摘　　要：临时限速命令在TDCS/CTC系统中至关重要,通常情况下调度台所涉及的临时限速公里标范围包含1个或2个里程标系,而在跨越3个或多个里程标系时临时限速命令的处理变得复杂,需要转换限速命令里程标系并计算覆盖标志。以TDCS-y系统为例,分析了多里程标系情况下临时限速命令覆盖标志的计算问题。Temporary speed restriction is a vital part of the TDCS/CTC system.In most cases,kilometer posts are positioned with one or two mileage origins.The range of kilometer posts,however,could contain three or more mileage origins,resulting in a growing complexity in the programming process of TSR.This paper analyzes the calculation problem of TSR command override flag with multiple mileage origins taking the TDCS-y system as example.
