摘要：Recently wireless sensor networks for structural health monitoring are the hotspots of academic and engineering circles both at home and abroad. The bridge is an important part of the transportation system, and the safe operation of the bridge is related to the safety of life and property of the people and the development of the country's economic construction. Therefore, it is of great theoretical and practical significance to carry on health monitoring for the structural damage to the bridge. This paper proposes a CIRF based on constructive interference for wireless bridge health monitoring system. The flooding protocol adopts RI-MAC mechanism and makes full use of multiple nodes to send data of the length of interference. The simulation results show that CIRF can effectively reduce the flooding delay, reduce the node energy and improve the packet delivery rate. The experimental results show that the damage detection method proposed in this paper is effective, and the design system has great improvement and it is of great significance for research.
