摘　　要：为有效提高光纤传感网络自修复效果,提出一种环境自适应的光纤传感网络自修复方法。依据光纤传感网络自我监测需求,构建由传感层和数据处理层组成的环境自适应的光纤传感网络智能监测结构,数据处理层利用随环境变化而自行切换调整的光开关策略,与自修复结构中多主体之间进行相互协作,实现对失效FBG传感信号的监测和自修复,并通过自修复数学分析详细剖析光纤传感网络的自修复过程。仿真实验结果表明,该方法具备更好的光纤传感网络监测和自修复能力,修复后的光纤传感网络流量通行能力较强,中间无阻碍流量通行的链路和节点故障,通行过程顺畅,链路故障修复平均耗时仅为1.03 ms。In order to effectively improve the self-repair effect of optical fiber sensor networks,this paper proposes an environment adaptive self-repair method for optical fiber sensor networks.According to the self-monitoring requirements of optical fiber sensor network,an environment adaptive intelligent monitoring structure of optical fiber sensor network is constructed,which is composed of sensing layer and data processing layer.The data processing layer uses optical switch strategy that can be switched and adjusted according to the change of environment,and cooperates with multi-agent in self-repair structure to realize the monitoring and the self-repair of failed FBG sensor signal.The self-repair process of optical fiber sensor network is analyzed in details through self-repair mathematical analysis.The simulation results show that the method has better monitoring and self-repair ability of optical fiber sensor network.The repaired optical fiber sensor network has stronger traffic capacity,and there is no link and node fault blocking traffic in the middle.The traffic process is smooth,and the average time of link fault repair is only 1.03 ms.
