Abstract
An abnormality detection device acquires sensor information indicating a state of a person and device information indicating a state of a device, determines whether there is a combination corresponding to the acquired sensor information and acquired device information in a learning database, and determines whether there is sensor information or device information corresponding to the acquired sensor information or the acquired device information in a behavior pattern database. If it is determined that the acquired sensor information is not in a normal range, the device determines that a current state is in the normal state when it is determined that there is the corresponding combination, and determines that the current state is in an abnormal state when it is determined that there is no corresponding combination and no corresponding sensor information or device information.
