Patent No. EP3508445 (titled "Elevator Auto-Positioning For Validating Maintenance") was filed by Otis Elevator on Jan 4, 2019. The application was issued on Jul 12, 2023.
Elevator system for performing maintenance, comprising a controller, a transceiver, and a camera. The controller analyzes sensor data from the elevator system to determine maintenance requests. The transceiver transmits the sensor data to a maintenance server, which analyzes the data to identify root causes of anomalies. The server determines operational modes for the elevator car based on the root causes, including camera positions, car locations, and velocities. The camera captures images or video of the elevator system, which are transmitted to the server for further analysis.
