[0028] (Foundation, etc. that forms the basis of the present invention)

[0029] When the inventors finally came up with the present invention, there was a technology that performs shooting when an object passing through the opening of a cold storage is detected, and manages the food stored in the cold storage based on the shooting results. In the prior art, a camera device sends management data for managing items stored in the cold storage to an external device through wireless communication.

[0030] However, since the top surface of the main box of the cold storage is usually made of metal, interference caused by the top surface may occur in the radio waves received and sent by the wireless communication module depending on the positional relationship between the wireless communication module included in the camera device and the top surface of the main box. Therefore, the inventors found the following problem: depending on the positional relationship between the wireless communication module included in the camera device and the top surface of the main box, the wireless communication module cannot stably send management data, which can be said to reduce the management accuracy of the items. In order to solve this problem, the subject of the present invention is finally formed.

[0031] Therefore, the present invention provides an article management system and a refrigerator capable of suppressing a decrease in management accuracy of articles stored in a refrigerator.

[0053] The main box body 20 is a box-shaped component that forms the main body of the cold storage 2. The main box body 20 includes: an outer box 202 that is open on the front surface; an inner box 203 that is housed inside the outer box 202 and is open on the front surface; and a heat-insulating material that fills the space between the outer box 202 and the inner box 203. The outer box 202 is formed of, for example, a metal such as iron or a hard resin such as ABS. The upper surface of the outer box 202, that is, the top surface 20A of the main box 20, is formed of metal. The inner box 203 is formed of, for example, a hard resin such as ABS. The heat-insulating material is, for example, hard polyurethane foam. In addition, the heat-insulating material is not limited to this, and any material can be used as long as it has heat-insulating properties and can be filled in the space between the outer box 202 and the inner box 203.

[0054] The inner space of the inner box 203 is divided into a plurality of spaces by a partition member. In this embodiment, the inner space of the inner box 203 is divided into five spaces, which function as a refrigerating chamber 21, an ice making chamber 22, a fresh freezing chamber 23, a freezing chamber 24, and a vegetable chamber 25, respectively.

[0055] The right door 21B is rotatably supported by a right door hinge member 204, which is a hinge member provided on the top surface 20A of the main housing 20. The left door 21C is rotatably supported by a left door hinge member 205, which is a hinge member provided on the top surface 20A of the main housing 20.

The rotating partition 21D included in the left door 21C has a heater for preventing condensation, in which AC (Alternating Current) power is supplied from the main box 20 via the left door hinge part 205 as driving power. Therefore, in order to prevent the radio waves from being affected by the power supplied to the heater, the second wireless communication module 206 is provided on the right door hinge part 204 instead of on the left door hinge part 205.

[0058] [1-1-3. Configuration of the imaging device]

[0059] Reference Figure 3-Figure 7 The imaging device 3 will be described.

[0060] exist Figure 3-Figure 7 The diagram and Figure 2 The X-axis, Y-axis, and Z-axis shown are the same as the X-axis, Y-axis, and Z-axis. The X-axis direction corresponds to the width direction of the imaging device 3 and the left-right direction of the imaging device 3. The Y-axis direction corresponds to the front-back direction of the imaging device 3. The Z-axis direction corresponds to the up-down direction of the imaging device 3.

[0061] Figure 3 It is a top view of the imaging device 3 attached to the refrigerator 2 as seen from the right. Figure 4 This is a perspective view of the restriction member 34 in contact with the front end edge 20B of the main housing 20 as viewed from the left front.

The photographing member 31 is disposed on the upper front portion of the main body 30 .

[0063] The main body 30 includes a power button 32 on the front surface for turning on and off the power of the imaging device 3. The power button 32 is provided with a first LED (Light emitting diode) 33 for notifying predetermined information.

[0064] The main body 30 includes a limiting component 34. The limiting component 34 limits the position of the shooting component 31 in the front-to-back direction of the cold storage 2 by abutting against the front end edge 20B of the main body 20. The limiting component 34 is a sheet extending from the bottom surface 30A of the main body 30. The limiting component 34 extends along the width direction of the main body 30 (the width direction of the camera device 3) on the front surface of the main body 30, and has a mark 35 at the center of the width direction of the main body 30. The mark 35 indicates the center of the width direction of the camera device 3. The length of the limiting component 34 extending from the bottom surface 30A is formed to be shorter than the length from the top surface 20A of the main body 20 to the door gasket provided on the upper inner surface of the door 21A and substantially parallel to the top surface 20A.

[0065] Figure 5 It is a plan view of refrigerator 2 and imaging device 3 attached to refrigerator 2 as seen from the front. Figure 5 Door 21A of refrigerator 2 is shown in an open state. Figure 6 It is a top view of refrigerator 2 and imaging device 3 attached to refrigerator 2 as seen from the right. Figure 6 Drawer 25A of refrigerator 2 is shown in an open state, that is, in a pulled-out state. Figure 7 It is a top view of imaging device 3 attached to refrigerator 2 as seen from above.

[0066] The camera device 3 includes a wide-angle camera 301 and a narrow-angle camera 302. The wide-angle camera 301 and the narrow-angle camera 302 are disposed at the front end portion of the bottom surface 31A of the imaging member 31. When the camera device 3 is installed in the cold storage 2 and the door 21A is closed, the wide-angle camera 301 and the narrow-angle camera 302 are located in front of the door 21A.

