An elevator system includes: a destination call registration device which accepts an operation of registering a destination call by specifying a destination floor; an exit floor selection part provided in the destination call registration device and by use of which a user selects an exit floor provided with an exit of a building as a destination floor of the destination call; an exit floor determination part which determines, on the basis of predetermined conditions, which floor is the exit floor from candidates for an exit floor which are set beforehand as floors capable of being selected as the exit floor among plural floors of the building; and a destination call registration part which registers the destination call in which the specific floor determined as the exit floor by the exit floor determination part is a destination floor in the case the exit floor selection part is operated by a user.

A context-aware system for elevator operation includes an elevator operable to move up and down, and having an internal operating panel allowing selection of a floor to cause the elevator to stop, floor operating panels to call the elevator, and to indicate both a floor selected from the internal operating panel and a floor where the elevator has been called among other floors, a system control unit to adjust a movement direction and a movement speed of the elevator by detecting the floor selected from the internal operating panel and a floor operating panel from which the elevator has been called among the floor operating panels, and a driving unit to drive to move the elevator by control of the system control unit. Therefore, a user may predict a floor at which the elevator is scheduled to stop, and a movement speed may increase and power consumption may reduce.

An elevator system stopping control generates the difference between the actual speed value and a set point speed value on the transition from an unregulated travel phase to the regulated arrival or braking phase and prevents that difference from becoming effective so that the travel comfort is not impaired and the stopping accuracy remains assured. For this purpose, a multiplication factor is formed from the actual speed value and an associated nominal speed value by means of a divider during the travel phase before the onset point of braking and stored during the arrival phase in a memory. Stored in a travel curve memory are travel-dependent set point speed values, which values are multiplied by the factor by means of a multiplier and conducted as set point signals to a motor speed regulating circuit during the arrival phase.

A traction elevator system including an elevator car driven by a drive arrangement having electrically isolated high and low speed components. Fixed AC and controllable DC voltages are selectively applied to the high and low speed components, respectively, at predetermined portions of the run, to control the drive torque to provide smooth operation of the elevator car.

An apparatus for transmitting control signals to a transportation installation, such as typically an elevator wherein a respective diode matrix codes the cabin and floor calls, and the outputs of which are connected by common call lines with the inputs of a call memory system. A coding device is provided for coding the elevator cabin position and comprises switches attached to the elevator cabin and actuation elements arranged in the cabin chute. An actuation element is provided for each floor change and is associated with the changing binary place of the code word associated with the floor. The switches are connected by means of a respective series connected diode of a coupling system with the outputs of the cabin diode matrix and by means of the call lines with the input of a cabin position memory. A logic circuit serves to switch the diodes of the cabin and floor diode matrixes into their non-conductive or reverse state during travel of the cabin and for a given time span following standstill thereof and to switch the diodes of the coupling system into their forward or conductive state, and to disconnect the call lines from the call memories. This logic circuit, during the remaining time of standstill of the cabin, switches the diode matrixes into their conductive or forward direction and the coupling diodes into their blocking state or reverse direction as well as connecting the call lines with the call memories.

A storey selector device for elevators and the like has a number of destination selector switches for different stopping levels which connect different tappings of a fixed resistance to one end of a sensing diagonal of a Wheatstone bridge, the other end of the sensing diagonal being connected to the slider of a potentiometer controlled by movement of the elevator carriage. The sensing diagonal incorporates unidirectional conductive elements responsive to imbalance currents in opposite directions to control movement of the elevator motor in opposite respective directions to bring the elevator carriage to the selected destination level.
