铁路专用线车地联控系统的研究与设计

车地联控系统是将计算机联锁,调度管理系统、车载设备中的信息综合起来进行一系列逻辑运算后,实现"车"与"地"的联控来保证机车安全运行,是结合了网络安全传输等技术的网络化、智能化、集成化的信号控制系统。车地联控系统各子系统之间具有独立性,便于系统的升级和维护;其中,地面终端子系统采用QNX操作系统,并将C++用以软件开发,可提高系统的效率和可靠性。其结构简单、运行稳定,可节省投资,目前该系统已研发完成并投入应用。

Research and Design of Train-Ground Integrated Control System on Railway Dedicated Lines

Train-ground integrated control system is a networked,intelligent,integrated signal control system in combination with network secure transmission and other technologies.By using it,and after carrying out a series of logical calculations on comprehensive system information,including computer interlocking system,train operation dispatching management system and onboard equipment system,the integrated controlling between the train and ground devices can be achieved to ensure locomotive safe operation.In addition,train-ground integrated control system is divided into several important subsystems and is independent among the various subsystems in favor of upgrade and maintenance.Moreover,QNX(Quick Unix) operating system and C++programming language are used in Ground Subsystem to realize software function and improve the system efficiency and reliability.Because of its simple structure,stable operation,low cost,the system has been developed completely and put into application.
