Study And Implementation Of Some Key Problesm In Marshalling Station Operation Sim-system

In this paper, a simulation platform of railway marshalling station is constructed in the background of transportation production process of marshalling station. The platform aims at cultivating technology management talents and scientific research.In order to realize the simulation demonstration of the process of station operation and parts of the functions of marshalling yards, and to acheave lively simulation in the maximal degree, technology of computer simulation, database and orient object programming are used to analyze and program the platform of marshalling simulation. On this basis, futher research of theories in the railway field and development of railway simulation can be carried out.The main contents in this paper are as follows:1. In the representing system, object oriented modeling technology is used to construct digital schematic diagram of marshalling station and process control system model.2. In the diagram of the station,dynamic display of the process of station operation based on the visualized method of promoting the band of light. With the computer simulation technology, dynamic simulation of railway station operation is realized based on the diagram of the station.3. Interlocking information is analized and integrated based on database technology, and virtual interlock of station equipment is realized.4. With the modular programming method, functions of arrangement,cancel, manual unlock and time-delay unlock are simulized on the marshalling station simulation platform.5. The function of individual operation of railway station equipment, like signal and switch, is also developed.
