Abstract

The PRT(Personal Rapid Transit) in material or immaterial guided tracks is operated automatically according to the needs of passengers with the optimal non-stop path from the source to the destination. In recent years, the personal rapid transit (PRT) system, which affords superior accessibility and ease of use, has been spotlighted as a new transport system for the future. In this study, a method for vertical lifting of PRT vehicles was proposed to facilitate interlink with other means of transport and thereby improve the efficiency of door-to-door transport. For this purpose, operation control interfaces were designed and experiments were conducted. Programmable Logic Controller (PLC) dedicated for the PRT vertical lift was designed to interface with Operation Control Center (OCC) by Modbus TCP over Ethernet. We implemented a 3D graphical PRT operation simulator which can emulate the mixing operation of the virtual vehicles and the actual vehicles.

PRT(Personal Rapid Transit)는 유형 또는 무형의 전용궤도에서 자동으로 승객의 요구에 따라 출발지에서 목적지까지 최적의 경로로 논스톱 운행하며, 높은 접근성과 프라이버시 보장 등 자가용 수준의 서비스 제공이 가능한 대중교통수단으로서, 최근 새로운 미래교통시스템으로 재조명받고 있다. 본 논문에서는 PRT 시스템의 연계 운행 효율성 극대화를 목표로 수직이송장치를 연동제어하는 PRT 운행제어시스템의 제어모듈 및 시뮬레이터의 설계 및 시험결과를 제시하였다. 수직이송장치부의 PLC는 운영제어센터 또는 역제어시스템과의 인터페이스를 위해 Modbus 프로토콜을 적용하여 설계되었으며, 원격제어시스템으로부터 명령을 전달받아 동작하는 자동모드와 수직이송장치에 설치된 센서검지 상태에 따라 독립적으로 동작하는 수동모드로 구성하였다. 또한, 실제 차량이 운행하는 환경에서 가상의 차량운행 시나리오를 적용하여 실제 차량과 가상 차량을 혼합하여 운행할 수 있는 3D 그래픽 기반 PRT 운영제어 시뮬레이터를 구현하였다.
