Study Of Ground Equipment Of Shunting Supervision Simulating System

Shunting work is an important part for railway transportation. It is an essential link to fulfill train makeup plan, train working diagram, speed up the turnover of vehicles and complete transportation mission splendidly. Also it is a job which involves a wide range, highly technology, high level and complication in shunting.At present, shunting in our country still adopt the way of semi-mechanization and semi-automatization in artificial work assisting part. Artificial judgement for various railway signal lacks of scientific and efficient method monitoring the operation condition of locomotive, so that it will lead to various accidents caused by human elements in shunting. So developing shunting supervision system to supervise real-time operation condition of locomotive is quite necessary. It can warn and alam the operation which is not fit for criterion and implement security controlled measure.Shunting supervision system is a control system which can ensure instation shunting security. It consists of land-based facility and vehicle-bone facility. Due to many uncertainties in the shunting operation process, it needs further validate for the initial status of key technics for vehicles, position tracing of shunting team, error cancelling of vehicle march and real-time system control. By building the ground equipment simulation system, analyzing the key technics of the ground equipment theoretically,it can help us to improve our system and its safety and reliability.This essay is mainly to complete the design and fulfill of shunting supervision land-based facilities of simulation system. Firstly, it will introduce the background and researches at home and abroad of shunting supervision system. Secondly, it will analyze the construct and function of shunting supervision system and the construction of designing simulation system land-based facilities. Thirdly, according to the construction of simulation system land-based facilities, this essay will analyse the function demands of land facilities and build up UML use-case diagram to make a detailed design of each function mould in land equipment, such as system data transmit, vehicle locomotion and tracing, multi-vehicles management and build up UML sequence diagram to make the data transmit of interlocking communication machine, land mainframe computer responder and on-board equipment audible by time sequence and make a detailed description of demand for the cases, build up UML activity diagram to describe the activity of using case instance and objects to illustrate the fulfill of use-case workflow and ensure it. Finally, according to the design of simulation system land equipment, it can complete the task of fulfilling each function of land equipment by using VC++program.
