At this time, the convex portion 11D provided on the facing surface 11A of the toilet bowl 11 is spaced from the outer peripheral edge of the perforated plate 13 at its lower end.

FIG. 4 shows the appearance of the perforated plate according to the embodiment. The perforated plate 13 includes a perforated plate main body 20 and a detection device 30 mounted so as to be fitted inside the perforated plate main body 20.例文帳に追加The detection device 30 detects liquid present in the toilet bowl 11 above the outlet 11C, and transmits information related to the detection result to an external estimation device. The information to be transmitted may be the detected result itself or information generated from the detected result. Based on the information received from the detection device 30, the estimation device estimates the state of discharge at the discharge port 11C or the discharge path (discharge path 10K, drain pipe D, etc.).

The detection device 30 may be configured integrally with the perforated plate main body 20 or may be configured separately from the perforated plate main body 20 . In the former case, the technique of the present embodiment can be applied only by replacing the perforated plate of the existing urinal with the perforated plate 13 of the present embodiment without replacing or repairing the urinal itself. Therefore, the introduction cost can be reduced. In the latter case, the detection device 30 may have a shape that can be fitted into or placed on the existing perforated plate main body 20 . As a result, the technique of the present embodiment can be applied only by fitting or placing the detection device 30 of the present embodiment on the perforated plate of the existing urinal without replacing or repairing the urinal itself. Therefore, the introduction cost can be reduced.

FIG. 5 schematically shows the configuration of the perforated plate according to the embodiment. The perforated plate body 20 has a bowl-like shape with a recess 21 inside, and the detection device 30 has an outer shape that fits into the recessed portion 21 of the perforated plate body 20 . The detection device 30 includes a main body 31, a substrate 51 on which a communication device functioning as a transmission section is mounted, and a pair of electrodes 54 functioning as a detection section.

The main body 31 has a cover 40 , a housing portion 50 and a bottom surface 60 . The housing portion 50 houses a substrate 51 , electrodes 54 , and a battery (not shown) that supplies power to the substrate 51 . The substrate 51 comprises a processing device 52 and a communication device 53 . Processing device 52 includes an ammeter that measures the current flowing between a pair of electrodes 54 . The processing device 52 generates communication data to be sent to the estimating device based on the measurement results of the ammeter. The processing device 52 may, for example, directly use the current value or resistance value measured by the ammeter as communication data, or count the time during which the current value measured by the ammeter is continuously equal to or greater than a predetermined value. It may be communication data. The communication device 53 transmits the communication data generated by the processing device 52 to the estimation device by wireless communication.

The electrode 54 is provided so as to protrude to the outside of the housing portion 50 . If there is drainage between the electrodes 54, the current will be detected by the ammeter since the drainage will provide continuity between the electrodes 54. FIG. While the urinal 1 is being used, or while flushing water is being discharged after the urinal 1 is in use or when not in use, the current is detected by the ammeter because the drainage flows inside the perforated plate 13. . When the discharge port 11C and the discharge path are in a normal state, the liquid level of the waste water becomes lower than the electrode 54 after a certain period of time has passed, so that the electrodes 54 are no longer electrically connected and the current is no longer detected by the ammeter. However, if the drainage port 11C or the drainage path is clogged and the drainage is not discharged normally, the time for which the drainage is accumulated inside the perforated plate 13 becomes longer, so the current is detected by the ammeter. become longer. Therefore, in this embodiment, based on the time during which the current is continuously The state of wastewater discharge from the discharge port 11C, such as overflow of wastewater from the bowl 11, is estimated. As a result, it is possible to accurately estimate the discharge state with a simple configuration, so that the introduction cost can be reduced.

Since urine contains more ions than the clean water used for the wash water, the resistance measured by the ammeter is higher when urine is flowing between the electrodes 54 than when only wash water is flowing. value becomes smaller. Therefore, by analyzing the current value or resistance value measured by the ammeter, it is possible to estimate the frequency, amount, time, components, etc. of urination. Even if the wastewater is discharged normally, the current is continuously detected by the ammeter during the period of urination and the period of cleansing water being discharged. Since it varies from person to person, the period during which the current is continuously sensed by the ammeter also varies from person to person. Therefore, the period of urination may be identified based on the current value or resistance value measured by the ammeter. As a result, the influence of individual differences in urination time can be reduced, and the state of waste water discharge can be estimated more accurately. If water containing detergent or the like is used as cleaning water instead of clean water, the current value or resistance value of the cleaning water may be measured in advance.

