, and fuzzy controller is by first data transmission module and the second data transmission module connection server.The utility model system architecture is simple, strong to urban traffic signal cooperation control ability, can effectively reduce Single Intersection average vehicle delay, strengthens the traffic capacity of crossing, reduces the hold-up time of motor vehicles on street.
Description
Technical field
The utility model belongs to field of traffic control, is specifically related to a kind of fuzzy control system of traffic signal lamp.
Background technology
Traffic is the lifeblood of urban economy activity, plays a very important role the raising of urban economy development, living standards of the people.In recent years, along with the continuous growth of economy, the development rapidly of urbanization, motorize, urban road increase limited increase with vehicle infinitely cause serious congested in traffic problem, wherein serious with the traffic jam issue of crossing.Follow and show according to data, the economic loss caused because of traffic jam is every year up to tens dollars, now become the bottleneck of restriction economic development and urban construction, this is also to traffic signal control system and needs each intersection comprehensive of each intersection simultaneously, and the system of carrying out whole urban traffic signal control is had higher requirement.
Traffic system is one and has randomness, ambiguity and probabilistic complication system.The static timing controlled of traditional traffic lights, for traffic intersection signal lamp distributes regular time, it is a kind of opened loop control, do not consider the fluctuation of Real-Time Traffic Volume, its control ability and antijamming capability are very limited, even occur the abnormal phenomenon that time that the direction that flow is large is distributed on the contrary is few so classical control methods is difficult to obtain satisfied effect.Fuzzy control be a kind of need not the control method of mathematical model, it can imitate thinking when experienced traffic police directs traffic, and reaches good control effects.
Utility model content
One of the utility model object is to overcome above the deficiencies in the prior art, provides a kind of fuzzy control system of traffic signal lamp.
A kind of fuzzy control system of traffic signal lamp that the utility model provides, comprise video collector, A/D converter, fuzzy controller, first data transmission module, aobvious time device, signal lamp, server and the second data transmission module.
Video collector is by A/D converter connection mode fuzzy controllers, fuzzy controller connects first data transmission module, aobvious time device and signal lamp, server connects the second data transmission module, and fuzzy controller is by first data transmission module and the second data transmission module connection server.
Further, described fuzzy controller adopts PLC control panel.
Further, described video collector is arranged on signal lamp upper end, and before and after each signal lamp upper end, two sides respectively arranges one, and each crossing arranges 8 video collector altogether.
The beneficial effects of the utility model are, the utility model system architecture is simple, strong to urban traffic signal cooperation control ability, can effectively reduce Single Intersection average vehicle delay, strengthen the traffic capacity of crossing, reduce the hold-up time of motor vehicles on street.
Accompanying drawing explanation
Figure 1 shows that the utility model fuzzy control system of traffic signal lamp structural representation.
Embodiment
Hereafter will describe the utility model in detail in conjunction with specific embodiments.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.
As shown in Figure 1, a kind of fuzzy control system of traffic signal lamp that the utility model provides, comprise video collector 1, A/D converter 2, fuzzy controller 3, first data transmission module 4, aobvious time device 5, signal lamp 6, server 7 and the second data transmission module 8.
Video collector 1 is by A/D converter 2 connection mode fuzzy controllers 3, fuzzy controller 3 connects first data transmission module 4, aobvious time device 5 and signal lamp 6, server 7 connects the second data transmission module 8, and fuzzy controller 3 is by first data transmission module 4 and the second data transmission module 8 connection server 7.
Further, described fuzzy controller 3 adopts PLC control panel.Structure is simple, and easy to use, versatility is good, and cost performance is high.
Further, described video collector 1 is arranged on signal lamp upper end, and before and after each signal lamp upper end, two sides respectively arranges one, and each crossing arranges 8 video collector 1 altogether.
Embodiment:
Whole system is placed on crossing, each arterial highway, crossing.First, video collector 1 is utilized to gather the traffic flow data in each track; Then, after being nursed one's health by A/D converter 2, the traffic flow data in each track collected is sent in fuzzy controller; Subsequently, after fuzzy controller 3 carries out analyzing and processing, select this phase place given a green light next, and release the green time of this phase place given a green light next simultaneously; Finally, device 5 and signal lamp 6 when this phase place given a green light of the next one released by fuzzy controller 3 and its green time information that should continue are used for aobvious, thus the traffic of crossing is controlled in real time; Wherein, fuzzy controller 3 can also carry out radio communication by first data transmission module 4 and the second data transmission module 8 with the server 7 of supervisory control desk.
The utility model system architecture is simple, strong to urban traffic signal cooperation control ability, can effectively reduce Single Intersection average vehicle delay, strengthens the traffic capacity of crossing, reduces the hold-up time of motor vehicles on street.
Although given embodiments more of the present utility model, it will be understood by those of skill in the art that when not departing from the utility model spirit herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of the utility model interest field.
