Abstract

The invention discloses a safety management method based on dynamic quantitative accident risk prediction, and the method comprises the following steps: an accident predicting platform is provided, and a basic event dynamic predicting model and an accident analyzing model are established; the accident predicting platform detects state information of production units in real time, and failure information is obtained; then the basic event dynamic predicting model predicts the failure information to obtain basic event dynamic probability; then the accident analyzing model calculates the basic event dynamic probability to obtain the current accident risk probability of the production unit; then the current accident risk probability and a preset risk probability control criterion are compared, if the accident risk probability is more than the risk probability control criterion, a preset emergency plan is started to assist an executor to tackle the accident; if not, a preset standard working flow is started, and a warning message is emitted so that the executor can correct a mistake. The method and the system can reflect the influence of dangerous factor change on probability dangers in real time, thus really realizing the safety management idea of prevention first.

Description

technical field [0001] The invention relates to the field of production safety, in particular to a dynamic quantitative-based accident prediction safety management method and system. Background technique [0002] Production safety is an essential cornerstone for protecting people's lives and property, promoting economic development, and building a harmonious society. With the development of industry, the expansion of production scale, and the increasingly complex technology, the risk of accidents has also increased. The traditional safety management model that focuses on the post-event treatment cannot meet the needs of development and has gradually been replaced by the "prevention-oriented" safety management. Pattern substitution. The fundamental method of the "prevention first" safety management model is to analyze the possible accidents qualitatively or quantitatively in each management stage according to the principle of the cause of the accident, combined with their sp...
