Abstract: In recent years, the safety problem of urban bridge was becoming more and more serious in construction and operation stage, and the intelligent monitoring system of urban bridge was an effective means to improve the safety management level of urban bridge. The background and composition of urban bridge intelligent monitoring system was studied in this paper. The development history and research status of urban bridge intelligent monitoring system was discussed. Moreover, the progress and shortcomings of current research in sensing equipment, data transmission and monitoring system were summarized. In view of the current research defects, combined with wireless sensing, edge computing, artificial intelligence, BIM and other new technologies, the future development direction of urban bridge intelligent monitoring system in construction and operation stage was proposed, which could provide reference for relevant research.
