摘　　要：分析了国内外CBTC(基于通信的列车控制)系统的结构特点。针对典型CBTC系统存在的问题,着重分析了CBI(计算机联锁)和ZC(区域控制器)均采用同一硬件和同一软件的轨旁控制子系统一体化方案,给出了该方案下轨旁控制子系统为列车计算行车许可的方法。最后对一体化的CBTC系统与典型CBTC系统下开放信号机、关闭信号机、人工解锁进路、解锁保护区段及CBI采集列车包络占用区段延时检测等功能的实现方式进行对比。对比结果表明,采用轨旁控制子系统一体化方案的CBTC系统可以减少子系统间的接口,降低ZC和CBI间的功能耦合度,提高系统的运行效率。The structure characteristics of domestic and worldwide CBTC(Communication-Based Train Control)systems are analyzed.Targeting problems existing in typical CBTC systems,the scheme of trackside control subsystem integration where CBI and ZC adopt same hardware and software is analyzed with emphasis.A MA(movement authority)computation method of trackside control subsystem under this scheme is put forward.In the end,the proposed system is compared with the typical CBTC system in the realization method of functions including opening the signal,closing the signal,manually releasing the route,releasing the protection section and delay detection of the CBI acquisition section occupation-based train position.Results show that the newly proposed CBTC system integrating trackside control subsystems improves system operation efficiency by reducing subsystem interfaces and lowering ZC software and CBI software function coupling.
