DESIGN AND IMPLEMENTATION OF DIGITAL ELECTRONIC EXPERIMENTAL PLATFORM BASED ON ETHERCAT
To solve the problems in traditional electronic experimental teaching that errors exist in manual measurement and recording data,and one instructor is hard to tutor many students at the same time,a digital experimental platform based on EtherCAT is designed.A master multi-slave platform networking was constructed using EtherCAT.STM32F4 and LAN9252 were used to build the experimental terminal to collect and transmit experimental data,and a graphic wizard software was designed to provide students full guidance.The test results show the experimental platform has real-time and credible communication,accurate data acquisition,and one-to-one guidance for students,which offers a new way to realize digital teaching of electronic experiment and improve the quality of experiment teaching.
