According to an aspect, there is provided a method for determining a sequence of bus nodes in a multi-drop communication bus. The method includes for each bus node: sending a request to the bus node using an bus node physical identifier to set the bus node to a loopback mode; transmitting at least one signal to the bus node via the multi-drop communication bus; receiving from the bus node a loopback signal caused by the at least one signal; and measuring a roundtrip delay between the at least one signal and the loopback response signal. The method further includes solving the physical order of the bus nodes in the multi-drop communication bus based on the roundtrip delays.

An exercise necessity degree determination unit (13) determines an exercise necessity degree being a degree to which an elevator user needs to exercise, who uses an elevator (50) provided in a building provided with an inter-floor travel means other than the elevator. A floor decision unit (14) changes based on the exercise necessity degree of the elevator user determined by the exercise necessity degree determination unit (13), at least one of a boarding floor and an alighting floor of the elevator (50) from a floor that the elevator user prefers to another floor so as to let the elevator user use the inter-floor travel means before the elevator user reaches a destination floor to which the elevator user intends to go.

An elevator system has a rail system and a shaft door assembly on each of a plurality of floors of a building. The rail system has an electrically conductive guide rail that extends along the plurality of floors and guides a vertically movable component of the elevator system, and an electrically conductive bracket on each of the floors anchoring the guide rail to a wall of the building. The guide rail is electrically conductively connected to each of the brackets. Each shaft door assembly has a movable shaft door for openable closing of a shaft opening of the floor and an associated control device and/or drive device for moving the shaft door; wherein the control device and/or drive device is supplied with electrical energy via two electrically conductive paths with a first of the electrically conductive paths being formed over at least parts of the rail system.

A system for providing an automatic software upgrade assistant for remote elevator monitoring experts using machine learning. The system performs operations that include receiving a request from a requestor to install a software upgrade on a controller of an elevator component, the software upgrade dependent on at least one software program being installed on the controller. It is determined whether the at least one software program is installed on the controller. Based at least in part on determining that the at least one software program is installed on the controller: an elapsed time to complete the installation of the software upgrade on the controller is predicted; and an indication is output to the requestor that the software upgrade is permitted to be installed on the controller and the predicted elapsed time to complete the installation.

Various example embodiments relate to control of passenger traffic group systems. In particular, some example embodiments relate to eliciting user preferences for call allocations for the passenger traffic group system. At least one user preference may be considered when determining a set of candidate control parameters for the passenger traffic group system. At least one representative of the operation of the passenger traffic group system may be displayed to the user based on a simulation of the passenger traffic group system. The user may be enabled to accept the candidate control parameters or modify the user preferences to generate a further set of candidate control parameters. Apparatuses, methods, and computer programs are disclosed.

A method includes recording a primary destination dispatch request from a primary passenger at a first floor position via a destination dispatch controller 115, identifying a terminal floor, providing a terminal floor call signal to the elevator control system via an overlay controller 110, moving an assigned elevator car in a travel direction of the terminal floor, recording at least one secondary destination dispatch request from a secondary passenger at a respective at least one secondary floor position via the destination dispatch controller, approximating a position of the assigned elevator car, determining a target floor position via the destination dispatch controller, entering a target floor call corresponding to the target floor position at a calculated time to stop the assigned elevator car at the target floor position, cancelling all pending calls via the elevator control system 102, and entering at least one recorded destination dispatch request to the elevator control system.

In an elevator controlling panel, an opening portion of a front surface of a case is opened and closed by a front cover. A bent portion is disposed on a first end portion in a width direction of the front cover. A slit is disposed on the bent portion. A shaft member that guides opening and closing operations of the front cover by being moved relatively along the slit, and that also stops the front cover from dislodging from the case, is disposed on a side surface of the case. The slit has a shape such that the opening portion is opened by sliding the front cover forward relative to the controlling panel main body and then upward.

A method of operating an elevator system is presented. The method comprises controlling, using a controller, a plurality of components of the elevator system. The controlling comprises operating at least one of an internal power source, an elevator car, a drive unit, a power conversion device, and a brake. The method also comprises detecting, using the controller, when an external power source is unavailable; deactivating, using the controller, the power conversion device when an external power source is unavailable; and determining, using the controller, a mode of the elevator car. The mode includes at least one of a motoring mode and a near balance mode. The method further comprises connecting, using the controller, to an internal power source, when at least one of the motoring mode and the near balance mode is determined; and increasing, using the internal power source, voltage of the drive unit.

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.
