Development And Application Of Of Enterprise Railway Shunting Operating System Based On Gis

PetroChina Lanzhou Petrochemical Chemical storage factory railway line, is mainly responsible for the western district of Lanzhou Petrochemical Company material to reach,and large areas of solid marketing in products shipped rail transport. After the completion of the ethylene in 2006, chemical storage factory railway line in 2004 will be annual throughput of 1.27 million tons per year by to 3.7 million tons per year. Because of the substantial increase in traffic makes the chemical storage factory production and management of existing transport modes must be corresponding changes to the traditional command model railway shunting low efficiency, high error rate, there is a big security risk. Difficult to meet the transport needs after 2006, only the use of advanced science and technology combined with the actual situation of chemical storage factory to build a modern storage management control information platform as a whole to adapt to a large ethylene project goes into operation and the new transport situation.This issue is based on the railway station dispatching the specific characteristics of station command and control objects in space showed a typical point, line, surface distribution, and there are still between geographically close and logical relationship. Therefore, relying on geographic information systems (GIS) technology to efficiently manage these spatial information and analysis to build a railway station shunting command platform, the platform to establish the traditional shunting operations planning process in the collection vehicle information and updated by the full manual mode, the current car into a station vehicle information data transmission, graphical operations. Organization created for the optimization of transport conditions, to improve transport services and create the conditions for economic efficiencThis follows the general process of software development, which is divided into needs analysis, modeling, outline design, detailed design, coding, unit testing, system testing, installation and acceptance, the effect of several stages of the software application is described. Detailed software design, including specific database design, interface design, detailed functional description. Focuses on the database table design, data flow, the specific interface design, software model (C / S mode), etc. The software put into use in the formal work, fundamentally changed the travel command dispatcher to work hand-written program, manually update the current vehicle data work to improve the planning of shunting efficiency to achieve a shunting operation plan the preparation of the accuracy and efficiency.