[0067] Wide-angle camera 301 is a camera having a wider angle than narrow-angle camera 302. In a state where imaging device 3 is attached to refrigerator 2, wide-angle camera 301 captures refrigerating room 21 from the upper front of refrigerator 2.

[0068] For example, when viewed from the front of the cold storage 2, the shooting range of the wide-angle camera 301 includes Figure 5 The range A1 is a range including the door shelves 21E of the right door 21B and the left door 21C and the opening 201 of the refrigerator 21 when the right door 21B and the left door 21C are opened to the maximum degree. In addition, the shooting range of the wide-angle camera 301 includes Figure 6Range A3 is a range from the front end of the right door 21B and the left door 21C in the open state to the front end of the shelf 21F in the front-rear direction, and includes the opening 201 of the refrigerating chamber 21 in the up-down direction.

[0069] Narrow-angle camera 302 is a camera having a narrower angle than wide-angle camera 301. In a state where imaging device 3 is mounted on refrigerator 2, narrow-angle camera 302 captures an image of drawer 26A from the upper front of refrigerator 2.

[0070] For example, when viewed from the front of the cold storage 2, the shooting range of the narrow-angle camera 302 includes Figure 5 The range A2 shown. When viewed from the front of the refrigerator 2, the range A2 includes the drawer 26A. In addition, for example, when viewed from the right of the refrigerator 2, the shooting range of the narrow-angle camera 302 includes Figure 6 The range A4 is a range including the drawer 26A in the state of being pulled out first in the front-rear direction.

[0071] The imaging device 3 includes a first optical sensor 303 and a second optical sensor 304 . The first optical sensor 303 and the second optical sensor 304 are provided on the main body 30 .

[0072] The first optical sensor 303 is a sensor for detecting the opening and closing of the right door 21B. The first optical sensor 303 is a reflective optical sensor. The first optical sensor 303 projects light to a predetermined portion of the right door 21B when the imaging device 3 is mounted on the refrigerator 2. Then, the first optical sensor 303 outputs a signal indicating the amount of light received.

[0073] The second optical sensor 304 is a sensor for detecting the opening and closing of the left door 21C. The second optical sensor 304 is a reflective optical sensor. The second optical sensor 304 projects light to a predetermined portion of the left door 21C when the imaging device 3 is mounted on the refrigerator 2. Then, the second optical sensor 304 outputs a detection value indicating the amount of received light.

[0074] The imaging device 3 includes a thermopile 305. The thermopile 305 is a sensor for detecting the opening and closing of the drawer 26A. The thermopile 305 is provided at the front end of the bottom surface 31A of the imaging member 31. The thermopile 305 outputs a detection value indicating the detected temperature.

[0075] The imaging device 3 includes a human sensor 306. The human sensor 306 may be an infrared sensor or an ultrasonic sensor. The human sensor 306 outputs a detection value. The human sensor 306 is provided at the front end of the bottom surface 31A of the imaging member 31.

[0076] The imaging device 3 includes an illuminance sensor 307. The illuminance sensor 307 is a sensor for adjusting the exposure of the wide-angle camera 301 and the narrow-angle camera 302. The illuminance sensor 307 outputs a detection value. The illuminance sensor 307 is provided at the front end of the imaging unit 31.

[0077] The imaging device 3 includes a second LED 308 and a third LED 309. The second LED 308 is provided at the right front end of the bottom surface 31A of the imaging member 31. The third LED 309 is provided at the left front end of the bottom surface 31A of the imaging member 31. The second LED 308 and the third LED 309 illuminate the refrigerator 2 on which the imaging device 3 is mounted from above.

[0078] like Figure 7 As shown, the imaging device 3 includes a first control substrate 311 and a second control substrate 312 .

[0079] The first control substrate 311 is a substrate for controlling various sensors included in the camera device 3 and the power supply of the camera device 3. The first control substrate 311 is provided inside the camera device 3. The power button 32, the first LED 33, the first light sensor 303, the second light sensor 304, the thermocouple 305, the human sensor 306, and the illuminance sensor 307 are connected to the first control substrate 311. And the first control substrate 311 controls these devices. The first control substrate 311 is provided behind the second control substrate 312 and the first wireless communication module 313.

[0080] The second control substrate 312 is a substrate that controls the wide-angle camera 301 and the narrow-angle camera 302, and also controls the first wireless communication module 313. The second control substrate 312 is provided inside the camera device 3. The wide-angle camera 301, the narrow-angle camera 302, and the first wireless communication module 313 are connected to the second control substrate 312. And the second control substrate 312 controls these devices. The second control substrate 312 is provided side by side with the first control substrate 311 in front of the first control substrate 311.

[0081] The first wireless communication module 313 is a device including hardware such as an antenna or a wireless communication circuit. The first wireless communication module 313 is provided inside the imaging component 31, to the left of the second control substrate 312. The first wireless communication module 313 is provided in the imaging device 3 so as to be located in front of the opening 201 of the main body 20 when the imaging device 3 is installed in the cold storage 2. More specifically, the first wireless communication module 313 is provided in front of the limiting component 34 in the imaging device 3.

