LIFE PATTERN ANALYSIS AND ENUNCIATION SYSTEM

摘要

PURPOSE:To analyze the life pattern and living condition from the way an electric apparatus is used for selt-checking of changes and abnormality of life of a high-aged person and for protection by an external organization. CONSTITUTION:A current detecting section 31 is mounted on an electric wire and an output thereof is inputted into an analyzer 3 having a communication interface 38 from a pretreatment section 32. The analyzer 3 possesses data of reference power spectrum of consumed current corresponding to apparatuses in a memory. A current signal is digitized with a pretreatment section 32 and undergoes a fast Fourier transform with a processor 9 to make an extraction power spectrum. The spectra are compared with the reference power spectrum and when the reference power spectrum of a specified apparatus is contained in an extraction power spectrum, the use of the apparatus is stored into a memory together with time. The results are displayed on an output section 36 at any time to be sent to an external organization through a communication circuit 37. This enables self-checking of living condition and rhythms from the way an electric appratus is used and thus, life information can be transmitted to the external organization with the communication circuit.
