Design And Implementation Of Analysis Query System Of Flow Of Freight Trains Illegally

With the application of large quantities of modern railway technology and equipment, railway transport density increasing, dispatchers and cargo marshalling yard ledger used in manual mode can not meet the requirements of the railway by leaps and bounds. In order to reduce locomotive and transit times, avoid the waste of transport capacity and improve rail transportation efficiency and enhance economic efficiency, the design against the flow of freight trains compiled against the system, how the design and analysis is the focus of this article.Purpose of the railway network traffic distribution line of traffic and access to road network traffic routing plan, are network optimization problems, is the basis for road network planning, organization of railway transport plays an important role in supporting guidance. This in-depth distribution of the railway network traffic system and the optimization theory based on the characteristics of railway transportation in our country, first analyzes the main railway marshalling scheme related factors, described the railway traffic path allocation method, described by Dijkstra algorithm as the basis of the railway network the shortest path between any two points solution calculation Threshold as a search through the use of restraint, to search along the shortest path from start to finish direction, eliminating unnecessary search process, saving search of time and increase the efficiency of solving the shortest path algorithm.This in-depth distribution of the railway network traffic system and the optimization theory based on the combination of the factors that this paper discusses the system itself system objectives, functions, design and hardware and software environment, and traffic flow path of knowledge representation and generation methods for the detail. Finally, the background program is indeed implemented by the computer analysis of the train reported that the final plan for the transportation compilers provide access to in their daily work basis, while improving the quality of marshalling yard marshalling and improve the efficiency of railway transport and economic benefits.
