高速铁路道岔表示电压安全采集方案研究

摘要

针对高铁道岔表示电压采集存在的问题，分析了其存在的原因，提出了采集的新方案，特别研究了安全隔离的措施和手段，大幅提高道岔表示采集的安全性。%As for some problems existing in collecting switch indication voltage of speed-up switch used in high-speed railway, we analyzed the causes of those problems, put forward a new solution of voltage collect and especially made research on security isolation methods, greatly enhancing the security level of switch indication collection.
