The design of watt-hour meter verification assembly line based on CAN bus and Ethernet

This paper analyzes the current situation of watt-hour meter verification and proposes a design scheme of watt-hour meter verification line based on CAN bus and Ethernet. The verification line adopts modular design and the whole line is made up of three necessary verification links, namely withstand voltage verification, initial verification and repeat verification, achieving automatic connecting and disconnecting, automatic verification. A computer, the assembly line central control terminal,monitors the whole processes dynamically. Actual test results show the line's three links work orderly to make the verification process automatic and effective.
