[0043] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. The present disclosure is not limited to the following embodiments and can be modified in various ways without departing from the main purpose of the present disclosure. In addition, the present disclosure includes all combinations of structures that can be combined among the structures shown in the following embodiments. In addition, in the various figures, parts marked with the same figure mark are the same parts or equivalent parts, which are common to the entire text of the specification.

[0044] <Implementation Method 1>

[0045] Hereinafter, a first embodiment of the present disclosure will be described. The food hygiene management system according to the first embodiment is a system for managing the hygiene status of food in, for example, a food production factory that produces food.

[0046] [Structure of Food Sanitation Management System 100]

[0047] Figure 1 This is a schematic diagram illustrating an example of the structure of a food hygiene management system 100 according to Embodiment 1. Assume that food hygiene management system 100 performs food hygiene management processing on food 200, which is a target for management, while the food 200 is placed on a loading unit 300. Food 200 may be, for example, cooked food, refrigerated food, or frozen food. For example, a worker at a food manufacturing factory may transfer cooked food 200 to loading unit 300.

[0048] like Figure 1 As shown, the food hygiene management system 100 includes a food hygiene management device 10, a core temperature information generating device 20, a photographing device 30, a display device 40, an input device 50, and a server device 60. Furthermore, in the food hygiene management system 100, the food hygiene management device 10 and the server device 60 are interconnected via a network 400 such as the Internet or an intranet.

[0049] The food hygiene management device 10 performs overall control of various components included in the food hygiene management system 100. In the first embodiment, the food hygiene management device 10 executes a food hygiene management process for managing the hygiene status of the food 200. The food hygiene management process will be described in detail later.

[0050] The core temperature information generating device 20 measures the core temperature of the food 200. The core temperature information generating device 20 is, for example, a portable core thermometer. The core temperature refers to the central temperature of the food 200. The core temperature information generating device 20 includes a measurement input device 21 and a probe 22.

[0051] The measurement input device 21 receives an operation to start measuring the core temperature. The measurement input device 21 may be, for example, a switch. The probe 22 is inserted into the interior of the food 200. A sensor for measuring the core temperature of the food 200 is provided at the tip of the probe 22.

[0052] The operator inserts probe 22 of core temperature information generating device 20 into food 200 so that the tip of probe 22 is located inside the food and operates measurement input device 21. This allows core temperature information generating device 20 to measure the core temperature of food 200.

[0053] Core temperature information generating device 20 transmits core temperature information indicating the measured core temperature to food hygiene management device 10 via wireless communication or wired communication. Core temperature information generating device 20 also transmits date and time information indicating the date and time when the core temperature of food 200 was measured, along with the core temperature information, to food hygiene management device 10.

[0054] The photographing device 30 is a camera that captures still or moving images. Based on instruction information received from the food hygiene management device 10, the photographing device 30 photographs the food 200 and generates photographic data. The instruction information is information that instructs the photographing device 30 on its operation from the food hygiene management device 10.

[0055] Furthermore, as will be described later, the above-mentioned instruction information is transmitted from the food hygiene management device 10 to the photographing device 30 upon receipt of the core temperature information and date and time information transmitted from the core temperature information generating device 20. In other words, upon receipt of the core temperature information and date and time information from the core temperature information generating device 20 by the food hygiene management device 10, the photographing device 30 generates photographic data.

[0056] The photographing device 30 also generates a standby image, which is an image of the food 200 while the photographing is on standby (hereinafter referred to as "photographing standby" as appropriate). Instruction information at this time is transmitted from the food hygiene management device 10 to the photographing device 30 upon the start of the food hygiene management process.

[0057] The photographing device 30 transmits the generated photographic data and the standby image to the food hygiene management device 10 via wireless communication or wired communication.

[0058] The display device 40 displays information generated by the food hygiene management device 10. The display information is used to display a predetermined screen generated by the food hygiene management device 10 on the display device 40. The display device 40 is, for example, a display device such as a liquid crystal display or an organic EL (Electro Luminescence) display.

[0059] The input device 50 receives input operations to the food hygiene management device 10 and transmits operation information indicating the content of the operation to the food hygiene management device 10. The input device 50 is, for example, an operation input device such as a keyboard, a mouse, a trackball, or a touch panel. If the input device 50 is a touch panel, the input device 50 and the display device 40 may be arranged to overlap.

[0060] The server device 60 receives various data related to the food 200 from the food hygiene management device 10 via the network 400 and stores the received data.

[0061] The above describes the overall structure of the food hygiene management system 100. Figure 1 In the illustrated example, the food hygiene management device 10, core temperature information generating device 20, image capturing device 30, display device 40, and input device 50 are each independently configured. However, the present invention is not limited thereto, and at least some of the various components included in the food hygiene management system of the present disclosure may be combined.

[0062] For example, the display device 40 and the input device 50 may overlap to form a single touch panel. Alternatively, the camera device 30, the display device 40, and the input device 50 may be configured as a single computer (a personal computer (PC), a tablet terminal, a smartphone, etc.). Furthermore, for example, the functions of the food hygiene management device 10 may be realized by a computer including the camera device 30, the display device 40, and the input device 50. In this case, the core temperature information generation device 20 may be included as part of the computer.

