The invention relates to a method for managing usage data of an elevator system (100) operating in a construction time use (CTU) mode. The method comprises: operating (210) the elevator system (100) in the CTU mode, obtaining (220) statistical usage data of the elevator system (100), comparing (230) the obtained statistical usage data to reference data, detecting (240) that the obtained statistical usage data deviates at least partly from the reference data, and generating (250) at least one control signal comprising an indication of the detected deviation to at least one operator system (114) in response to the detection of the deviation. The invention relates also to a computing unit (112) and an elevator system (100) for managing usage data of an elevator system (100),

An elevator operating device for inputting a travel request on a floor of a building has a touch-sensitive screen system, which has a screen region that is visible to a passenger, and a central control device. The central control device controls the screen system in a first mode, to display a first graphical user interface, and in a second mode, to display a second graphical user interface. The first graphical user interface comprises one or two travel direction symbols. The second graphical user interface comprises an edge zone for symbolizing a waiting time until the elevator car arrives on the floor, and a center zone for symbolizing an occupancy of the elevator car by passengers, wherein a displayed degree of filling of the center zone symbolizes an occupancy of the elevator car.

A method of taking an elevator by an unmanned device is provided including: through a remote communication connection established with a cloud platform, sending a start floor elevator call request to the cloud platform; receiving real-time running information of at least one elevator returned by the cloud platform; selecting a target elevator according to the real-time running information of the at least one elevator, and entering the target elevator; and establishing a communication connection with an elevator controlling communication device of the target elevator, and sending a target floor elevator call request to an elevator controlling device of the target elevator through the communication connection such that the elevator controlling device controls the target elevator to run to a target floor based on the target floor elevator call request, where the elevator controlling communication device of the target elevator is connected with the elevator controlling device of the target elevator. Further, an elevator controlling method, an elevator scheduling method, an unmanned device, an elevator controlling device, an elevator scheduling cloud platform and a system for taking an elevator by an unmanned device are provided.

A method of calling an elevator car for an elevator system including: transmitting, using a first beacon, a first poll wireless signal, the first poll wireless signal having a first poll transmission speed; receiving, using the first beacon, a first response wireless signal from a passenger mobile device in response to the first poll wireless signal, the first response wireless signal having a first response transmission speed; determining a first time of flight between transmission of the first poll wireless signal from the first beacon and receipt of the first response wireless signal at the first beacon; calculating a first distance between the first beacon and the passenger mobile device based on the first time of flight, the first poll transmission speed, and the first response transmission speed; and determining a location of the passenger mobile device based on at least the first distance.

An elevator security system for a building includes data relating to a floor that a user may access in the building, a device in which the data is stored, a credential containing the data in a machine readable format and created by the user, and a first machine reader reading the credential and sending data therein to the device for querying whether the user may access the floor, the device allowing access to an elevator car for transport to the floor if the credential is in sync with the data stored in the device.

An elevator security procedure is performed according to a security level of an elevator of a building including a plurality of residence units through an elevator security system. The elevator security system includes home gateways respectively installed at the plurality of residence units and a server coupled to the home gateways. The server may analyze a comparison result of passenger information of passengers in the elevator and member information of members of residence units associated with floors selected by the passengers in the elevator. The server may determine a security level of the elevator based on the analysis result. The server may perform a security procedure designated for the determined security level by controlling at least one of constituent elements of the elevator and smart devices coupled to the at least one of home gateways.

A lift system for moving a car along a track in a guided manner. The lift system having a guide rail system, a car and a drive unit arranged on the car. The guide rail system forms a closed track along which the car can be moved between floors when in operation. The drive unit has a motor, a gear wheel system connected to the motor by a shaft and a guide disk. The guide rail system has a pinion system and guide edges spaced apart from one another, which cooperate with the guide disk. When in operation, the motor drives the gear wheel system and the gear wheel system acts on the pinion system in order to move the car along the track in a guided manner.

Disclosed is a car mover, configured for autonomously moving an elevator car along a track beam in a hoistway lane, having: a car mover body; a drive wheel operationally connected a lateral side of the car mover body, and configured to rotate about a drive wheel axis; a first guide wheel operationally connected to the lateral side of the car mover body, wherein the first guide wheel is offset from the drive wheel so that, in operation: the first guide wheel engages a lateral sidewall of the track beam when the drive wheel laterally moves on the track beam, to thereby restrict lateral motion of the drive wheel on the track beam.

An elevator calling operation based on a wrist-wearable smart device. An elevator calling operation system of the present invention comprises: an elevator control apparatus, and a wrist-wearable smart device wirelessly connected to the elevator control apparatus, wherein the wrist-wearable smart device comprises an identity identification module which stores identity identification information about a passenger, and a motion sensor which is used for acquiring elevator calling motion information about the passenger performing an elevator calling operation, and the wrist-wearable smart device transmits the elevator calling motion information, in association with the identity identification information, to the elevator control apparatus; and the elevator control apparatus comprises: a passenger identity recognition module and an elevator calling operation recognition module, the elevator calling operation recognition module used for recognizing the elevator calling operation of the passenger according to the elevator calling motion information from the motion sensor.

An information processing apparatus includes a controller configured to predict a state of congestion of an elevator installed in a building and generate, based on the predicted state of congestion, a proposal message to propose a departure time for the building to a user planning to travel to the building.
