摘要
铁路沿线电磁环境日趋复杂,避免出现覆盖弱场区或通信中断是高铁移动通信网络规划的首要任务和基本要求。为保证GSM-R系统安全可靠运作,提出一种基于高性能射线跟踪的GSM-R高精度网络覆盖优化技术,结合BIM和GIS技术的GSM-R高精度网络优化方案,以高性能射线跟踪仿真技术代替测试车辆及人工调试,实现"精准高效,一键完成"的GSM-R网络覆盖优化。并以京雄高铁的无线网络场强覆盖仿真结果为实例,阐述该方法的合理性与可行性。
The complexity of electromagnetic environment along railways is increasing.Avoidance of weak field coverage or communication interruption is the primary task and requirements for high speed railway mobile communication network planning.A GSM-R high-accuracy network coverage and optimization technology based on high-performance ray is proposed to ensure that the GSM-R system is under safe and reliable operation.The GSM-R high-accuracy network optimization scheme in combination with BIM and GIS technology is proposed.Through the scheme,high-performance ray-tracing and simulation technology replaces the test vehicle and manual commissioning,which improves GSM-R network coverage"in accurate,efficient and one-key completion manner".The rationality and feasibility of the method is illustrated by taking the simulating results of wireless network field coverage of Beijing-Xiong’an High Speed Railway as an example.
