摘要
异物侵限灾害的影响范围由防灾设计单位确定,并向信号设计单位提供具体资料。从防灾专业的角度,异物侵限监测范围越大越好,但从信号专业的角度,监测范围设置过大可能会导致设计的异物侵限灾害影响范围大于实际的影响范围,从而影响行车效率甚至危及行车安全。文章分析公跨铁立交桥异物侵限监测范围对列车运行控制系统(简称:列控系统)处理的影响,通过公式计算给出二者关系,并分别从防灾和信号角度提出了合理的建议。
The scope of the impact of foreign objects invasion is determined by disaster prevention design department,which provides exact data to signal designed department.From the point of view of disaster prevention,the greater therange of the foreign object invasion monitoring,the better it is.However,from the point of view of signal speciality,the excessive range of monitoring may lead to a larger designed impact area compare with the fact,thus wouldinfluence traffic efficiency and even endanger traffic safety.This article analyzed the impact of range of foreign objectinvasion monitoring on processing of train control system in highway overpass railway,put forward the correlationbetween them through formula calculation,proposed several reasonable suggestions from the angle of disasterprevention and signal.
