Diaper management system using multiple radios {A MANAGEMENT SYSTEM OF A DIAPER USING MULTIPLE WIRELESS METHOD}

The present invention is a diaper using a multi-radio system that can be processed collectively by managing a large number of people by receiving the presence / absence of excretion of the demented elderly, critically ill, infant or newborn wirelessly via the terminal to display the change situation A management system, more specifically, by detecting moisture in the air using a non-contact capacitive sensor that is not in direct contact with urine, significantly reducing the risk of corrosion and failure, and also counting the number of urine counts. The present invention relates to a diaper management system using a multi-wireless method that prevents the consumption of diapers and interoperates with a computer to store and manage the number of urine in a database.

In general, stool demented elderly, critically ill, infants or newborns wear disposable panties or straight paper diapers or diapers.

In case of wearing such disposable diaper or diaper, diaper cover should be added on top of it for hermeticity and waterproofness. Especially, diaper cover must be replaced quickly and washed for reuse. As a result, most parents or guardians prefer disposable paper diapers that are superior in sealing and absorbency and are easy to wear.

However, this paper diaper can be used for a long time due to excessive belief, especially when infants have stool or urine several times, and the outer surface of the diaper is made of tarpaulin. Unless it is checked frequently, it is not easy to visually and visually identify the toilet so that it is time to replace it in a timely manner.

As a result, enzymes secreted from the large digestive tract and ammonia in urine can irritate the skin of weak infants and cause skin diseases such as diaper rash, thereby harming the wearer's health.

In an attempt to solve this problem, a detachable attachment to the inner surface of the diaper or attaching it to the diaper is possible so as to inform the parents or guardians of the infants or the sick in recent years when the diaper is changed accurately and conveniently. It is equipped with a sensor to detect toilets.

Hereinafter, a diaper management system using a multiple wireless method according to the present invention will be described in detail with the accompanying drawings.

1 is a configuration diagram of a diaper management system using a multiple wireless method according to a first embodiment of the present invention, FIG. 2 is a block diagram of FIG. 1, and FIG. 3 is a conceptual diagram illustrating a stage of the capacitive sensor of FIG. 2. .

As shown in Figures 1 to 3, by receiving the presence / absence of excretion of the demented elderly, critically ill, infant or newborn wirelessly through the terminal to display the change situation by one person to manage a large number, to process them collectively The present invention relates to a diaper management system using multiple radio systems.

This multi-wire diaper management system consists of two parts, each sensing unit 210 mounted on the worn diaper so that at least two or more people can be managed simultaneously, and unique to each sensing unit 210. It is composed of a single terminal 100 that can be assigned to the code number individually to confirm the presence or absence of excretion.

The terminal 100 includes the first and second storage units 110 and 111, the resonant element 112, the identification unit 120, the control unit 130, the first communication unit 140, and the display unit 150. It is composed.

) Function.

The first storage unit 110 has a structure in which a unique code number is stored to assign a code number to each sensing unit 210.

The second storage unit 111 stores the detection resonance frequency detected by each sensing unit 210 in real time or for a set time unit, and a terminal dedicated operating system (OS) may be installed. It is a structure that stores the wearer's registration information (name, height, age, sex, physical characteristics, patient's disease name).

The first storage unit 110 and the second storage unit 111 are composed of two memories, but may be configured by storing a code number and an OS in one memory.

The identification unit 120 assigns a unique code number through the first storage unit 110 and selects a detection resonance frequency to which the corresponding code number is assigned so that the change of the state of the diaper 200 can be known.

The controller 130 performs a function of comparing the detection resonance frequency of each sensing unit 210 with the reference resonance frequency of the resonance element 112 to determine whether or not the diaper 200 is excreted.

The first communication unit 140 transmits the reference resonant frequency of the resonance element 112 and the code number of the first storage unit 110 to each of the sensing units 210, and the code detected by each of the sensing units 210. It receives the detection resonance frequency by number.

A ZigBee module may be applied to the first communication unit 140 and the second communication unit 211 described later. ZigBee modules are the most suitable wireless communication means for sensor networks, consuming low power and greatly simplifying node expansion. In addition, it may be configured as an infrared communication module or a Bluetooth communication module.

