Study on Cable Monitoring System Based on Mesh Network Robustness Optimization

电缆隧道由于空间密闭、管线密集,内部环境复杂,易出现监控节点损坏等情况,进而产生应急抢险工作时的监控盲区。因此,文中研究分析了当前应急监控系统的研究现状,提出并设计了一种Mesh网络架构鲁棒性优化的应急无线监控系统,具有高可靠性、自组织自恢复特性的特性。文中首先阐述了该监控系统的设计思路以及整体框架,通过仿真验证了所提出的链路重建策略的有效性,现场通信测试表明,该系统在链路突变时能够快速恢复,具有很强的网络生存能力。

The cable tunnel is susceptible to damage of monitoring node due to airtight space,dense pipelines and complicated internal environment,leading to blind spots in emergency rescue work.Therefore,in this paper,the study status of present emergency monitoring system is studied and analyzed,a kind of emergency wireless monitoring system with optimized robustness of Mesh network architecture is proposed and designed,which has such characteristics as high reliability,self-organization and self-recovery.The design idea and overall framework of the monitoring system are described firstly;the effectiveness of the proposed link reconstruction strategy is verified by simulation.It is shown by the field communication test that the system can recover quickly in case of link mutation and has a strong network survival capability.
