摘要：随着铁路信息化的发展，车地数据通信的地位也日趋重要。铁路作为一个大型的交通运输联动机，在组织、运输、经营管理、客货营销等各项活动中，人与人、人与设备、设备与设备之间的信息交互应用广泛。而现代化铁路对车地通信的要求也越来越高，包括它的可靠性、时效性等等。车地数据通信系统只有准确、及时地对列车运行中的各种数据进行访问，这样才能实现列车的远程故障诊断和实时监控等功能。。车地数据通信系统承担着铁路运行中的列车与外面数据交互的“纽带”作用，在公共的安全管理方面提高列车运行效率等方面都占据着重要的角色。41392

The Design Of Locomotive-Ground Data Transmission For Rail Transit
Abstract：With the development of railway informatization, the position of Locomotive-Ground Date Transmission is becoming more and more important. Railway as a large transportation linkage machine, in the activities of the organization, transportation, management, passenger and freight marketing, the application of information exchange between people and people, people and equipment, equipment and equipment are widely. And the requirement of modern railways to Locomotive-Ground Date Transmission is getting higher and higher. The safety, efficiency and comfort of the it is generally concerned by the society. The Locomotive-Ground Date Transmission system can achieve this function of real time monitoring of train and emote fault diagnosis，only get all kinds of data in the train operation accurately and timely. The Locomotive-Ground Date Transmission system is responsible for the connection between the train and the external information, and it plays an imp orient role in the management of public safety, improving the efficiency of train operation and improving the experience of passenger travel.
This topic is designed to research signal transmission method of Locomotive-Ground Data Transmission For Rail Transit, like transponder track circuit, GSM-R, etc. And, compares and analysis them. Aiming at the real-time and reliability of Locomotive-Ground Date Transmission, study the architecture of Locomotive-Ground Date Transmission and analysis of the current situation of it. Finally，design a communication signal transmission scheme for high speed railway.
Key Word: Locomotive-Ground Data Transmission; rail transit; rail transit; GSM-R；GPRS；
