A reliable, efficient, and stable metrology IoT platform is an important part of the digital transformation of smart manufacturing enterprises. 6LoWPAN is a low-speed wireless personal area network standard based on IPv6, which provides a good platform for the construction of metrology IoT. In this paper, we design a metrology IoT based on 6LoWPAN for smart manufacturing enterprise applications, including the topology design of metrology IoT, the design of RPL clustering routing protocol, the design of load balancing mechanism, and the self-organizing network construction scheme. The nodes of this system can form a cluster network topology, and the gateway aggregates the data of each node and displays the collected metrology monitoring data in real time. Simulation experiments and results verify the load balancing and multi-node networking operation of the designed metrology IoT.
