| In recent years,with the continuous expansion of the coverage of China’s planned highspeed railway network,a large number of new high-speed railways and existing reconstruction lines have been put into operation,and high-speed railway signal equipment has been widely deployed and applied.Due to the increasingly significant trend of intelligent,electronic and modular high-speed railway signal equipment,the requirements for the professional quality of on-site electrical maintenance personnel are becoming more and more stringent.At present,the technical training mode for electrical maintenance personnel can not meet the current electrical maintenance needs,therefore,how to carry out high-quality and efficient training for railway signal maintenance personnel is an urgent problem to be solved.The traditional railway signal training mode has some problems,such as high training cost,low operability,imperfect training content and lack of unified management,therefore,the research and implementation of railway signal training system is of great significance to improve the quality and efficiency of railway signal training.The railway signal training system consists of interlocking simulation system,train control center simulation system,fault setting and case reproduction module and teaching management system.Based on the overall architecture and functional requirements of the railway signal training system,this thesis analyzes the requirements and structural design of the interlocking simulation system in the training system,and designs and implements the functions of the interlocking simulation subsystem on this basis.The specific research contents are as follows:(1)This thesis summarized the research status of train control and interlocking simulation training system at home and abroad,and put forward the overall architecture and functional requirements of the signaling training system.On this basis,combined with the functional requirements of the actual interlocking system,this thesis analyzed the requirements of the signaling training interlocking simulation system,established the system architecture model and designed and divided the functional modules,the overall design requirements and function realization objectives of each functional module of interlocking simulation subsystem were determined.(2)Based on the overall design of the interlocking simulation system,according to the interlocking control principle and railway signal technical specifications,the detailed design was carried out for the specific contents and implementation process of the interface display,operation command processing,interlocking function processing,analogue simulation and communication interface function modules of the interlocking simulation subsystem.(3)The station data,collected driving data and interlocking route data required by the interlocking simulation subsystem were designed.On this basis,the design and development of each functional module of the interlocking simulation subsystem was completed by using Visual Studio 2017 development platform combined with C++ programming language and QT framework,and the main functions of the interlocking simulation subsystem were tested with normal railway standard station and Huashan North high speed railway station as simulation stations. |
