Description

[0001] Portable toilet sensing devices [0002]

[0001] The present invention relates to a portable toilet-use sensing terminal, and more particularly to a portable toilet-use sensing terminal which senses a toilet in a non-contact manner to a human body and uses the low frequency RF to minimize the effect of errors caused by the human body, To a portable toilet-use sensing terminal.

In general, infants, elderly people with dementia, and those with severe mobility problems, such as those who are not aware of or can not handle bowel movements, are forced to handle urine with the help of their caregiver or caregiver. Therefore, the caregiver or the caregiver wears a diaper or undergarment to infants, a demented elderly or a serious patient, checks the defecation / urination from time to time, and treats the diaper or urine by a method of changing the diaper or undergarment.

At this time, it is inconvenient for the caregiver or caregiver to visually check the defecation and urination status of infants, demented elderly, and severe patients from time to time in order to check whether the urine is large or large, You are confronted with administrative difficulties that require frequent confirmation of multiple patients on a regular basis. In particular, when managing a large number of patients periodically, there arises a difficulty in directly confirming the condition of the diaper by changing one by one.

To solve this inconvenience, a technique has been proposed in which a urine sensor is attached to a diaper (or clothing) at all times, urine is detected using a urine detection sensor, and the urine is transmitted to the terminal. At this time, as a method of transmitting the urine detection signal to the terminal, an RF method is mainly used.

1A and 1B show an example of a conventional urine detection device using RF.

1A and 1B are diagrams illustrating a method of attaching a transmission antenna (or RF tag) 11 serving as a sensor to the diaper 10 on the basis of a macroscopic space (or environment) ) 12 radiates an RF signal to the transmission antenna 11 and determines the detection of the urine according to whether the RF signal returned from the transmission antenna 11 is received. At this time, the transmitting antenna (or the RF tag) 11 absorbs the radio wave (frequency) according to the urine (or the feces) and uses the signal amount (the signal becomes relatively small when the urine is generated) Signal (frequency). In this case, if interference is caused by the medium that affects the human body and surrounding frequency, it is difficult to detect urine and the probability of occurrence of error is very high.

Here, the conventional technique using RF as described above uses a high frequency to transmit the frequency to the macroscopic space well.

Meanwhile, FIG. 2 shows another example of a conventional urine detection device using RF. A urine detection sensor (or RF tag) 20 for detecting urine is mounted on a diaper 22 worn on the skin 21. The urine detection signal sensed by the urine detection sensor 20 is transmitted to the urine detection terminal 30. At this time, the urine detection signal generated by the urine detection sensor 20 is correctly transmitted to the urine detection terminal 30 on the space without the obstacle. However, when the diaper 30 is dressed on the diaper 30, The urine detection signal can not be transmitted to the urine detection sensor 30 accurately.

Fig. 3 is a configuration of another embodiment of the conventional urine detection device, which is a configuration separated from the sensor and the urine detection terminal. The sensor 41 for detecting the urine and the terminal 43 for detecting the urine are separated from each other. The terminal 43 is provided with a transmission / reception antenna 42 for receiving a signal wirelessly with the sensor 41. The urine sensor having such a configuration is inconvenient for use because the sensor 41 must be mounted on the object to be sensed.

On the other hand, another conventional technique for detecting urine in a noncontact manner is disclosed in Patent Document 1 and Patent Document 2 described below.

The prior art disclosed in Patent Document 1 provides a feces detector capable of discriminating whether there is a faeces or a urine as well as the presence / absence of the faeces and the number of the faeces by forming a plurality of capacitive electrodes on the flexible insulating thin film. The present invention also provides a capacitance type feces detector having a plurality of electrodes that can automatically detect the presence / absence of faeces and faeces and the distinction of faeces for people who can not make the urination process themselves.

Patent Document 2 discloses a detection unit comprising a capacitance sensor for sensing a change in capacitance caused by urine absorbed in a diaper in a noncontact manner; An output section that operates when there is a detection signal from the detection section; A power supply unit for supplying energy required for operation of the detection unit and the output unit; A detection unit / output unit / power supply unit electrically connected to each other, and a control unit for controlling the operation relationship of each part, thereby realizing a diaper detection device using a capacitance sensor. The thus-constructed toilet seat detection device automatically detects the infant and the melody, LED, or vibration by monitoring the inside of the diaper of the infant and the intensive care unit in a non-contact manner, The user will be notified of the use / nonuse of the contents through the output of wired / wireless.

Korean Registered Patent No. 10-1260997 (Registered on April 29, 2013) Korean Patent Publication No. 10-2009-0081886 (Published on July 29, 2009)

However, the above-described conventional techniques can detect the use of the capacitive method or the non-contact type, but it is inconvenient to attach the sensor for detecting the use of the non-contact type to the diaper.

