The application of the Internet of things greatly promotes the development of social productivity and changes the social life style of people.
Because different manufacturers provide respective development platforms and hardware of the internet of things at present, and tool chains of applications of the internet of things, hardware platforms of equipment of the internet of things and specific manufacturers are tightly coupled, the manufacturers of the existing internet of things systems are suppliers of a whole industrial chain (from the equipment of the internet of things to intermediate system integration until application of a client), and data sharing, networking and communication between the equipment of the internet of things and the equipment of the internet of things across platforms and local area networks are difficult to realize. Besides a few mature fields, the development of the Internet of things presents the characteristics of application fragmentation, system complexity, deep customization and the like, the large-scale development of the application is limited, and the Internet application solution for the Internet of things has the problems of complexity, diversity, bloat and the like. The Internet of things mode based on the protocols and the closed solutions of different manufacturers enables the good situation of the Internet of things in practical application to be limited in the industry, and scale development and innovation are difficult to realize. The internet of things industry urgently needs to solve the problems, and on the basis of the existing mature technology of the internet of things and the internet, the research of a common support platform and a core technology of a system layer is implemented, so that the industry barrier is broken through in a new mode.
The research on the plug-and-play driving method for accessing the internet by the internet of things device is one of key technologies for realizing independence of the internet of things application program and the internet of things device, and is also one of important support technologies for supporting an internet of things industry chain to realize loose coupling among manufacturers of the internet of things device, providers of a system integration platform and distributors of the internet of things application program. The research in the aspect is mainly to design the interface specification and the example of the driver program facing the application end and to establish a driving mechanism facing the internet of things equipment.
