Long-time sitting dozing reminder for old people

Abstract

The invention discloses a long-time sitting dozing reminder for old people. A plurality of voltage controlled switches are arranged inside a chair cushion, and a plurality of iron sheets are evenly distributed in a lap belt in the length direction. An electromagnet is arranged at the position, close to the waist of old people, inside a chair backrest, and a pulse sensor is worn on the wrist of old people. A movable writing board is provided with an eye closing monitoring module and a flashlight, and a vibrator and a heating resistor are arranged below the voltage controlled switches. The voltage controlled switches are triggered, a single chip microcomputer starts timing, when signal sustained input time exceeds a set time, a buzzer module gives out a reminding sound, the electromagnet is powered up, and the lap belt and the electromagnet are attracted to enable old people to be constrained on the chair backrest; after 30 seconds, if old people still do not leave a chair, the vibrator can vibrate; after another 30 seconds, if old people still do not stand up, the heating resistor and the flashlight are powered up at the same time, and when old people doze, the eye closing monitoring module is triggered to input signals to the single chip microcomputer. By means of the long-time sitting dozing reminder for old people, whether old people sit for a long time or doze can be judged, the reminding modes are diversified, and the purpose for protecting old people is achieved.
