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；
