With the development of the Internet of Things (IoT), a flood of information is mappinginto the information space from the physical space, which is bound to cause the informationspace of the reconstruction. Because network convergence depends on the application andcontrol of information, the research on integration of physical space and information spacewould be main content of the IoT architecture system.Various of entities constitute physicalworld, which has space-time structure, with its own scale-dimensionality of features todescribe.At present, the information of the physical world exist uncertainty, unpredictability andambiguity, but the existing mapping model, theory and tools can not be achieved, so theinformation of Internet of Things can cause distortion and dishonesty issues. In the physicalspace and the information space, how to build a description of temporal and spatial variationsvariation, and the abstract in constraints, has been the theoretical foundation of the Internet ofThings architecture, as well the operating mechanism can make the abstract description ofinformation world truly map to the physical world.Faced with the perception, interaction, virtual-real integration, structural isomerism,complexity and other features of the Internet of Things, this paper proposes a research ofentity in the physical space and the information space. At first, this thesis briefly introducesthe development status, the structure system and key technologies of the Internet of Things,then conclude the personality characteristics of the physical entities; propose a mathematicaldescription based on the function relation between entities and conceptual entity; build therelational madel of entities in different information space. Meanwhile, the article analyzes thetime-space dynamic characteristics of mapping in the physical space and cyberspace, in orderto build the time-space mapping model. Entity realizes information mapping in in timespindle, which can measure the trajectory and life cycle of information in the physical spaceand cyberspace.Based on general information theory, this paper discusses four concept space and their relationships, and then tentatively constructs the mapping model of entity information in thelimited physical space. In order to reduce the information distortion in the Internet of Thingsand ensure the intergrity, historical and effectiveness, this paper also establishes themathematical relationship of information mapping between physical space and cyberspace.The research of information mapping method in the background of the Internet of Things,which provides a possible way to study the integration of the virtual information space andthe reality physical space.
