摘要:
［目的］针对地下车站设备双端布局的结构特点，为充分利用BAS（环境与设备监控系统）的A、B端PLC（可编程逻辑控制器）设备配置，并最大程度增加系统冗余程度，特对车站环境与设备监控系统组网优化及多重冗余方案进行研究。［方法］提出了一种地铁BAS和PLC组网优化及多重冗余实现方法。该方法通过多控制器与远程I/O（输入/输出）无差别组网、PLC多重冗余架构及运行策略优化，对原有系统架构进行了改进。［结果及结论］优化后的系统能够有效避免主端PLC失效后车站BAS系统处于失控状态的问题，提升了系统的整体可靠性和应急联动能力。尤其是在极端情况下，优化后的系统能够最大限度保证应急模式的稳定执行，从而有效保障车站的运行安全。

［Objective］ In response to the structural characteristics of the dual end layout for underground station equipment, fully utilize the configuration of BAS (building automation system) A-end and B-end PLC (programmable logic controller) equipment, and maximize the system redundancy, a networking optimization and multi-level redundancy scheme for station BAS is investigated. ［Method］ A method of implementing the networking optimization and multi-level redundancy for metro BAS and PLC systems is proposed. This method improves the original system architecture through non-differentiated networking of multiple controllers and remote I/O (input/output), multi-level PLC redundancy architecture, and operational strategy optimization. ［Result & Conclusion］ The optimized system effectively prevents station BAS from becoming uncontrollable in the event of a master PLC failure, thereby enhancing the overall system reliability and emergency response capability. In particular, under extreme conditions, the optimized system ensures the stable execution of emergency modes to the greatest extent possible, effectively safeguarding station operational safety.
