Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a means for detecting a fallen object and detecting the state thereof. When the fallen object is excrement of a human being or an animal, the physical condition detection means based on the state and the cleaning control of the discharge part It relates to means.
[0002]
[Prior art]
Hereinafter, a conventional falling object detection device will be described. As disclosed in Japanese Patent Application Laid-Open No. 62-69085, the conventional falling object detection device has a difference in collision force depending on the type of grain when the grain falling from the diffusion device collides with the grain type sensor. It is detected as a difference in values, and the detection result is input to the control unit via the A / D converter and the input interface as grain information, and compared with the reference information stored in advance in the ROM, so that it is a grain. The type of wheat grain is determined, and wheat or straw is displayed on the display LED, for example, for adjusting the drying speed.
[0003]
On the other hand, there are human and animal excrement as fallen objects, and the hospital is looking at the health condition from this excrement, but in recent years, devices for home use have also been proposed, connecting homes and medical institutions to treat and monitor. Proposal of a system for performing, for example, Japanese Patent Laid-Open No. 5-228116, is provided with various measuring devices in residential equipment, collects biological information passively with personal use, and stores it in the controller. Discloses a means to input biometric information to other residential equipment for health management and to make it work, and to contribute personal health information to health management and maintenance. We are measuring and trying to make use of it for the health management of the human body.
[0004]
In addition, there is a warm water cleaning toilet seat as a treatment device for living bodies after discharging excrement as fallen objects, but the cleaning method is to wash a wide area of the anal anus by shaking the cleaning nozzle up and down and left and right There is something like that.
[0005]
[Problems to be solved by the invention]
In such a conventional falling object detection device, the means disclosed in Japanese Patent Application Laid-Open No. Sho 62-69085 detects the type of grain using the difference in collision force due to the difference in grain size as the difference in electrical resistance value. However, because it is a means to detect when the falling grain directly hits the grain type sensor, there is a problem with the durability of the sensor, and it falls continuously like liquid Is difficult to distinguish from the difference in the collision, for example, it is difficult to detect the difference in the particle size of the liquid. In addition, since excrement that has various differences in size, weight, shape, continuity, etc. depending on the physical condition of humans and animals contains moisture, the state of the excrement should be identified by the change in electrical resistance value. It was difficult. In other words, this is a method for detecting hitting a sensor, and is a means for identifying different types, not a means for identifying different states of the same type.
[0006]
On the other hand, the means disclosed in Japanese Patent Application Laid-Open No. 5-228116 is a health management means that senses the state of a living body and informs the person or medical staff of the information, and measures the living body in the toilet facility. It is a necessary system for people undergoing medical treatment and managers who need a certain disease. It was an exaggeration for people who were healthy and wanted to know their health, and there were many inconveniences in terms of actual usability. Although urine analysis has been carried out, no stool analysis has been proposed for grasping the health status of the digestive system.
[0007]
Furthermore, the hot water flush toilet device is being developed for cleaning functions such as improving the flexibility of the cleaning range and improving the cleaning power, but the cleaning range and the cleaning time can be determined according to the state of the excrement. There was nothing to do.
[0008]
The present invention solves the above-mentioned problem, and detects that a fallen object such as a human body or an object, such as excrement, collides with, enters, or enters an object by a sensor installed at a position different from the object. Another object of the present invention is to provide a fallen object detection device that can detect the state of a fallen object that can be used for estimation of the physical condition of a human being or an animal, and that can be used for cleaning control of a portion that releases the fallen object.

[0025]
Embodiments of the present invention will be described below.
[0026]
(Embodiment 1)
Hereinafter, a first embodiment of a falling object detection device of the present invention will be described with reference to the drawings. The present embodiment relates to the present invention described in claims 1, 2, 4, and 5. FIG. 1 is a block diagram showing the configuration of the present embodiment. In the figure, reference numeral 1 denotes a collision phenomenon measuring means for measuring a phenomenon when a falling object 2 collides, enters or enters a falling object 3, and 4 denotes a falling object 2 according to data measured by the collision phenomenon measuring means 1. It is a fallen object estimation means for estimating the state. The collision phenomenon measuring unit 1 includes a light emitting unit 5, a light receiving unit 6 that receives a signal from the light emitting unit 5, and a storage unit 7 that stores a signal output from the light receiving unit 6 as measurement data. The fallen object estimation means 4 compares the measurement data stored in the storage unit 7 of the collision phenomenon measurement means 1 when there is no collision with the measurement data when there is a collision, and generates difference data between the two. The reference data storage unit 9 storing the reference data for identifying the difference data output by the comparison unit 8 and estimating the state thereof, and the comparison unit 8. An estimation unit 10 is provided for estimating the state of the falling object 2 by comparing the signal at the time of collision with the data in the reference data storage unit 9. The data may be an analog signal or a digital signal.
