Description

Technical Field

[0001] The present invention relates to the technical field of safety management, and in particular to a smart construction site area construction personnel safety work management system and method. Background Art

[0002] Modern construction sites have complex environments and a large number of people. Traditional safety supervision methods are difficult to achieve real-time and comprehensive monitoring, which can easily lead to safety hazards not being discovered in time. In recent years, although some construction sites have introduced video surveillance and basic Internet of Things technologies, they lack effective intelligent analysis methods and cannot automatically identify unsafe behaviors, and the early warning efficiency and accuracy are limited. The defects or shortcomings of existing technologies in the field of smart construction site personnel safety management are mainly reflected in the following aspects:

[0003] Monitoring limitations: Traditional video surveillance systems usually rely on manual monitoring, which is not only inefficient, but also prone to missing important security events due to human negligence. Even if some systems have detection functions, they often generate a large number of false alarms due to low recognition accuracy and cannot accurately distinguish between normal operations and unsafe behaviors.

[0004] Lack of intelligent analysis: In existing technologies, the judgment of personnel safety behavior mostly relies on rule presets and simple logical judgments, and lacks the ability to understand complex scenarios. This makes it difficult for the system to identify unsafe behaviors such as not wearing safety equipment correctly and operating heavy machinery in violation of regulations, and it is also unable to dynamically adjust safety standards according to environmental changes.

[0005] Early warning lag and passive response: Existing systems often trigger alarms only after an accident occurs, lacking an effective early warning mechanism. Even if there is an early warning, it is usually a simple judgment based on a fixed threshold, and cannot intelligently predict risks based on historical data and real-time situations, making it difficult to achieve active prevention.

[0006] Lack of personalized management and continuous optimization: For individual worker safety education and performance evaluation, the existing management system often adopts a one-size-fits-all approach, lacking targeted training and incentives. At the same time, the system itself lacks self-learning and optimization mechanisms, making it difficult to dynamically adjust the algorithm model according to actual conditions and improve the accuracy of identification and early warning.

[0007] User experience and operational complexity: Many existing systems have unfriendly interfaces and are complex to operate, making them difficult for frontline managers and workers with limited technical skills to quickly understand and use, which affects the popularization of the system and the maximization of its utility.
