The invention relates to a method for resetting a shaft access monitoring system of an elevator system. The method comprises: receiving an input from a user interface arranged in the elevator system, the input is provided with at least one input device of the user interface arranged to control an operation of the elevator system; comparing the received input to a reference value; and setting, in accordance with a comparison between the received input and the reference value, a detection result to express one of the following: (i) the shaft access monitoring system shall be reset, (ii) the shaft access monitoring system shall not be reset. The invention also relates to a control unit, to an elevator system and a computer program product.

An elevator arrangement includes an elevator group. A connection to a remote elevator system group controller is monitored. Traffic is served by the elevator group as controlled by a local elevator system group controller, when the connection is down. Traffic is served by the elevator group as controlled by the remote elevator system group controller, when the connection is up.

A method and a system for determining the position of an elevator car of an elevator system, which car is arranged for travel in an elevator hoistway, includes equipping the elevator car with an acceleration sensor that registers acceleration data in a computing unit, calculation by the computing unit of the current position and/or of the velocity of the elevator car, and equipping the elevator system with an image-recording unit, which unit records recorded images of the elevator hoistway. The computing unit compares the recorded images with current mapping images of the elevator hoistway to determine an image-based current position of the elevator car. Finally, the computing unit undertakes a recalibration of the current position using the image-based current position.

A conveyor system includes a conveyor control unit, one or more conveyor components, and a communication system for providing data frame-based communication between the conveyor control unit, the one or more conveyor components, and/or one or more external or remote systems. The communication system includes: at least two virtual local area networks (VLANs) separated by respective tags, a first switch device configured to connect the one or more conveyor components to at least one of the at least two VLANs, a second switch device configured to connect the conveyor control unit and the one or more external or remote systems to at least one of the at least two VLANs, and a trunk link configured to carry the data frames belonging to the at least two VLANs between the first switch device and the second switch device. An elevator system and a conveyor device are also discloses.

An elevator system includes a data network and is operated according to a method for identifying a component of the elevator system. The data network has at least one network node including a component of the elevator system. The component of the network node can be identified such that a control unit of the elevator system controls a light source in order to generate a light signal to indicate the network node. The component can be assigned to a light sensor when the light sensor detects the light signal, and the control unit is notified of the assignment of the component.

A passenger conveyor performance rating system includes a user device and a computing server. The user device obtains geographical information of the passenger conveyor system and displays a graphical user interface. The graphical user interface receives a first input indicating an operating performance of an individual passenger conveyor and a second input indicating at least one operation fault of the individual passenger conveyor. The computing server receives first data indicating the operating performance, second data indicating the at least one operation fault, and third data indicating the geographical information. The computing server further determines a faulty passenger conveyor system based on the first data and the second data and determines the geographical location of the faulty passenger conveyor system based on the geographical information received from the user device.

The disclosure relates to an elevator system consisting of a plurality of elevator carriages, a shaft system, a drive system for separately moving the elevator carriages within the shaft system, as well as a safety system having a plurality of safety nodes designed to bring the elevator system into a safe operating mode if an operating mode of the elevator system, which deviates from the normal operation mode, is detected. The elevator carriages, the shaft system and the drive system form a functional unit. One of the safety nodes is always assigned to one of the functional units, wherein the safety nodes are each connected to at least another safety node through an interface for transmitting data. Each safety node includes at least one sensor, which detects an operating parameter of the corresponding assigned functional unit. A control unit evaluates the operating parameter detected by one of the sensors of the respective safety node and, taking into account the data transmitted by at least another safety node.

The monitoring system (1) includes an elevator control panel (2), a monitoring device (5), an elevator control panel (3), and a monitoring device (6). The monitoring device (5) includes a communication circuit (14), a control circuit (13), and a power supply circuit (12). The monitoring device (6) includes a control circuit (26) and a power supply circuit (25). The power supply circuit (12) supplies power from the elevator control panel (2) to the control circuit (13). The control circuit (13) supplies power to the communication circuit (14). The control circuit (13) and the control circuit (26) are connected via a communication wire (32) so that information can be transmitted to the control circuit (13).

A method of passenger conveyance control includes receiving a destination request; tracking a passenger who entered the destination request while in a waiting area; and canceling the destination request in response to the passenger leaving the waiting area.

An elevator operation managing device capable of reducing a switching of passengers at a time of getting on and getting out of a car. The elevator operation managing device includes an in-car position acquisition unit and a car allocation acquisition unit. The in-car position acquisition unit obtains an in-car position of a user based on layout information and a congestion degree obtained in a congestion degree acquisition unit. The car allocation acquisition unit performs a car allocation to allocate the user to the car based on a received boarding floor and destination floor and the in-car position obtained in the in-car position acquisition unit.
