Hereinafter, the smart diaper system according to the present invention will be described in detail with reference to the attached drawings.

As shown in FIGS. 1 to 9, the smart diaper system 1 proposed by the present invention includes a smart diaper 2 three-dimensionally provided with a pattern sensor capable of detecting urination and defecation; A repeater (3) that calculates and transmits the presence of defecation and urination, the direction of discharge according to posture, and the absorption area based on the data transmitted from the smart diaper (2); a management unit (7) that stores data transmitted from the repeater (3), transmits a diaper (2) change alarm, and displays real-time information on a monitor; a server (5) that analyzes data transmitted from the repeater (3) and defines individual urination and defecation patterns; It includes a mobile device (M) capable of transmitting and receiving data by being connected to the server 5 and the management unit 7 through a network.

This smart diaper (2) is three-dimensionally arranged and includes pattern sensors (20, 21, 22, 23) that can detect defecation or urination, and sensors (15) that can detect temperature, humidity, hydrogen, gas, and current. By providing a , the change in current and temperature and humidity can be measured and analyzed by artificial intelligence mounted on the repeater 3, thereby improving the detection accuracy of urination and defecation.

To explain in more detail,

The smart diaper 2 includes a diaper body 17; pattern sensors (20, 21, 22, 23) that are three-dimensionally disposed on the diaper body (17) and change the amount of current during urination and defecation; It is equipped with a sensor (15) that detects temperature, humidity, hydrogen, and gas, and a gyro sensor (16) that detects posture, and includes a sensor (15), a gyro sensor (16), and a pattern sensor (20, 21, 22, 23). It includes a terminal (4) that receives defecation and urination signals from ), calculates them, and transmits and receives the results to the repeater (3).

In the smart diaper 2 having this structure,

The pattern sensors 20, 21, 22, and 23 are arranged three-dimensionally, with a pair on the left and right and a pair on the top and bottom.

That is, the pattern sensors 20, 21, 22, 23 are arranged in a flat shape on the surface of the diaper body 17, and the first and second sensors 20, 21 are arranged at a certain distance from each other, and the diaper body ( It is arranged in a flat shape on the bottom of 17) and includes third and fourth sensors 22 and 23 arranged at a certain distance from each other.

These first to fourth sensors 20, 21, 22, and 23 have the same shape and have a structure in which conductive patterns are arranged in a zigzag shape.

At this time, the conductive pattern can be implemented in various ways, for example, by placing a conductive wire on the surface of the diaper body 17 or by printing conductive carbon ink on the surface of the diaper body 17. .

In addition, the first and second sensors (20, 21) are composed of a pair of conductive wires (24, 26), and the ends (32, 34, 36, 38) are connected to the terminal (4) to apply current or Changes can be detected.

Therefore, when defecating or urinating while wearing the smart diaper (2), stool and urine come into contact with the pattern sensors (20, 21, 22, and 23), and since stool and urine are electrolytes, the first and second patterns (20, 21) are used. The amount of current flowing changes.

And the amount of current is transmitted to the terminal 4 so that the amount of change can be measured by the current amount detection sensor.

At this time, since a plurality of first and second sensors 20 and 21 are disposed, the diaper can be divided into a plurality of zones in the X-axis direction, so that defecation and urination points can be more clearly specified.

In addition, the third and fourth sensors (22, 23) are also composed of a pair of conductive wires (28, 30), and the ends (40, 42, 44, 46) are connected to the first and second sensors (20, 21). By connecting to the terminal 4 in the same way as , current can be applied or the amount of change can be detected.

That is, when defecating or urinating while wearing the smart diaper (2), the defecation or urination that enters the diaper body (17) and reaches the bottom comes into contact with the third and fourth sensors (22, 23), and the urine and feces are Since it is an electrolyte, the amount of current flowing through the third and fourth patterns 22 and 23 varies.

And the amount of change can be calculated by transmitting the amount of current to the terminal 4.

At this time, a plurality of third and fourth sensors 22 and 23 are arranged so that the diaper can be divided into multiple zones in the Y-axis direction, allowing defecation and urination points to be more clearly specified.

