PROBLEM TO BE SOLVED: To provide a biological information processing system that objectively judges reliability of a RTC provided in a data card and a biological information measurement device, respectively, calibrate the RTC to date/time information on the RTC higher in reliability, and thereby improve reliability of the date/time information accompanied by biological information to be measured.SOLUTION: A time calibration correctness level flag serving as an index for objectively judging correctness of a RTC, and an electronic chart calibration date/time serving as a date and time on which time calibration is conducted with a personal computer are introduced to both of a biological information measurement device and a data card. The time calibration correctness level flag and the electronic chart calibration date/time are used, and thereby, a judgement of whether the RTC of any of the biological information measurement device and the data card is calibrated to the date/time information on other thereof or calibration itself is not conducted can be made by clear standards.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】データカードと生体情報測定装置がそれぞれ備えるRTCの信頼性を客観的に判断し、より信頼性の高いRTCの日時情報に較正することで、測定する生体情報に付随する日時情報の信頼性を向上する、生体情報処理システムを提供する。【解決手段】生体情報測定装置とデータカードの双方に、RTCの正確性を客観的に判断するための指標となる、時刻較正正確度フラグと、パソコンにて時刻較正を行った日時である電カル較正日時を導入した。この時刻較正正確度フラグと電カル較正日時を用いることで、生体情報測定装置とデータカードのどちらのRTCを他方の日時情報に較正するか、または較正自体を行わないのかを明確な基準で判断することができる。【選択図】図1
