An elevator device includes an operation control unit (18), a storage unit (22), a transmission unit (23), a determination unit (25), and a recovery unit (26). When an inspection operation is interrupted by the operation control unit (18), the transmission unit (23) transmits inspection data stored in the storage unit (22) to a plurality of specific devices (20). The determination unit (25) determines whether or not recovery conditions are satisfied on the basis of a plurality of responses from the devices (20) to which the transmission unit (23) transmits the inspection data. For example, the recovery unit (26) restores a normal operation when the determination unit (25) determines that the recovery conditions are satisfied.

A method of operating an elevator system including: controlling, using a controller, a plurality of components of the elevator system, controlling includes operating at least one of an internal power source, an elevator car, a drive unit, a power conversion device, and a brake; detecting when an external power source is unavailable; deactivating the power conversion device when external power source is unavailable; determining at least one of a motoring mode and a near balance mode; connecting to an internal power source when at least one of the motoring mode and the near balance mode is determined; activating the power conversion device 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, the internal power source is configured to provide an uninterrupted power to drive unit when the external power source is unavailable.

Provided is an elevator safety system including: a plurality of communication controllers configured to communicate, over a network, signals including a safety control signal; a control device connected to a first communication controller, which is one of the plurality of communication controllers, and configured to execute operation control of the elevator, in which each of the plurality of communication controllers includes an error ratio measurement instrument configured to measure an error ratio of the network, based on a bit error of data that is received over the network, and in which the control device is configured to execute the operation control by switching the operation state of the elevator in accordance with the error ratio measured by the error ratio measurement instrument that is included in the first communication controller.

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.

A method and a device configures a floor allocation of at least two operating panels of an elevator system having an elevator car and an elevator control unit in a building having at least two floors, wherein a respective one of the operating panels and an elevator door are located on each floor of the building, wherein a door contact unit is arranged on the elevator door, wherein the door contact unit is opened with the elevator door open, and wherein the elevator car moves vertically between the at least two floors. According to the method and device, the door contact unit is connected with the operating panel on each floor. The elevator car is moved to each floor and the elevator door is opened. The operating panel detects the open door contact unit and allocates the approached floor to the operating panel depending on the position of the elevator car.

A method and system for generating automatic destination calls for an elevator system, in which system is a revolving door. A passenger approaching the revolving door or in a door sector of the revolving door is identified, a destination call to the home floor of the passenger is generated and the elevator serving the passenger is announced at the revolving door.

A method and a device configures a floor allocation of at least two operating panels of an elevator system having an elevator car and an elevator control unit in a building having at least two floors, wherein a respective one of the operating panels and an elevator door are located on each floor of the building, wherein a door contact unit is arranged on the elevator door, wherein the door contact unit is opened with the elevator door open, and wherein the elevator car moves vertically between the at least two floors. According to the method and device, the door contact unit is connected with the operating panel on each floor. The elevator car is moved to each floor and the elevator door is opened. The operating panel detects the open door contact unit and allocates the approached floor to the operating panel depending on the position of the elevator car.

An operational entity for controlling movement of a plurality of elevator cars of a multicar elevator system includes a user interface having a first input element and a second input element. The user interface generates, on the basis of the first input element, an indication of selection of at least one elevator car from among the plurality of elevator cars to be moved; and generates, on the basis of the second input element, one or more control signals indicative of a request to control the movement of the selected at least one elevator car in a predefined direction. A multicar elevator system including the operational entity is provided.

According to an aspect, there is provided a solution for evaluating a configuration associated with an elevator. An update request may be received for a new configuration to be deployed with the elevator. It may be checked, from a memory, whether the new configuration exists in the memory. When the new configuration does not exist in the memory, a request for performing configuration upgrade tests associated with the elevator may be issued. The request causes a testing environment to obtain information associated with a first testing procedure using a software package associated with an existing configuration used in the elevator and to obtain information associated with a second testing procedure using a software package associated with the new configuration to be deployed with the elevator. A diagnostic report associated with the first and second testing procedures may be received and stored in the memory. The data stored in the memory may be evaluated to generate at least one prediction associated with the new configuration, and the at least one prediction may be sent in response to the update request.

In a system with an elevator system, a host can grant a visitor access to a building and switch the elevator system into a visitor operating mode in order to transport the visitor to a destination floor. The host can initiate a movement of the elevator car to a first defined floor, on which a visitor would like to enter an elevator car, by means of an input on a mobile device. A camera arranged in the elevator car and a camera recording, which is produced by means of said camera and displayed on the mobile device, enable the host to check if only the user is located in the elevator car. If this is the case, the host can initiate the movement of the elevator car to the destination floor by means of an additional input on the mobile device.