[0082] Assuming that the first wireless communication module 313 is disposed behind the limiting member 34, when the camera device 3 is installed in the cold storage 2, the first wireless communication module 313 is located at a position overlapping with the top surface 20A when viewed from above. Since the top surface 20A of the main body 20 is usually formed of metal, if the first wireless communication module 313 and the top surface 20A overlap when viewed from above, interference caused by the top surface 20A may occur in the radio waves received and sent by the first wireless communication module 313. However, in this embodiment, since the first wireless communication module 313 and the top surface 20A do not overlap when viewed from above, interference caused by the top surface 20A in the radio waves received and sent by the first wireless communication module 313 can be suppressed. In addition, in this embodiment, when viewed from above, the first wireless communication module 313 overlaps with the door 21A. However, the frame of the door 21A is usually made of resin. Therefore, the possibility of interference with the radio waves received and sent by the first wireless communication module 313 is low.

[0083] Furthermore, in a state where the camera device 3 is installed in the cold storage 2, the first wireless communication module 313 may also be arranged to be located above the top surface of the door 21A. For example, the first wireless communication module 313 may also be located above one side of the door 21A. In addition, for example, the first wireless communication module 313 may also be located above the top surface 20A of the cold storage 2. In addition, for example, the first wireless communication module 313 may also be located above the front of the door 21A in a closed state. Thus, assuming that the frame of the door 21A is formed of metal, interference in the radio waves of the first wireless communication module 313 can also be suppressed.

[0084] When the camera device 3 is installed in the main housing 20, the first wireless communication module 313 is located on the opposite side of the position where the second wireless communication module 206 is provided. Figure 7 As shown, when the camera 3 is installed in the cold storage 2, the first wireless communication module 313 is arranged on the left side of the center ST of the camera 3 in the left-right direction of the cold storage 2 (the left-right direction of the camera 3). That is, when the camera 3 is installed in the cold storage 2, the first wireless communication module 313 is arranged on the left side of the door hinge member 205 than the center ST of the camera 3. Thus, since the distance between the first wireless communication module 313 and the second wireless communication module 206 can be ensured, the interference of radio waves generated between the first wireless communication module 313 and the second wireless communication module 206 can be suppressed.

[0085] In addition, the position on the opposite side of the position where the second wireless communication module 206 is provided is not limited to the position in the left-right direction of the cold storage 2 with the center ST of the camera device 3 as the reference. The reference may also be a prescribed portion of the camera device 3. For example, the reference may be the right side surface of the camera device 3, or may be a substrate included in the camera device 3. In addition, the reference may also be a prescribed portion of the cold storage 2.

[0086] The camera device 3 includes a metal portion 314. The metal portion 314 is provided on the opposite side of the position where the first wireless communication module 313 is provided when the camera device 3 is installed in the main housing 20. Figure 7 As shown, in a state where the camera device 3 is installed in the cold storage 2, a metal plate 314 is provided between the first wireless communication module 313 and the second wireless communication module 206 in the left-right direction. The metal plate 314 may also be provided to cover the entire area of ​​the right inner side surface 315 of the shooting component 31. In addition, the metal plate 314 may also be provided on the right inner side surface 315 of the shooting component 31 in a range including the first wireless communication module 313 when viewed from the side. In addition, the metal plate 314 may also be provided to cover the entire area of ​​the right inner side surface of the camera device 3. By providing the metal plate 314, heat dissipation in the camera device 3 can be achieved, and interference of radio waves generated between the first wireless communication module 313 and the second wireless communication module 206 can be further suppressed. In addition, safety can be improved by non-flammable design.

[0087] The metal plate 314 corresponds to the “metal portion” of the present invention.

[0088] In addition, the position of the metal portion 314 opposite to the position where the first wireless communication module 313 is provided is not limited to the right inner side surface 315 of the photographing component 31 or the right inner side surface of the camera device 3. The position opposite to the position where the first wireless communication module 313 is provided can be any position as long as it is based on a predetermined component in the camera device 3. For example, the reference may be the boundary between the first wireless communication module 313 and other components.

[0089] Figure 8 It is a block diagram showing the structure of the imaging device 3.

[0090] like Figure 8 As shown, the first control substrate 311 includes a first processor 320 such as a CPU (Central Processing Unit), a first memory 330, a first communication module 340, and an interface circuit to which other devices and sensors are connected.

[0091] The first memory 330 is a storage device that stores programs and data executed by the first processor 320. The first memory 330 is composed of a non-volatile storage device such as a ROM (Read Only Memory). The first memory 330 may also include a volatile storage device such as a RAM (Random Access Memory) that constitutes a working area of ​​the first processor 320. The first memory 330 stores data processed by the first processor 320 and a control program 331 executed by the first processor 320.

[0092] The first communication module 340 includes hardware such as a communication circuit or a connector in accordance with a predetermined wired communication standard, and communicates with the second control substrate 312 under the control of the first processor 320 .

[0093] The first processor 320 reads and executes the control program 331 , thereby turning the power of the imaging device 3 on and off in accordance with the operation of the power button 32 .

