Description

[Technical field]

[0001] The present disclosure relates to a beverage serving quality monitoring system and a beverage serving quality monitoring method. [Background technology]

[Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-103999 A Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned beverage dispenser system includes a plurality of sensors that measure the status of each part of the beverage dispenser system, and an external computer that receives the measurement results of the plurality of sensors, and transmits a message according to the measurement results to a mobile terminal of a person in charge of the beverage sales company. In this way, information regarding the status of each part of the beer dispenser is transmitted to the mobile terminal.

[0006] However, in the above-mentioned beverage dispenser system, since information on the sparkling beverage actually provided to the customer is not transmitted to an external computer, it is difficult to obtain information on the sparkling beverage itself that is provided. Therefore, it is not possible to fully grasp the condition in which the sparkling beverage is actually provided to the customer by the store that provides the sparkling beverage. Therefore, in order to grasp the condition in which the sparkling beverage is actually provided, it is necessary to interview the store or actually visit the store, so there is room for improvement in the management of the quality of the sparkling beverage in the store.

[0007] The present disclosure aims to provide a beverage serving quality monitoring system and a beverage serving quality monitoring method that can grasp the quality of carbonated beverages in a store with high accuracy while reducing the frequency of visits to the store. [Means for solving the problem]

[0008] The beverage serving quality monitoring system of the present disclosure is a beverage serving quality monitoring system that monitors the quality of beverages in a number of stores that serve beverages using a beverage server, wherein the beverage is a sparkling beverage comprising a liquid and foam placed on top of the liquid, and the system is equipped with a sensor unit including a sensor that measures at least one of the state of the liquid in the sparkling beverage being served and the state of the foam in the sparkling beverage being served, and a beverage serving information receiving unit that receives the state of the beverage measured by the sensor unit.

[0009] This beverage serving quality monitoring system includes a sensor unit including a sensor that measures at least one of the state of the liquid of the sparkling beverage to be served and the state of the foam of the sparkling beverage to be served. The sensor unit measures the state of the sparkling beverage to be served from the beverage server. The state of the sparkling beverage measured by the sensor unit is received by the beverage serving information receiving unit. Therefore, since it is possible to receive information on the sparkling beverage actually served from the beverage server, it is possible to obtain information on the sparkling beverage itself to be served. Therefore, since it is possible to obtain information on the sparkling beverage to be served, it is possible to fully grasp the state in which the sparkling beverage is actually served to customers in the store. As a result, it is possible to reduce the effort of interviewing or visiting the store to grasp the state of the provision of the sparkling beverage, and it is possible to easily and accurately grasp the quality of the provision of the sparkling beverage in the store. In addition, since the sensor of the sensor unit measures at least one of the state of the liquid of the sparkling beverage to be served and the state of the foam of the sparkling beverage to be served, it is possible to measure the sparkling beverage to be served with high accuracy.

[0010] The sensor unit may include a quantity measuring sensor that measures the distance between the top of the beverage container from which the beverage is dispensed and the top of the foam. In this case, the quantity measuring sensor measures the distance between the top of the beverage container and the top of the foam, thereby making it possible to know whether the amount of the sparkling beverage is appropriate. Therefore, the serving quality of the sparkling beverage can be known with a higher degree of accuracy.

[0011] The sensor unit may include a foam-liquid ratio measuring sensor that measures the ratio of the foam area to the liquid area in the beverage container from which the beverage is dispensed. In this case, since the foam-liquid ratio measuring sensor measures the foam-liquid ratio, it is possible to grasp whether the foam-liquid ratio in the provided sparkling beverage is appropriate. Therefore, it is possible to grasp whether the foam-liquid ratio is the recommended ratio, and therefore it is possible to grasp the quality of the provided sparkling beverage with a higher degree of accuracy.

[0012] The sensor unit may include a frosty mist measuring sensor that measures frosty mist generated at the boundary between the foam and the liquid in the beverage container from which the beverage is dispensed. Frosty mist is a tiny granular bubble generated between the liquid and the foam of the sparkling beverage, and it is known that when the frosty mist is stimulated during drinking, fine bubbles are regenerated. Therefore, when the sensor is provided with a frosty mist measuring sensor that measures frosty mist, it is possible to estimate the amount of foam regenerated in the sparkling beverage being served, and therefore the serving quality of the sparkling beverage can be grasped with a higher degree of accuracy.

[0013] The sensor unit may include a turbidity measuring sensor for measuring the turbidity of the liquid in the sparkling beverage. In this case, the turbidity measuring sensor measures the turbidity of the liquid in the sparkling beverage to be provided, so that it is possible to know whether the provided beverage is clear or not.

[0014] The sensor unit may include a liquid measuring sensor that measures the presence or absence of foreign matter in the beverage container from which the beverage is dispensed. In this case, the presence or absence of foreign matter in the beverage container can be detected by the liquid measuring sensor. Therefore, it is possible to warn establishments that use beverage containers with foreign matter attached thereto, thereby improving the quality of beverage provision.

[0015] The sensor unit may include an odor sensor that measures the presence or absence of an odor in the sparkling beverage and in the beverage container that the sparkling beverage is dispensed in. In this case, the odor sensor measures the presence or absence of an odor in the sparkling beverage and the beverage container, making it possible to quickly determine whether or not the sparkling beverage and the beverage container have an odor.

[0016] The sensor unit may include a racing measurement sensor that measures an annular bubble mark formed on the inner surface of the beverage container from which the sparkling beverage is dispensed. If this annular bubble mark (racing) is formed on the inner surface of the beverage container, it is considered that the beverage container has been properly cleaned and the original deliciousness of the sparkling beverage can be provided. Therefore, by using the racing measurement sensor to measure the racing that adheres to the inner surface of the beverage container, it is possible to know whether a delicious sparkling beverage has been provided.

[0017] The beverage serving quality monitoring method of the present disclosure is a beverage serving quality monitoring method that monitors the quality of beverages in a plurality of stores that serve sparkling beverages using a beverage server, and includes a step of measuring at least one of the state of the liquid in the sparkling beverage being served and the state of the foam in the sparkling beverage being served using a sensor of a sensor unit, and a step of receiving at least one of the measurement results of the liquid state and the measurement results of the foam state measured by the sensor from each of the plurality of stores.

[0018] In this beverage serving quality monitoring method, the quality of beverages in a plurality of stores is monitored, and the sensor measurement results of the sensor unit are received. Thus, like the beverage serving quality monitoring system described above, information on the sparkling beverage itself that is actually served can be received. Therefore, it is possible to fully grasp the state in which the sparkling beverage is actually served to customers in the store, thereby reducing the effort required to interview or visit the store to grasp the state of the sparkling beverage. And, the serving quality of the sparkling beverage in the store can be grasped easily and with high accuracy. In addition, at least one of the state of the liquid of the sparkling beverage to be served and the state of the foam of the sparkling beverage to be served is measured by the sensor of the sensor unit, so that the sparkling beverage to be served can be measured with high accuracy. Effect of the Invention

[0019] According to the present disclosure, it is possible to grasp the quality of sparkling beverages at a store with high accuracy while reducing the frequency of visits to the store. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, an embodiment of a beverage serving quality monitoring system and a beverage serving quality monitoring method according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions are omitted as appropriate. In addition, the drawings may be partially simplified or drawn in a schematic manner for ease of understanding, and the dimensional ratios and arrangement states are not limited to those shown in the drawings.

[0022] In the beverage serving quality monitoring system and beverage serving quality monitoring method of this embodiment, as an example, various sensors are attached around the beverage server in each of multiple stores, and the beverage serving quality in the multiple stores is monitored by receiving the measurement results of the various sensors.

[0023] In the beverage serving quality monitoring system and beverage serving quality monitoring method according to the present embodiment, the beverage serving quality at multiple stores is monitored, thereby making it possible to efficiently visit the stores for quality checks. In other words, since the beverage serving quality at multiple stores can be monitored remotely, the frequency of visits can be reduced for stores with high beverage serving quality, and guidance for quality improvement can be promptly given to stores with low beverage serving quality. For example, it is possible to encourage stores that do not clean their beverage servers enough to clean them.

[0024] The beverage serving quality monitoring system according to this embodiment is capable of remotely grasping the status of multiple beverage servers installed in multiple stores. Therefore, it becomes possible to grasp the timing of maintenance of multiple beverage servers. In addition, since the beverage serving quality monitoring system according to this embodiment is capable of grasping the usage status of the beverage servers, it is possible to detect when a beverage server is not being used due to a store going out of business, or when a beverage server has been moved from a store.

