基于REST服务的虚拟DCS平台

Virtual DCS Platform Based on REST Service

为解决虚拟DCS平台可重构能力差的问题,提出基于REST服务的虚拟DCS平台。首先给出基于REST的数据存取服务模型,其中包括模型的总体描述、数据对象元数据及客户端使用的方法。然后介绍DPU的建模方法,分析虚拟控制站和虚拟操作员站的实时数据流向,并在此基础上对虚拟DCS应用系统各站点之间的通信进行了优化。最后,通过一个实例验证了原型系统的可行性和正确性。

To solve the poor reconfigure ability in virtual DCS platform,a virtual DCS platform based on representational state transfer（REST） service is presented.Firstly,service model is built based on REST for data＇s storing and retrieving,which includes overall description,metadata of data object and methods used by client.And then,modeling method of DPU is introduced,and real-time data flow of virtual control station and virtual operator station is analyzed.On the basis of research above,how to optimize communication among stations of virtual DCS application is discussed.Finally,a sample is provided to verify the feasibility and correctness of the prototype model.
