Abstract
The utility models discloses an intelligent traffic light, which comprises traffic lights, a traffic light controller, a plurality of infrared monitors positioned at every other crossing, wherein the output end of the infrared monitor is electrically connected with the input end of a sampling circuit; the output end of the sampling circuit is connected with the input interface of a microprocessor; the output interface of the microprocessor is connected with the signal port of the traffic light controller. The utility model has the advantages that the information obtained by the infrared monitors positioned at every other crossing is transmitted to the processing chip to judge whether the traffic is in a static state (a motionless state of vehicles in a traffic jam) or in a dynamic state (the vehicles are moving), then the judgment is transmitted to the controller to make a due treatment.
Description
Technical field
The utility model relates to traffic lights, especially relates to intelligent traffic lights.
Background technology
The modern city traffic scrambling of vehicle flowrate, direction usually occurs owing to region, the difference of time.Be that the commuter time vehicle flowrate is big and the working time vehicle is less relatively, it is stronger to show as the wagon flow directivity simultaneously.And each crossing of traditional traffic lights is logical, the forbidden time is the artificial fixed value of setting, therefore can not adjust logical, the forbidden time at each crossing constantly automatically according to the vehicle flowrate size, do not reach and utilize limited road traffic resource rationally and effectively, cause the waste of resource.
The utility model content
The utility model purpose is to provide a kind of can adjust automatically that each crossing is logical, the intelligent traffic lights of forbidden time.
For achieving the above object, the utility model can be taked following technical proposals:
Intelligent traffic lights described in the utility model, it comprises signal lamp and traffic controller, it is characterized in that: the output terminal that is disposed on a plurality of infrared monitor control devices at each crossing is electrically connected with the sample circuit input end; Described sample circuit output terminal is connected with the microprocessor input interface; Described microprocessor output interface is connected with described traffic controller signal port.
Advantage of the present utility model is to pass to process chip by being disposed on the information that the infrared monitor control device measures, chip judges it is that (static state is meant out-of-work vehicle to static state thus, phenomenon just blocks up) still dynamic (dynamically being meant the vehicle that is moving), after the analyzing and processing, pass to controller in the information gained, controller is made corresponding processing.If the infrared monitor control device all is in dynamically or all is in static state, controller can be by original program run.Judge that by 5 infrared monitor control devices at each crossing which crossing seriously blocks up, which crossing slightly blocks up, and which crossing is normally moved, and is dealt with by controller then.If the 1st, 2 the infrared monitor control device on thing road is static, gone bad a car before the 5th the infrared monitor control device, also be static, process chip is several being as the criterion in the past, and just this crossing only blocks up 20 meters, then information is passed to controller and makes respective handling.If 5 infrared monitor control devices on thing road all are static, preceding 2 of the north and south road is static, and the thing road can transfer green light automatically to.
