面向复杂路段的可控智能交通信号灯设计 -视频分享

二、项目简介

题目：面向复杂路段的可控智能交通信号灯设计
主控:STM32
显示:OLED显示屏
红外光电*2
DHT11温湿度传感器
光检测模块：光照传感器
声音传感器
雨滴传感器
4g模块
功能：
1、实时检测当前温湿度，光照强度，雨滴情况，车流量
2、可通过按键切换页面
3、数据可通过4g模块发送到云端。
4、默认白天（红10s，绿10s，黄3s），晚上（红15s，绿15s，黄3s），当有雨出现时（红17s，绿17s，黄3s）
5、当声音检测超过70时，自动判定为紧急车辆通行，全部红灯10s，结束后，才会恢复。
6、可按键控制灯的时长，灯时长变化情况还按原基础的情况加以变化。
7、光电检测车流量，流量过大（超过10后），如果白天则按（红15s，绿15s，黄3s），如果晚上则不变（红15s，绿15s，黄3s）。
