Description

Manufacturing method of sleeping mat for sensing sleeping status

The present invention relates to a method of manufacturing a mat for detecting a sleep state, and more particularly, to a method for manufacturing a mat for detecting a sleep state that detects and analyzes a biosignal of a sleeping person to determine the sleep state of the sleeper.

In general, human sleep is an important action for recovering the mental and physical fatigue accumulated during daily life, and the deeper the sleep, the faster the recovery of the cover, so the demand and research for deep sleep is being actively made.

Sleep can be divided into several stages according to its depth, and the most widely used is divided into REM (rapid eye movement) sleep, which is relatively shallow sleep, and non-REM sleep (or non-REM sleep), which is relatively deep sleep. Non-REM sleep is further divided into deep sleep and light sleep using a certain reference value.

In addition, since human activity continues even during sleep, the heart beats and breathing takes place. Heart rate per minute and respiratory rate per minute during sleep are also indicators of a healthy sleep.

In other words, for healthy sleep, the ratio of deep sleep such as non-REM sleep must be high, and heart rate per minute and respiration per minute must be stable. For example, if your breathing rate is low, you might suspect sleep apnea.

In this regard, in the related art, a sleep state detection mat system has been proposed in Korean Patent Registration No. 10-0867103.

In the conventional Korean Patent Registration No. 10-0867103, a pressure sensor evenly arranged on a sleeping mat, and sensing data from the pressure sensor are collected, and the mat using a node position of each pressure sensor and each sensing data. Sleep state detection, comprising: a gateway device for detecting a pressure distribution applied to the A mat system is disclosed.

However, in the sleep state detection mat system disclosed in the prior art, the pressure sensors are evenly arranged on the sleeping mat. In order to accurately detect the sleep state, a plurality of pressure sensors are evenly and horizontally arranged on the entire area of the sleeping mat. Since it is inefficient and unproductive, there is a problem with many difficulties in commercialization.

Accordingly, in describing the present invention, detailed descriptions of related known technologies that may unnecessarily obscure the gist of the present invention will be omitted.

1 to 6 are views showing the configuration of a mat for detecting a sleep state and first and second sensor units configured therein according to the present invention.

The mat 100 for detecting a sleep state according to the present invention is, as shown in FIG. 1 , between the upper and lower shells 110 and both shells 110 forming the top and bottom surfaces of the mat 100 , respectively. The first and second sensor units 130 and 140, the first and second sensor units 130 and 140, which are provided to be stacked between the upper and lower cushioning materials 120, both cushioning materials 120, and Including the electrically connected controller 150, it is configured to detect the sleep state through the movement of the sleeper.

In particular, the first sensor unit 130 as described above includes a nonwoven fabric 130-1 that can be freely bent and unfolded, and a plurality of sensor wires 130a, ..., 130n installed on the nonwoven fabric 130-1. .

The non-woven fabric 130-1 is formed of a flame-retardant non-woven fabric in which flame-retardant yarns are produced through a needle punching or a calendering process, so that it can have an effect of preventing a fire.

And, this nonwoven fabric 130-1 is provided to be embedded in the mat 100 while maintaining a certain distance from the surface of the mat 100, that is, the outer shell 110 by the cushioning material 120 provided on the upper and lower surfaces. .

Meanwhile, as shown in FIG. 2, the sensor wires 130a, ..., 130n on the nonwoven fabric 130-1 divide the entire surface of the nonwoven fabric 130-1 into several sections (regions) as independent lines. will be compartmentalized.

That is, each sensor wire (130a, ..., 130n) is provided to be arranged spaced apart at regular intervals in a zigzag form on the nonwoven fabric 130-1, the adjacent lines of the sensor wires (130a, ..., 130n) The ends are bent in a gentle arc shape and are connected in a changed state, and the distal ends of each of the sensor wires 130a, ..., 130n are electrically connected to the controller 150 and provided.

At this time, each sensor wire (130a, ..., 130n) is, as shown in Figs. 4 and 5, by the thread 160 sewn by the stitching method on the nonwoven fabric 130-1 by the stitch (Stitch) method. fixedly provided.

