| Summary: | 碩士 === 國立臺北科技大學 === 車輛工程系所 === 96 === Different subsystems of metro system constructions in the top cities of world have different lifecycle. For civil work formulation there is fixed number of life years over hundred year for architectures, but for electronic and mechanical systems that formulation are only limited less than thirty-five years. Therefore, those over hundred year’s revenue service metro system, the vehicle and train automatic control system have a high retrofit and upgrade exceeding. From the point of the view of system retrofit technologies, it is an important issue of research topic planning retrofit train automatic control system witout any interference in daily revenue service.
This thesis provides an analysis for renewing the conventional fixed block man less train operation system by a new generation of CBTC of moving block man less train operation system. The analysis is mainly based on author’s the experiences and participance of the retrofit Muzha Line of Taipei metro system. It is expected to find the solutions of existing and new interference problems of train control system, in order to make a clear picture of retrofit methods. The author expects this proposed solutions can be a useful reference of train control system retrofit for future processing in similar projects and events.
The technologies of train control systems for railway waysides and onboard equipments have changed and developed day by day, especially the knowledge radio system has widely adopted in train control system to replace the traditional track circle train control system. That traditional train control system will be eliminated graduately in the competition with the radio train control system. Generally speaking, there is a tendency to use these radio technologies in the train control system and Communication based Train Control (CBTC) system will be the main choice when the former system need to be retrofitted. Therefore, it is a top issue to make the new system installation and commissioning without any interference to the existing system revenue service during the sysem retrofit period.
