Scenario
Application scenario
Overhead-crane positioning and obstacle avoidance need a stable target, clear path, and known coordinate reference. Distance supports travel and obstacle logic but does not replace limit switches, redundancy, or safety control.
Engineering problem
- Swing, vibration, and structural occlusion can change the measurement direction.
- Target size, angle, and surface affect long-range returns.
- Positioning, limit functions, and safety anti-collision need layered and redundant control.
Why LiDAR
Long-range LiDAR provides direct distance between equipment and a target for travel zones, slowdown points, and separation monitoring.
Workflow
- Define the measurement axis, target, maximum travel, and control safety zones.
- Design rigid mounting, vibration control, and an unobstructed path.
- Integrate distance and status into the PLC for travel, slowdown, and fault handling.
- Validate full travel, swing, dust, and worst expected lighting.
