Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, several changes and improvements can also be made.These belong to the present invention
Protection scope.
Fig. 1 is the structural schematic diagram of the sleep quality monitoring device provided by the invention based on optical fiber micro-bending pressure sensitive,
As shown in Figure 1, light source 10 connects multimode fibre 11, the micro-bend pressure sensitive array 12 of 11 incoming fiber optic of multimode fibre, optical fiber micro-bending
Pressure sensitive array 12 can choose the mode of structuring the formation of Fig. 2 or Fig. 3, and the fiber-optic output of optical fiber micro-bending pressure sensitive array 12 will
Light wave is sent into photodetector and signal processing circuit 13 and carries out data processing.When head pressure point changes, multimode fibre wink
Between incude, optical fiber bends loss.
Specifically, it structures the formation as shown in Fig. 2, carrying out two dimension to anamorphoser, may then pass through the change on adjustment unit area
Shape device number or the modulation depth for changing equally distributed anamorphoser, so that the number of the anamorphoser in sensitive zones on unit area
Change of gradient is presented in the modulation depth of mesh or anamorphoser.
Specifically, as shown in figure 3, pillow is divided into three isolated areas, for laying anamorphoser.In order to facilitate differentiation,
The fibre loss state of three isolated areas can be encoded.
Referring to fig. 2, Fig. 3 in the specific implementation can be by a root multimode fiber with the snakelike deformation for passing around special laying
Device array, or three independent multimode fibres were passed around to the anamorphoser array in three regions respectively.
For the arrangement in Fig. 2, light source can be set and connect with multimode fibre one end by FC optical fiber connector, multimode
The other end of optical fiber is connect by photodetector with signal processing circuit.
For the arrangement in Fig. 3, light source can be set after the fiber optic splitter of 1*3, respectively with every multimode
One end of optical fiber is connected, and the other end of three root multimode fibers passes through photodetector respectively and connect with signal processing circuit.
Specifically, when head pressure point changes, multimode fibre moment induction, optical fiber bends loss, the light in Fig. 2
As head pressure point changes significant change can occur for light loss numerical value in fibre, when the big Mr. Yu's setting value of the difference of loss value, meter
The meeting stored counts of number device is simultaneously shown.Similar principle, light loss numerical value can change with head pressure point in three optical fiber in Fig. 3
And different states is presented.By being encoded to three regions, it can count and show according to code change.
Since as head pressure point changes significant change can occur for light loss numerical value in optical fiber, the difference of loss value is greater than
When certain setting value, counter meeting stored count realizes the duration of record sleep in real time, from bed number, sleep period.
In a kind of optional embodiment, APP real-time display dormant data can also be passed through.
It should be noted that different spacing ginsengs can also be arranged in anamorphoser other than the arrangement mode in Fig. 2, Fig. 3
Several and modulation depth parameter.When anamorphoser subregion is laid, arbitrary shape can be set as with cloth.
In a kind of optional embodiment, anamorphoser is toughness material, can be arbitrary shape and construction.Light source, spy
It surveys device and signal processing circuit is closed by radiation proof material.
Inductor is placed in pillow by the present invention, is formed and is rested the head on integrated Intelligent pillow, it is not only used to sleep, have simultaneously
There is the function of monitoring sleep quality, it is very practical for the people there are sleeping problems, during sleep at night, do not have to wearing monitoring
Product, it is very convenient.It is a kind of non-wearable household sleep monitor, by detection head dynamic, can be recorded in real time
Sleep duration, from bed number, sleep period, individualized intelligent analysis and excitation for sleep improve.It is recorded in real time by APP
Sleep big data, understand the sleep quality of oneself, escort for the healthy sleep of user.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
