<First Embodiment>
Next, modes for carrying out the present invention will be described with reference to the drawings.

  Reference numeral 1 shown in FIG. 1 indicates a hand washing monitoring system as a whole. The hand-washing monitoring system 1 includes an electrolyzed water supply device 2, a monitoring information transmitting device 3, an ID (Identification) device 4, a totaling device 5, a supply information transmitting device 6, and a camera device 7. In FIG. 1, monitoring information transmitters 3A to 3B and supply information transmitters 6A to 6B are installed for the two electrolyzed water supply devices 2A to 2B, respectively. Further, the ID devices 4 (4A to 4B in the figure) are worn by all workers, and there are as many workers as there are workers.

  As shown in FIG. 2, the hand-washing monitoring system 1 is assumed to be used in, for example, a factory that handles food and the like. In FIG. 2, one working room in the factory is shown. The electrolyzed water supply device 2 and the monitoring information transmission device 3 are arranged in the vicinity of the hand washing place 9 in the factory and supply hand washing water to the hand washing place 9.

  A waiting line 11 waiting for the order of hand washing is drawn on the floor near the hand washing place 9, and the worker stands by outside the waiting line 11 when viewed from the hand washing place 9. Therefore, in the hand washing area 10, only an operator who is doing hand washing, an operator who moves to go to the hand washing area 9 to perform hand washing, and an operator who moves to leave the hand washing area 10 after finishing hand washing. Will exist.

  As shown in FIG. 3, in the electrolyzed water supply apparatus 2, a control unit 21 including an MPU (Micro Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown) is provided in the electrolyzed water supply apparatus 2. It is designed to control the whole system.

  For hygiene reasons, the sensor 22 is preferably a non-contact type such as infrared rays. For example, the sensor 22 supplies a hand washing request signal to the control unit 21 when the user senses the user's hand washing request by holding his / her hand in front of the sensor 22.

  When the control unit 21 receives the hand washing request signal from the sensor 22, the control unit 21 starts discharging the hand washing water from the electrolytic water storage unit 25.

  Specifically, the control unit 21 causes the discharge unit 26 to discharge the electrolytic water for hand washing (hereinafter, referred to as water for hand washing) by supplying a discharge start signal to the electrolytic water storage unit 25. Moreover, the control part 21 will supply a supply stop signal to the electrolyzed water storage part 25, if the water for hand washing is supplied over the preset supply time. Thereby, the electrolyzed water supply device 2 supplies the hand-washing water for the preset supply time.

  Further, the control unit 21 monitors the remaining amount of the hand-washing water in the electrolyzed water storage unit 25, and supplies a production request signal for producing electrolyzed water to the electrolyzed water production unit 24 when the hand-washing water falls below a predetermined amount. To do.

  The raw material liquid storage unit 23 is connected to the electrolyzed water generating unit 24. The raw material liquid storage section 23 stores the electrolyzed water raw material solution and supplies the electrolyzed water raw material solution to the electrolyzed water generating section 24. By using not the tap water but the adjusted electrolytic water raw material liquid as the undiluted solution of the electrolytic water, it is possible to prevent the calcification of the electrodes and the pipes without installing a filter, and it is possible to downsize the electrolytic water supply device 2.

  As the electrolyzed water raw material liquid, it is preferable to use one containing chlorine as a part or all of the electrolyte in order to generate hypochlorous acid. Preferably, an aqueous solution obtained by mixing sodium chloride and hydrochloric acid, an aqueous sodium chloride solution, hydrochloric acid, potassium chloride or the like is used alone or in combination. This is for maintaining a pH at which the content of hypochlorous acid is stabilized.

  It is also possible to use alkaline electrolyzed water as water for hand washing. In this case, as the electrolyzed water raw material liquid, for example, an aqueous solution containing sodium such as sodium hydrogen carbonate, sodium carbonate or sodium hydroxide, or an aqueous solution containing potassium such as potassium carbonate or potassium hydroxide is preferably used. Of course, it is also possible to mix and use acidic electrolyzed water and alkaline electrolyzed water.

Further, the electrolyzed water raw material liquid in the present embodiment may contain fine gas bubbles of a regulating gas having a regulating function of improving the existing amount of hypochlorous acid. For example, by using oxygen gas (O ₂ ) or ozone gas (O ₃ ) as the adjusting gas, the oxidation of chlorine can be promoted, and as a result, the existing amount of hypochlorous acid in the electrolyzed water can be improved. ..

