Failure Evaluation and On-line Monitoring System Study of Underground Refuge Chamber System
In order to realize the linkage between safety management and disaster emergency in under-ground refuge chamber,the system function can be prevented from failure.Fault tree is used to quantitative-ly analyze the causes of chamber failure and the internal relations of each subsystem.Combining with engi-neering practice,the failure experience formula of chamber system is deduced,and the failure evaluation and early warning model is established.According to the spatial distribution characteristics of ground and underground,the"dual network+dual system"cooperation architecture model and the iot architecture of the monitoring system are proposed.Set up a one-stop command and dispatch line,two-way video and voice facilities to ensure the online monitoring and emergency network security of the system,and expand the scope of system collaboration.According to the early warning model,six functions of the system software are designed,the monitoring and emergency application of the system are improved,and the information ex-change between the ground and the underground is realized safely and smoothly.The monitoring system has been successfully applied in a mine in southwest China,which is conducive to reducing the occurrence of refuge chamber failure events,reducing the workload of safety inspection,improving the efficiency of opera-tion and maintenance management,and enhancing the intelligent level of mine safety management.
