ETCS行车许可与临时限速功能的研究

Study on MA and TSR Function of ETCS

为了提高列控系统的控车安全性,以ETCS为研究平台,对行车许可(MA)最大长度的合理取值及其对临时限速(TSR)设置功能的影响进行了分析,提出2种限速设置时机控制方案,分别适用于ETCS-1级和ETCS-2级线路,可自动规避由限速设置引发运营线路上的列车意外制动风险,无需调度人员的人工干预。

In order to improve the safety of train control system, reasonable value of the maxi- mum length of movement authority and its effect on the function of TSR setting are analyzed. Moreover, two schemes for controlling the time of TSR setting respectively for ETCS-1 level and ETCS-2 level are proposed so as to automatically avoid the risk of unexpected train braking caused by imposing TSR on lines in operation without human intervention from the dispatchers.