In the above, the first to fourth sensors (20, 21, 22, and 23) are divided into four zones, but the present invention is not limited to this and can be divided into arbitrary zones depending on the product design environment.

In addition, a sensor having the same shape as the first and second sensors (20, 21) is installed between the first and second sensors (20, 21) and the third and fourth sensors (22, 23). The sensors 20 and 21 can be placed at a 90-degree angle, and their ends can be connected to the terminal 4.

In this case, urination or defecation can be detected by detecting multiple zones in the diaper in the Z-axis direction.

As a result, by compartmentalizing the diaper in the X, Y, and Z axes, urination or defecation can be detected three-dimensionally.

Although it is described as a conductive wire above, it can be any type that allows current to be applied and the amount of change to be detected.

Meanwhile, the terminal 4 receives current values from a plurality of ends (32, 34, 36, 38, 40, 42, 44, 46) of the first to fourth sensors (20, 21, 22, 23). module 50; a calculation module 52 that compares a plurality of input current values with normal values and calculates the amount of change; A determination module 54 that determines whether the calculated change amount is the change amount of the sensors 20 and 21 arranged in the horizontal direction or the change amount of the sensors 22 and 23 arranged in the depth direction and transmits the change to the repeater, and a power supply. Includes supply department (not shown).

In these terminals,

The reason for dividing the diaper into multiple zones by arranging the first and second sensors (20, 21, 22, 23) left, right, up and down is to accurately determine the amount of defecation or urination on the surface of the diaper and the amount of defecation or defecation that has seeped into the inside of the diaper. It is for this purpose.

In addition, there are differences in the direction of dispersion and diffusion of urine depending on the gender and posture of the diaper wearer, and also, since the absorbent area of the diaper 2 is different for each amount of urine when the absorbent material is wet and when it is not wet, the amount of urine is reflected by reflecting this. In order to accurately calculate , it is sensed by dividing it into multiple zones: top, bottom, left, and right.

In this way, the change value of the current calculated by the terminal 4 and the identification data of the detected sensor are converted into digital values and then transmitted to the repeater 3 for analysis.

In addition, since urination has a difference in the amount of current in the diffusion area depending on the posture of the wearer, it is necessary to apply this.

That is, in the present invention, the wearer's posture is divided into eight types as follows.

In the table above, the square model represents the wearer, and the arrow represents the direction in which urine is sprayed.

That is, 180 degrees means that the wearer is lying face down on the floor while wearing a diaper (2), 0 degrees means that the wearer is lying down facing the ceiling, and 90 degrees means that the wearer is lying on his side. do. At this time, the lying angle can be detected by the gyro sensor 16.

As such, the direction of urine discharge is different depending on the posture, and the detection area and absorption area of the pattern sensors (20, 21, 22, 23) are different accordingly.

As a result of measuring the amount of current for each posture, it was measured as follows.

posture One 2 3 4 5 6 7 8 Current amount (mA) 10.3 12 12.7 12 15 12.7 12 11.7

In the above measured values, the absorption unit area was set to 0.1 cm2 and the maximum current measurement value was set to 15 mA. The amount of current flowing between the two electrodes of the electronic recognition pattern sensor (20, 21, 22, 23) is proportional to the absorption area. As a result of the measurement, the maximum current measurement value was measured to be 15 mA when the posture was 180 degrees.

In addition, the pattern sensors (20, 21, 22, 23) of the diaper (2) increase the amount of current in proportion to the area where urine contacts the pattern, so the amount of urine is detected by storing the measured change in real-time current and calculating the integrated value. do.

In addition, in the present invention, the difference in the detection area of the pattern according to gender and the difference in the absorption area for each urination amount as time is delayed were created into a database as shown in Table 3 below and a correction value was applied.

The size of the database is 60 urination volume (in units of 10 cc) x 2 gender x 8 posture x 6 delay time x 5 absorption rounds = 28,800 cells.

