A remote health monitoring platform and application method for steel structures based on the Internet of Things

Abstract

The invention discloses a steel structure remote health monitoring platform and an application method based on the Internet of Things, relating to the field of data processing, including: a data acquisition unit arranged at each point to be measured; communicating with the data acquisition unit through a 5G data receiving and transmission module The connected cloud platform system; the remote monitoring unit connected with the cloud platform system communication; wherein, the data acquisition unit is configured to include: a plurality of sensor groups matched with each point of the steel structure to be measured; each sensor is provided with a 5g IoT card for communication. The invention provides a remote health monitoring platform for steel structures based on the Internet of Things and an application method. The remote health monitoring platform for steel structures based on the Internet of Things can realize automatic, real-time, remote, and intelligent early warning of adverse conditions for large-scale steel structures. monitor. It greatly saves labor costs and the efficiency of daily inspection of engineering structures, and provides a strong guarantee for the safe service of structures.

Description

technical field [0001] The invention relates to the field of data processing, and more specifically to an Internet of Things-based steel structure remote health monitoring platform and an application method. Background technique [0002] With the rapid development of our country's economy, remarkable achievements have been made in the field of civil engineering, and various large and complex structures continue to appear. Today's civil engineering structures are developing in the direction of oversized and complex, such as large bridges, super high-rise buildings, huge stadiums and theaters with different shapes, large dams, nuclear power plants and offshore structures. However, the design service life of such major engineering structures is as long as decades or even hundreds of years. Under the joint action of disaster factors such as environmental erosion, material aging, long-term effects of loads, and fatigue effects, it will inevitably lead to structural damage. Accum...

Problems solved by technology

And at the same time, it is impossible to accurately check the stress change, displacement change, surface corrosion degree of the steel structure, whether the bolt connection is firm, etc. through the visual inspection of the personnel.

The traditional steel structure detection method uses wired data acquisition. Although this method has the advantages of stable and reliable data acquisition and little influence from noise, the tedious wiring work requires a very large cost, and the existing steel structure is healthy. The research on monitoring technology in the field of steel structures has always focused on the sensing of signals and the collection, transmission and statistics of various structural data. Or the owner’s request for simple comparison), grasping the service status of the structure, and obtaining a comprehensive evaluation of the health status are lacking, which means that only half of the work of structural health monitoring has been completed.
