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

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 transmitting devices 3A to 3B and supply information transmitting devices 6A to 6B are installed for 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 ID devices as there are workers.

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

A waiting line 11 for waiting for their turn to wash their hands is drawn on the floor near the hand-washing area 9, and workers wait outside the waiting line 11 when viewed from the hand-washing area 9. Therefore, in the hand-washing area 10, there are only workers who are washing their hands, workers who are moving to the hand-washing area 9 to wash their hands, and workers who are moving to leave the hand-washing area 10 after washing their hands. will exist.

As shown in FIG. 3, in the electrolyzed water supply device 2, a control section 21 including an MPU (Micro Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown) controls the electrolyzed water supply device 2. The entire system is controlled in an integrated manner.

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

Upon receiving the hand washing request signal from the sensor 22, the control section 21 starts discharging the hand washing water from the electrolyzed water storage section 25.

Specifically, the control unit 21 supplies a discharge start signal to the electrolyzed water storage unit 25 to cause the discharge unit 26 to discharge electrolyzed water for hand washing (hereinafter referred to as hand washing water). Furthermore, after supplying hand washing water for a preset supply time, the control unit 21 supplies a supply stop signal to the electrolyzed water storage unit 25 . Thereby, the electrolyzed water supply device 2 supplies water for hand washing only for a preset supply time.

Further, the control unit 21 monitors the remaining amount of water for hand washing in the electrolyzed water storage unit 25, and supplies a generation request signal to the electrolyzed water generating unit 24 to generate electrolyzed water, for example, when the amount of water for washing hands becomes less than a predetermined amount. do.

The raw material liquid storage section 23 is connected to the electrolyzed water generation section 24 . The raw material liquid storage section 23 stores the electrolyzed water raw material liquid and supplies the electrolyzed water raw material liquid to the electrolyzed water generation section 24 . By using the adjusted electrolyzed water raw material solution instead of tap water as the raw solution of electrolyzed water, calcification of electrodes and piping can be prevented without installing a filter, and the electrolyzed water supply device 2 can be downsized.

As this electrolyzed water raw material solution, in order to generate hypochlorous acid, it is preferable to use one containing chlorine as part or all of the electrolyte. Preferably, an aqueous solution of a mixture of sodium chloride and hydrochloric acid, an aqueous sodium chloride solution, hydrochloric acid, potassium chloride, etc. are used alone or in combination. This is to maintain 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 solution, it is preferable to use, for example, an aqueous solution containing sodium such as sodium bicarbonate, sodium carbonate, or sodium hydroxide, or an aqueous solution containing potassium such as potassium carbonate or potassium hydroxide. Of course, it is also possible to use a mixture of acidic electrolyzed water and alkaline electrolyzed water.

Furthermore, the electrolyzed water raw material liquid in this embodiment may contain fine bubbles of a regulating gas that has a regulating function of increasing the amount of hypochlorous acid present. For example, by using oxygen gas (O ₂ ) or ozone gas (O ₃ ) as the adjustment gas, oxidation of chlorine can be promoted, and as a result, the amount of hypochlorous acid present in electrolyzed water can be increased. .

Furthermore, by using chlorine gas (Cl ₂ ) as a regulating gas, the chlorine content in the electrolyzed water raw material solution can be increased, and as a result, the amount of hypochlorous acid present in the electrolyzed water can be increased. . Furthermore, by using hydrogen gas (H ₂ ) as the adjusting gas, the pH of the electrolyzed water can be easily controlled within the range of 2.7 to 6.5.

The microbubbles are so-called microbubbles with a size of less than 1 μm, and can stably exist in the electrolyzed water raw material solution for several months or more. In addition, instead of electrolyzed water, nanobubble water containing microbubbles, water with sterilizing, aromatic, and moisturizing effects, tap water, etc. can be used as water for hand washing.

