Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of potential safety hazards identification, and in particular to a method and system for identifying potential safety hazards of lifting machinery based on AI. Background Art
[0002] The field of safety hazard technology involves safety identification, assessment and prevention strategies in various industrial and construction environments. In the application of lifting machinery, this field pays special attention to how to identify and deal with potential dangerous factors that may lead to accidents or damage. Technological development has led to the increasing application of artificial intelligence (AI) in this field, especially in the automated monitoring and prediction of safety hazards. AI technology can predict and warn of potential risks by analyzing historical accident data and real-time monitoring of equipment performance and environmental conditions, thereby improving work efficiency and safety.
[0003] Among them, the AI-based method for identifying safety hazards of lifting machinery refers to the use of artificial intelligence technology to identify and prevent safety problems that occur during the operation of lifting machinery. This method involves machine learning models and algorithms to analyze data collected from sensors, operation records, and environmental monitoring equipment. Through this technology, the operating status of lifting machinery can be monitored in real time, abnormal behavior or potential failures can be discovered in time, and preventive measures can be taken before accidents occur. It not only helps to ensure the safety of operators, but also effectively reduces economic losses caused by equipment failure or operating errors.
[0004] Existing safety hazard technologies rely on traditional data analysis and post-processing models, which can only react after an accident occurs, but lack preventive risk assessment and real-time monitoring. In a rapidly changing industrial environment, this model cannot effectively respond to sudden environmental changes and equipment status changes, resulting in delayed response time for safety warnings and increased risks of accidents. Insensitivity to changes in environmental factors causes lifting machinery to operate under inappropriate conditions, increasing the probability of safety accidents. The shortcomings of existing technologies in data integration and real-time analysis also affect the timeliness and accuracy of operational decisions, and cannot effectively prevent potential safety risks, resulting in unnecessary economic losses and safety hazards.
