Dynamic Adjustment Mechanism based on OPC-UA Architecture for IIoT Applications

摘要

In much smart Industry Internet of Things (IIoT) applications, there are many emergencies information processing e.g. fire and urgent accidents. However, when data which is from different source and format is lack of collation, integration and preprocess, the server loading will be too heave to process the information on time. This study mainly proposes to establish an Open Platform Communications Unified Architecture (OPC UA) architecture system for IIoT application design and introduces a dynamic node adjustment mechanism to be applied under the OPC UA architecture. The dynamic adjustment node is designed with network bandwidth monitor to solve the problem of excessive network load caused by emergency information transmission in the IIoT applications.