In addition to air, the gas components contained in microbubbles include chlorine and ozone, which have a bactericidal effect, carbonic acid and nitrogen, which have a moisturizing effect, fragrant component gas, hydrogen, which has an antioxidant effect, and deodorizing effect. Special effect gases, such as gases, can be used that have a particular effect. Furthermore, finishing components such as fragrance components and moisturizing components can also be mixed with the generated nanobubble water. Note that in the present invention, microbubbles are not necessarily essential.

The electrolyzed water generation section 24 electrolyzes the electrolyzed water raw material solution to produce electrolyzed water, and supplies it to the electrolyzed water storage section 25 . As the electrolyzed water generating section 24, a known one can be used, and for example, a diaphragmless electrolytic cell can be used. Furthermore, acidic and alkaline electrolyzed water produced in two-tank or three-tank electrolytic cells may be mixed.

Note that a mixing dilution unit (not shown) connected to a dilution water supply device for diluting electrolyzed water, such as tap water or pure water, is provided, and the electrolyzed water is supplied from the electrolyzed water storage unit 25 at a preset mixing ratio. Dilution water may be mixed with electrolyzed water and supplied to the discharge section 26 as water for hand washing.

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

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

The monitoring information transmitting device 3 has a so-called short-range communication function, such as sound waves or Bluetooth (registered trademark), which has a communication range of several meters (for example, 0.5 to 3.0 meters), and a wired LAN (Local Area Network) or wireless communication function. It has two communication functions with a so-called local network, such as LAN, which allows communication over relatively long distances. Further, the monitoring information transmitting device 3 includes an operation input section 34 consisting of a touch panel or buttons, and a display section 35 consisting of a liquid crystal or the like.

The control unit 31 communicates with an external device via the external interface 32 using short-range communication and a local network.

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

The ID device 4 stores identifier information, and transmits the identifier information at a predetermined frequency (for example, 1 to 50 Hz) by short-range communication. The ID device 4 has an acceleration sensor as a monitoring sensor 43. The monitoring sensor 43 measures acceleration at a predetermined frequency (for example, 1 to 1000 Hz). The stop determination unit 41A of the control unit 41 monitors the monitoring sensor 43 and determines whether the acceleration measurement value, which is the average value of acceleration during a predetermined measurement period (for example, 0.05 to 1.0 seconds), is greater than or equal to the movement threshold. Discern.

If the acceleration threshold is less than the movement threshold, the stop determination unit 41A determines that the vehicle is currently in a non-moving state, and transmits the identifier information. On the other hand, if the acceleration measurement value is equal to or greater than the movement threshold, it is determined that the current state is movement, 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, being hung around the worker's neck with a strap inside the work clothes, clipped to a work hat or work clothes, or sewn into the work clothes. (see Figure 1).

Further, the ID device 4 can change the frequency of transmitting the identifier information depending on the time of non-moving state. For example, the ID device 4 counts the time during which it maintains a non-moving state, and when the non-moving time exceeds a first non-moving time threshold, it reduces the frequency of transmission of the identifier information.
Furthermore, when the non-movement time, which is the time during which the ID device 4 maintains the non-movement state, exceeds a second non-movement time threshold, the ID device 4 stops transmitting the identifier information.

As a result, even if the worker leaves the ID device 4 unattended during a break or after work, 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, ROM, and RAM (not shown) controls the entire supply information transmitting device 6 in an integrated manner. The control unit 61 uses a short-range communication function to communicate with an external device via the external interface 62. The supply information transmitting device 6 includes an acceleration sensor as a monitoring sensor 63.

The supply information transmitting device 6 is attached to the electrolyzed water supply device 2. In particular, it is preferable to attach it to the vicinity of the discharge part 26 (for example, the discharge hose part) which vibrates greatly when water for washing hands is supplied.

The supply information transmitting device 6 determines whether water for hand washing is being supplied in the electrolyzed water supply device 2 by measuring vibrations of the electrolyzed water supply device 2 . That is, the monitoring sensor 63 measures acceleration at a predetermined frequency (for example, 1 to 1000 Hz). The supply determination unit 61A of the supply information transmitting device 6 monitors the monitoring sensor 63, and determines whether the acceleration measurement value, which is the average value of acceleration during a predetermined measurement period (for example, 0.05 to 1.0 seconds), is equal to or higher than the vibration threshold value or a predetermined value. Determine whether it is within the range of .