[0025] In the present disclosure, "beverage" refers to a drinkable liquid or semi-solid. "Beverage" includes alcoholic beverages such as beer, chuhai, happoshu, and wine, as well as non-alcoholic carbonated beverages and soft drinks. "Beverage" is, for example, a sparkling beverage. "Sparkling beverage" is, for example, a beverage that contains a fermented alcoholic beverage containing a gas such as carbon dioxide gas, and has a foaming characteristic in which a layer of foam is formed on the liquid when poured into a beverage container, and a foam retention characteristic in which the formed foam is maintained for a certain period of time or more.

[0026] A sparkling beverage is, for example, a beverage that has a NIBEM value of 50 seconds or more according to the EBC (European Brewery Convention) method. The NIBEM value is an index value that indicates the foam retention characteristics of a beverage. The sparkling beverage may be a beer-taste beverage. Beer-taste beverages include beverages that taste like beer and beverages that give the drinker the sensation of drinking beer. Beer-taste beverages with an alcohol content of 1% or more are also called beer-taste alcoholic beverages.

[0027] Furthermore, beer-taste beverages include malt fermented beverages that use malt as an ingredient, such as beer, happoshu, non-alcoholic beer, and liqueurs (e.g., beverages classified as "liqueurs (sparkling) (1)" under the Liquor Tax Act), as well as beer-taste beverages that do not use barley or malt as an ingredient (e.g., beverages classified as "other brewed alcoholic beverages (sparkling) (1)" under the Liquor Tax Act). Note that a "sparkling beverage" may be a beverage other than a beer-taste beverage. In this embodiment, as an example, an example will be described in which the sparkling beverage is beer and the liquid in the sparkling beverage is beer liquid.

[0028] "Quality of beverage provision" and "serving quality" include the quality of the beverage itself that is served, and the quality of the beverage server. "Quality of beverage provision" and "serving quality" may further include the quality of the establishment where the beverage is served (e.g., the temperature inside the establishment). An "establishment" is an establishment where beverages are served to customers (drinkers). "Establishment" may include, for example, eating and drinking establishments such as izakayas, restaurants, or beer gardens, or event venues where beverages are served.

[0029] Fig. 1 is a block diagram showing an example of a functional configuration of a beverage serving quality monitoring system 1 according to this embodiment. The beverage serving quality monitoring system 1 is, for example, a computer system used to monitor the quality of beverage serving in a plurality of stores. For example, the beverage serving quality monitoring system 1 may be configured as a single computer, and may include, for example, a mobile terminal such as a tablet terminal, a highly functional mobile phone (smartphone), or a laptop-type personal computer, or may include an information terminal such as a stationary personal computer. Alternatively, the beverage serving quality monitoring system 1 may be a distributed processing system configured by a plurality of computers, or may be a client-server system, or a cloud system.

[0030] The beverage serving quality monitoring system 1 may include a beverage serving quality monitoring program. The beverage serving quality monitoring program according to this embodiment includes, for example, a main module, a data acquisition module, an image analysis module, a judgment module, and an output module. The main module is a module that comprehensively manages the functions of the beverage serving quality monitoring system 1. Each functional component of the beverage serving quality monitoring system 1 functions by executing the data acquisition module, the image analysis module, the judgment module, and the output module. The beverage serving quality monitoring program may be provided by being fixedly recorded on a tangible recording medium such as a CD-ROM, a DVD-ROM, or a semiconductor memory. The beverage serving quality monitoring program may also be provided via a communication network as a data signal superimposed on a carrier wave.

[0031] The beverage serving quality monitoring system 1 includes, for example, a server 2. The exemplary server 2 is capable of communicating with each of a beverage server sensor 20 fixed to a beverage server 10 arranged in each of a plurality of stores, and a sensor unit 40 arranged outside the beverage server 10 as a separate entity from the beverage server 10. The "sensor unit" refers to one or more sensors that measure the state of a beverage being served. The "beverage being served" includes both the beverage before being dispensed from the beverage server 10 and the beverage after being dispensed from the beverage server 10.

[0032] In the example of FIG. 1, store A1 equipped with one beverage server 10 and store A2 equipped with multiple beverage servers 10 are shown as examples of multiple stores. However, the number of stores targeted by beverage serving quality monitoring system 1 may be three or more, or in some cases may be one. Furthermore, the number of beverage servers 10 arranged in a store is not particularly limited. Furthermore, the number of beverage servers 10 and the number of sensor units 40 in a store may be the same or different.

[0033] The server 2 includes, as functional components, for example, a beverage provision information receiving unit 3, a data analysis unit 4, a data display unit 5, and an alert output unit 6. The beverage provision information receiving unit 3 receives beverage server status information D1 indicating the status of the beverage server 10 from the beverage server 10. Furthermore, the beverage provision information receiving unit 3 receives outside-server beverage status information D2 indicating information on the status of the beverage outside the beverage server 10 from the sensor unit 40. The outside-server beverage status information D2 may be, for example, the status of the beverage dispensed from the beverage server 10, or the status of the beverage before it is supplied to the beverage server 10.

[0034] The data analysis unit 4 is, for example, a functional element that analyzes the beverage server status information D1 and the beverage status information outside the server D2 received by the beverage provision information receiving unit 3. As one example, the data analysis unit 4 may determine whether the beverage server status information D1 is good or bad, and whether the beverage status information outside the server D2 is good or bad. As a specific example, the data analysis unit 4 may determine that a store is passed if both the beverage server status information D1 and the beverage status information outside the server D2 meet a predetermined standard, and may determine that a store is failed if either the beverage server status information D1 or the beverage status information outside the server D2 does not meet the standard.

[0035] The data display unit 5 is a functional element that displays the analysis results of the beverage server status information D1 and the outside-server beverage status information D2 by the data analysis unit 4. The data display unit 5 may display the analysis results as a dashboard including at least one of a pie chart, a bar graph, and a line graph, for example. The data analysis unit 4 and the data display unit 5 may be configured with BI tools (Business Intelligence tools).

[0036] The alert output unit 6 is a functional element that outputs, for example, information about a store that has been determined to have failed by the data analysis unit 4. As one example, the alert output unit 6 outputs information about the store that has been determined to have failed by the data analysis unit 4 to an information terminal T. The information terminal T is, for example, a mobile terminal of the headquarters (as one example, a person in charge of a company that provides beverages), and the information about the store that has been determined to have failed by the alert output unit 6 is output to the mobile terminal.

[0037] The alert output unit 6 outputs the information of the store to the information terminal T, for example, by email or by a beverage serving quality monitoring program application. This allows, for example, a person in charge of a beverage supplying company to quickly grasp the information of a store that has been judged to be unsatisfactory, and therefore makes it possible to provide prompt guidance to the store.

[0038] 2 is a diagram showing an example of the hardware configuration of the beverage provision quality monitoring system 1 (for example, the server 2 and the terminals). As an example, each of the above-mentioned functional elements of the server 2 is realized by the hardware configuration. For example, the server 2 includes a processor 2b, a main memory unit 2c, an auxiliary memory unit 2d, a communication module 2f, a display 2g, and an input interface 2h.

[0039] The processor 2b is a calculation device that executes an operating system and application programs. The main memory 2c is composed of, for example, ROM or RAM, and temporarily stores loaded programs or calculation results. The auxiliary memory 2d is composed of, for example, flash memory or a hard disk, and permanently stores programs or data. The communication module 2f is composed of a wireless communication module or a network card, and transmits and receives data to and from other computers. The display 2g is composed of a touch panel or monitor, and is a device that accepts input of data or instructions so that the user can see it.

[0040] For example, each of the aforementioned functional elements of the server 2 (beverage provision information receiving unit 3, data analyzing unit 4, data display unit 5, and alert output unit 6) is realized by loading predetermined software (for example, the aforementioned beverage provision quality monitoring program) into the processor 2b or main memory unit 2c and executing that software. The processor 2b operates the communication module 2f, display 2g, or input interface 2h in accordance with the software, and reads and writes data in the main memory unit 2c or auxiliary memory unit 2d. Data and the like that is organized into a database is stored in the main memory unit 2c or auxiliary memory unit 2d.

[0041] As described above, the server 2 may be configured with one computer or multiple computers. For example, when the server 2 is configured with multiple computers, the multiple computers are connected to each other via a communication network such as the Internet or an intranet to logically configure one server 2.

