摘要
应答器作为高速铁路车地之间信息传输的关键设备,可以实现列车位置校准及信息传输。其在铁路沿线上布置的数量、间距以及发送数据的冗余度都会对列车运行及列控系统产生影响,对这些影响参数进行研究,可为优化应答器的布置、提高行车效率提供依据,也可以指导工程建设,以较少的投资获取较高的效益。本文采用DEA与AHP相结合的评价方法,在应答器布置方案较少的情况下,兼顾评价的客观性,同时获得量化的排序结果。对于不能直接从方案中转换为数据的指标,采用计算机仿真作为辅助手段,从仿真中获取定量的统计数据,使用DEA与AHP方法综合分析数据,对不同的应答器布置方案给出量化的评价排序。
As the key equipment in information transmission between cab and ground, the balise can be used in train position calibration and information transmission for high-speed railways. The number of balises laid along a railway line, the space between two balise sets and the redundancy of transmitted data affect the train running and train control systems. Study of these influential parameters may serve to provide a basis for optimizing the balise layout and improving traffic efficiency and to guide engineering construction to achieve more benefits with less investments. In this paper,the DEA and AHP integrated evaluation method was adopted to accomplish ob- jective evaluation and quantitative sequencing in the case of less balise layout schemes. For those indexes which can not be directly converted from balise layout schemes to data, quantitative statistical data were acquired throuth computer simulation. All data were analyzed comprehensively with the method of DEA and AHP,and the quantitative evaluation sequence of different balise layout schemes was obtained.
