Functional Simulation Of Hump Yard Interlocking Upper Computer

Railway marshalling station operations as an important part of railway transportation the main task is to complete the disintegration of train columns and the reorganization of train columns,marshalling yard operation is multifarious and has a number of links,which requires operating personnel have to be familiar with the operation process. So it has significant meaning to train operating personnel to be skilled at the operating system of marshalling yard, which increasing the work effciengcy of marshalling yard operation.The simulation software development of the function of upper computer of the interlocking system in hump yard, which apply computer simulation technology to the simulation of Hump Yard operation,has the advantages of low cost and high safety.and a significant impact on the transport operators to improve the efficiency of marshalling station.This thesis take the Hump Yard as research object to conduct the functional design of the upper computer, by analyzing the process of hump yard operation and the structures and operative principles of the upper computer,the simulation of hump yard operation utilizing Delphi to develop the upper pc control-software and SQ1 Server 2000 to design the operating sheet of planning is implementation.At first, the paper gives analysis to the requirement functions of upper pc control-software,The function of upper pc control-software is divided into six functional modules,which includes data initialization module, display module, function command module,communication module, operating sheet of station module and simulation of the rolling process of wagons module.the data initialization module is mainly for the structural design and the initialization of the static data of signal equipment;drawing of hump yard and designing of menu buttons are explained in display module; The function command module gives the procedure of handling the command; in the module of communcation, the communication method between the upper computer and low-computer in Hump Yard is TCP/IP,so is the communication between the upper computer and upper computer in Receiving-Arriving Yard;operating sheet of station module’s job is to connect the upper pc control-software to the local database, the upper pc analyze the content of operating sheet and get the command of the route selection,in the last module, According to the characteristics and modes of hump operation, realize the whole dynamic process of humping operation.Then on the basis of the above function module, using the software to realize the function.Finally, testing the function of the software The test results show that the software runs well and can realize the basic function of the upper computer and the simluation of the hump operation.