[0063] Specifically, for example, one tablet terminal may include a photo shooting device 30 , a display device 40 such as a liquid crystal display, an input device 50 such as a touch panel, and a computer that realizes the functions of the food hygiene management device 10 .

[0064] [Hardware Structure of Food Sanitation Management Device 10]

[0065] A computer as an example of the hardware configuration of the food hygiene management device 10 will be described. Figure 2 Yes Figure 1A block diagram of an example of the hardware structure of the food hygiene management device 10. Figure 2 As shown, a computer 1000, which is an example of the hardware structure of the food hygiene management device 10, includes an input device 1001 such as a keyboard, mouse, or touchpad, an output device 1002 such as a display or speaker, a CPU (Central Processing Unit) 1003, a ROM (Read Only Memory) 1004, a RAM (Random Access Memory) 1005, a storage device 1006 such as a hard disk drive or an SSD (Solid State Drive), a reader 1007 for reading information from a recording medium such as a DVD-ROM (Digital Versatile Disk ROM) or a USB (Universal Serial Bus) memory, and a transceiver 1008 for communicating via a network. The various components of the computer 1000 are connected by a bus 1009.

[0066] The reading device 1007 reads a program for realizing the functions of each of the above-mentioned devices from a recording medium on which the program is recorded, and stores the program in the storage device 1006. Alternatively, the transceiver 1008 communicates with a system device connected to the network and stores the program for realizing the functions of each of the above-mentioned devices downloaded from the system device in the storage device 1006.

[0067] Then, the CPU 1003 copies the program stored in the storage device 1006 to the RAM 1005 , sequentially reads out and executes the instructions included in the program from the RAM 1005 , thereby realizing the various functions of the food hygiene management device 10 .

[0068] [Structure of Food Hygiene Management Device 10]

[0069] Figure 3 Yes Figure 1 Functional block diagram of an example of the structure of the food hygiene management device 10. Figure 3 As shown, the food hygiene management device 10 includes a core temperature acquisition unit 11, a photo acquisition unit 12, an operation information acquisition unit 13, a shooting instruction unit 14, a screen generation unit 15, a display information generation unit 16, a reading unit 17, a storage unit 18, a communication unit 19 and a judgment unit 110.

[0070] The core temperature acquisition unit 11 acquires the core temperature information and date and time information from the core temperature information generation device 20. The core temperature acquisition unit 11 supplies the acquired core temperature information and date and time information to the screen generation unit 15.

[0071] The photograph acquisition unit 12 acquires photograph data from the photograph shooting device 30. The photograph acquisition unit 12 supplies the acquired photograph data to the screen generation unit 15.

[0072] The operation information acquisition unit 13 acquires operation information from the input device 50 .

[0073] The photographing instruction unit 14 generates instruction information for instructing the photographing device 30 to operate. For example, when the food hygiene management process begins, the photographing instruction unit 14 transmits instruction information to the photographing device 30 for capturing an image during standby. For example, upon receipt of core temperature information and date and time information by the core temperature acquisition unit 11, the photographing instruction unit 14 transmits instruction information to the photographing device 30 for capturing an image of the food 200.

[0074] The screen generation unit 15 generates various screens for display on the display device 40. For example, the screen generation unit 15 generates a standby image display screen, which is a screen in which photography is on standby. Furthermore, for example, the screen generation unit 15 generates composite photo data by combining the type of food 200, its core temperature, the date and time of measurement, and the acceptable range for the core temperature with the photo data acquired by the photo acquisition unit 12. The screen generation unit 15 then generates a composite photo display screen for displaying the generated composite photo data. Details of the standby image display screen and the composite photo display screen will be described later.

[0075] The display information generating unit 16 generates display information for displaying the screen generated by the screen generating unit 15 on the display device 40 .

[0076] The reading unit 17 reads the food information image reflected in the standby image obtained during the shooting standby state and recognizes the food information based on the read food information image. The food information is information related to the food 200 being photographed, and indicates, for example, the type of food 200 or the acceptable range of the core temperature of the food 200.

[0077] The food information image is an image containing food information and is provided within the imaging range of the image capturing device 30, that is, on the upper surface of the loading portion 300. The food information image may be, for example, a text image representing information related to the food 200 in text, or a code image composed of a two-dimensional code such as a QR (Quick Response) code (registered trademark) or a one-dimensional code such as a barcode.

[0078] The storage unit 18 stores various information used by the food hygiene management device 10. For example, the storage unit 18 pre-stores an initial acceptable range value for the imaged object. The initial acceptable range value is the initial value of the acceptable range, which is a reference range for determining whether the core temperature of the food 200 is an appropriate temperature.

[0079] Furthermore, for example, the storage unit 18 stores the composite photograph data generated by the screen generation unit 15. When storing the composite photograph data, the storage unit 18 stores the composite photograph data in a table format that associates date and time information with the composite photograph data. Furthermore, the storage unit 18 stores the composite photograph data in the form of binary data. For example, a storage medium such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) is used as the storage unit 18.

[0080] In this example, the composite photo data and the initial value of the acceptable range are stored in the storage unit 18. However, the present invention is not limited thereto. For example, the composite photo data and the initial value of the acceptable range may also be stored in the server device 60. In this case, the composite photo data is transmitted to the server device 60 via the communication unit 19 and the network 400. Furthermore, the food hygiene management device 10 stores a URL (Uniform Resource Locator) indicating the address of the composite photo data stored in the server device 60 in the storage unit 18, instead of binary data.

