数字轨道电路列车最小安全间隔时间计算

Calculation of Time Interval between Two Trains in Moving - block Signal System

采用数字轨道电路作为车一地信息传输设各及列车定位设备时，列车之间的安全间隔距离必须以数字轨道电路的长度作为最小计量单位。本文在推导出列车安全间隔时间计算公式的基础上，提出了基于最小列车安全间隔时间的数字轨道电路长度的推荐值。

When digit signal orbital circuit is adopted in the equipment, which is used to transmit train-to- wayside information and location train position, the length of digital signal orbital circuit should be the minimal mea- sure unit of distance interval between trains. On the basis of time interval calculate formula which has been deduced, this paper offers the recommended length of digital signal orbital circuit in the condition of the minimal of the time interval.
