摘要
针对目前电力通信网网络资源现状及技术体制特点,结合电力物联网需求,提出基于物联网、以太网无源光网络(Ethernet Passive Optical Network,EPON)和同步数字传输(Synchronous Digital Hierarchy,SDH)技术的组网方案,并对物联网安全体系建设进行了分析。结果表明:完善的SDH网络和基于城区配电通信需求的EPON通信网络能够满足城市配电物联网的相关应用。
Aiming at current network resources status quo and technological characteristic of the power communication network,and combining with the demands of power internet of things,puts forward the network scheme based on internet of things and Ethernet Passive Optical Network （EPON）technology,and Synchronous Digital Hierarchy （SDH）technology,analyzes safety system construction of internet of things. The result shows that the perfect SDH network and EPON communication network based on urban power distribution communication system can satisfy the relevant application of internet of things for urban power distribution system.
