Embodiment Construction
[0080] The core of the present invention is to provide a method and system for detecting the safety of industrial process control process flow, by respectively obtaining the data flow of the process control of the target industrial process control system and the real-time process control data flow, drawing the trend curve and real-time data flow of the safety monitoring point Trend curve: By comparing the trend curve of the safety monitoring point with the real-time trend curve, it can be judged whether the target industrial process control system is safe.
[0081] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0082] The embodiment of the present invention discloses a detection method for industrial process control process safety, see figure 1 , the detection method of industrial proc...

The invention discloses a method and system for detecting the safety of an industrial process control technological process, comprising: acquiring and analyzing a process control data flow of a target industrial process control system; extracting the state value of a safety monitoring point in the analyzed process control data flow and time stamp; according to the state value and time stamp of the safety monitoring point, the trend curve of the safety monitoring point is generated; the real-time process control data flow of the target industrial process control system is acquired and analyzed; the security information in the analyzed real-time process control data flow is extracted The state value and time stamp of the monitoring point; according to the state value and time stamp of the safety monitoring point in the real-time process control data flow, the trend curve of the real-time safety monitoring point is generated; the trend curve of the safety monitoring point is compared with the real-time safety monitoring point The trend curve is used to judge whether the target industrial process control system is in a safe state, and if not, an alarm will be issued. It realizes the in-depth inspection of the content of the process control interactive data flow combined with its specific control laws.
Description
technical field [0001] The invention relates to the technical field of industrial process control system safety, in particular to a method for detecting the safety of an industrial process control process flow and a system thereof. Background technique [0002] With the rapid development of my country's industrial modernization, the degree of industrial automation is getting higher and higher, and the industrial control system is becoming more and more perfect. [0003] Industrial process control systems are widely used in petrochemical, metallurgy, pharmaceutical and other important production fields. In recent years, with the development of informatization and networking of industrial control systems, information security has gradually become a new research topic in the field of industrial control. Functional safety, extended to network safety, and further extended to production process process safety. [0004] Process security has an important impact on the quality of p...