Further, by using chlorine gas (Cl ₂ ) as the adjusting gas, the chlorine content in the electrolyzed water raw material liquid can be increased, and as a result, the existing amount of hypochlorous acid in the electrolyzed water can be improved. .. Further, by using hydrogen gas (H ₂ ) as the adjusting gas, it is possible to easily control the pH of the electrolyzed water within the range of 2.7 to 6.5.

  The fine bubbles are so-called fine bubbles having a size of less than 1 μm, and can be stably present in the electrolytic water raw material liquid for several months or more. Further, in place of the electrolyzed water, nanobubble water containing fine bubbles, water having a bactericidal / aroma / moisturizing effect, tap water, etc. can be used as water for hand washing.

  As gas components contained in the fine bubbles, in addition to air, there are chlorine and ozone that have a bactericidal effect, carbonic acid and nitrogen that have a moisturizing effect, fragrant component gas with a fragrance, hydrogen that has an antioxidant effect, and a deodorizing effect. A specific effect gas having a specific effect, such as gas, can be used. It is also possible to mix finishing components such as a scent component and a moisturizing component with the generated nanobubble water. In addition, in the present invention, the fine bubbles are not always essential.

  The electrolyzed water producing unit 24 electrolyzes the electrolyzed water raw material liquid to produce electrolyzed water, and supplies the electrolyzed water storage unit 25. As the electrolyzed water generating unit 24, a known one can be used, and for example, a diaphragmless electrolytic cell can be used. Further, acidic and alkaline electrolyzed water produced in a two-tank type or three-tank type electrolytic cell may be mixed.

  A mixing / diluting unit (not shown) connected to a diluting water supply device for diluting electrolyzed water, such as tap water or pure water, is provided and is supplied from the electrolyzed water storage unit 25 at a preset mixing ratio. It is also possible to mix diluted water with electrolyzed water and supply it to the discharge part 26 as water for hand washing.

  In this way, the electrolyzed water supply device 2 is configured to supply the hand-washing water for a preset time in response to the user's request for supplying the hand-washing water.

  As shown in FIG. 4, the monitoring information transmitting device 3 has a computer configuration, and a control unit 31 including a CPU (Central Processing Unit), a ROM, and a RAM (not shown) comprehensively controls the entire monitoring information transmitting device 3. By controlling and expanding the program stored in the storage unit 33 into the RAM, various programs such as the hand-washing monitoring program are executed. As the monitoring information transmission device 3, for example, a small computer terminal such as a smartphone or a tablet terminal is preferably used.

  The monitoring information transmission device 3 has a so-called short-distance communication function having a communication range of several meters (for example, 0.5 to 3.0 m) such as sound waves or Bluetooth (registered trademark), and a wired LAN (Local Area Network) or wireless. It has two communication functions with a so-called local network that enables communication over a relatively long distance such as a LAN. The monitoring information transmitting device 3 also includes an operation input unit 34 including a touch panel and buttons, and a display unit 35 including liquid crystal.

  The control unit 31 uses short-distance communication and a local network to communicate with an external device via the external interface 32.

  As shown in FIG. 5, in the ID device 4, a control unit 41 including an MPU, a ROM, and a RAM (not shown) centrally controls the entire ID device 4. The control unit 41 uses a short-range communication function and communicates with an external device via the external interface 42. The ID device 4 uses a so-called replaceable dry battery such as a button battery or a rechargeable battery that can be repeatedly charged as a power source.

  The ID information is stored in the ID device 4, and the ID information is transmitted at a predetermined cycle (for example, 1 to 50 Hz) by near field communication. The ID device 4 has an acceleration sensor as the monitoring sensor 43. The monitoring sensor 43 measures acceleration at a predetermined cycle (for example, 1 to 1000 Hz). The stop determination unit 41A of the control unit 41 monitors the monitoring sensor 43 and determines whether or not the acceleration measurement value, which is the average value of accelerations in a predetermined measurement period (for example, 0.05 to 1.0 seconds), is greater than or equal to a movement threshold value. Determine.

