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.
