Abstract：
According to the characteristics of the shield tunnel segment prefabrication process, the modern "Inter? net of Things" information technology is used to construct the segment IoT platform and develop a prefabrication management system for shield segments by means of radio frequency identification (RFID), QR code, sensor, scanner, intelligent integrated machine and other information sensing devices. It realizes the real-time acquisition and optimization analysis of the quality and production information data during the whole segment production process.Meanwhile, it combines the automatic production equipment with the IoT information platform of segments through the program-controlled instrument such as the industrial PLC, realizes the optimal control of segment production and the equipment through the big data analysis and optimization technology of the platform, making the production more intelligent and digital. The research and application of this technology will have a positive and far-reaching impact on the production management and quality control level of the segment prefabrication.
