北京地铁新机场线长大区间信号设备控制距离解决方案的研究

摘要

Because of Beijing new airport metro line with a long section between stations, the control distance of trackside signals of the line is longer than that of conventional subway lines. This paper studies the requirements for the power supply, signal transmission, management and maintenance of the trackside signals in original design of the signal system, analyzes the solution of various kinds of signals involved in the system. It is proved that the solution is feasible by actual investigation and calculation, including the solution for management and maintenance of the signals on long sections.%北京地铁新机场线站间距离长，使得室外信号设备的控制距离很长，这与常规的地铁线路中正线的信号控制距离差别较大。从信号系统设计初期的角度研究在长大区间中如何保证信号设备在用电、信号传输以及信号设备的管理维护等方面的要求。对涉及到的各种轨旁信号设备应采取的解决方案进行分析与研究，通过实际调查与计算，确定方案的可行性。并对后期信号设备的管理维护提出解决方案。
