[Overview of information processing system 1]
First, an overview of the information processing system 1 according to one embodiment will be described.
FIG. 1 is a diagram for explaining an information processing system 1 according to an embodiment.

The information processing system 1 is a system (number of people estimation system) for estimating the number of people (users) using the facilities in various facilities that use water, such as toilets and washrooms. In the following, a toilet will be described as an example of a facility.
The information processing system 1 includes a measuring device 100 and an information processing device 200.

The measuring device 100 measures water used in each of one or more pieces of equipment installed in a toilet. The equipment may be, for example, a toilet bowl, a urinal, a wash basin (hand wash basin), or the like. The measuring device 100 may detect, for example, the amount of water used in a toilet. The measuring device 100 may detect that water is being used in each facility, for example, by detecting the amount of water.
As an example, the measuring device 100 detects that water is used when water is used in the equipment based on the fact that the user uses the equipment. In this case, the measuring device 100 may detect the use of water in the equipment, for example, based on measuring the amount of water used in the equipment.

The information processing device 200 may be, for example, a computer such as a server, desktop, laptop, tablet, or smartphone. The information processing device 200 is a device (number of people estimating device) that estimates the number of users who use a toilet (facility). That is, the information processing device 200 estimates the number of people using the toilet based on the measurement results by the measurement device 100.
When the information processing device 200 detects water use by the measuring device 100 when a user uses a facility (for example, a toilet, a urinal, a washstand, etc.), the information processing device 200 estimates that the user has used the facility. You may. The information processing device 200 may estimate the number of users of the facility, for example, based on the estimated number of times that the user has used the facility. For example, the information processing device 200 may estimate the number of people using the toilet based on the number of people using one or more facilities provided in the toilet.

Note that the toilet, which is an example of a facility, may be a toilet placed inside a building such as a building, or a toilet placed outdoors such as a park or square. Moreover, the above-mentioned toilet may be, for example, a public toilet, a temporary toilet, or the like.

[Details of information processing system 1]
Next, the information processing system 1 according to one embodiment will be described in detail.
FIG. 2 is a block diagram for explaining the measuring device 100 according to one embodiment.
FIG. 3 is a block diagram for explaining the information processing system 1 and the like according to one embodiment.

[Measuring device 100]
First, details of the measuring device 100 will be explained.
The measuring device 100 measures the amount of water used in each of a toilet bowl, a urinal, and a washstand arranged in a toilet, and generates water amount information regarding the amount of water. Such a measuring device 100 may be, for example, a water meter (water flow meter).
As illustrated in FIG. 2, the measurement device 100 includes, for example, a plurality of water flow sensors 110 and a measurement main body 101.

The water flow sensor 110 measures the amount of water used in the toilet. The water flow sensor 110 includes, for example, a propeller 111 (see FIG. 1) arranged in a pipe through which water flows. That is, the propeller 111 is placed, for example, in a water pipe used in a toilet. For example, when water flows in response to use of water in a toilet, the propeller 111 rotates in accordance with the flow of water. The propeller 111 (water flow sensor 110) may be arranged, for example, in a water pipe connected to each of all the equipment arranged in a toilet (for example, a toilet bowl, a urinal, a washbasin, etc.). That is, the propeller 111 (water flow sensor 110) may be arranged for each piece of equipment, for example.

The measurement main unit 101 acquires the rotation (rotation speed) of the propeller 111 and transmits the acquisition result to the information processing device 200 . Such a measurement main body section 101 may include, for example, a measurement control section 102, a measurement communication section 103, and a clock section 104.

The measurement control unit 102 may be, for example, an arithmetic processing device. The measurement control unit 102 acquires the rotation (number of revolutions) when the propeller 111 rotates according to the amount of water (water flow) flowing through the pipe, and uses the obtained result, that is, the rotation (number of revolutions) of the propeller 111 as water amount information. generate. Note that an example of the water flow information is illustrated in FIG. 4, which will be described later.

The measurement communication unit 103 communicates with the information processing device 200, for example, based on the control of the measurement control unit 102. The measurement communication unit 103 transmits water amount information to the information processing device 200, for example, based on the control of the measurement control unit 102. For example, the measurement communication unit 103 determines, based on the control of the measurement control unit 102, every time the measurement control unit 102 acquires the rotation (rotation speed) of the propeller 111 (the timing at which the propeller 111 shifts from a stopped state to a rotating state). ), or the water amount information may be transmitted to the information processing device 200 at a predetermined timing. The predetermined timing includes, for example, preset timing such as every predetermined time interval, a predetermined time every day, a predetermined time on a predetermined day of the week, and a predetermined time on a predetermined day. Alternatively, it may be at any timing.

One or more measurement main body parts 101 may be arranged for one toilet.
One measurement main unit 101 may be connected to each propeller 111 (water flow sensor 110), or one measurement unit may be connected to each of a plurality of propellers 111 (water flow sensor 110). The measurement main unit 101 can determine which equipment uses water by associating one or more equipment (for example, a toilet, a urinal, a washstand, etc.) with the water flow sensor 110 disposed in each equipment in advance. It is possible to specify which water flow sensor 110 is used, that is, which water flow sensor 110 detects the use of water. The measurement main unit 101 includes, for example, information that specifies which equipment (water flow sensor 110) the water use detection result is (identifies the equipment in which water was used) (for example, the equipment (water flow sensor 110) Water amount information may be generated by associating a unique device number, etc.) with the obtained result of the rotation (rotation speed) of the propeller 111 by the water flow sensor 110.

