‌The personnel approach warning and protection system (PAWPS) is an advanced safety monitoring technology mainly used in high-risk environments such as industry and mining to reduce accidents caused by personnel approaching hazardous areas or moving equipment. The system can automatically detect the proximity of personnel to hazardous areas or equipment, provide automatic warnings, and intervene urgently. Key components include sensors, cameras, communication equipment, alarm devices, and operating systems. This system has the characteristics of high-precision positioning, fast response, and intelligent analysis, providing multiple protections for the safety of underground personnel, reducing accidents, and improving operational efficiency.
