Operation management and control system safety risk grade evaluation method based on information fusion

Abstract

The invention discloses an operation management and control system safety risk grade evaluation method based on information fusion, and the method comprises the steps: dividing each pre-evaluation point for pre-evaluation, and determining the risk value of each type of pre-evaluation according to each pre-evaluation point; establishing a pre-evaluation matrix for pre-evaluation, and calculating the weight of each type of pre-evaluation according to the pre-evaluation matrix; according to the pre-evaluated risk value of each class and the pre-evaluated weight of the corresponding class, obtaining a pre-evaluated risk score; dividing each real-time evaluation point of real-time evaluation, and determining a danger value of each type of real-time evaluation; establishing a real-time evaluation matrix for implementing evaluation, and calculating the weight of each type of real-time evaluation; obtaining a risk score of real-time evaluation; obtaining a personal total risk score and a personal total risk degree; and determining the safety risk level of the personal operation according to the personal total risk score and the personal total risk degree. According to the invention, the safety risk level of the operator can be evaluated more comprehensively and reasonably.

Description

technical field [0001] The invention belongs to the technical field of fusion of information technology and safety production, and in particular relates to a safety risk level assessment method for an operation management and control system based on information fusion. Background technique [0002] Risk management and control of electric power operation safety has always been one of the focus of work in the electric power industry. At the operation level, documents such as "Standards for Classification of Electric Power Operation Safety Risks" and "Standardized Work Specifications for Safety Control of Production Operations" have been formed. Regulations and norms cannot accurately judge dangerous situations based on the conditions of the job site. [0003] Among the operable methods of risk assessment, there are also expert scoring and evaluation methods, operating condition hazard assessment methods, and probabilistic hazard assessment methods. Among them, the expert scor...

Among them, the expert scoring and evaluation method is a reference opinion given by the expert group to analyze the source of danger and the degree of harm. The disadvantage is that it belongs to the pre-judgment of the risk situation and cannot be judged in real time according to the on-site situation.

The risk assessment of operating conditions is based on the overall score of three dimensions: the risk of accidents, the frequency of human exposure to dangerous environments, and the possible consequences of accidents. The higher the score, the greater the risk. The disadvantage lies in its risk. The higher the factor, the higher the score, there is no upper limit, and the judgment of danger is still relatively rough, and it does not have the ability to judge the situation on the spot

The probabilistic risk assessment method is a relatively systematic evaluation method through comprehensive analysis of the probability of accidents occurring in each operation unit. It can perform quantitative analysis to the greatest extent, but the disadvantage is that it pays more attention to the accident unit, and the degree of integration of other relevant factors such as operation information is not high
