摘要
文章提出了光纤通信网与传感网融合的设想,即利用已有光纤接入网的通信信道,让传感网络发出的传感信号在光纤接入网中传输。首先分析了这种设想的可行性,然后提出了按固定帧复用的方式对传感信号和通信信号进行耦合,并根据已有光纤接入网的结构建立了该系统的网络基本结构,重点分析了传感信号与通信信号复用时的时隙及带宽分配问题。
In this paper, a tentative idea on the convergence of fiber-optic communication networks with sensor networks is presented, i.e. transmitting the sensor signals delivered in the sensor networks in the channels of the existing OAN. It first analyzes the feasibility of this idea. Then it puts forward a method for the coupling of sensor signals with communication signals according to that for the fixed frame multiplexing, sets up the basic network architecture of this system according to that of the existing OAN and analyzes the time slot and bandwidth allotment in the above-mentioned multiplexing.
