摘　　要：针对入户配电网结构复杂、干扰严重、抄表系统内部各点之间不能完全实现直接通信的特点,采用动态路由中继方法,提出基于可预测p-保持载波侦听多路访问(CSMA)机制,根据预测信道上的数据流量来确定发送时隙。阐述了蚁群路由算法和洪泛路由算法应用于电力载波抄表网络的具体方案,设计和开发出一种适合于电力载波抄表系统的组网方式。基于NS2网络仿真软件对AdHoc网络中的按需距离矢量路由(AODV)协议进行了仿真测试,结果表明采用该自动路由技术可以提高低压电力载波抄表快速性和可靠性。Due to strong time-varying interference caused by the complex structure of dwelling-entering distribution network, the direct communication among internal points of meter-reading system cannot be completely implemented. For this reason, by use of dynamic routing relaying and on the basis of predictive p-persistent carrier sense multiple access （CSMA） mechanism, the sending time-slot can be determined by predicting the data flow in channels. The concrete scheme of applying ant colony routing algorithm and flood routing algorithm to meter-reading network through power line carrier is expounded, and a networking mode that suits to meter-reading network through power line carrier is developed. The simulative testing of Ad hoc on-demand distance vector （AODV） routing protocol is carried out based by NS2 simulation software, test results show that by use of the proposed auto-routing technology the reliability and rapidity of meter-reading through low voltage power line carrier.
