Abstract-Facing the immature situation of the practice teaching system of IOT engineering in Colleges and Universities, The subject of this study is to propose a practice teaching system to perfect the current IOT engineering talent training mode to meet market demand. On the basis of analyzing the problems existing in the practical ability training and the industry consensus of the technology and course system, we designed and implemented an open practice teaching system of innovationoriented IOT engineering. The system consists of two types of roles and four modules. Our practice shows that the system can guarantee the efficient management of practice teaching, makes students and teachers pay more attention to how to improve the efficiency of realization of students' practical ability, and can effectively meet the individual needs of students to improve the learning initiative. It needs to be emphasized that this practice teaching system is a dynamic system, and it needs to adjust the corresponding modules with the changes of technical system and market demand.
