Description
Technical field
The present invention relates to a kind of anti-traffic light control system that blocks up, be mainly used in the control traffic lights based on ground induction coil.
Technical background
Whether what traffic lights or traffic lights were controlled rationally is a key factor that influences the road cross traffic capacity, existing controlling system of traffic light is set in place in the traffic lights switch board in traffic lights roadside, action by central control unit control traffic lights switch, realize the conversion successively of traffic lights, this control system is provided with pattern setting device and manual control switch's device, by controlled variable such as pattern setting device input control traffic lights conversion sequence and switching times, realize the direct control of people by manual control switch's device to traffic lights, do not having under the manually-operated situation, traffic lights will carry out signal according to the cycle that the program of setting installs and fixes and change, and the vehicle on the control all directions road crosses the crossing.The defective of this technology is when the opposite congestion in road, when making the vehicle that sails the crossing into continue to travel, and stops the vehicle ' of other directions exactly, and all directions vehicle sails into and stops in the crossing, " inserts dead whole crossing ".For avoiding the appearance of this situation, relevant department's regulation opposite congestion in road vehicle occurs possibly can't roll the situation at crossing away from the time, even the vehicle that does not also allow not sail the crossing under the bright state of green light sails the crossing into, but the actual certain difficulty that implemented of this regulation, because driver's the visual field is stopped by front vehicles, can't judge accurately whole road conditions, can not determine whether can roll the crossing away from after sailing the crossing into when low running speed occurring, if at this moment the driver travels, emit possibly because of causing crossing congestion to hinder road traffic and facing punishment, travel if stop, might cause unnecessary time waste and stop travelling of follow-up vehicle, equally also form obstruction road traffic.
Summary of the invention
For overcoming the defective of prior art, the invention provides a kind of anti-traffic light control system that blocks up based on ground induction coil, this control system can be according to the jam situation of all directions road, sailing the crossing at vehicle can cause under the situation of crossing congestion, automatically traffic signals are arranged to and are remained red signal, sail into so that forbid vehicle, avoid the crossing is inserted dead.
The present invention realizes that the above-mentioned purpose technical scheme is: a kind of anti-traffic light control system that blocks up based on ground induction coil, comprise central control unit and some ground induction coils, described each ground induction coil is embedded in the crossing and sails out of on the road of direction, its output signal circuit connects described CPU (central processing unit) by interface circuit, described CPU (central processing unit) receives the vehicle actuated signal of ground induction coil, analyze and calculate crossing and the vehicle and the vehicle running state that sail out of on the direction road, carry out crossing and the judgement of sailing out of direction congestion in road degree according to convoy spacing and Vehicle Speed, the corresponding lights state that sails direction into of control is that red light is bright under congestion status, disappears until congestion status.
Because the present invention can monitor and judge the crossing automatically and respectively sail out of the jam situation of direction, and the control lights state is that red light is bright under congestion status, the vehicle of forbidding corresponding travel direction sails the crossing into, solved the difficult problem that whether can cross the crossing by driver's subjective judgement thus, avoided because of under congestion status, dead phenomenon being inserted at whole crossing because of vehicle sails the crossing into, judging the risk that is faced on the congestion status for having reduced the driver, avoided accurately to judge the driver's of congestion status punishment to only being subjected to the objective condition restriction, make the reasonable more and hommization of corresponding traffic administration, also guaranteed the unimpeded of crossing.
