Description
Technical field the utility model relates to a kind of intelligent traffic light device that is used for highway system T shape crossing, especially relates to a kind of intelligent traffic light device of T shape crossing of double speed symmetric form highway system.
Background technology in the prior art, the traffic lights of crossroad are fixed switching time, when wagon flow on and off duty peak, the wagon flow at four crossings overlaps, and is easy to cause traffic congestion by traffic lights commanders; The crossroad was too much during present highway was arranged, had a strong impact on the vehicle flowrate in city, built viaduct in a large number for making smooth traffic, the big and inconvenient walking of investment; In addition, existing T shape crossing traffic lights are provided with unreasonable, and what have does not have traffic lights, and traffic hazard and traffic congestion happen occasionally, thereby need to improve.
The summary of the invention the purpose of this utility model is to provide a kind of intelligent traffic light device that is used for highway system T shape crossing, and this intelligent traffic light device is used for the T shape crossing that is connected with the double speed highway, reaches the purpose of vehicle Fast transforms track and safety traffic.
In order to achieve the above object, the utility model provides following technical scheme: design a kind of intelligent traffic light device that is used for highway system T shape crossing, be positioned at the left side at T shape crossing, in, by right three crossings, has the control casing, display lamp and control circuit, each traffic lights device is equipped with the signal inductor of sending a car (5) at three crossings respectively, the signal inductor (5) of respectively sending a car links to each other with identification priority circuit (6) respectively, identification priority circuit (6) directly links to each other with intelligence control circuit (7), intelligence control circuit (7) and respectively with respectively in advance display lamp (4) link to each other with each traffic lights (1), intelligence control circuit (7) links to each other with each disconnected wagon flow inductor (2) respectively.Described intelligence control circuit (7) can adopt the GDH-T type.The signal inductor (5) of sending a car is delivered to identification priority circuit (6) with monitored signal, and give intelligence control circuit (7) signal branch precedence, intelligence control circuit (7) is by the signal successively green light or the red light of bright left, center, right of sending a car, intelligence control circuit (7) is provided with the time that fixedly gives a green light, when disconnected wagon flow inductor (2) when not having output signal, give a green light in the setting-up time, setting-up time is to just changing traffic lights always.If what give a green light a road does not send a car and exceeded the time of setting, disconnected wagon flow inductor (2) output signal is also delivered to intelligence control circuit (7) with signal, by the conversion of intelligence control circuit (7) control traffic lights (1).Can be away from the display lamp (4) in advance at crossing early with the mode driver that sends out a warning before the crossing sends out a warning, slow down and car is parked in the stop line inboard.
The utility model technical scheme preferably is: in advance display lamp (4) be positioned at direction to the car away from by the crossing, the signal inductor of sending a car (5) is positioned at that display lamp (4) is other in advance.Can in time show in advance, make the driver know that in advance the front is red light or green light, accomplishing to know what's what and can slowing down then is parked in car in the stop line, or passes through by normal speed of a motor vehicle safety.
The utility model technical scheme preferably can be: disconnected wagon flow inductor (2) is positioned at by the road surface stop line of place highway.When having crossed, car can in time send a signal to intelligence control circuit (7), by the conversion of intelligence control circuit (7) control traffic lights (1).
Compared with prior art, the utlity model has advantages such as simple in structure, esy to use, safe and reliable, can in time show in advance and send a car, make the driver know that the traffic lights at crossing, front show situation, minimizing is brought to a halt.According to the circuit setting, when sending a car, each crossing all do not give a green light, send a car when having only a crossing, this crossing gives a green light intact excessively until car always, other crossings will have been crossed just at car and give a green light, and take turns stream translation in order, and that does not send a car a road does not give a green light, what car was intact excessively a road changes another road immediately, has avoided the generation of traffic hazard and traffic congestion effectively.
Be description of drawings of the present utility model below the description of drawings:
Fig. 1 is that the integrated highway system of double speed symmetric form is arranged synoptic diagram;
Fig. 2 is the position view of the utility model at T shape crossing;
Fig. 3 is a schematic block circuit diagram of the present utility model.
Among Fig. 1, T1～T14 is the T shape crossing in city, and P1～P16 is parking lot, incity, city (PARK);
Among Fig. 2, the 1st, traffic lights (comprise a left side 1, right 1 and in 1 three), the 2nd, disconnected wagon flow inductor (comprise a left side 2, right 2 and in 2), the 3rd, stop line (comprise a left side 3, right 3 and in 3), the 4th, in advance display lamp (comprise a left side 4, right 4 and in 4), the 5th, the signal inductor of sending a car (comprise a left side 5, right 5 and in 5), the 8th, highway, the 9th, circulation track, the 10th, low speed road.
Among Fig. 3, the 1st, traffic lights, the 2nd, disconnected wagon flow inductor, the 3rd, stop line, the 4th, shift to an earlier date display lamp, the 5th, the signal inductor of sending a car, the 6th, identification priority circuit, the 7th, intelligence control circuit.
By specific embodiment the utility model is carried out more detailed description below the embodiment:
With reference to Fig. 3, be used for highway system T shape crossing the intelligent traffic light device have a signal inductor of sending a car (5), the signal inductor (5) of respectively sending a car links to each other with identification priority circuit (6) respectively, identification priority circuit (6) directly links to each other with intelligence control circuit (7), intelligence control circuit (7) and respectively with respectively in advance display lamp (4) link to each other with each traffic lights (1), intelligence control circuit (7) links to each other with each disconnected wagon flow inductor (2) respectively.
