Device control apparatus, device control method, and device control system

A device control apparatus controls devices. The device control apparatus includes a storage unit, a specification unit, and a control unit. The storage unit stores operational sensor change information in which a controlled device, operation status of the controlled device, and change attribute of the controlled device set based on sensor information obtained by collecting a change in sensor measured value at regular time intervals, are associated with one another. The specification unit specifies a conflicting device that conflicts with the controlled device in the change attribute related to the operation status, based on the operational sensor change information. The control unit controls the specified conflicting device to interpolate the contents of the request so as to eliminate the competition in the operation status between the conflicting device and the controlled device, and then executes the interpolated request.