[0042] Next, an exemplary beverage providing device 11 including a beverage server 10 will be described with reference to Figures 1 and 3. In this embodiment, the beverage providing device 11 is disposed in each of stores A1 and A2. The exemplary beverage providing device 11 is a device that dispenses a beverage (beer, as an example) from a faucet 10b of the beverage server 10 in response to a customer's order or the like.

[0043] In addition to the beverage server 10 of this embodiment, the beverage providing device 11 also includes a cylinder 12, a pressure reducing valve 13, a carbon dioxide hose 14, a barrel 15 containing beer, a head 16, and a hose 17. The cylinder 12 is, for example, a container filled with carbon dioxide gas at high pressure, and has the function of pushing the beverage inside the barrel 15 out to the beverage server 10, as well as the function of maintaining an appropriate amount of carbon dioxide gas contained in the beverage inside the barrel 15.

[0044] Carbon dioxide gas is filled in liquid form inside cylinder 12, for example, at a pressure of 6 to 8 MPa. Cylinder 12 is provided with, for example, a remaining amount indicator that displays the amount of carbon dioxide gas inside cylinder 12. By providing this remaining amount indicator, it becomes possible to recognize the amount of carbon dioxide gas inside cylinder 12.

[0045] The pressure reducing valve 13 is a device for adjusting the pressure (hereinafter referred to as gas pressure) of the carbon dioxide gas applied to the beverage inside the barrel 15. The pressure reducing valve 13 includes a residual pressure indicator 13b that displays the residual pressure of the carbon dioxide gas inside the cylinder 12, and an operating unit 13c for adjusting the gas pressure.

[0046] The barrel 15 is a container filled with a beverage. For example, a liquid temperature detector 15b can be attached to the surface of the barrel 15, and the liquid temperature detector 15b can detect the temperature of the beverage in the barrel 15. In addition, a tube 15c through which the beverage flows and a nozzle 15d are provided inside the barrel 15.

[0047] The head 16 has a function of, for example, sending the carbon dioxide gas inside the cylinder 12 into the inside of the barrel 15 via the pressure reducing valve 13 and the carbon dioxide hose 14, and sending the beverage inside the barrel 15 to the beverage server 10. As an example, the head 16 includes a main body 16f, an operating handle 16b that can open and close the flow paths of the carbon dioxide gas and the beverage by moving it up and down, a gas joint 16c connected to the carbon dioxide hose 14, and a beverage joint 16d connected to the hose 17.

[0048] For example, with the lower part of head 16 connected to nozzle 15d, lowering operation handle 16b of head 16 opens the flow paths of carbon dioxide hose 14 and hose 17, and raising operation handle 16b closes the flow paths of carbon dioxide hose 14 and hose 17. Gas joint 16c and beverage joint 16d are detachable from main body 16f, and because gas joint 16c, beverage joint 16d and main body 16f are disassembled, head 16 is designed to be easily cleaned.

[0049] Beverage server 10 is connected to head 16 via hose 17, and has the function of cooling the beverage delivered from barrel 15 via head 16 and hose 17. Beverage server 10 is, for example, an electric-cooling instant-cooling server. Inside beverage server 10, cooling device 10c is provided which functions as a supply device that cools the beverage from hose 17 and supplies the beverage to faucet 10b.

[0050] The beverage server 10 includes a pedestal 10j on which a beverage container for a beverage to be dispensed from the faucet 10b can be placed. By pulling the faucet 10b with the beverage container placed on the pedestal 10j, the beverage can be dispensed into the beverage container. The pedestal 10j not only places the beverage container on but also receives and contains any spilled beverage. The pedestal 10j is detachable from the beverage server 10 and is, for example, periodically removed from the beverage server 10 and cleaned.

[0051] The cooling device 10c includes a water tank 10d that contains cooling water therein, and a spiral beverage pipe 10f that is connected to a hose 17 and disposed inside the water tank 10d. A refrigerant pipe 10g that is connected to a refrigeration cycle device of the cooling device 10c is disposed on the inner surface of the water tank 10d. The refrigeration cycle device circulates the refrigerant through the refrigerant pipe 10g, which cools the cooling water around the refrigerant pipe 10g and forms ice 10h in the refrigerant pipe 10g. The ice 10h further cools the cooling water in the water tank 10d, thereby cooling the beverage inside the beverage pipe 10f.

[0052] In the above, an example was described in which the beverage server 10 is an electric-cooling type instant cooling server. However, the configuration of each part of the beverage server 10 is not limited to the above example, and the beverage server 10 may be a server other than an electric-cooling type instant cooling server. For example, the beverage server 10 may be an ice-cooling type instant cooling server, or a barrel storage type server in which the barrel 15, the head 16, and the hose 17 are provided inside the refrigerator.

[0053] The ice-cooled instant cooling server is a server in which ice is placed inside a cooling tank and the beverage pipe is cooled by the ice via a cold plate. On the other hand, the barrel-storage server is a server with a structure in which the barrel, head, and hose are stored in a refrigerator, and in this case, the hose 17 is cooled by the refrigerator.

[0054] Furthermore, the type of beverage server 10 installed in store A1 may be different from the type of beverage server 10 installed in store A2. Furthermore, the types of the multiple beverage servers 10 installed in store A2 may be different from each other. In the beverage serving quality monitoring system 1 and the beverage serving quality monitoring method according to this embodiment, the type of beverage server is not particularly limited. Below, specific examples of the beverage server sensor 20 and sensor unit 40 of the beverage serving quality monitoring system 1 are described.

[0055] As shown in Fig. 3 and Fig. 4, each of the beverage server sensor 20 and the sensor unit 40 is configured to include, for example, a plurality of sensors. First, the sensors that configure the beverage server sensor 20 will be described. The beverage server sensor 20 includes, for example, at least one of a water tank temperature sensor 21, an ice production amount measurement sensor 22, a server power supply current sensor 23, a ground fault circuit interrupter operation sensor 24, a stirring motor rotation speed sensor 25, a beverage line attachment sensor 26, a water tank water level sensor 27, a pedestal water volume sensor 28, a fan motor current measurement sensor 29, an outer surface condensation sensor 30, a water tank water quality sensor 31, a refrigeration device current measurement sensor 32, a pouring lever open / close sensor 33, a faucet outlet temperature sensor 34, and a communication unit 35.

[0056] The communication unit 35 has, for example, a communication function with the server 2. The communication unit 35 may have a wireless communication function with the server 2. The communication unit 35 transmits the measurement results measured by each sensor constituting the beverage server sensor 20 to the server 2. The timing of transmitting the measurement results to the server 2 is not particularly limited, and may be, for example, in real time, continuously transmitted as time-series data, or transmitted at regular intervals.

[0057] The communication unit 35 transmits a server individual number (identification ID) uniquely assigned to each beverage server 10 to the server 2 together with the measurement results. The communication between the beverage server sensor 20 and the server 2 by the communication unit 35 may be wireless communication or wired communication. The communication means between the beverage server sensor 20 (communication unit 35) and the server 2 is not particularly limited.

[0058] Water tank temperature sensor 21 measures the temperature of water tank 10d. Water tank temperature sensor 21 measures at least one of the temperature of water tank 10d itself and the temperature of the cooling water contained in water tank 10d. For example, water tank temperature sensor 21 is placed at a position not in contact with ice 10h to avoid being affected by ice 10h.

[0059] The ice making amount measuring sensor 22 measures the amount of ice 10h produced in the water tank 10d by the cooling device 10c. As an example, the ice making amount measuring sensor 22 is fixed to the inner surface of the water tank 10d. For example, the ice making amount measuring sensor 22 has a plurality of metal rods of different lengths, and measures the amount of ice 10h by detecting the conductive state of the plurality of metal rods. In this case, when the amount of ice 10h is less than a certain amount, the conductive state of the plurality of metal rods is maintained, but when the amount of ice 10h becomes equal to or greater than the certain amount, one metal rod is buried in the ice 10h, and the conductive state is interrupted. In other words, the ice making amount measuring sensor 22 measures whether the amount of ice 10h becomes equal to or greater than a certain amount by detecting the conductive state.

[0060] The server power conduction sensor 23 measures whether or not a predetermined voltage of power is being supplied to the beverage server 10. In this way, the server power conduction sensor 23 measures the power supply to the beverage server 10, thereby making it possible to measure the usage status of the beverage server 10. Since the voltage of the power handled by the beverage server 10 is, for example, AC 100V, the server power conduction sensor 23 measures whether or not AC 100V is being supplied to the beverage server 10. By the server power conduction sensor 23 measuring the state of the power to the beverage server 10, it is possible to know whether or not the beverage server 10 is being used appropriately in the store.

