摘　　要：在电力线与无线融合通信系统中,为了保证通信质量,需要根据环境的变化对2种信道进行切换,在干扰复杂的环境下能够有相适应的信道来完成高质量通信。文章基于层次分析方法,按照电力线与无线信道带宽、信道容量、吞吐量、出错率等4项因素,建立系统阶梯层次结构模型,确定电网通信站点的通信机制,通过无线通信收发机或电力线通信收发机发送切换指令,实现电力线与无线信道切换。最后,设计基于该算法的远程抄表系统。In the power line and wireless convergence communication system, to ensure the quality of communication, switching between two types of channels according to the changes in the environment is needed to achieve a suitable channel to complete high-quality communications under complex interference environment. Based on analytic hierarchy process and considering four issues including power line and wireless channel bandwidth, channel capacity, throughput and error rate, this paper established a system ladder hierarchy model, determined the communication mechanism for the power grid communication station, which transmits and receives the data switching instructions through the wireless or the power line communication transceiver to achieve power lines and wireless channel switching. Finally, the remote meter reading system based on the proposed algorithm is designed.
