<Basic configuration of hand washing monitoring system>
Next, a mode 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 has an electrolyzed water supply device 2 , a monitoring information transmission device 3 , an ID (Identification) device 4 , a counting device 5 and a supply information transmission device 6 . In FIG. 1, monitoring information transmitting devices 3A-3B and supply information transmitting devices 6A-6B are installed for two electrolyzed water supply devices 2A-2B, respectively. 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 in a factory that handles food, for example. FIG. 2 represents one workroom in a factory. The electrolyzed water supply device 2 and the monitoring information transmission device 3 are arranged in the vicinity of the wash basin 9 in the factory and supply water for washing hands to the wash basin 9 .

A waiting line 11 waiting for the turn of hand washing is drawn on the floor in the vicinity of the wash basin 9, and workers wait outside the waiting line 11 as seen from the wash basin 9. - 特許庁Therefore, in the hand-washing area 10, there are only the workers who are washing their hands, the workers who are moving to the washing area 9 to wash their hands, and the workers who are moving out of the washing area 10 after finishing their hand-washing. will exist.

As shown in FIG. 3, the electrolyzed water supply device 2 has a control unit 21 composed of an MPU (Micro Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown). It is made to control the whole in an integrated manner.

The sensor 22 is preferably of a non-contact type, eg infrared, for hygienic reasons. For example, the sensor 22 supplies a hand-washing request signal to the control unit 21 when the user's hand-washing request is sensed by the user holding his or her hand in front of the sensor 22 .

Upon receiving the hand-washing request signal from sensor 22 , control unit 21 starts discharging hand-washing water from electrolyzed water reservoir 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). Further, the control unit 21 supplies a supply stop signal to the electrolyzed water storage unit 25 after supplying hand washing water for a preset supply time. As a result, the electrolyzed water supply device 2 supplies hand washing water for a preset supply time.

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

The raw material liquid reservoir 23 is connected to the electrolyzed water generator 24 . The raw material liquid reservoir 23 stores the raw material liquid for electrolyzed water and supplies the raw material liquid for electrolyzed water to the electrolyzed water generating section 24 . By using the adjusted electrolyzed water raw material solution instead of tap water as the electrolyzed water stock solution, calcification of the electrodes and pipes can be prevented without installing a filter, and the size of the electrolyzed water supply device 2 can be reduced.

As the electrolyzed water raw material liquid, one containing chlorine as part or all of the electrolyte is preferably used 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, etc. are used alone or in combination. This is to keep the pH at which the content of hypochlorous acid is stabilized.

Alkaline electrolyzed water can also be used as hand-washing water. In this case, it is preferable to use, 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 as the electrolyzed water raw material solution. 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 the present embodiment may contain fine bubbles of the adjustment gas having the adjustment function of increasing the abundance of hypochlorous acid. For example, by using oxygen gas (O ₂ ) or ozone gas (O ₃ ) as the adjustment gas, the oxidation of chlorine can be promoted, and as a result, the abundance of hypochlorous acid in the electrolyzed water can be increased. .

In addition, by using chlorine gas (Cl ₂ ) as the adjustment gas, the chlorine content in the electrolyzed water raw material solution can be increased, and as a result, the abundance of hypochlorous acid in the electrolyzed water can be increased. . Further, 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.

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

In addition to air, the gas components contained in the microbubbles include chlorine and ozone, which have a sterilizing effect, carbonic acid and nitrogen, which have a moisturizing effect, fragrant gas, hydrogen, which has an antioxidant effect, and deodorizing gas. Special effect gases, such as gases, with specific effects can be used. In addition, finishing ingredients such as fragrance ingredients and moisturizing ingredients can be mixed with the generated nanobubble water. In addition, in this invention, a fine bubble is not necessarily essential.

The electrolyzed water generating unit 24 electrolyzes the electrolyzed water raw material liquid to produce electrolyzed water, and supplies the electrolyzed water storage unit 25 with the electrolyzed water. As the electrolyzed water generator 24, a known one can be used, and for example, a non-diaphragm type electrolytic cell can be used. Acidic and alkaline electrolyzed water generated in two-tank and three-tank electrolytic cells may also be mixed.

A mixing and 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 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 part 26 as hand-washing water.

In this manner, the electrolyzed water supply device 2 supplies handwashing water for a preset time according to the user's handwashing water supply request.

As shown in FIG. 4, the monitoring information transmitting device 3 is composed of a computer. 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 transmission device 3, for example, a small computer terminal such as a smart phone or a tablet terminal is preferably used.

The monitoring information transmitting device 3 has a so-called short-range communication function with a communication range of several meters (for example, 0.5 to 3.0 m) such as sound wave or Bluetooth (registered trademark), 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 enables communication over a relatively long distance. The monitoring information transmitting device 3 also has an operation input section 34 made up of a touch panel and buttons, and a display section 35 made up 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 controller 41 comprising an MPU, a ROM and a RAM (not shown) controls the ID device 4 as a whole. The control unit 41 communicates with an external device via the external interface 42 using the short-range communication function. 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 supply.

