地铁作为城市公共交通的主动脉,保障其安全性和可靠性尤其重要。研究着眼于门禁控制这一细分领域,采用CAN总线双环网设计、冗余控制设计和双电源冗余电源。轨道交通门禁环网控制与冗余切换系统根据集中管理、分散控制的原理,遵循人性化的工作模式,采用管理、控制及操作的层次模型,克服了大规模系统的信息安全瓶颈,提高了响应速度和产品的稳定性。
Metro as the aorta of urban public transport, to ensure its safety and reliability is particularly important. Research focuses on access control of this sub-area, the use of CAN bus double loop network design, redundant control design and dual power redundant power supply. According to the principles of centralized management and decentralized control, following the humane mode of operation, the hierarchical model of management, control and operation of the rail transit access ring network control and redundancy switching system overcomes the information security bottleneck of large-scale system and improves the response Speed and product stability.
