An elevator according to an aspect of the present invention includes a car speed detection device that measures car speed, an emergency braking device that comes into press contact with a guiderail and emergently stops a car when the car speed exceeds a threshold, an electric actuating unit that electrically actuates the emergency braking device, a battery that supplies electric power when commercial power supply is interrupted, and a safety control unit that monitors abnormality of the elevator and controls operation of the electric actuating unit. The safety control unit measures remaining power of the battery when the electric power is supplied from the battery, determines operation propriety of the emergency braking device at commercial power supply restoration time based on transition of battery remaining power, and controls operation of the electric actuating unit at the commercial power supply restoration time based on content of the determination.

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.

Disclosed is an elevator system including a system controller, wherein the system controller is configured to: render a plurality of determinations for effecting elevator service during a lockdown condition, including a first determination that an elevator car is transporting a first passenger to a first floor, a second determination that a lockdown event is occurring at a second floor, a third determination for the elevator car to transport the first passenger to a third floor to avoid travel proximate the second floor, and execute one or more communications including: a first communication to an elevator car controller for the elevator car to effect the third determination.

Provided is an elevator door control device capable of safely closing a door of an elevator when a power failure occurs and preventing an extra burden from being placed on a rescue worker. The elevator door control device according to the present invention includes a door dynamic braking control circuit (15) that performs, when a power failure occurs in a condition in which the door of the elevator is in an intermediate position, dynamic braking control of a door motor (2) until full close of the door is detected and deactivates the dynamic braking control when the full close of the door is detected.

A method of monitoring a running state of a machine passenger capable of wirelessly interacting with an elevator system, which includes a judgement step and a first state determination step; in the judgement step, judging whether a response command for state polling information fed back from the machine passenger is received, and judging whether first state representation information actively sent from the machine passenger for representing that its running state is abnormal is received; and in the first state determination step, determining that a respective machine passenger is in an abnormal running state based on a first judgement result of not receiving the response command and a second judgement result of receiving the first state representation information.

According to an embodiment, a method of operating an elevator system during a fire evacuation including: receiving a fire detection from a fire alarm system indicating a fire; detecting a fire intensity using a fire quantity measurement system; and determining a discharge landing for the elevator system in response to at least the fire intensity.

Embodiments are directed to an intelligent elevator control system utilizing wireless user location awareness. An embodiment of non-transitory computer-readable storage mediums includes instructions for detecting a mobile device of a user at a first wireless access point for an elevator system; requesting authentication of the user for use of the elevator system from an authentication server; upon receiving authentication for the user from the authentication server, the authentication identification of a first authorized destinations for the user, calling, by an elevator control, a first elevator for the user; and directing the first elevator to the first authorized destination.

An elevator control cabinet used in an elevator system includes a voice communication apparatus having a microphone, an electronic control arrangement, an evaluation unit, and a cabinet housing having at least one cabinet door. The voice communication apparatus is used to execute a service or emergency call or establish a communication between the elevator and a public communication network. The microphone detects a surrounding noise in the control cabinet. The evaluation unit converts the detected noise into a noise pattern and then compares this noise pattern with a reference sound pattern that is predetermined for a surrounding noise in the cabinet housing with the open or closed cabinet door. This reference sound pattern is saved in a storage unit of the control arrangement. In dependence on a result of the comparison, the evaluation unit will recognize whether the cabinet door is open or closed.

Modern large buildings and public places are equipped with a plurality of elevators, exits and points of interest for fluent movement. The passenger flows in a building or public place can be traced and modelled by using statistics and information regarding current state of the modelled building or public place. The information derived from this model can be used for controlling elevators, escalators and similar in the building more efficiently. The same information may be used also for guiding passengers in the building or public place to use other transportation means so that the duration high traffic situation can be reduced or sometimes completely avoided.

A hall destination floor input device for elevators includes an information input receiver provided on a hall of an elevator on a floor set as an evacuation floor in case of an emergency in a building including the elevator. The information input receiver receives information from outside. The device also includes a signal transmitter that transmits a signal to a control system of the elevator, and a controller configured to cause the signal transmitter to transmit a signal indicating a destination floor of the elevator when the information receiver receives input of information on the destination floor if an operation mode is not an emergency mode based on emergency information of the building, and cause the signal transmitter to transmit a signal to open a door of the elevator on the hall when the information input receiver starts receiving input of information if the operation mode is the emergency mode.
