| 摘 要： | 介绍了采用低压电力线载波通信技术的城市路灯智能监控系统.由电力线信道环境的特殊性所导致电力线载波通信的可靠性低和通信距离短等不足的特点,结合路灯分布的结构,提出一种独特的中继策略.该中继策略可以根据信道质量的变化动态地建立、维护、优化电力线通信网络路由,保证通信网络的有效性.文中阐述了中继策略的实现过程.实验表明,该方法可自适应地选择合适的中继节点,实现电力载波信号在电力线上的传输更加可靠、有效.该系统投入运行后稳定可靠,具有良好的应用和推广价值.

| Abstract: | An intelligent monitoring system for city street single lamp control is presented,in which the low-voltage power line communication is adopted.A unique relay strategy is proposed according to the characteristic including the short communication distance and bad reliability of power line communication which caused by the particularity of power channel environment and style structure for street lamp distribution.This relay strategy can not only construct but also maintain and optimize PLC networks' dynamic ro... |
