Abstract: The application of the internet of things technology (IOT) brings opportunity for modern dam safety intelligent inspection. Aiming at the present situation of reservoir dam safety inspection data， information island serious deficiencies and poor timeliness problem， this paper introduces intelligent internet of things technology in the dam safety inspection， combined with traditional inspection methods， and puts forward the method to check the internet information organization and inspection index as an object to carry out studies of the perception and fusion architecture and composition of the intelligent inspection system， and probes into the construction index system of dam safety inspection， information fusion and revision work instructions， etcand the key technology of system development. An intelligent inspection system is developed based on the internet of things and the main function of the system in combination with Yanshan reservoir dam works is summarized. The establishment of the system is of significant and practical value for improving the reservoir safety management. And the system is well worthy of application and promotion in the similar reservoir dam works.
