The safety and health status of on-site personnel during the construction process has become a routine task for enterprises and organizations. However, the health management of personnel faces an extremely heavy workload. Currently, the management system for on-site personnel at construction projects is still at the stage of facial recognition and real-name registration, making it difficult to achieve normalized health management for construction site personnel. In response to this, this article constructs an intelligent prevention and control measurement and reporting system for construction sites during sudden public health emergencies. This system includes functions such as automated data collection, data circulation and integration, statistical analysis of measurement and reporting data, and intelligent control, achieving the intelligent management of health prevention and control on construction sites during sudden public health emergencies. The system has been validated in practical projects and has achieved effective results.
