The present invention includes: a first divider that divides time series data measured at a normal time into periodic data in period units; a reference data generator that generates reference data based on a plurality of pieces of periodic data; an allowable error calculator that calculates an allowable error of a divergence value, based on the time series data of the normal time and the reference data the divergence value indicates a degree of divergence from the reference data; a divergence value calculator that calculates a divergence value between time series data for detection, the time series data for detection is a detection object for detection of a non-normal state; and a detector that detects the non-normal state in accordance with whether or not the divergence value is within a range of allowable errors.

Lift communications systems, wall-mounted controls, and methods of using and configuring the same are disclosed. A lift communications system includes one or more lifts, each one of the one or more lifts is movable within a space. The lift communications system further includes a wall-mounted control coupled to a wall of the space. The wall-mounted control is configured to communicatively couple to the one or more lifts via a wireless connection. When the wall-mounted control is communicatively coupled to a lift of the one or more lifts, the wall-mounted control is configured to direct operation of the lift and receive data from the lift.

The disclosure herein includes a method for controlling elevators by an intelligent building system. The method includes receiving, by the intelligent building system, elevator calls initiated by passengers. Each elevator call can include a passenger identification corresponding to a passenger initiating the elevator call. The method further includes procuring passenger preference information based on the passenger identifications in response to the elevator calls and grouping the passengers with respect to the passenger preference information to produce passenger groups. The method further includes controlling the elevators to collect the passenger groups.

An elevator system is provided. The system comprises a first acquisition unit that acquires an image in a car of an elevator and an image of a landing of the elevator; a first generation unit that generates first learning data from the acquired images; a learning unit that performs learning using the first learning data, thereby generating a first learned model; a second generation unit that generates input data from a new image; an estimation unit that estimates, by applying the input data to the first learned model, whether the person on the landing of the elevator, which is included in the new image, gets in the elevator; and a control unit that controls an operation of the elevator based on an estimation result.
