摘要(Abstract):
现有的电力通信协议难以满足新型配电物联网数据交互的时效性和可靠性要求,也难以满足高精应用差异化的服务质量要求。针对上述问题,分析了以数据为中心的DDS(数据分发服务)的技术特点,并通过仿真实验与常见物联网协议进行对比,发现DDS在实时性、安全性、可靠性方面均有较好的性能指标,进一步设计了基于DDS的开放式配电物联信息架构,以期满足新型配电物联网数据交互的要求。
The existing power communication protocols can hardly meet the requirements of timeliness and reliability of data interaction in the new power distribution Io T,and the requirements of differentiated service quality for high precision applications.To address the above problems,the technical characteristics of data-centric DDS(data distribution service)are analyzed,and the DDS,through simulation experiments,is compared with common Io T protocols.It is found that the DDS has better performance indexes in respect of instantaneousness,security,and reliability,and the open Io T information architecture based on the DDS is further designed to meet the requirements of new distribution IoT data interaction.
