Application Research Of Data Process Related Technology In CPS

Cyber Physical System (CPS) is the next generation intelligent system with high reliability,security and efficiency which integrates Computing, Communication and Control. The significanceof CPS is connecting physical equipments to network, especially to Internet, which makes thephysical equipments have computing, communication, precise control, remote coordination andautonomous functions. But there is not any unified architecture for CPS to process computer system,network system and physical system. The physical equipments typically have characteristics ofsense and control, so the format of collection data is inconsistent and the amount is large. How toprocess these data in CPS is the main work of this thesis.Internet of Vehicles (IOV) is one of the mature applicaton systems in CPS. After research oncharacteristic of IOV collection data format and comparison to IEC61968-9standard, a uniformIOV data format based on XML was defined. To resolve pressure on network and storage by bigdata, a data share model based on web service was proposed in this thesis for application programof IOV.The data share platform model for IOV based on XML and web service was designed andimplemented by using gSOAP framework. The model was improved by optimizing the process ofdata request, which improves the efficiency of data share platform. Practices proves that the datashare platform model based on XML and web service can resolve the issues which make sharing ofIOV data difficult either make pressure on network and storage. Both XML and web service areplatform independent, so this program will be suitable for other CPS systems.
