The invention discloses an intelligent control method of a traffic signal lamp. A plurality of proximity switches are arranged in each driving direction at an intersection at equal intervals, when a vehicle passes or stops, the proximity switches in the corresponding positions can be switched on, then the continuous switching-on time of the proximity switches in all the driving directions is recorded, and then the continuous switching-on time of each proximity switch is compared with a preset threshold value; if the continuous conduction time of the proximity switches in one driving directionis smaller than a preset threshold value, it is judged that the driving direction is smooth, and if the continuous conduction time of at least one proximity switch in one driving direction is larger than the preset threshold value, it is judged that traffic jam occurs in the driving direction; and finally, the change of the traffic signal lamp is controlled according to whether traffic jam existsin each driving direction, the signal lamp is preferentially controlled to turn green for the driving direction with traffic jam, and the corresponding signal lamp is controlled to turn red for the driving direction with smooth traffic.

    本发明公开了一种交通信号灯的智能控制方法。通过在路口处每个行车方向上等间距设置多个接近开关,当有车辆经过或停留时对应位置处的接近开关会导通,然后通过记录所有行车方向上的接近开关的持续导通时间,然后将每个接近开关的持续导通时间与预设阈值进行比对,若一个行车方向上的多个接近开关的持续导通时间均小于预设阈值,则判定该行车方向畅通,若一个行车方向上存在至少一个接近开关的持续导通时间大于预设阈值,则判定该行车方向出现交通拥堵,最后根据每个行车方向是否存在交通拥堵来控制交通信号灯变化,对于出现交通拥堵的行车方向则优先控制其信号灯变绿灯,而对于交通畅通的行车方向则控制其对应的信号灯变红灯。
