An elevator management system includes an elevator system and a service provider controller. The elevator system is configured to control at least one elevator car and to transmit a status message indicating status data of the at least one elevator car. The service provider controller is configured to determine a current operating mode of the at least one elevator car based on the status message and to assign the at least one elevator car to a current status group among a plurality of different status groups based on the current operating mode.

Method for understanding and planning elevator use

A method for determining an elevator landing table from within an elevator car includes obtaining landing index information from a position indicator of an elevator with a landing identification system mounted within the elevator; communicating the landing index information from the position indicator via the landing identification system; and associating the landing index information to a building landing reference to determine a position of the elevator car.

Landing identification system to determine a building landing reference for an elevator

An elevator system is described. Aspects include an elevator shaft, an elevator car, and at least one camera, wherein the camera is operated by a controller. The controller configured to receive a maintenance request associated with the elevator system. The maintenance request is analyzed to determine an operational mode for the elevator car. The operational mode is enabled for the elevator car. The camera captures media associated with the elevator system responsive to enabling the operational mode for the elevator car.

Elevator auto-positioning for validating maintenance

An illustrative example method of determining a condition of an elevator car operating panel includes controlling a plurality of light sources of the car operating panel to turn on all of the light sources. An image of the car operating panel is obtained that indicates an actual illumination of all of the light sources, respectively. A determination is made, based on the obtained image, if there are any differences between an expected illumination and the actual illumination of any of the light sources. An indication of the condition of the elevator car operating panel is provided that includes information regarding any determined differences between the expected illumination and the actual illumination.

Method and system for detecting elevator car operating panel condition

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 method and system for remote access to multiple subsystems () of an elevator control system () are provided. The method includes receiving a request to establish a remote connection at an elevator control subsystem () from a remote user system (). The method also includes determining whether a local connection is established between the elevator control subsystem () and service equipment (). The method further includes establishing the remote connection in response to determining that the local connection is not established between the elevator control subsystem () and the service equipment (). The method additionally includes sending a time since the service equipment () was last active and providing an option to complete the remote connection in response to determining that the local connection is established, the elevator control subsystem () is operating in a first mode of operation, and a configurable local activity timeout period has not expired.

Remote access of an elevator control system with multiple subsystems

An elevator system () includes a propulsion power assembly () with a power rating below that required to move a fully loaded elevator car () using a contract or design motion profile. One example propulsion power assembly () uses more than one motion profile based upon existing load conditions. One example uses a first motion profile including a first power parameter limit for load conditions at or below a selected load threshold that is less than a maximum load capacity of the car (). The propulsion power assembly () uses a second motion profile with a lower power parameter limit for other load conditions. In one example, electrical current is the power parameter selected as a decision parameter dictating which profile to select based on an existing load. Another example propulsion power assembly () selects at least one of a speed limit or an electrical current limit based on an existing load and maintains a speed to stay within the selected limit.

Elevator motion profile control for limiting power consumption

A normal terminal stopping device (NTSD) using terminal zone position checkpoint detection with a binary coding method to identify a checkpoint within a terminal zone, and a digital shaft encoder mounted on the shaft of the hoist motor to determine a car position relative to a target stopping point. A microprocessor-based controller is used to compare a velocity command signal to a velocity limit reference. If the velocity command exceeds the velocity limit, the NTSD functions will take over to cause the elevator car to decelerate at the NTSD rate. In particular, the velocity limit reference is computed according to lead compensation and curve shaping techniques to attain better drive tracking characteristics of the motion controller. Binary coded checkpoints are used to eliminate error introduced in a car position derived from a motor shaft digital encoder. The normal terminal stopping device and method according to the present invention is less sensitive to the vane spacing as compared to the conventional NTSD designs.