The supply determination unit 61A transmits supply information indicating that water for washing hands is being supplied when the measured acceleration value is equal to or higher than the vibration threshold or within a predetermined range, and when the measured acceleration value is less than the vibration threshold or within a predetermined range. If not, supply information is not sent. That is, the supply information transmitting device 6 transmits supply information only when the electrolyzed water supply device 2 is supplying water for hand washing, and does not transmit the supply information when the electrolyzed water supply device 2 is not supplying water for hand washing.

As described above, the monitoring information transmitting device 3 receives the identifier information transmitted from the ID device 4 and the supply information transmitted from the supply information transmitting device 6 through 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 that are within the communication range from the installed position.

The ID detection unit 31A of the monitoring information transmitting device 3 selects one piece of identifier information as a worker who washes hands (hereinafter referred to as a hand-washer) based on the radio wave intensity of the received identifier information. For example, when the ID detection unit 31A receives the supply information, it selects the identifier information with the highest radio wave intensity at the time of reception as the hand washing person. As mentioned above, the ID device 4 does not transmit identifier information when the worker is moving. Therefore, it is possible to prevent a worker who happens to be passing by from being recognized as the person washing hands, and it is possible to improve the accuracy of recognition of the person washing hands.

It is also possible for the monitoring information transmitting device 3 to supply a transmission request signal for identifier information, and for the ID device 4 to transmit the identifier information only when the transmission request signal is received. The transmission request signal at this time is supplied only within 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 within the communication range of the monitoring information transmitting device 3 (that is, in the vicinity of the electrolyzed water supply device 2), compared to a case where the identifier information is constantly transmitted. As a result, power consumption can be significantly reduced.

The ID detection unit 31A displays the face photo and name of the worker registered in the storage unit 33 in advance on the display unit 35, thereby allowing the person washing the hands to identify himself/herself. Note that a photograph of the worker's face can be taken and registered using the monitoring information transmitting device 3. Further, a facial photograph may be registered in the totaling device 5.

The monitoring information transmitting device 3 can also instruct the worker to wash their hands by displaying an image on the display unit 35 or outputting sound from a sound output unit (not shown). For example, if 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 to wash his hands, For example, a hand-washing promotion image that promotes hand-washing, which includes the phrase "Let's wash your hands" and an image of a hand, is displayed on the display unit 35.

Further, the monitoring information transmitting device 3 can start displaying a hand washing moving image that provides instructions on hand washing procedures at the same time as receiving the supply information. In this handwashing video, we follow the recommended handwashing method, and as the handwashing time progresses, we show specific instructions, such as washing between the fingers one by one after massaging the hands for 5 seconds, and washing the area around the wrists for 2 seconds. Steps for washing your hands are displayed over time. Note that hand-washing procedures can be similarly displayed even if the still images are switched after a predetermined period of time has elapsed.

The monitoring information generation unit 31B checks the reception time of the supply information, and if the supply time of handwashing water and the reception time of the identifier information are both above the handwashing threshold or within a predetermined range, the supply condition is met and the handwasher is A hand-washing start time when the hand-washer recognized that he had washed his hands and started hand-washing (that is, when he started receiving the supply information), and a hand-washing end time when the hand-washer finished hand-washing (that is, when he finished receiving the supply information); The selected identifier is transmitted to the aggregation device 5 as hand washing monitoring information. In addition, when the monitoring information generation unit 31B recognizes that the person washing hands has stopped washing their hands, the monitoring information generation unit 31B includes the hand washing stop time at which the person washing their hands stopped washing their hands in the hand washing monitoring information.

As shown in FIG. 7, the aggregation device 5 has a computer configuration, and a control section 51 consisting of a CPU (Central Processing Unit), ROM, and RAM (not shown) centrally controls the entire aggregation device 5. being done.