[0081] In this example, the food hygiene management device 10 is shown as including the storage unit 18 as a storage device. However, the present invention is not limited thereto. For example, the food hygiene management device 10 may not include the storage unit 18. In this case, the food hygiene management device 10 may transmit the composite photo data to the server device 60 via the network 400, and the server device 60 may store the composite photo data.

[0082] The communication unit 19 is connected to the network 400 by wireless communication or wired communication, and controls communication with the server device 60. For example, the communication unit 19 transmits the composite photograph data generated by the screen generation unit 15 to the server device 60 via the network 400.

[0083] Determination unit 110 determines whether the core temperature of food 200 is within the acceptable range based on the core temperature information acquired by core temperature acquisition unit 11 and the acceptable range read by reading unit 17. Determination unit 110 then notifies screen generation unit 15 of the result of the determination as to whether the core temperature is within the acceptable range.

[0084] [Display of the Display Device 40]

[0085] The display on the display device 40 will be described. In this first embodiment, the display device 40 displays a standby image display screen or a composite photo display screen in accordance with the operation of the food hygiene management system 100. The standby image display screen is displayed on the display device 40 during the standby period until the food hygiene management process starts and photo data is generated by the photo capture device 30. The composite photo display screen displays the composite photo data generated by the photo capture device 30.

[0086] (Image display screen 1400 during standby)

[0087] Figure 4 and Figure 5 It means in Figure 1 FIG. 1 is a diagram showing an example of a standby image display screen 1400 displayed on the display device 40. The standby image display screen 1400 is a screen that displays the standby image generated by the photo shooting device 30 and information related to the photographed food 200 during the shooting standby. Figure 4 and Figure 5 As shown, the standby image display screen 1400 includes a captured image display area 1401 and a food information display area 1402 .

[0088] The captured image display area 1401 is used to display the standby image captured by the camera 30 during the standby state. The food information display area 1402 is used to display food information identified by reading a food information image 1403 that appears in the standby image. The food information image 1403 is an image that presents information related to the food 200 and includes, for example, at least one of a text image 1403a and a code image 1403b.

[0089] The text image 1403a presents information related to the food 200 in text. In the first embodiment, the text image 1403a mainly presents information related to the type of the food 200. Specifically, the text image 1403a presents the name or type of the food 200, such as "fried food," in text as the type of the food 200.

[0090] Furthermore, the text image 1403a is not limited thereto; the text image 1403a may also represent the acceptable range for the core temperature of the food 200 using text. For example, the text image 1403a may represent the acceptable range in a predetermined format. Thus, when the reading unit 17 reads the text image 1403a, the food hygiene management device 10 can recognize that the read text represents the acceptable range for the core temperature.

[0091] Code image 1403b represents information related to food 200 in a coded form. In this first embodiment, code image 1403b primarily represents information related to the acceptable range for the core temperature of food 200. Specifically, code image 1403b encodes information representing the acceptable range in a prescribed format such as JSON (JavaScript Object Notation).

[0092] For example, assume that code image 1403b is a code image in which information is encoded in the JSON format as follows. In this case, the value of "temp-low" represents the lowest temperature in the acceptable range, and the value of "temp-high" represents the highest temperature in the acceptable range. Furthermore, "comment" represents a character string used for synthesis.

[0093] {

[0094] "temp-low":75,

[0095] "temp-high":null,

[0096] "comment":"Fried Food Batch #2",

[0097] }

[0098] Therefore, in this example, the acceptable range is shown as "75°C~", and the type of food 200 is shown as "fried food batch #2." In addition, the value "null" of "temp-high" indicates that no value is set.

[0099] In the state where the food information image 1403 is not read or cannot be recognized, Figure 4 As shown, in food information display area 1402, the type and qualified range of food 200 based on the pre-set qualified range initial value are displayed as the initial value of the food information. Specifically, for example, in food information display area 1402, "Food Name None" is displayed as the initial value of the type of food 200, and "Qualified Range: 75°C~" is displayed as the initial value of the qualified range.

[0100] If the food information image 1403 is read normally, Figure 5 As shown, in the food information display area 1402, the food information of the identified food 200 is displayed in text. For example, the type and qualified range of the food 200 are displayed in the food information display area 1402. Figure 5 In the example shown, "fried food batch #2" is displayed as the type of food 200, and "acceptable range: 75°C~" is displayed as the acceptable range of food 200.

[0101] (Composite photo display screen 1410)

[0102] Figure 6 It means in Figure 1 FIG. 1 is a schematic diagram of an example of a composite photo display screen 1410 displayed on the display device 40. Figure 6 As shown, the composite photo display screen 1410 includes a food image 1411 , a core temperature image 1412 , an acceptable range image 1413 , a food type image 1414 , a measurement date and time image 1415 , a reshooting acceptance image 1416 , and a sending acceptance image 1417 .

[0103] The food image 1411 is an image generated by the photographing device 30 by photographing the food 200. The core temperature image 1412 is an image generated based on the core temperature information and indicating the core temperature of the food 200 using text.

[0104] Acceptable range image 1413 is an image that uses text to indicate the acceptable range of the core temperature of food 200. Food type image 1414 is an image that uses text to indicate the type of photographed food 200. Measurement date and time image 1415 is an image that uses text to indicate the measurement date and time, generated based on date and time information.

