  • In this paper, the inductive power collector using electromagnetic induction for the PRT(Personal Rapid Transit) system is suggested and some ideas for power collector design to improve the power transfer performance are presented. The proposed the inductive power collector is used for the PRT system, which has a large air-gap and demands a large electrical power capability. But, low output power is generated due to a loosely coupled characteristic of the large air-gap. Therefore, double layer construction of secondary winding. which was divided in half to increase both output current and output voltage was suggested. Also, model of power collector and parallel winding structure are presented, in addition, the performance of inductive power collector to alignment condition between the primary power line and the inductive power transformer was verified by computer simulation of 2kW model.

  • 차량 자동주행제어시스템에서 차량의 주행중 위치정보는 매우 중요한 요소이다. 이를 위해 GPS를 기반으로 하는 많은 연구가 수행되어 왔다. 하지만PRT(Personal rapid transit) 시스템과 같이 건물내부 또는 터널 등 위성의 가시권을 벗어난 영역에서는 사용성이 크게 제한된다. 본 논문에서는 이런 적용환경을 고려하여 국내에서 개발되고 있는 PRT차량의 주행제어 시스템에서 활용하기 위한 자석검지시스템과 자석검지기술을 제시하였다.

  • In this paper, the inductive power collector using electromagnetic Induction for vehicle such as the PRT(Personal Rapid Transit) system is suggested and some ideas for power collector design to improve the power transfer performance are presented. The inductive power of secondary part is related to amount of linked flux to secondary part by the length of air-gap, which is expected by such a system parameter as mutual inductance. This paper will study for the transfer characteristic of power from input to output and equation including mutual inductance.

  • The PRT can be divided into In-Track and On-Board according to propulsion method. In process of In-Track, vehicles driven by LIMs(Linear Induction Motor) which are installed in Guideway. Central Controller, which control whole machine, must control speed and direction of all vehicles. In this case, as vehicle increases, Central Controller will overload. If Central Controller fails, all vehicle stops. To avoid this problem, processing of Central Controller must be distributed. This paper introduces method of Distributed Routing. Method of Distributed Routing will provide safety and efficiency for PRT System.

  • This study is concerned with the design of the communication based evaluation simulator for the development of the operational control algorithm for PRT(Personal Rapid Transit) system which has very short headway and requires accurate speed control of the vehicles to avoid the impact between the vehicles. The evaluation simulator is composed of central control system, vehicle control system, communication control system, AP for wireless communication, and monitoring system. For the mobile characteristics of the PRT vehicles wireless communication is employed for the transmission of the control and status information between the central control system and the vehicle control system. By using simple test operational control algorithm the effectiveness of the proposed evaluation simulator is shown.
