The invention relates to an intelligent street lamp dimming control method and system, and belongs to the technical field of illumination control, and the control method comprises the steps: obtaining the current traffic flow of a road section where each street lamp is located; determining a corresponding preset traffic flow threshold according to the road section where each street lamp is located; whether the current traffic flow of the road section where each street lamp is located exceeds a corresponding preset traffic flow threshold value or not is judged, if yes, the road section is determined to be a congested road section, and the street lamp brightness of the congested road section is adjusted to a preset brightness peak value; and if not, calculating a traffic flow ratio according to the current traffic flow of the road section and a corresponding preset traffic flow threshold value, obtaining a to-be-adjusted brightness value according to the traffic flow ratio and a preset brightness peak value, and adjusting the street lamp brightness of the road section according to the to-be-adjusted brightness value. The situation that driving safety is reduced due to the fact that a good lighting effect is not provided when vehicles on part of road sections are congested can be reduced, or electric energy is wasted due to the fact that vehicles on part of road sections are rare but the brightness is high can be reduced, and adaptability is improved.

    本申请涉及一种智能路灯调光控制方法及系统,属于照明控制技术领域,控制方法包括:获取各个路灯所在路段的当前车流量;根据各个路灯所在路段确定对应的预设车流量阈值;分别判断各个路灯所在路段的当前车流量是否超过对应的预设车流量阈值,若是,则确定路段为拥堵路段,并将拥堵路段的路灯亮度调节至预设亮度峰值;若否,则根据路段的当前车流量与对应的预设车流量阈值计算车流量比值,根据车流量比值与预设亮度峰值得到待调节亮度值,根据待调节亮度值对路段的路灯亮度进行调节。本申请能够减少部分路段车辆拥堵时未提供良好的照明效果导致行车安全性降低,或部分路段车辆稀少但亮度较高导致电能浪费的情况发生,提高了适应性。