[0105] For example, the screen generation unit 15 synthesizes the photo data including the food image 1411 with the core temperature image 1412 , the qualified range image 1413 , the food type image 1414 , and the measurement date and time image 1415 , thereby generating synthesized photo data displayed as a synthesized photo display screen 1410 .

[0106] The re-shooting acceptance image 1416 is an image for the operator to select via the input device 50 when the operator determines that re-shooting is necessary after viewing the composite photograph display screen 1410 displayed on the display device 40 .

[0107] For example, if a worker viewing composite photo display screen 1410 determines that a new photo of food 200 is needed because the photo is blurry or unclear, the worker selects re-photographing acceptance image 1416 via input device 50. In this case, the composite image data before the re-photographing may be discarded or stored in storage unit 18.

[0108] Transmission acceptance image 1417 is an image for the operator to select via input device 50 after viewing composite photo display screen 1410 displayed on display device 40 and determining that re-photographing of food 200 is unnecessary and that the core temperature of food 200 is within the acceptable range displayed in acceptable range image 1413. Furthermore, if the operator, while viewing composite photo display screen 1410, finds that the core temperature shown in core temperature image 1412 is not within the acceptable range, the operator determines that re-cooking of food 200 is necessary because the food 200 does not meet the required hygienic standards.

[0109] Let's use a specific example to illustrate. For example, assuming food 200 is fried food, and the acceptable core temperature range for fried food is 75°C or higher, then if the core temperature shown in core temperature image 1412 is 72°C, the worker determines that food 200 should be re-cooked. Alternatively, assuming food 200 is frozen tuna, and the acceptable core temperature range for frozen tuna is -20°C or lower, then if the core temperature shown in core temperature image 1412 is -18°C, the worker determines that food 200 should be re-cooked or re-processed. If re-cooking or re-processing is determined to be necessary, the worker selects the operation to re-capture acceptance image 1416 via input device 50.

[0110] Then, if the worker determines that the food 200 should be cooked again, the worker may, for example, return the food 200 to the cooking process and cook it again. Alternatively, the worker may entrust another worker with the task of cooking the food 200 again.

[0111] Furthermore, if the operator determines that re-photographing of food 200 is unnecessary and that the core temperature of food 200 is within the acceptable range, the operator selects transmission acceptance image 1417 via input device 50. In response, input device 50 generates operation information indicating that transmission acceptance image 1417 has been selected and transmits the information to food hygiene management device 10.

[0112] [Operation of the Food Sanitation Management System 100]

[0113] Next, the operation of the food hygiene management system 100 according to the first embodiment will be described. Figure 7 and Figure 8 This is a sequence diagram showing an example of the flow of food hygiene management processing in the food hygiene management system 100 according to the first embodiment. Figure 7 and Figure 8 In FIG, marks A to E respectively indicate that the processing is transferred to the corresponding marks.

[0114] First, when the food hygiene management process starts, in step S1 , the food hygiene management device 10 sends instruction information for acquiring a standby image of an area including the placement portion 300 on which the food 200 serving as an imaging target is placed to the photographing device 30 .

[0115] In step S2 , the photographing device 30 acquires the standby image based on the received instruction information. In step S3 , the photographing device 30 transmits the acquired standby image to the food hygiene management device 10 .

[0116] In step S4, the food hygiene management device 10 reads the initial value of the acceptable range stored in the storage unit 18. In step S5, the food hygiene management device 10 generates a standby image display screen 1400 (see FIG. 1400 ) including the read initial value of the acceptable range and the standby image received from the photo shooting device 30. Figure 4 ).

[0117] In step S6, the food hygiene management device 10 transmits display information for displaying the standby image display screen 1400 to the display device 40. In step S7, the display device 40 displays the standby image display screen 1400 based on the display information received from the food hygiene management device 10. The processes of steps S1 to S3 are periodically repeated until the process of step S7 is completed.

[0118] The order of the processing of the food hygiene management device 10 acquiring the standby image described in steps S1 to S3 and the processing of acquiring the initial value of the acceptable range described in step S4 is not limited to this example. For example, the processing of step S4 may be performed before the processing of steps S1 to S3 or simultaneously with the processing of steps S1 to S3.

[0119] Furthermore, when the standby image display screen 1400 is already displayed on the display device 40, for example, a message prompting the user to read food information may be superimposed on the standby image display screen 1400 and displayed on the display device 40. Specifically, for example, a message such as "Please read food information" may be displayed on the standby image display screen 1400.

[0120] In step S8, when a food information image 1403 containing information related to the food 200 is shown in the standby image displayed on the standby image display screen 1400, the food hygiene management device 10 reads the food information image 1403. The food hygiene management device 10 then identifies the food information from the read food information image 1403. In step S9, the food hygiene management device 10 transmits display information to the display device 40 for adding the identified food information to the standby image display screen 1400.

[0121] In step S10, the display device 40 displays the food information in the food information display area 1402 of the standby image display screen 1400 based on the display information received from the food hygiene management device 10, thereby updating the standby image display screen 1400. At this point, the display device 40 may also display a message prompting the user to measure the core temperature of the food 200, for example, superimposed on the standby image display screen 1400. Specifically, a message such as "Please measure the core temperature" may be displayed on the standby image display screen 1400.