When the control unit 51 of the aggregation device 5 receives the handwashing monitoring information signal via the external interface 52, it generates handwashing monitoring information from the handwashing monitoring information signal (transmission information) and performs aggregation processing.

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

Then, when the operator issues a display request for the tally results via the operation input section 54, the control section 51 summarizes the tally results in a graph or a list and causes the display section 55 to display the tally results.

As a result, the administrator can visually check the number of times each user washes their hands and the time spent washing their hands, and can thoroughly manage hand washing.

In addition to this configuration, the handwashing monitoring system 1 of this embodiment is configured to photograph the handwashing process of the person washing the hands.

As shown in FIG. 8, the camera device 7 is configured such that a control section 71 including an MPU, ROM, and RAM (not shown) controls the entire camera device 7 in an integrated manner. The photographing unit 73 has an optical system that is a combination of optical components such as lenses, a light receiving element, and the like. The control unit 71 controls the photographing unit 73 to photograph the handwashing process of the handwasher and stores it in the storage unit 74, and also supplies the photographed image to the monitoring information transmitting device 3 via the external interface 72. .

When the monitoring information transmitting device 3 receives supply information from the supply information transmitting device 6 due to the electrolyzed water supply device 2 supplying water for hand washing, the monitoring information transmitting device 3 transmits a photographing start request signal representing a request to start photographing to the camera. Supplied to device 7. Upon receiving the photographing start request signal, the control unit 71 of the camera device 7 starts photographing a photographed image and supplies the photographed image to the monitoring information transmitting device 3 . The control unit 31 of the monitoring information transmitting device 3 supplies the photographed image to the aggregation device 5 as part of the hand washing monitoring information. The aggregation device 5 stores photographed images in the storage unit 53 in association with identifier information.

Furthermore, as shown in FIG. 9, the control unit 31 of the monitoring information transmitting device 3 can display a photographed 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 photographed image is displayed as a reduced image that is less than 1/4 of the area of the display section 35. Thereby, the person washing the hands can be made aware that the person washing the hands is being photographed, and the person washing the hands can be made conscious of washing the hands appropriately. Note that the photographed image and the guide image may be displayed alternately, or only the photographed image may be displayed.

The aggregation device 5 displays the photographed images on the display section 55 in response to a request from the administrator. Specifically, the control unit 51 of the aggregation device 5 registers the received hand washing monitoring information in the hand washing monitoring database. In this handwashing monitoring database, each handwashing situation is registered in association with an identifier and time. For photographed images, the file name and recording location of the photographed images are registered in the handwashing monitoring database.

In response to the administrator's operational input to the operational input unit 54, the control unit 51 reproduces the photographed image corresponding to the designated hand washing monitoring information and displays it on the display unit 55. Thereby, the handwashing monitoring system 1 can manage the actual state of handwashing by the handwasher. Note that when playing back the photographed image, it is also possible to play back the handwashing instruction image at the same time. This allows the administrator to easily check whether the person washing their hands is washing their hands in accordance with the hand washing instruction image.

Next, hand washing monitoring information transmission processing RT1 executed by the control unit 31 of the monitoring information transmitting device 3 according to the hand washing monitoring program will be described using the flowchart of FIG. 10.

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

In step S01, the monitoring information transmitting device 3 determines whether or not hand washing water supply has started based on the supply information. If a negative result is obtained, the monitoring information transmitting device 3 waits to receive supply information in step S01.

If a positive result is obtained in step S01, then the monitoring information transmitting device 3 determines the current time as the supply start time, and moves to the next step S02.

In step S02, the monitoring information transmitting device 3 checks the radio field strength of the identifier information being received, selects the identifier information with the highest radio field strength, and then moves to the next step S03.

In step S03, the monitoring information transmitting device 3 determines whether the supply of water for washing hands has been stopped based on the supply information. If a negative result is obtained here, the monitoring information transmitting device 3 stays at step S03 and continues receiving supply information.