The measurement main body section 101 may include, for example, a clock section 104, and time information regarding the time measured by the clock section 104 may be included in the water flow information. That is, as an example, the measurement main unit 101 (measurement control unit 102) generates time information (time information), etc. when generating water flow information, that is, when generating information on when water is used in toilet equipment. may be included in the water flow information. As a more specific example, when the measurement control unit 102 obtains a value of "1", which will be described later, such as detection information (ON information) as information when water is used, that is, from "0" to "1". The water flow information may include information on the time when the value changes (time information). Here, as an example, the detection information (ON information) may record a value of "0" when water does not flow, and may record a value of "1" when water flows. That is, as an example, the measurement control unit 102 records a value of "0" when water is not flowing because the propeller 111 is stopped, and records a value of "0" when water is flowing because the propeller 111 is rotating. A value of "1" may be recorded.
In addition, when the information to flow water is set to the value "1" and the information to stop the water is set to "0", the measurement control unit 102 sets the information to flow water to "1" and then obtains the water flow information. If this is not possible, it can be determined that water is not flowing and a malfunction of the equipment can be detected. Similarly, if the measurement control unit 102 is able to obtain water flow information after setting the information to stop the water to "0", it can determine that the water could not be stopped and detect a failure of the equipment.

[Information processing device 200]
Next, details of the information processing device 200 will be explained.
As illustrated in FIG. 3, the information processing device 200 includes, for example, a communication section 211, a storage section 212, a display section 213, a control section 201, and the like. The communication unit 211, the storage unit 212, and the display unit 213 may be an embodiment of an “output unit”. The control unit 201 may function as, for example, a reception unit 202, an acquisition unit 203, an estimation unit 204, a calculation unit 205, an output control unit 206, and the like.
The control unit 201 may be configured by, for example, an arithmetic processing unit of the information processing device 200. The control unit 201 (e.g., arithmetic processing unit, etc.) reads out and executes various programs stored in the storage unit 212, etc. as appropriate, thereby controlling each unit (e.g., the reception unit 202, the acquisition unit 203, the estimation unit 204, The functions of the calculation unit 205, output control unit 206, etc.) may also be realized.

The communication unit 211 communicates with a device outside the information processing device 200 (external device). The external device may be, for example, the measurement device 100, the server 301, the user terminal 302, etc. As an example, the communication unit 211 may receive water flow information transmitted from the measuring device 100. As an example, the communication unit 211 may control at least one of the estimation result of the estimation unit 204 and the calculation result of the calculation unit 205 (described later) based on the control of the output control unit 206 (described later). at least one selected among them) may be transmitted to an external device (for example, server 301, user terminal 302, etc.).
The server 301 may be, for example, a device that is placed outside the information processing device 200 and has a storage area for information and the like.
The user terminal 302 may be, for example, a terminal used by a user of the information processing system 1. User terminal 302 may be, for example, a desktop, laptop, tablet, smartphone, etc.

The storage unit 212 stores, for example, various information and programs. An example of the storage unit 212 may be a memory, a solid state drive, a hard disk drive, or the like. As an example, the storage unit 212 stores at least one of the estimation result of the estimation unit 204 and the calculation result of the calculation unit 205 (at least one selected from the group of the estimation result and the calculation result) based on the control of the output control unit 206. 1) may be memorized.

The display unit 213 displays, for example, characters, symbols, images, and the like. As an example, the display unit 213 displays at least one of the estimation result of the estimation unit 204 and the calculation result of the calculation unit 205 (at least one selected from the group of the estimation result and the calculation result) based on the control of the output control unit 206. 1) may be displayed.

The reception unit 202 receives water flow information regarding the flow of water used in the toilet. The reception unit 202 receives water flow information transmitted from the measurement device 100, for example, via the communication unit 211.

Based on the water amount information received by the reception unit 202, the acquisition unit 203 determines the first point in time when water is used in each of the toilet bowl and urinals arranged in the toilet, and the first point in time when water is used in the washbasin arranged in the toilet. A second point in time may also be acquired.
For example, the acquisition unit 203 acquires the time when water is used in each of the toilet bowl and the urinal (for example, the time when ON information is recorded) based on the time information recorded in the water flow information. The time point may be acquired as one point in time, and the time when water is used in the sink (for example, the time when ON information is recorded) may be acquired as the second point in time.
Alternatively, the acquisition unit 203 uses a timing device such as a timer to determine when the water flow information is generated by the measuring device 100 corresponding to each of the toilet bowl and urinal, that is, when water flow information is generated in each of the toilet bowl and urinal. Timing starts when water is used (first time point), and then ends when water flow information is generated by the measuring device 100 corresponding to the sink, that is, until water is used in the sink. (second time point) may be acquired. In this case, the water flow information generated by the measuring device 100 may be transmitted to the information processing device 200 in real time, for example, or may not be transmitted to the information processing device 200 in real time.

