Challenges in Traditional Coal Flow Measurement
Conventional methods such as nuclear belt scales and electronic belt scales face significant challenges in modern mining environments:
- High safety risks: Nuclear detection relies on radioactive sources, which are strictly regulated and potentially hazardous.
- Low efficiency: Mechanical systems require frequent calibration, suffer from wear and drift, and are difficult to maintain.
- Environmental interference: Dust, vibration, and varying light conditions often lead to unstable or inaccurate measurements.
- High maintenance costs: Contact-based systems increase downtime and reduce productivity.
These issues make it difficult to achieve continuous, accurate, and safe coal flow monitoring, highlighting the need for a non-contact, intelligent, and reliable solution.

Goermicro ToF Camera Solution
To address these pain points, Goermicro introduces a coal flow detection solution powered by industrial-grade 3D Time-of-Flight (ToF) cameras. The NYX series, designed specifically for real-time coal flow monitoring, delivers superior performance through its core capabilities:
- High-precision measurement: Millimeter-level depth accuracy enables precise calculation of coal volume and flow rate.
- Wide field of view: Provides full coverage of conveyor belts, eliminating blind spots in monitoring.
- Robust light adaptability: Performs reliably under weak light, strong light, and heavy dust conditions.
- Multi-camera coexistence: Supports synchronized operation of multiple cameras for extended monitoring ranges.
- Industrial-grade durability: IP67-rated protection ensures resistance to dust, water, and vibration.

Working Principle
Goermicro’s ToF camera emits modulated infrared light and measures the time it takes for the reflected light to return, generating real-time 3D depth maps of the coal on the conveyor belt. Advanced algorithms analyze the surface shape of the coal layer, calculate its volume, and output instantaneous flow rate data in real time. The processed results are transmitted to the control center, enabling automated management, load balancing, and predictive maintenance.
This closed-loop process: Perception→Analysis→Optimization forms the core of intelligent coal flow monitoring.
