摘要
由于电力线信道环境的特殊性,致使电力线载波抄表系统中存在着的抄表距离有限、通信成功率不高等问题。从提高通信可靠性的角度出发,文章探讨了电力线载波中继路由技术,并结合蚁群优化算法原理,提出了一种新的动态路由方法。该方法按照节点间的电气距离,根据电力线信道状态动态地建立和维护载波中继路由,保证了通信的成功率。通过采用候选集策略能够提高中继搜索的准确度和效率。仿真发现,该方法能够准确地找到中继路由,为扩大电力线载波抄表范围提供了一种有效的路由方法。
Due to the particularity of power line communication channel, the automatic meter reading system （AMRS） based on power line carrier has some problems such as restricted meter reading distance and poor reliability of communication. This paper discusses the relay routing technology in PLC carrier aiming at improving the communication reliability. A new dynamic routing method based on ant colony algorithms is been designed. This method can dynamically set up and maintain the relay routing in PLC carrier based on electric distances among nodes and PLC channel, so the reliability of communication is been improved. The use of candi- dates set can improve the accuracy and efficiency of searching routing. Simulation indicates that the method can find the relay routing accurately and is an effective way for large scale automatic meter reading.