Identifier information is stored in the ID device 4, and the identifier information is transmitted at a predetermined cycle (for example, 1 to 50 Hz) by short-range communication. The ID device 4 has an acceleration sensor as the monitoring sensor 43 . The monitoring sensor 43 measures acceleration at a predetermined cycle (1 to 1000 Hz, for example). The stop determination unit 41A of the control unit 41 monitors the monitoring sensor 43 and determines whether or not the measured acceleration 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. discriminate.

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, if the measured acceleration value is greater than or equal to the moving threshold, it is determined that the current state is moving, and transmission of the identifier information is stopped. That is, the ID device 4 transmits identifier information when the worker is stopped, but does not transmit identifier information when the worker is moving.

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

Further, the ID device 4 can change the transmission frequency of the identifier information according to the non-moving time. For example, the ID device 4 counts the time during which the non-moving state is maintained, and reduces the frequency of transmitting the identifier information when the non-moving time exceeds a first non-moving time threshold.
When the non-moving time, which is the time during which the non-moving state is maintained, exceeds the second non-moving 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 break time or after the end of work, the transmission of the identifier information can be automatically stopped, so battery consumption can be suppressed.

As shown in FIG. 6, the supply information transmission device 6 is configured such that a control section 61 composed of an MPU, a ROM and a RAM (not shown) controls the entire supply information transmission device 6 in an integrated manner. The control unit 61 communicates with an external device via the external interface 62 using the short-range communication function. The supply information transmission 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 preferably attached to the vicinity of the discharge portion 26 (for example, the discharge hose portion) that vibrates greatly when hand-washing water is supplied.

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

When the measured acceleration value is equal to or greater than the vibration threshold value or within a predetermined range, the supply determination unit 61A transmits supply information indicating that hand washing water is being supplied, while the measured acceleration value is less than the vibration threshold value or within a predetermined range. Otherwise, do not send feed information. That is, the supply information transmitting device 6 transmits the supply information only when the electrolyzed water supply device 2 is supplying hand-washing water, and does not transmit the supply information when the electrolyzed water supply device 2 is not supplying hand-washing water.

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 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 a worker (hereinafter referred to as a handwasher) who performs handwashing 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 as the handwasher. As mentioned above, the ID device 4 does not transmit identifier information when the worker is moving. For this reason, it is possible to prevent a worker who happens to pass by from being recognized as a hand washing person, and to improve the recognition accuracy of the hand washing person.

Alternatively, the monitoring information transmitting device 3 may supply a transmission request signal for 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 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 transmission device 3 (that is, near the electrolyzed water supply device 2). power consumption can be greatly reduced.

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

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

In addition, the monitoring information transmitting device 3 can start displaying a hand-washing moving image instructing the hand-washing procedure at the same time when the supply information is received. In this hand-washing moving image, according to the recommended hand-washing method, as the hand-washing time elapses, for example, after five seconds of kneading, washing between the fingers one by one, washing around the wrist for two seconds, etc. A step-by-step hand-washing procedure is displayed. It should be noted that the hand-washing procedure can be similarly displayed by switching the still image after the lapse of a predetermined time.

The monitoring information generator 31B confirms the reception time of the supply information, and if both the supply time of the hand-washing water and the reception time of the identifier information are equal to or greater than the hand-washing threshold value or within a predetermined range, the supply condition is satisfied and the hand-washing person recognizes that it has washed its hands, and the washing start time when the washing person started washing (i.e., started receiving supply information), and the washing end time when the washing person finished washing (i.e., finished receiving supply information), The selected identifier is transmitted to the aggregation device 5 as hand washing monitoring information. Further, when the monitoring information generation unit 31B recognizes that the person who was washing hands has stopped washing, the monitoring information generation unit 31B includes the washing stop time at which the washing was stopped in the washing monitoring information.

As shown in FIG. 7, the tallying device 5 has a computer configuration, and a control unit 51 composed of a CPU (Central Processing Unit), a ROM, and a RAM (not shown) controls the whole of the tallying device 5. is done.

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

Specifically, the external interface 52 of the control unit 51 aggregates the 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 tally the time spent by each user for hand washing.

Then, when the operator makes a display request for the totalized result via the operation input unit 54 , the control unit 51 puts together the totalized result into a graph or a list, and causes the display unit 55 to display it.

As a result, the administrator can visually confirm the number of times each user has washed their hands and the amount of time used for washing their hands, and can thoroughly manage hand washing.

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 transmitting process, the process proceeds to step S01.

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

If a positive result is obtained in step S01, then the monitoring information transmitting device 3 determines 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 wave intensity of the identifier information being received, selects the identifier information with the highest radio wave intensity, and proceeds to the next step S03.

In step S03, the monitoring information transmitting device 3 determines whether or not the supply of hand washing water has been stopped based on the supply information. If a negative result is obtained here, the monitoring information transmitting device 3 remains at step S03 and continues receiving the supply information.

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

In step S04, the monitoring information transmitting device 3 determines whether or not 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 has not been performed, and returns to step S01. On the other hand, if a positive result is obtained in step S04, this means that the person washes hands properly, and at this time the monitoring information transmitting device 3 proceeds to the next step S05.

In step S05, when 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 washing monitoring information, the process proceeds to the end step and ends the process.
