The Ubiquitous Power Internet of Things Based on Dynamic and Reconfigurable ROF Technology

摘要

With the construction of " Ubiquitous Internet of Things in Power System", the transmission of power information data is put forward higher requirements for power communication network. In this paper, a ubiquitous internet of things in power system based on dynamic and reconfigurable ROF technology is proposed based on the current construction situation of power communication network. This system adopts ROF technology to transform the base station architecture of cellular mobile communication network into the compound of remote antenna unit(RAU) that closes to users and the central office(CO). At the same time, in order to cope with the increasingly complex situation of terminals wireless access, an information transmission network based on dynamic and reconfigurable ROF technology is proposed by tunable filters, which can achieve flexible conversion of signal modulation and dynamic switch of multi-frequency. This technology can improve the utilization rate of spectrum resources, realize dynamic control of bandwidth resources, and provide communication network with low cost, wide bandwidth, flexible networking and reliable transmission for ubiquitous internet of things in power.
