Embodiment Construction

[0023] Such as figure 1 As shown, the intelligent sleep monitoring system includes,

[0024] Pressure sensor, air cushion, gas conduit, signal processing circuit, MCU control module, sleeping position adjustment module and alarm rescue module; its

[0025] Using PVCD to collect human analog signals, through the signal processing circuit, the signal is amplified and filtered, and the analog signals collected by PVCD are passed through three-way band-pass filters to separate the signals of heartbeat, respiration and displacement, and their frequencies are 0~ 1HZ, 1~2HZ, 10~15HZ.

[0026] The MCU control module uses HT66F50 as the main control chip. It receives the digital signal obtained through the A / D converter, and processes and diagnoses the obtained signal. If the displacement and shape of the human body change, adjust the sleeping position of the human body in time to improve the breathing condition; if cardiac arrest, sudden death, fall and other symptoms are detected,...

Abstract

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.

Description

technical field [0001] The invention relates to a sleep monitoring system, in particular to a sleep monitoring system with low cost, small contact area and easy operation. Background technique [0002] Medical data shows that night is a period of high incidence of diseases. The incidence of acute myocardial infarction at night accounts for about half of the total incidence of the whole day, and the number of patients with cerebral thrombosis who develop sudden death during sleep is as high as 70% to 80%. In addition, many diseases are also aggravated at night, including cardiac insufficiency, bronchitis, asthma and so on. Especially for elderly and critically ill patients, the probability of onset is higher at night. Most of the detection systems on the market today use bandage or patch sensing, which is not only expensive and not conducive to home detection, but also greatly affects the The sleep quality of the tested person brings greater hidden dangers. Contents of t...