[0061] The earth leakage breaker operation sensor 24 measures the operation state of the earth leakage breaker of the beverage server 10. The earth leakage breaker of the beverage server 10 detects the occurrence of an electric leakage in the beverage server 10, and when an electric leakage is detected, cuts off the electric circuit inside the beverage server 10. For example, the earth leakage breaker operation sensor 24 measures whether the earth leakage breaker of the beverage server 10 is activated or not.

[0062] Agitation motor rotation speed sensor 25 measures the rotation speed of a motor that rotates an agitation member (a propeller, for example) that agitates the cooling water in water tank 10d. As a specific example, agitation motor rotation speed sensor 25 obtains information on the rotation speed and rotation state (for example, whether the rotation is high speed or low speed) of the motor from a controller that controls the rotation of the motor.

[0063] The beverage line attachment sensor 26 measures whether or not a beverage pipe 10f is attached to the beverage server 10. As a specific example, a plurality of beverage pipes 10f are detachably attached to the beverage server 10, and the beverage line attachment sensor 26 measures which of the plurality of beverage pipes 10f is attached. This makes it possible to grasp the attachment state of the beverage pipe 10f (whether or not the beverage pipe 10f is attached to the water tank 10d).

[0064] Water tank water level sensor 27 measures the water level of the cooling water contained in water tank 10d. For example, water tank water level sensor 27 measures whether the water level of the cooling water contained in water tank 10d is equal to or higher than a predetermined amount. By water tank water level sensor 27 measuring the water level of the cooling water in this manner, it is possible to know whether the water level of the cooling water in water tank 10d is appropriate.

[0065] The pedestal water volume sensor 28 measures the amount of water in the pedestal 10j of the beverage server 10. For example, the pedestal water volume sensor 28 is attached to the pedestal 10j or its periphery, and measures whether the amount of water contained in the pedestal 10j is equal to or greater than a certain amount. It is preferable that the amount of water contained in the pedestal 10j is smaller, and it is understood that the smaller the amount of water in the pedestal 10j, the more frequently the pedestal 10j is cleaned. Therefore, by the pedestal water volume sensor 28 measuring the amount of water in the pedestal 10j, it is possible to know whether the pedestal 10j is being properly cleaned.

[0066] In addition, since the temperature of the water tank 10d is lower than room temperature, water vapor in the air may liquefy, and the liquefied water vapor may adhere to the surface of the water tank 10d as condensed water. When this condensed water enters the water tank 10d, the water level inside the water tank 10d rises. The water tank 10d is provided with an overflow drain pipe (not shown) at the top, and when the water level inside the water tank 10d reaches this drain pipe, the water flows out of the drain pipe, and is configured not to flow from the water tank 10d to the outside through any route other than the drain pipe, for example.

[0067] The drain pipe for overflow of the water tank 10d is connected to the pedestal 10j, and water overflowing from the water tank 10d flows into the pedestal 10j through the drain pipe. Therefore, for example, when the humidity is high, such as during the rainy season in summer, the pedestal 10j may become full in a few days. Therefore, when the pedestal water level sensor 28 measures whether the water level in the pedestal 10j is equal to or higher than a certain level, the humidity condition in the store and the cleaning status of the pedestal 10j can be remotely grasped.

[0068] The fan motor current measurement sensor 29 measures the current flowing to the fan motor that rotates and drives the fan constituting the refrigeration cycle device of the beverage server 10. The fan of the refrigeration cycle device of the beverage server 10 sends air to the condenser of the refrigeration cycle device, and efficiently exchanges heat of the refrigerant with the refrigerant tube 10g in the condenser. The fan motor current measurement sensor 29 measures the current flowing to the fan motor, thereby making it possible to grasp the load state on the fan motor.

[0069] The outer surface condensation sensor 30 is, for example, a moisture sensor fixed to the surface of the housing of the beverage server 10. As an example, the outer surface condensation sensor 30 includes two metal members. The outer surface condensation sensor 30 measures condensation by detecting conduction between the two metal members when water droplets are formed between the two metal members.

[0070] The water tank water quality sensor 31 measures the quality of the cooling water contained in the water tank 10d of the beverage server 10. For example, the water tank water quality sensor 31 measures whether the quality of the cooling water in the water tank 10d is close to pure water. The water tank water quality sensor 31 may also measure the turbidity of the cooling water in the water tank 10d. In this way, the water tank water quality sensor 31 measures the quality of the cooling water in the water tank 10d, thereby making it possible to grasp the condition of the cooling water in the water tank 10d. The refrigeration device current measurement sensor 32 measures, for example, the current flowing through the motor of the above-mentioned condenser (compressor) of the refrigeration cycle device of the beverage server 10.

[0071] The pouring lever open / close sensor 33 measures the movement of the lever of the faucet 10b of the beverage server 10. The pouring lever open / close sensor 33 may also be disposed inside the faucet 10b and detect the movement of a slide valve that moves in response to the operation of the lever. The pouring lever open / close sensor 33 detects the lever operation of the faucet 10b, thereby making it possible to measure the open / closed state of the beverage flow path inside the faucet 10b. The faucet outlet temperature sensor 34 measures the temperature of the outlet portion of the faucet 10b where the beverage is poured from the faucet 10b.

[0072] As described above, the beverage server sensor 20 includes at least one of the water tank temperature sensor 21, ice production amount measurement sensor 22, server power supply current sensor 23, earth leakage circuit breaker activation sensor 24, mixing motor rotation speed sensor 25, beverage line attachment sensor 26, water tank water level sensor 27, basin water volume sensor 28, fan motor current measurement sensor 29, external surface condensation sensor 30, water tank water quality sensor 31, refrigeration unit current measurement sensor 32, pouring lever opening / closing sensor 33, and faucet outlet temperature sensor 34.

[0073] This enables the beverage server sensor 20 to measure and transmit to the server 2 at least one of the following: the temperature of the water tank 10d, the level and quality of the cooling water, the amount of ice 10h, the power supply status to the beverage server 10, the status of the earth leakage circuit breaker, the status of the stirring motor, the status of the beverage pipe 10f, the status of the cooling device 10c, and the operating status of the faucet 10b.

[0074] Next, the sensor unit 40 will be described. The sensor unit 40 measures the state of a beverage provided from the beverage server 10, for example, at a position separated from the beverage server 10. The beverage provision quality monitoring system 1 includes, for example, a housing member 1A that houses a hose 17 at a position separated from the beverage server 10, and a barrel stand 1B on which a barrel 15 is placed. The housing member 1A is, for example, an external box that is disposed at a position separated from the beverage server 10, and is detachable from the hose 17.

[0075] For example, the sensor unit 40 includes a first sensor group 40A housed in the housing member 1A together with the hose 17, a second sensor group 40B arranged on the barrel stand 1B, and a sensor 41 fixed to the cylinder 12 and measuring the state of the gas in the cylinder 12. The sensor 41 may include, for example, a gas pressure measuring unit 41b that measures the gas pressure inside the cylinder 12, a remaining amount measuring unit 41c that measures the remaining amount of gas inside the cylinder 12, and a communication unit 41d.

[0076] The gas pressure measuring unit 41b measures, for example, the primary pressure and the secondary pressure of the pressure reducing valve 13 attached to the cylinder 12. The communication unit 41d has a communication function with the server 2, similar to the communication unit 35 described above. Therefore, for example, the gas pressure of the cylinder 12 measured by the gas pressure measuring unit 41b and the remaining amount of gas in the cylinder 12 measured by the remaining amount measuring unit 41c are transmitted to the server 2 by the communication unit 41d.

[0077] The sensor unit 40 includes, inside the storage member 1A, a temperature measurement sensor 42, a flow rate sensor 43, a conductivity measurement sensor 44, a turbidity measurement sensor 45, an air bubble measurement sensor 46, a pressure measurement sensor 47, an outside air temperature measurement sensor 48, and a communication unit 49. The communication unit 49 has a communication function with the server 2, similar to the communication unit 35 described above. Therefore, the measurement results measured by each sensor of the sensor unit 40 arranged inside the storage member 1A are transmitted to the server 2 by the communication unit 49.

