본 논문은 최근의 정보통신기술을 적용하여 아날로그 감지기와 화재경보시스템의 설계와 구현방법에 대한 사례를 기술하였다. 근거리와 원거리뿐만 아니라 중대형 규모의 건물에 설치할 수 있도록 감지기에서 부터 시스템까지 계층구조로 설계하였고, 대량의 이벤트를 효율적으로 처리하여 많은 정보를 보여주도록 통신프로토콜부터 응용프로그램까지 일관되게 설계하였다. PC 기반의 화재경보시스템은 Microprocessor 기반의 해외 제품보다 고속으로 대용량을 처리하고 큰 화면에 많은 정보를 제공한다. 그러므로 수천 개의 아날로그 감지기를 설치하는 대형건물도 하나의 시스템에 쉽게 수용할 수 있고 다중화장치를 이용하여 설치비용도 크게 절약할 수 있다. 본 시스템에서 구현된 경보시나리오는 경보가 발생할 때 비화재와 실화재를 구분하는데 큰 역할을 할 것으로 판단된다.

The conning display which is located in the ship bridge shows the various important information such as ship position, ship speed, track data, rate of turn, thruster rpm so on, and is one of the IBSs(Integrated Bridge Systems). In this study, the survey was conducted for ten officers to find the importance and using frequency of the information which were displayed in the conning display. The results showed that the information of drift speed, ship speed, wind direction and wind force, rate of turn, sea water depth, ship position, heading, thrust rpm, alarm, rudder command and angle got high scores and it meant that these information were very important and high frequency of use during the navigation. The optimized contents arrangement in conning display was suggested based on importance and using frequency of information. The experiment using eye-tracking system was conducted to compare the performance time and error rate of nine different scenarios for suggested arrangement display and three other existing displays. The results showed that the suggested arrangement was the best in performance time and error rate. The scenario concerning the direction and speed of wind showed faster performance time and lower error rate than other scenarios. The movement of subject's eye tended to search from the center and to avoid the comer, called 'the comer effect.' It is expected that the results of this study could help for the bridge staff to grasp the sailing information easily and to cope with the given situations promptly.
