Design of OPC/DDP-based remote monitoring system for environmental protection of the IoT

Abstract

With the acceleration of industrialization and the increasingly serious environmental problems, environmental protection of internet of things (EPIoT) has been recognized as an efficient way for developing green industries. By analyzing the OPC protocol for the data acquisition and the DDP communication protocol for the data transmission, this paper designs and implements an OPC/DDP-based monitoring system, including automatic monitoring on environmental data, efficient data acquisition, remote scheduling of devices, remote and real-time data visualization. Furthermore, the system uses a reverse proxy technique in data processing to achieve cross domain management and keep the session. The system effectively solves the problem of collecting data and visually displaying data under severe environment. In addition, the design process is optimized by the remote control. Finally, the system provides a reliable support on the decision for environmental management.