[0094] Furthermore, the first processor 320 reads out and executes the control program 331 to turn on and off the first LED 33 , the second LED 308 , and the third LED 309 .

[0095] Furthermore, the first processor 320 reads out and executes the control program 331 , thereby transmitting the detection values ​​output by each sensor connected to the first control board 311 to the second control board 312 via the first communication module 340 .

[0096] The second control substrate 312 includes a second processor 350 such as a CPU, a second memory 360, a second communication module 370, and an interface circuit for connecting to other devices or sensors.

[0097] The second memory 360 is a storage device that stores programs and data executed by the second processor 350. The second memory 360 is composed of a non-volatile storage device such as a ROM. In addition, the second memory 360 may also include a volatile storage device such as a RAM that constitutes a working area of ​​the second processor 350. The second memory 360 stores data processed by the second processor 350, a control program 361 executed by the second processor 350, and an imaging device ID (Identification) 362.

[0098] The imaging device ID 362 is information for uniquely identifying the imaging device 3 .

[0099] The second communication module 370 includes hardware such as a communication circuit or a connector in accordance with a predetermined wired communication standard, and communicates with the first control substrate 311 under the control of the second processor 350 .

[0100] The second processor 350 functions as a first communication control unit 351 , a second communication control unit 352 , an opening / closing determination unit 353 , a photographing control unit 354 , a recording control unit 355 , and a generating unit 356 by reading and executing a control program 361 stored in the second memory 360 .

[0101] The first communication control unit 351 communicates with the article management server 5 via the first wireless communication module 313 .

[0102] The second communication control unit 352 communicates with the first control board 311 via the second communication module 370. The second communication control unit 352 receives detection values ​​of various sensors connected to the first control board 311 from the first control board 311.

[0103] The opening / closing determination unit 353 determines whether the right door 21B is in the open state or the closed state based on the detection value of the first light sensor 303 received by the second communication control unit 352. When the second communication control unit 352 receives a detection value different from the detection value corresponding to the closed state, the opening / closing determination unit 353 determines that the right door 21B is in the open state. On the other hand, when the second communication control unit 352 receives a detection value corresponding to the closed state, the opening / closing determination unit 353 determines that the right door 21B is in the closed state.

[0104] Similar to the determination regarding the right door 21B, the opening / closing determination unit 353 determines whether the left door 21C is in the open state or the closed state based on the detection value of the second optical sensor 304 received by the second communication control unit 352 .

[0105] The opening and closing judgment unit 353 judges whether the drawer 26A is in an open state or a closed state based on the detection value of the thermopile 305 received by the second communication control unit 352. When the second communication control unit 352 receives the detection value of the thermopile 305 indicating a temperature below the specified temperature, the opening and closing judgment unit 353 judges that the drawer 26A is in an open state. On the other hand, when the second communication control unit 352 receives the detection value of the thermopile 305 indicating a temperature exceeding the specified temperature, the opening and closing judgment unit 353 judges that the drawer 26A is in a closed state.

[0106] When the opening / closing determination unit 353 determines that the door 21A or the drawer 26A is in the open state, the imaging control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to start imaging. In addition, when the imaging control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to start imaging, the second communication control unit 352 sends lighting request information to the first control substrate 311. The lighting request information is information requesting the lighting of the second LED 308 and the third LED 309. When the first processor 320 receives the lighting request information, it lights the second LED 308 and the third LED 309, and notifies the user P that imaging has started.

[0107] When the opening / closing determination unit 353 determines that the door 21A and the drawer 26A are in the closed state, the imaging control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to end imaging. In addition, when the imaging control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to end imaging, the second communication control unit 352 sends an extinguishing request information to the first control substrate 311. The extinguishing request information is information requesting the extinguishing of the second LED 308 and the third LED 309. When the first processor 320 receives the extinguishing request information, it turns off the second LED 308 and the third LED 309, and notifies the user P that imaging is ended.

[0108] When the opening / closing determination unit 353 determines that the door 21A or the drawer 26A is in the open state, the recording control unit 355 starts recording the shooting results of the wide-angle camera 301 and the narrow-angle camera 302. That is, the recording control unit 355 starts recording the recording data 363 in the second memory 360. The recording data 363 includes the first recording data indicating the shooting results of the wide-angle camera 301 and the second recording data indicating the shooting results of the narrow-angle camera 302.

[0109] When the opening / closing determination unit 353 determines that the door 21A and the drawer 26A are in the closed state, the recording control unit 355 ends the recording of the image capturing results of the wide-angle camera 301 and the narrow-angle camera 302 .

[0110] Generator 356 generates management data D1. Management data D1 is data uploaded to article management server 5 and is used to manage articles stored in refrigerator 2. First communication controller 351 transmits management data D1 generated by generator 356 to article management server 5.

[0111] [1-1-4. Structure of the item management server]

[0112] Fig. 9 It is a block diagram showing the configuration of the terminal device 4 and the item management server 5.

[0113] The article management server 5 includes a server processor 50 which is a processor such as a CPU, a server memory 51, and a server communication module 52. The server processor 50 is connected to the server memory 51 and the server communication module 52.

