Abstract: The development of Internet of Things has been changed our styles from working, studying and living. It also provides a new form for the experimental teaching in the universities.. This paper aims at studying the open experimental teaching of intelligent laboratory system, taking the basic experiment management process as the core, including the function of experimental course scheduling, entrance controlling and attendance management, device management, computer management, laboratory monitoring and management. The system is constructed with browser-server architecture and establishes an open management platform for teachers, students and laboratory administrators, and so on. The system is built by using the server browser model, which can break the time and space constraints. Then the teachers and students of the interactive network on the open management platform can achieve the experimental administrator. It is proved that the intelligent laboratory system based on the Internet of Things technology can give full play to the advantages of the new technology, provide a convenient and efficient management way for the practice teaching, greatly reduce the burden of the experiment manager and improve the work efficiency and effect of the teachers.