[0078] The temperature measuring sensor 42 measures the temperature of the beverage passing through the inside of the hose 17. The temperature measuring sensor 42 is fixed to the hose 17 while being in contact with the hose 17, and may be fixed to the hose 17 so as to embrace the hose 17, for example. The temperature measuring sensor 42 may include a metal joint, and the hose 17 may be connected to both ends of the metal joint. In this case, the temperature measuring sensor 42 is attached to the hose 17 via the metal joint, so that it is possible to more accurately grasp the temperature of the beverage passing through the hose 17.

[0079] As an example, the flow rate sensor 43 is a capacitive non-contact sensor that measures the flow rate of the beverage passing through the inside of the hose 17. As an example, the flow rate sensor 43 is a flow meter attached to the hose 17. As an example, the flow rate sensor 43 is fixed to the hose 17 in a state in which the hose 17 is sandwiched. By the flow rate sensor 43 measuring the flow rate of the beverage passing through the hose 17, it becomes possible to estimate the amount of the beverage dispensed, the amount of the beverage consumed, and the sales of the beverage per certain period (e.g., one day).

[0080] The conductivity measuring sensor 44 measures the conductivity of the beverage passing through the inside of the hose 17. For example, the conductivity measuring sensor 44 includes a pair of electrodes and a joint, and the hose 17 is connected to both ends of the joint. The conductivity measuring sensor 44 measures the conductivity of the beverage by measuring the electrical resistance between the pair of electrodes. Since the conductivity differs depending on the type of beverage (liquid type), by the conductivity measuring sensor 44 measuring the conductivity of the beverage, it becomes possible to determine the type of beverage passing through the hose 17.

[0081] The turbidity measuring sensor 45 measures the turbidity of the beverage passing through the inside of the hose 17. For example, the turbidity measuring sensor 45 is an optical sensor fixed to the hose 17 so as to hold the hose 17. In this case, the turbidity measuring sensor 45 includes a light emitting unit and a light receiving unit, and the light emitting unit irradiates light onto the inside of the hose 17, and the light receiving unit receives the light that is transmitted (or reflected) through the hose 17 in response to the irradiation. The turbidity measuring sensor 45 then measures the turbidity of the beverage in the hose 17 from the amount of light received by the light receiving unit.

[0082] The air bubble measuring sensor 46 measures air bubbles in the beverage passing through the inside of the hose 17. For example, an optical sensor similar to the turbidity measuring sensor 45 can be used as the air bubble measuring sensor 46. As an example, the air bubble measuring sensor 46 irradiates light from a light emitting unit to the inside of the hose 17, and measures the presence or absence of air bubbles from the state of the light received by the light receiving unit in response to the irradiation. For example, the air bubble measuring sensor 46 determines that air bubbles have been generated when the intensity of the light received by the light receiving unit changes continuously. In this way, the air bubble measuring sensor 46 measures air bubbles inside the hose 17, making it possible to measure the presence or absence of foreign matter, foaming, or supersaturation inside the hose 17.

[0083] Pressure measurement sensor 47 measures, for example, the pressure of the beverage passing through hose 17. As an example, pressure measurement sensor 47 includes a joint connected to hose 17 and a pressure sensor built into the joint. Pressure measurement sensor 47 measures the pressure of the beverage inside hose 17 while fixed to hose 17 via the joint. This makes it possible to know whether excessive pressure is being applied to hose 17, and therefore makes it possible to know whether the installation conditions of hose 17 and beverage server 10 are appropriate.

[0084] The outside air temperature measuring sensor 48 is a thermometer that measures the temperature of the outside air outside the beverage server 10. The outside air temperature measuring sensor 48 measures the temperature of the location where the beverage server 10 is installed. The outside air temperature measuring sensor 48 may measure humidity as well as temperature. By the outside air temperature measuring sensor 48 measuring the temperature around the beverage server 10, it is possible to determine whether the installation environment of the beverage server 10 is appropriate.

[0085] Although various sensors of the sensor unit 40 provided in the storage member 1A have been described above, the sensors of the sensor unit 40 provided in the storage member 1A are not limited to the above examples and can be changed as appropriate. For example, a GPS for measuring the position of the beverage server 10, or a time measurement (clock) may be provided in the storage member 1A.

[0086] Furthermore, various sensors of the sensor unit 40 provided in the housing member 1A may be included in the beverage server sensor 20. That is, as a sensor of the beverage server sensor 20, a sensor that measures the beverage in the hose 17 passing through the inside of the beverage server 10 (for example, a sensor similar to the above-mentioned temperature measurement sensor 42, etc.) may be provided.

[0087] For example, the sensor unit 40 may include a sensor arranged on the barrel stand 1B, and the sensor includes, for example, a barrel liquid temperature measuring sensor 51, a remaining amount measuring sensor 52, and a communication unit 53. The communication unit 53 has a communication function with the server 2, similar to the communication unit 35 described above. Therefore, the measurement results measured by each sensor of the sensor unit 40 arranged on the barrel stand 1B are transmitted to the server 2 by the communication unit 53.

[0088] As an example, the barrel stand 1B has a mounting portion 1b on which the barrel 15 is placed, and the second sensor group 40B of the sensor unit 40 is embedded in the mounting portion 1b. For example, the mounting portion 1b is disk-shaped, and the second sensor group 40B is fixed to the center of the mounting portion 1b. In this case, when the barrel 15 is placed on the mounting portion 1b, the barrel liquid temperature measuring sensor 51 of the second sensor group 40B measures the temperature of the barrel 15, and the remaining amount measuring sensor 52 measures the remaining amount of the barrel 15.

[0089] The keg liquid temperature measuring sensor 51 may, for example, estimate the temperature of the beverage inside the keg 15 by measuring the temperature of the bottom of the keg 15. The remaining amount measuring sensor 52 measures the remaining amount of beverage in the keg 15 from the weight of the keg 15 placed on the keg stand 1B. By the keg liquid temperature measuring sensor 51 measuring the temperature of the keg 15, it is possible to know the temperature of the beverage in the keg 15. Also, by the remaining amount measuring sensor 52 measuring, for example, time series data of the remaining amount in the keg 15, it is possible to know the consumption amount of the beverage in the keg 15.

[0090] The above describes the first sensor group 40A arranged in the housing member 1A of the sensor unit 40, the second sensor group 40B arranged in the barrel stand 1B, and the sensor 41. The various sensors constituting the first sensor group 40A, the various sensors constituting the second sensor group 40B, and the sensor 41 transmit the status of each part of the beverage provision device 11 to the server 2, so that it is possible to grasp the status of the beverage provision device 11 in the store A1 and the store A2 with high accuracy.

[0091] Next, an exemplary sensor unit 60 different from the sensor unit 40 will be described with reference to Figures 5 and 6. The sensor unit 60 measures, for example, the state of a beverage after it has been dispensed from the beverage server 10. The sensor unit 60 may be used together with the sensor unit 40, or the sensor unit 60 may be used alone.

[0092] An exemplary sensor unit 60 includes at least one of a real-time measurement sensor 60A, a stationary measurement sensor 60B, and a separate measurement device 60C. Note that Fig. 5 shows the real-time measurement sensor 60A, the stationary measurement sensor 60B, and the separate measurement device 60C in a schematic manner, and the shapes and sizes of the real-time measurement sensor 60A, the stationary measurement sensor 60B, and the separate measurement device 60C are not limited to the example in Fig. 5.

[0093] For example, the real-time measurement sensor 60A is disposed at a position where it can photograph the beverage dispensed from the faucet 10b. The stationary measurement sensor 60B is disposed at the receiving stand 10j, for example, and the separate measurement device 60C is disposed at a position away from the beverage server 10.

[0094] The real-time measurement sensor 60A measures the state of the beverage immediately after it is dispensed from the faucet 10b. The real-time measurement sensor 60A includes, for example, a plurality of sensors. As an example, the real-time measurement sensor 60A includes an amount measurement sensor 61, a foam / liquid ratio measurement sensor 62, a foam measurement sensor 63, a liquid measurement sensor 64, a beverage temperature measurement sensor in the container 65, a beverage container temperature measurement sensor 66, and a communication unit 67.

[0095] FIG. 7 shows an example of a beverage dispensed from the beverage server 10. As shown in FIG. 7, for example, a sparkling beverage B is dispensed from the beverage server 10 of this embodiment. As an example, the sparkling beverage B is dispensed into a beverage container C. The sparkling beverage B comprises a liquid B1 and foam B2 located on top of the liquid B1 inside the beverage container C. The beverage container C is a container capable of dispensing the sparkling beverage B, such as a mug, glass, or cup, for example.