[0114] The server memory 51 is a storage device that stores programs and data executed by the server processor 50. The server memory 51 is composed of a non-volatile storage device. In addition, the server memory 51 may also include a non-volatile storage device that constitutes a work area of ​​the server processor 50. The server memory 51 stores data processed by the server processor 50, a control program 511 executed by the server processor 50, and an item management DB (database) 512.

[0115] The article management DB 512 has one record for each imaging device 3. Each record includes the imaging device ID 362, image data of a first captured image, and image data of a second captured image. The first captured image and the second captured image will be described later.

[0116] Server communication module 52 includes a communication circuit or a connector based on a predetermined communication standard, and communicates with refrigerator 2 , imaging device 3 , and terminal device 4 via network NW.

[0117] The server processor 50 functions as a server communication control unit 501 and a server processing unit 502 by reading and executing a control program 511 stored in the server memory 51 .

[0118] The server communication control unit 501 communicates with the refrigerator 2 , the imaging device 3 , and the terminal device 4 via the server communication module 52 .

[0119] The server processing unit 502 performs various information processing using the camera 3 and the terminal device 4 as clients. The server processing unit 502 may also use the refrigerator 2 as a client.

[0120] [1-1-5. Configuration of terminal device]

[0121] Next, the structure of the terminal device 4 is described.

[0122] The terminal device 4 includes a terminal processor 40 which is a processor such as a CPU, a terminal memory 41 , a terminal communication module 42 , and a touch panel 43 .

[0123] The terminal memory 41 is a storage device that non-volatilely stores programs and data executed by the terminal processor 40. The terminal memory 41 is composed of a non-volatile storage device. In addition, the terminal memory 41 may also include a RAM that constitutes a work area of ​​the terminal processor 40. The terminal memory 41 stores data processed by the terminal processor 40, a control program executed by the terminal processor 40, and an item management application 411.

[0124] The terminal communication module 42 includes a communication circuit or a connector based on a prescribed communication standard, and communicates with the item management server 5 under the control of the terminal processor 40 .

[0125] The touch panel 43 includes a display panel and a touch sensor overlapped with or provided integrally with the display panel.

[0126] The terminal processor 40 functions as an application execution unit 400 .

[0127] The application execution unit 400 communicates with the item management server 5 via the terminal communication module 42 .

[0128] The application execution unit 400 causes the touch panel 43 to display a user interface related to the management of the items stored in the refrigerator 2. In the following description, this user interface is referred to as "application UI." The display control unit 402 of this embodiment displays images of the items stored in the refrigerator 2 and the like by displaying the application UI.

[0129] The application execution unit 400 receives various inputs from the user P via the application UI.

[0130] [1-2. Action]

[0131] Next, the operation of each unit of the article management system 1 will be described.

[0132] [1-2-1. Actions related to video recording]

[0133] First, the operation of the imaging device 3 related to recording will be described.

[0134] Fig.10 FA is a flowchart showing the operation of the imaging device 3 .

[0135] The opening / closing determination unit 353 determines whether the door 21A or the drawer 26A is in the open state (step SA1 ).

[0136] When the opening / closing determination unit 353 determines that the door 21A or the drawer 26A is not in the open state (step SA1 : NO), the second processor 350 returns the process to step SA1 .

[0137] When the opening / closing determination unit 353 determines that the door 21A or the drawer 26A is in the open state (step SA1 : Yes), the imaging control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to start imaging (step SA2 ).

[0138] Next, the recording control unit 355 starts recording the image capturing results of the wide-angle camera 301 and the narrow-angle camera 302 (step SA3 ).

[0139] Next, the opening / closing determination unit 353 determines whether the door 21A and the drawer 26A are closed (step SA4). If the opening / closing determination unit 353 determines that the door 21A and the drawer 26A are not closed (step SA4: No), the determination in step SA4 is performed again.

[0140] On the other hand, when it is determined that the door 21A and the drawer 26A are closed (step SA4 : Yes), the recording control unit 355 ends the recording of the photographing result (step SA5 ). Thus, the recording data 363 is generated in the second memory 360 .

[0141] Next, the imaging control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to end imaging (step SA6 ).

[0142] [1-2-2. Operations related to transmission of management data]

[0143] Next, the operation related to the transmission of the management data D1 will be described.

[0144] Fig.11 This is a flowchart showing the operation of the imaging device 3 and the article management server 5 .

[0145] exist Fig.11 In the flowchart FB, the operation of the imaging device 3 is shown, and the flowchart FC shows the operation of the article management server 5 is shown.

[0146] The generation unit 356 determines whether the recorded data 363 is stored in the second memory 360 (step SB1). When the generation unit 356 determines that the recorded data 363 is not stored (step SB1: No), the determination of step SB1 is performed again.

[0147] On the other hand, when the generating unit 356 determines that the video data 363 is stored (step SB1: Yes), a captured image of a moving image represented by the first video data of the video data 363 stored in the second memory 360 is selected from the first video data stored in the second memory 360 (step SB2).

[0148] Step SB2 will be described in detail.

[0149] The first captured image is a captured image when the right door 21B and the left door 21C are opened at a rotation angle of α°≤θ≤β°, and is a captured image with the least image of the user P. α° is, for example, 60°, and β° is, for example, 100°.

