摘要
具有实时应急功能的无线传感器网络是解决施工隧道安全运营的有效手段之一。针对施工隧道的环境恶劣、事故多发等特殊应用背景,提出一种紧急状况下多层次跨层联动的应急通信协议,保障网络对突发状况能快速重构。实验结果表明,提出的应急通信方案用于故障恢复和拓扑结构动态变化的网络具有实时性好、可靠性高等特点,适合于施工隧道的监测网络,也可推广到其他有应急需求的网络。
Wireless sensor network with the characteristic of real-time and emergency is an efficient method to handle the problem of safety operation in tunnel construction.With the special-application background about chain-type space,severe envi-ronment,and high accident potential,a cross-layer emergency communication protocol is proposed under the condition of emergency situation to ensure a rapid reconfigurable network.For fault recovery and dynamical change of network topology, the experimental results show that the communication protocol has advantages in real-time and reliability.It is not only suit-able for tunnel monitoring system,but also can be used in any other emergency networks.
