According to an aspect, a method includes capturing image data from a video camera at a conveyance system. Analytics of the image data can be initiated to determine a plurality of conditions of the conveyance system. A status of the conditions can be summarized as a metadata output. The metadata output can be transmitted to a support system operable to initiate a corrective action responsive to the status of the conditions.

Conveyance system video analytics

An elevator system is provided. Aspects includes at least one elevator car and a camera affixed to the at least one elevator car, wherein the camera is operated by a controller. The controller is configured to automatically capture, from the camera, media associated with a set of locations, wherein the set of locations are associated with the at least one elevator car. A transceiver transmits one or more sequences of the media captured from the camera.

Elevator inspection using automated sequencing of camera presets

A method for automating maintenance of a conveyance system includes performing automated maintenance tasks on the conveyance system; storing results of the automated maintenance tasks in a maintenance database; and providing maintenance tasks to the mobile device, each maintenance task including a maintenance task identifier and a maintenance task status.

Automated conveyance system maintenance

Elevator systems having an elevator car within an elevator shaft are described. The systems include a plurality of landing doors located at respective landings within the elevator shaft with at least one landing positioning element installed within the elevator shaft and positioned relative to at least one landing door. An inspection system is configured with a detector located on the elevator car and arranged to detect the presence of the landing positioning element in an inspection region to determine if a position of the elevator car relative to the landing door is within a predetermined range.

Coded elevator inspection and positioning systems and methods

Elevator systems and methods for inspection having an elevator car within an elevator shaft are described. A plurality of landing doors are located at respective landings within the elevator shaft and a landing door gib is located on one of the landing doors and subject to inspection. The landing door gib includes an indicator element thereon, and an inspection system is arranged with a detector located on an exterior of the elevator car and arranged to detect the presence of the indicator element in an inspection region.

Imaging inspection systems and methods for elevator landing doors

A system continuously drives a motor during normal and power failure operating conditions. A regenerative drive delivers power to the motor from a main power supply during the normal operating condition and from a backup power supply during the power failure operating condition. A controller operates the regenerative drive to provide available power on the regenerative drive to the backup power supply during the normal operating condition.

System and method for operating a motor during normal and power failure conditions

A system () continuously drives an elevator hoist motor () during normal and power failure operating conditions. A regenerative drive () delivers power to the hoist motor () from a main power supply () during the normal operating condition and from a backup power supply () during the power failure operating condition. A controller () operates the regenerative drive () to provide available power on the regenerative drive () to the backup power supply () during the normal operating condition.

Elevator regenerative drive with automatic rescue operation

A hoist motor () for an elevator () is continuously driven from an irregular power supply (). A regenerative drive () delivers power between the power supply () and the hoist motor (). A controller () measures a power supply voltage in response to a detected change in the power supply voltage and controls the regenerative drive () to adjust a nominal motion profile of the elevator () in proportion with an adjustment ratio of the measured power supply voltage to a normal power supply voltage.
