Monitoring and Analysis of Human Activities Using Heterogeneous Sensors in the Gas Room of a Hospital

Abstract

Every hospital relies on the gas pipeline system. There are common three types of gases are used: oxygen, nitrogen, and nitrous oxide. Each type of gas is critical in many departments, including the operating room and intensive care unit. Gas room administrators, such as engineers or hospital personnel, are just as important as gas rooms. If something happens to engineers or personnel, an unattended gas room may malfunction and cause trouble in the hospital. Therefore, we proposed a monitoring system with a human activity surveillance project using accelerometer sensors, video images, and gas sensors. This system can collect all the signals used for the analysis of the posture or activities of the personnel who examine the gas in the gas room. We also developed surveillance in the event of an unexpected event in the gas room.
