Air-conditioning fault diagnosis system and methods based on Internet of things and data fusion
基于物联网和数据融合的空调故障诊断系统及方法*

To solve the problem that the models of the traditional fault diagnosis methods are difficult to establish precisely, this paper designed an air-conditioning fault diagnosis system based on Internet of things and data fusion. In this paper, firstly, proposed the architecture of the air-conditioning fault diagnosis system, and also introduced some key technologies of implementation. Then, presented some data analysis methods and some comprehensive diagnosis methods used in this system. Finally, also gave several applications of this system. The fault diagnosis system could monitor the operation status of the air-conditioning equipments. It also provided analysis and judgment of the data in the database, and took appropriate decisions to achieve the fault diagnosis purposes of the air-conditioning equipments in the Internet of things.
