Abstract: In order to improve the practice teaching conditions of the electrical automation,and develop training devices to meet the school’s teaching practice,forming a set of basic experiments,verifying experiments,practice and training,the design innovation as one of the training devices.This paper introduces the basic idea of the reconstruction,reforming contents and the specific implementation process of transformation.Reform training devices of the opto-mechatronics system based on N:N network as the master station of manipulator.Feeding unit and sorting unit are treated as two slave stations.By means of the practice training using this device,the students can understand the PLC and its functional module application technology,electric control technology,inverter technology,sensor technology,touch screen and configuration technology industrial control technology,etc.