In addition, in each cell, the average value of the current measurement value of 100 tests of salt water with a similar salinity as urine is stored, and the current value measured in real time is compared with the database to extract the amount of urination. In addition, the difference in absorption area according to the amount of urination when the absorbent material of the diaper (2) is not wet and when it is wet was also applied as a correction factor.

The experiment was conducted on the amount of urination in units of 10 cc, and it was assumed that the diaper (2) was changed every 5 urinations.

In addition, since the diaper 2 is maintained in a sealed state and the urine absorbent is made of a porous material that does not allow absorbed urine to be discharged, the area wetted by the absorbent is always constant depending on the amount of urine and the diffusion rate is also constant.

Meanwhile, in the present invention, that is, the pattern sensors 20, 21, 22, and 23 are arranged in a flat shape on the surface of the diaper body 17, and the first and second sensors 20, 21 and the diaper body 17. By consisting of the third and fourth sensors 22 and 23 disposed on the bottom of the diaper, defecation or urination can be effectively detected in the space between the diaper surface and the bottom.

That is, when the pattern sensor is disposed only on the diaper body 17, only defecation or urination on the surface of the diaper can be detected, and it is difficult to detect defecation or urination that has penetrated the inside of the diaper. In the present invention, the first and second sensors (20,21) can be placed on the surface of the diaper to detect defecation or urination on the surface, and the third and fourth sensors (22,23) can be placed on the bottom of the diaper to detect defecation or urination that has soaked into the diaper. there is.

And, the amount of change can be calculated by comparing the amount of current sensed by the calculation module 52 and the reference current amount.

In addition, the determination module 54 determines whether the sensor detecting the change in current is the first and second sensors (20, 21) on the surface of the diaper or the third and fourth sensors (22, 23) on the bottom of the diaper. do.

Meanwhile, in the summer or in patients with high fever, the basal body temperature is high, so deviations due to sweat may occur, so deviations are minimized by applying correction values based on the temperature and humidity within the measured diaper (2). This correction value correction can be calculated by the calculation module 25 of the repeater 3.

In addition, as described above, the differences in the direction of urine discharge, detection area, and absorption area according to posture, the difference in detection area in the pattern according to gender, the difference in absorption area according to the amount of urination as time is delayed, and the application of correction values according to the absorbent are It can be calculated by the calculation module 25 of the repeater 3, which will be described later.

Meanwhile, the sensor 15 provided in the diaper detects various types of ingredients and transmits them to the terminal 4. For example, by detecting temperature, humidity, gas, ammonia, and hydrogen, it detects stool, farts, menstruation, bad odor, etc. Detect the smell of air freshener.

Then, the measured value is transmitted to the terminal 4 and converted into a digital value.

A temperature sensor is a method of detecting temperature using the property of an element changing its electrical characteristics depending on temperature. These temperature sensors can be of various types, such as thermocouples, temperature measuring resistors, thermistors (NTC), metal thermometers, thermistors (NTC, PTC, CTR, PIR, TIR) and thermosensitive ferrite types.

There are various types of humidity sensors, including a method that uses changes in electrical resistance or capacitance caused by absorption into porous ceramics or polymer membranes, and a method that uses changes in the resonant frequency of the oscillator due to changes in the weight of the absorbent material installed on the oscillator. can be used

A gas sensor is a sensor that measures ammonia concentration and consists of an ammonium ion selective membrane or an ammonia gas permeable membrane and a complex hydrogen ion electrode. Ammonia concentration can be measured by measuring the change in hydrogen ion concentration caused by ammonium ions or ammonia gas diffusing through the membrane with a hydrogen ion electrode.

Additionally, the gyro sensor (16) can detect the body position by measuring the angular velocity.

The results measured by the sensor 15 are converted into digital values in the terminal 4 and then transmitted to the repeater 3 for analysis.

That is, after receiving the measured values from the sensor 15, the repeater 3 uses artificial intelligence to determine whether there is defecation or urination, whether there is a foul odor, the direction of ejection depending on the posture, the absorption area, etc., and also determines the measured values as necessary. Perform correction.

For example, if the measured temperature, humidity, and ammonia concentration are outside the normal range compared to the preset table values, it is determined that the condition is defecation, urination, or odor.

