Research on High-Speed Railway Block Signal Layout System

高速铁路区间信号机的设计原则是保障列车运行安全、提高线路通过能力与节省工程建设成本。本文首先根据列车运行仿真原理提出区间信号布点方案的线路通过能力与行车安全检算方法，而后分析信号布点方案的建设成本影响因素，提出以轨道电路极限长度递推布置信号点的方法，并开发高速铁路区间信号机布点系统，最后以实际线路为例进行验证。结果表明：本系统信号布点方案可减少信号机和轨道电路分割点的数量，有助于降低建设成本。
The design principle of high-speed railway block signal layout is to ensure train operation safety, improve line passing capacity and save construction cost. Firstly, according to the principle of train operation simulation, this paper puts forward the checking calculation method of line passing capacity and traffic safety of block signal layout scheme, then analyzes the influencing factors of construction cost of block signal layout scheme, puts forward the method of recursive layout of block signal based on the limit length of track circuit, and develops the block signal layout system of high-speed railway. Finally, it is verified by taking the actual line as an example. The results show that the signal layout scheme generated by the developed system can reduce block signal and track circuit division points, which is contributing to save the construction cost.
