Elevator systems and methods are provided. The systems include an elevator car including an elevator car door interlock device operable to open and close elevator car doors and a plurality of landing doors located at landings, each landing door including a landing door interlock device operable to open and close a respective landing door. Each landing door interlock device is engageable by the elevator car door interlock device to operate the elevator doors. An elevator component inspection system having a detector to monitor the interlock devices obtains inspection data associated with the interlock devices. A control unit is configured to analyze the inspection data. The component inspection system captures images of the interlock devices using the detector, performs a database inquiry comparing the captured image against a database of interlock device states, and determines a state of the interlock devices.

Disclosed are a robot system and an operation method thereof. The robot system includes a central controller, a robot configured to communication with the central controller and capable of autonomous driving, and a first sensing module configured to communicate with the central controller, to be mounted inside an elevator, and configured to measure an electric power of a communication radio wave emitted by a mobile communication device inside the elevator. The robot may transmit or receive a wireless signal on a mobile communication network established according to 5G communication.

An elevator preventive maintenance system capable of helping, when an abnormality of an elevator is predicted to occur, a concerned person needing no countermeasure information to grasp information quickly and easily, and helping a concerned person needing countermeasure information to react to the abnormality quickly and precisely. The system includes: a prediction section configured to predict an abnormality of an elevator to occur, based on abnormality prediction information; a storage section configured to pre-store concerned person information relating to the elevator; a communication section configured to transmit abnormality occurrence prediction information to concerned person in the case the abnormality is predicted to occur.

Elevator systems and methods of use including an elevator car located within an elevator shaft, at least one sensing device arranged within the elevator car, an elevator controller arranged to control at least one of an operating condition and at least one feature within the elevator car, and a computing system in communication with the at least one sensing device and the elevator controller, wherein the computing system is arranged to detect a passenger state of a passenger within the elevator car and configured to control the operating conditions and features within the elevator car based on the detected passenger state.

Systems and methods for protecting autonomous mobile machine tailgating may include an elevator control system that receives, from an autonomous mobile machine, an request signal requesting access by the autonomous mobile machine to a restricted floor of a facility. The elevator control system may also determine a presence of an individual in an elevator with the autonomous mobile machine. The elevator control system may perform a tailgate prevention operation to prevent an unauthorized access of the individual to the restricted floor by following the autonomous mobile machine. The elevator control system may also provide access for the autonomous mobile machine to exit the elevator at the restricted floor, in response to the tailgate prevention operation being performed.

Methods, systems, and devices for monitoring air quality and controlling air purification in an environment are described herein. The method can include receiving from a device a plurality of air quality parameters for the environment and receiving an indication representing a potential change in occupancy in the environment. In response to the indication of a potential change in occupancy, the method can include determining an air quality target that is based at least in part on at least one air quality parameter in the plurality of air quality parameters and the potential change in occupancy. The air quality parameter can be representative of the quality of air to be achieved in the environment for the change in occupancy. The method can include transmitting instructions to control purification in the environment based at least in part on the air quality target.

A conveyance system includes a transmitter configured to generate a signal; a receiver configured to receive the signal; the transmitter and receiver located so that the signal passes through a passenger area of the conveyance system; a controller configured to receive a signal strength of the signal received at the receiver; the controller configured to determine a loading factor in the passenger area in response to the signal received at the receiver.

An elevator device according to this disclosure includes a detection device, an identification module, and a determination module. The detection device is provided to a car of an elevator, and detects detection information. The identification module repeatedly acquires identification information for identifying a passenger from the detection information detected by the detection device. The determination module determines a leaving floor of the passenger based on a change in the identification information acquired by the identification module and a floor on which the car stops.

The present invention relates to a method of highly efficiently operating an elevator by analyzing an operation of the elevator, including: a base information collecting step of measuring and collecting information on a change over time in magnitudes of current values of a driving unit when the driving unit for moving the elevator upward or downward moves the elevator upward in a normal state, measuring and collecting information on a change over time in magnitudes of current values of the driving unit when moving the elevator downward, classifying the measured information into driving information of the driving unit when moving the elevator upward and driving information of the driving unit when moving the elevator downward, and storing the driving information of the driving unit when moving the elevator upward and the driving information of the driving unit when moving the elevator downward as base information of the driving unit.

A method for detecting an entry into an elevator car of an elevator system by a passenger uses a mobile device carried by the passenger. The mobile device has at least one, but in particular a plurality of sensors, with which the mobile device detects and evaluates measured values. An entry into the elevator car is then detected on the basis of comparing the measured values with at least one stored signal pattern.
