Wireless sensor networks for underground railway applications: case studies in Prague and London
Peter J. Bennett,Kenichi Soga,Ian Wassell,Paul Fidler,Keita Abe,Yusuke Kobayashi,Martin Vanicek 국제구조공학회 2010 Smart Structures and Systems, An International Jou Vol.6 No.6
There is increasing interest in using structural monitoring as a cost effective way of managing risks once an area of concern has been identified. However, it is challenging to deploy an effective, reliable, large-scale, long-term and real-time monitoring system in an underground railway environment (subway / metro). The use of wireless sensor technology allows for rapid deployment of a monitoring scheme and thus has significant potential benefits as the time available for access is often severely limited. This paper identifies the critical factors that should be considered in the design of a wireless sensor network, including the availability of electrical power and communications networks. Various issues facing underground deployment of wireless sensor networks will also be discussed, in particular for two field case studies involving networks deployed for structural monitoring in the Prague Metro and the London Underground. The paper describes the network design, the radio propagation, the network topology as well as the practical issues involved in deploying a wireless sensor network in these two tunnels.