[0150] The generation unit 356 selects a captured image in which a predetermined mark is marked on the door 21A from the dynamic image represented by the first video data. The predetermined mark is marked in advance so as to be captured in the captured image when the right door 21B and the left door 21C meet α°≤θ≤β°. Next, the generation unit 356 selects a captured image in which the user P is least reflected from the selected captured images as the first captured image. The generation unit 356 identifies the user P captured in the captured image by a method such as pattern matching, and sets the captured image in which the image of the identified user P has the smallest area as the captured image in which the user P is least reflected.

[0151] Returning to the description of flowchart FB, the generation unit 356 selects a second captured image from the moving images represented by the second recorded data of the stored recorded data 363 (step SB3 ).

[0152] Step SB3 will be described in detail.

[0153] The second captured image is a captured image of the drawer 26A having a pulled-out degree of γ% or more, when the pulled-out degree of the closed state is set to 0% and the pulled-out degree of the most opened state is set to 100%. The pulled-out degree refers to the degree of being pulled out. In addition, the second captured image is a captured image with the least image of the user P. γ% is, for example, 70%.

[0154] The generator 356 selects a captured image in which a predetermined mark is marked on the inside of the drawer 26A from the dynamic image represented by the second video data. The predetermined mark is marked in advance so as to be captured in the captured image when the drawer 26A is pulled out more than γ%. Next, the generator 356 selects a captured image in which the user P is least reflected from the selected captured images as the second captured image.

[0155] The generation unit 356 determines whether at least one of the first captured image and the second captured image can be selected (step SB4 ).

[0156] When the generation unit 356 determines that the first captured image and the second captured image cannot be selected (step SB4 : No), it performs the process of step SB7 .

[0157] On the other hand, when the generating unit 356 determines that at least one of the first captured image and the second captured image can be selected (step SB4 : Yes), it generates the management data D1 (step SB5 ).

[0158] When the first captured image and the second captured image are selectable, the generating unit 356 generates management data D1 including image data of the first captured image, image data of the second captured image, and the imaging device ID 362 .

[0159] When the first captured image can be selected but the second captured image cannot be selected, the generating unit 356 generates management data D1 including the image data of the first captured image and the imaging device ID 362 .

[0160] When the second captured image can be selected but the first captured image cannot be selected, the generating unit 356 generates management data D1 including the image data of the second captured image and the imaging device ID 362 .

[0161] Next, the first communication control unit 351 transmits the management data D1 generated by the generating unit 356 to the article management server 5 (step SB6).

[0162] Next, the generating unit 356 deletes the recorded data 363 to be processed from the second memory 360 after step SB2 (step SB7 ).

[0163] As shown in flowchart FC, the server communication control unit 501 determines whether the management data D1 is received from the camera device 3 (step SC1). When the server communication control unit 501 determines that the management data D1 is received (step SC1: Yes), the server processing unit 502 updates the item management DB 512 based on the management data D1 received by the server communication control unit 501 (step SC2).

[0164] Step SC2 will be described in detail.

[0165] The server processing unit 502 identifies the record including the camera ID 362 included in the management data D1 from the article management DB 512, and updates the image data of the first captured image of the identified record to the image data of the first captured image included in the management data D1.

[0166] The server processing unit 502 identifies the record including the camera ID 362 included in the management data D1 from the article management DB 512, and updates the image data of the second captured image of the identified record to the image data of the second captured image included in the management data D1.

[0167] [1-2-3. Actions related to application UI]

[0168] Next, the operation of the item management system 1 related to the application UI will be described.

[0169] Fig.124 is a flowchart showing the operation of the terminal device 4 and the article management server 5. Fig.12 Flowchart FD represents the operation of the terminal device 4, and flowchart FE represents the operation of the item management server 5.

[0170] As shown in flowchart FD, the application execution unit 400 determines whether to request image data stored in the article management DB 512 from the article management server 5 (step SD1). For example, when the article management application 411 is activated, the terminal communication control unit 401 makes an affirmative determination in step SD1.

[0171] When the application execution unit 400 determines that the image data stored in the article management DB 512 is requested (step SD1: Yes), it sends request data for requesting the image data to the article management server 5 (step SD2). The request data includes the camera ID 362 stored in the terminal memory 41. In addition, the terminal device 4 obtains the camera ID 362 at a predetermined time.

[0172] As shown in flowchart FE, the server communication control unit 501 receives the request data (step SE1). Next, the server processing unit 502 obtains the image data corresponding to the camera ID 362 included in the request data received by the server communication control unit 501 from the item management DB 512 (step SE2). Next, the server communication control unit 501 sends the image data obtained by the server processing unit 502 to the terminal device 4 as a response to the request data (step SE3).

[0173] Referring to flowchart FD, the application execution unit 400 receives image data from the item management server 5 (step SD3). Next, the application execution unit 400 causes the touch panel 43 to display an application UI including an image indicated by the image data received in step SD3 (step SD4).

[0174] [1-3. Effects, etc.]