In addition, since the conventional technique disclosed in Patent Document 1 uses a plurality of electrodes for sensing the small / small feces, there is a disadvantage in that a sensor construction cost is large. In addition, when the diaper is replaced due to detection of small / There is a disadvantage that resource waste is severe.

In addition, since the prior art uses a high frequency in order to transmit a frequency in a macroscopic space, there is a disadvantage in that an error occurs depending on the thickness of the clothes due to the influence of the human body in the microscopic space.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve all the problems occurring in the prior art as described above, and it is an object of the present invention to provide a method and apparatus for detecting the use of a human body by detecting low- So that it is possible to accurately determine the presence or absence of the use of the clothes regardless of the thickness of the clothes.

It is another object of the present invention to provide a portable type portable terminal which realizes convenience in use by implementing a portable type portable terminal with a sensor and a sensing terminal integrated therein.

Wherein the container detecting unit comprises: a transmitter mounted on a lower surface of a printed circuit board (PCB) on which a toilet-detecting component is mounted to transmit a low frequency; And a receiving unit mounted on a lower surface of the printed circuit board and receiving a low frequency transmitted from the transmitting unit as a to-be-detected signal when the to-be-transmitted is transmitted to the medium, wherein the to- And operates as a ground (GND).

The transmitter and the receiver are spaced apart from each other by a predetermined distance on the basis of the ground.

In this case, if the use-side detection unit does not detect the use of the toilet, the low-frequency transmitted from the transmission unit is weakly transmitted to the receiving unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A portable handy detecting terminal according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

4 is a block diagram of a portable type portable terminal 100 according to a preferred embodiment of the present invention.

The portable handy detecting terminal 100 according to the present invention includes a power supply unit 110, an oscillator 120, a usage detecting unit 130, an electromagnetic wave signal amplifying unit 140, a DC converting unit 150, a reference value setting unit 160 A usage detection unit 170, and a usage detection display unit 180.

The power supply unit 110 supplies power to the built-in battery 111.

The oscillator 120 oscillates with the power supplied through the power supply unit 110 and outputs an oscillation frequency (electromagnetic wave). To this end, it is preferable that the oscillator 120 generates a frequency range, that is, a low frequency that does not reach the human body.

The use detecting unit 130 is a sensor for detecting actual use, and radiates a low frequency generated by the oscillator 120 to a measurement object and senses the use of the use of the toilet as a medium.

As shown in FIG. 6, the receptacle sensing unit 130 includes a transmitter 131 mounted on a lower surface of a printed circuit board (PCB) 200 on which the toilet seat sensing component 300 is mounted, and transmitting a low frequency signal; And a receiving unit 132 mounted on a lower surface of the printed circuit board 200 and receiving a low frequency transmitted from the transmitting unit 131 as a toe detection signal when the toilets are transmitted to the medium. Here, the toilet-use detecting part 300 is mounted on the upper surface of the printed circuit board 200 and operates as a ground (GND), and means an electronic device such as an oscillator 120, an amplifier, a comparator, a display,

The transmitting unit 131 and the receiving unit 132 may be spaced apart from each other by a predetermined distance relative to the ground GND.

When the toilet is not detected, the use detection unit 130 detects that the low frequency transmitted from the transmitter 131 is weakly transmitted to the receiving unit 132 to the extent that it is impossible to detect the use of the toilet. For example. This eliminates the influence of the human body.

The electromagnetic wave signal amplifying unit 140 amplifies the electromagnetic wave signal output from the occupancy detecting unit 130.

The DC conversion unit 150 converts the used detection signal amplified by the electromagnetic wave signal amplification unit 140 into DC.

The occupancy detection determination unit 170 compares the DC converted by the DC conversion unit 150 with a set reference value and outputs the comparison result as a usage detection determination value.

The toilet-use detection display unit 180 visually expresses that the toilet-use detection value is output from the toilet-use detection / determination unit 170.

The operation of the portable toilet seat 100 according to the present invention will be described in detail with reference to FIGS. 4 to 6. FIG.

First, the power switch is turned on to detect the use of the portable object detecting terminal 100 according to the present invention. When the power switch is turned on, the internal battery in the power supply unit 110 is discharged, and the discharge voltage is supplied to each part of the terminal through the power switch to the driving power supply 3V. Here, the battery can be a rechargeable secondary battery or a primary battery that can be easily purchased on the market.