[0027]
FIG. 2 is a schematic diagram illustrating the configuration of the object 3 to which the vehicle is dropped, the light emitting unit 5 and the light receiving unit 6, and their surroundings. In the present embodiment, the object 3 is described as water. As shown in the figure, the fallen object 2 collides, enters, or mixes in a substantially vertical direction with respect to the water surface 11 of the object 3 that is water, and the light emitting unit 5 irradiates the collided, entered, or mixed portion obliquely. The light receiving unit 6 is set so as to receive light from an oblique direction with respect to the water surface 11 where the falling object collides, enters, or enters.
[0028]
The operation of the above configuration will be described. The collision phenomenon measuring means 1 measures a phenomenon when the falling object 2 collides, enters or enters (hereinafter simply referred to as a collision) with the water 3 (object) at the falling destination, and the falling object estimation means 4 detects the collision phenomenon. The state of the fallen object is estimated according to the data measured by the measuring means 1. That is, in the collision phenomenon measuring means 1, the light emitting unit 5 irradiates the water surface 11 where the falling object collides, and the light receiving unit 6 receives light from the water surface and temporarily stores the signal output. Therefore, when there is no collision, the storage unit 7 stores the output signal of the light receiving unit 6 when there is no collision as a background signal. Next, when a falling object collides, the light receiving unit 6 receives light from the water surface 11 and stores the signal in the storage unit 7. The comparison unit 8 compares the signal at the time of collision stored in the storage unit 7 with the background signal when there is no collision, and generates a difference signal. The reason why the comparison unit 8 generates the difference signal is that the incident light received by the light receiving unit 6 when there is no collision is subtracted to extract only the phenomenon caused by the collision. The estimation unit 10 estimates the state of the fallen object 2 by referring to the data of the standard data storage unit 9 for the difference signal. In addition, the state said here means the form and property which arise variously according to a situation even if it is the same kind.
[0029]
Hereinafter, the measurement of the collision phenomenon will be described with reference to FIG. 2, taking as an example the case where the collision target object 3 is water. Now, it is assumed that the light emitting unit 5 emits red laser light, and the linear linear laser light is irradiated from the lens 12. This laser light enters the line AA ′ on the water surface, is refracted and reaches the bottom surface of the water, and forms a red line BB ′. On the other hand, the light receiving unit 6 includes a slit 13 so as to have a linear linear sensitivity having a certain width, and a light receiving element so as to measure the brightness of the line AA ′ on the water surface. The light receiving unit 6 is located on the opposite side of the light emitting unit 5 with respect to the vertical plane in the line AA ′, and is installed so as to receive light from the line AA ′. At this time, when the water surface is flat, the light on the water bottom surface is partially received as the light of the line CC ′.
[0030]
When there is no fallen object 2, the water surface 11 is quiet and flat, so that the projected laser light passes through the water surface 11 with almost no reflection and reaches the line BB ′ on the water bottom surface. Therefore, the light receiving unit 6 monitoring the water surface with the line AA ′ only receives the background signal. This signal is a signal when there is no collision on the water surface 11 and is stored in the storage unit 7 as a signal when there is no collision. Next, when the fallen object 2 falls and collides with the water surface 11, a large wave is generated on the water surface 11. Therefore, the projected laser beam is scattered or irregularly reflected by the line AA ′ on the water surface 11 so that the red laser beam can be partially seen by the light receiving unit 6. The light receiving unit 6 receives the red light and outputs various output signals that vary spatially (in this case, luminance distribution on the line) and temporally. This signal is a signal in which the background signal and the signal due to scattering or irregular reflection are superimposed. Therefore, the comparison unit 8 compares and calculates the difference between the signal of the light receiving unit 6 when the falling object 2 falls and the signal of the light receiving unit 6 stored in the storage unit 7 in advance when there is no collision. Only the signal is extracted, and the state of the fallen object 2 is estimated by the fallen object estimation means 4 in comparison with the state stored in the reference data storage unit 9 in advance. Of course, the comparison unit 8 always receives the signal from the light receiving unit 6 and compares it with the background signal. When the difference signal is zero or close to zero, it is obvious that there is no drop. Further, the background signal may be a signal of the light receiving unit 6 stored immediately before the collision, or may be a signal in which a predetermined signal is fixed and stored in advance.