[0122] On the other hand, in step S11, the probe 22 is inserted into the food 200 placed on the placement portion 300 (see Figure 1 ), the operator presses the measurement input device 21 of the core temperature information generating device 20. In step S12, the core temperature information generating device 20 measures the core temperature of the food 200 and generates core temperature information and date and time information indicating the date and time of the measurement.

[0123] In step S13, the core temperature information generating device 20 transmits the generated core temperature information and date and time information to the food hygiene management device 10. In step S14, the food hygiene management device 10, having received the core temperature information and date and time information, transmits instruction information to the photographing device 30, instructing the photographing device 30 to take a photo of the food 200.

[0124] In step S15, the photographing device 30 photographs the food 200 based on the received instruction information and generates photographic data. In step S16, the photographing device 30 transmits the generated photographic data to the food hygiene management device 10. In step S17, the food hygiene management device 10 determines whether the core temperature indicated by the core temperature information is within the acceptable range based on the acceptable range and the core temperature information.

[0125] In step S18, the food hygiene management device 10 that has received the photo data generates composite photo data based on the core temperature information, date and time information, and the photo data. Furthermore, the food hygiene management device 10 generates a composite photo display screen 1410 (see FIG. 141 ) based on the generated composite photo data. Figure 6 ).

[0126] Here, if it is determined in step S17 that the core temperature is within the acceptable range, the food hygiene management device 10 may add a display indicating that the core temperature meets the criteria to the composite photo display screen 1410, in addition to the core temperature information and date and time information. Alternatively, if it is determined that the core temperature is not within the acceptable range, the food hygiene management device 10 may add a display indicating that the core temperature does not meet the criteria to the composite photo display screen 1410, in addition to the core temperature information and date and time information.

[0127] In this way, when the composite photograph display screen 1410 with the additional indication that the core temperature of the food 200 does not meet the reference is transmitted to the display device 40 and displayed, the worker can clearly understand that the core temperature of the food does not meet the reference.

[0128] In step S19, the food hygiene management device 10 transmits display information for displaying the generated composite photo display screen 1410 to the display device 40. In step S20, the display device 40 displays the composite photo display screen 1410 based on the display information received from the food hygiene management device 10.

[0129] In step S21, the input device 50 receives an operation to transmit composite photo data from an operator viewing the composite photo display screen 1410, and based on the operator's operation, generates operation information for transmitting the composite photo data to the server device 60. In step S22, the input device 50 transmits the generated operation information to the food hygiene management device 10.

[0130] The food hygiene management device 10, which has received the operation information for transmitting the composite photo data, transmits the composite photo data to the server device 60. The server device 60 stores the received composite photo data. In this way, the food hygiene management process for one food 200 is completed.

[0131] Then, the operator carries the food 200 that has completed the food hygiene management process to the next process, such as the packaging process or the shipping process, and places the new food 200 on the placing portion 300 (see Figure 1 Then, the process returns to step S1.

[0132] In addition, Figure 8In the timing diagram, after the operator observes the composite photo data in the composite photo display screen 1410 displayed on the display device 40 in step S20, he determines that it is necessary to retake the photo and retakes the acceptance image 1416 (refer to Figure 6 ) is operated, the input device 50 generates operation information indicating that the re-photographing acceptance image 1416 has been operated and sends it to the food hygiene management device 10.

[0133] In response, the food hygiene management device 10 again transmits instruction information for photographing to the photographing device 30, instructing it to take another photograph. The food hygiene management device 10 then generates new composite photograph data based on the photographic data obtained from the retake, and creates a composite photograph display screen 1410 based on the new composite photograph data. The new composite photograph display screen 1410 is transmitted to the display device 40 and displayed. This process is repeated until the operator operates the transmission acceptance image 1417.

[0134] exist Figure 7 and Figure 8 In the illustrated example, the core temperature information generating device 20 generates and transmits the core temperature measurement date and time information along with the core temperature information to the food hygiene management device 10. However, the present disclosure is not limited to this. For example, the core temperature information generating device 20 may not generate the date and time information, and the food hygiene management device 10, upon receiving the core temperature information from the core temperature information generating device 20, may generate the date and time information based on the time the core temperature information was received. Furthermore, the date and time information may be generated appropriately by a component other than the core temperature information generating device 20 or the food hygiene management device 10, such as the image capture device 30, the display device 40, or the input device 50.

[0135] The core temperature acceptance determination performed in step S17 may also be performed, for example, in the server device 60. In this case, the food hygiene management device 10 transmits the acceptance range included in the food information identified in step S8 and the core temperature information received in step S13 to the server device 60. Based on the received acceptance range and the core temperature information, the server device 60 determines whether the core temperature indicated by the core temperature information is within the acceptance range, and transmits information indicating the determination result to the food hygiene management device 10.

[0136] In addition, in this example, the case where the generated composite photo data is sent to the server device 60 and stored is described, but it is not limited to this. For example, the composite photo data may also be stored in the food hygiene management device 10. In this case, when the food hygiene management device 10 Figure 8Upon receiving the operation information in step S22 , the food hygiene management device 10 stores the composite photograph data in the storage unit 18 .

