Problems solved by technology

However, in the actual production process, the consequences of accidents caused by hazards are closely related to the reserves and damage characteristics of hazards, and the number of hazards also changes with time. According to the existing classification method, once a major hazard is classified into At a certain level, there will be no change
This grading method is obviously not in line with the actual production situation

Embodiment Construction

[0051] A method for dynamic classification of major hazard sources of liquid chemicals in the storage tank area of ​​a petrochemical wharf according to the present invention will be further described below in conjunction with the accompanying drawings.

[0052] The design idea of ​​the present invention is to apply the idea of ​​dynamic classification to the classification of major hazard sources, and accurately reflect the relative risk relationship of various hazard sources when reserves change. The hierarchical calculation program of the present invention is realized on the LabVIEW virtual instrument platform. LabVIEW is an integrated program development environment based on "graphics". Built-in signal acquisition, measurement analysis and data display functions. It integrates development, debugging and operation. Different from other instrument platforms, LabVIEW adopts "graphical" language programming instead of textual language programming. LabVIEW is easy to program,...

Abstract

The invention discloses a method for dynamically grading major hazard sources of liquid chemicals in a storage tank region of a petrochemical wharf. The method comprises the following steps: creating an accident consequence model of the major hazard sources of the liquid chemicals in the storage tank region of the petrochemical wharf and calculating a major hazard source injury index; taking the major hazard source injury index as initial data for grading the major hazard sources and performing standardization calculation; initially grading the major hazard sources of the liquid chemicals; continuously adjusting the grades of all the hazard sources on the basis of initial grading by a cluster analysis principle and outputting a grading result until reasonable grading. The method has the effects of accurately reflecting a relative risk relationship among various hazard sources when the storage capacity is changed, effectively solving the current situations of simple and fixed grading standards of the major hazard sources and high subjectivity and generality of the grading result, guaranteeing the real-time variability of the grades of the major hazard sources, and setting protection grades corresponding to the conventional control measures and safety technical means of the production enterprises of the petrochemical wharf.

Description

technical field [0001] The invention relates to a LabVIEW virtual instrument grading system for major hazard sources of liquid chemicals in a storage tank area of ​​a petrochemical wharf, in particular to a method for dynamically grading major hazard sources of liquid chemicals in a storage tank area of ​​a petrochemical wharf. Background technique [0002] The classification of major hazards is an important means of controlling and managing major hazards. Whether the classification results are reliable and reasonable has an important impact on the supervision of major hazards and the arrangement of emergency forces. At present, there is no unified classification standard for the classification of major hazards in my country. According to international practice, the inherent risk of the unit is used as the basis for classification, and major hazards are divided into four categories according to the casualties and property damage caused by accident consequences. class. Howeve...
