Research Of Terminal Control Technology In Automatic Train Supervision System

With the rapid development of urban rail transit, domestic requirements and needs of automatic train supervision are gradually improved. Because our research is out-dated in automatic train control, we mainly introduced advanced foreign equipment and technology. The introduction made construction of urban rail transit costly, difficult to repair and mixed. To develop an ATS system with independent intellectual property rights will reduce the cost of urban rail traffic signal system. It will be the first step to make ATC system home-made.The research in supervision technology of terminal equipments─track circuits, signals, and switches, includes the following aspects:At first, summed up the background and significance of the research, the development situation at home and abroad. Analyzed the structure, functions, characteristics of ATS and introduced dispatching center ATS, station ATS and depot ATS. At the same time, analyzed the basic principles, manipulation ways etc. of terminal equipments. In addition, discussed the basic contents of route control and interlocking. And then, it did the modeling analysis to terminal equipment by object-oriented approach, UML and rational rose. Moreover, analyzed real-time control technology, storage structure of terminal equipment, interface painting technology, control technology of show time in the process of terminal equipment supervision and control. At last, the three-tier C/S architecture of terminal equipment supervision platform was designed. And completed the management of static data and dynamic data, achieved a simulation of real-time supervision and control of terminal equipment process.
