Real-Time heart rate monitoring system for construction site workers using wearable equipment

Abstract

This study aimed to minimize harm to construction workers by proposing a method to monitor their physical condition on construction sites using wearable equipment, a smart technology. As a research method, workers with the highest risk among construction workers at building sites were divided into three age groups: Group 1 (20-35 years old), Group 2 (36-51 years old), and Group 3 (52-65 years old). The average heart rate, work intensity, and cumulative fatigue were measured for 21 days. In addition, the Carbonen formula was used to determine the work intensity, and the calculated daily and cumulative calorie consumption were used to express cumulative fatigue. By applying smart technology to construction sites, the current status of workers could be identified quickly, enabling an immediate response in the event of a disaster. In addition, cumulative fatigue could be confirmed, making it possible to identify a continuous condition rather than a one-off condition. Using the formula for replacing the heart rate, this paper presents results that can confirm the worker's cumulative fatigue. Even users unfamiliar with heart rate analysis can easily access and understand the results.
