Abstract: Based on the framework of Internet of things with three dimensions such as data perception layer, transport layer and application layer, and combined with characteristics of demand for the power and environment monitoring, the paper put forword three layer model of the power and environment monitoring system for Internet of things. A specific design case was also given with analysing the content of monitoring requirement and dedigning the function of central processing machine. Ultimately, the paper provided design layout for monitoring room and operation room. The model and design case give the reference value for enterprises' implementation of some feasible power and environment monitoring systems based on Internet of things.
