| 摘 要： | 提出了一种基于以太无源光网络(EPON)的光纤布拉格光栅(FBG)传感网络多传感通道切换控制方案。控制传感通道切换的多个光开关分别与EPON系统中的多个光网络单元(ONU)相连,利用各ONU间严格的时间同步特性在各ONU控制下实施对多个光开关的同步切换控制,实现各FBG传感通道与传感解调模块间的有序连通。实验结果表明,此方案的稳定性较好,并且具有较灵活的扩展特性。

| Abstract: | A switching control scheme of multiple sensor channels in distributed fiber Bragg grating sensor network is brought forward based on Ethernet passive optical network(EPON),in which the optical switches of multiple sensor channels are controlled by different optical network units(ONUs) in one EPON system.As a result,all of the optical switches could execute switching synchronously based on the strict time synchronization in the EPON system.Therefore,the wavelength demodulation module and different FBG sensor... |
