Research on Intelligent Building Environment Control and Automation System Based on Internet of Things

This paper studies the intelligent building environment control and automation system based on the Internet of Things (IoT), aiming at improving building energy efficiency, reducing carbon emissions, and improving users' comfort and safety. Firstly, the development trend of intelligent building and the key role of IoT technology are analyzed, and then a four-layer architecture system design is proposed, including perception layer, network layer, platform layer and application layer. The sensing layer is responsible for monitoring environmental parameters and equipment status, the network layer transmits data through wireless communication technology, the platform layer processes data and formulates control strategies, and the application layer provides user interaction interface. In the realization of key technologies, the sensor network is designed, and various sensors are used to collect environmental data, and the accuracy of data is ensured by optimized data collection and processing algorithms. PID control, fuzzy control and genetic algorithm are considered in the design of automatic control strategy and algorithm to realize intelligent adjustment of building environment. The experimental results show that the system can significantly reduce energy consumption and improve the accuracy of environmental control and the comfort of users.
