摘　　要：在《铁路自然灾害及异物侵限监测系统工程技术规范》Q/CR9152-2018中,针对异物侵限灾害监测系统,虽然给出了电网传感器长度的计算公式,但并没有给出异物侵限点对轨道区段影响长度范围的计算方法.因此在实际工程中,往往是根据经验值来判断异物监测点对轨道区段的影响范围,没有统一的标准和规范.本文结合相关规范文件,通过数学方法,创新性地提出了异物侵限点影响轨道区段长度的计算公式,进而确定需要串接异物侵限继电器的具体轨道区段,以有利于异物侵限防灾系统设计的标准化推广.In"Technical Code for Railway Natural Disaster and Foreign Object Intrusion Monitoring System"Q/CR 9152-2018,the calculation formula for the length of the grid sensor is given for the foreign object intrusion disaster monitoring system but the calculation method for the length of the track section affected by the foreign object intrusion point is not given.In actual projects,the project managers used to determine the length of the track section based on their experience data,which has no uniform standards and specifications.Therefore,a calculation formula for the length of the track section affected by a foreign object intrusion point is proposed using a mathematical approach according to relevant specifications and then the track sections needed to be connected in series with YWJ can be determined so as to standardize the popularization of the design of railway natural disaster and foreign object intrusion monitoring system.
