Embodiment Construction

[0045] The implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection of the present invention are not limited thereto.

[0046] Such as Figure 1a, is a schematic diagram before the processing of domino effect discrete islands in the implementation mode. There are a large number of relatively independent hazard source units in the chemical industry park. picture. The nodes connected by the accident domino effect in the chemical industry park represent the hazard source units, and the connecting lines between the nodes represent the mutual influence between the hazard sources of the two nodes.

[0047] A hazard unit in a chemical industrial park can form a certain range of influence after an accident. When there are other hazard units within the range of influence, it may cause damage to the hazard unit and induce a secondary accident. Accidents may occur in the affected secondary...

Abstract

The invention discloses a discrete island processing method for the domino effect of accidents in a chemical industrial park. On the basis of the expansion rule of the accident domino effect, an accident chain is cut off through necessary technical intervention so as to avoid unceasing expansion of the accidents. The method comprises the following steps: firstly, setting an objective function for discrete island analysis and determining the final objective of the discrete island analysis; then designing an index for representing the accident expansion capability of dangerous sources so as to analyze the closeness of interaction among accident dangerous source units and find out the most important dangerous source in the accident expansion process; and finally taking an adjustment or control enhancement measure for the important dangerous source unit so as to achieve discrete island analysis on the domino effect of the accidents in the chemical industrial park. The discrete island processing method can avoid domino effect of the accidents in the chemical industrial park in the essentially safe aspect.

Description

technical field [0001] The invention relates to public safety predictive control technology, in particular to a method for processing discrete islands of domino effect accidents in chemical industry parks. Background technique [0002] European countries and most developed countries in the world have carried out accident domino effect related research. At present, domestic and foreign researches on the accident domino effect mainly focus on the following aspects: [0003] 1) Criterion of target unit vulnerability critical quantity [0004] The accident domino effect first needs to establish the conditions for judging the accident of the target unit. The target unit vulnerability critical quantity criterion is the parameter critical quantity to judge whether the accident expansion occurs. Once the accident expansion parameter at the target unit reaches the critical quantity, the secondary accident is considered to occur. [0005] 2) Domino Effect Empirical Probability Anal...
