[0004] The purpose of the present invention is to be achieved through the following technical solutions:

[0005] A sleep instrument for real-time monitoring of human sleep status comprises a power supply, a sensor, an amplifying circuit module, a DSP (digital signal processing) data processing module, a control module, a wireless module and a data storage module.

[0009] The above-mentioned monitoring method of the sleep instrument for monitoring the sleep state of a human body comprises the following steps:

[0010] (1) Information collection of sleep status:

[0011] The sleep status information is collected through a PVDF pressure tube. The sleep status information includes pulse beats, breathing times (including deep breathing times and shallow breathing times), and body movements. The collected information is then converted into electrical signals through a piezoelectric conversion module.

[0012] (2) Amplification and filtering of collected signals:

[0013] The electrical signal converted by the piezoelectric conversion module is amplified by the amplifier module and filtered by the filter element, and then sent to the DSP data processing module for further analysis and processing.

[0031] like Figure 1-9 As shown, a sleep instrument for real-time monitoring of human sleep status according to an embodiment of the present invention comprises a power supply 1, a sensor 2, an amplifying circuit module 3, a DSP data processing module 4, a control module 5, a wireless module 6 and a data storage module 7. The sensor 2, the amplifying circuit module 3, the DSP data processing module 4 and the control module 5 are connected in sequence according to corresponding input and output ports. The DSP data processing module 4 analyzes and processes the data information of the pulse beats, the breathing times and the body movement times collected by the sensor 2. The corresponding ports of the control module 5 are respectively connected to the wireless module 6 and the data storage module 7. The wireless module 6 sends the processed data information to the computer for analysis, so as to realize data storage. The image is converted and displayed, and the data storage module 7 stores the processing information sent by the DSP data processing module 4; the sensor 2 is provided with a PVDF pressure tube 8, and the PVDF pressure tube 8 is arranged in a sinusoidal wave in the sensor 2. The distribution of the sinusoidal waveform can enable the PVDF pressure tube 8 to collect sleep information in a larger range, and the head end of the PVDF pressure tube 8 is connected to a piezoelectric conversion module 9, and the piezoelectric conversion module 9 converts the pressure signal collected by the PVDF pressure tube 8 into an electrical signal. The piezoelectric conversion module 9 is connected to a four-core plug 11 through a connecting line 10, and the four jacks of the four-core plug 11 have the following functions: +5V, piezoelectric signal output, GND and shielding line.

[0032] The PVDF pressure tube 8 is clamped and fixed by the upper fixing plate 12 and the lower fixing plate 13, and the adhesive sponge 14 is used at the bend to keep the PVDF pressure tube 8 fixed. The upper fixing plate 12 and the lower fixing plate 13 are both soft plates. The use of softer plates is conducive to increasing the sensitivity of the sensor 2, and is also conducive to avoiding external interference and ensuring the stability of the sensor. The ends of the PVDF pressure tube 8 are clamped and pressed by the upper fixing plate 12 and the lower fixing plate 13 that cooperate with each other, which is conducive to the piezoelectric conversion module to sensitively detect the change of the signal and ensure the sensitivity of the sensor. The left and right ends of the upper fixing plate 12 and the lower fixing plate 13 are fixed with fixed plastic 15 to fix and protect the PVDF pressure tube 8.

[0033] When in use, place the sleep instrument just below the pillow and turn on the power supply 1.

[0034] When working, the piezoelectric conversion module 9 converts the pulse beats, breathing times and body movements collected by the sensor 2 into electrical signals, and transmits them to the front end of the amplifier circuit module 3. The output signal of the amplifier circuit module 3 is given to the DSP data processing module 4 for data processing.

[0035] Through the coordination of the control module 5 , the collected information is sent to the computer for analysis through the wireless module 6 , so as to realize the conversion from data to image and display it, and at the same time, the information is stored in the data storage module 7 .

[0036] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
