Research And Realization Of Intelligent Node In The Building Electrical Equipment Internet Of Things

The rise and development of Internet of Things technology provides an effective way to realization of the building intelligent and unified management of electrical equipment. Building Electrical Equipment Internet of Things includes WEB technology, Ethernet technology and wireless network technology. As the core device of Building Electrical Equipment Internet of Things, The intelligent node is a bridge and link to connect the Ethernet server and the underlying equipment. With the comprehensive development of the networking industry, people pay much more attention to the safety of data transmission. The protection of network privacy and data security among the communication process has become an important issue to be solved. Meanwhile, the research of the data processing method which is uesd to meet the data characteristics that species complex, rich semantics, and data real-time transmission in Internet of Things is also important. The intelligent node of the data encryption, data processing and intelligent management of equipment are carried on in-depth study. The research is listed as follow:First, the overall structure and function of each layer of the Building Electrical Equipment Internet of Things System are analyzed, and the function of the intelligent node is introduced in detail.The overall structure of intelligent node hardware is designed. Secondly, the improved lightweight DES encryption algorithm is chosen to realize the encryption of intelligent node data. According to the problem of the DES algorithm key space and the intelligent node with limited space resources, the DES encryption algorithm is improved lightweight based on Logistic chaos system. The improved encryption algorithm is applied to the embedded system of intelligent node. And the intelligent node realizes data encryption and decryption function by software. Thirdly, the data processing of intelligent node is researched. The research includes data collection, event classification and data storage and data priority allocation. The intelligent node completed the data processing through the Software. The model of room electricity consumption which can realize prediction and analysis of electricity in room is established. Finally, the performance of the intelligent node is tested in the Building Electrical Equipment Internet of Things System.The test results and application effects show that the intelligent node has excellent performance, stable and reliable running, as well as convenient system operation. Building Electrical Equipment Internet of Things Management System has practicability and humanized design meeting user requirements.
