The Design and Performance Test of Train Control Data Communication Systems Based on Train-to-Train Communication

Communication Based Train Control (CBTC) systems are signal systems to ensure the safe operation of rail transit. However, with the increasing demand for the efficiency of rail transit operations. the train control system based on train-to-ground communication has exposed many problems such as complex system structure and high construction cost. Compared with the train control system based on train-to-ground communication, the train control system based on train-to-train (T2T) communication has advantages of fast response speed, simple structure, and low operating cost. The data communication, which is the core part of the train control system based on T2T communication, realizes continuous and large-capacity two-way communication between equipment in the system which is of great significance for ensuring the safety and efficiency of the train operation. According to the requirements of the train control system based on T2T communication, the Long Term Evolution (LTE) technology is applied in this thesis to design a data communication system structure based on T2T communication. In addition, a performance testing platform is established to test system performance at the same time.
