课题名称 基于电力载波的交通灯监测系统设计 摘 要 电力载波是电力系统特有的通信方式，电力载波通讯是指利用现有电力线，通过载波方式将模拟或数字信号进行高速传输的技术。最大特点是不需要重新架设网络，只要有电线，就能进行数据传递。Abstract Power Line Carrier is a unique power system communication, power line carrier communications is the use of existing power line, through the carrier means to carry out high-speed analog or digital signal transmission technology. Feature does not require re-erected the largest network, as long as electric wires, data can pass. With the development of science and technology, power line carrier technology in the work life of application technology has got great development. Power line carrier technology is not only use in application of micro-computer, but also quickly entered the digital age. Growth and development needs of Power Line Carrier in many areas including intelligent appliances, remote meter reading, remote control and other aspects have been greatly improved. In recent years, power line carrier technology in medium / low-voltage power communication technology development and Applications presents the prosperous situation .This paper designs a traffic light monitoring system based on Power Line Carrier .With the development of a modern economy, traffic lights is playing an increasing role in road traffic control .The need to implement the functionality of the system is Using power line carrier communications, design real-time feedback of the traffic lights . Monitoring module to read the traffic lights work state, the state feedback to the computer, read by staff, thus realize the traffic signal lamp remote monitoring .The system is designed to be simple, easy to operate, the system show us high reliability, good performance in the application of it, and it can ensure road safety, extend the lamp life and reduce operation and maintenance costs. Key words: Power line carrier、Remote monitoring、 traffic lights 目录 目录 3 1 绪论 4 1.1 课题背景及现实意义 4 1.2 国内外研究现状 4 1.3 电力载波通信的优势与存在缺点 5 1.4本文的主要内容 6 2 系统方案设计 7 2.1系统框架及工作原理 7 2.2 系统
