中文摘要 | 本局從文湖線開始,行車監控系統就採用CBTC(Communication-based Train Control, 通訊式列車控制)技術, CBTC技術的主要特點是列車自動控制系統的控制及監測訊號, 經由無線通信的方式以及軌旁信標設備的偵測,並經快速的數據傳輸及計算,來提供移 動閉塞區間的功能,以縮短列車間距,提高系統運能,減少軌旁電纜鋪設及後續的維護 成本。 由於環狀線行車監控系統也將採用CBTC式的無人駕駛系統,而此CBTC系統需高度 依賴列車、軌旁及行控中心間的高速通信傳輸,因此必須有一套有別於傳統軌道電路的 高可靠度光纖傳輸系統-資料傳輸系統(DCS,Data Communications System)。為確保能提 供一套符合行車監控需求的高可靠DCS光纖骨幹系統,除於設計階段須考量光纖設備選 用、備援設計考量及故障收斂時間等設計因素外,營運前尚需執行嚴格的現場測試。 |
英文摘要 | Communication-based Train Control (CBTC), an automatic train control system, was first adopted on the Taipei MRT Wenhu line. CBTC technology uses radio communications to transmit control and monitor signals. In addition, CBTC provides moving block functionality so that system capacity can be enhanced and the cost of the trackside cable installation and maintenance can be reduced. Using a beacon transmission mechanism and speedy data communications and calculations, the CBTC system is able to locate the position of trains precisely, thus allowing headway to be improved. The driverless CBTC system that is to be adopted in the operation control system of the Circular line depends on high speed communications between trains, the Operation Control Center (OCC), and trackside. When compared with the data transmission backbone used in traditional track circuit signal systems, the Data Communications System (DCS) adopted by the CBTC system must be a highly reliable optical transmission system with a different configuration. The optical equipment selection, redundancy design considerations and system failure time convergence shall be considered as basic DCS design elements. After the above design elements have been carefully evaluated, complete onsite testing of the DCS will be conducted to ensure that the DCS is not only a highly reliable optical transmission backbone but it can also fulfill the demands of the operation control system. |