  When the acceleration threshold is less than the movement threshold, the stop determination unit 41A determines that the current state is the non-moving state, and transmits the identifier information. On the other hand, when the acceleration measurement value is equal to or greater than the movement threshold value, it is determined that the movement state is present, and the transmission of the identifier information is stopped. That is, the ID device 4 transmits the identifier information when the worker is stopped, but does not transmit the identifier information when the worker is moving.

  The ID device 4 is attached to the worker by, for example, hanging it around the worker's neck with a strap or the like inside the work clothes, clipping it to a work hat or work clothes with a clip, or sewing it to the work clothes. (See FIG. 1).

In addition, the ID device 4 can change the transmission frequency of the identifier information according to the time of the non-moving state. For example, the ID device 4 counts the time during which the non-moving state is maintained, and when the non-moving time exceeds the first non-moving time threshold, decreases the transmission frequency of the identifier information.
Further, the ID device 4 stops the transmission of the identifier information when the non-moving time, which is the time during which the non-moving state is maintained, exceeds a second non-moving time threshold.

  Thus, for example, even when the worker leaves the ID device 4 after a break or after finishing work, the transmission of the identifier information can be automatically stopped, so that battery consumption can be suppressed.

  As shown in FIG. 6, in the supply information transmitting device 6, a control unit 61 including an MPU, a ROM and a RAM (not shown) controls the entire supply information transmitting device 6 as a whole. The control unit 61 uses the short-range communication function and communicates with an external device via the external interface 62. The supply information transmitting device 6 has an acceleration sensor as the monitoring sensor 63.

  The supply information transmission device 6 is attached to the electrolyzed water supply device 2. In particular, it is preferable to be attached to the vicinity of the discharge portion 26 (for example, the discharge hose portion) that vibrates greatly when the hand-washing water is supplied.

  The supply information transmission device 6 determines the presence or absence of supply of hand-washing water in the electrolytic water supply device 2 by measuring the vibration of the electrolytic water supply device 2. That is, the monitoring sensor 63 measures acceleration at a predetermined cycle (for example, 1 to 1000 Hz). The supply determination unit 61A of the supply information transmission device 6 monitors the monitoring sensor 63, and an acceleration measurement value, which is an average value of accelerations in a predetermined measurement period (for example, 0.05 to 1.0 seconds), is equal to or greater than a vibration threshold value or a predetermined value. It is determined whether or not it is within the range.

  When the acceleration measurement value is equal to or greater than the vibration threshold value or is within a predetermined range, the supply determination unit 61A transmits supply information indicating that hand washing water is supplied, while the acceleration measurement value is less than the vibration threshold value or within a predetermined range. If outside, supply information is not transmitted. That is, the supply information transmission device 6 transmits the supply information only when the electrolytic water supply device 2 is supplying the hand washing water, and does not transmit the supply information when the electrolytic water supply device 2 is not supplying the hand washing water.

  As described above, the monitoring information transmission device 3 receives the identifier information transmitted from the ID device 4 and the supply information transmitted from the supply information transmission device 6 by short-range communication having a communication range of several meters. Therefore, the monitoring information transmitting device 3 receives the identifier information and the supply information transmitted from the ID device 4 and the supply information transmitting device 6 within the communication range from the installed position.

  The ID detection unit 31A of the monitoring information transmission device 3 selects one piece of identifier information as an operator who performs hand washing (hereinafter referred to as a hand washing person) based on the radio field intensity of the received identifier information. For example, when the ID detection unit 31A receives the supply information, the ID detection unit 31A selects the identifier information having the highest radio field intensity as the handwasher when the supply information is received. As described above, the ID device 4 does not transmit the identifier information when the worker is moving. For this reason, it is possible to prevent an operator who happens to pass by nearby from recognizing it as a hand-washing person, and improve the recognition accuracy of the hand-washing person.

  Alternatively, the monitoring information transmitter 3 may supply a transmission request signal for the identifier information, and the ID device 4 may transmit the identifier information only when the transmission request signal is received. The transmission request signal at this time is supplied only in a predetermined communication range (for example, 0.5 to 2 m). As a result, the ID device 4 transmits the identifier information only when the worker is in the communication range of the monitoring information transmitting device 3 (that is, near the electrolytic water supply device 2). As a result, power consumption can be greatly reduced.

  The ID detection unit 31A causes the handwasher to identify himself / herself by displaying on the display unit 35 the face photograph and the name of the worker registered in the storage unit 33 in advance. Note that the face photograph of the worker can be taken and registered using the monitoring information transmission device 3. In addition, a facial photograph may be registered in the counting device 5.

