논문 초록 (Abstract)

Sensors, equipment, ICT facilities and their corresponding software have a relatively short lifetime relative to that of constructional structure, so these devices have to be continuously fixed or exchan ged during maintenance and management. Furthermore, software or analysi s tools should be periodically upgraded according to advances in ICT and analysis technology. Conventional monitoring systems have serious problems in that it is difficult for site engineers to modify or upgrade hardware and analysis algorithms. Moreover, we depend on the original system developer when we want to modify or upgrade inne r program structures. In this paper, we propose a novel design for integrated maintenance and management of a monitoring system by applying the mobile cloud concept. The system is intended for u se in disaster prevention of constructional structures, including bri dges, tunnels, and in traditional buildings in a local heritage villa ge, we analyze the status of these structures over a long term or a sh ort-term period as well as in disaster situations. Data are collected ov er a mobile cloud and future expectations are analyzed according to probabilistic and statistical techniques. We implement our int egrated monitoring system to solve the existing problems mentioned abo ve. The final goal of this study is to design and implement a monitori ng system for more than 10,000 structures spread within Korea. Furthermo re, we can specifically apply the monitoring system presented here to a bridge made from timber in Asan Oeam Village and a traditional house in Andong Hahoe Villageto monitor for possible disasters. The entire s ystem design and implementation can be developed on the LinkSaaS pl atform and the monitoring services can also be implemented on the platfo rm. We prove that the proposed system has good performance by perfor ming a TTA authentication test, web accommodation test, a
