서울메트로에서는 설치된 총 399개소의 신축이음매장치의 레일변위(stroke)와 장대레일의 온도를 정기적(월2회) 및 부정기적으로 점검 하고 있다. 특히, 혹서기에는 레일장출 방지를 위해 수시로 레일온도 및 신축량을 점검하고 있다. 이에 따른 업무효율 저하와 직원들의 선로현장 출입에 따른 인명사고 위험이 상존하고 있어 사무실에서 실시간으로 레일온도 및 신축량을 통합관리하는 시스템의 필요성이 대두되고 있다. 본 연구에서는 대기온도, 장대레일의 레일온도 및 신축이음매장치에 대한 레일 변위 등을 자동으로 측정하는 장치를 개발하였다. 현장 센서에서 취득된 데이터를 전용 통신케이블을 거쳐 관리자용 컴퓨터 시스템에 저장되어 모니터링 할 수 있도록 하였다. In Seoul Metro, the temperature of the continuous welded rail and the displacement (stroke) of the rail expansion joints installed a total of 399 places is checked regularly (twice a month) and irregularly. Especially in hot summer, there is often check rail temperature and expansion length to prevent bucking of rail. In accordance with decrease in working efficiency and the risk of accidents on the track, there is a need for a integrated system which manage rail temperature and displacement in real-time in the office. In this study, the atmospheric temperature, the rail temperature and displacement of the rail expansion joints had developed a device that automatically measures. Data obtained in the site sensors was stored in the administrative computer system and able to make monitor.

The object of this study is to propose a rate of vibration increase in the analysis of temporary rail non-fixed in the vertical direction and characterize the nonlinear dynamic behavior of temporary rail while considering longitudinal and latitudinal load, vibration and lifting. The rate of vibration increase is proposed through measurement of an actual structure that is largely affected by loading and vibration of the superstructure. Dynamic behavior was additionally characterized by the dynamic response resulting from nonlinear dynamic finite element analysis with vehicle loading, including the rate of vibration increase. As a result, the rate of vibration increase by the vibration of an Auto Bar Machine is determined as 7% and the maximum stress in the analysis of the nonlinear rail is increased 14.5% over that of linear rail, and temporary rail is shown to be very sensitive to the velocity of the superstructure. 본 연구는 일반적인 궤도 구조물괴는 달리 지지부와 받침이 레일과 상하로 구속되어 있지 않은 가시설 레일을 해석함에 있어 상부 하중에 의해 발생하는 종 방향 하중과 횡 방향 하중 및 진동, 그리고 들림 현상 등을 고려하여 가시설 레일 구조물의 하중 증가율을 제안한 후 비선형 동적 거동 특성을 파악하는데 목적이 있다. 그리하여 상부 구조물의 하중과 진동에 의한 영향이 클 것으로 판단되는 철근 배근 장치에 대한 실구조물 계측을 통해 하중 증가율을 제안하였으며 비선형 동적 유한 요소 해석을 실시하여 진동에 의한 하중 증가율을 고려한 차륜하중에 의해 발생하는 동적응답을 통해 동적 거동특성을 파악하였다. 그 결과 철근 배근 장치의 진동에 의한 하중 증가율을 7%로 제안하였으며 비선형 동적 거동은 선형화된 레일에 비해 최대응력이 14.5% 증가하였고 상부 주행 장치의 속도에 민감하게 반응하는 것으로 나타났다.

운반설비 중 보편적 기술의 하나인 EMS (Electric Monorail System)는 천장 트러스에 매달려 운반물을 이송하는 장치로, 공간 활용의 극대화라는 장점과 더불어 저소음 등 작업 환경이 개선된다는 점에서 널리 이용되고 있다. 본 논문에서는 운반물의 하중을 지지하고 고속 이송시 가이드 역할을 하여 이탈을 방지하는 EMS 레일에 대하여 다양한 방법으로 해석하고, 이를 바탕으로 레일 단면 설계의 최적화 방향을 모색한다. 경량이면서 고강성을 지닌 레일은 트러스에 가해지는 하중을 최소화 하고 이로 인한 레일 생산비 절감 및 설치 작업성 향상 등을 기대할 수 있다. Among the material handling system, EMS (Electric Monorail System), which is the facility of transferring the material hanging on truss, has the strength point of the maximum utilization of working space and the improvement of working environment including low-level noise generation. This paper will introduce the variable method of EMS rail analysis, which has the main role of supporting the whole material weight and guiding them with high-speed transportation, and, based on the analysis, the direction of optimization of the rail design be described. The rail with light-weight and high-strength contributes the reduction of the load of truss, the cost-down of rail production and the easy-installation on site.

In case of many products placed on the production line in automobile production, some line is personnel visually identifiable, such as CCTV, while the rest areas are not identifiable. However, because the position of accidents is not scheduled and every accidents should be analyzed at every point, every accidents is not easy because you need to an immediate response. The record cause of the accident is difficult to understand, not until after the accident for the accident cause analysis of fragmentary and mechanical information so that future accidents have difficulty measures be established. To prevent this, the car accident occurred in the manufacturing plant personnel to deploy and monitor in every area of enterprise is too burdensome labor costs too high. In this study, automated car production plant and load transfer system crash, accident collision and records are available for real-time wireless transmission, the administrator determines that situation can be immediately developed the electronic mono rail system(EMS). You will start to develop the control of EMS and stop control is critical for the correct parts first perform CAE analysis to develop a prototype.

This study proposes automation measures of anti-collision detection within EMS(Electrical Mono Rail System). EMS is a full automation transport equipment mainly used in production process, such as car manufacturing planets, electronic factories and food processing plants among manufactures. This research paper presents a plan for creating a smart EMS and overcoming an weakness of EMS. The mechanical strength and durability are ensured in the expected major collision region by performing a CAE analysis. Automated equipment has to respond to a sudden accident which is based on the self-image recording function and wireless transmission function. This equipment will record a sudden crash course in real time and record it. This record eventually becomes known to distant places with users. Because of this equipment, the unexpected accident is prevented and is reduced a human damage and is expected to improve productivity. Therefore, this research results are as follows. The first, the full automated conveyor controller is developed within from 3 to 4 millimeter stop range according to increase of load weight in 1.5 tons. The second, wireless image recording system for the measures of unexpected accident is developed through the CAE analysis of main parts for the exact stop control. The most important final purpose of this research is developed the wireless image recording system for the unexpected accident.
