With the development of the Internet of things, architectural design and construction stages for the application of Internet of things has become indispensable.In the background of the project of Shenyang Shang Tai Department Store, based on the steel wire strain sensor and angle sensor, we studied a construction monitoring system and the analysis of monitoring data and solved the problem of data commission and acceptance.Firstly, according to the site situation we made the rational arrangement of measuring points in the vertical deflection and stress. According to the change of the structure response, after the processing of monitoring data, it can realize the reasonable control of the construction steps, so as to achieve the purpose of safe construction.
