  • 본 논문에서는 인천공항 Airside와 Landside에 위치한 자산의 효율적인 관리를 위한 사물인터넷(IoT) 기반 스마트 자산관리 시스템의 구성과 실증을 제시한다. IoT기반 스마트 자산관리시스템은 위치정보를 생성하는 IoT 태그와 게이트웨이, 수집된 위치정보를 수신하고 표출하는 서버로 구성되어 있으며, IoT 태그를 자산에 부착하여 자산의 실내외 위치정보를 자산관리 시스템에서 실시간으로 확인할 수 있다. 실내 위치정보는 BLE(Bluetooth Low Energy)를 통해 취득하며, 실외 위치정보는 GPS와 LoRa(Long Range)를 통해 취득 가능하다. 개발한 시스템의 성능 검증을 위해 인천공항 제1여객터미널 내 기설치된 AP를 활용하였으며, 공항 전역을 커버할 수 있는 LoRa Gateway를 설치하였다. 개발한 자산관리 시스템은 공항이 보유한 자산의 도난 방지 등 효율적인 관리 와 공항운영에 기여할 것으로 예상된다.

  • 바람은 기상, 기후, 농림, 교통, 산업, 재난, 생활안전, 신재생 에너지 등 다양한 분야에서 널리 활용되는 요소 중 하나이다. 특히, 항공기 이착륙에서는 측풍의 형태가 항공기 안전에 큰 영향을 미친다. 본 연구에서는 연구지역의 기 구축된 자동기상관측장비(AWS)의 정보를 연계 구축하여, 풍향과 풍속을 1분 단위의 변화량을 반영한 실시간 바람정보 표출시스템을 개발하였다. 이를 통해 기존 문자 및 이미지 형태의 정보에서 시각화된 실시간 바람지도 제공을 통해 공항 이착륙시 항공기 안전운항에 도움이 될 것으로 기대된다.

  • Recently, the airport operator provides information such as real-time airport processing status, which allows users to determine the time to arrive at the airport at their own judgment. It is provided through their website and mobile Apps in order to resolve the customer's failure to board the aircraft and the inconvenience caused by waiting for the airport, etc. However, there was a lack of research cases on the intention of users to continue using such real-time airport information. Therefore, research on the field was studied by applying flow and trust theory based on human emotions. The research method verified reliability, validity, correlation between variables, and hypotheses using structural equations. As a result of the study, it was found that flow and trust had a significant effect on the intention to continue using. In other words, passengers were intended to continue to use the behavior they were searching for when they felt wise, enjoyable, and reliable etc.

  • A controlling system for airport refueling facilities is connected to sensors which collect various informations. Informations which are transmitted at a high speed in various sensors are processed by a dedicated software in the controlling system. The problems of system maintenance and network traffic caused by the use of dedicated software reduce the efficiency of the system operation. Therefore, a web-based system that can be accessed using the Internet environment is required. In this paper, we propose a system showing web-based real-time informations. To do this, we change the function of the communication by each sensor to a facade structure, and design a system for transferring web-based real-time informations. Also we propose data-driven infographics for displaying the real-time big data information at a high speed on the web. Finally, we compare and analyse the proposed system between the existing system and show that our system can effectively display the real-time information on the web.

  • Digital signage in airport is used to provide the flight and airport information to the airport passenger. However, the current digital signage displays one type of contents to all of the airport customers without considering the type of the customer. Thus, the digital signage suffer from the inefficiency problem resulting in lower customer satisfaction. This problem can be solved if we adopt a smart digital signage which can recognize the type of the customer and provide the tailored contents. In this study, we report a smart digital signage using age recognition. Our smart digital signage can recognize the age of the customer in real-time, and provide the tailored contents to the customer. The smart digital signage can improve the airport customer satisfaction and the airport work efficiency by providing the information that is needed by the airport customers.

  • Digital signage provides flight and airport information to the airport visitors and passengers. However, the digital signage has efficiency problem by displaying one type of advertisement to every customers regardless of their personality. We may solvel the inefficiency problem by using a smart digital signage which can recognize the characteristics of the customer We presents a smart digital signage with sex recognition function. The smart digital signage can recognize the sex of the customer to display the custom-made advertisement in realtime so that we can increase the satisfaction level of the airport passengers and visitors.

  • In recent, there has been remarkable progress in the field of GPS applications. In a few years, an appreciable number of aircraft will adopt GPS as a landing guidance system because GPS is more economic, more reliable and more accurate than any other aviation systems. In this respect, we have performed several helicopter landing flight tests based on the real-time DGPS system made in SNUGL (Seoul National University GPS Laboratory). From the experimental results, we found several problems Which should be fixed to adopt DGPS as a aircraft landing guidance system. In this paper, we will introduce the problems found in tests and also suggest modifications to solve the problems. Our modifications can be classified into three parts. The first is about the attitude determination with single GPS antenna. The second deals with the cockpit display module. The display was devised to integrate the Instrument Landing System(ILS) with tunnel-the-sky using virtual reality. With the display, pilot can achieve more safe landings. The last part is the digital map. We inserted digital map into our system and put direction indicator on the map using position information from GPS. It is very useful for pilot to find airports even in bad weather. Using the newly designed DGPS landing system, we conducted flight test at Kimhae International Airport, Pusan, Korea. It was successful! Our system can also satisfy Category-I criterion for aircraft landing approach and determine attitude angle with a high level of reliability. It is supported by video materials.

  • This paper proposes automatic precision approach radar (PAR) control system using digital signal to increase the safety of aircraft, and discrete event systems specification (DEVS) methodology is utilized to verify the proposed system. Traditionally, a landing aircraft is controlled by the human voice of a final approach controller. However, the voice information can be missed during transmission, and pilots may also act improperly because of incorrectness of auditory signals. The proposed system enables the stable operation of the aircraft, regardless of the pilot's capability. Communicating DEVS (C-DEVS) is used to analyze and verify the behavior of the proposed system. A composed C-DEVS atomic model has overall composed discrete state sets of models, and the state sequence acquired through full state search is utilized to verify the safeness and the liveness of a system behavior. The C-DEVS model of the proposed system shows the same behavior with the traditional PAR control system.

  • 사용자 인터페이싱 환경을 위한 경제적인 입력 방법으로 핸드 인식기술이 널리 이용되고 있다. 그러나 대부분의 기법들은 고정된 배경과 정해진 패턴만을 인식하는 제한점을 가진다. 이러한 제한점은 수행환경의 제약과 다양한 응용분야에 적용하기 어렵다는 문제점을 가진다. 본 논문에서는 배경의 제약 없이 핸드 영역정보와 위치정보를 추출하여 입력 장치를 구동시키는 가상입력시스템을 제안한다. 본 연구는 개방 환경에서 사람의 입력을 요구하는 공항이나 전시관의 키오스크 시스템, 각종 조정장치 및 산업용 시스템분야에 경제적인 가상입력시스템으로 사용될 수 있을 것이다.

  • Hazardous volcanic activity will continue to occur in the ring of fire, a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. and, because of rising populations, development pressures, and expanding national and international air traffic over volcanic regions, risks to life and property through exposure to volcano hazards continue to increase. During an eruption, volcanic contamination can reach and exceed the cruising altitudes of turbine-powered aircraft, among others, within minutes and spread over vast geographical areas within a few days. Volcanic ash can affect the operation of aircraft at aerodromes. Volcanic ash deposition at an aerodrome, even in very small amounts, can result in the closure of the aerodrome until all the deposited ash has been removed. In this study, air traffic information framework is presented along with algorithms to define affected routes, waypoints and airports using GIS geometry analysis.
