A smooth braking control method for an elevator, a smooth braking control device for an elevator, and an elevator brake. The elevator is provided with an elevator brake including a fixed part and a moving part, and in a first state, by driving the moving part to move toward an elevator power device so that a friction member in the moving part contacts the elevator power device, the elevator brake provides a braking force to stop an elevator car, and in a second state, by outputting an electromagnetic force from an electromagnetic member in the fixed part, the friction member is disengaged from the contact with the elevator power device.

A system includes an elevator system including an elevator car. The system also includes a control system configured to receive a crowd reduction indicator, determine an elevator car load reduction for the elevator car based on the crowd reduction indicator, adjust an elevator car load limit based on the elevator car load reduction, and trigger a mitigation action in the elevator system based on detecting a condition that exceeds the elevator car load limit.

An illustrative example method of controlling an elevator situated in a hoistway of a building includes detecting sway of the building, determining characteristics of the detected sway including a plurality of frequencies and associated periods of the sway, determining an expected sway of an elongated member of the elevator system based on the determined characteristics, and controlling at least one of position and movement of an elevator car in the hoistway based on the expected sway.

A lift system comprises a call input device and at least one touchscreen for inputting a call for a lift. The touchscreen has at least one functional identifier. When a functional identifier is touched, at least one input signal is generated. The call input device converts into a special input mode for a time-specific or location-specific generation of several input signals.

An elevator system includes a control unit, a bus, a plurality of bus-nodes connected via the bus with the control unit, and a plurality of safety-state detection devices connected with the control unit via the bus-nodes. A method of commissioning the elevator system includes the steps: A) verification by the control unit of the safety-state detection means that are connected to the bus; B) checking of the functional capability of the safety-state detection means that are connected; C) checking by the control unit of the safety functions of the elevator system based on a change in state of a safety-state detection means; and D) release of the elevator system for a normal operation only after positive execution by the control unit of the steps A) to C), wherein the release is accompanied by a change in state of the control unit from an unsecured state into a secured state.

An elevator system includes: key switches, provided at a hall, used in an evacuation operation to select either a shuttle operation request mode requesting a car to shuttle between an evacuation floor and a rescue floor, or an evacuation completion mode indicating completion of evacuation; a first notification mechanism provided in the car; and an elevator controller switching between normal operation and the evacuation operation, determining, in a case at least one of the key switches is switched to the evacuation operation, that a floor at a hall whose key switch is in the shuttle operation mode is a rescue floor and a floor at a hall whose key switch is in the evacuation completion mode is an evacuation completion floor, and making, in a case a hall button provided at the hall of the evacuation completion floor is operated, the first notification mechanism notify of the evacuation completion floor.

An elevator system includes an elevator car; a machine to impart motion to the elevator car; a brake to stop rotation of the machine, the brake comprising a first coil and a second coil, wherein removing power from the first coil and the second coil applies the brake to the machine; and a controller in communication with the brake, the controller configured to connect the first coil and the second coil in one of a first electrical configuration and a second electrical configuration.

A device and a method for controlling an apparatus being an elevator, an escalator or automatic doors are provided, by which it is detected whether a fault is present in the apparatus, it is determined, when the fault is present, whether an automatic fault clearing may be carried out, and if it is determined that the automatic fault clearing may be carried out, the automatic fault clearing is performed by automatically clearing one or more faults.

Embodiments herein are directed to an elevator system having at least one movable component and at least one component generating a reference signal. The elevator system includes a controller, an output signal, and a controller tuner. The controller generates a control signal. The output signal is indicative of a movement of the at least one movable component of the elevator system based on the control signal. The controller tuner is communicatively coupled to the controller. The controller tuner receives the output signal and the reference signal to calculate an error signal. The controller tuner uses the error signal to calculate a corrected control signal and transmits the corrected control signal to the controller. The corrected control signal manipulates the control signal generated by the controller to change the movement of the at least one movable component.

A method for deploying a controller to an elevator system includes generating a request to at least one other controller for obtaining at least one parameter relating to a deployment of the controller to the elevator system, receiving a response, and in response to detection that the at least one parameter in the response comprises a set of operational parameters, initiating a configuration procedure, and in response to detection that the at least one parameter in the response does not comprise the set of operational parameters, deriving an identifier of the elevator system included as the at least one parameter in the response and generating a request including the identifier of the elevator system for obtaining the set of operational parameters. An elevator system is configured to perform the method.
