基于DL/T645规约的电能表集抄无线传感器网络MAC协议设计

摘要

With the rapid development of smart grid, the needs of remote and real-time management for the energy meter terminal and meter reading data communication have become an important research topic. Several challenging problems such as the communication mechanism of the layers of protocol and matching DL/T645 statute need to be solved when wireless sensor networks is applied in the multi-function power meter data communications. An improved IEEE802.15.4 QoS-MAC protocol for various types of data transmission in DL/T645 statute is proposed to build a MAC layer model in wireless sensor networks with real-time and reliable quality of service.%　　随着智能电网的发展，电力行业对各种电能表终端的远程、实时管理，以及对抄表数据的通信需求成为一项重要的研究课题.将无线传感器网络用于多功能电能表数据通信，需解决各层协议的通信机制和与DL/T645规约匹配等问题.文中提出了一种改进型的基于IEEE802.15.4的QoS-MAC协议，并针对电力DL/T645规约的电能表各类数据传输的特点以及集中抄表无线传感器网络的数据通信需求，构造了一种具有实时性和可靠性服务质量的无线传感器网络MAC层模型.
