摘　　要：设计了一种以C8051F系列微处理器与ST7538Q载波芯片为核心元件的电力线载波Modem。为了提高自动抄表系统的可靠性,探讨了基于人工蛛网与Dijkstra算法相结合的路由组网策略。针对系统存在故障节点的情况,以双层蛛网为例作了仿真分析,仿真结果表明:采用Dijkstra算法比遗传算法的求解速度快,搜索到最优路径的成功率也较高。A power line carrier Modem which takes C8051F microcontroller and ST7538Q as core components was designed. In order to improve the reliability of meter auto-reading system,a routing network algorithm which based on combining artificial cobweb algorithm with Dijkstra algorithm was discussed; and aiming at fault nodes in the system,the double-layer cobweb algorithm was taken as an example. Simulation results show that the Dijkstra algorithm outperforms the genetic algorithm in solving problems and obtaining optimal solutions.