The display unit 150 performs a function of comparing the reference resonance frequency of the resonance element 112 and the detection resonance frequency of each sensing unit 210 by the control unit 130 to display the presence / absence of excretion.

In addition, the initialization button 160 and the operation button 170 is formed on the surface of the terminal 100 is configured.

Here, the initialization button 160 functions to initialize the detection resonance frequency stored for each time unit set in real time or in the second storage unit 111.

In addition, the operation button 170 serves to receive the detection resonance frequency of the sensing unit 210 at the start or initialization of the terminal 100 again.

In addition, the terminal 100 has a built-in speaker 180 to recognize the presence / absence of excretion in advance, and then configured to enable the presence / absence of the diaper visually through the display unit 150.

In addition, each sensing unit 210 is mounted on the diaper 200 worn on a number of demented elderly, intensive care, infants or newborns, respectively, and functions to detect excretion of the diaper 200.

The sensing unit 210 includes a second communication unit 211, a filter unit 212, a capacitive sensor 213, and a signal converter 214.

First, the capacitive sensor 213 detects moisture evaporation of the diaper 200 in a non-contact manner, and detects the amount of moisture based on a reference resonance frequency received from the resonance element 112.

The capacitive sensor 213 forms a circuit 213b having a spiral shape with equal intervals on the surface of the stage 213a composed of non-conductors, and a reference resonance frequency is input to the input terminal 213c of the circuit 213b. The detection resonance frequency is output to the output terminal 213d to sense moisture by the phase difference between the reference resonance frequency and the detection resonance frequency.

The function of the capacitive sensor 213 will be described briefly as follows.

As shown in Fig. 3, the circuit formed on the surface of the stage 213a made of the non-conductor is composed of a concentric spiral structure having the same spacing.

Here, the spacing between the circuit copper wires formed in a spiral shape is the same, and an input end 213c is formed at one end of the circuit, and an output end 213d is formed at the other end of the circuit.

In this structure, when moisture is sensed between the copper wires of adjacent circuits 213b, the capacitance increases, so that the resonance frequency increases from the input terminal 213c to the output terminal 213d.

Accordingly, the phase difference between the detection resonance frequency and the reference resonance frequency output to the output terminal 213d is gradually increased.

Since the phase difference corresponds to the time difference between the detection resonance frequency and the reference resonance frequency, it is possible to measure the amount of moisture currently sensed through the time difference.

Therefore, when the time difference due to the phase difference between the reference resonance frequency and the detection resonance frequency in the absence of moisture is grasped, the time difference caused by the phase difference between the reference resonance frequency and the currently measured detection resonance frequency is measured to detect the amount of water present. You can do it.

In addition, the capacitive sensor 213 is a structure that detects the capacitance by the amount of moisture detected on the surface of the stage 213a, so that a small amount of moisture does not have the disadvantage of detecting the capacitance. Even though a small amount of moisture is sensed, the resonance resonance frequency having a large phase can be obtained by passing through a spiral circuit 213b and affecting each other between adjacent circuits, thereby enabling more accurate moisture measurement.

The second communication unit 211 receives a code number and transmits a detection resonance frequency to which the code number is assigned to the terminal 100.

The filter unit 212 functions to remove noise of a code number or to filter a corresponding code number.

The signal converter 214 converts the detection resonance frequency detected by the capacitive sensor 213 into a digital signal and transmits the digital signal to the terminal 100 through the second communication unit 211.

In addition, the sensing unit 210 may further include an olfactory sensor 215 interlocked with the signal converter 214.

When the feces are feces, the smell sensor 215 checks this as an odor so as to inform the terminal 100 whether to replace the diaper 200 through the signal converter 214 and the second communication unit 211.

Hereinafter, the operation of the diaper management system using the multi-radio system according to the present invention will be described with reference to the block diagram of FIG. 3.

The present invention can be managed by increasing the number of appropriate management personnel for one person, but will be described by way of example, 10 persons that can be properly managed by one person.

A plurality of sensing units 210 are mounted on each of the ten diapers 200 worn.

At this time, the sensing unit 210 may be embedded in the diaper, or may be formed on the diaper 200 by forming a separate locking means. In addition, the sensing unit 210 is to be transmitted / received through the second communication unit 211, it is obvious that a small battery (not shown) is built.

