Problems solved by technology

However, the system needs to pre-train the risk assessment model when performing risk assessment. In practical applications, it is difficult to obtain a general model due to the changing usage of lifting equipment.
When the equipment situation changes, the model needs to be retrained, the real-time performance is poor, and dynamic risk assessment cannot be realized

Abstract

The invention provides a dynamic risk assessment method and device for hoisting equipment based on real-time data. The method comprises the following steps: acquiring operation data of the hoisting equipment for indicating a potential safety hazard event in real time; based on the real-time operation data, the operation parameter alarm limit value, the preset rated service life of the whole equipment and the part and the time heat coefficient of the alarm record, the occurrence frequency of the safety risk hidden danger event is calculated; based on the corresponding relation between the safety risk hidden danger event and each equipment risk and the occurrence frequency and the risk contribution degree of the related safety risk hidden danger event, calculating the possibility that each equipment risk causes an accident; obtaining a hazard degree coefficient of each equipment risk based on the hazard degree index of each equipment risk and the corresponding weight, and calculating an accident hazard degree index of each equipment risk based on the severity degree of each equipment risk and the hazard degree coefficient; and obtaining a risk assessment result of the hoisting equipment based on the accident hazard degree index and the possibility of accidents caused by various equipment risks.

Description

technical field [0001] The invention relates to the technical field of safety monitoring and management of hoisting equipment, in particular to a method, device and storage medium for dynamic risk assessment of hoisting equipment based on real-time data. Background technique [0002] Lifting equipment is a kind of electromechanical special equipment used to lift and carry heavy objects. It can greatly improve the work efficiency of the job site, so it is widely used in manufacturing, mining, construction and transportation. In recent years, the number of hoisting equipment in my country has shown a steady increase. However, due to improper use, equipment quality and safety defects, etc., safety accidents of hoisting equipment have occurred frequently, causing heavy losses to the lives and property of the people. [0003] At present, the safety management of lifting equipment mainly relies on manual spot inspection and regular inspection, and online monitoring and management ...
