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,...