[0096] The foam B2 of the sparkling beverage B contains so-called fine bubbles, which are different from coarse bubbles generated, for example, by the impact of the liquid B1 on the beverage container C. The fine bubbles are creamy bubbles that improve the design and mouthfeel of the sparkling beverage B, and it is preferable that a large amount of fine bubbles be generated in order to function as a lid to prevent the aroma or carbon dioxide gas from escaping from the liquid B1 and to prevent oxidation of the liquid B1.

[0097] As shown in Figures 5, 6 and 7, the amount measuring sensor 61 measures the amount of the sparkling beverage B in the beverage container C. The amount measuring sensor 61 is a sensor that measures the distance D between the top end C1 of the beverage container C and the top end B4 of the foam B2. The amount measuring sensor 61 may be, for example, a camera that measures whether or not there is foam B2, or may photograph the foam B2 of the dispensed sparkling beverage B. The amount measuring sensor 61 may be an optical height sensor that measures the distance D from the top end C1 of the beverage container C to the top end B4 of the foam B2. In this way, by measuring the distance D, it is possible to know whether the amount of the sparkling beverage B provided to the customer is appropriate.

[0098] The foam liquid ratio measuring sensor 62 measures the ratio of liquid B1 and foam B2 poured into the beverage container C. In other words, the foam liquid ratio measuring sensor 62 is a sensor that measures the ratio of the foam B2 area to the liquid B1 area in the beverage container C. The foam liquid ratio measuring sensor 62 is, for example, a camera that captures an image of the sparkling beverage B from the side of the beverage container C. In this case, the foam liquid ratio measuring sensor 62 calculates the ratio between the height H2 of the foam B2 and the height H1 of the liquid B1 in the captured image.

[0099] In this way, the foam-liquid ratio measuring sensor 62 measures the ratio of foam B2 to liquid B1, making it possible to grasp whether the amounts of foam B2 and liquid B1 are appropriate. As an example, if the ratio of foam B2 to liquid B1 is X:Y (X and Y are real numbers), then it is preferable that X=3 and Y=7. Therefore, the foam-liquid ratio measuring sensor 62 may, for example, measure the value of X / (X+Y) and determine whether the value of X / (X+Y) is within a predetermined range.

[0100] As a specific example, it may be determined whether the value of X / (X+Y) is 0.1 or more and 0.5 or less. As an example, when the value of X / (X+Y) is 0.1 or more and 0.5 or less, it is determined that the ratio of foam B2 to liquid B1 is good, and when the value of X / (X+Y) is less than 0.1 or exceeds 0.5, the ratio is determined to be not good. In this way, it is possible to determine whether the ratio of foam B2 to liquid B1 is appropriate.

[0101] The foam measurement sensor 63 measures, for example, the dispensed foam B2 itself. The foam measurement sensor 63 may be a camera that photographs the surface of the foam B2, and may measure the surface of the foam B2 from the photographed image. As a specific example, the foam measurement sensor 63 may measure the pattern of the photographed foam B2, and calculate the ratio of fine bubbles to coarse bubbles in the foam B2 from the measured pattern of the foam B2. This utilizes the characteristic that the pattern of a photographed image of fine bubbles is white, whereas the pattern of a photographed image of coarse bubbles is mottled. In this way, the foam measurement sensor 63 can be used to grasp the state of the foam B2.

[0102] The liquid measurement sensor 64 measures, for example, the poured liquid B1 itself. The liquid measurement sensor 64 may be a camera that photographs the liquid B1 from the side of the beverage container C. The liquid measurement sensor 64 may measure the presence or absence of air bubbles and foreign matter in the liquid B1. For example, if air bubbles are generated in the liquid B1 from the bottom or inner surface of the beverage container C, it is possible that minute foreign matter remains in the beverage container C, and therefore it is considered better to wash the beverage container C more thoroughly. Therefore, by the liquid measurement sensor 64 measuring the air bubbles and foreign matter in the liquid B1, it is possible to grasp the degree of washing of the beverage container C.

[0103] The in-container beverage temperature measuring sensor 65 is a sensor that measures the temperature of the beverage dispensed into the beverage container. For example, the in-container beverage temperature measuring sensor 65 may be a thermal camera that measures the temperature of the sparkling beverage B dispensed into the beverage container C. In this way, by the in-container beverage temperature measuring sensor 65 measuring the temperature of the dispensed sparkling beverage B, it becomes possible to determine whether the temperature of the dispensed sparkling beverage B is appropriate.

[0104] The beverage container temperature measuring sensor 66 is a sensor that measures the temperature of a beverage container. The beverage container temperature measuring sensor 66 may be, for example, a thermal camera that measures the temperature of a beverage container C placed on the receiving stand 10j of the beverage server 10. By the beverage container temperature measuring sensor 66 measuring the temperature of the beverage container C, it becomes possible to determine whether the temperature of the beverage container C is appropriate. The beverage container temperature measuring sensor 66 and the aforementioned in-container beverage temperature measuring sensor 65 may be integrated together.

[0105] In addition, the in-container beverage temperature measuring sensor 65 and the beverage container temperature measuring sensor 66 may be sensors other than a thermal camera. The communication unit 67 has a communication function with the server 2, similar to the communication unit 35 described above. Therefore, the measurement results measured by each sensor of the real-time measurement sensor 60A are transmitted to the server 2 by the communication unit 67.

[0106] The stationary measurement sensor 60B measures the sparkling beverage B and the beverage container C, for example, after the sparkling beverage B has been poured into the beverage container C. The stationary measurement sensor 60B may be provided with a switch, and the sensor 60B may measure the sparkling beverage B and the beverage container C for a fixed period of time (for example, 5 seconds) after the switch is operated.

[0107] The sensors constituting the stationary measurement sensor 60B include, for example, sensors that measure the weight of the sparkling beverage B and the beverage container C. In this case, the weights of the sparkling beverage B and the beverage container C can be ascertained, so that, for example, it can be determined whether a predetermined amount of the sparkling beverage B has been provided. In addition, part of the sensors constituting the separately installed measuring device 60C described later may be incorporated into the stationary measurement sensor 60B.

[0108] The real-time measurement sensor 60A and the stationary measurement sensor 60B, for example, measure the sparkling beverage B and beverage container C that are actually provided to a customer. In contrast, the separately installed measurement device 60C measures the sparkling beverage B and beverage container C that are not provided to a customer. In this way, by measuring both the sparkling beverage B that is provided to a customer and the sparkling beverage B that is not provided to a customer, it is possible to measure the sparkling beverage B with higher accuracy.

[0109] For example, the separate measuring device 60C measures the sparkling beverage B immediately after it is poured from the faucet 10b into the beverage container C. As a specific example, the separate measuring device 60C includes a stand 60d on which the beverage container C is placed, and a measuring unit 60f extending upward from the stand 60d. The beverage container C from which the sparkling beverage B has been poured from the faucet 10b is placed on the stand 60d of the separate measuring device 60C. The measuring unit 60f measures the sparkling beverage B by, for example, photographing the beverage container C placed on the stand 60d from the side.

[0110] Incidentally, the fine bubbles of the aforementioned sparkling beverage B are also generated from the frosty mist B3 that appears at the boundary between the liquid B1 and the bubbles B2. The frosty mist B3 is a mist-like layer that is provided at the boundary between the liquid B1 and the bubbles B2, and is, for example, a collection of fine bubbles with an outer diameter of 20 μm or less.

[0111] The amount of frosty mist B3 varies depending on the type (brand) of sparkling beverage B, the ingredients of sparkling beverage B, or the method of dispensing sparkling beverage B. Frosty mist B3 is generated by the application of gas pressure when sparkling beverage B is dispensed into beverage container C. Frosty mist B3 may be generated not only by gas pressure, but also by other factors such as ultrasound. Frosty mist B3 regenerates bubbles B2 when sparkling beverage B is consumed, for example, and thus has the effect of improving the retention of fine bubbles.

[0112] As a specific example, when sparkling beverage B is consumed, frosty mist B3 comes into contact with liquid B1, foam B2, or beverage container C and is stimulated, causing new foam B2 to be regenerated from frosty mist B3. As frosty mist B3 appears more clearly and the amount of frosty mist B3 increases, the amount of foam B2 regenerated increases. Therefore, it may be important to measure the amount of frosty mist B3 in order to improve the head retention of fine bubbles and regenerate foam B2.

