Abstract

As with the recent earthquake in Turkiye, there is a lot of concern about earthquakes around the world. Korea is also on the rise in the frequency of earthquakes and is not an earthquake-safe country. Therefore, the importance of systems that monitor seismic design, damage, and internal cracks of buildings is increasing. Damage to the inner wall of a facility due to external factors such as earthquakes can be visually confirmed, but it is difficult to diagnose damage because it includes invisible inner wall or wall damage. One of the methods that can be monitored quickly when a building collapses due to a disaster or disaster is to use a smart sheet for damage detection. Damage to the structure of a building can be caused by various factors such as natural disasters, aging, or poor construction practices, which can lead to loss of life or property in the event of a building collapse. In addition, existing monitoring systems have limitations in detecting structural damage in the early stages, rely on sensors installed at specific locations, and can only detect damage in the area.Therefore, it may not be detected until damage to other parts of the building has progressed. In order to solve this problem, it is possible to collect and respond to the state information of the building in real time by using a sensor attached to the wall of the building and a crack detection tape to detect damage caused by natural disasters or structural defects of the building. It can also detect changes in the orientation of building walls or other physical parameters that may indicate damage, and provides accurate information to sensor nodes to detect damage in any part of the building. In this paper, we propose a damage detection monitoring system using the direction information of the wall sensor node to overcome these limitations.
