Multi-source information interaction method for physical information system of energy Internet

Abstract

The invention relates to a multi-source information interaction method for a physical information system of energy Internet. A communication protocol is established between a server and a client, so that communication establishment between the server and the client is completed; when communication is carried out after the communication is established, the integrity of the data is guaranteed through a secondary handshake protocol; and communication between the components of the physical information system is realized through a publication and subscription mechanism. According to the method, thecost is greatly saved, and analog quantity data transmission which cannot be realized by independent wiring can be realized; remote maintenance and monitoring can be carried out through the Internet,and exchange, identification and control of data between devices, data between the device and the server, and data between the servers are realized; through the publication and subscription mechanism, all members in the physical information system can equally send and receive the information, and mutual interaction and communication can be realized.

Description

technical field [0001] The invention belongs to the technical field of electrical information, and in particular relates to a multi-source information interaction method of an energy internet physical information system. Background technique [0002] The Energy Internet is a new type of information-energy integration "wide area network" built on the concept of the Internet. It emphasizes the two-way on-demand of multiple energy sources such as power grids, oil and gas pipeline networks, gas networks, and heat networks with an open and peer-to-peer information-energy integration architecture. Transmission and dynamic balance use, so the interconnection of energy networks, the deep integration of Internet and Information Communications Technology (ICT) technology and energy systems are the key to the realization of Energy Internet. Such as figure 1 shown. [0003] It can be seen from the above that peer-to-peer openness, plug and play, wide distribution, two-way transmission...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above that peer-to-peer openness, plug and play, wide distribution, two-way transmission, and high intelligence will be important features of the Energy Internet. The system will spread across all links of the regional energy Internet. The energy Internet will include the communication and interaction of massive operating data composed of various energy sources such as cold, heat, electricity, and gas. Due to the types of information exchange protocols between each component unit and the energy network If the traditional centralized and hierarchical distributed communication methods are still used, it will be difficult to achieve flexible and effective information interaction between each component unit