  In addition, the monitoring information transmitting device 3 can also guide the operator to wash the hands by displaying an image on the display unit 35 or outputting sound by a sound output unit (not shown). For example, when the radio field intensity of the identifier information supplied from the worker's ID device 4 exceeds a predetermined radio field intensity, the monitoring information transmitting device 3 determines that the worker is ready for hand washing, For example, the display unit 35 displays a hand-washing promotion image that promotes hand-washing, which includes the words "Let's wash your hands" and images of hands.

  Further, the monitoring information transmitting device 3 can start displaying a hand-washing moving image that guides the hand-washing procedure at the same time as receiving the supply information. In this hand-washing moving image, according to the recommended hand-washing method, along with the lapse of hand-washing time, for example, after washing the rice for 5 seconds, wash between the fingers one by one, wash the wrist area for 2 seconds, etc. Manual washing procedures are displayed over time. Even if the still image is switched after a lapse of a predetermined time, the hand washing procedure can be displayed in the same manner.

  The monitoring information generation unit 31B confirms the reception time of the supply information, and when both the supply time of the hand-washing water and the reception time of the identifier information are equal to or higher than the hand-washing threshold value or within a predetermined range, the hand-washing person satisfies the supply condition. Recognizes that the hand washing has been carried out, the hand washing start time when the hand washing person starts hand washing (that is, reception of supply information), and the hand washing end time when the hand washing person finishes hand washing (that is, reception of supply information), The selected identifier and the handwashing monitoring information are transmitted to the tallying device 5. When the handwasher recognizes that the handwash has been stopped, the monitoring information generation unit 31B includes the handwash stop time when the handwash was stopped in the handwash monitor information.

  As shown in FIG. 7, the totalizing device 5 has a computer configuration, and a control unit 51 including a CPU (Central Processing Unit), ROM, and RAM (not shown) controls the totalizing device 5 as a whole. Has been done.

  Upon receiving the hand-washing monitoring information signal via the external interface 52, the control unit 51 of the tallying device 5 generates hand-washing monitoring information from the hand-washing monitoring information signal (transmission information) and performs the tallying process.

  Specifically, the control unit 51 collects hand-washing monitoring information based on the supply start signal and the supply end signal for each user associated with the identifier. As a result, the external interface 52 can total the time spent by each user for hand washing.

  Then, when the operator makes a display request for the counting result via the operation input unit 54, the control unit 51 collects the counting result in a graph or a list and causes the display unit 55 to display the result.

  As a result, the administrator can visually check the number of times of hand washing for each user and the time used for hand washing, and can thoroughly manage the hand washing.

  In addition to such a configuration, the hand-washing monitoring system 1 of the present embodiment is configured to capture an image of a hand-washing person's hand-washing.

  As shown in FIG. 8, in the camera device 7, a control unit 71 including an MPU, a ROM, and a RAM (not shown) controls the entire camera device 7 as a whole. The image capturing section 73 has an optical system in which optical components such as a lens and a light receiving element are combined. The control unit 71 controls the photographing unit 73 to photograph the state of hand washing by the hand-washing person and store the photographed state in the storage unit 74, and also supplies the photographed photographed image to the monitoring information transmitting apparatus 3 via the external interface 72. ..

  When the monitoring information transmission device 3 receives the supply information from the supply information transmission device 6 because the electrolyzed water supply device 2 is supplying the washing water, the monitoring information transmission device 3 sends a photographing start request signal indicating a request to start the photographing to the camera. Supply to the device 7. Upon receiving the shooting start request signal, the control unit 71 of the camera device 7 starts shooting of the shot image and supplies the shot image to the monitoring information transmitting device 3. The control unit 31 of the monitoring information transmitting device 3 supplies the captured image to the totaling device 5 as a part of the hand washing monitoring information. The aggregation device 5 stores the captured image in the storage unit 53 in association with the identifier information.

  Further, as shown in FIG. 9, the control unit 31 of the monitoring information transmission device 3 can display a captured image on the display unit 35 in addition to the above-mentioned hand-washing moving image. In FIG. 9, the hand-washing moving image is displayed on the entire surface, and the captured image is displayed as a reduced image that is less than 1/4 of the area of the display unit 35. As a result, the handwasher can be made aware that the image of the handwash is being taken, and the handwasher can be made aware of performing the appropriate handwash. The captured image and the instruction image may be displayed alternately, or only the captured image may be displayed.

