摘要
城市轨道交通电磁环境仿真工具基于电磁插值算法,通过对轨道交通系统中的若干电磁场强度数据点进行处理,并开发软硬件协同的仿真工具,精确预测平面内的电磁场强度分布。利用GNU Radio框架与USRP B210软件无线电平台,复现目标电磁环境,有效降低铁路沿线高昂的测试成本,实现了零现场的电磁环境分析。实验结果表明,城市轨道交通电磁环境仿真工具能够科学、合理地仿真城市轨道交通的电磁环境,确保系统的安全与高效运行。
An electromagnetic environment simulation tool for urban rail transit is developed based on an electromagnetic interpolation algorithm.By processing discrete electromagnetic field intensity data points within the rail transit system and implementing a hardware-software co-simulation tool,it accurately predicts the electromagnetic field intensity distribution across planar regions.Using the GNU Radio framework and USRP B210 software-defined radio platform,the tool reconstructs target electromagnetic environments,effectively reducing high testing costs along railway lines and achieving zero on-site electromagnetic environment analysis.Experimental results demonstrate that this urban rail transit electromagnetic environment simulation tool can scientifically and reasonably simulate electromagnetic environments,ensuring the system's safe and efficient operation.
