Scalable Real-time Data Interface With Application to Android Based on OPC for IOT

Traditional industrial data interface follows the object linking and embedding for Process Control (OPC) standard and relies on the personal computers or on-site computers, which has some limitations, e.g., the dependence of Windows platform, too much service couplings, and inflexible usages. There is few researches on scalable real-time data interface with other platforms, and an efficient and scalable real-time data interface that supports mobile applications is one of the key technologies to be solved in software engineering for Internet of Things(IOT). So in this paper, we consider scalable real-time data interface with application to Android, based on OPC. We develop an architecture of the scalable real-time data interface by sufficient analysis, and then present several corresponding modules on Android for application. Finally, we test our designed scalable real-time data interface based on a process control device, and apply it to Android platform. The results show that our designed scalable real-time data interface is practical and efficient.