The acquisition unit 203 acquires the first point in time when water is used in each of the toilet bowl and urinal arranged in the toilet, and the toilet bowl or urinal that acquires the first point in time, based on the water flow information received by the reception unit 202. and a third time point after the first time point when water is used in the same toilet bowl or urinal.
The acquisition unit 203 may acquire, for example, the timing at which water is used in the same toilet bowl and in the same urinal, respectively. In this case, the acquisition unit 203 may acquire the first timing when water is used in each of the toilet bowl and the urinal as the first time point, for example, based on time information recorded in the water flow information. Next, the acquisition unit 203 may acquire, for example, a second timing when water is used in each of the same toilet bowl and urinal as the toilet bowl from which the first time point was acquired, as the third time point.
Alternatively, the acquisition unit 203 uses a timing device such as a timer to determine when the water flow information is generated by the measuring device 100 corresponding to each of the toilet bowl and urinal, that is, when water flow information is generated in each of the toilet bowl and urinal. Timing starts from the time of use (first time point), and thereafter, when water flow information is generated by the measuring devices 100 corresponding to the same toilet and the same urinal, that is, when the same toilet and the same urinal The time until water is used in each urinal and the time measurement ends (third time point) may be acquired. In this case, the water flow information generated by the measuring device 100 may be transmitted to the information processing device 200 in real time, for example, or may not be transmitted to the information processing device 200 in real time.

The estimation unit 204 may estimate the number of people who used the toilet based on the water flow information received by the reception unit 202.
For example, when water usage is recorded in the water flow information, the estimation unit 204 determines that the user used toilet facilities (for example, a toilet bowl, a urinal, a washstand, etc.) corresponding to the water usage. It may be estimated. That is, the estimating unit 204 may estimate that one person used the toilet, for example, in response to one use of water at the toilet facility. In other words, as an example, when the water flow information includes detection information (ON information) indicating that water use has been detected, the estimation unit 204 estimates the number of people according to the number of detections based on the detection information (ON information). You may. If the ON information is recorded in the water flow information, the estimating unit 204 may estimate that the user used the toilet facilities in accordance with the ON information. That is, the estimating unit 204 may estimate that one person used the toilet for each ON information, for example.

In addition, as an example, the estimating unit 204 calculates the unit amount of water (unit amount of water based on unit water amount information) used at one time in each of the toilet bowl, urinal, and wash basin arranged in the toilet, and the receiving unit 202. The number of people who used the toilet may be estimated based on the amount of water used based on the received water amount information.
The above-mentioned measuring device 100 may include ON information in the water amount information, for example, when water is used in toilet facilities. As an example, the measuring device 100 may record continuous ON information when the water in the toilet is flushed (when the water continues to flow) in the water flow information.
For example, the flow rate of water in toilet facilities (for example, the amount of water per unit time) can be assumed to be constant. In this case, the estimating unit 204 can estimate the amount of water (water amount) used in the toilet facilities, for example, based on the water amount information and the assumption that the flow rate of water is constant.
Therefore, the estimating unit 204 calculates, for example, the amount of water used (amount of water) of each toilet facility (toilet bowl, urinal, washstand, etc.) acquired based on the water amount information, for each facility based on the unit water amount information. It is possible to estimate the number of users of each facility by dividing by the amount of water per use (unit water amount).

If the time from the first time point to the second time point acquired by the acquisition unit 203 is less than or equal to a first threshold value set in advance, the estimation unit 204 determines whether the person who used the toilet bowl or urinal in the toilet and the person who used the toilet bowl It may be assumed that the person who used the washstand is the same person. The first threshold is, for example, the time from when a user of a toilet or urinal finishes using the toilet or urinal until he moves to the sink and uses it again, for example to wash his hands. It may be. The first threshold value may be set in advance, for example, by conducting experiments, predictions, etc. for each toilet.

For example, if the time from the first time point to the second time point is less than or equal to the first threshold value, the estimating unit 204 estimates that the user of the toilet bowl or urinal has used the washbasin continuously, and It may be assumed that the user of the toilet bowl and the user of the washstand are the same person. In this case, if the time from the first time point to the second time point is less than or equal to the first threshold, the estimating unit 204 determines whether the user of the toilet or urinal (one person) and the user of the sink (one person) It may be assumed that there is only one person using the toilet, assuming that they are the same person.

On the other hand, if the time from the first point in time to the second point in time exceeds the first threshold, the estimation unit 204 estimates that the user of the toilet bowl or urinal and the user of the washbasin are different people. You may. In this case, if the time from the first point in time to the second point in time exceeds the first threshold, the estimating unit 204 determines whether the user of the toilet or urinal (one person) and the user of the sink (one person) It is also possible to estimate that there are two people using the toilet by estimating that they are different people.

