摘要
在引入移动闭塞概念的基础上,比较移动闭塞和准移动闭塞的技术差异,提出城市轨道交通列车安全间隔时间计算方法,推导出移动闭塞和准移动闭塞列车安全间隔时间计算公式,对两者进行仿真计算及分析。可知,列车以相同的速度运行,列车安全间隔越大,移动闭塞列车安全间隔时间比准移动闭塞列车安全间隔时间缩短得越多;列车安全间隔距离一定时,列车的运行速度越大,移动闭塞列车安全间隔时间和准移动闭塞列车安全间隔时间越接近。
On the basis of the introduction to the concept of the movable block, this paper compares the technology between movable block and quasi-movable block. It presents the algorithm for the safety time interval in urban mass transit and deduces the computation formulas for the safety time interval of movable block and quasi-movable block. Simulation calculation and analysis were carried out on both algorithms. It is known that when trains run at the same speed, the safety time intervals of trains with movable block system are reduced more and more than that of trains with quasi-movable block system as the safety intervals between two trains become longer and longer. When the safety intervals between two trains are invariable, the safety time interval of trains with movable block system are closer and closer to that of trains with quasi-movable block system as the speeds of trains are faster and faster.
