摘要: 隧道施工中采用无线监控技术具有减少网络布线、增加系统灵活性的优点,但是现场施工环境的复杂多变性及传感器节点软硬件不稳定性会导致监控系统瞬时故障而引发安全事故。针对瞬时故障,从保障系统功能出发,建立瞬时故障层次模型,提出了一种多层次故障恢复控制策略,对现场数据监测层、数据传输层、安全防护层、应急响应层四层瞬时故障进行处理。模拟实验表明,该恢复控制策略能提高监控系统对灾害的检测准确率和应急响应动作的执行有效率,有利于保障隧道施工人员安全。

Abstract: Using the wireless monitoring technology in tunnel construction can reduce the network cabling and increase the system flexibility. But the complexity and variability of the tunnel construction environment and the instability of the sensor nodes' software and hardware often lead to the transient faults, even cause security accidents. Against the transient faults, in order to ensure the system functions, a multi-level transient fault recovery and control strategy was proposed, which dealt with the transient faults in four layers: the spot data monitoring layer, the data transport layer, the security protection layer and the emergency response layer. The simulation results indicate that the proposed strategy can improve the accuracy of hazard detection and the execution efficiency of commands execution, beneficial to ensure the safety of constructors.

Key words: tunnel construction, wireless monitoring, transient fault, safety accident, fault handling, recovery and control
