摘要
现在人们生活水平提高,汽车成为人们主要交通工具,交通堵塞就成为各大城市每到上下班高峰期时一道风景线。老实的交通信号都是固定时间模式,远远不能满足当今的城市交通要求。现在智能能交通信号机不仅可以通过红绿黄交通灯的控制,维持城市交通;还可以接收路面各类信息全盘控制城市交通,缓解城市交通拥挤等难题。智能交通信号机是控制单元也是执行机构,它直接影响城市交通管理能力。智能交通信号机有个主要功能就是能够检测路口各类车辆,通过CAN反馈给远程监控端。远程监控端及时了解城市各路口交通情况以便缓解城市交通堵塞拥挤。本论文设计一种基于PIC18F45芯片智能检测各类车辆,以便掌握城市各路口车辆动态,给城市道路交通优化提供有效数据。
Nowadays, people＇s living standards are improving, and automobiles are becoming the main means of transportation. Traffic jams become a scenic spot in every big city during rush hour. Honest traffic signals are fixed time mode, far from meeting the requirements of urban traffic nowadays. Intelligent traffic signal can not only maintain urban traffic through traffic lights, but also receive all kinds of road information to control urban traffic and alleviate urban traffic congestion. Intelligent traffic signal controller is a control unit and an executing agency, which directly affects the capacity of urban traffic management. Intelligent traffic signal has a main function is to detect all kinds of vehicles at the intersection, through the CAN feedback to the remote monitoring terminal. The remote monitoring terminal can understand the traffic situation at every intersection in order to alleviate the congestion and congestion of urban traffic. This paper designs a kind of intelligent detection system based on PIC18 F45 chip, in order to grasp the dynamics of vehicles at urban intersections and provide effective data for urban road traffic optimization.
