Data transmission scheme of real-time control CPS based on software defined resources

信息物理融合系统CPS是当前最前沿的交叉研究领域之一,具有广泛的应用前景,其研究和发展离不开数据传输与管理技术的支持。提出了一种基于软件定义资源的CPS模型,通过采用映射资源描述文件的方式实现资源的分配与调度;在此模型的基础上提出了一种实时控制CPS数据传输模式,这种数据传输模式以中间件形式实现,中间件对CPS的消息采用序列化与反序列化的机制传输,可以满足CPS跨平台、跨网络、实时性的要求;设计了一种CPS消息传输的路径,以提高传输效率。实验结果表明,所提出的数据传输序列化机制是可行的。

Cyber-Physical System （CPS） is currently one of the forefronts of cross research fields. It has wide application prospect, and its research and development cannot continue without the support of data transmission and management technology. In this paper, we propose a model of CPS based on soft- ware defined resources. The allocation and scheduling of resources is implemented through the way of u- sing mapping resource description files. On the basis of this model, we present a data transmission mode of controlling the CPS in real time. This data transmission mode is implemented by middleware. This middleware employs a kind of serialization and deserialization methods in CPS, which is able to meet the requests of cross-platform, across networks and real-time communication in CPS. Besides, the paths of data transmission in CPS are designed in order to improve the efficiency of communication. Experimental results show that the serialization mechanism of data transmission is feasible. Key words： CPS; software defined resource; real-time system; data transmission scheme; cross platform