In more detail, the repeater 3 includes a receiving module 23 that receives sensor measurement values from the terminal 4; an arithmetic module 25 that analyzes the received measurement values using artificial intelligence to three-dimensionally determine whether there is defecation, urination, or bad odor; a graphics module 28 that displays a graph based on calculated results; It includes an output module 27 that transmits the calculated results to the server 5 and the management unit 7.

In this repeater (3),

The receiving module 23 receives measured values transmitted from the terminal 4, temperature sensor, humidity sensor, ammonia sensor, current sensor, and gas sensor, and receives angle data about the wearer's posture from the gyro sensor.

Then, the calculation module 25 analyzes each data received from the terminal 4 and calculates the area of urination or defecation detected by the first and second sensors 20 and 21 on the surface of the diaper and the area of the bottom of the diaper. By comparing the areas of urination or defecation detected by the third and fourth sensors 22 and 23 and calculating them, and applying them separately according to the wearer's posture, the amount of urination or defecation that has penetrated into the diaper can be determined.

For example, if the current value changes only in the first and second sensors 20 and 21, and the current value does not change in the third and fourth sensors 22 and 23, urination or defecation remains only on the surface of the diaper. It can be judged that

On the other hand, if the current values of the first and second sensors (20, 21) and the third and fourth sensors (22, 23) all change, it can be determined that urination or defecation has invaded not only the surface but also the inside of the diaper. You can.

This computational process is carried out by programs such as deep learning programs. Deep learning is a machine built based on an artificial neural network (ANN) to enable computers to learn on their own like humans using various data. It is a learning method.

Using artificial neural networks, it is possible to classify and cluster data related to defecation and urination, such as temperature, humidity, gas, posture, and current amount, by placing several layers on the data you want to classify or cluster. Judgment can be made.

In other words, an artificial neural network consists of an input layer, multiple nodes, and an output layer. This artificial neural network extracts shape features of temperature, humidity, gas, posture angle, current amount, and urine discharge direction data and uses the features as input values for other machine learning algorithms to classify or cluster by shape to determine whether urination or defecation is present. can be judged three-dimensionally.

This artificial neural network includes a deep neural network, and a deep neural network refers to a neural network composed of multiple layers among neural network algorithms.

In other words, the artificial neural network is composed of multiple layers, and each layer consists of several nodes, and at each node, an operation to classify the shape actually occurs, and this computational process mimics the process that occurs in the neurons that make up the human neural network. It is designed to

A node responds when it receives stimulation above a certain size, and the size of the response is roughly proportional to the product of the input value and the node's coefficient (or weights).

Generally, a node receives multiple inputs and has coefficients equal to the number of inputs. Therefore, by adjusting this coefficient, different weights can be assigned to various inputs.

Finally, all multiplied values are added and the sum is input to the activation function. The result of the activation function corresponds to the output of the node, and this output is ultimately used for classification or regression analysis.

Each layer consists of several nodes, and the activation/deactivation of each node is determined depending on the input value. At this time, the input data becomes the input of the first layer, and after that, the output of each layer becomes the input of the next layer again.

All coefficients continue to change slightly during the shape learning process of the data, and as a result, they reflect which input each node considers important. And training of a neural network is the process of updating these coefficients.

Through this process, the calculation module 25 of the repeater 3 calculates temperature, humidity, gas, posture angle, current amount, and urine discharge angle data to three-dimensionally determine whether defecation or urination is performed in the space between the surface and bottom of the diaper. You can.

That is, the calculation module 25 can more clearly specify the defecation and urination point in the ), the point of defecation and urination in the Y-axis direction can be more clearly specified by the amount of current change, and by applying posture data to these data, the amount of urine or defecation can be calculated three-dimensionally.

In this way, the amount of defecation or urination in the diaper can be accurately determined three-dimensionally, making it possible to change the diaper in a timely manner and prevent unnecessary changes.

In addition, the calculation module 25 stores the measured values of the temperature and gas within the diaper 2 for a certain period of time. For example, 60 measured values are stored in the data table at 10-second intervals.

