Intelligent sleep monitoring system

The invention discloses an intelligent sleep monitoring system with a small contact surface. The intelligent sleep monitoring system consists of a physiological signal acquisition module, a micro control unit (MCU) control module, a power module, a sleeping posture adjustment module and an alarm and rescue module, wherein the physiological signal acquisition module balances the generated force due to myocardial contraction, chest contraction in the respiration process and other muscular movements in the lying process by adopting an air cushion, the body respiration, heart rate, displacement and other physiological signals are converted into electric signals through a pressure sensor, the electric signals are filtered and amplified and are transmitted to the MCU for processing and judging whether the abnormalities of sleep apnea, sudden cardiac arrest, drop and the like occur; when the abnormality is detected, the MCU drives a stepping motor, so that the pillow is deformed, the sleep respiration is adjusted, and corresponding audible and visual alarm is performed aiming at the abnormality. The contact area between the system and a measured body is small, a sensor is not required to be worn, the sleep is not influenced, the cost is low, and the operation, maintenance and management are convenient. The system can be used for a sleep monitoring system for performing daily household monitoring on young and old people.
