Problems solved by technology
At present, most devices have an operation training system, which pays more attention to the operator's proficiency in starting, stopping, and production operations, and ignores the training of the operator's emergency response ability to deal with abnormal conditions; the operating procedures only include the handling of a few accidents or abnormal conditions measures; most installations do not have a complete safety production training and examination system

Embodiment Construction
[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings and preferred embodiments.
[0050] see figure 1 Shown is the flow chart of the auxiliary decision-making method for accident prevention of petrochemical plant.
[0051] First of all, it is necessary to form an analysis group by experts in different fields (including design, manufacturing, installation, technology, equipment, instrumentation, environment, maintenance, etc.), and prepare to hold an analysis and discussion meeting.
[0052] Step 101, according to the design process package, put forward safety issues that may occur and need to be paid attention to one by one, including important design, manufacture, installation and other safety information and safety inspection items of equipment and unit operations, and equipment and unit operations in actual production. Safety information and safety inspection items for important operations and maintenance of u...

An accident preventing assistant decision-making method and system for a petrochemical unit are disclosed. The system comprises a safety information table and a safety examination table generation module (201), a danger and operability analysis module (202), an accident tree analysis module (203), an event tree analysis module (204), a knowledge storage module (205) and a display module (206), and further may comprise a training and learning submodule (207), an examination submodule (208) and an auxiliary decision-making submodule (209). With the method and the system disclosed in the invention, the accident occurrence probability is greatly decreased or the order of severity of the results caused by accidents is greatly reduced.
Description
technical field [0001] The invention relates to an accident prevention auxiliary decision-making method and system, in particular to an accident prevention auxiliary decision-making method and system for petrochemical equipment. [0002] Background technique [0003] To ensure the production safety of petrochemical installations, in addition to improving the robustness of the production process through intrinsically safe design, on the one hand, accidents must be prevented, and potential hazards should be found as comprehensively as possible through process hazard identification methods, so as to nip accidents in the bud; on the other hand, in When accident symptoms appear, abnormal conditions can be restored to normal through regulation, or risks can be reduced by enabling safety instrumented systems. [0004] Process hazard analysis methods commonly used in petrochemical plants include safety checklists, hazard and operability analysis, fault tree, event tree, and protect...
