Research And Implementation Of Internet Of Things Training Platform

With the popularization and construction of 5G,the Internet of things has become a new industry in the future.The Internet of things has been extended to people’s daily life,and people’s life style has been improved.At present,the education of Internet of things in China has just started.When the major universities establish the major of Internet of things,vocational colleges also have the construction of the major of Internet of things.At present,there are few training platforms for the major of Internet of things in the market,but most of them are for undergraduate education.The lack of training platform restricts the construction of the Internet of things specialty in vocational education to a certain extent.The demand for the experimental platform in the teaching of the Internet of things specialty is increasing,so the development of the Internet of things training platform for vocational education has become an urgent problem to be solved.This paper analyzes the current situation of the Internet of things teaching platform,solves the difficulties and problems existing in the current Internet of things experimental platform,and puts forward solutions based on micro Python for the sensing layer,transmission layer and application layer.Combining sensor technology,mqtt technology,esp32 embedded technology and onenet platform of China Mobile,this paper proposes a set of intelligent Internet of things platform solutions for vocational education students.First,modular hardware design.MCU adopts the embedded chip esp32 with WiFi and Bluetooth as the main control MCU,which can realize Bluetooth ad hoc network and wireless WiFi network,save hardware cost and reduce the learning difficulty of students.Use buttons,light sensors,temperature and humidity sensors,RFID modules and other sensing layer components to combine into multiple sets of IOT solutions,which can form IOT training scenarios for various situations and form large-scale IOT training projects.Second,micro Python is used as the main programming language of the platform.Due to the poor basic knowledge of vocational college students,especially in secondary vocational education,students generally have not learned the relevant computer knowledge.Therefore,it is easy to arouse the students’ interest by starting with a relatively simple micro Python language.Third,the use of the latest mqtt and other communication technologies combined with China Mobile onenet platform can enable students to master the latest Internet of things communication protocol.In the process of using onenet platform,students can create their own Internet of things applications by themselves,which greatly reduces the learning threshold.Finally,after a semester of use,through structured access to the use of different levels of interviews,summed up the use of the platform,pointed out the advantages and disadvantages of the platform,and made prospects for future improvement of the platform.
