Industrial Internet of Things Multi-Protocol Convergence Gateway Research and Experiment
Li Ma, Zhaoyuan Xiu · 2020
IIOT(The Industrial Internet of Things) is an important infrastructure in the Industry 4. 0 strategy. After years of development, a number of independent Industrial Internet of Things standards have been established. The different standards of the Industrial Internet of Things cannot communicate with each other, which brings difficulties to centralize monitoring and control. To solve this problem, first, we proposed a multi-protocol converged gateway to convert various IIOT protocol datagram. Secondly, we created a software architecture and gateway data processing process for the conversion between different industrial Internet of things protocol data formats. Finally, we designed a converged gateway architecture and embedded a transformation layer in the existing protocols to form a converged Internet of things gateway and realize data intercommunication between different protocols. At the same time, for industrial Internet of things nodes that do not have IPv6 addresses, we used the method of virtual IPv6 address to enable node messages to communicate with other IP networks or non-ip networks, and gave an addressing scheme of the IPv6 address. We verified that the converged gateway solution is possible and the results are satisfactory through real node experiments. lt is a feasible solution to realize the conversion between the existing industrial Internet of Things standards.
