摘要:
简述了VIOP(安全输入输出平台)的架构，对双系冗余VIOP的系统接口、模块组成、内外部通信连接状况，以及通过VIOP的双系热备AM(采集模块)实现对同一继电器节点状态的分时采集原理，通过双系热备DM(驱动模块)实现双断驱动原理等关键技术进行了介绍。简述了VIOP的整体冗余网络架构以及VIOP诊断维护功能。重点对采用VIOP的iLOCK-200T型道岔控制器在深圳龙华现代有轨电车示范线项目SmarTram信号系统中的应用情况进行了介绍。描述了龙华现代有轨电车大和站的1个主逻辑单元带多个VIOP的架构配置情况和工作原理。对后续VIOP迭代的技术方案进行了展望，指出未来可以考虑通过远程更新、网络通信远程部署等方式降低成本，实现道岔控制器的精简与高效控制。
Abstracts:
The architecture of VIOP (vital input/output platform) is introduced briefly. Some key technologies are introduced, including dual-system redundant VIOP system interface, module composition, internal-external communication connection status, time-sharing acquisition principle of the same relay node states realized through VIOP dual-system hot-standby AM (acquisition module), and dual-break drive principle realized through dual-system hot-standby DM (drive module). The whole redundant network architecture of VIOP and VIOP diagnostic maintenance function are briefly introduced. Then the application of iLOCK-200T switch controller with VIOP in SmarTram signaling system of Shenzhen Longhua Modern Tram Demonstration Line project is emphatically introduced. The architecture configuration and working principle of one main logic unit with multiple VIOP at Longhua Modern Tram Dahe Station are described. The technical scheme of the next VIOP iteration is prospected. It is pointed out that the cost can be reduced by remote updating and network communication remote deployment in the future, realizing simple and efficient control of switch controller.