[0175] As described above, the article management system 1 includes: a cold storage 2 including a main body 20; and a camera device 3 installed on the top surface 20A of the main body 20 to photograph the cold storage 2. The camera device 3 includes a first wireless communication module 313 capable of transmitting management data D1 for managing articles stored in the cold storage 2. The first wireless communication module 313 is located in front of the opening 201 of the main body 20 when the camera device 3 is installed in the main body 20.

[0176] This can suppress interference caused by the top surface 20A of the main body 20 in radio waves transmitted and received by the first wireless communication module 313. Therefore, the first wireless communication module 313 can stably transmit the management data D1, thereby suppressing a decrease in the management accuracy of the items.

[0177] The cold storage 2 includes a right door 21B and a left door 21C for opening and closing an opening 201, and a second wireless communication module 206 provided on a right door hinge member 204 pivotally supporting the right door 21B. The first wireless communication module 313 is located on the left door hinge member 205 side pivotally supporting the left door 21C than the center ST of the camera device 3 in the left-right direction of the cold storage 2 when the camera device 3 is mounted on the main body 20.

[0178] According to this, since the distance between the first wireless communication module 313 and the second wireless communication module 206 can be ensured, it is possible to suppress the interference of radio waves between the first wireless communication module 313 and the second wireless communication module 206. Therefore, the first wireless communication module 313 can send the management data D1 more stably, so it is possible to further suppress the reduction of the management accuracy of the items.

[0179] The cold storage 2 includes a right door 21B and a left door 21C for opening and closing the opening 201, and a second wireless communication module 206 provided on a right door hinge member 204 that pivotally supports the right door 21B. The camera device 3 includes a metal plate 314. The metal plate 314 is provided between the first wireless communication module 313 and the second wireless communication module 206 in the left-right direction of the cold storage 2 when the camera device 3 is mounted on the main body 20.

[0180] This can further suppress radio interference between the first wireless communication module 313 and the second wireless communication module 206. Therefore, the first wireless communication module 313 can transmit the management data D1 more stably, thereby further suppressing a decrease in the management accuracy of the items.

[0181] Refrigerator 2 includes door 21A that opens and closes opening 201. When imaging device 3 is attached to main body 20, first wireless communication module 313 is located in front of door 21A in a closed state.

[0182] According to this, it is possible to further suppress interference in the radio waves received and sent by the first wireless communication module 313. Therefore, the first wireless communication module 313 can stably send the management data D1, so it is possible to further suppress the reduction in the management accuracy of the items. In addition, assuming that the frame of the door 21A is made of metal, it is also possible to suppress interference in the radio waves received and sent by the first wireless communication module 313, so it is possible to suppress the reduction in the management accuracy of the items.

[0229] According to this, the same effects as those of the article management system 1 in the first embodiment are achieved.

[0230] (Other Embodiments)

[0231] As described above, the above-mentioned embodiments 1 and 2 are described as examples disclosed in this application. However, the technology in the present invention is not limited to this, and can also be applied to embodiments that have been changed, replaced, added, omitted, etc. In addition, the various components described in the above-mentioned embodiments 1 and 2 can also be combined to form a new embodiment. Therefore, other embodiments are exemplified below.

[0232] In the above-mentioned embodiments 1 and 2, the metal plate 314 is shown as an example of the "metal part" of the present invention. However, the "metal part" of the present invention is not limited to the metal plate 314. For example, in the case where the second control substrate 311 is shielded by metal, the "metal part" of the present invention may also be the shield. The second control substrate 311 is arranged between the first wireless communication module 313 and the second wireless communication module 206 in the left-right direction of the cold storage 2. Therefore, the shield has the same effect as the metal plate 314.

[0233] In the above-mentioned embodiments 1 and 2, the third LED 309, the illuminance sensor 307, the human sensor 306, the wide-angle camera 301, the narrow-angle camera 302, the thermopile 305, and the second LED 308 are arranged in sequence at the front end of the imaging unit 31. However, this arrangement order is only an example, and the arrangement order of these components is not limited to the embodiments 1 and 2.

[0234] In the above-mentioned second embodiment, the first optical sensor 303, the second optical sensor 304, the thermopile 305, the human sensor 306, the second LED 308, and the third LED 309 are not included. In other embodiments of the second embodiment, any of these devices may be included.

[0235] In the above-mentioned Embodiments 1 and 2, the right door 21B and the left door 21C have different widths. In other embodiments, the right door 21B and the left door 21C may have the same width, or the left door 21C may have a width greater than the right door 21B.

[0236] In the above-mentioned embodiments 1 and 2, the second wireless communication module 206 is provided on the right door hinge component 204. In other embodiments, the second wireless communication module 206 may be provided on the left door hinge component 205. In this case, the left door 21 is equivalent to the "first door" of the present invention, the right door 21B is equivalent to the "second door" of the present invention, the left door hinge component 205 is equivalent to the "first hinge component" of the present invention, and the right hinge component 204 is equivalent to the "second hinge component" of the present invention.

[0237] In the above-mentioned Embodiments 1 and 2, the imaging device 3 and 3A is configured to include the second LED 308 and the third LED 309. In other embodiments, the second LED 308 and the third LED 309 may be configured by a single LED.