If the time from the first time point to the third time point acquired by the acquisition unit 203 is less than a second threshold value set in advance, the estimation unit 204 determines whether the toilet bowl or urinal is used at both the first time point and the third time point. It may be assumed that the people who used the are the same person. The second threshold value may be, for example, the time from when the user of the same toilet or the same urinal flushes the water for the first time until the user flushes the water for the second time. The second threshold value may be set, for example, by performing experiments, predictions, etc. in advance.

For example, if the time from the first time point to the third time point is less than the second threshold, the estimating unit 204 estimates that the user of the toilet or urinal has flushed water multiple times in a row, It may be assumed that the user of the toilet bowl or urinal at the first time point and the user of the same toilet bowl or urinal at the second time point are the same person. In this case, if the time from the first time point to the third time point is less than the second threshold, the estimation unit 204 determines that the user (one person) corresponding to the first time point and the user (one person) corresponding to the third time point It may be assumed that there is only one person using the toilet.

In this case, the estimating unit 204 can estimate that the same person is the same person even if the same person flushes water three or more times in a row in the same toilet bowl or the same urinal. In other words, as an example, the estimating unit 204 determines that the time from the time when water is flushed for the first time (first time point) to the time when water is flushed for the second time (third time point) is less than the second threshold, and , if the time from the second time (third time point) to the third time (fourth time point) is less than the second threshold, the first to third water flows are performed. It may be assumed that the users who have done so are the same person. That is, the estimating unit 204 may estimate that the number of users who flushed water for the first to third times is one.
Note that, for example, even when water is flushed for the fourth time or more, the estimation unit 204 may estimate whether or not it is the same person based on the second threshold value in the same manner as described above.

On the other hand, if the time from the first time point to the third time point is equal to or greater than the second threshold value, the estimating unit 204 determines that the user of the toilet or urinal is the user of the toilet or urinals the first time, and the user of the same toilet is the user of the urinal the second time. It may be assumed that the user of the toilet or urinal is a different person. In this case, if the time from the first time point to the third time point is equal to or greater than the second threshold, the estimation unit 204 determines whether the user of the toilet or urinal (one person) and the user of the same toilet or urinal It is also possible to estimate that there are two people using the toilet by estimating that the person is different from (one person).

Here, the user of the toilet or urinal may flush the toilet or urinal several times, and then use the sink. In this case, the estimating unit 204 replaces the first time point with a third time point (fourth time point), and determines that the time from the third time point acquired by the acquisition unit 203 to the second time point is equal to or less than a first threshold value set in advance. In some cases, it may be assumed that the person who used the toilet bowl or urinal in the toilet and the person who used the washbasin in the toilet are the same person.

The calculation unit 205 calculates the toilet usage rate per unit time based on the number of people estimated by the estimation unit 204. The calculation unit 205 may, for example, total the number of people estimated by the estimation unit 204. In this case, the calculation unit 205 may, for example, total the number of people for a predetermined period. The predetermined period may be various periods including, for example, 1 hour, 6 hours, 12 hours, 1 day, 7 days, 10 days, 1 month, 3 months, 4 months, and 6 months. That is, the calculation unit 205 may total the number of people who used the toilet in a predetermined period based on the number of people estimated by the estimation unit 204, for example. The calculation unit 205 may calculate the usage rate of the toilet according to the number of people using the toilet per unit time, for example, based on dividing the number of people counted for each predetermined period by the unit time. The unit time may be various times such as 1 hour, 1 day, 1 month, 3 months, 4 months, and 6 months. The unit time may be, for example, taking into account a predetermined period, that is, a time shorter than the predetermined period.

For example, the output control unit 206 may control the output unit to output the number of people estimated by the estimation unit 204. Further, the output control unit 206 may control the output unit to output the number of people totaled by the calculation unit 205 (the number of people for a predetermined period) based on the number of people estimated by the estimation unit 204, for example. Furthermore, the output control unit 206 may control the output unit to output the utilization rate calculated by the calculation unit 205, for example. An embodiment of the output section may be the communication section 211, the storage section 212, the display section 213, etc.
That is, the output control unit 206 may control the communication unit 211 to transmit at least one of information regarding the number of people and information regarding the utilization rate to the outside (external device), for example. The external devices may be, for example, the server 301 and the user terminal 302.
Further, the output control unit 206 may control the storage unit 212 to store at least one of information regarding the number of people and information regarding the utilization rate, for example.
Further, the output control unit 206 may control the display unit 213 to display at least one of the number of people and the utilization rate, for example.

