Discipline competitions can have a positive impact on the learning potential of students, as well as on their skills and innovation abilities. They are particularly effective in cultivating the engineering practice abilities of applied undergraduate students, which is of vital significance. This paper takes the Internet of Things (IoT) engineering major as an example to explore ways to cultivate the independent innovative consciousness, thinking, and skills of students, as well as to improve the overall quality of students. Key aspects such as the practice system of disciplinary competition, practice management and organisation strategy as well as the practice project development system are thoroughly researched and discussed, aiming to provide experiences that can be used and referred to for the cultivation of engineering talents.
