Science experiment teaching system based on Internet of Things and work method thereof

Abstract

The invention provides a science experiment teaching system based on the Internet of Things. The science experiment teaching system comprises an Internet of Things sensing unit, an Internet of Things routing unit and an Internet of Things server unit. The Internet of Things sensing unit is used for measuring to-be-measured variables in the experiment process in real time, and converting measured data into data frames to be sent to the Internet of Things routing unit. The Internet of Things routing unit is used for receiving the data frames sent by the Internet of Things sensing unit and converting the data frames into data commands to be sent to the Internet of Things server unit. The Internet of Things server unit comprises a network database and a software program, and the network database is used for storing data in the data commands. The software program is used for carrying out real-time inquiring, analysis, screening, graphic display and experiment report filling on data in the network database. The science experiment teaching system is based on the Internet of Things, multi-user access is supported, the limitation of time and geographic positions is avoided, computing resources can be allocated elastically, and the advantages of being accurate in measurement, efficient in data transmission and the like are achieved.

Description

technical field [0001] The invention relates to the application field of experimental teaching, in particular to a science experimental teaching system based on the Internet of Things and a working method thereof. Background technique [0002] The Internet of Things is a network that uses a new generation of information technology to connect sensors and other items to the Internet for information exchange and communication to achieve intelligent identification, positioning, tracking, monitoring and management. The Internet of Things is also known as the third wave of the development of the world's information industry after computers and the Internet. Liu Jia, Liu Boquan, Song Tiecheng, Shen Lianfeng used RFID tag technology to design and develop intelligent logistics and intelligent medical care applications in the paper "Design and Implementation of an Internet of Things Teaching Experiment System" published in "Journal of Electrical and Electronic Teaching" in December 20...

AI Technical Summary

Problems solved by technology

However, this experimental system cannot collect and obtain experimental data from the real world. All operations are completed in software, and it does not have the architecture system of the Internet of Things. It cannot provide learners with real and effective science experiment teaching services.
