Major hazard recognition method, major hazard recognition system, storage medium and computer device

Abstract

The invention relates to a major hazard recognition method, a major hazard recognition system, a storage medium and a computer device. The method comprises steps: the state information of a hazard is acquired; the state information is inputted to a pre-built accident evolution model, and an accident type evolved by the hazard and the happening possibility of each accident type are obtained; according to the preset criterions, a disaster bearing carrier corresponding to the hazard is determined, and an exposure assessment model and a vulnerability assessment model of the disaster bearing carrier are acquired, wherein the number of preset criterions is at least two; the output result of the accident evolution model is read, and according to the output result, the exposure assessment model and the vulnerability assessment model, a risk prediction value corresponding to each criterion is calculated; and the risk prediction value of each preset criterion is compared with a corresponding risk threshold, and according to the comparison result, whether the hazard is a major hazard is judged. Thus, the major hazard can be effectively recognized, and happening of a major accident is prevented.

Description

Technical field [0001] The invention relates to the technical field of risk assessment, in particular to a method, system, storage medium and computer equipment for identifying major hazards. Background technique [0002] Safety and danger are two relative states. The so-called safety is a state in which the risk of injury or damage is limited to an acceptable level; otherwise, it is dangerous, and major danger refers to the danger exceeding the set acceptable range status. Any system changes in motion, so usually the hazard of the hazard source also varies with the change of the system state. [0003] At present, the identification methods of hazard sources are evaluated based on the inherent characteristics of the hazard sources. For example, the identification of chemical hazards is based on the assessment of the inherent characteristics of chemicals, and the hazard of nuclear radiation hazards is based on their inherent radiation strength. Evaluation: The results of this eval...

Problems solved by technology

[0003] At present, the identification methods of hazards are all evaluated based on the inherent characteristics of the hazards themselves. For example, the identification of chemical hazards is based on the evaluation of the inherent characteristics of chemicals, and the danger of nuclear radiation hazards is based on their inherent radiation strength. evaluation; the referenceability of this evaluation result is weak, and it is difficult to effectively avoid the occurrence of major dangerous accidents