  The tallying device 5 displays the captured image on the display unit 55 in response to a request from the administrator. Specifically, the control unit 51 of the tallying device 5 registers the received hand-washing monitoring information in the hand-washing monitoring database. In this hand-washing monitoring database, each hand-washing situation is registered in association with an identifier and time. Regarding the captured image, the file name and the recording location of the captured image are registered in the handwash monitoring database.

  In response to the operation input of the administrator on the operation input unit 54, the control unit 51 reproduces the captured image corresponding to the designated hand-washing monitoring information and displays it on the display unit 55. As a result, the hand-washing monitoring system 1 can manage the actual state of hand-washing by the hand-washing person. It is also possible to simultaneously reproduce the hand-washing instructional image when reproducing the captured image. This allows the administrator to easily check whether or not the handwasher is washing his / her hands as in the handwashing instruction image.

  Next, the hand washing monitoring information transmission process RT1 executed by the control unit 31 of the monitoring information transmitting device 3 according to the hand washing monitoring program will be described with reference to the flowchart of FIG.

  When the monitoring information transmitting device 3 starts the hand-washing monitoring information transmission process, the monitoring information transmitting device 3 proceeds to step S01.

  In step S01, the monitoring information transmitting device 3 determines whether or not the supply of hand-washing water has started based on the supply information. When a negative result is obtained, the monitoring information transmitter 3 waits for reception of supply information in step S01.

  When a positive result is obtained in step S01, the monitoring information transmitting device 3 at this time determines the time at this time as the supply start time, and proceeds to the next step S02.

  In step S02, the monitoring information transmitting device 3 confirms the radio field intensity of the identifier information being received, and when the identifier information having the highest radio field intensity is selected, the process proceeds to the next step S03.

  In step S03, the monitoring information transmission device 3 determines whether or not the supply of hand washing water is stopped based on the supply information. If a negative result is obtained here, the monitoring information transmitter 3 remains in step S03 and continues to receive supply information.

  On the other hand, when a positive result is obtained in step S03, the monitoring information transmitter 3 determines the time when the supply information signal was last received as the supply end time, and proceeds to the next step S04.

  In step S04, the monitoring information transmitter 3 determines whether the supply condition is satisfied based on the supply information and the received identifier information. If a negative result is obtained here, the monitoring information transmitting device 3 recognizes that hand washing is not performed, and returns to step S01. On the other hand, when a positive result is obtained in step S04, this means that the hand washing is properly performed by the hand washing person, and at this time, the monitoring information transmitting device 3 moves to the next step S05.

  In step S05, the monitoring information transmitting device 3 transmits the supply start time, the supply end time, and the identifier extracted from the identifier information as the hand wash monitoring information, and then moves to the end step and ends the process.

<Second Embodiment>
Next, a second embodiment will be described with reference to FIG. The hand-washing monitoring system 101 of the second embodiment differs from that of the first embodiment described above in that the worker is not identified, and that it is not linked with the supply information. In the second embodiment, the reference numerals obtained by adding 100 to the portions corresponding to those in the first embodiment are attached, and the description of the same portions will be omitted.

  As shown in FIG. 11, the hand-washing monitoring system 101 has a faucet 102 as a hand-washing water supply means, a camera device 107, and a totaling device 105.

  The faucet 102 is connected to a water pipe, and manually operates a faucet lever (not shown) to supply tap water as water for hand washing.

  The camera device 107 is connected to the totaling device 105 by wireless or wired communication. The camera device 107 transmits the photographed image photographed by the photographing unit 173 to the aggregation device 105 via the external interface 172.

  The control unit 151 of the totaling device 105 captures the received captured image at the capturing time (for example, the capturing time supplied from the camera device 107 or the reception time when the capturing device 105 receives the captured image, and the capturing estimated based on the receiving time). It is stored in the storage unit 174 in association with the time). Further, the control unit 151 analyzes the photographed image, detects a photographed image (hereinafter, referred to as a selected handwash image) including a state of handwashing by the handwasher, and associates the extracted selected handwash image with the photographing time. And stores it in the storage unit 174.

