1 is a diagram of a biological activity information management system 10 according to various embodiments of the present invention.

As shown, the bio-activity information management system 10 may include a pressure measurement device 100, a management server 200, and a user terminal 300. The bio-activity information management system 10 measures the pressure applied to the product worn by the user through the pressure measuring device 100, and generates the bio-activity information of the user according to the measured pressure.

The pressure measuring apparatus 100 measures the pressure value applied to the pressure measuring apparatus 100 by being included in or connected to a product worn by the user. Here, the product worn by the user may include, but is not limited to, clothes, accessories, etc., which may be worn on a specific part of the user's body or worn by the user. The pressure measuring device 100 may be configured with a fabric or the like so that the product is embedded in the product during the production process, or may be attached to the product after the product is produced.

The management server 200 is connected to the pressure measurement device 100 via a network, and generates the user's bio-activity information based on the information received from the pressure measurement device 100. The management server 200 is a device or a program that performs an intensive function to generate a user's bio-activity information, and is capable of communicating with the user terminal 300 through a network. Although not shown, the management server 200 may include a communication interface (e.g., a wired / wireless communication module), a memory, and a processor for performing functions.

The user terminal 300 is a computing device used by a user of a product or a guardian of a user, and can be moved or installed at a specific place by carrying the user. By way of example, and not limitation, the user terminal 300 may be, for example, a smart phone, tablet, PC, desktop, notebook or wearable device, but may be implemented in various forms of electronic devices that may be involved in the present invention.

FIG. 2 is a diagram of a pressure measurement device 100 according to various embodiments of the present invention, and FIGS. 3-4 illustrate a fabric sensor 110 according to various embodiments of the present invention.

The pressure measuring apparatus 100 may include a fabric sensor 110, a communication unit 120, a storage unit 130, a battery 140, and a control unit 150. [

First, the fabric sensor 110 is configured to measure the pressure applied to the pressure measuring device 100 or the fabric sensor 110 in a numerical value. The fabric sensor 115 has elasticity And the material 111 is coated.

According to various embodiments, fabric layer 115 may be implemented with conductors or conductors that are powered and current can flow continuously, periodically, or at any time. The conductors or conductors may be formed of the fabric layer 115 in combination with certain types of fabrics and may include, but are not limited to, conductive metals such as gold, silver, copper, nickel, and the like.

The stretchable material 111 includes a coating material such as silicone or polyurethane (PU) that can be stretched by external pressure as shown in FIG. 4, and can be coated to a predetermined thickness on the cloth layer 115. In Figure 3 or Figure 4, the stretchable material 111 is shown coated on either side of the fabric layer 115, but it is also possible to coat both sides.

When the fabric sensor 110 is formed or inserted into at least a part of the product and then moves while the user wears the product, changes the posture of the user, or sits or lays on an external object, The force is applied to the fabric sensor 110 in the vertical direction as shown in FIG.

The fabric sensor 110 may then sense a change in resistance due to a force applied to the fabric sensor 110 and a change in the stretch or expansion of the fabric sensor 110 (e.g., a change in length of the fabric sensor 110). This resistance change can be detected by further including a separate sensor that can sense a change in the current flowing through the fabric sensor 110 itself or the fabric sensor 110 can sense a change in resistance or current. The fabric sensor 110 may provide the sensed resistance change value to the controller 150. [

Although not shown, according to various embodiments, the fabric sensor 110 may include a stretchable material (e.g., a first coating layer) coated on one side with respect to the fabric layer 115 and a stretchable material (e.g., Second coating layer) may be coated with different thicknesses. Thereby, when the product including the fabric sensor 110 is worn by the user, the pressure measuring apparatus 100 or the management server 200 can distinguish the pressure applied from the user's body and the pressure externally applied.

Referring again to FIG. 2, the communication unit 120 may connect communication between the pressure measurement device 100, the management server 200, and the user terminal 300. For example, the communication unit 110 can communicate with the management server 200 or the user terminal 300 by being connected to the network through wireless communication or wired communication.

The storage unit 130 may temporarily or permanently store information generated or collected by the fabric sensor 110 or the control unit 150. The storage unit 130 may be implemented as a memory, a buffer, or the like.

