摘要
安全治理是“十四五”期间提升铁路服务水平的主要任务及研究领域之一。旅客安全管控及安防监控系统的设计是实现该目标的有效途径,并体现在视频设备的径路布设点优化。现有的设计方、施工方及设备集成商均未对此进行深入研究。针对高铁站房视频监控设计缺乏仿真优化的问题,提出将监控设备覆盖范围转换为公差式和点位径路,并分析了两者关联性。该方法对铁路站厅的视频监控径路分组,根据均方根法公差计算验证,并基于偏微分方程建立径路数学模型,在此基础上进一步优化计算过程;最后结合实际的参数和互换性要求,确定最终的径路并加以仿真运行验证,提高了该设计方法的操作性和准确性。
Safety governance is one of the main tasks and research areas to improve the level of railway services during the′Fourteenth Five-Year Plan′period.The design of passenger safety control and security monitoring systems is an effective way to achieve this goal,and reflected in the optimization of designs of video equipment.The existing designer,construction party,and equipment providers have not conducted in-depth research on this.In response to the lack of simulation optimization of video surveillance design of high-speed railway stations,it was proposed that the surveillance equipment coverage area was converted into a tolerance type and point pathway,and the correlation between the two was analyzed.This method was paid for the video surveillance node data preprocessing of the railway station hall,calculated and verified according to the average square root method,and established mathematical models based on the differential division equations.Based on this,the calculation process was further optimized;finally,the final path was determined in combination with the actual parameters and interchangeability requirements and verified by simulation operations,which improved the functionality and accuracy of the design method.
