In the present invention, the conventional technology merely confirms the location of the user only, and there is no portable equipment for confirming the individuals identity at the time of the occurrence or disappearance of the lost person, and it takes a long time to confirm the identity and the cost is also high, Patients, mentally handicapped children, and preschoolers of infants who do not know when they are sick or in the event of a catastrophic accident can not be automatically notified to a centralized server located at a nearby smart device or remote location. The smart display module 200, the blood pressure sensor part 300, the short range communication module 400, the battery part 500, the GPS reception module 600, A wired / wireless communication module 700, and a smart control unit 800, and is formed in a band-like structure so as to be detachably attached to a users body, And can be worn at all times, so it is possible to prevent secondary accidents in advance by prompt identification even in case of accidents such as missing or missing persons, The personalized identification information data, the blood pressure measurement data, the position information data, and the emergency rescue signal data which can confirm the individuals identity at the time of an emergency can be automatically selected in a short distance It is possible to request rescue signals from smart devices of family members and centralized control server located at a remote location, which can improve survival rate by 80% compared to existing ones. NFC communication without battery consumption even if battery capacity is insufficient, It is difficult to structure the personal identification information data, The present invention aims at providing a convergent smart wearable device capable of selecting a customized module to be provided and transmitting an automatic emergency response signal.본 발명에서는 종래 기술이 단지, 사용자의 위치만을 확인시켜줄 뿐, 미아발생 및 실종시, 개인신원을 확인할 수 있는 휴대용 장비가 없어, 신원확인하는데 장시간 소요되