The battery 140 performs a function of supplying power to the pressure measuring device 100. This battery 140 is implemented in a substantially small or compact structure and is electrically connected to the configurations of the pressure measuring apparatus 100. The battery 140 can be implemented in a form having a limited capacity or in a form that can be charged by a power supply.

The control unit 150 can check the changed resistance value based on the information collected through the fabric sensor 110 and transmit the resistance change value to the management server 200 through the communication unit 120. [

According to various embodiments, the communication unit 120, the storage unit 130, the battery 140, and the control unit 150 may be included in the fabric sensor 110. That is, the fabric sensor 110 may be embodied as one module including other configurations of the pressure measurement device 100 therein.

5 is a view of a fabric sensor 110 according to another embodiment of the present invention.

As shown, the fabric sensor 110 may be implemented as a fabric sensor 110b that includes a plurality of sub-fabric sensors (or fabric sensors) as well as a fabric sensor 110a that is formed as a single fabric. The plurality of sub-fabric sensors form an electrically parallel structure and are interconnected via a lead or lead (L).

If the length is long as in the fabric sensor of the 110a type, there is a possibility that the sensitivity lowering problem and the malfunction probability due to the noise become larger. Therefore, in order to improve this, a plurality of fabric sensors 110b having a length, a length, or a diameter of at least one of which is equal to or less than a predetermined value may be used. For example, the fabric sensor 110 can be broken up (for example, about 3 cm) and connected to several pieces by a thread or wire. That is, the sensors formed in a long direction in the lateral direction are shortly formed individually and are connected in parallel to reduce the resistance. However, this form is merely an example, and the form of the plurality of fabric sensors is not limited to the form of Fig.

6 is a flowchart of an operation for generating bio-activity information in the management server 200 according to various embodiments of the present invention. Hereinafter, contents of generating user-customized bio-activity information based on the pressure value will be described with reference to FIG.

The management server 200 according to various embodiments of the present invention may receive the sensed pressure value periodically or at any time in real time in the pressure measuring device 100 (S610). In this case, the management server 200 may receive the identification information of the fabric sensor 110 or the pressure measurement device 100. [ In order to ascertain which product the pressure measuring device 100 or the fabric sensor 110 is included in and which position it is in the product.

Specifically, the pressure measuring device 100 or the fabric sensor 110 may be given a unique identification number and stored in a memory or the like, and the management server 200 may store the product information corresponding to the unique identification number, Information on the position where the fabric sensor 110 is inserted can be DB-managed. Thereby, the management server 200 can check which area of the fabric sensor 110 or the pressure measuring device 100 is applied to which area (S630).

Next, the management server 200 may generate the user's bio-activity information based on the confirmed product and the sensed pressure value (S650). The bio-activity information is generated based on the pressure value generated by the user's physical activity or external factors. In the embodiment of the present invention, since the pressure measuring device 100 senses the pressure applied locally to the fabric sensor 110, it is possible to determine the product to be worn by the user and the fabric sensor 110 may be located in different places.

According to some embodiments, the erection diagnostic value may be generated based on cumulative information of the pressure value received from the pressure measuring device 100 when the type and position of the identified product are in the vicinity of the genitalia of the male undergarment . Such an erection diagnostic value may be an example of biological activity information.

To this end, the management server 200 numerically measures the time information from which the pressure value exceeding the preset magnitude value is successively measured and the number of times the pressure value exceeding the preset magnitude value are measured from the pressure measuring device 100 .

Specifically, the management server 200 estimates time information in which a pressure value exceeding the predetermined size value is continuously measured as a first numerical value on a second basis, A value obtained by multiplying the number of one section by 10 can be calculated as a second numerical value.

For example, if the pressure value corresponding to the predetermined size value is 3.0 and the pressure value exceeding 3.0 is continuously measured for 20 seconds, the management server 200 calculates the first numerical value as 20 can do.

This first numerical value is updated by being added by a plurality of intervals. For example, if a pressure value exceeding 3.0 over the course of a day (which may vary depending on the setting) is present for more than 10 consecutive measured intervals, another first numerical value of 10 may be calculated. In this case, the first numeric value, which is the sum of the first numeric values and is finally updated, is calculated to be 30. Here, the continuously measured value can be interpreted as a state in which a pressure value exceeding a preset value is continuously received for a minimum time (for example, 2 seconds) that can be changed according to the setting.

