重载铁路移动闭塞计算机联锁系统研究

针对重载铁路移动闭塞系统的特点和技术要求,基于朔黄铁路既有线路中使用的DS6-K5B型计算机联锁系统,通过对既有联锁系统功能进行升级和改造,以满足移动闭塞系统的控制要求。联锁系统升级和改造功能包括多列车进路的办理和解锁,信号机点灭灯控制,物理区段与逻辑区段状态的融合;根据移动闭塞需求,增加联锁与RBC设备的接口,修改联锁与CTC、CSM设备的接口。改造后的联锁系统兼容既有运输模式,同时实现重载移动闭塞及固定闭塞混运的功能。

Research on Computer Based Interlocking System for Moving Block System of Heavy Haul Railway

According to the characteristics and technical requirements of the moving block system of heavy-haul railway,based on the DS6-K5B computer based interlocking system used in existing lines of Shuozhou-Huanghua railway,the functions of the existing interlocking system are upgraded to meet the requirements of the moving block system control.The CBI upgraded functions include the setting and releasing of multiple train routes,the control of signal lighting on and off,and the combination of physical and logical section status.The interface between the CBI and RBC equipment is added,and the interfaces between CBI and CTC,CBI and CSM equipment are modified according to the requirements of moving block.The upgraded CBI system is compatible with the existing transportation modes,and at the same time realizes the mixed transportation function of heavy-haul moving block and fixed block.