When the drive power is supplied, the oscillator 120 oscillates as a supply power source and generates an oscillation frequency (electromagnetic wave). It is preferable that the oscillation frequency generated at this time generates a low frequency in a frequency range that does not reach the human body. By using the low frequency which does not reach the human body, the occurrence of errors caused by the human body is minimized. That is, the low frequency RF technique is applied to a microscopic space close to a diaper, and is usefully used for detecting a toilet in a microscopic space. If a high frequency is used as in the conventional art, errors in detection of the use of the clothes occur depending on the thickness of the clothes due to human influence in the micro space. For example, when a very thin cloth such as a diaper is used, it is possible to detect a certain amount of use. However, when the inner garment is worn on the diaper, noises are introduced into the high frequency due to human influence. The present invention utilizes low frequencies in a microscopic space to overcome such shortcomings of the prior art.

The transmitter 131 of the container sensing unit 130 radiates the low frequency generated by the oscillator 120 as a measurement target. For example, assuming that the subject to be measured wears the diaper 402, wears the undergarment 403 again on the diaper 402, and wears a jacket (e.g., suit suit) 404 thereon as shown in Fig. 6 The portable urine sensing terminal 100 is simply brought into contact with the space suit 404 to perform the occupancy sensing operation.

Here, another feature of the present invention is that the use detecting unit 130, which is a sensor for detecting the use of a toilet, and the sensing terminal for detecting and identifying the user, are integrated into a single product. Accordingly, it is not necessary to separately attach a sensor for detecting a toilet to a measurement object, and a user simply touches the measurement part of the portable toilet-sensing terminal 100 lightly to the measurement object during use, And is performed in a single terminal through a series of processes.

The low frequency radiated from the transmitter 131 is detected through the receiver 132. At this time, the low frequency radiated from the transmitter 131 is transmitted to the receiver 132 using the medium as a medium. Unlike high frequencies, low frequencies are difficult to move to another space without a medium due to their characteristics. Accordingly, in the absence of the fluids, it is difficult for the low frequency radiated from the transmitter 131 to be transmitted to the receiver 132 (it can be very weakly transmitted) because there is no medium, and if the fluids are present, The low frequency radiated from the transmitter 131 is transmitted to the receiver 132 through the medium. Thus, the receiving unit 132 accurately detects the use of the toilet.

FIG. 5 is a configuration diagram of a bowl detecting part 130 which is the above-described bowl detecting sensor.

The transmitter 131 of the container detector 130 is mounted on the lower surface of the PCB 200 on which the container sensing component 300 is mounted and the receiver 132 is also mounted on the PCB 200). At this time, the toilet-use sensing part 300 is mounted on the upper surface of the printed circuit board 200 and operates as a ground (GND).

Here, the transmitting unit 131 and the receiving unit 132 may be spaced apart from each other by a predetermined distance from the ground GND.

Next, the electromagnetic wave signal amplifying unit 140 amplifies the electromagnetic wave signal (potted sensing signal) output from the above-described potty sensing unit 130 according to the set amplification degree and outputs the amplified signal. The thus-detected to-be-detected signal is transmitted to the DC conversion unit 150.

The direct current (DC) converter 150 converts the used detection signal amplified by the electromagnetic signal amplifier 140 into direct current. The DC voltage (the toilet seat detection signal) thus outputted is transmitted to the toilet use detection / discrimination unit 170.

The occupancy detection determination unit 170 compares the DC voltage converted by the DC conversion unit 150 with a reference value set through the reference value setting unit 160 and outputs the comparison result as a usage detection determination value.

For example, the occupancy detection determination unit 170 compares the reference value set by the reference value setting unit 160 with the occupancy detection signal (DC voltage) output from the DC conversion unit 150, Value.

Next, the use-state detection display unit 180 visually expresses that the use-case detection value is output from the use-case detection unit 170.

For example, the use detection display unit 180 visually displays presence / absence of use detection using the output signal of the usage detection / determination unit 170. In other words, only when the occupancy detection signal is generated, an output of the occupancy detection / determination unit 170 is generated and the light emitting diode (LED), which is a visual display device, is caused to emit light.

Accordingly, the user turns on the power source of the portable toilet seat sensing terminal 100, makes the detection part touch the object to be measured, and checks whether the light emitting diode (LED) is turned on or not.

Here, the present invention uses a light emitting diode that visually displays a power supply state, and when the power is supplied, the light emitting diode is lit to recognize that the user is currently operating the sensing terminal.

Thus, the user can easily recognize the power supply state or the operation state of the portable toilet seat sensing terminal 100.

In other words, the present invention applies a low-frequency RF technique to a microscopic space close to a diaper so that a low frequency generated in a transmitting unit is transmitted to a receiving unit using a toilet as a medium, so that the toilet can be accurately detected .

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