Then, the arithmetic mean and moving average of the stored values are obtained, and then a graph is created as shown in FIG. 8 using the graphic module 28.

In other words, if Δx, which is the difference between the instantaneous measurement value and the arithmetic mean value, exceeds 20% of the arithmetic mean value, a change has occurred within the diaper (2), so the measurement cycle is adjusted to 1 second intervals, the measurement data is stored, and the arithmetic mean value and moving average value are stored. After obtaining , create a real-time graph.

In addition, the change factors are identified by comparing the standard distribution characteristic curves of feces, farts, menstruation, odors, and air fresheners obtained through experiments with real-time graphs.

Therefore, by specifying these change factors, it is possible to more accurately determine whether defecation and urination have actually occurred.

In addition, by storing the real-time graph immediately before changing the diaper of the wearer of the smart diaper (2) in the database, the characteristic curve for each error factor can be corrected to minimize individual deviation.

Additionally, because defecation is accompanied by urination due to the nature of defecation, if urination is not detected even after defecation is specified, the data is rechecked for 30 seconds to specify defecation.

When defecation is specified, a notification signal is immediately output through the output module 27, and an alarm is output when the amount of urination reaches the individual set value.

In addition, the receiving module 23, the operation module 25, the graphics module 28, and the output module 27 are devices that decode and execute instructions, like a CPU (Central Processing Unit), and are a control device and operation module. It consists of devices and registers.

On the other hand, if the calculation module 25 determines that the amount of urination or defecation is small, that is, a diaper change is not necessary, the operation module 25 will dry the corresponding part by applying a predetermined current to the conductive wire connected to the area where the defecation or defecation is. It may be possible.

At this time, the heating wire may be placed separately from the conductive wire.

Meanwhile, the server 5 analyzes data transmitted from the repeater 3 and the management unit 7, defines individual urination and defecation patterns, and transmits them to nurses and guardians.

This server 5 refers to a typical server, which is computer hardware on which a server program is running. It monitors and controls the entire network, such as printer control or file management, or connects to other networks through a mainframe or public network. Sharing software resources such as data, programs, and files, or modems, fax machines, and printers. Supports sharing of hardware resources such as other equipment.

In the above, it has been explained that the repeater (3) performs the function of analyzing data by artificial intelligence to determine whether there is defecation or urination, whether there is an odor, and correcting the measured value, and then transmitting the data. However, the present invention is not limited to this and is performed by the server (5). ) can also perform this function.

The management unit (7) stores the measurement values received from the repeater (3), sends a diaper (2) replacement alarm to the caregiver via mobile according to the judgment information, and displays real-time information on the monitor so that the nurse can recognize it. , All data is transmitted to the server (5).

Meanwhile, Figure 8 shows a graph for this defecation recognition algorithm.

As shown, this graph shows a standard recognition curve, a converted body temperature curve, and a defecation characteristic curve, and whether or not a defecation occurs is recognized based on these curves.

First, the calculation module 25 determines whether urination is detected for a certain period of time after defecation is detected.

In other words, if urination is detected within about 30 seconds, it detects a defecation state and compares the trajectory of the standard recognition curve and the defecation characteristic curve.

If the measurement value is within the defecation range, it is notified to the outside world that defecation has actually occurred.

Additionally, nurses and guardians can use these notifications to determine whether urination is occurring in real time and take necessary actions.

Meanwhile, in the above description, the pattern sensors 20, 21, 22, and 23 are three-dimensionally arranged up, down, left, and right. However, the present invention is not limited to this, and as shown in FIG. 9, the pattern sensor 20 may be disposed only on the surface of the diaper body 17.

In addition, in the present invention, the terminal 4 calculates the amount of change in current by the calculation module 52, and the sensor that detects the change in current by the judgment module 54 is connected to the first and second sensors 20 on the surface of the diaper. , 21), or the third and fourth sensors 22, 23 on the bottom of the diaper, but the present invention is not limited to this and the operation module of the repeater 3 can also perform this function. there is.
