摘要：随着科技的进步无线通信技术得到了广泛地使用，同时无线通讯技术也在飞快地发展。对于现代列车的控制也离不开无线通信技术的支持。列车自动监控系统（ATS系统）是用来实现对列车的监视与控制系统。通过ATS的人机界面系统调度员可以通过其中的场站图（场站图是ATS最主要的界面）对列车实行监控，并且ATS的场站图可以实时反应列车的行驶方向，驾驶模式，精确位置及运行设备的运行状态保证行车的安全。

随着目前越来越快得城市轨道交通的发展，列车行驶的安全性也更多地被人们所考虑。就上海而言也已经出现过多种事故，令大家影响最深刻的就是2011年9.27地铁10号线的追尾事故。虽然主要原因是由于调度员的失误所致，但这也足以证明ATS系统在整个列车运行系统中的中的重要性。如果能够进一步完善现有的ATS系统那对铁路行业来说是一个重大的福音，如何能让调度员通过站场图更清晰，明白的了解列车的实时状态是其中的重重之重。21289

Design for track layout system of CAD base on ATS
Abstract:With the development of technology， more and more people get used to using wireless communication technology， the wireless communication technology is also continued to develop very quickly. As a result， for the train control， the support of wireless communication technology is necessary.
Automatic Train Supervision (ATS system) is used to achieve the train monitoring and control systems. ATS can be implemented through the man-machine interface system through which the track layout displaying (ATS tracking layout displaying is the most important platform) for train control， and the ATS station map can react in real time the direction of travel of the train， driving mode， precise running position and operation of the equipment to ensure the safety of the traffic.
As currently the urban rail transit increasingly used， the safety of train driving is also more to be considered by the people. For example， Shanghai has appeared a variety of accidents， one of the most impressive which is happened on September 27th 2011， Metro Line 10 rear-end accident. Although it was mainly due to errors caused by the dispatcher， it is sufficient to prove the importance of the ATS system in the whole train operation system. It will be a good news if we can further improve the existing ATS systems for the railway industry， and the most important thing is how to help the dispatcher clearly and accurately understand the real time status through reading the track layout displaying.
This paper discusses the present situation of the development of train control systems (ATS)， the structure and function of the system， and then carries out a detailed analysis of the structure of ATS system， finally by using QT software to simulate the station graphics CAD software.
