摘要:
［目的］列车自主运行系统车载控制器发生故障时，无法正常完成轨旁资源申请及释放。对此，有必要提出一种基于后备定位系统的主动资源申请和释放方法。［方法］增加后备定位系统与车载控制器的接口后，在主用车载控制器失效时，后备定位系统能够继承原有任务并控制轨旁资源。重点研究了主用车载控制器与后备定位系统之间的切换机制，以及后备定位系统在资源申请和释放、列车间隔防护方面的技术实现。阐述了后备定位系统的总体设计，以及后备定位系统与车载控制器的接口设计。［结果及结论］该方法能够有效简化系统架构，减少轨旁列车管理器故障的影响，同时保持列车自主运行系统车与车之间直接通信的模式不变。
Abstracts:
［Objective］ When the onboard controller in TACS (train autonomous circumnavigation system) fails, the trackside resource request and release cannot be carried out successfully. Regarding this, it is necessary to propose a method for active resource request and release based on the backup localization system (hereinafter shorten as BLS). ［Method］ An interface between the BLS and the onboard controller is added, enabling the BLS to inherit original tasks and control trackside resources when the primary onboard controller fails. The switchover mechanism between the primary on-board controller and the BLS is emphasized, as well as the technical implementation of resource request and release, and train interval protection by the BLS. The overall design of the BLS and the interface design between the BLS and onboard controller are elaborated. ［Result & Conclusion］ The proposed method effectively simplifies the system architecture, reduces the impact of trackside train manager failures, while maintaining the existing train-to-train direct communication mode in TACS.
