This article aims to design a comprehensive course experiment aimed at improving students’ knowledge mastery in an intuitive and interesting way, in response to the characteristic of limited class hours in the course “Computer Network” for automation majors. This experiment uses three laptops and a Raspberry Pi smart car to establish a WiFi wireless local area network. The program written in the laptop is transmitted to the Raspberry Pi car through the wireless local area network, and then the car is remotely controlled to compile the program. Afterwards, the application software in the laptop can view real-time video information collected by the camera of the Raspberry Pi car and control the movement of the car. The experiment principle part introduces the process of realizing wireless data communication based on the computer network architecture, highlights the CSMA/CA protocol used in the data link layer of wireless devices, and lists the key points of CSMA/CA protocol. This experiment can help students form a holistic concept of the knowledge of “Computer Network” and cultivate their ability to continue learning through the relevant technologies involved in the experiment.