  For example, the control unit 151 of the tallying device 105 detects the size of the motion vector between the captured images and the presence or absence of hand washing in the captured images by detecting the skin color. Since the motion vector theoretically becomes zero when there is no handwasher in the captured image, it is possible to determine the presence or absence of a handwasher based on the magnitude of the average value or the maximum value of the motion vector, for example. In addition, it is possible to determine the presence or absence of a hand-washer based on the ratio of the skin color (skin color to brown) in the captured image. The presence or absence of a handwasher is totally determined, such as determining that there is a handwasher when two or more criteria are set and one or more criteria satisfy the condition, or the sum of multiple criteria satisfies the condition. You may.

  In response to the operation of the operation input unit 154 by the administrator, a list of shooting times is displayed as a record of hand washing. When the administrator selects the shooting time, the corresponding selected handwash image is reproduced and displayed on the display unit 155.

  On the other hand, for the received captured image, the control unit 151 can reduce the data required to store the captured image by reducing the resolution or deleting the captured image after a predetermined storage time has elapsed from the capturing time.

  As described above, in the second embodiment, the selected hand-washing image is selected and stored from the images captured by the camera device 107. Further, the selected hand-washed image is copied and re-stored, and the original photographed image is subjected to a process of reducing the storage capacity after a lapse of a predetermined time.

<Operation and effect>
The features of the invention group extracted from the above-described embodiments will be described below, showing problems and effects as necessary. It should be noted that, in the following, for ease of understanding, the corresponding configurations in the above-described embodiments are appropriately shown in parentheses or the like, but the present invention is not limited to the specific configurations shown in brackets or the like. The meanings and examples of the terms described in each feature may be applied as the meanings and examples of the terms described in other features described in the same wording.

  In the hand-washing monitoring system (hand-washing monitoring system 1) of the present invention, the hand-washing water supply means (the draining portion 26, the faucet 102) for supplying the hand-washing water and the photographing means (camera device 7) for photographing the hand-washing by the worker with the hand-washing water , 107), a transmission means (external interfaces 72, 172) for transmitting the photographed hand-washing photographed image, and a storage means (collection means for receiving and storing the hand-washing photographed image, which is arranged apart from the photographing means). Device 5, 105) and display means (display unit 55) for displaying the hand-washed photographed image.

  As a result, in the hand-washing monitoring system, the hand-washing situation can be photographed and stored, so that the administrator can manage the actual hand-washing situation.

  In the hand-washing monitoring system, the image capturing means performs image capturing regardless of the presence or absence of an operator and transmits the hand-washed captured image to the storage means, and the storage means causes the worker to wash the hand-washed image from the hand-washed captured image. An image is selected as a selected hand-washing image, and is stored in association with a shooting time that represents the time when the selected hand-washing image was shot.

  As a result, in the hand-washing monitoring system, the selected hand-washed photographed image can be selected on the side of the storage means, so that the hand-washing can be monitored using a general camera device.

  In the hand-washing monitoring system, the storage means performs a capacity reduction process for reducing the storage capacity of the hand-washed captured image other than the selected hand-washed image.

  As a result, the hand-washing monitoring system can reduce the storage capacity for the hand-washed photographed image, and the hand-washing monitoring system can be used without stress even when the hand-washing frequency is low.

  In the hand-washing monitoring system, the storage unit reduces the storage capacity of the hand-washed captured images other than the selected shot image as the capacity reduction process, and deletes the hand-washed shot image other than the selected shot image after the deletion time elapses. It is characterized by doing.

  As a result, in the hand-washing monitoring system, the hand-washing images other than the selected hand-washing image can be left for a certain period while saving the storage capacity, and the administrator can check the overall situation.

  In the hand-washing monitoring system, the photographing means may photograph the hand-washed photographed image according to an operator or presence / absence of hand-washing, and send it to the storage means.

  As a result, in the hand-washing monitoring system, shooting can be performed only in the situation where hand-washing has been performed, so that it is possible to reduce the storage capacity of electricity, communication, and storage means for shooting.

  The hand washing monitoring system includes an ID (Identification) unit that is carried by an operator and transmits an identifier as identifier information by wireless communication, and the photographing unit photographs the hand washing photographed image according to the acquisition of the identifier information. And transmitting to the storage means.

  As a result, in the hand-washing monitoring system, since the hand-washing person and the photographed image are associated with each other, it is possible to specify who is the photographed image having his hands washed.
