开放黄闪黄信号机主灯丝断丝误报警问题分析与处理

针对信号机主灯丝断丝报警报不出信号机具体位置的问题,通过微机监测的回放调看及试验,深入分析主灯丝断丝报警电路,发现在2架进站信号机同时开放黄闪黄灯光时会产生误报警现象。针对此电路存在的设计缺陷,提出了改进方案,并对类似问题提出了建设性意见。

Problem Analysis and Handling of Flashing Yellow Lights Main Filament Broken Wire Wrong Warning

As far as the problem that signal main filament broken alarm cannot report the specific posi- tion, this paper described the main filament broken wire circuit through playing back of microcomputer monitoring and testing, and it is found that such a false warning would occur when both two home signals are flashing yellow lights. As for the deficiencies in circuit design, this paper presents an improvement plan and put forward some constructive suggestions on similar problems.
