Method Comparison and Interface Exploiture of Intelligent Electrical Apparatus Connected to EtherNet
Zichi Zhang · Low Voltage Apparatus · 2007
Three different kinds of method of the lowest field apparatus connected to EtherNet were analyzed. Considering the requirement of the open, agility and reliability of intelligent electrical apparatus network and the fact of intelligent electrical apparatuses with serial communication interface, a design scheme was adopted, in which the intelligent electrical apparatus was connected to EtherNet by a special EtherNet communication interface, and a kind of interface based on the microprocessor of ARM was developed.
