In this paper, we will design a set of standard communication protocols that can be used in different electric energy metering device environments by analyzing the communication protocols of the most used electric energy metering devices in the context of IoT smart laboratory construction, so that the electric energy metering devices can automatically detect the inspected equipment. It achieves the purpose of promoting the construction of a smart laboratory, enhancing the management of electric energy metering devices, and improving the efficiency of metering activities. It provides strong support for forming an automated, intelligent and industrialized testing system.
