160 km/h城际车采用符合TCN标准的MVB总线结构,实现了关键设备冗余。网络设备端口尺寸和轮询周期采用了最优化分配,根据网络设备端口统计结果,计算得到了网络负载率,结果表明可保证列车可靠实时通信。介绍了VCU软件配套使用的服务软件,可以通过服务软件在线监测MVB数据和设置VCU网络参数。对VCU的软件架构设计进行了介绍,VCU控制逻辑基于Openpcs平台,为高速应用提供了性能保证。
The 160 km / h intercity bus uses the TCN-compliant MVB bus architecture to achieve critical plant redundancy. Network equipment port size and polling cycle using the optimal allocation, according to the network equipment port statistics, calculated the network load rate, the results show that the train can ensure reliable real-time communication. Introduces the service software used by the VCU software to monitor MVB data and set VCU network parameters online through service software. The software architecture design of VCU is introduced. VCU control logic is based on Openpcs platform and provides performance guarantee for high-speed applications.
