Description
Technical field
This utility model belongs to means of transportation technical field, relates to traffic signal system, especially a kind of intelligent traffic signal system.
Background technology
Along with development and the raising of living standards of the people in city, motor vehicles is possessed quantity and is continuously increased.Whole nation vehicle guaranteeding organic quantity reaches 2.64 hundred million, wherein 1.54 hundred million, automobile；Vehicle driver breaks through 300,000,000 people, and wherein motorist is more than 2.46 hundred million people." block up " common fault becoming most cities, also become people and go out the problem of headache.Crowded city cannot meet people by widening road and go on a journey needs.The problems such as urban track traffic is again because of costly, long in time limit, technical merit bottleneck are endured to the fullest extent and are denounced.The increase of automobile quantity is reduced by modes such as the limit board numbers of shaking in current domestic several megalopolis, and result is the most not fully up to expectations.In allegro big city of living, improve traffic jam issue, can indirectly promote the lifting of economic benefit.The motor vehicles Sources controlling that just need to make of the quick vehicles is produced little effect by citizen, it is desirable to urban transportation facility can be increased operation rate to greatest extent, solves interurban communication congestion problems, improves traffic.
Application number 201120478847.2 utility model patent, a kind of intelligent traffic light control system based on vehicle flowrate is disclosed, including probe, controller, LED display screen, central processing unit, probe is infrared visible CCTV camera, controller is connected with LED display screen and traffic light system, central processing unit is connected with probe and controller, it is achieved according to vehicle flowrate intelligent decision traffic lights duration, improves crossroad and passes through efficiency.
Patented product disclosed above passes through CCTV camera Real-time Collection crossing information of vehicles, carries out crossing traffic display lamp regulation in this, as basis for estimation.In use can there is subproblem in this intelligent traffic light control system based on vehicle flowrate, on the one hand when in the face of the relatively low haze of visibility or rainy weather, the imaging system of video camera can be impacted, accuracy；Additionally the maintenance of video camera is relative complex, and using to means of transportation makes troubles.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of intelligent traffic signal system, urban road intersection access road arranges wagon detector, traffic light timing scheme has been calculated by intelligent signal controlling machine, the car flow information that can detect with detector and change at any time, can improve traffic situation, more intuitively, intelligence, solve congestion problems flexibly.
The technical solution of the utility model is as follows:
A kind of intelligent traffic signal system, is made up of ground induction coil, signal control chamber and signal lights.Ground induction coil is positioned under car lane road surface, and signal control chamber is positioned at every turnpike road side roadbed, and signal lights is erected at the top at car lane crossing by lamp stand.
Ground induction coil is an oscillator coil, it is embedded in below car lane road surface, this coil is a part for oscillating circuit, ground induction coil and electric capacity composition oscillating circuit can produce oscillator signal, oscillator signal is sent to the frequency measurement circuit being made up of single-chip microcomputer by changer, and function of the MCU module can measure the frequency of this agitator.When there being big metal object (such as automobile) through out-of-date near ground induction coil, owing to space medium changes thus causing the change of oscillating circuit frequency of oscillation, when metal object is near ground induction coil, frequency of oscillation raises.Therefore, it can according to the change of frequency of oscillation that ground induction coil produces judge now at oscillator coil whether with the presence of motor vehicles.
Signal control chamber connects ground induction coil and signal lights, is the control axis of intelligent traffic signal system, has measurement module, data analysis module and coordinating control module in signal control chamber.Measurement module includes multiple frequency measurement circuit being connected with ground induction coil, and main being responsible for receives the oscillator signal that in major trunk roads, below every car lane, ground induction coil produces；Oscillating circuit information in every car lane in the major trunk roads of measurement module collection is analyzed by data analysis module, thus judge that major trunk roads crossing moves ahead, turns left, waits in right-turn lane the quantity of vehicle, and every car lane waiting, the quantity of vehicle is started to coordinating control module；Coordinating control module is mainly responsible for sharing of information between multiple signal control chamber, four, crossroad major trunk roads are distributed signal control chamber everywhere, coordinate control by respective Coordination module each other, and represent coordinating result in the way of respective traffic signal timing duration.If the wait vehicle fleet size that signal control chamber detects a specific direction is the biggest, the traffic signal timing duration of all directions at crossroad can be adjusted accordingly, suitably increase the transit time of direction road, to reduce crossing average waiting duration, reach to optimize the purpose of traffic signalization.
Signal lights is erected at above car lane by lamp stand, and as the executor of traffic signal, the signal sent after accepting to be coordinated to control by signal control chamber controls information.Ground induction coil below crossing inlet car lane is as wagon detector, traffic light timing scheme is calculated by signal control chamber, traffic signal timing can be changed at any time, it is achieved the Based Intelligent Control of traffic signal at urban road intersection with the car flow information that detector detects.
Ground induction coil is distributed with same intervals in every car lane, arranges first ground induction coil, arrange a ground induction coil at interval of 20m afterwards, lay ground induction coil at three in typically every car lane at distance stop line 19.8m.
As preferably, can signal control chamber be integrated in inside Traffic signal post, convenient management, it is to avoid extraneous destruction.
The invention have the advantages that this intelligent traffic signal system, wagon detector is arranged on below car lane, and the information of vehicles in measurement road is accurately and reliably；With actual tailback information as foundation, carry out Intersections timing and dynamically adjust, reduce urban road intersection and averagely block up the time, improve traffic efficiency.