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

In step S04, the monitoring information transmitting device 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 being performed, and returns to step S01. On the other hand, if a positive result is obtained in step S04, this indicates that the person washing the hands properly washed the hands, and in this case, 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 hand washing monitoring information, and then moves to an end step and ends the process.

<Second embodiment>
Next, a second embodiment will be described using FIG. 11. The hand washing monitoring system 101 according to the second embodiment differs from the first embodiment in that it does not identify the worker and does not link with supply information. In the second embodiment, parts corresponding to those in the first embodiment are given numerals incremented by 100, and descriptions of the same parts are omitted.

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

The faucet 102 is connected to a water pipe, and supplies tap water for hand washing by manually operating a faucet lever (not shown).

Camera device 107 is connected to tabulation device 105 via 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 aggregation device 105 updates the received captured image with the captured time (for example, the captured time supplied from the camera device 107 or the reception time when the aggregation device 105 received the captured image, or the captured image estimated based on the received time). time, etc.) and stored in the storage unit 174. Furthermore, the control unit 151 analyzes the photographed images, detects a photographed image that includes the handwashing situation of the person washing the hands (hereinafter referred to as a selected hand-washing image), and associates the extracted selected hand-washing image with the photographing time. and stored in the storage unit 174.

For example, the control unit 151 of the aggregation device 105 detects the presence or absence of hand washing in the captured images based on the magnitude of the motion vector between the captured images, skin color detection, and the like. If there is no person washing hands in the captured image, the motion vector is theoretically zero, so it is possible to determine whether there is a person washing hands, for example, based on the magnitude of the average value or maximum value of the motion vector. Furthermore, it is possible to determine whether someone is washing their hands or not based on the ratio of skin color (skin color to brown) in the photographed image. The presence or absence of a person washing their hands can be determined in total, such as by setting two or more discrimination criteria and determining that there is a person washing their hands when one or more of the criteria satisfies the condition or when the sum of multiple criteria satisfies the condition. You may do so.

In response to the administrator's operation on the operation input unit 154, the photographing time is displayed in a list as a record of hand washing. When the administrator selects a photographing time, the corresponding selected hand washing image is played back and displayed on the display section 155.

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

In this way, in the second embodiment, the selected hand washing image is selected from the images taken by the camera device 107 and stored. Further, the selected hand washing image is copied and re-stored, and the original photographed image undergoes processing to reduce the storage capacity after a predetermined period of time has elapsed.

<Operations and effects>
Hereinafter, the features of the invention group extracted from the above-described embodiments will be explained, indicating problems, effects, etc. as necessary. In the following, for ease of understanding, structures corresponding to each of the above embodiments are indicated in parentheses as appropriate, but the present invention is not limited to the specific structures shown in parentheses. Further, the meanings and examples of terms described in each feature may be applied as the meanings and examples of terms described in other features described in the same wording.

The hand-washing monitoring system (hand-washing monitoring system 1) of the present invention includes a hand-washing water supply means (discharge unit 26, faucet 102) that supplies water for hand-washing, and a photographing means (camera device 7) that photographs a worker washing his or her hands with the hand-washing water. , 107), a transmitting means (external interface 72, 172) for transmitting the photographed hand-washing images, and a storage means (aggregation) disposed apart from the photographing means for receiving and storing the hand-washing photographed images. device 5, 105) and display means (display unit 55) for displaying the hand washing photographed image.

With this, the handwashing monitoring system can photograph and store the handwashing situation, allowing the administrator to manage the actual handwashing situation.

In the hand washing monitoring system, the photographing means takes pictures regardless of the presence or absence of a worker and transmits the hand washing photographed image to the storage means, and the storage means detects that the worker is washing hands from the hand washing photographed image. The present invention is characterized in that an image is selected as a selected hand-washing image and stored in association with a photographing time representing the time at which the selected hand-washing image was photographed.

