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.

An elevator door control system, an elevator system, and an elevator door control method based on to-be-carried object grouping identification. The elevator door control system includes one or more three-dimensional sensors, arranged to capture three-dimensional data of to-be-carried objects in an elevator waiting region, wherein the three-dimensional data includes depth data; a data processing device, communicating with the three-dimensional sensor, and configured to receive and process the three-dimensional data, to provide grouping data of one or more groups obtained according to correlations between the to-be-carried objects and position data of each to-be-carried object in the elevator waiting region; and a control device, connected to an elevator door, communicating with the data processing device, and configured to control operation of the elevator door according to the grouping data and the position data.

A system and a method for operating one or more dynamic stoppers in an elevator car. A method includes receiving a command at one or more control panels to switch one or more dynamic stoppers from a first position to a second position. The one or more dynamic stoppers are installed on a platform of an elevator car. The elevator car includes one or more doors and the one or more control panels is installed in the elevator car. The method includes switching the one or more dynamic stoppers from the first position to the second position using one or more actuators coupled to the one or more dynamic stoppers, respectively.

An automatically controlled door arrangement, such as a floor door of an elevator installation, includes: at least one door leaf actively moveable between an open position and a closed position; a drive moving the door leaf between the open and closed positions; a controller controlling the drive; a sensor system detecting people or objects in front of the door leaf; and a data connection for data exchange with an external computer. The door arrangement receives and processes signals from the sensor system in the controller, sends query data to the external computer via the data connection based on the processed signals, receives instruction data from the external computer, and controls the door leaf drive taking into account the instruction data. The door arrangement provides monitorable, automated and, if possible, stepless access to buildings, for example, for robots, or receiving and storing delivered goods through the door arrangement.

A door operating arrangement in an elevator, including a door operating unit located in the elevator car including a door controller and a door drive as well as a door motor configured to open and close elevator car doors, optionally together with elevator landing doors, a DC bus connecting the door operating unit via a travelling cable of the elevator car with a DC power source of the elevator. The voltage level of the DC bus is between 40 V and 120 V, the DC bus is connected to a capacitor bank located in the elevator car having a parallel connection of at least two capacitors and a total capacity value of at least 75.000 μF, preferably at least 100.000 μF.

A door operation controller for an elevator includes at least one sensor arranged in a doorway at a landing for detecting moving direction and/or moving speed of a person or an object in or near the doorway during a time period from when the elevator door is opened until when the elevator door is closed at the landing. The controller is configured to control door operation in response to the detection of a person's or object's movement in or near the doorway at the landing.

A monitoring system for a conveyance system includes a pressure sensor mounted on a conveyance apparatus; an accelerometer mounted on the conveyance apparatus; and a controller arranged to: acquire accelerometer data by sampling the accelerometer; store the accelerometer data in a buffer; acquire pressure sensor data by sampling the pressure sensor; determine from the pressure sensor data that a start or stop of the conveyance apparatus has occurred; and upon said determination, analyse the accelerometer data to determine a first position within the accelerometer data, wherein the first position is a position at which the start or stop of the conveyance apparatus occurred. Both pressure and acceleration readings are combined to determine a point in time at which motion started or stopped. The pressure sensor is used first to determine a robust indication that the motion state has changed (started or stopped).

An illustrative example embodiment of an elevator door lock includes a latch that is moveable between a locking position and a released position. The latch includes a locking surface configured to engage a stop when the latch is in the locking position. A magnet is situated to magnetically attract a portion of the latch to selectively move the latch from the locking position into the released position.
