摘要
分析和研究了地铁列车ATC系统的常见故障,论述了对其故障频率进行科学预测的重要性,利用Stata对上海地铁故障日志进行了筛选分类及数据整理,并用泊松回归模型对ATC系统故障频率科学预测,以确保地铁安全运营。
The paper analyzes and researches the common failures at the subway train ATC system,indicates the importance of the scientific prediction of its failure frequency,adopts Stata to undertake the sifting sort and data compilation of the failure records of Shanghai Subway,and has the scientific prediction of the failure frequency of ATC system by adopting Possion distribution model,so as to ensure the safety of subways.