The cover 40 has a tubular portion 41 , an upper surface 42 and a water collecting portion 45 . The housing portion 50 is housed in a watertight space formed by the tubular portion 41 , the top surface 42 and the bottom surface 60 . An opening 43 is provided in the tubular portion 41 between the upper surface 42 and the water collecting portion 45 above the position of the electrode 54 . The upper surface 42 is slanted downward toward the opening 43 . An opening 44 is also provided between the upper surface 42 and the water collecting portion 45 on the opposite side of the opening 43 . The water collecting portion 45 is formed in a donut shape so as to be smoothly connected to the edge portion 22 of the perforated plate body 20 . The upper surface of the water collecting portion 45 is inclined so that the upper portion of the opening 43 is lower. Drainage flows from the edge portion 22 of the perforated plate body 20 to the water collecting portion 45 and falls from the central opening of the water collecting portion 45 to the upper surface 42 . When a large amount of waste water remains, the waste water is discharged from both the openings 43 and 44. When the amount of waste water becomes small, the remaining waste water flows downward toward the opening 43 due to the inclination of the upper surface 42, and is opened. 43 to discharge between the electrodes 54 . Thereby, it is possible to more reliably detect that the waste water remains in the toilet bowl 11. - 特許庁

FIG. 6 shows the condition when the waste water is accumulated in the toilet bowl. If the communication device 53 is submerged in the drainage water, the radio waves transmitted from the communication device 53 may be attenuated, which may hinder communication. Therefore, at least the communication device 53 is configured to float on water. In this embodiment, the substrate 51 on which the communication device 53 is mounted is housed in the housing portion 50, and the housing portion 50 is housed in the main body 31, so that the detection device 30 as a whole is configured to float on water. In another example, only the communication device 53 or only the communication device 53 and a part of the structure may float in water, and the rest of the structure may sink together with the perforated plate body 20 . With such a configuration, it is possible to secure the communication strength of the communication device 53 and improve the stability of wireless communication. In addition, since the power required for communication can be reduced, the battery can be used for a long time.

A floating height detection unit may be further provided for detecting the floating height when the configuration including the communication device 53 floats on the waste water accumulated in the toilet bowl 11 . The flying height detection unit may include, for example, a vertically extending resistance wire and an ammeter that measures the resistance value of the resistance wire. In this case, the lower end of the resistance wire is attached to the perforated plate body 20 or a structure that maintains a state of being submerged together with the perforated plate body 20 without floating on water, and for a structure that floats on drainage, depending on the floating height An electrical contact is provided that is configured to vary the location of electrical connection with the resistance wire. The floating position detection unit may be an ultrasonic sensor, a distance sensor, or the like for detecting the height between the floating structure and the perforated plate main body 20 or the like. Based on the floating height detected by the floating height detection unit, the water level of the waste water accumulated in the toilet bowl 11 can be estimated, so the discharge state of the waste water can be estimated more accurately. In addition, it is possible to detect the overflow of the waste water from the toilet bowl 11 and issue a warning before the waste water overflows from the toilet bowl 11. - 特許庁

FIG. 7 shows another example of the perforated plate according to the embodiment. In the example shown in this figure, the detection device is built into the perforated plate 13 . 7(a) is a top view of the perforated plate 13, and FIG. 7(b) is a side view of the perforated plate 13. FIG. A circular recess 71 is formed near the center of the upper surface of the perforated plate 13 , and an electrode 72 is provided on the bottom near the center of the recess 71 . A peripheral edge portion 70 of the upper surface of the perforated plate 13 is inclined so as to become lower toward the end, and an opening 73 is provided on the inclined surface. The lower part of the perforated plate 13 has a shape that fits into the discharge port 11</b>C, and an electrode 54 is provided on the lower side surface of the opening 73 .

Since the electrode 72 is provided on the upper surface of the perforated plate 13 and is configured such that when the user urinates, part of the urine accumulates in the concave portion 71, the urination can be detected more reliably by the electrode 72. can. Therefore, the perforated plate 13 shown in this figure can be used particularly preferably in the management system of the second embodiment. The concave portion 71 may be provided with an opening for allowing the waste water collected in the concave portion 71 to drop into the discharge port 11C after the washing water is flushed after urination.

When the wastewater remains in the toilet bowl 11, the electrode 54 can more reliably detect the wastewater falling from the opening 73 of the peripheral portion 70 of the perforated plate 13 toward the discharge port 11C. Therefore, the perforated plate 13 shown in this figure can also be suitably used in the management system of the first embodiment.

The processing device 52 and the communication device 53 are provided inside the perforated plate 13 . The perforated plate 13 in this figure is also configured to float on water. Thereby, the communication strength of the communication device 53 can be ensured, and the stability of wireless communication can be improved. In addition, since the power required for communication can be reduced, the battery can be used for a long time.

