The invention discloses an internet and thermal power plant heat production operation integrated management platform. The internet and thermal power plant heat production operation integrated management platform comprises a centralized dispatching control center, six important functional subsystems such as a heat and power generation optimized dispatching subsystem, a heat transmission and control subsystem, a pipe network safety management subsystem and the like, as well as long-distance pipe networks and user control terminals, wherein the user control terminals are accessed to the internet through a mobile communication network; the centralized dispatching control center and the functional subsystems are connected with each other through an industrial control network and connected with the internet; the heat and power generation optimized dispatching subsystem is connected with DCS of each generator set through the industrial control network; and the heat transmission and control subsystem is connected with each long-distance pipe network and each user control terminal through the internet and the mobile communication network. Through the internet and the private network, the heat production and operation businesses and the target requirements of the thermal power plants are integrated on one platform, so that the data share and business integration are realized, the production and operation efficiency is optimized, and the economic dispatching operation level and the enterprise management level are improved.

The invention provides a method for information extraction and identity authentication by identifying raster graphics. The method comprises the steps that the raster graphics are read, and obtained images are fed back; the fed-back images are automatically processed and placed in a cache; the images in the cache are analyzed and verified, so that code value information corresponding to the images is generated; information files corresponding to the code value information are found in a code value data base and extracted; the information files are decoded, so that multi-media files are formed, and the multi-media files correspond to the information files and comprise identity authentication information; the multi-media files are played, so that identity information of products corresponding to the raster graphics is obtained. According to the method, the raster graphics replace existing RFID labels and other modes, the method, the digital technique and the network technique are combined, and the method has the advantages of being low in printing cost, terminal manufacturing cost and enterprise operating cost, and achieving user inquiry mode convenience, and effectively achieves the effects of copying difficulty, low price and identifying convenience.