Here, for example, when the toilet usage rate per unit time calculated by the calculation unit 205 is equal to or higher than a third threshold value set in advance, the output control unit 206 outputs the estimation result of the estimation unit 204 and the calculation of the calculation unit 205. The output unit is controlled to output at least one of the results.
Various values can be set for the third threshold. As an example, the third threshold value may be the number of users expected in advance when installing the toilet (estimated usage rate), or a value lower by a predetermined percentage than the expected number of users (estimated usage rate) (for example, The usage rate may be any percentage lower than the expected utilization rate, such as 30%, 20%, 10%, etc.).
That is, for example, when the usage rate of the toilet per unit time is equal to or higher than the third threshold (when the usage rate of the toilet per unit time is relatively high), the output control unit 206 controls at least one of the number of people and the usage rate. The output unit may be controlled to output. The output unit may be, for example, the communication unit 211, the storage unit 212, the display unit 213, etc., as described above. When the usage rate of the toilet per unit time is equal to or higher than the third threshold (when the usage rate of the toilet per unit time is relatively high), the output control unit 206 controls the number of people and the usage rate as in the case described above. At least one of the communication section 211, the storage section 212, and the display section 213 may be controlled to output at least one of them.
The number of people may be, for example, the number of people estimated by the estimation unit 204. Further, the number of people may be, for example, the number of people totaled by the calculation unit 205 based on the number of people estimated by the estimation unit 204 (the number of people for a predetermined period). The utilization rate may be, for example, a utilization rate calculated by the calculation unit 205.

[Example]
Next, an example of this embodiment will be described.

<Toilet accommodation status>
The information processing apparatus 200 registers the information in advance in the storage unit 212 or the like in order to grasp the accommodation status of each toilet (for example, a public toilet, etc.) for each facility. That is, the information processing device 200 includes, for example, a men's urinal (men's large), a men's urinal (men's small), a men's washstand (men's hand wash), a women's urinal (women's large), a woman's washstand. The storage unit 212 may store the installed number of each piece of equipment such as (female hand wash), multi-purpose toilet bowl (multiple hand wash), and multi-purpose toilet washbasin (multi-hand wash), as well as equipment numbers that identify each piece of equipment. Further, the information processing device 200 may store, in the storage unit 212, an equipment number that identifies which toilet it is, for example, since the accommodation status (such as the number of installed equipment arranged in each toilet) differs from toilet to toilet. .

<Handling of input information>
As an example, the information processing device 200 receives various types of information (for example, water flow information) from the toilet (measuring device 100) at one-minute intervals, and performs various processes using the reception of the information as a trigger. For example, the information processing device 200 uses real time (the time when water is actually used in each facility stored in the information (usage time)) as the time used when performing various processes. As an example, the information processing device 200 receives the following information (1) to (4) (eg, water flow information). For example, the information processing device 200 receives the information (1) at 10:01:00, and the information includes that the urinal 2 for men (male elementary school 2) is empty at 10:00:50. is recorded as being used.

<Toilet configuration>
This embodiment will be described using a men's restroom (two men's toilets, three men's urinals, and two men's sinks) as an example of restroom equipment.
Note that actual toilets include, for example, women's toilets and multi-purpose toilets, but the information processing algorithm is the same as that for men's toilets, which will be described later. Here, the wash basins are considered to be arranged in each of the men's toilet, the women's toilet, and the multipurpose toilet, and the men's wash basin is attached to the men's toilet. Similarly, women's washbasins are attached to women's restrooms. Similarly, a multi-purpose wash basin is attached to a multi-purpose toilet.

<Overview of information processing algorithms>
(1) Algorithm for detecting flushing multiple times in one use of toilet facilities (urinal or urinal) A toilet user may flush multiple times after using a toilet bowl, urinal, or wash basin. Water may flow continuously. In this case, when water is used in the same toilet (toilet or urinal) or the same sink within a certain period of time (within a preset threshold), the information processing device 200 of water, and limit the number of times you use the toilet or wash basin to one time.

(2) Algorithm that links the use of toilet facilities (urinal or urinal) and the use of hand washing (sink) Toilet users wash their hands after using the toilet (urinal or urinal). There are many things. The information processing device 200 registers in advance in the storage unit 212 the time from when the toilet (toilet or urinal) is used to when the hand is washed (the time that is the threshold for determining the use) as the "hand washing deadline time". put. If the time when the toilet user uses the washbasin (actual hand washing time) is within the pre-registered "hand washing deadline time", the information processing device 200 is configured to perform a Determine that it is hand washing and record the time when hand washing was performed. On the other hand, if the time when the toilet user uses the washbasin (actual handwashing time) exceeds the "handwashing deadline time", the information processing device 200 allows the toilet user to use only the washbasin. It is determined that the use is limited to
When a plurality of toilets (toilet bowls or urinals) are used at the same time or approximately the same time, the information processing device 200 uses ""Handwashing deadline time" may be set for each toilet (urinal or urinal). In this case, the information processing device 200 compares the time when the toilet user uses the washbasin (actual hand washing time) and the multiple registered "hand washing deadline times", and selects the "hand washing deadline time" first. Select too many equipment. Then, the information processing device 200 records the "hand washing performance time" as hand washing corresponding to the use of the toilet (toilet or urinal).

<Details of information processing>
(1. Received data)
The information processing device 200 receives, for example, the following information.
・Time in received data: T = xx year xx month xx day xx hour xx minute xx seconds (time stamp)
・Equipment numbers: MB1 (Male high school 1), MB2 (Male high school 2), MS1 (Male high school 1), MS2 (Male high school 2), MS3 (Male high school 3), MW1 (Male hand washing 1), MW2 (Male hand washing 2)
In addition, if the number of women's restrooms and multipurpose restrooms increases, WB1 (Women's University 1), WB2 (Women's University 2), WB3 (Women's University 3), WB4 (Women's University 4), WW1 (Women's Hand Washing 1), WW2 The types of equipment may be increased, such as (female hand washing 2), TB1 (multiple hand washing 1), and TW1 (multiple hand washing 1).

