초록

본 논문에서는 특수 작업자들의 생체신호(심박, 체온, 심전도, 근전도)와 추가적인 상황정보(3축 가속도, 온도, 습도, 조도, 주변 영상)를 획득하고 모니터링 할 수 있는 직물형 플렉시블 플랫폼 기반의 다중 생체신호 중앙 모니터링 시스템을 구현한다. 이 시스템은 원격지에서 작업 환경 내에 발생할 수 있는 각종 사고를 예방하고 작업자가 처해있는 상황을 실시간으로 인지하여 조속하고 효율적인 조치를 취할 수 있다. 이를 위한 직물형 플렉시블 플랫폼은 생체신호와 상황 정보의 획득이 작업자의 관련 업무 수행에 방해가 되지 않게 하기 위해 이너웨어 또는 아웃웨어 형태로 제작하였고, 획득된 정보들은 무선 통신을 이용하여 중앙 모니터링 시스템에 전송 가능하도록 하였다. 중앙 모니터링 시스템은 WMTS(Wireless Medical Telemetry Service)의 의료전용 무선통신을 기반으로 최소 2명에서 부터 32명까지 동시에 모니터링 할 수 있으며, 추가 확장 가능한 구조로 설계 하였다. 또한 본 논문에서는 제작된 WMTS 통신 모듈의 성능을 검증하기 위하여 거리에 따른 패킷 수신율을 비교하여 분석하였다.

The purpose of this paper is to implement a multiple bio-signal central monitoring system based on textile fabrics flexible platform which can obtain and monitor bio signals(heart rate, body temperature, electrocardiography, electromyogram) of workers in special working environments and additional situational information (3-axis acceleration, temperature, humidity, illumination, surrounding image). This system can prevent various accidents that may occur in the remote work environment and provide fast and efficient response by detecting workers' situations in real-time. For it, the textile fabrics flexible platform was made as innerwear or outerwear so that it does not interfere with workers' performance while collecting bio-signal and situational information, and obtained information is sent to the central monitoring system through wireless communication. The central monitoring system is based on wireless medical telemetry service of WMTS (Wireless Medical Telemetry Service); can monitor from 2 to 32 people simultaneously; and was designed so that it can be expanded. Also, in this study, to verify performance of the WMTS communication model, packet transmission rates were compared according to the distance.
