The invention relates to a real-time information acquisition method of a dynamic page of Internet of Things. The method includes four parts and relates to four modules which comprise a page loading module, a page access hypertext markup language (HTML) module, an analysis gaining HTML module and a data storage module. The page loading module loads an external page through a network link address and delivers the loaded dynamic page to the access HTML module. The HTML document of the page is obtained by the access HTML module and the obtained HTL document is delivered to the analysis HTML module which analyzes the needed text content from the obtained HTML document through a location technique and sends the text contents to the data storage module for storing. The real-time information acquisition method of the dynamic page of Internet of Things has the advantages that the real-time acquisition and the storage of the dynamic information of the Internet of Things entity are achieved and the connection with the data base on the server is unnecessary, the expandability is better, and the processing demands of the mass data size of the Internet of Things are met.
