US Patent 11928334 Apparatus controller and apparatus control system

An apparatus controller includes a first communication module, a storage module, a data processing module, and a controller. The first communication module receives from each of one or more apparatuses, operation information indicating the operation state of the apparatus. The storage module stores the operation information in a cumulative manner. The data processing module combines, when values indicated by a plurality of operation information pieces successively received from the apparatus by the first communication module are equal to each other, the plurality of operation information pieces, thereby producing combined operation information. The controller causes, when the data processing module produces the combined operation information, the storage module to store the combined operation information instead of the plurality of operation information pieces.
