Study on Dynamic Characteristics of Train-bridge Coupling Based on Wireless Sensor Network

Nianchun Deng,

Abstract


It is very important to monitor dynamic responses and health states of the bridge in time and avoid occurrence of bridge collapses accidents. The bridge span is relative large, so detected positions should be scattered, and sensors should be placed on multiple cross sections. In traditional dynamic response tests of bridges, data collection is generally based on the wired type which is deficient in inconvenient installation and wiring. Aiming at those defects, this paper applies WSN (wireless sensor networks) technologies to test dynamic responses of a bridge under train effects. The WSN is a network system formed through a wireless communication type. It could sense, collect and process information of sensed objects in a network coverage region in a collaborative manner, and could send the information to users of the network through wireless transmission. Finally, through comparing with those results of wired sensors, reliability of tested results in the paper and validity of network layout were verified.
