LED 路灯监控系统是应用了电力线载波通信( PLC:power line communication) 技术以后，基于蚁群算法(ACA:ant colony algorithm)研发出的一种可应用在低压配电网的LED 路灯组网寻址算法，同时围绕目标函数、信息素更新规则与状态转移规则和搜索等要素进行了修正与完善，不仅构建了路灯自动路由模型，还拟定出自动路由协议框架. 凭借该模型，低压配电网信道质量可以实现动态识别，同时通过信道质量变化，电力线载波通信网络路由也能够完成动态维护，从而进一步实现通信网络的可靠性. 最后，这种方法的实践性及可靠性在信道仿真模型及现场试验的协助下得以验证.

LED streetlamp monitoring system is an application of PLC( power line communication) technology. 　A LED street network addressing algorithmis developed，which can be used in low voltage distribution network based on ACA( ant colony algorithm). Wepay focus on the objective function，the pheromone updating rule and state transition rule and search and other elements of the revision and improvement，it constructs not only the automatic routing model，but also a framework of automatic routing protocol. With this model，the low - voltage distribution network channel quality can be identified dynamically. Through the change of channel quality，routing power linecommunication network can complete the dynamic maintenance，so as to further realize the reliability of communication network. Finally，the practice and reliability of this method are verified by the simulation model of the channel and the assistance of the field test.
