The present invention provides an elevator system which prevents interruption of communication with a wireless communication device installed in a car, while suppressing the cost. The elevator system includes the car ascending/descending in a hoistway, multiple hoistway wireless communication devices installed in the hoistway, and a car wireless communication device installed in the car. The elevator system is configured to allow communication between the hoistway wireless communication device and the car wireless communication device. A spacing between the hoistway wireless communication devices which are installed at positions near a vertical center of the hoistway is smaller than a spacing between the hoistway wireless communication devices which are installed at positions farther from the vertical center.

An elevator system has a drive, a car, a plurality of safety function components for providing safety functions at various positions, and a safety monitoring system with a plurality of safety monitoring units for monitoring all of the safety function components. The monitoring units have an input interface for reading in data or signals and an output interface for outputting control signals to an assigned member of the safety function components, at least some of the monitoring units being connected via data exchange channels. The monitoring units are organized in a master-slave hierarchy, with one unit designed as a master unit, and at least one other unit designed as a slave unit. The decentralized and distributed monitoring units, each having data processing capability, and the master-slave organization result in the elevator system exhibiting a high security level with low cabling complexity and cost expenditure, in particular for high rise elevators.

A method and a corresponding device for exchanging a component in a passenger transport system are proposed. In this case, a digital double dataset, which is digitally stored in a computer and can also be processed, exists parallel to the passenger transport system, wherein said digital double dataset comprises data concerning physical properties of the passenger transport system. The method comprises the steps of physically exchanging the component by removing an existing component from the passenger transport system and replacing the existing component with a replacement component; and exchanging component data concerning physical properties of the component in an at least partially automated manner by replacing component data concerning physical properties of the existing component with component data concerning physical properties of the replacement component in the digital double dataset.

A building settling detection system having at least one sensor configured between a guide rail track of an elevator system and a pit of the elevator system and a controller in communication with the at least one sensor, the controller configured to monitor an output of the at least one sensor and transmit a notification to a remote location when the output of the at least one sensor meets or exceeds a predetermined threshold indicating that the predetermined threshold is met or exceeded.

A storage locker for drone delivery provides for weathertight doors that open automatically on sensing the approach of a drone and close to cover the package once deposited by the drone. The storage locker may be operated in conjunction with an elevator to allow elevated placement, removing drones from the vicinity of interfering structures, people, and pets.

A system includes a centralized controller configured to coordinate movement of a plurality of elevator cars in a multicar hoistway. The system also includes a plurality of car controllers configured to communicate with the centralized controller through a plurality of centralized control flows, establish two or more car-to-car control flows between at least two of the car controllers, and exchange an elevator car status between at least two of the car controllers. Movement of at least two of the elevator cars in the multicar hoistway is controlled based on the elevator car status and one or more commands received through at least one of the centralized control flows.

A car mover for autonomously moving an elevator car along a lane in a hoistway, including: first and second wheels of the car mover, configured to apply a pinch force against a track therebetween and to rotationally drive along the track, by respective first and second wheel motors of the car mover; and a controller configured to execute: a gap control self-learning module, wherein based on adjustment data, one or more operational parameters applied by one or more of the first and second wheel motors are adjusted; and a gap feedback control module, wherein based on one or more of a first lateral clearance adjacent the first wheel on the track and a second lateral clearance adjacent the second wheel on the track, torque applied by one or more of the first and second wheel motors is increased or decreased.

A safety device for a path that is traversed to enter a region in which danger to an individual is heightened due to operation of a machine includes at least one sensor installed along the path so as to detect the individual thereat, which compels the sensor to generate a signal. A lockout mechanism is deployed that compels the machine into a non-operational state in response to receiving the signal from the sensor. The lockout mechanism ensures the machine remains in the non-operational state when the signal from the sensor is removed therefrom. A reset circuit is deployed that, in response to activation thereof, compels the lockout mechanism to allow the machine into the operational state from the non-operational state.

A target floor registration unit for use in an elevator system including a unit controller configured to receive assignment information, a user detection device operably coupled to the controller; wherein the user detection device is configured to determine whether a user is present at the target floor registration unit, and a display part; the display part configured to dynamically display the assignment information based in part on whether the user is present at the target floor registration unit.

The invention allows enhancing radio signal coverage in an elevator environment. An elevator antenna pair comprises a primary antenna that is configured to transmit and receive radio frequency signals with an external wireless communication network. The elevator antenna pair further comprises a secondary antenna that is communicatively connected to the primary antenna and configured to transmit and receive radio frequency signals with at least one radio frequency transceiver in an elevator car. The primary antenna is arranged within an elevator landing signalization unit, and the secondary antenna is arranged inside an elevator hoistway.
