The at least one elevator system component is configured to at least one of receive an ethernet frame from the control entity and to send an ethernet frame to the control entity.

There are provided measures for performing a configuration control in relation to an elevator, an escalator and automatic doors in a remote manner. Such measures exemplarily comprise determining a status of a component of said control apparatus, detecting whether a change with respect to said component has occurred based on said status, defining configuration parameters for said component, if it is detected that said change has occurred, and initiating transmission of said configuration parameters to said control apparatus.

A communication system for an elevator system, a communication method for an elevator calling system, and a computer-readable storage medium for implementing the method. A communication system includes at least two communication node groups, each of the communication node groups comprising wireless modules deployed at a plurality of locations of the elevator system, one of the wireless modules in each of the communication node groups is set as the first node and the other wireless modules are set as the second node; a master node, which can be configured to establish a communication connection with one of the first nodes as designed, the first node in each of the communication node groups can be configured to establish a wireless communication connection with the second node belonging to the same communication node group and establish a wireless communication connection with the first node in the adjacent communication node group.

An elevator safety supervising entity (SSE) includes a car safety supervising unit (SSU) controlling functions of car safety components and having at least one car sensor sensing car-related parameters, a head SSU controlling functions of shaft safety components and having at least one shaft sensor sensing shaft-related parameters, and a data linkage transmitting signal data between the SSUs. Both SSUs detect a failure in the other one of the SSUs and in the data linkage signal data transmission and in response switch from a normal operation mode to a failure operation mode. In the failure operation mode, the SSUs operate autonomously to keep the elevator operative at least temporarily with a sufficiently high safety even when functions of the elevator SSE are disturbed due to failures and e.g. passengers may be evacuated from the elevator car before completely stopping elevator operation.

An elevator brake performance detection method includes controlling an input voltage or current of the electromagnetic member so that the elevator brake enters the braking state, and recording a corresponding current data trajectory of the electromagnetic member based on time characteristic; determining a first target point and a second target point in the current data trajectory according to the current data trajectory, the first target point and the second target point being a first peak point in the current data trajectory, and a start point at which the current value changes from decreasing to increasing in the current data trajectory, respectively; and calculating a time difference between the first target point and the second target point as a braking time of the elevator brake.

A method and an apparatus for computing allocation decisions in an elevator system is provided. Historical passenger batch journey data relating to the elevator system is obtained, wherein each passenger batch journey includes an origin and a destination floor of the journey, the number of passengers of the journey and the time of the journey. Historical passenger traffic statistics are constructed based on the passenger batch journey data, and expected calls are modelled based on the passenger traffic statistics. The modelled expected call is taken into account in computing subsequent allocation decisions in the elevator system.

A method of operating a building elevator system having a plurality of elevator systems organized into multiple elevator groups including: receiving an elevator call from a destination entry device in communication with the building elevator system; obtaining a favorability score from each of the multiple elevator groups of the building elevator system; determining an elevator group of the multiple elevator groups with the highest favorability score; and routing the elevator call to the elevator group of the multiple elevator groups with the highest favorability score.

There is provided a smart access control device (SACD) for access control to an elevator system, the SACD comprising a receiver, a processing unit, and a communication unit for receiving by the receiver an identifier from a user device associated to a user and for automatically determining by the processing unit a destination floor associated to the user based on the identifier received and access control data stored in a storage unit accessible to the processing unit, and for generating and transmitting a signal to the elevator system for automatically initiating an elevator car trip for the user to the destination floor determined by the processing unit. There is also provided a user device configured to be in communication with a smart access control device (SACD) for access control to an elevator system.

In an elevator system, a measurement system is provided in addition to an elevator car, an elevator controller and a transferring device configured to transfer electrical energy and/or information between the elevator car and the elevator controller. The measurement system has a transmitting device and a detection device which can be positioned separate and remote from the transmitting device by an air path. The detection device receives a measurement signal emitted from the transmitting device as electromagnetic radiation via the air path and converts it into an electrical signal. The transmitting device receives the electrical signal via the transferring device, determines a propagation time of the measurement signal over the air path by means of the electrical signal, and determines a distance (d) between the transmitting device and the elevator car by means of the propagation time.

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.