Thereby, in the hand washing monitoring system, since the selected hand washing photographed image can be selected on the storage means side, hand washing can be monitored using a general camera device.

In the handwashing monitoring system, the storage means executes a capacity reduction process to reduce the storage capacity of the handwashing photographed images other than the selected handwashing image.

As a result, in the hand washing monitoring system, the storage capacity for hand washing photographed images can be reduced, and even if hand washing is infrequent, the hand washing monitoring system can be used without stress.

In the handwashing monitoring system, the storage means reduces the storage capacity of the handwashing images other than the selected image as the capacity reduction process, and deletes the handwashing image other than the selected image after a deletion time has elapsed. It is characterized by

As a result, in the hand washing monitoring system, hand washing images other than the selected hand washing images can be retained for a certain period of time while saving memory capacity, and the administrator can check the overall situation.

In the handwashing monitoring system, the photographing means photographs the handwashing image according to the worker or whether the handwashing is being done or not, and transmits the photographed image to the storage means.

As a result, the handwashing monitoring system can take pictures only when handwashing is being performed, so it is possible to reduce the electricity, communication, and storage capacity of the storage means for taking pictures.

The handwashing monitoring system includes an ID (Identification) means carried by a worker and transmitting an identifier as identifier information by wireless communication, and the photographing means photographs the handwashing photographed image in response to acquiring the identifier information. , and is characterized in that the information is transmitted to the storage means.

As a result, in the hand washing monitoring system, the person washing hands and the photographed image can be associated with each other, so that it is possible to specify who is washing hands in the photographed image.

The hand-washing monitoring system includes a supply detecting means for detecting whether or not hand-washing water is being supplied by the hand-washing water supply means and transmitting the supply information, and the photographing means receives the supply information and acquires the supply information. The hand washing photographic image is photographed in accordance with the above, and is transmitted to the storage means.

As a result, the handwashing monitoring system can take pictures of handwashing in accordance with the supply of handwashing water, so it can take pictures at appropriate timing.

In the hand-washing monitoring system, the supply detection means detects whether or not the hand-washing water is being supplied by detecting vibrations in the hand-washing water supply means.

Thereby, in the hand washing monitoring system, the presence or absence of the supply of hand washing water can be detected using the external supply detection means, so that the configuration of the monitoring system can be simplified.

In the hand-washing monitoring system, the supply detection means detects whether or not the hand-washing water is being supplied by receiving a supply signal representing the hand-washing water supply status from the hand-washing water supply means.

Thereby, the hand washing monitoring system can reliably detect the presence or absence of hand washing water supply and take pictures at appropriate timing.

The handwashing monitoring system is characterized by comprising a photographing display section that is provided at a position where a worker can view the handwashing while washing his hands and displays the handwashing photographed image photographed by the photographing means.

As a result, the hand washing monitoring system can make the worker aware that a photograph is being taken and apply psychological pressure to the worker, thereby making the worker aware of proper hand washing.

This allows the handwashing monitoring system to save on electricity costs and communication capacity.

It is possible to combine the first and second embodiments described above as appropriate. For example, a captured image taken by a camera device may be supplied to the monitoring information transmitting device, the monitoring information transmitting device may extract the selected hand washing image, and transmit the selected hand washing image to the aggregation device.

In the second embodiment described above, the selected hand washing images are extracted from the photographed images sent to the aggregation device 105 and stored in duplicate, while the capacity reduction process is executed for the photographed images. The present invention is not limited to this. For example, the selected hand-washing image may not be duplicated and stored, and capacity reduction processing may be performed on portions other than the selected hand-washing image. For example, at the same time as the selected hand-washing image is extracted, the resolution of the portion of the photographed image other than the selected hand-washing image is lowered, and after a predetermined deletion time has elapsed, the portion other than the selected hand-washing image is deleted. Capacity reduction processing may also be executed. In this case, the storage means may store at least the start time and end time of the selected hand-washing image as the photographing time without modifying the hand-washing photographed image. Further, capacity reduction processing is not essential.
