典型交叉区域GSM-R无线覆盖方案设计

对交叉区域按两线交叉相对位置关系、线路的列控等级、基站设置位置与交叉点位置关系、有无联络线等因素进行了详细分类,并针对每种类型给出了具体的无线覆盖方案建议;然后选取了郑徐客专与京九线交越区域和商合杭铁路引入芜湖站二个典型案例,将交叉区域无线覆盖方案设计建议进行了示范应用;最后总结了交越区域GSM-R系统的设计原则,其他铁路交叉区域的GSM-R系统方案设计可直接参考。

Design of Wireless Coverage Solution of Typical GSM-R's Cross Zones

This paper elaborately classified the cross zones according to the relationship of relative location of two crossing lines,levels of train control over the lines,the relationship between the setting location of the base station and the location of the cross point,and whether there is a con­necting line as well as other factors.Besides,specific proposals for wireless coverage solution to each class of the cross zones are given.Next,using two typical cases of cross zones,one cross zone between Zhengzhou-Xuzhou PDL and Beijing-Jiulong railway and the other connecting Shan-gqiu Hefei railway into Wuhu Station,the design of the wireless coverage solution to cross zone is demonstrated.Finally,the design principle of GSM-R system for the cross zone was summa rized.offering direct reference for designing the GSM-R system of cross zones in other railways.
