The present invention relates to a method and a system of commissioning elevator, and an elevator system. The method includes obtaining at least one operation data of at least one elevator door, comparing the operation data with corresponding criterion operation data, and determining whether a deviation between the operation data and the criterion operation data exceeds a pre-set range, and if so, triggering a control over at least one control end relevant to the operation of the elevator door to make a deviation between the operation data re-obtained and the criterion operation data fall within the pre-set range. The invention will increase the efficiency in elevator commissioning and remove the adverse effects on elevator operation caused by factors such as “Stack Effect”, and thereby ensure good working condition and high security of elevators.

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.

According to an aspect, there is provided an elevator communication system. The system comprises an elevator communication network configured to carry elevator system associated data; a plurality of elevator system nodes communicatively connected to the elevator communication network, wherein at least some of the plurality of elevator system nodes each comprises a camera associated with different landing floors, respectively, configured to provide image data about a respective landing floor area; and a controller communicatively connected to the elevator communication network and being configured to obtain image data from at least one camera during an evacuation situation; and provide, during the evacuation situation, to a node communicatively connected to the elevator communication network information for a graphical user interface comprising image data from a selected set of the cameras.

According to an aspect, there is provided an elevator communication system. The system comprises an elevator communication network configured to carry elevator system associated data and a plurality of elevator system nodes communicatively connected to the elevator communication network, wherein at least some of the plurality of elevator system nodes each comprises a camera associated with different landing floors, respectively, configured to provide image data about a respective landing floor area and wherein at least one of the plurality of elevator system nodes comprises a display arranged in an elevator car; and an apparatus communicatively connected to the elevator communication network, the apparatus being configured to receive an elevator call to a landing floor, and cause the display to display data provided by a camera associated with the landing floor in response to the elevator call to the landing floor.

An elevator system includes at least one autonomous unit for controlling an elevator and a multichannel-edge-gateway that builds communication between the autonomous unit and data resources on an IoT network. The multichannel-edge-gateway has more than one communication channel), wherein these communication channels provide data communicating using the same protocol or different protocols either synchronously or asynchronously. The multichannel-edge-gateway includes a channel assignment that automatically matches one of the communication channels to one of the protocols according to data to be sent from the multichannel-edge-gateway.

A calibration method and system for virtual buttons, an elevator, and a storage medium. The method includes: receiving a first designation regarding a layout of the virtual buttons in a virtual keypad zone; receiving a second designation regarding a number of the virtual buttons; and determining a position of each of the virtual buttons in the virtual keypad zone according to the first designation and the second designation.

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.

To have an integrated device management for a hybrid elevator environment, at least one converter for converting device management messages according to a second protocol used by one or more peripheral devices to be according to a first protocol, which is used by the device management of the elevator environment, is added to the elevator environment. Further, the device management is configured to update, in response to receiving a device management message containing, as device information, at least an identifier of a peripheral device, network information to contain the device information in the device management message.

The arrangement comprises a drive driving an electric motor, a contactor and a control circuit connecting a control coil of the contactor to a power supply. The control circuit comprises a manual control part provided with a manually operated first switch, and an electronical control part provided with an electronically operated second switch and a processor controlling the second switch. The first switch and the second switch are connected in series in the control circuit with the power supply and the control coil of the contactor so that de-energization of the control coil of the contactor may be done either by the first switch or by the second switch.
