摘　　要：对于非列控区段的普速铁路,由于线路等级不高,通常没有配套建设GSM-R无线信号监测设备,也无法直接照搬高速铁路的网络优化及监测系统。为此提出一种简约化的GSM-R网络优化方法和系统解决方案。利用前端感知终端开展线路侧无线信号采集并进行自动化测试,通过公、专融合的网络形式实现路测数据的一键回传;利用后端服务平台建立智能分析系统模型,实现数据的智能融合分析,初步判断并识别铁路沿线无线信号覆盖薄弱区域、GSM-R服务小区异常等情况,自动生成测试报告和网络优化解决方案,并将相关信息传递给线路侧维护人员,以便其及时、精准地进行现场网络优化工作。采用这种智能化、简约化的网络优化方法,符合提质增效、一体化综合维修的建设思路。For the section without train control system of conventional speed railway line,there is usually no supporting wireless signal monitoring equipment because of its low operation grade,and it is impractical of applying the network optimization and monitoring system of high-speed railway directly.To this end,a simplified network optimization method and system solution are proposed.The front-end sensing terminal is applied to collect wireless signals on the line side and carry out automatic testing,and the“one-click”sending back drive test data are realized through the integration of public and private networks.The intelligent analysis system model is established by using the back-end service platform,which realizes the intelligent data fusion analysis,preliminarily judges and identifies the areas with weak wireless signal coverage along the line and abnormal GSM-R service area,automatically generates test reports and network optimization solutions,and transmits the information to the line-side maintenance personnel,so as to timely and accurately optimize the field network.This intelligent and simple network optimization method is in line with the construction idea of improving quality and efficiency and integrating maintenance.