[0031]
Hereinafter, a method for estimating the state of the fallen object 2 will be considered with respect to human excrement. Now, the following three are assumed as representative states of feces as excrement.
[0032]
State 1: Hard stool that is excreted during constipation State 2: Normal stool (relatively hard stool)
Condition 3: Complete diarrhea
When defecation is performed in any of the states 1 to 3, an output signal is output in a certain range in terms of space and time.
[0033]
FIGS. 3 to 5 are waveform diagrams showing the signal of the comparison unit 8 at one point on the line AA ′ as digital data when the stool enters the line AA ′. That is, it is a waveform obtained by digitizing a signal obtained by subtracting the signal of the light receiving unit 8 stored in the storage unit 7 of the collision phenomenon measuring means 1 when there is no collision from the signal of the light receiving unit 8 when the stool collides with the water surface. . Needless to say, the signal when there is no collision in this case is slight reflected light from the water surface or reflected light from the bottom of the water. Further, the figure shows a waveform inverted with respect to the amount of light received by the light receiving unit 6.
[0034]
FIG. 3 is a waveform diagram showing, as digital data, the signal of the comparison unit 8 for one point on the line AA ′ when the stool enters the line AA ′ in the state 1. In the figure, the first stool passage period XX ′ is a signal portion generated when the stool passes through the light receiving section route. The period YY ′ is a signal portion generated by the wave after entering. In the case of the rolling stool in the state 1, the waveform on the water surface is a wave generated by the entry of a small stool, so a small wave is continuously generated instead of a large wave. Further, the period ZZ ′ indicates a state in which the wave has become smaller and the horizontal plane has finally become quieter.
[0035]
FIG. 4 is a waveform diagram showing, as digital data, the signal of the comparison unit 8 for one point on the line AA ′ when the stool enters the line AA ′ in the state 2. In the case of the state 2, since the period of the stool passage period XX ′ is long and the stool itself is large, a large wave is formed in the period YY ′ after the entry. Further, the period ZZ ′ indicates a state in which the wave becomes smaller and the horizontal plane becomes quieter.
[0036]
FIG. 5 is a waveform diagram showing, as digital data, the signal of the comparison unit 8 for one point on the line AA ′ when the stool enters the line AA ′ in the state 3. In the case of the state 3, since the stool is divided into soft stools and discharged, the stool passage period XX ′ becomes discrete. In the period YY ′ after the rush, an irregular waveform appears due to the flights that rushed into one after another. And eventually, it shifts to the period ZZ ′ in which the waves subside, but because the specific gravity of the stool itself is light here, it floats on the water surface (containing gas in the stool), and the reflected light on the water surface continues to receive the light. 6 is incident.
[0037]
The state of the stool can be estimated from these waveform data. For example, considering the measurement of the first flight passage period XX 'and the measurement of the period ZZ', three types of states can be identified by combinations of the periods XX ', YY', ZZ 'time, YY' period, etc. The conditions such as the time, the period, and the combination thereof may be stored in advance in the reference data storage unit 9 in the falling object estimation means 4. In addition, as the conditions become more detailed, more fecal conditions can be identified. Further, if the output of the comparison unit is viewed as an analog signal instead of a digital signal, more types of identification can be made.
[0038]
As described above, the shape of the water surface at the time of entry fluctuates depending on the type of stool, the fluctuation is measured as a signal due to fluctuations in the incident light of the light receiving unit 6, and the data of the signal is analyzed with reference data to analyze the stool The state can be determined. Actually, there are more types of stool than in the above-mentioned form, and the amount of stool needs to be identified for several excretion actions, not just one discharge. For these, it is possible to identify many types of stool by collecting reference data by many experiments and storing them in the reference data storage unit 9.
[0039]
Although the method for detecting fecal properties has been described above, it can also be applied to urine tests. That is, in the case of urine, it can be detected as a difference in water surface behavior due to differences in physical quantities such as volume, viscosity, and specific gravity. For example, by observing the difference between the case where bubbles remain for a long time after urination and the case where the generation of bubbles is small, the change in the properties of urine can be identified.
[0040]
In this embodiment, an example of detecting a change in the amount of received light due to waves as a water surface state detection unit has been described, but it is also possible to estimate the state of a falling object by recognizing an image of the water surface wave state. . It is also possible to observe how the floating floated on the water surface vibrates, associate the floating state with the movement of the water surface, and finally estimate the state of the falling object. Moreover, in the case of the water surface in a water tank, the pressure fluctuation of a small pressure sensor attached to the water tank can be measured to estimate a wave, and the state of a falling object can be estimated.
