HUMAN BODY SAFETY PROTECTION LASER SENSOR FOR REVOLVING DOOR

Document Type and Number:

WIPO Patent Application WO/2019/000937

Kind Code:

A1

Abstract:

Disclosed is a human body safety protection laser sensor for a revolving door. The laser sensor comprises: a laser scanning distance measurement part and an application analysis part. The laser scanning distance measurement part comprises: a laser emission apparatus, a laser deflection apparatus, an optical signal receiving apparatus and an analysis processing apparatus, wherein the laser emission apparatus emits a laser signal to the laser deflection apparatus; the laser deflection apparatus deflects the laser signal at a pre-set angle, and forms at least one laser scanning area; the optical signal receiving apparatus receives the returned laser signal, and transfers the signal to the analysis processing apparatus; and the analysis processing apparatus comprises: a trigger point distance analysis module, wherein according to a signal sent by the optical signal receiving apparatus, the module obtains distance information about a trigger point by means of analysis. The application analysis part comprises: a safety analysis module, wherein according to the distance information about the trigger point, the module controls a motion state of a revolving door by means of a door control apparatus after analysis.
