ZPW-2000R轨道电路方向切换对小轨道状态的影响分析

Analysis of Influence of ZPW-2000R Track Circuit Direction Switching on the Status of Small Track

目前区间轨道电路普遍将小轨道状态纳入列控中心检查范围。轨道电路在方向切换过程中,受小轨道状态检查结果的影响,可能导致整个轨道区段闪红光带。以ZPW-2000R轨道电路为研究对象,从小轨道状态检查原理和机制入手,深入分析方向切换过程中可能出现的不同场景对小轨道状态检查结果的影响,并给出结论与建议。

At present,small track is generally included in the technical scheme of train control center inspection for section track circuit.Due to the influence of small track status inspection results during the direction switching of track circuit,the flashing red light strip may occur in the whole track section.Taking ZPW-2000R track circuit as the research object,starting with its small track status check principle and mechanism,this paper deeply analyzes the impact of different scenarios that may occur during direction switching on the small track status check results,and gives conclusions and suggestions.
