摘　　要：在城市轨道交通列车自动控制系统 ( ATC)中 ,列车自动防护 ( ATP)系统担负着列车运行间隔控制、进路控制、超速防护的重要作用 ,是列车运行自动控制的基础。其中 ,ATP车载设备是 ATP系统中保证行车安全的关键设备 ,它根据地面信息和机车信息生成列车速度控制曲线 ,并与列车实际速度进行比较 ,监督列车运行 ,实现超速防护、零速检测、无意识移动防护、制动确认和车门防护等功能。本文在介绍 ATP系统仿真的基础上 ,重点阐述了 ATP车载设备列车速度控制模式曲线的仿真计算方法 ,并以北京地铁一号线的线路参数为例 ,对 ATP车载设备的速度控制模式曲线进行了仿真 ,实现了车载 ATP的超速防护功能。目前 ,整个 ATP仿真系统已正式投入运行 。Serving as the basis of Automatic Train Control (ATC) system of Urban Mass Transit, Automatic Train Protection (ATP) system plays an important role in interval control, route control and overspeed protection. The onboard ATP, however, is the key component of ATP system to insure the train safety. It calculates the train speed control curve based on the railway information stored in the host computer and the data received from wayside. It constantly compares the velocity calculated with the train actual velocity to supervise the train operation. It executes overspeed protection, zero speed check, unexpected movement protection, brake confirmation and door protection. The paper introduces the simulation of ATP system and describes the method of calculating speed control curve in details. It simulates the speed control curve with the simulation of the overspeed protection mode with parameters of No 1 loop route of Beijing subway. The whole simulation system is in service and has acquired good effects as expected.
