Abstract:

In view of the problems that the traditional single-chip microcomputer experiment can only see the experimental results through the hardware circuit board in a fixed place, and the experimental data cannot be reproduced and analyzed, a set of innovative single-chip microcomputer experiment system based on the Internet of Things is designed in the proposed study. The system consists of Internet of Things experimental platform, experimental server and experimental board. The experimental platform uses STM32F205 chip to process and display the data of the experimental board, and uses NB-IoT technology to upload the data. The experimental server is based on B/S architecture and built on Alibaba Cloud to realize the forwarding processing and reproduction of experimental data. The experimental board uses MSP430G2553 chip and sensor chip to realize data collection and communication. The system realizes the remote display of data by designing the function processing, communication protocol and interface of each part, so that students can analyze the historical data at any time, to better find out the problems in the experiment, and teachers can give guidance more conveniently.

Key words: Internet of Things, NB-IoT, STM32, MCU experiment, B/S architecture, cloud platform, communication protocol
