摘　　要：以扩大低压电力线载波网络的通信范围,提高通信的可靠性为目的,在分析低压电力线载波通信网络的组网特点和拓扑模型的基础上,提出了一种基于通信信号'信噪比'的简单且具有较高可靠性的自动组网方法。给出了该组网方法的具体步骤并用实例进行了解释说明,对该组网方法进行了仿真分析。结果表明该组网方法耗时较少,能够有效减小节点之间的'通信距离'并能找到多条通信路径,从而提高了整个网络的可靠性和实时性。In order to enlarge the range and enhance the reliability of the low-voltage power line communication network,a new simple automatic routing algorithm based on SNR of communication signals with better reliability is proposed based on the analysis of the routing characters and the logic topology model in this paper.Firstly,the specific steps of this routing algorithm are given and explained with corresponding example.Simulation and analysis are given,and the results show that this automatic routing algorithm is less time-consuming and can effectively reduce ＂communication distance＂ between nodes and find multiple communication paths,thus improving overall network reliability and enhancing the real-time performance.