[0113] For example, the sensor unit 60 includes a frosty mist measuring sensor 71 for measuring the amount of frosty mist B3, an odor sensor 72, a container state measuring sensor 73, a racing measuring sensor 74, and a communication unit 75 in the separately placed measuring device 60C. The communication unit 75 has a communication function with the server 2, similar to the communication unit 35 described above, and the measurement results measured by each sensor of the separately placed measuring device 60C are transmitted to the server 2 by the communication unit 75.

[0114] The frosty mist measuring sensor 71 is a sensor that measures the frosty mist B3 generated at the boundary between the foam B2 and the liquid B1. The frosty mist measuring sensor 71 may include a camera that captures an image of the vicinity of the boundary between the liquid B1 and the foam B2 from the side of the beverage container C. For example, the frosty mist measuring sensor 71 may measure the frosty mist B3 a certain time (for example, 60 seconds) after the sparkling beverage B is poured into the beverage container C. The frosty mist measuring sensor 71 may include a gas spraying section that sprays dry gas (dry air) onto the surface of the beverage container C. In this case, it becomes possible to perform an image capture with the camera in a state where condensation on the surface of the beverage container C has been removed by the dry gas.

[0115] Furthermore, the frosty mist measuring sensor 71 may obtain color parameters of the beverage container C, and measure the amount of frosty mist B3 using at least the color parameters of the frosty mist B3 among the color parameters of the sparkling beverage B. The color parameters are parameters that indicate color, and may be, for example, at least one of the L* value, a* value, and b* value of the color of the sparkling beverage B. In this way, by the frosty mist measuring sensor 71 measuring the frosty mist B3 of the sparkling beverage B, it becomes possible to grasp the strength of the regeneration power of fine bubbles for each beverage server 10 and each store.

[0116] The odor sensor 72 is a sensor that measures the presence or absence of an odor in the sparkling beverage B and the beverage container C. The odor sensor 72 may, for example, measure and digitize the odor from the sparkling beverage B and the beverage container C. By the odor sensor 72 measuring the odor of the sparkling beverage B and the beverage container C, it becomes possible to quickly determine whether or not an odor is occurring in the sparkling beverage B and the beverage container C.

[0117] It should be noted that the odor sensor 72 may be disposed in the real-time measurement sensor 60A. The container state measurement sensor 73 is a sensor that measures the beverage container C, for example, measuring the temperature of the beverage container C. The function of the container state measurement sensor 73 may be the same as, for example, the beverage container temperature measurement sensor 66 of the real-time measurement sensor 60A described above. Therefore, the container state measurement sensor 73 may be omitted.

[0118] The racing measurement sensor 74 measures annular bubble trails (racing) formed on the inner surface of the beverage container C. As illustrated in Figures 8(a), 8(b) and 8(c), the platform 60d is tilted when performing measurement using the racing measurement sensor 74. When performing measurement using the racing measurement sensor 74, for example, a lid F with an opening is attached to the beverage container C.

[0119] For example, a beverage container C is placed on a stand 60d, and the stand 60d is tilted to form an angle θ with respect to a horizontal plane H, and a sparkling beverage B is poured out of the beverage container C through an opening in a lid F. Then, when the tilt of the stand 60d is returned to its original position, the racing measurement sensor 74 photographs the beverage container C and measures bubbles B2 adhering to the inner surface of the beverage container C from the photographed image of the beverage container C. As an example, the racing measurement sensor 74 may measure the number of pixels of the bubbles B2 and the distribution state of the pixels of the bubbles B2 from the photographed image of the beverage container C, and measure the number, shape and size of annular bubble marks (racings) formed on the inner surface of the beverage container C.

[0120] When the above-mentioned lacing is formed on the inner surface of the beverage container C, it is considered that the beverage container C has been properly cleaned and is able to provide the original deliciousness of the sparkling beverage B. For this reason, by measuring the lacing adhering to the inner surface of the beverage container C with the lacing measurement sensor 74 as described above, it is possible to know whether or not the beverage server 10 is providing a delicious sparkling beverage B.

[0121] Next, an example of a beverage serving quality monitoring method according to the present embodiment will be described. As illustrated in Figures 1, 3 and 5, a beverage server sensor 20 is attached to a beverage server 10, and sensor units 40, 60 are installed around the beverage server 10. Then, the state of the beverage server 10 is measured by each sensor of the beverage server sensor 20, and the beverage server sensor 20 generates beverage server status information D1 (a process of generating beverage server status information).

[0122] Meanwhile, the state of the beverage provided from the beverage server 10 is measured by the sensor unit 40. For example, each sensor of the first sensor group 40A arranged in the housing member 1A measures the state of the beverage in the hose 17, while the second sensor group 40B arranged in the barrel stand 1B measures the state of the beverage in the barrel 15, and the sensor 41 measures the state of the cylinder 12. In this way, the state of the beverage provided is measured by each sensor of the sensor unit 40 provided outside the beverage server 10 to generate outside-server beverage state information D2 (step of generating outside-server beverage state information).

[0123] The state of the beverage dispensed from the beverage server 10 may also be measured by the sensor unit 60. For example, the sparkling beverage B is measured by the sensors of the real-time measurement sensor 60A, the sensors of the stationary measurement sensor 60B, and the sensors of the separately installed measurement device 60C. In this manner, the state of the dispensed beverage is measured by the sensors of the sensor unit 60 to generate beverage state information outside the server D2 (a step of generating beverage state information outside the server).

[0124] The generation of the beverage server status information D1 and the generation of the beverage outside server status information D2 are performed, for example, in a plurality of stores (as an example, each of store A1 and store A2). Then, the beverage provision information receiving unit 3 receives the beverage server status information D1 and the beverage outside server status information D2 from each of the plurality of stores (receiving step).

[0125] The beverage server status information D1 and the beverage outside the server status information D2 received by the beverage provision information receiving unit 3 are analyzed, for example, by the data analysis unit 4. For example, the data analysis unit 4 analyzes, from the acquired beverage server status information D1 and the beverage outside the server status information D2, whether the beverage server 10 and the provided beverage meet a minimum quality and whether the provided beverage is of high quality (analyzing step).

[0126] Whether the minimum quality is satisfied indicates, for example, whether each part of the beverage providing device 11 and the beverage container C have been properly cleaned, whether there is no odor, and whether the amount of the sparkling beverage B dispensed into the beverage container C is appropriate. Whether the beverage provided is of high quality indicates, for example, whether the ratio of liquid B1 to foam B2 in the beverage container C is appropriate, whether the temperatures of the outlet of the faucet 10b, the sparkling beverage B, and the beverage container C are appropriate, whether frosty mist B3 is generated, and whether lacing is formed. By receiving the beverage server status information D1 and the beverage status information outside the server D2, the beverage providing information receiving unit 3 can analyze both whether the above minimum quality is satisfied and whether the beverage provided is of high quality.

[0127] The data analysis unit 4 may also determine whether the beverage server status information D1 is good or bad, and whether the beverage outside the server status information D2 is good or bad. That is, the data analysis unit 4 may perform a pass / fail determination for the beverage server status information D1 and the beverage outside the server status information D2 for each of a plurality of stores.

[0128] After the data analysis unit 4 has analyzed the beverage server status information D1 and the beverage status information outside the server D2 as described above, the data display unit 5 displays the analysis results of the beverage server status information D1 and the beverage status information outside the server D2 by the data analysis unit 4 (process of displaying the analysis results).

[0129] For example, the data display unit 5 displays the analysis results on an information terminal at the headquarters. Furthermore, the data display unit 5 may display, for example, the analysis results for store A1 among the analysis results on an information terminal installed inside store A1. In this case, the beverage provider at store A1 can grasp the serving quality of the beverages from beverage server 10 by himself.

[0130] Moreover, the alert output unit 6 may output an alert to an information terminal (a step of outputting an alert). As an example, the alert output unit 6 may output information on a store that has been determined to be unsuccessful by the data analysis unit 4 to an information terminal. In this way, the series of steps is completed after the alert output unit 6 outputs an alert to the information terminal as necessary.

[0131] Next, the effects obtained from the beverage serving quality monitoring system 1 and beverage serving quality monitoring method according to the present embodiment will be described in detail. The beverage serving quality monitoring system 1 is equipped with sensor units 40, 60 including sensors that measure at least one of the state of the liquid B1 of the sparkling beverage B to be served and the state of the foam B2 of the sparkling beverage B to be served. The sensor units 40, 60 measure the state of the sparkling beverage B served from the beverage server 10.

