Fully-automatic verification system for intelligent electric energy meters

摘要

A fully-automatic verification system for intelligent electric energy meters comprises a plurality of verification units for automatic verification of the electric energy meters, main transport lines for connecting the verification units, and a verification management system for coordinating the work of the verification units. The main transport lines comprise upper transport lines for transporting boxes carrying electric energy meters to be verified to the verification units and lower transport lines for transporting the boxes carrying the electric energy meters back to the warehouse. The verification system for electric energy meters can implement fully-automatic verification, thus enhancing the efficiency and the verification accuracy.