On the other hand, since there are a total of two consecutive intervals in which input values exceeding 3.0 are continuously measured during the day, the management server 200 can calculate 20 as the second numerical value by multiplying the number of times 2 by 10.

Also, the management server 200 can check the magnitude of the maximum pressure value among the pressure values measured in the two intervals, and can check the weight corresponding to the maximum pressure value in the interval information stored in the DB. For example, the weight of the pressure value in the management server 200 may be set to be 1.5 times as large as 3.0 to 4.0 times, and twice as much as 4.0 to 5.0 times. If the maximum pressure value in the two consecutive intervals is 4.5, the management server 200 can confirm twice the weight value.

Finally, the management server 200 may generate a value obtained by multiplying the weight value by a value obtained by adding the first numerical value and the second numerical value to the user's erection diagnostic value. According to the above example, the erection diagnosis value is (30 + 20) * 2, so that it can be calculated as 100. [ Such an erection diagnosis value can be exemplarily assumed to have a superior erection ability as the numerical value is higher. The physician or the hospital can effectively and continuously calculate the bio-activity information according to the erection ability of the user by applying the pressure measuring device 100 of the present invention to the clothes worn by the patient.

According to another embodiment, the pressure measuring device 100 may be included in a baby band or a baby band that an infant wears on a boat. The management server 200 determines whether the product is a baby belt or a baby band based on the identification information of the fabric sensor 110 or the pressure measuring device 100 and whether the fabric sensor 110 is located on a belt or a belt .

The management server 200 may generate the bio-activity information of the user based on the period during which the pressure value is measured and the magnitude of the pressure value. Specifically, the management server 200 may generate at least one of respiration information, attitude information, or risk of the infant as the bio-activity information by quantifying the period of the pressure value and the magnitude of the pressure value.

In the case of infants, respiratory weakness may be caused by various causes, or it can be seriously injured by an external impact. Accordingly, when the pressure measurement device 100 is applied to a child product, the management server 200 can generate respiration information of the infant as bio-activity information based on the period and size of the pressure value. In addition, the management server 200 can determine whether the infant is lying down or leaning based on information that the fixed pressure value is continuously received or the pressure value of the specific pattern is continuously measured.

According to some embodiments, when a pressure value satisfying a preset value is received, the management server 200 calculates a pressure value of the pressure value received after the pressure value exceeding the predetermined value is received, The risk can be estimated by adding a weight to the size. As a result, the guardian of the infant receives more information not only of the breathing information and the attitude information of the infant, but also of the information that there is a possibility of danger.

In the case of infants, the instantaneous pressure value may be below a certain lower value or exceed a certain higher value when breathing becomes weak or an external shock is applied. According to various embodiments, a fabric sensor 110 including a first coating layer and a second coating layer coated with different thicknesses may be used to more clearly distinguish such an external impact or a user's living body change. For example, in the case of an infant, since the pressure value applied to the fabric sensor 110 according to respiration is generally low, a surface of the infant body on the basis of the fabric layer 115 is provided with a stretchable material 111) can be applied. That is, the fabric sensor 110 may include a second coating layer (the user's body side) of less thickness than the first coating layer (the outwardly facing surface).

The management server 200 can transmit an emergency signal (e.g., a phone call or a push message) to the user terminal of the infant, which is stored in advance, when the pressure value received subsequently becomes an abnormal value, have. If the predefined normal range pressure value is received after the starting point, the management server 200 can continuously receive the pressure value and generate the bio-activity information such as breathing information or attitude information.

In the above description, the form of the band is limited to the infant, but the various embodiments of the present invention are not limited thereto. The pressure measuring device 100 or the fabric sensor 110 according to various embodiments of the present invention can be used for pressure sensing by being installed in a desired application product, For example, it can be used as a bed system for preventing a pressure ulcer to be worn on a user's body, or as a measure of motion of an elderly living alone (recognized as occurrence of an abnormal symptom after movement on the floor of an elderly elderly living alone).

The management server 200 may convert the bio-activity information generated as described above or information obtained by visually processing the information into a database or transmit the database to the user terminal 300.

According to the above-described embodiments, the pressure applied to the product worn by the user can be continuously and effectively measured, and the user can receive customized bio-activity information according to the user and the product.

The steps of a method or algorithm described in connection with the embodiments of the present invention may be embodied directly in hardware, in software modules executed in hardware, or in a combination of both.