FIG. 8 shows an example of a toilet room with multiple urinals. In order to regularly clean dirt on the toilet bowl 11 and the discharge port 11C of the urinal 1, flush water is flowed into the urinal 1 from the water supply pipe 15 at a predetermined timing regardless of the state of use of the urinal 1. . In this periodical flushing, flushing water is flushed to the plurality of urinals 1a to 1d at different timings. The detection devices 30a-30d installed in each of the plurality of urinals 1a-1d detect the drainage at different timings in the order in which the wash water is poured into the urinals 1a-1d. Therefore, it can be determined which urinal 1 each of the detection devices 30a to 30d is installed on the basis of the order in which flush water is flushed through the urinals 1a to 1d and the order in which the detection devices 30a to 30d detect drainage. can know. In the regular cleaning, the management device 100 may instruct each of the urinals 1a to 1d to be cleaned, and the instructed urinals 1a to 1d may flush cleansing water. Alternatively, a control device installed in a toilet room or a facility in which the toilet room is installed may instruct each of the urinals 1a to 1d to flush, and the instructed urinals 1a to 1d may flush flush water. . Further, the control device provided for each of the urinals 1a to 1d may flush flush water at a set time.

FIG. 9 shows the configuration of the management device 100 according to the embodiment. The management device 100 includes a communication device 101 , a display device 102 , an input device 103 , a storage device 120 and a control device 110 . The management device 100 may be a server device, a device such as a personal computer, or a mobile terminal such as a mobile phone terminal, a smart phone, or a tablet terminal.

A communication device 101 controls communication with other devices. The communication device 101 receives information from the communication device 53 of the detection device 30 by wireless communication. The communication device 101 may communicate with other devices by any wired or wireless communication method.

The display device 102 displays screens generated by the control device 110 . The display device 102 may be a liquid crystal display device, an organic EL display device, or the like. The input device 103 transmits an instruction input by the user of the management device 100 to the control device 110 . The input device 103 may be a mouse, keyboard, touchpad, or the like. The display device 102 and the input device 103 may be implemented as touch panels.

Storage device 120 stores programs, data, and the like used by control device 110 . The storage device 120 may be a semiconductor memory, hard disk, or the like. The storage device 120 stores a detection information holding section 121, an estimation reference holding section 122, a toilet information database 123, a usage status information holding section 124, and a cleaning status information holding section 125. FIG.

The detection information holding unit 121 holds information received from the detection device 30 . The estimation reference holding unit 122 holds an estimation reference for estimating the discharge state of the waste water from the outlet 11</b>C of the urinal 1 .

The estimation criterion may be a criterion relating to the amount of time that the detection device 30 has continuously detected the presence of waste water. For example, it may be estimated that the outlet 11C or the discharge path is clogged when the time for which the presence of waste water is continuously detected exceeds a predetermined threshold. Further, the degree of clogging of the discharge port 11C or the discharge path may be estimated according to the time during which the presence of waste water is continuously detected.

If the current or resistance is measured by an ammeter, the estimation criterion may be a criterion relating to the measured current or resistance. For example, by identifying whether or not urination is in progress based on the measured current value or resistance value, and subtracting the period of urination from the time during which the presence of waste water was continuously detected, the wash discharged after urination The time until the water is discharged may be calculated, and the discharge state of the waste water may be estimated based on the calculated time. The estimation criteria are the criteria for statistical values such as the average value, maximum value, minimum value, median value, rate of change, average value of rate of change, and rate of change of rate of change calculated from time-series current or resistance values. There may be. The estimation criterion may be a criterion relating to the shape of a waveform that indicates the time change of the current value or the resistance value.

The estimation criterion may be an algorithm that inputs the detection information received from the detection device 30 or the generated information generated from the detection information and outputs the discharge state of the waste water from the outlet 11C of the urinal 1. . This algorithm may be realized by a neural network or the like and learned by machine learning. In machine learning, a set of past detection information or generated information and information indicating the discharge state of waste water at that time may be used as learning data. In this case, when past detection information or generated information is input to the input layer of the neural network, information indicating the discharge state of waste water at that time is output from the output layer of the neural network. Layers may be adjusted.

If there is a correlation between the detection information or the generation information and the water level of the waste water accumulated in the toilet bowl 11, an estimation standard for estimating the water level of the waste water from the detection information or the generation information is estimated based on the correlation. It may be held in the reference holding section 122 . This estimation criterion may be an algorithm that inputs sensed or generated information and outputs the water level of the wastewater. This algorithm may also be realized by a neural network or the like and learned by machine learning. When the above-described floating height detection unit is provided in the urinal 1, the water level of the drainage may be estimated from the information detected by the floating height detection unit.