[0137] Figure 9 This is a flowchart showing an example of the flow of food hygiene management processing performed by the food hygiene management system 100 according to the first embodiment. Figure 9 The operation of the food hygiene management device 10 when performing food hygiene management processing is shown.

[0138] In step S31, the food hygiene management device 10 reads and sets the initial value of the acceptable range from the storage unit 18. As a result, the initial value is displayed in the food information display area 1402 of the standby image display screen 1400.

[0139] In step S32, the determination unit 110 of the food hygiene management device 10 determines whether the food information image 1403 is displayed in the captured image display area 1401 of the standby image display screen 1400. In this case, the reading unit 17 of the food hygiene management device 10 reads the food information image 1403. The determination unit 110 then determines whether the food information image 1403 is displayed in the captured image display area 1401 based on whether the reading unit 17 has recognized the food information.

[0140] If it is determined that the food information image 1403 is displayed in the captured image display area 1401 (step S32: Yes), the process proceeds to step S33. On the other hand, if it is determined that the food information image 1403 is not displayed in the captured image display area 1401 (step S32: No), the process proceeds to step S36. In other words, if the food information image 1403 is not displayed in the captured image display area 1401 or the food information image 1403 cannot be read, the food hygiene management device 10 proceeds with the food hygiene management process without reading the food information.

[0141] In step S33, the determination unit 110 determines whether the food information recognized by the reading unit 17 includes setting information regarding the acceptable range. In this example, it is assumed that the food information read by the reading unit 17 includes information indicating the type of the food 200.

[0142] If the food information is determined to include setting information regarding an acceptable range (step S33: Yes), the food hygiene management device 10 sets the type of food 200 and the acceptable range for the core temperature in step S34. On the other hand, if the food information is determined to include only information regarding the type of food 200, but does not include setting information regarding an acceptable range (step S33: No), the food hygiene management device 10 sets the type of food 200 in step S35.

[0143] Here, the type and acceptable range of food 200 are set separately, and only the newly recognized information is updated in the settings. For example, if the recognized food information only includes the acceptable range of food 200, only the information indicating the acceptable range is updated, while the information indicating the type of food 200 remains the same as it was before.

[0144] In step S36, the food hygiene management device 10 determines whether the core temperature acquisition unit 11 has acquired the core temperature of the food 200. If it is determined that the core temperature has been acquired (step S36: Yes), the screen generation unit 15 of the food hygiene management device 10 generates composite photo data in step S37 and displays the composite photo display screen 1410. If it is determined that the core temperature has not been acquired (step S36: No), the process returns to step S32.

[0145] In step S38, the food hygiene management device 10 determines whether the worker has pressed the transmission acceptance icon 1407 on the composite photo display screen 1410. If it is determined that the transmission acceptance icon 1407 has been pressed (step S38: Yes), the food hygiene management device 10 transmits the composite photo data to the server device 60 via the communication unit 19 in step S39. On the other hand, if it is determined that the transmission acceptance icon 1407 has not been pressed (step S38: No), the process returns to step S32.

[0146] In this example, even when food information related to the food 200 is not obtained, the food hygiene management process is performed and past information such as the initial value of the qualified range is used. However, this is not limited to this. For example, obtaining food information may be required.

[0147] Figure 10 This is a flowchart showing another example of the flow of the food hygiene management process in the food hygiene management system 100 according to the first embodiment. Figure 10 1 and 2 show the operation of the food hygiene management device 10 when performing food hygiene management processing. Figure 10 The example shown shows the process flow when it is necessary to read the food information image 1403. Figure 10In the description of Figure 9 The same processing is denoted by the same reference numerals and description thereof is omitted.

[0148] When the food hygiene management device 10 determines in step S36 that the core temperature acquisition unit 11 has acquired the core temperature of the food 200 (step S36 : Yes), the process proceeds to step S41 .

[0149] In step S41, the food hygiene management device 10 determines whether the food information image 1403 reflected in the captured image display area 1401 has been read by the reading unit 17. If it is determined that the food information image 1403 has been read (step S41: Yes), the screen generation unit 15 generates composite photo data in step S37 and generates a composite photo display screen 1410.

[0150] On the other hand, if it is determined that the food information image 1403 has not been read (step S41: No), the screen generation unit 15 generates a message in step S42 prompting the user to read the food information image 1403. The display information generation unit 16 then generates display information for causing the display device 40 to display the generated message. The process then returns to step S32.

[0151] (Variation)

[0152] Next, a modification of the food hygiene management process of the first embodiment will be described. Figure 9 and Figure 10 In the illustrated example, a case where at least one food information image 1403 including the type of food 200 is read is described, but the present invention is not limited thereto. For example, a plurality of food information images 1403 may be read.

[0153] Specifically, for example, there may be multiple food information images 1403 being read, one of which contains the type of food 200 and another contains the acceptable range for core temperature, and each of the multiple food information images 1403 contains different food information. In this case, the food hygiene management device 10 reads the multiple food information images 1403 simultaneously or sequentially and updates the food information based on the read results.

[0154] Figure 11 This is a flowchart showing a modified example of the flow of the food hygiene management process in the food hygiene management system 100 according to the first embodiment. Figure 11 The operation of the food hygiene management device 10 during food hygiene management is shown below. Figure 11 In the description of Figure 9 The same processing is denoted by the same reference numerals and description thereof is omitted.

