一个基于轨道电路的自动闭塞的离线模拟器

An Off-Line Simulator for Track Circuit Based Automatic Blocks

为了研究智能列车调度与控制的理论与实现技术，需要首先建立相应的 铁道线路、机车、车辆和信号系统的仿真模型和系统。列车自动控制系统分为地面和车 载两个子系统，它具有闭环控制的特性。而地面控制子系统又可分为自动闭塞和车站联 锁两个部分。本文阐述了一个基于轨道电路的自动闭塞的离线模拟器的主要功能、仿真 的原理和结构，并提出了一种减小仿真自动闭塞设备延迟误差的方法。该软件模块己在 Ｗｉｎｄｏｗｓ ９５和 Ｍｉｃｒｏｓｏｆｔ ＶｉｓｕａｌＣ＋＋ ４． ２环境下实现，并能与列车静态和动态特性 仿真模块和列车运行自动控制策略仿真模块配合使用。

Computer simulation has found many applications in the development of transportation automation systems. An automatic train control (ATC) system consists of a vehicle ATC subsystem, an automatic block subsystem, and an interlocking subsystem. In this paper,the main functions of an off--line simulator for track circuits based automatic blocks are introduced. The principle and structure= of the simulator are presented,and an approach to decrease the delay error of the simulation of automatic block equipment is proposed. This simulator is implemented by Microsoft Visual C++ 4.2 for Windows 95.
