The invention discloses an intelligent traffic signal lamp. The intelligent traffic signal lamp comprises a signal machine, a plurality of color lamp group loops used for displaying different color signals and a countdown lamp group loop. Each color lamp set loop comprises a first ACDC module, a color lamp set and a first detection module, the first AC/DC module is connected with the signal machine and the color lamp set and used for supplying power to the color lamp set so that the color lamp set can be turned on or turned off, and the first detection module is used for detecting the turning-on state of the color lamp set; the countdown lamp group loop comprises a second AC/DC module, a processor module and at least one countdown lamp group, the second AC/DC module is used for supplying power to the processor module based on the alternating current output by the signal machine, and the processor module is used for controlling the countdown lamp group to execute countdown display according to the lightening state of the color lamp group. According to the scheme, the display of the countdown lamp group also refers to the actual lightening state of the color lamp group, so that wrong display caused by induced voltage on a power-free loop is avoided.

    本申请公开了一种智能交通信号灯,包括信号机、多个用于显示不同颜色信号的颜色灯组回路和一个倒计时灯组回路。每个颜色灯组回路包括一个第一AC\DC模块、一个颜色灯组和一个第一检测模块,第一AC/DC模块分别与信号机、颜色灯组连接,用于对颜色灯组供电,以使颜色灯组点亮或关闭,第一检测模块用于检测颜色灯组的点亮状态;倒计时灯组回路包括一个第二AC/DC模块、处理器模块和至少一个倒计时灯组,第二AC/DC模块用于基于信号机输出的交流电对处理器模块实施供电,处理器模块用于根据颜色灯组的点亮状态控制倒计时灯组执行倒计时显示。从方案可以看出,倒计时灯组的显示还参考了颜色灯组的实际点亮状态,因此不会因无电回路上的感应电压导致错误显示。
