Embodiment Construction

[0021] Such as figure 1 As shown, the intelligent sleep monitoring system includes,

[0022] Pressure sensor, air cushion, gas conduit, signal processing circuit, MCU control module, sleeping position adjustment module and alarm rescue module; its

[0023] 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.

[0024] 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, which is composed of a physiological signal acquisition module, an MCU control module, a power supply module, a sleeping posture adjustment module and an alarm rescue module. Among them, the physiological signal acquisition module uses an air cushion to balance the force generated by the myocardial contraction, chest contraction and other muscle movements during respiration, and converts physiological signals such as human respiration, heart rate, and displacement into electrical signals through pressure sensors. After filtering and amplifying, it is sent to the MCU for processing to determine whether there are abnormalities such as sleep apnea termination, cardiac arrest, and falling. sound and light alarm. The invention has a small contact area with the measured body, does not need to wear sensors, does not affect sleep, has low cost, and is convenient for operation and maintenance management. A sleep monitoring system that can be used for daily home monitoring of old and young.

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 throughout the 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 ...
