According to the insufficiency of information sharing for many interfaces of EPC system and sensor system, IOT was analyzed by a kind of structure information for entity. The information of entity was divided into two: attribute- information and time-information. Within the information structure, a model of dynamic multi-dimensional information for IOT was proposed. EPC system was improved by this model and a new kind of architecture system for IOT was proposed to be used for information sharing. At last the new kind of architecture system for IOT was explained by a case of a container system.
