以一个实际镍钴酸浸冶炼工业过程为对象,将工艺装置、阀门、检测仪表、执行机构、控制系统抽象成网络的节点,将物流管道、通信线路抽象成网络的边,进而形成复杂信息物理系统网络。通过统计分析,首次发现该生产系统网络的拓扑结构具备复杂网络的典型特征,即无标度特性和小世界特性,同时具有分层结构。最后,通过分析推测其它复杂流程生产信息物理系统所形成的网络也具备类似特征。
This paper first reports that the network topology of the cyber physical system of the nickel–cobalt acid leaching process is a scale-free, hierarchical, small-world network. The network topology is formed by mapping the processing units, valves, meters, actuators, and controllers as nodes and the communication cables and material stream pipes as edges. We speculate that this result may be valid for other complex processing system.
