Design of Lavatory Emergency Detection System

열차화장실 내의 응급상황 감지시스템 설계에 관한 연구

If an urgent situation, such as a stroke, faint, heart attack, happens in a lavatory, it is hard to recognize and perform an immediate emergency treatment unless the patient inside of the lavatory calls for help. If a system that can detect an emergency in a lavatory and report to the relevant personnel is developed, it would be an excellent installation case demonstrating how a train is nicely designed to take care passenger's safety. In this paper, we showed a design of lavatory emergency detection system (LEDS) that detects an urgent situation in a lavatory by using sensors and timers and reports to proper personnel. This system can be installed not only on a train but also in a building where visual monitoring is not possible.
