Abstract
A self-adaptive proportional control traffic guidance signal system comprises a wireless video sensor, a host machine of a road traffic sign controlling machine, an extension machine of the road traffic sign controlling machine, a signal wireless transmission subsystem and a signal lamp. The wireless video sensor collects video signals, the video signals are transmitted to the host machine of a traffic guidance signal controller in a wireless manner after being processed by a special computer, traffic guidance control signals are transmitted through a wireless output subsystem after being analyzed and processed by the special computer in the host machine of the signal lamp, the control signals are converted to execution signals by the extension machine of the signal controller, and the execution signals are transmitted to the signal lamp through a lead wire and then are output by the signal lamp; in addition, the wireless video sensor is connected with the host machine of the road traffic sign controlling machine, and the extension machine of the signal controller is connected with the wireless output subsystem. Proportionally, the self-adaptive proportional control traffic guidance signal system outputs the control signals in time according to the current vehicle flow, that is, the green light time is prolonged when the number of passing vehicles is big at the crossing, and the green light time is shortened when the number of passing vehicles is small, so that accuracy of timely proportional control can be ensured.
Description
Technical field
The utility model relates to road traffic commander field, is specifically related to a kind of self-adaptation proportional control traffic commanding signal system.
Background technology
At present, China mainly adopts fixed time sequence teleseme control point duty signal.Because vehicle flowrate is often to change, and the unreasonable artificial traffic congestion that causes of clearance time usually occurs.Though this year occurred " intelligence " road traffic command system, effect is not too desirable.Intelligent road traffic command system commonly used adopts ground induction coil as sensor, and the industrial computer deal with data is also exported control signal, has following defective:
1, difficulty is installed, must constructs on sloping road;
2, owing to practical industry control deal with data, necessary practical constant temperature rack;
3, on the windows platform, work, have the unified problem that crashes and be subject to computer virus infection, make the reliability decrease of system.
4, because coil is embedded under the road, rolled by car, often damage and the reparation difficulty, influence serviceable life.
Another kind of intelligent road traffic command system, adopt the multi-purpose computer video to pounce on the technology of catching, on the windows platform, work, owing to do not control from hardware bottom layer, though the multi-purpose computer arithmetic speed is very fast, owing to done useless work a large amount of and that control is irrelevant, actual treatment is also unhappy several times, and unification is crashed and is subjected to computer virus infection, and system reliability is very low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art exactly and a kind of self-adaptation proportional control traffic signal system is provided.
The utility model adopts the radio video sensor of development voluntarily as sensor, gathers the on-the-spot vehicular movement vision signal in crossing, by electronic circuit selected digital image scope, and by computing machine image is carried out in good time analysis and judgement, obtains vehicle and passes through signal.The multi-direction vehicle flow signal that has 4 radio video sensors to obtain, be transferred on the self-adaptation ratio control signal machine by wireless device, the machine language that utilization relates to voluntarily gathers, analyzes, handles signals of vehicles on special purpose computer, what determine the clearance time in proportion according to all directions vehicle then.Because let pass the time according to vehicle condition adjustment at that time, under the condition that does not change road structure, practical the utility model can improve road passage capability more than 30%, can add up simultaneously and pass through vehicle.Change measurement parameter and can also detect pedestrian and non-exciting car quantity.Owing to adopt based on the control technology of chip and the software engineering of independent development, can calculate and control procedure several finishing in delicate, solve video sensor and be subjected to problems such as shades such as light power, vehicle buildings influence easily, thereby solved the accuracy problems of video frequency vehicle detecting device, guaranteed the accuracy of in good time ratio empty packet.
The purpose of this utility model is achieved in that a kind of self-adaptation proportional control traffic commanding signal system is by radio video sensor, road traffic signal controller main frame, road traffic signal controller extension set, signal wireless transmission subsystem, signal lamp.Gather vision signal by radio video sensor, through being wirelessly transmitted to point duty teleseme main frame after the special purpose computer processing, transmit the point duty control signal by wireless output subsystem after the special purpose computer analyzing and processing of teleseme main frame, the teleseme extension set is converted into the execution signal with control signal, to carry out signal by lead and transfer to signal lamp output, radio video sensor is connected with the road traffic signal controller main frame, the teleseme extension set is connected with wireless output subsystem, the utility model is exported control signal in proportion according to vehicle flowrate at that time in good time, promptly the vehicle by the crossing prolongs the clearance time, and vehicle shortens the clearance time after a little while.

Embodiment
The utility model is shown in Fig. 1 .2.3, and it is made up of radio video sensor, road traffic signal controller main frame, road traffic signal controller extension set, signal wireless transmission subsystem, signal etc.Radio video sensor is installed in 6 meters high signal lamps or light pole gets final product, use the gimbal radio video sensor, opening power, gather vision signal by radio video sensor, through being wirelessly transmitted to point duty teleseme main frame after the special purpose computer processing, wireless output point duty control signal after special use in the teleseme main frame and the Sun Ji analyzing and processing, the teleseme classification is converted into the execution signal with control signal, will carry out signal by lead and transfer to signal lamp output.
