Research on the security of chemical Industry Automation system based on networked control
With the rapid development of computer technology and the in-depth application of Internet technology,the automa-tion system of chemical industry has evolved to the development direction of network and intelligence.However,the networked control system of chemical industry brings the improvement of production efficiency and the decrease of operating cost,but also brings the sig-nificant risk of system network security.In order to enhance the safety of the automation system in the chemical industry,this paper deeply studies the safety problems existing in the automation system of chemical industry based on the network control,and effectively solves them.Firstly,the existing network security threats and their sources of the chemical industry automation system are analysed,and then,a security protection model based on networked control is proposed,and the corresponding protection strategy is designed on the basis of this model.The results show that this security protection model and protection strategy can effectively prevent the automa-tion system of the chemical industry from the risks by external attacking,ensure the normal operation of the system,meanwhile im-prove the stability and reliability of the system.The results of this study are of great significance for improving the network security protection ability of chemical industry automation system and ensuring the safe and stable operation of chemical production process.
