Application for Measurement of Curing Temperature of Concrete in a Construction Site using a Wireless Sensor Network

As the construction industry has recently been transformed by the emergence of ubiquitous and intelligent technology, there have been major changes in the management met hods employed. Specifically, next-generation construction management systems have been developed that collect and analyze many pieces of information in real time by using various wireless sensors and networks. The purpos e of this study is to understand the current status of Ubiquitous Sensor Networks (USN) in the construction sector, and to gain fundamental data for a system of measuring concrete curing temperature in a construction site that employs a USN. By investigating the application status of USN, it was confirmed that USN has mainly been applied to the maintenance of facilities, safety management, and quality control. In addition, a field experimen t in which the curing temperature of concrete was measured using a USN was carried out to evaluate two systems wi th wireless sensor networks, and the applicability of these systems on site was confirmed. However, it is estimate d that the embedded wireless sensor type is affected by metal equipment on site, internal battery of sensor and conc rete depth, and studies to provide more stable system by USN are thus required.Keywords : ubiquitous sensor network(USN), curing temperature, concrete construction, wireless sensor
