Embodiment

Below in conjunction with specific embodiments content of the present utility model is described.

As shown in Figure 1 to Figure 3, be a kind of cooperative type traffic signal controller structural representation described in the utility model.A kind of cooperative type traffic signal controller described in the utility model, comprise: the traffic lights 1 being arranged at crossroad place, described traffic lights 1 comprise second pulse generator 11, down counter 12 and state controller 13, described second pulse generator 11 connects and controls described down counter 12, and described down counter 12 connects and controls described state controller 13; For the shortcut mouth vehicle checker 2 of the vehicle of 5 ~ 10 meters of distant places, monitoring distance crossroad, with the long way mouth vehicle checker 3 of the vehicle for 30 ~ 100 meters of distant places, monitoring distance crossroad, described shortcut mouth vehicle checker 2 is provided with acceleration pulse generator 21, described acceleration pulse generator 21 is for sending pulse signal to described down counter 12, described long way mouth vehicle checker 3 is provided with relay 31, and described relay 31 is for controlling the break-make of described second pulse generator 11 and described down counter 12.Specifically optimally, described shortcut mouth vehicle checker 2 and described long way mouth vehicle checker 3 are inductor wire ring type vehicle checker, and described shortcut mouth vehicle checker 2 and described long way mouth vehicle checker 3 include at least two telefaults 4, the spacing between the telefault 4 of described shortcut mouth vehicle checker 2 or described long way mouth vehicle checker 3 is 0.5 ~ 3 meter.Described second pulse generator 11, described down counter 12 and described state controller 13 is the electric appliance component that existing traffic signal indicating lamp is conventional, at this without the need to repeating its structure and principle of work; Described acceleration pulse generator 21 directly can adopt continuously adjustable 555 pulse producers of commercially available dutycycle.

As everyone knows, its major function of the traffic signal indicating lamp of crossroad is realized by second pulse generator 11, down counter 12 and state controller 13, down counter 12 has the recurrent state value of fixed qty, the signal that down counter 12 sends according to second pulse generator 11 variable condition value send signal to state controller 13 successively, state controller 13 controls the traffic lights indicating status in two road according to the state value of down counter.In the current peak period of easy congested link, the road green light in this direction triggers described shortcut mouth vehicle checker 2 when lighting and described long way mouth vehicle checker 3 carries out work, when long way mouth vehicle checker 3 monitors vehicle, illustrate that on this road, tailback is more, long way mouth vehicle checker 3 makes relay 31 disconnect connection between described second pulse generator 11 and described down counter 12, described down counter 12 state stops, namely existing green light phase is kept, and countdown stops, unlimited time delay, until vehicle is reduced to long way mouth vehicle checker 3 when monitoring less than vehicle on this road, connection between described second pulse generator 11 and described down counter 12 recovers, continue countdown, when on vehicle passes through comparatively smooth and easy or this road between shortcut mouth vehicle checker 2 and long way mouth vehicle checker 3, vehicle is less, shortcut mouth vehicle checker 2 can't detect vehicle, then Acceleration of starting pulse producer 21, make described down counter 12 accelerate work, thus state of a control controller 13 switch the indicating status of traffic lights as early as possible.Inductor wire ring type vehicle checker is conventional lower-cost vehicle checker, but its shortcoming is that the width detected generally only has two meters, when being greater than two meters to prevent vehicle clearance, described shortcut mouth vehicle checker 2 and described long way mouth vehicle checker 3 are monitored less than vehicle, the utility model devises the vehicle checker of two telefaults or many telefaults, and shortcut mouth vehicle checker 2 and long way mouth vehicle checker 3 can be avoided to monitor the situation of the vehicle less than excesssive gap.
