Abstract


Shunting work is an important part of the production of railway transport, the train formation plan, train operation diagram accelerated vehicle turnover, an important part of good to complete the transportation task, while shunting operation is also a stop transportation work covers a wide range, highly technical , demanding and complicated task. At present, China's shunting operation are still using manual operations auxiliary part of the semi-mechanized and semi-automated job done manually on the judgment of the various railway signaling equipment state, lack of scientific and effective means of monitoring the locomotive's job situation can not be avoided job Thus, development the shunting monitoring system due to accidents caused by human factors, to the real-time monitoring locomotive operating that do not meet the job specifications and requirements given a warning, the police, and the implementation of automatic fault-oriented security control measures. Shunting monitoring system is a control system to ensure the safety of station shunting operation by ground equipment and vehicle equipment. There are many uncertain factors in the process of shunting operation monitoring system of shunting locomotives initial state determined shunting car column position tracking the locomotive running error elimination and control of key technologies such as real-time implementation effect needs further validation . Simulation system through the establishment of ground equipment, theory analysis of the key technologies of ground equipment, and help us to improve and perfect the system, to improve the safety and reliability of the system. In this paper, ground equipment to complete the shunting monitoring simulation system design and implementation. First, understand the background and research status the shunting monitoring system. Followed by analysis of the structure of the the shunting monitoring system structure and function, design and simulation system ground equipment. Again based on the structure of the simulation system ground equipment of the analysis of ground equipment function needs to create a UML use case diagram; detailed design of the ground equipment of various functional modules, such as the system of data transmission, the locomotive positioning and tracking of multiple locomotives of management; create UML Sequence diagram, the data transmission between the interlock communication unit, ground host, the transponder and the vehicle device in chronological sequence visual representation of the detailed description of the use cases expressed needs; create a UML activity diagram, describing Examples of the use cases, the activity of the object, clarify the system use-case realization workflow, to determine the system's workflow. Finally, in accordance with the design of the simulation system ground equipment, the VC programming the various functions of the ground equipment.
