Research On Simulation System Of Railway Technical Operation Standard Time

Recent years, with the rapid development of China’s railway, the demand of passenger transport volume is growing, and technology operation standard time has greatly reduced than that in the past. However, the technology operation standard time of China’s railway is artificial established, without scientific instruments. This technology operation standard time does not match actual, which cause train habitually delays and reduce the capacity of railway. How to scientifically and effectively formulate the technical operation standard time is a serious problem.With the development of computer simulation technology and characteristics of small investment, risk-free, remarkable, computer simulation technology is widely used in various fields. This paper simulates train traveling of railway technical operations with the use of computer simulation technology simulation, and formulates technical operations standard time with scientific methods. Railway technical operation standard time simulation system is a platform which simulates railway technology operation procedure, and shows the device status intuitively based on railway network graphics. The simulation can analyze and found problems in the course of technical operations, and determine the technical operations standard time, test the rationality of parameters of train operation diagram, and provide decisions for the railway personnel, and improve the efficiency of the transport organization.Based on the analysis of domestic and international simulation of railway train running, this paper made more thorough research of technology operation standard time simulation system. First, determine the simulation method of technology operation based on the theory of simulation. It describes the content of technology operation, and points out the target of simulation system. Secondly, analysis the needs of the function of system, database, operating environment, security, and performance based on a user’s feature.Then, analysis and determine the model and algorithm of train control in traction calculation theory. The article points a calculation method of technology operation time, and discusses some key technologies in-depth such as train simulation control, interlocking relationships of infrastructure and the control method of simulation system clock based on train diagram. This article takes an outline design in terms of system simulation program, the overall structure, the simulation strategy, interfaces, etc. Then, identified three subsystems, and detailed design the three subsystems and each subsystem module, descript transmitted data between the various modules according to the link between each other. Analysis system simulation process, and design the system database and user interface.Finally, this article summarizes the work which has been done and points out the problems should be solved in the next work.