[0155] If it is determined in step S32 that the food information image 1403 is displayed in the captured image display area 1401 (step S32: Yes), the process proceeds to step S43. In step S43, the determination unit 110 of the food hygiene management device 10 determines whether the food information recognized by the reading unit 17 includes setting information regarding the type of the food 200.

[0156] If it is determined that the food information includes setting information regarding the type of food 200 (step S43: Yes), the food hygiene management device 10 sets the type of food 200 in step S44. If it is determined that the food information does not include setting information regarding the type of food 200 (step S43: No), the process proceeds to step S33.

[0157] In step S33, the determination unit 110 determines whether the food information recognized by the reading unit 17 includes setting information regarding an acceptable range. If the food information is determined to include setting information regarding an acceptable range (step S33: Yes), the food hygiene management device 10 sets an acceptable range for the core temperature of the food 200 in step S45. On the other hand, if the food information is determined not to include setting information regarding an acceptable range (step S33: No), the process proceeds to step S36.

[0158] Afterwards, with Figure 9 Similarly to the example shown, the food hygiene management device 10 generates composite photo data and a composite photo display screen 1410 based on the received core temperature of the food 200. Then, when the worker presses the transmission acceptance icon 1407 on the composite photo display screen 1410, the food hygiene management device 10 transmits the generated composite photo data to the server device 60.

[0159] Alternatively, the food hygiene management device 10 may read the type and qualified range of the food 200 and then reread the food information image 1403 containing information about a certain food, and update the food information. Figure 11 In the example shown, the processing of steps S32 to S45 is repeated until the core temperature of the food 200 is measured in step S36. Thus, the food information image 1403 is repeatedly read, and thus the food information can be corrected.

[0160] Figure 12 This is a schematic diagram showing an example of a code image 1403b. This code image 1403b is an example of a food information image 1403 for setting an acceptable range for the core temperature of the food 200. It is a QR code describing information indicating that the minimum temperature of the acceptable range is "58°C" in a JSON format.

[0161] exist Figure 11 In the food hygiene management process shown, during the period until the core temperature of the food 200 is obtained in step S36, Figure 12 The food information image 1403, such as the code image 1403b shown, is read, and the food information, such as the acceptable range, is changed. In this case, the operator does not need to touch the input device 50 or the like of the food hygiene management system 100. Therefore, the acceptable range for the core temperature of the food 200 can be changed more hygienically.

[0162] The above-described example of the operation of the food hygiene management system 100 is merely an example, and different operations may be performed depending on the operation method set by the company that uses the food hygiene management system 100. Figure 7 and Figure 8 The timing diagram and Figure 9 and Figure 10 In the flowchart, when the operator operates the transmission acceptance image 1417, the food hygiene management device 10 transmits the composite photograph data. As another example of the operation, the food hygiene management device 10 may transmit the composite image data based on a trigger other than the operation of the transmission acceptance image 1417.

[0163] Let's use a specific example to illustrate. For example, the food hygiene management device 10 may further include a microphone and a voice recognition unit. When the microphone and voice recognition unit recognize a word such as "send" or "execute" uttered by the operator, the food hygiene management device 10 transmits the synthesized image data. Alternatively, the food hygiene management device 10 may further include a foot switch such as a pedal, and when the operator steps on the foot switch, the synthesized image data is transmitted. This configuration eliminates the need for the operator to touch the input device 50 of the food hygiene management system 100 during operation, thereby improving hygiene.

[0164] Alternatively, in some methods of operating the food hygiene management system 100, the composite image data may be transmitted regardless of whether the core temperature of the food 200 is within the acceptable range. In this case, for example, the food hygiene management system 10 automatically transmits the food image data after a predetermined time has elapsed since the composite image data was displayed on the display device 40. A message such as "Composite image data will be transmitted in 10 seconds" may be displayed on the screen displayed on the display device 40.

[0165] Furthermore, when transmitting composite image data of food whose core temperature does not fall within the acceptable range, the composite image data may be transmitted with a flag indicating that the core temperature does not fall within the acceptable range attached. In this case, hygienic management can be performed by measuring the core temperature of food 200, and information regarding the time period when the core temperature did not meet the reference standard can be stored.

[0166] Alternatively, if the core temperature of the food 200 is outside the acceptable range, the synthesized image data may not be transmitted. In this case, for example, the food hygiene management device 10 may display a warning message on the display device 40 for a predetermined time, indicating that the measured core temperature of the food 200 is outside the acceptable range, and may not transmit the synthesized image data. The food hygiene management device 10 may then return the system to the shooting standby state, displaying the standby image display screen 1400 on the display device 40.

[0167] As described above, the food hygiene management device 10 of this embodiment 1 generates a composite photo display screen 1410, and the composite photo display screen 1410 displays composite photo data, which includes the core temperature information obtained by the core temperature acquisition unit 11, the date and time information of the core temperature measurement, the qualified range included in the food information image recognized by the reading unit 17, and the photo data of the food 200 obtained by the photo acquisition unit 12.

[0168] In this manner, in the food hygiene management device 10, the acceptable range for the core temperature of the food 200 is identified by reading the food information image, eliminating the need for the operator to set an acceptable range for the core temperature. Consequently, the labor and time required for food hygiene management can be reduced, and hygiene management can be performed more hygienically.

