Embodiment Construction

[0029] figure 1 is a perspective view of elevator system 101 comprising elevator car 103 , counterweight 105 , tension member 107 , guide rail 109 , machine 111 , position reference system 113 , door 104 and system controller 115 . The elevator car 103 and the counterweight 105 are connected to each other by tension members 107 . Tension members 107 may comprise or be configured as, for example, ropes, steel cables, and / or coated steel belts. Counterweight 105 is configured to balance the load of elevator car 103 and is configured to facilitate movement of elevator car 103 within elevator shaft 117 and along guide rail 109 simultaneously and in opposite directions relative to counterweight 105 .

[0030] Tension member 107 engages machine 111 , which is part of the overhead structure of elevator system 101 . Machine 111 is configured to control movement between elevator car 103 and counterweight 105 . The position reference system 113 may be mounted on a fixed part at the t...

Abstract

A method for object detection within an elevator car including: transmitting radar signals at a selected polarization into an elevator car towards an individual; receiving reflected radar signals at areflected polarization ; comparing the reflected polarization to the selected polarization; determining that the individual is in possession of a metal object in response to comparing the reflected polarization to the selected polarization; and activating an alert in response to the determining that the individual is in possession of the metal object.

Description

technical field [0001] Embodiments herein relate to the field of elevator systems, and in particular to methods and apparatus for object detection in elevator systems. Background technique [0002] Elevator systems transport individuals to various points within a building, which can create potential safety risks depending on the security of the individual and the building. Contents of the invention [0003] According to an embodiment, a method for object detection within an elevator car is provided. The method comprises: transmitting a radar signal into the elevator car towards the individual with a selected polarization; receiving the reflected radar signal with the reflected polarization; comparing the reflected polarization with the selected polarization; responding to comparing the reflected polarization to the selected polarization to determine that the individual is in possession of a metallic object; and activating an alarm in response to determining that the indiv...
