The invention belongs to the technical field of information, and provides an industrial Internet information exchange method for improving heterogeneous industrial network intercommunication capability and promoting cross-protocol intercommunication of industrial equipment. On one hand, cross-system interoperation is realized by developing a heterogeneous network information interoperation standard and establishing a multi-level network information model system, integration of an information technology network and a production control network is promoted, and a specification standard is formed by using a semantic description means and a forced grammar data structure requirement under language environments used in respective technical fields. On the other hand, guidance and specifications are provided for the industry by constructing a semantic information exchange model, industrial development of industrial internet information exchange is promoted, and an information interaction model containing enterprise total factor, total value chain and total industry chain data is formed in an industrial internet ecological environment, and the problems that multi-source heterogeneous systems of an edge layer, an enterprise layer and an industrial chain layer are different, and data sharing services are difficult to integrate, so that information is blocked, unsmooth or inaccurate are solved.
