The personnel proximity protection system adopts multi-source fusion technologies such as precise positioning, video monitoring, and radar detection. It includes functions such as one-dimensional multi-base station positioning, two-dimensional single-base station positioning, thermal imaging recognition, and AI-enhanced recognition, building an integrated perception system in complex environments. It can be used for active safety protection of large mobile equipment such as hydraulic supports and roadheaders in different underground mining environments. The system overcomes installation constraints, achieving real-time and accurate detection of personnel on workfaces, hazard area division, graded warning settings, bidirectional alarms, automatic locking, and special personnel access management. It fundamentally ensures the safety of personnel on workfaces and significantly enhances the level of intelligent mining underground.
