Abstract
An elevator system includes an elevator car within an elevator hoistway; a camera; a network; and an image analysis system in communication with the camera over the network; the camera providing a reference image to the image analysis system; the camera providing a current image to the image analysis system; the image analysis system comparing the current image to the reference image to detect a difference between the current image to the reference image; the image analysis system initiating a maintenance notification to a user device in response to the comparing.
Claims23
An elevator system comprising:
- an elevator car within an elevator hoistway;
- a camera;
- a network;
- and
- an image analysis system in communication with the camera over the network;
- the camera providing a reference image to the image analysis system;
- the camera providing a current image to the image analysis system;
- the image analysis system comparing the current image to the reference image to detect a difference between the current image to the reference image;
- the image analysis system initiating a maintenance notification to a user device in response to the comparing;
- wherein the maintenance notification includes the current image;
- wherein the current image in the maintenance notification is highlighted with an indicator of a difference between the current image and the reference image.
A method for determining that maintenance is needed in an elevator system, the method comprising:
- providing a reference image of the elevator system;
- providing a current image of the elevator system;
- comparing the current image to the reference image to detect a difference between the current image to the reference image;
- and
- initiating a maintenance notification to a user device in response to the comparing;
- wherein the maintenance notification includes the current image;
- wherein the current image in the maintenance notification is highlighted with an indicator of a difference between the current image and the reference image.
