Abstract: The management information of dam safety is not comprehensive enough and the data is not fully visible. In view of this, we employed the Internet of Things technology to construct an information perception system covering the dam’s air, ground surface, interior and underwater spaces. Faced with the technical difficulties of massive terrain scheduling, dam and terrain inlay, and the expression of safety information in three-dimensional space, we designed a dam safety management platform integrating the Internet of Things technology and 3D visualization technology to display dam safety information in real geography. The rapid, efficient and intuitive display of space provides managers with a means to quickly obtain dam safety status, improve the dam safety management level, and overcome the shortcomings of intelligent dam safety management in the field of information technology.

Key words: dam safety management platform, Internet of Things, three-dimensional visualization technology, dam safety information, intelligent watershed
