| The computer-based interlocking system composed of indoor and outdoor station equipment is used to implement the interlocking logical control of station transportation operations,which plays a considerable part in modern railway signal system.With the rapid development of computer simulation and virtual reality technology,the 3D simulated applications for railway signal system continuously evolve.Accomplished by 3D simulation technique for mechanical structure and action of interlocking outdoor signal device,a vivid3 D station is stereoscopically constructed,which helps to reduce the dependence on practical equipment and the training cost of railway technicians.Combined with the computer-based interlocking software to master the interlocking control of virtual signal equipment,it’s available for users to simulate station transportation operations in 3D station,which can more intuitively show the interlocking logic control function,and also be used for functional verification of the interlocking system.With a foundation of computer-based interlocking system,this thesis,which refers to the simulated functional design for entities within virtual station,mainly researches on the interaction pattern between interlocking system and 3D station and realizes the interlocking control of virtual station signal equipment.On that basis,the system master control software is implemented.By studying the process of station transportation operations,this thesis devises the simulated running control function for station transportation in the system master control software where the function of multiple stations synchronous switching is also built to reappear various station operations in the interlocking integrated simulation system.The main work of this thesis as follows:(1)Complete the design of the universal interlocking integrated simulation system based on 3D station.With the implementation of system master control software,this thesis compiles the plans for train running and locomotive dispatching,gets the control of simulated running in the computer-based interlocking system and the 3D station,as well as achieves the multiple stations switching.(2)Implement the system network communication interface includes network data frame and communication mechanism.A complete integrated simulation platform of interlocking system is built over the data interaction within the system master control software,computer-based interlocking system and 3D station.(3)For functions such as station operation plan compilation,signal equipment monitoring,train running control and multiple stations switching,the specific software design is combined with the train dispatching theory and interlocking control principle,and the basic functions of the system master control software can be realized by VC++ integrated developing environment.The simulation control for station operations of the interlocking integrated simulation system is performed in the 3D scene,including train and locomotive dispatching operation.(4)Devise the procedure of station switching by analysis on the software data reading process and the station data configuration of the simulation system.With the help of station data generation software that configures multiple station for the interlocking integrated simulation system,it’s convenient for system to complete the station switching and data uniformity. |
