铁道部1984年颁布的“区间铁路道口自动信号”定型制式和施工组装电路图,使一般区间道口设置自动信号问题得以解决,但对靠近车站道口的自动信号却无图可借鉴。文章介绍了柳州铁路局柳州工务段道口信号QC小组,以上述问题作为攻关课题,通过原因分析,采取相应对策,并组织了实施,最后取得了较好效果。 Ministry of Railways in 1984 promulgated the “section of the railway crossing automatic signal” stereotypes and construction of assembly circuit diagram, so that the general interval crossing automatic signaling problem can be solved, but the automatic signal near the station level crossing without drawing. This article introduces QC team of crossing signal of Liuzhou section of Liuzhou Railway Administration. Taking the above problems as the research topic, through the analysis of the reasons, we take the corresponding countermeasures and organize the implementation. At last, we get the better result.
