A method for dynamic elevator door control is provided. The method is implemented by a system, which includes an elevator. The system procures passenger data, which can include a number of passengers presently travelling to a floor and a number of passengers awaiting to board at the floor. A determination is made by the system with respect a door operational time based on the passenger data. The system implements the door operational time to dynamically cause doors providing access to the elevator to remain open for a duration of the door operational time.

Disclosed is an elevator system for a multilevel architectural structure, the system having: a system controller, an elevator and an elevator controller, wherein the system controller and elevator controller communicate over a network, multi-level hoistway in which the elevator travels, the multi-level hoistway including a plurality of egress levels, including a first egress level, the first level being a primary egress level, wherein during an alarm condition the system, when the primary level is inaccessible, performs an emergency assessment of identifying a safe level of the plurality of levels at which to discharge passengers, the assessment comprising obtaining a smoke density profile for the egress levels, the profile illustrating a distribution of smoke within the multilevel structure, analyzing the smoke density profile, identifying a safe level having a smoke density that is safe, and instructing the elevator to discharge passengers on the safe level.

A lift system for protecting the privacy of passengers. The lift system having a lift car that can be moved between floors of a building. The lift car having a video camera arranged in the lift car. The video camera being a part of a video system that also includes a video monitor for displaying information relating to the interior of the lift car. A video control device is communicatively connected to and controls the video system in a selective manner according to one of several operating modes. The several operating modes include a first operating mode in which the video system is deactivated or activation is blocked, so that the video system remains in an inactive state, if a passenger asks for the video system to be deactivated. When in the first operating mode the video system remains in the inactive state for as long as the passenger is in the lift car.

An elevator door monitoring system for monitoring movement of an elevator door (6, 16) includes an elevator door detector (30) including an RFID tag (32) configured for being attached to a first element (16a, 26a) of the elevator door (6, 16); and an RFID sensor (34) configured for being attached to a second element (16b, 26b) of the elevator door (6, 16), wherein the second element (16b, 26b) is movable with respect to the first element (16a, 26a). The elevator door detector (30) is configured for detecting a distance between the first and second elements (16a, 26a, 16b, 26b) of the elevator door (6, 16) and for supplying a corresponding detection signal. The elevator door monitoring system includes an evaluator (17) configured for receiving detection signals supplied by the elevator door detector (30) and for evaluating the received detection signals for detecting potential malfunctions of the elevator door.

The present invention relates to a method and a system of commissioning elevator, and an elevator system. The method includes obtaining at least one operation data of at least one elevator door, comparing the operation data with corresponding criterion operation data, and determining whether a deviation between the operation data and the criterion operation data exceeds a pre-set range, and if so, triggering a control over at least one control end relevant to the operation of the elevator door to make a deviation between the operation data re-obtained and the criterion operation data fall within the pre-set range. The invention will increase the efficiency in elevator commissioning and remove the adverse effects on elevator operation caused by factors such as Stack Effect, and thereby ensure good working condition and high security of elevators.

Disclosed is an elevator system having an elevator entryway, the elevator entryway including: a first door, which is an elevator door, a first controller operationally connected to the first door for opening and closing the first door to provide access to an elevator, wherein when the first door is closing: the first controller monitors for first instructions over a frequency applicable to light detection and ranging (LIDAR) and/or a radio detection and ranging (RADAR), and upon receiving the first instructions, the first controller executes the first instructions.

A method and system for controlling a movable door associated with a passenger compartment, the door moveable between an opened position and a closed position configured to provide access to, or egress from, the passenger compartment. The method includes monitoring a landing area of the elevator door with at least one sensor, and determining a level of urgency of an approaching passenger based on the information from the at least one sensor. If the level of urgency exceeds a predetermined threshold, modifying a closing of the elevator door based on the level of urgency. The method may also include modifying a closing speed of the elevator door if the level of urgency exceeds a predetermined threshold.

Embodiments include a system and method for controlling doors in a multi-door system. Embodiments a controller configured to control the multi-door system, wherein the multi-door system includes a first door and a second door, wherein the first door is on a different side than the second door, and one or more sensors operably coupled to the multi-door system and the controller, wherein the one or more sensors are configured to detect one or more conditions. The controller includes a processor, wherein the processor is configured to receive an input from the one or more sensors, wherein the input comprises at least one of call information and crowd sensing information, responsive to the input, prioritize an operation of the first door and the second door based at least in part on the input, and operate the first door and second door based on the prioritization.

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 a reflected 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.
