Development and Practice of Mobile Internet Experimental Platform System

Abstract

<p>As an emerging technology, mobile Internet technology involves almost all knowledge points in the application field of computer science and technology. The traditional Internet of things experiment box based on embedded technology has single equipment and limited functions, which can not meet the experimental requirements of mobile Internet from data perception, transmission to application. Aiming at the lack or incompleteness of the experimental platform in mobile internet teaching, a set of mobile Internet experimental platform system is designed. The platform is built according to the three levels of perception layer, transmission layer and application layer, using ZigBee, Modbus, MQTT and other protocols, which fully reflects the characteristics of the Internet of things (IoT) and mobile Internet, and meets the students’ mastery of mobile Internet knowledge. Through the design of 21 experimental projects, it meets the students’ mastery of mobile Internet knowledge, and can also meet the requirements of on-line teaching when COVID-19 is popular. The system practice shows that compared with before the platform is implemented, it improves the teaching level of students’ mastery of mobile Internet technology, and achieves a good purpose of experimental teaching.</p> <p> </p>
