Development of Wireless Sensor Node and Field Application of Long-span Bridge using Ubiquitous Technology

유비쿼터스 기술을 이용한 무선센서노드 개발 및 장대교량 현장적용 검증 실험

As economic rapid growth, large structures are damaged by defects from design and construction process of the formation and environments. Therefore, safety diagnosis and monitoring skills are bringing importance into relief and legislate for safety diagnosis of large structures. However, the existing monitoring systems are difficult by using wire cable because of cost, error of date, location, revise. In this paper, wireless sensor network which are accelerator, temperature sensor system using ubiquitous had been field test on Sea-Hea Grand bridge. We compare accelerator, temperature sensor system with wire and wireless sensor network.