[0041]
The object may be anything, such as water in a container, water in a toilet bowl, toilet bowl itself, or a sink that receives water, and may be liquid, solid, or gas.
[0042]
Further, the collision phenomenon measuring means 1 can detect from the transient phenomenon at the time of contact to the equilibrium phenomenon with respect to the collision, intrusion or mixing between the falling object and the object. It may be limited to phenomenon data. In addition, sound, light, odor, temperature change, concentration change, physical shape change, etc. generated between the falling object and the object at the time of contact can be used as effective data. These may be generated in the fallen object or may be generated in combination in both.
[0043]
Further, the data stored in the reference data storage unit 9 of the falling object estimation means 4 may be described in a language, not limited to numerical data. Further, the estimation may be made from a reasoning such as fuzzy reasoning.
[0044]
(Embodiment 2)
Hereinafter, a second embodiment of the falling object detection device of the present invention will be described with reference to the drawings. This embodiment relates to the present invention described in claims 1, 3, 4, and 5. FIG. 6 is a block diagram showing the configuration of the present embodiment. In addition, the same number is attached | subjected to the same component as 1st Embodiment, and description is abbreviate | omitted. The present embodiment is different from the first embodiment in that the light emitting unit 5 is set to irradiate an area of the underwater 20 into which the falling object 2 enters.
[0045]
The operation of the above configuration will be described. The light emitting unit 5 emits water 20, the light receiving unit 6 receives the irradiated signal through the water 20, and the storage unit 7 temporarily stores the signal output of the light receiving unit 6 as measurement data. Next, the comparison unit 8 compares the measurement data at the time of entry stored in the storage unit 7 with the measurement data at the time of no entry, and generates difference data. The estimation unit 10 uses the difference data as a reference. By analyzing with reference to the standard data in the data storage unit 9, the contents and amount of the falling object 2 are estimated from the absorption of light depending on the contents of the falling object 2.
[0046]
For example, when it is desired to detect occult blood in urine, the collision phenomenon measuring means 1 stores in the storage unit 7 measurement data when there is no rush from the output signal of the light receiving unit 6 and measurement data when there is a rush. . The fallen object estimation means 4 generates difference data from the measurement data when there is no entry and the measurement data when there is entry by the comparison unit 8, and the estimation unit 10 stores the difference data in the reference data storage unit 9. Compared with the stored data without occult blood, it can be estimated that there is occult blood if it is equal to or greater than a threshold value. In addition, feces, urine or occult blood in urine, protein, sugar (urine sugar), fecal occult blood in stool, etc., blood in water, medicine, cosmetics, etc. can be applied regardless of liquid, solid or gas.
[0047]
Further, when it is desired to measure the amount of stool in the wash water, the estimation unit 10 may compare with the data without stool. This amount of stool can be used for automatic cleaning of the toilet, and the cleaning can be completed when the amount of stool in the water can be estimated to be zero. In this case, the collision phenomenon detection means 1 can collect both the excessive entry data and the mixed data after reaching the equilibrium state.
[0048]
(Embodiment 3)
Hereinafter, a third embodiment of the falling object detection device of the present invention will be described with reference to the drawings. This embodiment relates to the present invention described in claims 6 and 7. FIG. 7 is a block diagram showing the configuration of the present embodiment. In addition, the same number is attached | subjected to the same component as 1st Embodiment, and description is abbreviate | omitted. The present embodiment is different from the first embodiment in that a physical condition estimation unit 14 is added and the physical condition is estimated from the state of excrement estimated by the fallen object estimation unit 4. The physical condition estimation unit 14 includes a reference value storage unit 15 that stores data serving as various physical condition references in advance, and a physical condition estimation unit that estimates the physical condition by comparing the data of the falling object estimation unit 4 with the reference data. 16.
[0049]
The operation of the above configuration will be described. Note that the description of the operations common to the first embodiment is omitted. In this embodiment, the fallen object is a stool. The stool state is detected by the estimation unit 10 as a combination of state 1, state 2, or state 3. The physical condition estimating means 14 estimates the physical condition with the physical condition estimating unit 16 referring to the data of the stool state with the reference data of the reference value storage unit 15. For example, when only the state 1 is used as the reference data: physical condition = constipation.
In state 2 only: physical condition = normal.
In state 3 only: physical condition = diarrhea.
Repeat of state 1: physical condition = constipation (constipation decreases with the number of times).
Repeat of state 2: physical condition = normal.
Repeat of state 3: physical condition = severe diarrhea.
