  • the main force point changes, such as the previous main force pressure sensor number (1, 2, 3)
  • the current main force pressure sensor number is (2, 3, 4). ⁇ , then it is judged that a turn over occurs, and the number of turns is increased by one.
  • Step S304 The display terminal performs statistics according to the received sleep data, and obtains a sleep length and wakes up. Long, shallow sleep, long sleep and deep sleep.
  • the display terminal After receiving the sleep data, the display terminal performs statistical calculation according to the sleep state and the sleep internodes of each state, and obtains the sleep length (ie, the length of the sleep state), the awake length (ie, the length of the waking up), Shallow sleep, long sleep and deep sleep.
  • the sleep length ie, the length of the sleep state
  • the awake length ie, the length of the waking up
  • Shallow sleep long sleep and deep sleep.
  • Step S305 The display terminal outputs a sleep state statistical graph and/or a sleep quality report according to the sleep length, the awake length, the light sleep length, and the deep sleep length.
  • the display terminal outputs a sleep state statistical graph after calculating the sleep length, the awake length, the light sleep length, and the deep sleep length.
  • the sleep state chart is a histogram including sleep length, awake length, light sleep length, and deep sleep length. According to the demand, it is also possible to perform sleep quality analysis based on sleep length and output a report on the quality of sleep.
  • the Bluetooth controller can send the heart rate and the sleep data to the intelligent terminal device for display, thereby providing a basis for the user.
  • the embodiment of the invention performs analysis and processing through the Bluetooth controller and the display terminal, and the heart rate sleep data obtained through the electrocardiogram data and the pressure data is more accurate, can provide an effective reference basis for the user, and is simple and convenient to operate.

Abstract

L'invention concerne un système et un procédé de surveillance du rythme cardiaque et du sommeil. Le système comprend : un matelas de lit intelligent (1) et un terminal d'affichage (5). Le matelas de lit intelligent (1) est doté de capteurs (2, 3) et d'un dispositif de commande Bluetooth (4). Les capteurs (2, 3) sont utilisés pour recueillir des données d'informations de corps humain. Le dispositif de commande Bluetooth (4) acquiert les données d'informations sur le corps humain collectées par les capteurs (2, 3), génère, sur la base des données d'informations de corps humain, des données de rythme cardiaque et de sommeil, et transmet les données générées au terminal d'affichage (4). Le procédé de la présente invention permet de surveiller le rythme cardiaque et la qualité du sommeil d'un utilisateur en recueillant, en analysant et en traitant des données d'informations de corps humain. L'invention permet à l'utilisateur de surveiller le rythme cardiaque et l'état du sommeil personnels, de réaliser des réglages pertinents et de maintenir une bonne santé.
