An Accident Notification System in Concrete Pouring using Sound Analysis

In this study, a sound analysis-based detection and reporting system for accidents that occur during concrete pouring is proposed. First, the process of the existing monitoring system was examined and problems were noted, and studies and technical approaches to sound analysis were analyzed. Pouring sound samples were then collected from construction sites, the frequencies and patterns were identified, and accident sound patterns were created by superimposing leakage and other noise onto pouring sound samples. Finally, logic and an algorithm to identify accidents were proposed based on the results of patterns retrieved from the above datasets. In the future, it is expected that accident notification systems using the sound analysis proposed in this study will be useful not only for the prevention of accidents but also for safety management throughout construction sites in general.
