Application Study of UAV and IOT Technology in Intelligent Detection of Bridge Engineering

Abstract

The ministry of transport officially released the implementation plan for the construction of highway long- span bridge structural health monitoring system on march 1, 2021, which is doomed to promote the popularization and application of bridge structure health monitoring. This paper innovatively combines UAV(Unmanned Aerial Vehicle) and IOT(Internet of Things) technology, and carries out practical engineering application in bridge quality detection project. Firstly, based on the research status of bridge health monitoring, the design principles, reference laws and code of intelligent bridge inspection system are sorted out, and a three-layer intelligent bridge detection system based on IOT is designed. The main components include low-power consumption wireless sensor, edge data acquisition device, gateway and health big data analysis center. This paper focuses on the practical application of UAV and IOT technology in intelligent detection of bridge engineering. The innovations include targeted deployment and monitoring of various types of sensors according to the actual bridge structure and on-site conditions, as well as targeted design of UAV flight routing and important detection sites. Finally, this paper discusses the research status of bridge structural damage identification and health status assessment. Although some progress has been made, there are still many difficulties to be overcome for practical engineering applications. Through the introduction of the above practical engineering application cases, it is hoped to provide some guidance for the research of bridge health monitoring and intelligent detection.
