According to one or more embodiments, a system and method for authorizing a user securing an elevator call in a building is provided. For example, the method includes receiving, at a mobile device, a secure authorization token that includes an expiration time, connecting the mobile device to a backend system using the secure authorization token from the mobile device, verifying, using the backend system, an authenticity of the secure authorization token from the mobile device based on at least the expiration time, generating, at the backend system, a secure access token and a random number in response to the authenticity of the secure authorization token being verified, and receiving, at the mobile device, the secure access token and the random number for use making elevator call requests.

An elevator system configured to determine and transmit an estimated elevator boarding time to a mobile call input device, wherein the boarding time includes the arrival time of the elevator car based on a registered target floor registration information and the duration of time to place the elevator car door and the hoistway door in a fully open state.

A building management robot includes a communication unit configured to recognize an identification device corresponding to a first divided space among at least one divided space in a building and acquire first identification information of the first divided space from the identification device, a camera configured to acquire image data including a position where the identification device is recognized, and a processor configured to recognize a user from the image data, confirm an authentication level of the first divided space of the recognized user from a database, and provide the user with a service based on the confirmed authentication level.

An exemplary elevator destination entry system includes a passenger interface device that presents a visual representation of at least one item that will accompany a passenger on an elevator car. The passenger interface allows the passenger to select the visual representation. A controller is configured to receive indications of passenger requests for elevator service and an indication from the passenger interface device regarding a selected visual representation. The controller determines an amount of space within an elevator car required to accommodate the item based on predetermined space information corresponding to the selected visual representation. The controller assigns a car to a passenger request based on a determination that the assigned car will have adequate space to accommodate the passenger and the item.

An elevator car location sensing system includes at least one first barometric pressure sensor disposed at a sensor position. The first barometric pressure sensor is configured to measure at least one first barometric pressure at the sensor position. An elevator control module is configured to electrically communicate with at least one mobile terminal device that is movable among a plurality of different altitudes. The elevator control module receives a second barometric pressure from the mobile terminal device located at a current altitude, and determines the current altitude based on a comparison between the first barometric pressure and the second barometric pressure.

A system includes an elevator system including an elevator car. The system also includes a control system configured to receive a crowd reduction indicator, determine an elevator car load reduction for the elevator car based on the crowd reduction indicator, adjust an elevator car load limit based on the elevator car load reduction, and trigger a mitigation action in the elevator system based on detecting a condition that exceeds the elevator car load limit.

According to one embodiment, an autonomous mobile robot includes a communication device, a memory, and a hardware processor connected to the communication device and the memory. The communication device receives list information indicating ride conditions of a car from the elevator control system when transmitting a car call message to an elevator control system on a hall of any floor. The hardware processor includes a ride determination unit and a movement control unit. The ride determination unit determines whether the robot is able to ride in the car or not, based on the list information when the car arrives. The movement control unit allows the robot to ride in the car and move to a destination floor when the robot is able to ride.

An aspect of an elevator system includes receiving, from a user, a destination selection and assigning to the user a first elevator and notifying the user of the assignment. The user is detected in a second elevator, and the second elevator is controlled to travel to the destination selected by the user based on detecting the user in the second elevator.

An access control system receives a device-specific identifier of a mobile electronic device. A memory device stores the identifier as belonging to a user present in a public zone. An image processing device generates from a camera image produced by a camera a real-time template for facial features of the user present when the user present requests access to an access-restricted zone, and searches user profiles stored in a database for a reference template that matches the real-time template to a specified degree, wherein a user profile is searched only if it is assigned to a present user based on a stored identifier, wherein in the case of a match, the system grants the user access to the access-restricted zone and denies access when there is no match.

A lift system comprises a call input device and at least one touchscreen for inputting a call for a lift. The touchscreen has at least one functional identifier. When a functional identifier is touched, at least one input signal is generated. The call input device converts into a special input mode for a time-specific or location-specific generation of several input signals.
