Solution

LiDAR application solution for revolving-door safety sensing

Provide distance or presence input in critical revolving-door zones for controller slowdown, stop, and fault handling.

LiDAR sensing critical zones around a revolving door

Scenario

Application scenario

Revolving-door safety sensing must cover critical entry zones and coordinate with door position and motion. LiDAR supplies area distance input but does not replace the complete safety controller, redundancy, or regulatory validation.

Engineering problem

The moving leaves change the relationship between the sensing and hazard zones.
People, luggage, children, and low objects require coverage at different heights.
Strong light, glass reflections, contamination, and structural occlusion affect measurement.

Why LiDAR

A line-pattern LiDAR can provide near-field input across a narrow area for the controller to combine with door position.

Workflow

Define hazard zones, targets, door speed, and stopping distance.
Design coverage around the door structure and avoid glass or frame occlusion.
Integrate distance or area state into slowdown, stop, and fault logic.
Validate people, luggage, low objects, strong light, and contamination.

Technology comparison and selection

Dimension	Condition	LiDAR	Alternative	Alternative performance	Conclusion
Presence and distance in a narrow zone	Critical areas need continuous coverage while the door moves.	Provides near-field measurement across a line-pattern zone.	Safety light curtain or contact edge	Uses different coverage and certification paths and may perform a dedicated safety function.	LiDAR can be a door-controller input; statutory safety functions, redundancy, and certification remain system decisions.

Installation and integration

Mount from leaf motion and hazard zones, avoid frame, glass, and structural occlusion, and combine distance or area state with door position in the controller.

Operating limits

A sensor application page does not establish system safety certification. The revolving-door system must validate stopping distance, redundancy, fault handling, and regulatory compliance.

FAQ

Frequently asked questions

Can LiDAR replace the revolving-door safety system?

No. LiDAR is a distance or area input. Stop logic, redundancy, fault handling, and regulatory compliance remain responsibilities of the complete door safety system.