(2. Event table triggered by received data)
For example, when the information processing device 200 receives information (for example, data such as water flow information) every minute, it registers various information according to an algorithm. Note that a detailed example of this process will be described later.

(3. Counter)
The information processing device 200 sets the initial value of the toilet/hand washing counter UC to 0. The usage counter UC of each facility (toilet, urinal, and washstand) is used to estimate the case where each facility is used multiple times by the same user.

(4. Various registration times)
For example, the information processing device 200 sets the registration time of each facility (toilet, urinal, and washstand) as follows.
・Usage time of toilet and hand washing (each facility): UT (time stamp)
・Hand washing deadline time: ET (time stamp)
・Hand washing time: FT (time stamp)
The registration time may be changeable depending on the usage situation.

(5. Various constants)
The information processing device 200 sets, for example, the following time as the time for detecting the case where each facility is used multiple times (multiple usage detection time) (second threshold). The multiple use detection time (second threshold) is the time for determining whether the equipment has been flushed with water only once or whether the equipment has been flushed with water multiple times.
・MBD=180 (Men's toilet 180 seconds)
・MSD=60 (Male urinal 60 seconds)
・MWD=10 (Men's washbasin 10 seconds)
・WBD=240 (Women's toilet 240 seconds)
・WWD=10 (Women's washbasin 10 seconds)
・TBD=300 (Multi-purpose toilet bowl 300 seconds)
・TWD=10 (Multi-purpose toilet sink 10 seconds)
Various constants may be changeable depending on usage conditions.

Further, the information processing device 200 sets, for example, the following time as the time from using the toilet bowl or urinal to using the wash basin (time until hand washing) (first threshold).
・MBW=120 (men's toilet 120 seconds)
・MSW=30 (male urinal 30 seconds)
・WBW=180 (women's toilet 180 seconds)
・TBW=240 (Multi-purpose toilet bowl) 240 seconds)

(6. Processing when receiving information (receiving water flow data))
The information processing device 200 identifies the toilet equipment used (toilet (large urinal, small urinal) or sink) based on the equipment number of the received data.
The information processing device 200 stores device numbers (for example, MB1, MB2, MS1, MS2, MS3, MW1, MW2, etc.) in the storage unit 212.

(7. When toilet water flow is detected)
First, a case where the toilet is used will be explained. Here, a case will be described in which a toilet bowl in a men's restroom (equipment number = MB1: men's room 1) is used.
When the information processing device 200 receives the water flow information (data) corresponding to MB1, it registers the usage time UT of the toilet (MB1) recorded in the water flow information. The information processing device 200 registers the time until hand washing corresponding to the usage time UT (first threshold value as the hand washing deadline time ET), and sets the usage counter UC of the toilet (MB1) to "1". Here, the toilet usage counter UC assumes that there is no previously registered MB1, that is, when MB1 is used for the first time. That is, the information processing device 200 registers the following information.
・Usage time UT: T (xx year, xx month, xx day, xx hour, xx minute, xx second)
・Hand washing deadline time ET: T (Usage time UT (xx year, xx month, xx day, xx hours, xx minutes, xx seconds) + MBW (time until hand washing (first threshold): 120 seconds))
・Usage counter UC: 1

On the other hand, the information processing device 200 sets the usage counter UC of MB1 to "2" if there is one previously registered in the usage counter UC of the toilet (MB1) and the following formula (1) is satisfied. . In this case, the information processing device 200 considers the MBD (second threshold) to be “used multiple times” if it is less than 180 seconds.
(MB1 usage time UT (T)) - (Usage time UT (T) of the previous registered MB1) < (MBD (second threshold for men's university: MBD = 180 seconds))... (1 )
Then, the information processing device 200 rewrites the hand washing deadline time ET of the previously registered MB1 to 00:00:00.
Note that the information processing device 200 ends the process when the following formula (2) is satisfied.
(MB1 usage time UT (T)) - (Usage time UT (T) of the previous registered MB1) ≧ MBD (second threshold for men's university: MBD = 180 seconds)... (2)

(8. When hand washing water flow is detected)
Next, the case of hand washing will be explained. Here, a case will be described in which a washbasin (equipment number=MW1 (men's washroom 1)) in a men's restroom is used.

When the information processing device 200 receives the water flow information (data) corresponding to MW1, it registers the usage time UT of the equipment (MW1) recorded in the water flow information, and sets the washbasin usage counter UC to "1". do. Note that here, the usage counter UC of the wash basin (MW1) is assumed to be set when there is no previously registered MW1, that is, when MW1 is used for the first time. That is, the information processing device 200 registers the following information.
・Usage time UT: T (xx year, xx month, xx day, xx hour, xx minute, xx second)
・Usage counter UC: 1

Here, the information processing device 200 identifies the toilet bowl or urinal that corresponds to the use of the wash basin (MW1) by specifying the hand washing deadline time ET for using the toilet (urinal or urinal) as the new equipment at the time. Equipment that expires first among those within the hand-washing deadline (hand-washing deadline time ET-MW1 usage time UT (T) > 0) (large) (A) The information processing device 200 registers the usage time UT (T) of the wash basin MW1 in the hand washing implementation time FT of the specified equipment (toilet or urinal).
Note that the information processing device 200 does not process other equipment (toilet or urinal) whose time limit has not expired.

