Scope: This document sets out the design principles and objectives, business models, and hierarchies of the automatic loading and unloading system for electric energy metering devices, and specifies the technical requirements for unitized logistics, data standardization of container units, data interfaces, data collection, video surveillance, automatic loading and unloading equipment, and safe operation and maintenance of the automatic loading and unloading system for electric energy metering devices. This document is applicable to the business management of the automatic loading and unloading system for electric energy metering devices in electric energy metering verification centers. Main technical content: An electric energy metering device (EEMD) is a device used for measuring electric energy, consisting of various types of electric energy meters or meters connected to voltage and current transformers (or dedicated secondary windings) and their secondary circuits, including single-phase electric energy meters, three-phase electric energy meters, low-voltage current transformers, load management terminals, distribution transformer monitoring and metering terminals, and concentrators. The Guangdong Power Grid Company Metering Center is currently the largest, most capable, and technologically advanced provincial electric energy metering verification center in China, responsible for the verification and testing of electric energy metering equipment in Guangdong Province. With the increasing scale and number of equipment in the metering verification center, verification personnel need to travel back and forth to conduct verification work, which is costly and inefficient. The Guangdong Power Grid Company Metering Center has built an automated verification assembly line and corresponding automated loading and unloading and intelligent warehouse storage systems, enabling the automated verification of large batches of electric energy meters and greatly improving the ef
