(t )具有筛选f (t )在t 0处函数值的性质 (t t0 )具有筛选f (t )在t t0处函数值的性质
(t ) ( t )
奇偶性
•由定义2，矩形脉冲本身是偶函数，故极限 也是偶函数。
•由抽样性证明奇偶性。

系统概述
CC内部存有轨道数据。该数据包括全线线路的土建、道岔位置、信标位 置等信息。列车运行时，CC根据速度传感器检测的速度信号计算出列车的走 行里程，并在轨道数据库中反应出列车理论位置。由于速度传感器检测误差、 计算时对循环小数的取舍、轮径磨耗等原因，理论位置与实际位置存在一定 的误差。这个误差会一直积累。 静态信标：无源信标，用于修正列车上述误差。静态信标安装在线路上， 作为绝对位置。CC根据读取静态信标来修正轨道数据库中的列车理论位置， 使理论位置更趋近于实际位置。区间内的静态信标大约每200米设置一个， 站台区域由于ATO需准确停车，所以需增加静态信标的的数量。 动态信标：有源信标，用于向CC传送信号机的状态信。CC根据动态信 标的信息获知前方信号机的状态（绿灯、黄灯或红灯）。 计轴：安装在钢轨的侧面。计轴用来检测轨道区段的占用和出清。计轴 器分为发送端和接收端，发送端可以看作一个磁体，它的周围分布着磁感线。 当列车的一个轮对压过计轴器时，车轮就切割一次磁感线，计轴器就检测到 该列车占用下一轨道区段。当上一个计轴器记录该轨道区段的轴数等于下一 个计轴器记录出该轨道区段的轴数，系统就认为该轨道区段已出清。
一、系统概述
• 2、贯穿在信号系统设计中的基本原则是： 安全、可靠，最大限度地实现功能，最大 限度地减少系统故障的发生。正线信号系 统提供了降级或紧急运营模式。在CBTC系 统出现故障时，所有在正线范围内作业的 列车仍可被系统探测及追踪；并在正线线 路适当位置设置轨旁信号机协助司机驾驶， 以维持列车服务。同时也可让没有安装车 载信号设备的列车在正线安全作业。
