| Using modern Internet of things,Internet and communication technology to promote the progress of teaching technology is one of the contents of educational research and in-depth research.In engineering experiment teaching,students’ practical activities are often affected by time and space,and there are management problems in teaching experiment instruments and equipment.The purpose is to improve the traditional teaching method of electrical and electronic experiment and further improve the teaching quality.This paper also designs a remote operation practice teaching platform to realize the teaching of simulation circuit and microcomputer principle.The system combines electronic communication technology with network,which fully embodies the concept of "science and technology serving teaching and learning".Using modular thinking,this paper abstracts the remote operation test platform into three parts: test terminal,equipment terminal and network server,and realizes good scalability and maintainability through B / S structure.At the same time,the product design of equipment port mainly involves the product design of program-controlled power supply,simple signal controller,oscilloscope and functional gateway module system.The product integrates embedded web server equipment,wireless serial port and field tested video image observation system.In order to overcome the shortage of remote test station,the product design based on management module system is based on the test interface and application of ARM MCU at the service end.This product designs several typical circuit test interfaces for the simulation circuit.The server design adopts the development mode of separating the front and back stages to realize multi experimental pages,good experience and preliminary paperless classroom experimental system;At the end of the experiment,an unmanned simulation transmission amplifier circuit for remotely changing the circuit structure and key component parameters is designed,and an arm microchip experimental platform with remote download program is designed.The experimental platform designed in this paper can realize the open sharing of experimental resources,so that students can enter the paperless classroom for experimental learning anytime and anywhere. |
