  • Publication number: 20230207114
    Abstract: A biological information analysis system includes a data reception unit that receives time-series data of biological information from a sensor terminal that acquires biological information, a storage unit that stores the received time-series data, a first representative value acquisition unit that acquires a first representative value based on data in a predetermined period among the received time-series data, and a second representative value acquisition unit that acquires a second representative value based on a plurality of first representative values consecutive on a time axis. In a case where an error occurs in communication between the data reception unit and the sensor terminal and a predetermined condition is satisfied, the first representative value acquisition unit uses pre-error time-series data transmitted before the error occurs and stored in the storage unit and post-error time-series data transmitted from the sensor terminal after the error occurs, to acquire the first representative value.
