摘 要: 中低速磁悬浮作为一种新兴的交通工具,以其相对传统轨道交通的优势,发展前景广阔。本文基于设计时速100 km/h,运行间隔3分钟的中低速磁浮工程模型,信号系统采用“点连式ATP系统”。首先对中低速磁浮“点连式ATP系统”展开分析,研究本系统与传统轮轨系统及高速磁浮系统的差异,提出本系统的关键性技术是列车测速测距、列车定位、轨道占用检查及无线通信覆盖。前三项关键技术主要解决与传统轮轨系统的差异问题,无线通信覆盖方案解决与传统点式ATP系统的差异问题,从而给出一套完整的适合中低速磁悬浮的信号系统解决方案。

Abstract:The newly rising means of transportation, intermediate-low-speed maglev train, has a quite broad prospect comparing to the traditional ones. Based on analysis of the point-continuous signaling system model with a 100 km/h design speed and 3-minute tracking interval, this paper firstly studies the point-continuous ATP system, offering a glimpse of the difference between this system and the traditional wheeltrack and the high-speed maglev trains. The conclusion is that the key technologies are the distance and speed measurement, train locating, track occupation detecting and wireless communication covering. The former three technologies are mainly the difference between this system and the traditional wheeltrack ones, leaving the difference between the ATP and the traditional ones to the wireless communication covering technology, and concludes with a possible technical solution for the signaling system of intermediate-low-speed maglev railway.
