Core Strengths

The safety supervision plan for underground personnel is based on "3D facial recognition technology" as the core, combined with personnel positioning system, to achieve accurate verification of underground personnel identity, duty control and closed-loop management of hidden dangers. The plan aims to address the pain points of complex underground environment, shift fraud, and difficulty in tracing hidden dangers in coal mines. Through non-contact biometric technology, it ensures the authenticity of personnel on duty, on-site verification in high-risk areas, and real-time data synchronization, thereby improving the level of mine safety production. The plan aims to promote the transformation from "post accountability" to "pre prevention", in line with the policy requirements of the National Mine Safety Supervision Bureau for the leadership shift system.

Solution for Safety Supervision of Underground Personnel

Solution Architecture

The solution adopts a "end-to-end cloud" collaborative architecture to achieve closed-loop management of the entire underground process

End side equipment: Deploy intrinsic safety explosion-proof 3D facial recognition equipment in key areas underground (such as wellhead, working face, high-risk points) to verify personnel identity and record attendance. The equipment supports mixed deployment to fill the blind spots in underground supervision.

Side processing: The equipment integrates the function of network disconnection and transmission continuation, and interfaces with the personnel positioning platform to ensure automatic synchronization of data when the mine network is unstable.

Cloud platform management: The software platform centrally manages devices, personnel permissions, regional configuration, and data analysis, supports API integration with provincial regulatory platforms, and achieves intelligent warning and report export.

The scheme architecture emphasizes the linkage of "human machine environment": personnel identity is verified through 3D facial recognition, and the gate and sound and light alarm system are linked to provide real-time warnings for abnormal situations such as missed check-in and timeout check-in, forming a closed-loop process from admission detection, dynamic monitoring to hidden danger rectification.

Core Strengths

Compliance assurance

Comply with policies such as the "Regulations on Coal Mine Leaders Leading Work and Safety Supervision Inspection", provide complete logs and reports, and meet regulatory audit requirements.

System Integration

Support seamless integration with existing personnel positioning and warning platforms, break data silos, and achieve closed-loop management of hidden dangers (hidden danger registration → rectification assignment → on-site review → cancellation).
