The present invention relates to a technique related to a management system for physically weak people through abnormality of a bio-signal, which makes it possible for physically weak people such as infants, elderly people or disabled people to respond promptly to an emergency. The management system for physically weak people through abnormality of a bio-signal comprises: a wearable means that can be attached to a body of physically weak people such as infants, elderly people or the like； a beacon signal generator that is embedded in the wearable means to generate a unique identification number； a biometric information scanner that is embedded in the wearable means to check biometric information such as blood pressure, pulse, body temperature and the like of the physically weak people and that can generate an emergency signal when biometric information exceeding a range set based on the biometric information in a normal state is generated； a wireless communications module that is embedded in the wearable means to transmit the emergency signal provided by the biometric information scanner； a server that can transmit the emergency signal to a registered protector group by receiving the emergency signal transmitted from the wireless communications module and that can receive trace request information requested by a protector who receives the emergency signal first； and at least one beacon signal repeater that can receive the beacon signal provided by the beacon signal generator and that provides location information on a position where the beacon signal is generated by the trace request information transmitted from the server.본 발명은 영유아나 고령자 혹은 장애자와 같은 신체적 약자의 위험상황시 신속한 대처가 가능하도록 하기 위한 생체신호 이상유무를 통한 신체적 약자 관리시스템에 관한 기술로서, 유아나 노약자 등 신체적 약자들의 몸에 부착할 수 있는 웨어러블 수단； 상기 웨어러블 수단에 내장되어 고유한 식별신호를 발생시키는 비콘신호생성기； 상기 웨어러블 수단에 내장되어 상기 신체적 약자의 혈압, 맥박, 체온 등의 생체정보를 체크할 수 있으며, 정상상태일때의 상기 생체정보를 기준으로 설정된 범위를 넘어가는 생체정보가 발생되는 경우 비상신호를 생성시킬 수 있는 생체정보스캐너； 상기 웨어러블수단에 내장되어 상기 생체정보스캐너가 제공하는 비상신호