In particular, in the thread 160 sewn by stitching by the stitch method, one needle passes through the nonwoven fabric 130-1 up and down while alternately on the left and right sides of the sensor wires 130a, ..., 130n to continuously produce sweat. In the upper surface of the nonwoven fabric 130-1, the upper thread 161 is formed by moving the left and right sides of the sensor wires 130a, ..., 130n in a zigzag fashion, and the lower thread 162 is a nonwoven fabric ( 130-1) is formed in the form of an oblique line.

At this time, the distance between the left and right both ends of the upper thread 161 crossing the sensor wires 130a, ..., 130n and the sensor wires 130a, ..., 130n is provided to maintain a distance of 5 mm or more, respectively. Preferably, this is to ensure the fluidity of the sensor wires (130a, ..., 130n) by the load acting when the sleeping person is lying on the mat 100. In addition, when the load acting on the mat 100 is removed, it is possible to secure the fluidity of the sensor wires 130a, ..., 130n to be returned to their original positions.

When power is applied to the sensor wires 130a, ..., 130n provided in this way by the controller 150, an electromagnetic field of a certain wavelength is generated between adjacent lines of each sensor wire 130a, ..., 130n-1. This works, and when a position (height) difference is generated between the lines of each of the sensor lines 130a, ..., 130n, the waveform of the electromagnetic field applied between the two lines is changed.

Accordingly, in the present invention, the sleep state is analyzed by detecting the sleeper's biosignal through the change in the waveform of the electromagnetic field generated from each of the sensor lines 130a, ..., 130n.

On the other hand, the sensor wires (130a, ..., 130n) as described above are divided into several areas so as to detect body parts such as the head, chest, abdomen, buttocks (waist), thighs, etc. of the sleeping person, respectively, and are installed, In this way, the load acting according to the body part of the sleeping person is applied differently to each of the sensor lines 130a, ..., 130n dividing the mat 100 into several sections (regions), and accordingly, the mat 100 Changes in the wavelength of the electromagnetic field generated by each sensor line 130a, ..., 130n provided in each area of the each can be detected.

That is, each of the sensor wires 130a, ..., 130n of the first sensor unit 130 is normally located on the same plane, so that an electromagnetic field of a certain wavelength acts between the sensor wires 130a, ..., 130n. When the sleeping person lies on the mat, each sensor wire 130a, ..., 130n is pressed with different force depending on the body part of the sleeper, so that the height of each sensor wire 130a, ..., 130n is different, In each of the sensor lines 130a, ..., 130n, a change in wavelength of an electromagnetic field different from each other is generated and output due to a height difference.

At this time, the height of each of the sensor wires 130a, ..., 130n can be easily changed by the spaced distance from the upper thread 161 .

Accordingly, the controller 150 compares and determines the wavelength information of the electromagnetic field, that is, the change width of the wavelength, collected from each of the sensor lines 130a, ..., 130n, with the reference information to determine the sleeper's biosignals (ie, heartbeat pattern, pulse pattern). , breathing pattern, sleeping posture, tossing and turning) to analyze and judge the health status.

The second sensor unit 140 includes a nonwoven fabric 140-1 that can be freely bent and unfolded, and a plurality of piezoelectric wires 140a and 140b installed on the nonwoven fabric 140-1.

As in the first sensor unit 130, the nonwoven fabric 140-1 has the advantage of preventing fire by being formed of a flame-retardant nonwoven fabric in which the flame-retardant yarn is produced through a needle punching or calendering process, and its upper and lower surfaces It is provided to be embedded in the mat 100 while maintaining a predetermined distance from the outer shell 110 constituting the surface of the mat 100 by the cushioning material 120 provided in the .

Two types of piezoelectric wires 140a and 140b are respectively provided on the nonwoven fabric 140-1. As shown in FIG. 3 , these two types of piezoelectric wires 140a and 140b include horizontal piezoelectric wires 140a installed in the horizontal direction on the nonwoven fabric 140-1 and vertical piezoelectric wires installed in the vertical direction. (140b) is provided.