[0132] The state of the sparkling beverage B measured by the sensor units 40, 60 is received by the beverage provision information receiving unit 3. Therefore, since information on the sparkling beverage B actually provided can be received from the beverage server 10, it is possible to obtain information on the sparkling beverage B itself that is being provided. Therefore, since information on the sparkling beverage B that is being provided can be obtained, it is possible to fully grasp the state in which the sparkling beverage B is actually being provided to the customer in the store.

[0133] As a result, it is possible to reduce the time and effort required to interview or visit the store to understand the state of provision of the sparkling beverage B, and to easily and accurately understand the provision quality of the sparkling beverage B in the store. Furthermore, the sensors of the sensor units 40, 60 measure at least one of the state of the liquid B1 of the sparkling beverage B to be provided and the state of the foam B2 of the sparkling beverage B to be provided, making it possible to measure the sparkling beverage B to be provided with high accuracy.

[0134] The sensor unit 60 may include an amount measuring sensor 61 that measures the distance D between the top end C1 of the beverage container C into which the sparkling beverage B has been poured and the top end B4 of the foam B2. In this case, the amount measuring sensor 61 measures the distance D between the top end C1 of the beverage container C and the top end B4 of the foam B2, thereby making it possible to know whether the amount of the sparkling beverage B is appropriate. Therefore, the serving quality of the sparkling beverage B can be known with higher accuracy.

[0135] The sensor unit 60 may include a foam / liquid ratio measuring sensor 62 that measures the ratio of the foam B2 area to the liquid B1 area in the beverage container C into which the sparkling beverage B has been poured. In this case, the foam / liquid ratio measuring sensor 62 measures the ratio of the foam B2 to the liquid B1, so that it is possible to know whether the ratio of the foam B2 to the liquid B1 in the sparkling beverage B provided is appropriate. Therefore, it is possible to know whether the ratio of the foam B2 to the liquid B1 is the recommended ratio, so that the quality of the provided sparkling beverage B can be known with high accuracy.

[0136] The sensor unit 60 may include a frosty mist measuring sensor 71 that measures frosty mist B3 generated at the boundary between foam B2 and liquid B1 in the beverage container C into which the sparkling beverage B has been poured. The frosty mist B3 is a minute granular bubble generated between the liquid B1 and foam B2 of the sparkling beverage B, and it is known that when the frosty mist B3 is stimulated during drinking, finer bubbles B2 are regenerated. Therefore, when the frosty mist measuring sensor 71 that measures the frosty mist B3 is provided, the amount of regeneration of foam B2 in the sparkling beverage B provided can be estimated, and the serving quality of the sparkling beverage B can be grasped with higher accuracy.

[0137] For example, the foam B2 and liquid B1 may be measured within 10 seconds after the sparkling beverage B is dispensed. The frosty mist B3 may be measured 20 to 90 seconds after the sparkling beverage B is dispensed. In this case, the measurement of the sparkling beverage B can be performed at a more appropriate timing (in the above example, the foam B2 and liquid B1 are measured within 10 seconds after the sparkling beverage B is dispensed, and the frosty mist B3 is measured 20 to 90 seconds after the sparkling beverage B is dispensed). As a result, a more accurate measurement result can be obtained for the measurement of the sparkling beverage B.

[0138] The sensor unit 40 may include a turbidity measurement sensor 45 that measures the turbidity of the liquid B1 in the sparkling beverage B. In this case, the turbidity measurement sensor 45 measures the turbidity of the liquid B1 in the sparkling beverage B to be provided, so it is possible to know whether the sparkling beverage B to be provided is cloudy or not. Alternatively, the liquid measurement sensor 64 of the sensor unit 60 may measure the turbidity of the liquid B1.

[0139] The sensor unit 60 may include an odor sensor 72 that measures the presence or absence of an odor in the sparkling beverage B and the beverage container C into which the sparkling beverage B is dispensed. In this case, by the odor sensor 72 measuring the presence or absence of an odor in the sparkling beverage B and the beverage container C, it is possible to quickly determine whether or not the sparkling beverage B and the beverage container C have an odor.

[0140] As shown in Fig. 8, the sensor unit 60 may include a racing measurement sensor 74 that measures annular foam marks formed on the inner surface of a beverage container C from which a sparkling beverage B has been poured. If such annular foam marks (racing) are formed on the inner surface of the beverage container C, it is considered that the beverage container C has been properly cleaned and the original deliciousness of the sparkling beverage B has been provided. Therefore, by using the racing measurement sensor 74 to measure the lacing adhering to the inner surface of the beverage container C, it is possible to know whether a delicious sparkling beverage B has been provided.

[0141] In the beverage serving quality monitoring method according to the present embodiment, the quality of the sparkling beverage B in a plurality of stores is monitored, and the sensor measurement results of the sensor units 40 and 60 are received. Thus, like the beverage serving quality monitoring system 1, information on the sparkling beverage B itself that is actually served can be received. Therefore, it is possible to fully grasp the state in which the sparkling beverage B is actually served to customers in the store, and the effort of interviewing or visiting the store to grasp the state of the sparkling beverage B can be reduced. And, the serving quality of the sparkling beverage B in the store can be grasped easily and with high accuracy. In addition, at least one of the state of the liquid B1 of the sparkling beverage B to be served and the state of the foam B2 of the sparkling beverage B to be served is measured by the sensor of the sensor units 40 and 60, so that the sparkling beverage B to be served can be measured with high accuracy.

[0142] In particular, in this embodiment, by measuring the state of the beverage before it reaches beverage server 10 (for example, the state of the beverage contained in hose 17 or barrel 15), the state of beverage server 10, and the state of the beverage dispensed from beverage server 10 in each of a plurality of stores, it is possible to grasp the serving quality of the beverage in a series of processes up to the point where the beverage is served to the customer in each of a plurality of stores. Therefore, since information on the entire serving of beverages, not limited to beverage server 10 or beverages, can be collected from each store, it is possible to compare serving quality between stores.

[0143] Furthermore, in this embodiment, the beverage serving quality monitoring system 1 includes a beverage server sensor 20, a sensor unit 40 that measures the beverage before it is dispensed, and a sensor unit 60 that measures the beverage after it is dispensed. Each of the beverage server sensor 20, the sensor unit 40, and the sensor unit 60 is composed of multiple sensors. Therefore, it is possible to measure the beverage and the beverage server 10 with high accuracy at each process up to the provision of the beverage to the customer.

[0144] The above describes the embodiments of the beverage serving quality monitoring system and the beverage serving quality monitoring method according to the present disclosure. However, the present invention is not limited to the above-described embodiments, and may be modified or applied to other things within the scope of the gist described in the claims. In other words, the present invention can be modified in various ways within the scope of the gist described in the claims, and the configuration, function, shape, size, number, material, and arrangement of each part of the beverage serving quality monitoring system, as well as the content and order of each step of the beverage serving quality monitoring method, can be appropriately changed within the scope of the gist described above.

[0145] For example, in the above embodiment, the beverage server sensor 20 is described, which includes the water tank temperature sensor 21, the ice amount measurement sensor 22, the server power supply current sensor 23, the earth leakage breaker operation sensor 24, the stirring motor rotation speed sensor 25, the beverage line attachment sensor 26, the water tank water level sensor 27, the pedestal water volume sensor 28, the fan motor current measurement sensor 29, the outer surface condensation sensor 30, the water tank water quality sensor 31, the refrigeration device current measurement sensor 32, the pour lever open / close sensor 33, the faucet outlet temperature sensor 34, and the communication unit 35. However, the beverage server sensor may be a sensor in which at least some of the above sensors are omitted, and the sensor configuration of the beverage server sensor can be changed as appropriate. The same applies to the sensor unit 40 and the sensor unit 60.

[0146] In the above embodiment, an example has been described in which at least one of the sensor unit 40 and the sensor unit 60 is detachable from the beverage server 10. However, the sensor unit may be non-detachable from the beverage server 10, or may be provided integrally with the beverage server 10.

[0147] In the above embodiment, an example was described in which the beverage is a sparkling beverage B, and the sparkling beverage B is beer. However, the beverage serving quality monitoring system and beverage serving quality monitoring method according to the present disclosure can also be applied to sparkling beverages other than beer and beverages other than sparkling beverages. As a specific example, the beverage may be a sparkling beer with foam retention properties, a non-alcoholic beer, a chuhai, a sour, a highball, an RTD (Ready To Drink), a cola, a soda, a cider, or the like.
