摘要
针对高铁选线的不合理性和不科学性,提出基于WDM-PON(波分复用型无源光网络)技术的高铁选线信息共享系统设计。通过WDM-PON技术与层次分析法相结合,整合影响铁路选线的因素,构建多层次分析模型,结合集对分析法共同计算所选线路的联系度,并按照三级优劣等级划分,联系度最大即代表级别最高、所选的线路最优,完成高速铁路的选线信息共享系统设计。实验结果表明,所提方法确定了ND1线路的优劣等级为一级,明确了ND1线路为最优线路,并且其选线耗时在1.0 s以下,远低于其他方法,同时其准确率达到了98%,因此,该方法有效找出了最优线路,提高了选线的准确率,降低了系统运行耗时,为选线提供了科学的参考依据和坚实的理论基础。
In view of the irrationality and unscientificity of high-speed railway line selection,an information sharing system for high-speed railway line selection based on WDM-PON(Passive Optical Network of Wavelength Division Multiplexing)technology is proposed.Through the WDM-PON technology combined with analytic hierarchy process,integrated the factors influencing railway line selection,building multilevel analysis model,combining with the set pair analysis method to calculate line connection degree,and in accordance with the class or division,its maximum contact degree that represents the highest level,the selected lines optimal,complete information sharing system of the high-speed railway.Experiments results show that the proposed method to determine the ND1 line quality grade evaluation for level 1,has been clear about the ND1 circuit for the optimal circuit,and the concept of time-consuming in 1.0s,far lower than other methods,and its accuracy reached 98%,therefore,this method is effective to find the optimal lines,improves the accuracy of line selection,reduces the system running time consuming,it provides scientific reference and solid theoretical basis for line selection.
