摘要:
A vibration reduction apparatus for an elevator includes acceleration sensors for detecting vibrations of a elevator car, controllers for calculating forces to be applied to the elevator car, based an signals output by the acceleration sensors, and actuators for applying forces to the elevator car in accordance with the forces calculated by the controller. A dead band filter, which has a dead band region corresponding to noise level of the acceleration sensors, and an integrator, which integrates the signals output by the acceleration sensors after filtering by the dead band filter, are located in the acceleration sensors, or in the controllers, or between them.

Elevator system hall fixtures such as lanterns, hall call button switches and lights, gongs, and floor position indicators are connected to a controller via wireless transceivers. The controller can be a system, group, and/or car controller. A low power wireless system connects all fixtures on one hallway, with a higher power wireless system connecting each hallway with the appropriate controller.

In an operating panel for an elevator, a button is located at a touch panel. A button frame is disposed over a display surface member of the button, a button cap is embedded within a button accommodating portion of the button frame. The button portion is operated by pushing the button cap. A metal dome member generated a click feeling at the time of operation is located between accommodating portion and the button cap.
摘要:
A definite switching-off of drive equipment for elevators is accomplished with a control at an input side external of a frequency changer power unit that ascertains the presence or the absence of monitoring signals which are derived from the mains voltage at the input of the frequency changer power unit. Upon ascertaining the presence of one or more such signals when the drive is at standstill, the input side control interrupts the energy flow to the frequency changer power unit by generating a switching-off signal to a switching device to disconnect the mains voltage.

A braking device for load carrying cars in vertical conveyor installations with elastic suspension apparatus holds fast to guiderails to prevent vertical displacements and vertical vibrations while stopped at landings. The braking device contains integrated sensors for registering the holding forces occurring between the load carrying car and the guiderails. Before travel of the car continues, the signals from these sensors enable a drive regulator to adjust via a drive unit the tensile force in the suspension apparatus carrying the car in such a manner that the braking device is relieved and can be opened without generating a jerk on the load carrying car.

A load detector for an elevator having a cage moving up and down in a shaft for transporting passengers and a cable hanging the cage, including a relative position detector configured to detect a relative position of the cage against the shaft; and a calculator configured to calculate a change of the relative position between the position of the cage just after landing at a floor and the position of the cage just before leaving the floor, and a load of the cage on the basis of the change of the relative position caused by an expansion and contraction of the cable.

In order to make it possible to transmit and receive information between terminals and to reduce the number of wires used for an elevator in a building in an elevator system by transmitting and receiving information through wireless transmission even if a very weak radio wave having a narrow communicable range is used, an elevator control unit, a car terminal and floor terminals are individually provided with short distance wireless transmitting/receiving units having a communicable range of nearly a 2-floor distance (5 to 6 m) using very weak radio waves. The radio waves are received and transmitted between the wireless transmitting/receiving units located within the communicable range to transmit information by a relaying method of sequentially transferring information from terminal to terminal until it reaches a final destination.

A drive machine for elevators includes a rotatable drive sheave over which a main cable for hanging an elevator cage is wound, a stationary shaft for supporting rotation of the drive sheave and bearing a load applied to the drive sheave by the main cable, a field magnet attached to the drive sheave, constituting a part of an electric motor, and including at least one pair of magnetic poles, an armature attached to the stationary shaft facing the field magnet and constituting another part of the motor, and a field magnetic pole detector for detecting a magnetic pole of the field magnet rotating together with the drive sheave.
摘要:
The elevator communication system generally provides a computer device installed in an elevator cab. The computer device is configured with peripheral devices to display visual and audio information to cab riders. The computer device receives information content from several sources, including a networked server system. The server system communicates information to the computer device for presentation to passengers in the elevator. The computer device may also be connected to an elevator controller so that the computer device can present information based on current and future destination floors of the elevator cab. The elevator communication system queues and orders the received informational content based on received selection data, thereby selecting which information is presented to elevator riders.
摘要:
A magnetic guide system for an elevator, including a movable unit configured to move along a guide rail, a magnet unit attached to the movable unit, having a plurality of electromagnets having magnetic poles facing the guide rail with a gap, at least two of the magnetic poles are disposed to operate attractive forces in opposite directions to each other on the guide rail, and a permanent magnet providing a magnetomotive force for guiding the movable unit, and forming a common magnetic circuit with one of the electromagnets at the gap, a sensor configured to detect a condition of the common magnetic circuit formed with the magnet unit and the guide rail, and a guide controller configured to control excitation currents to the electromagnets in response to an output of the sensor so as to stabilize the magnetic circuit.