In addition, the power of the terminal 100 is turned on to oscillate various unique code numbers CODE1 to CODE10 of the first storage unit 110 and the reference resonance frequency of the resonance element 112.

Then, the sensing unit 210 mounted on each diaper 200 removes the noise through the filter unit 212 and selects and receives the corresponding unique code number.

For example, when one of the sensing units 210 receives a signal assigned code 1 through the filter unit 212, the capacitive sensor 213 sets the detected resonance frequency based on the signal. In this case, code 1 is assigned to the detection resonant frequency, and thus, the terminal 100 recognizes that the sensing unit 210 that oscillates the coded detection resonant frequency 1 is number 1.

Meanwhile, the capacitive sensor 213 of the code 1 sensing unit 210 detects the amount of water in the air evaporated into the atmosphere through the diaper using the stage 213a to generate a detection resonance frequency.

The amount of water changed in real time is converted to the oscillation frequency so as to be transmitted to the terminal 100 through the signal converter 214 and transmitted to the terminal 100 through the second communication unit 211.

The terminal 100 receives the detection resonance frequency to which code 1 is assigned through the first communication unit 140.

The received detection resonance frequency first selects the sensing unit 210 to which code 1 is assigned through the identification unit 120 of the terminal 100. As a result, only the first sensing unit 210 is displayed on the display unit 150.

On the other hand, the detection resonance frequency selected by the identification unit 120, the control unit 130 to determine whether the urine and the amount of urine compared with the resonance frequency of the resonant element.

The detected resonant frequency is continuously accumulated in the second storage unit 111 to count the number of urine times of the sensing unit 210 to which code number 1 is assigned.

In addition, it is determined whether the diaper 200 is replaced according to the amount of urine or the number of urine. When the amount of urine is small or the number of urine is small, the corresponding sensing unit 210 to which the code number 1 is assigned to the second storage 111 is given. The number of urine detections and the amount of urine are displayed on the display unit 150 in real time.

In this case, when urine is detected unconditionally regardless of the amount of urine and the number of urine, the urine is confirmed by the administrator by vibrating by an alarm generated by the speaker 180 and a vibrating element (not shown). Recognize

In addition, in the case of infants, the amount of urine is very small, so that the alarm can be generated at the number of times three or four times by the computer 300 setting described later.

Meanwhile, when the diaper 200 equipped with the first sensing unit 210 displayed on the display unit 150 is replaced, pressing the reset button 160 of the display unit 150 detects the first sensing unit 210. Initialize the amount of information, and press the operation button 170 to be restarted.

At this time, if the information amount of the code number 1 sensing unit 210 is initialized by pressing the initialization button 160, the second storage unit 111 can back up the existing information and then connect the computer 300 to graph it. have.

In addition, the sensing unit 210 is provided with an olfactory sensor 215, it is configured to know whether the bowel movement in the feces in addition to urine.

That is, when the smell is confirmed through the olfactory sensor 215 in the diaper 200 equipped with the sensing unit 210 of the code number 1, it is converted into the oscillation frequency through the signal converter 214 and received by the terminal 100. Received by the control unit 130 to determine the bowel movement, it is immediately displayed through the display unit 150 can be replaced by the administrator immediately diaper (200).

At this time, as a notification means, it is possible to set such that the alarm and the other alarm of the urine described above can be distinguished from when the urine is detected.

As shown in FIG. 4, the second embodiment includes the first embodiment, and the terminal 100 has a structure in which a USB port 190 is further provided to be interlocked with the SW of the computer 300.

Through this, the excretion information of the diaper 200 stored in the terminal 100 may be transmitted to the SW 310 of the computer 300 to be converted into a DB and displayed as a graph and a table through a display connected to the computer 300.

Accordingly, in the case of a serious patient in the hospital, the number of feces is important, the doctor checks the change in urine and feces in the graph or table through the corresponding SW 310 of the computer 300, to accurately check the health of the patient The risk of dust can be greatly reduced, so it can be used as a medical aid.

In addition, the user's registration information (name, height, age, sex, physical characteristics, patient's disease name) stored in the OS of the terminal 100 can be edited through the keyboard of the computer 300, and the corresponding sensing unit The diaper excretion of 210 may be configured to accurately know through the terminal.