The horizontal piezoelectric wire 140a is installed side by side in a state in which a plurality of lines are maintained at regular intervals in the left and right width directions of the nonwoven fabric 140-1, and the vertical piezoelectric wire 140b includes a plurality of lines in the nonwoven fabric 140-1. ) are installed side by side while maintaining a certain distance in the vertical and longitudinal direction.

As a result, an intersection 141 intersecting each other is formed between the horizontal piezoelectric wire 140a and the vertical piezoelectric wire 140b, and the area around the intersection 141 including the intersection 141, that is, an angle to be described later An area up to and including the bent portion 142 of the line is referred to as an intersecting area, and adjacent intersecting areas are provided so as not to invade each other.

On the other hand, the piezoelectric wires 140a and 140b as described above are sewn on the nonwoven fabric 140-1 by a stitch method as in FIGS. 4 and 5 as in the first sensor unit 130 . It is provided to be fixed by the seal (160).

At this time, the thread 160 sewn by the stitching method passes through the nonwoven fabric 130-1 alternately on both left and right sides of each of the piezoelectric wires 140a and 140b to restrain and fix each of the piezoelectric wires 140a and 140b. , the upper thread 161 is formed in a form in which the left and right sides of the piezoelectric wires 140a and 140b are moved back and forth in a zigzag on the upper surface of the nonwoven fabric 140-1, and the lower thread 162 is on the lower surface of the nonwoven fabric 140-1. It is formed in the shape of an oblique line.

Here, although only the sensor wires 130a, ..., 130n provided in the first sensor unit 130 are illustrated in FIG. 5 as an example, the piezoelectric wires 140a and 140b of the second sensor unit 140 are also first Since the sensor wires 130a, ..., 130n of the sensor unit 130 are fixed in the same pattern, the piezoelectric wires 140a and 140b of the second sensor unit 140 are omitted in FIG. 5 .

As described above, the distance between the left and right both ends of the upper thread 161 crossing each of the piezoelectric wires 140a and 140b and the respective piezoelectric wires 140a and 140b is provided to maintain a distance of 5 mm or more, respectively, and the reason is that Since it is the same as the above-described first sensor unit 130 , a repeated description thereof will be omitted.

Therefore, the horizontal piezoelectric wire 140a and the vertical piezoelectric wire 140b are normally spaced apart, and a constant capacitance flows, and when a load is applied to the mat 100 and pressed, the horizontal piezoelectric wire 140a and the vertical piezoelectric wire Since a change in capacitance occurs as the distance of 140b approaches, a biosignal according to the body part of the sleeping person can be detected through the amount of change in the capacitance.

In addition, the horizontal piezoelectric wire 140a and the vertical piezoelectric wire 140b have curved bent portions 142 around the intersection 141 of the horizontal piezoelectric wire 140a and the vertical piezoelectric wire 140b, that is, in the intersection region, respectively. is formed

Each of the piezoelectric wires 140a and 140b has two bent portions 142 bent in opposite directions in the intersecting region, respectively, and a straight portion of each of the piezoelectric wires 140a and 140b connecting the two bent portions 142 . is provided with intersecting portions 141 intersecting each other, and the bent portions 142 of each of the piezoelectric wires 140a and 140b form an edge of the intersecting region.

As a result, the capacitance between the horizontal piezoelectric wire 140a and the vertical piezoelectric wire 140b formed as described above is increased, and the amount of change in capacitance between normal times and when a load is applied and pressed is also increased significantly, so that the second sensor unit ( 140) can improve the detection performance.

Accordingly, it is possible to sense and analyze the biosignal of the sleeping person through the amount of change in capacitance generated according to a change in the distance between the horizontal piezoelectric wire 140a and the vertical piezoelectric wire 140b as described above.

That is, when the sleeping person lies on the mat, the capacitance is different from each other at the intersection 141 of the horizontal piezoelectric wire 140a and the vertical piezoelectric wire 140b of the pressed part and the non-pressed part, and thus generated different According to the signal, it is possible to detect the sleeper's biosignal.