In the case where all of the above-mentioned hand-washing deadlines have expired (there is no user waiting to wash their hands in the restroom) (equipment where the hand-washing deadline has been exceeded with ET-T≦0), the information processing device 200 uses the washbasin MW1. The usage time UT(T) of MW1 is registered in the hand washing implementation time FT. In other words, in this case, only hand washing is performed.

On the other hand, the information processing device 200 sets the counter UC of the washstand MW1 to "2" if there is a washstand MW1 that was registered immediately before the above-mentioned hand-washing period and the following formula (3) is satisfied. In this case, the information processing device 200 considers it to be “used multiple times” if the MWD as the second threshold is less than 10 seconds.
(Usage time UT (T) of MW1) - (Usage time UT (T) of the previous registered MW1) < MWD (Second threshold for men washing their hands: MWD = 10 seconds)... (3)

When the following formula (4) is satisfied, the information processing device 200 scans the handwashing expiration time ET for using the toilet in order from the equipment with the latest time, and selects the equipment (toilet or urinal) that is within the handwashing expiration date first. ), the following process is performed (A).
(Usage time UT (T) of MW1) - (Usage time UT (T) of the previous registered MW1) ≧ MWD (Second threshold for men washing their hands: MWD = 10 seconds)... (4)

That is, as the above-mentioned process, the information processing device 200 performs the above-mentioned process at the hand-washing implementation time FT of the equipment that is the first to expire among the hand-washing deadlines (ET-T > 0 which is the first to expire among the hand-washing deadlines). The usage time UT(T) of the wash basin MW1 is registered.
Note that the information processing device 200 does not perform processing on other equipment whose time limit has not expired.

If all the handwashing deadlines corresponding to the equipment (toilet or urinal) have expired (there are no users waiting to wash their hands in the restroom), the information processing device 200 determines that the handwashing deadline has expired (ET-T≦0). For the equipment that exceeded the limit, the usage time UT of the wash basin MW1 is registered in the hand washing execution time FT of the wash basin MW1.In other words, in this case, only hand washing is performed.

Here, as an explanation of the equipment whose hand washing time limit expires first in (A) above, for example, when the use time UT (T) of MW1 (men's hand washing 1) is 11:02:50, If the hand-washing deadline time ET for MB1 (1st male high school student) is 1:04:00 and the hand-washing deadline time ET for MS1 (1st male elementary school student) is 11:03:30, the equipment whose time ET passes first is Since MS1 (male elementary school 1) is MS1 (male elementary school 1), the information processing device 200 selects MS1 (male elementary school 1).

In addition, when using the facilities (urinals and urinals), if the toilet is used first and then the urinal is used, the order of hand washing after that is that the user of the toilet should first use the urinal, then the urinal should be used. Users do not always wash their hands in order. In other words, the order of hand washing may be reversed. If each of a plurality of facilities (a toilet bowl and a urinal) is used once, the hand washing deadline time ET after use of each facility is registered for each of the plurality of facilities. Therefore, the information processing device 200 can correctly grasp the number of times of hand washing because if each hand washing is completed within the hand washing deadline time ET, the hand washing will be performed twice in total.

(9. Number of toilets used, number of hand washes used, hand washing rate, etc.)
(a) Number of users We will explain how to count the number of toilet users.
For example, the information processing device 200 sets a unit time, totals each category in the unit time, and obtains the number of toilet uses.
As an example, the information processing device 200 selects the men's toilet 1 (Men's Large 1 (MB1)) and totals the unit time counter UC=1, thereby allowing the user of the men's toilet 1 (CMB1 ( It is possible to obtain the number of users of the University of Tokyo (Men's University).
The information processing device 200 can similarly obtain the number of users for the male urinal 2 (MB2) and the male urinals 1 to 3 (MS1 to 3).

Further, the information processing device 200 sets, for example, a unit time, totalizes each category in the unit time, and obtains the number of uses of the toilet and washstand.
As an example, the information processing device 200 selects the men's toilet 1 (MB1) and totals the counter UC=1 and the hand washing time FT is registered, thereby selecting the men's toilet 1. It is possible to obtain the number of users who used the service and washed their hands (CMBW1 (number of hand washes per men's school)).
The information processing device 200 can similarly obtain the number of users who washed their hands with respect to the men's urinal 2 (MB2) and the men's urinals 1 to 3 (MS1 to 3).

Further, the information processing device 200 sets a unit time, aggregates each category in the unit time, and obtains the number of uses of only the washbasin, for example.
As an example, the information processing device 200 selects the men's wash basin 1 (MW1) and totals the counter UC=1 and the hand washing time FT is registered. It is possible to obtain the users (CMW1 (number of men washrooms 1 only)).
The information processing device 200 can similarly obtain the number of users who only wash their hands at the men's wash basin 2 (MW2).