[0238] In the above-mentioned embodiment 1, the case where the sensor for detecting the opening and closing of the drawer 26A is composed of the thermopile 305 is exemplified. However, the sensor for detecting the opening and closing of the drawer 26A may also be a distance sensor. In this case, the opening and closing judgment unit 353 judges whether the drawer 26A is in an open state or a closed state based on the detection value of the distance sensor. When the drawer 26A is pulled out, it is detected as having an action. In addition, the distance sensor may be an infrared method or an ultrasonic method.

[0239] In the above-mentioned second embodiment, the case where the first opening and closing sensor 208 to the sixth opening and closing sensor 213 are composed of Hall ICs is exemplified. However, the first opening and closing sensor 208 and the second opening and closing sensor 209 may also be other sensors such as distance sensors, angle sensors, cameras, and temperature sensors. In addition, the third opening and closing sensor 210 to the sixth opening and closing sensor 213 may also be other sensors such as acceleration sensors, mechanical switches, angle sensors, cameras, and temperature sensors.

[0240] In other embodiments, the following structure may be used: the video recording or shooting of the camera may be terminated after a specified time has passed since the door 21A or the drawer 26A is in the open state. For example, the specified time is 1 minute. In addition, the specified time may be extended when it is detected that the door 21A or the drawer 26A is in the open state, there are people around the cold storage 2, 2A, and the user P is taking out or putting in items. In addition, when it is detected that the door 21A or the drawer 26A is in the open state, there are people around the cold storage 2, 2A, and the user P is taking out or putting in items, the video recording or shooting of the camera may be terminated after a specified time has passed from the moment of detection.

[0241] In other embodiments, when the opening and closing judgment unit 353 judges that the door 21A or the drawer 26A is in the open state, the second LED 308 and the third LED 309 may be turned on. In addition, when the opening and closing judgment unit 353 judges that the door 21A or the drawer 26A is in the closed state, the second LED 308 and the third LED 309 may be turned off. In addition, the lighting or turning off of these LEDs may be controlled according to the shooting status of the camera. For example, in the case of a structure that ends the recording or shooting of the camera after a specified time has passed after the door 21A or the drawer 26A is in the open state, these LEDs are turned off when the recording of the camera is ended. In addition, similarly, these LEDs may be turned off when the shooting of the camera is ended.

[0242] In other embodiments, in addition to the functional units of the second processors 350 and 350A in Embodiments 1 and 2, the second processors 350 and 350A may also function as a detection unit for detecting an object. The detection unit may also cut out images of objects entering and leaving the refrigerating chamber 21 from the dynamic image during the period from the start to the end of the recording of the wide-angle camera 301 and the narrow-angle camera 302 by the recording control unit 355. In addition, when a mark is attached to the object, the detection unit may detect the marked object.

[0243] In other embodiments, in addition to the functional units of the second processor 350 in Embodiment 1, the second processor 350 may also function as a person presence determination unit. The person presence determination unit determines whether there is a person around the cold storage 2 based on the detection value of the human sensing sensor 306. More specifically, the person presence determination unit determines that there is a person around the cold storage 2 when the detection value of the human sensing sensor 306 is a detection value corresponding to the presence of a person, and determines that there is no person around the cold storage 2 when this is not the case. In the case where the second processor 350 functions as the person presence determination unit, when the person presence determination unit determines that there is a person, the shooting control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to start shooting, and when the person presence determination unit determines that there is no person, the shooting control unit 354 causes the wide-angle camera 301 and the narrow-angle camera 302 to end shooting. In addition, when the second processor 350 functions as a person presence determination unit, when the person presence determination unit determines that a person is present, the recording control unit 354 starts recording, and when the person presence determination unit determines that a person is not present, the recording control unit 355 ends recording. Thus, even when the opening and closing determination unit 353 makes an erroneous determination, the shooting results of the wide-angle camera 301 and the narrow-angle camera 302 can be properly recorded.

[0244] In other embodiments, in addition to the functional units of the second processors 350 and 350A in embodiments 1 and 2, the second processors 350 and 350A may also function as an entry and exit judgment unit. In this case, the entry and exit judgment unit changes the boundary line used for the entry and exit judgment according to the opening and closing angles of the left door 21C and the right door 21B, and judges the entry and exit of the article. In addition, the entry and exit judgment unit changes the boundary line used for the entry and exit judgment according to the pulling degree of the drawer 26A, and judges the entry and exit of the article.

[0245] In other embodiments, the first captured image may be subjected to image correction and uploaded to the article management server 5. As an example of image correction, correction of viewpoint conversion is exemplified.

[0246] In the above-described embodiment, the first captured image and the second captured image are used for display purposes of the terminal device 4. However, the first captured image and the second captured image may be used for other purposes such as detecting articles stored in the cold storage 2 or 2A.

[0247] In other embodiments, the compartments formed in the main body 20 of the refrigerator 2, 2A may have storage rooms other than the above five types, or may be fewer. In other embodiments, the number of doors provided in the opening 201 of the refrigerating chamber 21 may be one.

[0248] The first processor 320, 320A, the second processor 350, 350A, the server processor 50, and the terminal processor 40 may be composed of a single processor or a plurality of processors. These processors may also be hardware programmed in a manner to implement corresponding functional units. That is, these processors may also be composed of, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).
