This article takes practical engineering as a research case and systematically analyzes the problems existing in current safety supervision work. There are many high-risk work areas, and traditional inspection methods are difficult to detect hidden dangers in a timely manner. The definition of safety responsibilities between general contractors and subcontractors is vague, and relevant requirements are gradually attenuated during the execution process. The determination of risk and hidden dangers highly relies on personal experience and lacks reliable data support. There is a significant lag in emergency response, and the on-site disposal and command processes are disconnected from each other. In response to the above issues, the article proposes specific solutions, ultimately achieving real-time perception and warning of security risks, as well as effective coordination of emergency response.
