The Internet of Things, which began by connecting sensors through a network, is developing into an intelligent IoT by combining it with artificial intelligence technology. Elevators are essential for high-rise buildings in the city, and elevators move from floor to floor and perform the functions of transporting goods and moving users. It is necessary to provide safe and convenient services for elevator users in high-rise buildings or special environments (hospitals, etc.). In an environment where rapid patient transportation is important, such as large hospitals, there is a problem that hospital staff and the general public often use the elevator for patients. In particular, when moving patients where golden time is important, the waiting time to board the elevator is a major hindrance. In order to solve this problem, this study proposes an intelligent IoT system for elevator calling using smartphone Bluetooth. First, we experimented with the elevator calling IoT system using smartphone Bluetooth, and as a result of the experiment, it was confirmed that it can authenticate elevator users and reduce unnecessary waiting time for boarding. In addition, we propose an intelligent IoT system that connects with intelligent IoT.

최근 산업의 고도화에 따른 건물의 고층화로 하나 또는 그 이상의 승강기를 보유한 건물들이 증가하고 있다. 이러한 건물에서 화재와 같은 긴급한 재난 발생 시 피난계단을 이용하여 탈출해야 한다는 상식에도 불구하고 본능적으로 승강기를 이용하여 대피하려는 경향이 뚜렷하다. 화재상황에서 승강기 이용 시 독성의 연기 유입으로 피난 활동이 어려우며, 전원 차단으로 정지 시 연기에 질식사할 확률이 급증한다. 따라서 승강기 내부로의 고립이나 승강기를 이용한 피난활동 시 연기로부터 안전한 호흡장치의 개발을 위한 연구를 진행하고자 한다.

(주)엠투엠테크는 승강기 산업분야에서 IoT 기반 스마트 디바이스를 개발 중인 스타트업 기업이다. 특히, 윈격진단, 포렌식 기능 등 확장된 관제서비스가 가능한 스마트 디바이스 개발에 주력하고 있다. 하나의 디바이스가 다양한 제조사의 승강기에 적용되려면 승강기의 주요 부품, 디바이스, 관제 센터 간의 표준화된 통신 체계가 필요하며, 기존 승강기의 안전을 담보할 수 있는 시스템 유지 관리 체계가 구축되어야 한다. 미래에는 전체 스마트 디바이스로의 연결을 더욱 확대하여 궁극적으로 스마트 빌딩, 도시로의 적용 역시 가능하게 할 단계적 진화 모델의 고려가 필요한 것도 물론이다. (주)엠투엠테크가 TIA의 중소 중견기업을 위만 표준 자문서비스를 신정만 것은 이 때문이었다. (주)엠투엠테크는 TTA 표준 자문전문가들과 함께 국제 표준을 기반으로 한 IoT 프로토콜을 적용해 제품을 업그레이드할 수 있는 시스템 아키텍처를 설계할 수 있었다.

Domestic elevator accidents which are related to human life such as death are occurring steadily. This research measured and analyzed for the quality of power source which has possibility to be associated with fault and malfunction of elevator equipment although it is not direct cause examination. In conclusion, we acquired the result that there is possibility that the quality of power source(Sag, Interruption, Harmonic, Electromagnetism emission waveform, Static electricity etc) has an effect on movement of elevator through examination of three elevator facility models and suggested measures for it. Accordingly, this research result will be used as data to suggest establishment of elevator examination regulations and KS regulations for domestic elevator industry and the least safety of household using elevator.

The purpose of this study is to derive education programs for safety training class, create unit spaces and present components and methods of utilizing the spaces for the development of facilities models closely related to various policy, operation plan and facility construction projects promoted by related institutions such as the Ministry of Education, schools, architects and companies. This study is divided into five steps. First, we reviewed the literature related basic directions for safety education and facility plan, second, field survey included both field conditions such as spatial size and facility configuration and analysis of operating conditions like hours of operation and personnel. Base on literature review and field survey, it were used to analyze strengths and weaknesses of existing safety training classes, and five facility models was developed based on the Delphi method and expert participatory design. The result show that the facility models (drafts) of safety training class were developed as follows: (1)the facility model for traffic safety(pedestrian safety, vehicle safety, subway safety) (2)the facility model for first aid(emergency rescue, how to report) (3)the facility model for disaster safety(fire evacuation safety, life earthquake safety) (4)the facility model for elevator safety(elevator safety, escalator safety) (5)the facility model for drugs and violence safety (smoking drinking, sexual harassment safety, food safety) The safety training class can be composed by combining or separating each module according to affordable space size of each school.
