6LoWPAN协议在电力物联系统中的应用研究

Research on the application of 6LoWPAN protocol in power IOT system

摘要:

当前电力物联网系统应用Zigbee协议,该协议不能满足IEE802.15.4的MAC层的Ipv6需求,造成电流传输速率低,且电压越限开关控制失败。为此,采用6LoWPAN协议优化了电力物联系统的网关功能。利用6LoWPAN技术原理、应用规范以及相比于其它物联网的优势,基于IEE802.15.4的网络层协议,提出Zigbee和6LoWPAN共存,协议中间层为双协议栈网关的总体设计方案,实现物联网与Ipv6 Internet的互联和信息交互。设计6LoWPAN适配层,解决IEE802.15.4的MAC层不能满足Ipv6需求问题。仿真结果显示：应用6LoWPAN协议后电力物联系统连通性能以及UDP数据报传输性能均符合实际应用需求；6LoWPAN协议应用后可显著提升数据采集节点的续航时间,降低功耗,增加电流传输速率,提升电压越限开关控制成功率。6LoWPAN协议的应用可有效提升电网的安全运行水平。

Abstract:

The current power IoT system uses the Zigbee protocol. This agreement cannot meet the IPV6 requirements of the MAC layer of IEE802.15.4, resulting in a low current transmission rate and failure of the voltage over-limit switch control. To this end, the 6LoWPAN protocol is used to optimize the gateway function of the power IoT system. Based on the 6LoWPAN technology principle, application specifications, and advantages compared to other Internet of Things, based on the network layer protocol of IEE802.15.4, Zigbee and 6LoWPAN coexist, and the protocol middle layer is the overall design of the dual protocol stack gateway to realize the Internet of Things and IPv6 Internet interconnection and information exchange. The 6LoWPAN adaptation layer is designed to solve the problem that the MAC layer of IEE802.15.4 cannot meet the requirements of IPv6. The simulation results show that the connectivity performance of the power IoT system and the UDP datagram transmission performance after applying the 6LoWPAN protocol meet the actual application requirements; the application of the 6LoWPAN protocol can significantly improve the battery life of the data collection node, reduce power consumption, increase the current transmission rate, and improve Success rate of voltage over-limit switch control. The application of 6LoWPAN protocol can effectively improve the level of safe operation of the power grid.