Change from state 1 to state 2: physical condition is becoming normal.
Change from state 2 to state 3: physical condition = diarrhea.
Change from state 3 to state 1: physical condition = diarrhea will soon stop.
Change from state 1 to state 3: physical condition = diarrhea.
Change from state 3 to state 2: physical condition is becoming normal.
Change from state 2 to state 1: physical condition = normal.
Can be stored and registered in the reference value storage unit 15 in advance, and the physical condition can be inferred by comparing with the data estimated by the estimation unit 10.
[0050]
(Embodiment 4)
Hereinafter, a fourth embodiment of the falling object detection device of the present invention will be described with reference to the drawings. The present embodiment relates to the present invention described in claim 8. FIG. 8 is a block diagram showing the configuration of the present embodiment. In addition, the same number is attached | subjected to the same component as 1st Embodiment, and description is abbreviate | omitted. This embodiment is different from the first embodiment in that it includes a cleaning control means 18 for controlling the cleaning method of the discharge part 17 that discharges the fallen object 2, and excrement estimated by the fallen object estimation means 4. According to the state, the cleaning device 19 that cleans the discharge part 17 that has released the excrement is controlled.
The operation of the above configuration will be described. In the case of the normal stool in the state 2, the cleaning device 19 is controlled so that the discharge portion 17 is uniformly washed with the cleaning water in the discharge portion 17 in a normal amount normal time manner. In the case of diarrheal stool in state 3, since the discharge part 17 is contaminated with stool, the cleaning device 19 is controlled so that the cleaning water is uniformly cleaned by the wide range cleaning method including the periphery of the discharge part 17.
[0051]
As described above, the cleaning range and time can be automatically set in accordance with the stool properties, the cleaning method can be changed, and the cleaning can be performed efficiently and reliably with less cleaning water. In addition, automatic cleaning can be automatically stopped.
[0052]
As is apparent from the above description of the embodiment, the fallen object detection device of the present invention can obtain the following effects.
[0053]
The falling object detection apparatus of the present invention measures a phenomenon when a falling object collides, enters or enters a falling object by the collision phenomenon measuring means, and the state of the falling object from the measured data by the falling object estimation means. Thus, even if the fallen object looks the same, the difference in state can be identified.
[0054]
Further, the falling object detection device of the present invention measures the collision, intrusion or mixing phenomenon of the falling object due to the fluctuation of the liquid level or the liquid in the liquid drop by the collision phenomenon measuring means. The fluctuation of the liquid that is easily affected by falling objects during entry, mixing well reflects the properties of the falling objects, and is suitable for detecting falling objects such as humans and animals. The analysis is relatively simple and the wave fluctuation persistence replaces the short-falling phenomenon with the long-term phenomenon and provides a lot of information. Moreover, excessive fluctuations in the liquid can detect the contents in the fallen object, such as occult blood, and can also detect the amount of stool in the water, which can be reflected in the automatic cleaning control of the toilet.
[0055]
Further, the falling object detection device of the present invention irradiates a region of an object where a falling object collides, enters, or enters by a light emitting unit, receives light from the region by a light receiving unit and converts it into a signal, Is stored in the storage unit as measurement data, so that the falling phenomenon can be measured in a non-contact manner with respect to the falling object and the object to be dropped, and the sensor for measurement is not damaged. Moreover, the measurement data before the fall and the measurement data at the time of the fall can be stored and held, and can be used to obtain a change in the measurement data before and after the collision.
[0056]
In the falling object detection device of the present invention, the comparison unit compares the measurement data before and after the collision to obtain the difference data, extracts only the data by the collision, and the estimation unit extracts the difference data as the reference data of the storage unit. Thus, the state of the falling object is estimated, so that the state of the falling object can be identified based on a predetermined standard.
[0057]
In addition, the present invention can estimate the physical condition related to the digestive system and the urinary system by estimating the physical condition from the estimated state of the fallen object, and does not require any special preparation or operation. The physical condition can be determined from daily excretion.
[0058]
In addition, according to the present invention, the physical condition is estimated based on a criterion stored in advance in the reference value storage unit, so that the physical condition can be estimated based on a predetermined criterion, and the physical condition is met. You can estimate your physical condition.
[0059]
In addition, the present invention provides a cleaning device that controls the cleaning unit that cleans the discharge part that has released the fallen object according to the state of the fallen object by the cleaning control means, so that the cleaning is performed according to the toilet characteristics. By automatically setting the range and time to be performed, it is possible to efficiently wash with less washing water, and to wash reliably. Furthermore, automatic stop can be performed by automatic cleaning.
