Recently, needs of recreational marine industry are consistently increasing due to increasing of income and pursuit on well-being. For these needs, central government and local governments have tried to build tens of marinas to meet demands and promote related industries. Therefore, need of smart pedestal system has also increased. However, domestic companies have not manufactured smart pedestal systems, so many pedestal systems have been imported from advanced countries such as England, Denmark, and Italy. This research has developed a smart pedestal system using IT convergence technology. This system is assembled by each several module which has its own function and board. Each module is not developed on an embedded OS. Instead, it has its customized operational software based on its kernel. Thus, this system brings about cost reduction of productions and maintenance.
