Abstract: Industrial Internet enables the interconnection of everything including human,environment and machines.To solve the complex problem of safety and reliability of industrial interconnected system,a loosely coupled architecture was proposed.Adopting publish/subscribe model and quality of service of multiple modes,connecting and processing of the multi-dimensional data in real time was achieved.Based on the strength of industrial elements and the centrality of information entropy,a Strength-Entropy Centrality (SEC) evaluation algorithm named compound centrality algorithm was constructed to calculate the vulnerability and key points of the loosely coupled system.The experiment results showed that the proposed SEC evaluation algorithm could accurately measure the key points of industrial interconnected system,and the algorithm was employed to CIMS_LINK.System members were calculated and ranked according to the algorithm,and the state monitoring of key members was realized to ensure the stable operation of industrial interconnected system.