(b) Toilet usage level We will explain how to calculate the level of toilet usage.
The information processing device 200 sets a "threshold" for the number of toilet uses mentioned above in a certain period of time, and when the threshold is exceeded, the usage is determined to be "high", and when it is below the threshold, the usage is determined to be "high". It is also possible to say "low". Examples of the threshold values may be, for example, the number of male urinal users per 60 minutes is 10, and the number of male urinal users per 60 minutes is 50.

(c) Hand-washing rate We will explain how to calculate the hand-washing rate in toilets.
The information processing device 200 calculates the hand washing rate from the number of toilet uses and the number of hand washing uses in a certain period of time.
As an example, the information processing device 200 may calculate the hand washing rate MBR of the user of the men's toilet by dividing the above-mentioned CMBW(n) by CMB(n). Here, n may be information for identifying the toilet (the number of toilets) (n=1, 2), or the like.
Similarly, the information processing device 200 may calculate the hand washing rate MSR of men's urinal users by dividing the above-mentioned CMSW(n) by CMS(n). Here, n may be information for identifying urinals (number of urinals) (n=1, 2, 3), or the like.
The information processing device 200 can also calculate the hand washing rate of each of the women's toilet and the multipurpose toilet in the same manner as described above.
The information processing device 200 may calculate the hand washing rate WBR of the user of the women's toilet by dividing the above-mentioned CWBW(n) by CWB(n). Here, n may be information for identifying toilet bowls (number of toilet bowls) (n=1, 2, 3, 4), or the like.
The information processing device 200 may calculate the hand washing rate TBR of the user of the multipurpose restroom by dividing the above-mentioned CTBW(n) by CTB(n). Here, n may be information for identifying toilet bowls (number of toilet bowls) (n=1), or the like.

<Generation of event table>
Next, a method for generating the above-mentioned event table will be explained.
FIG. 4 is a diagram for explaining an example of the timing of generation of water flow information.
5 to 10 are first to sixth diagrams for explaining an example of an event table.
5 to 10 are event tables generated based on the water flow information in FIG. 4. 5 to 10 show changes (transitions) in the event table in the same toilet.

First, when the information processing device 200 receives water flow information (payload) from the measurement device 100, it generates a table (event table) as illustrated in FIGS. 5 to 10 based on the water flow information. Here, the information processing device 200 assigns item numbers (here, item numbers 1 to 13) in the order in which water flow information (payload) is received from the measuring device 100 and records them in the event table in order.

Here, the information processing device 200 may count the use of toilet facilities (toilet bowl, urinal, and washstand) as follows. That is, the information processing device 200 may extract the usage counter UC corresponding to each equipment as 1 for the equipment usage count. The information processing device 200 counts the number of times the user washes their hands after using the toilet (toilet or urinal) when the toilet (urinal or urinal) usage counter UC is 1 and the hand washing time FT is 1. Registered equipment may also be extracted. The information processing device 200 may extract facilities with a hand-washing counter UC of 1 regarding the use of hand-washing (use of the sink). The information processing device 200 may extract equipment in which the hand washing counter UC is 1 and the hand washing implementation time FT is registered for use only for hand washing (use only the wash basin).

[Information processing method]
Next, an information processing method according to an embodiment will be described.
FIG. 11 is a flowchart for explaining an information processing method according to an embodiment.

In step ST101, the reception unit 202 receives water flow information regarding the flow of water used in the toilet. That is, the reception unit 202 may receive, for example, water flow information generated based on the measurement device 100 detecting that water is used in each toilet facility via the communication unit 211.

In step ST102, the acquisition unit 203 acquires a first point in time when water is used in each of the toilet bowl and urinal arranged in the toilet, and the toilet bowl that acquires the first point in time, based on the water flow information received in step ST101. Alternatively, a urinal and a third time point after the first time point when water is used in the same toilet bowl or urinals are obtained.

In step ST103, the acquisition unit 203 determines, based on the water amount information received in step ST101, the first point in time when water is used in each of the toilet bowl and urinals arranged in the toilet, and the water in the washbasin arranged in the toilet. and the second point in time when it was used.

In this case, as an example, if the water flow information includes detection information (ON information) indicating that water use has been detected, the estimation unit 204 estimates the number of people according to the number of detections based on the detection information (ON information). You may. As an example, the estimating unit 204 may estimate that one person used the toilet per ON information.

Alternatively, as an example, the estimating unit 204 divides the amount of water used based on the water amount information received in step ST101 by the unit amount of water used at one time for each of the equipment installed in the toilet, thereby calculating the amount of water used by the users of the toilet. You may estimate the number of people. In this case, for example, the water amount information may include a device number that specifies the equipment (eg, toilet bowl, urinal, washstand, etc.) where water was used. That is, the estimating unit 204 may, for example, identify the equipment that uses water among a plurality of types of equipment based on the equipment number, and identify the unit water amount according to the identified equipment.