[0169] <Implementation Method 2>

[0170] The following describes a second embodiment of the present disclosure. The acceptable range for the core temperature of food 200 is set based on the food information image read during the capture standby mode. However, even for the same type of food 200, the acceptable range for the core temperature may differ depending on the delivery destination of the food 200. Therefore, in this second embodiment, the set value for the acceptable range for the core temperature contained in the read food information image can be modified. Figure 13 1 is a schematic diagram showing an example of a food information change screen 1500 displayed on the display device 40 of the second embodiment. Figure 13 As shown, the food information change screen 1500 includes an acceptable range selection image 1501 , a numerical value selection image 1502 , a change completion image 1503 , and a change cancel image 1504 .

[0171] Acceptable range selection image 1501 displays the upper and lower limits of the acceptable range for the core temperature of food 200, set based on food information. Acceptable range selection image 1501 allows the operator to select the upper or lower limit of the acceptable range via input device 50 when determining that the set value of the acceptable range should be changed. In acceptable range selection image 1501, for example, the background of the selected value changes. In this example, the background of the lower limit of the acceptable range is hatched, indicating that the lower limit has been selected.

[0172] Numerical selection image 1502 is, for example, a numeric key image, and is composed of a plurality of key images including numerical values ​​from 0 to 9, for changing the upper limit value or lower limit value displayed in acceptable range selection image 1501. If the operator determines that the acceptable range setting value should be changed, the operator uses numerical selection image 1502 via input device 50 to input the acceptable range setting value.

[0173] The change completion image 1503 is an image for completing the change of the setting value of the acceptable range. When the operator determines that the change of the setting value of the acceptable range is completed, the operator selects the change completion image 1503 via the input device 50.

[0174] The change cancel image 1504 is an image for canceling the change of the setting value of the acceptable range made using the numerical selection image 1502. When the operator determines that the change of the setting value of the acceptable range should be canceled, he selects the change cancel image 1504 via the input device 50.

[0175] Such a food information change screen 1500 is obtained by changing the standby image display screen 1400 (see FIG. Figure 8 For example, a qualified range change image (not shown) is displayed on the standby image display screen 1400, and when the operator selects the qualified range change image, the food information change screen 1500 is displayed.

[0176] Figure 14 This is a flowchart showing an example of the flow of food hygiene management processing performed by the food hygiene management system 100 according to the second embodiment. Figure 14 The operation of the food hygiene management device 10 during food hygiene management is shown below. Figure 14 In the description of Figure 9 The same processing is denoted by the same reference numerals and description thereof is omitted.

[0177] In the food hygiene management process of this embodiment 2, if the food information about the food 200 is set (step S32: No, step S34 or step S35), in step S51, the food hygiene management device 10 determines whether the food information change screen 1500 is displayed on the display device 40 and the qualified range for the food 200 is changed.

[0178] If the acceptable range is determined to have been changed (step S51: Yes), the food hygiene management device 10 changes the acceptable range setting for the core temperature of the food 200 to the value changed on the food information change screen 1500 in step S52. The process then proceeds to step S36. If the acceptable range is determined not to have been changed (step S51: No), the process proceeds to step S36 while maintaining the current acceptable range setting.

[0179] As described above, in this second embodiment, the operator can change the acceptable range displayed on the food information change screen 1500. Therefore, even if the acceptable range for the core temperature of the food 200 differs depending on the delivery destination, etc., it can be easily handled.

[0180] Furthermore, while this example illustrates the ability to change the acceptable range for core temperature by operating the numerical selection icon 1502 on the food information change screen 1500, the system is not limited thereto and can also change the acceptable range by performing other operations. For example, the food hygiene management system 10 can be equipped with a microphone and a voice recognition unit to change the acceptable range for core temperature based on the operator's voice. This configuration eliminates the need for the operator to touch the input device 50 or the like of the food hygiene management system 100 during operation, thereby improving hygiene.

[0181] In this example, the case where the setting of the acceptable range for the core temperature is changed by operating the food information change screen 1500 is described, but the present invention is not limited thereto. For example, the setting regarding the type of food 200 may be changed.

[0182] While the first and second embodiments have been described above, the present disclosure is not limited to these embodiments and various modifications and applications are possible without departing from the spirit of the present disclosure. For example, the initial acceptable range values ​​used in food hygiene management are not limited to being pre-stored in the storage unit 18 of the food hygiene management device 10. For example, the initial acceptable range values ​​may be pre-stored in the server device 60, and the food hygiene management device 10 may receive the initial acceptable range values ​​from the server device 60 when setting the initial acceptable range values.

[0183] Furthermore, while the code image 1403b of the food information image 1403 includes information regarding the type of food 200 and the acceptable range for the core temperature, the present invention is not limited thereto. Alternatively, each piece of information may be included in separate code images 1403b. Specifically, for example, a code image 1403b including information regarding the type of food 200 and a code image 1403b including information regarding the acceptable range for the core temperature may be prepared as the food information image 1403, and the reader 17 may read each code image 1403b separately.

[0184] In addition, a function of recognizing food information by reading the food information image 1403 during the shooting standby may be provided in an optional manner.

[0185] The disclosures of the specification, drawings, and abstract contained in Japanese patent application No. 2023-015505 filed on February 3, 2023 are incorporated herein by reference in their entirety.
