For example, the sensing information processing device 100 may further include a memory (not shown) for storing sensing information. Alternatively, in the case of other embodiments, those skilled in the art may understand that some of the components shown in FIG. 1 may be omitted.

The sensing information processing device 100 according to an embodiment may be used by a user or a worker, and may include a touch screen panel such as a mobile phone, a smart phone, a personal digital assistant (PDA), a portable multimedia player (PMP), a tablet PC, and the like.

It may be included in or interlocked with the prepared device.

The sensing information processing device 100 may be implemented as a terminal such as a computer that operates through a computer program for realizing the functions described in this specification.

The sensing information processing device 100 according to an embodiment may provide a server outputting a notification signal and an application supporting the same. The sensing information processing device 100 may operate independently to output a notification signal, and may perform an operation of outputting a notification signal through interworking with a server and an application.

Hereinafter, the description will focus on an embodiment in which the sensing information processing device 100 according to an embodiment independently outputs a notification signal, but as described above, the notification signal may be output through interworking with a server and an application. . That is, it can be seen that the sensing information processing device 100 and the server according to an embodiment may be integrated and implemented in terms of their functions, and the server may be omitted, and is not limited to any one embodiment.

2 is a flowchart illustrating each step in which the sensing information processing device 100 operates according to an exemplary embodiment.

In step S210, the sensing information processing device 100 may acquire sensing information by sensing vibration or sound generated as coffee beans are roasted.

This sensing information is obtained by the sensor 110 including the vibration sensor 110 and the sound sensor 110, and may include vibration sensing information about vibration and sound sensing information about sound.

The sensing information processing device 100 is configured to be integrated with the sensor 110 and is located in an area adjacent to the roasting device, or the sensor 110 is separately located in an area adjacent to the roasting device and the sensing information processing device 100 is located in the area adjacent to the roasting device. ) location and may be provided in a separate location. As such, the sensing information processing device 100 and the sensor 110 may be implemented in an independent or integrated form, and may be implemented in a form that operates in different locations.

In step S220, the sensing information processing device 100 may determine the occurrence time of the first crack based on the sensing information obtained in step S210.

For example, coffee beans are broken at a specific point in the roasting process. This phenomenon is generally referred to as a crack phenomenon. frequency can be generated.

When it is indicated that a frequency of about 250 Hz is detected from the sound sensing information according to the sensing information, the sensing information processing device 100 determines the time of occurrence of the first crack based on the time when the sound sensing information at which the corresponding frequency is detected is obtained. can

In step S230, the sensing information processing device 100 may determine the time of discharging the coffee beans based on the generation time of the first crack determined in step S220 and the preset DTR.

The coffee bean discharge time may be determined based on vibration sensing information.

For example, if the vibration according to the vibration sensing information is irregular and relatively large, it can be regarded that the quality of roasting coffee beans is not uniform. Coffee beans of such uneven quality may require more time for roasting.

Specifically, the sensing information processing device 100 may determine an expected coffee bean discharge time based on the occurrence time of the first crack and the preset DTR.

For example, DTR may indicate a time ratio for performing additional roasting to a time from a roasting start point to a first crack occurrence point. The preset DTR may be determined, for example, at a rate of about 13% of the time from the start of roasting to the time the first crack occurs, but is not limited thereto, and the roasting time may cause a difference in the quality and taste of the roasting result. Therefore, the preset DTR may be determined at an arbitrary ratio designated for each user.

Then, the sensing information processing device 100 may determine the homogeneity of coffee beans based on the vibration sensing information.

For example, the homogeneity of coffee beans may represent the degree of uniformity of the quality of coffee beans. If it can be determined that the degree is low and the vibration is regular and small, the device processing the sensing information can determine that the homogeneity of the coffee bean is high.

In one example, if the homogeneity of coffee beans is low, since the quality of coffee beans can be considered to be non-uniform, in this case, roasting for a relatively long time can obtain a higher homogeneity result, When is high, the quality of the coffee beans is relatively uniform and additional roasting may not be required.

Based on this point, the sensing information processing device 100 may determine a delay time for the coffee bean discharge time based on the homogeneity of the coffee beans.

For example, when the homogeneity of coffee beans is low, the sensing information processing device 100 may determine the delay time as a value increased by a preset time (or ratio), and conversely, when the homogeneity of coffee beans is high, delay The time may be determined as a value reduced by a predetermined time (or ratio) or the value may be determined as zero.

Thereafter, the sensing information processing device 100 may update the expected coffee bean discharge time according to the determined delay time to determine the coffee bean discharge time.

In one embodiment, the delay time may be inversely proportional to the degree of homogeneity. For example, if the homogeneity is low, the quality of the coffee beans can be considered to be uneven, so in this case, it may be desirable to proceed with the roasting for a relatively long time, so the delay time can be determined to be large, and on the contrary, the homogeneity of the coffee beans If the degree is high, additional time may not be required for roasting, so the delay time may be determined to be small. As such, the delay time and the degree of homogeneity may be in inverse proportion to each other.

In one embodiment, the sensing information processing device 100 may determine the homogeneity of coffee beans based on the number of frequencies corresponding to vibrations of a predetermined size or more and the time for which vibrations of a predetermined size or more are maintained.

For example, when the quality of coffee beans being roasted is uniform, vibrations of a certain magnitude, which are neither large nor small, occur for a certain period of time and then decrease. If the quality of roasting coffee beans is not uniform, large vibrations may appear for a relatively long time.

Accordingly, the sensing information processing device 100 may determine the homogeneity of coffee beans low when the number of frequencies corresponding to vibrations of a predetermined magnitude or more is large, and the homogeneity of coffee beans high when the number of frequencies is small, The homogeneity of the coffee beans may be determined to be low when the time for which the vibration of the predetermined size or more is maintained is long, and the homogeneity of the coffee beans may be determined to be low when the time for which the vibration is maintained is short.

The sensing information processing device 100 updates the expected coffee bean discharge time according to the delay time determined in this way, determines the coffee bean discharge time, and obtains a higher quality roasting result using sound and vibration. You can decide when you can.

In step S240, the sensing information processing device 100 may output a notification signal indicating the coffee bean discharge time.

In one embodiment, the notification signal may include a discharge request signal requesting the roasting device to discharge coffee beans. The discharge request signal may include a signal requesting the user to end roasting of coffee beans and to discharge the result of roasting.

In the case of providing such a notification signal, the sensing information processing device 100 may be included in one side of the roasting device, for example, to effectively provide the notification signal, but is not limited thereto.

In one embodiment, the notification signal may include at least one of a sound signal, a vibration signal, and a visual signal notifying the time of dispensing coffee beans.

In the case of providing such a notification signal, in order to effectively provide the notification signal, the sensing information processing device 100 may be implemented as a device separate from the roasting device, and may be attached to the roasting device or an area adjacent to the roasting device. can be implemented as

In addition, the notification signal may include the remaining time until the coffee bean is discharged. For example, referring to FIG. 4 , the sensing information processing device 100 may provide the remaining time until coffee bean discharge time in a countdown format based on the coffee bean discharge time point. In the case of outputting notification signals of this type, the sensing information processing device 100 outputs notification signals according to countdown start, progress, and end together so that the user can effectively recognize that the discharge time is approaching. .

In an embodiment, the sensing information processing device 100 may obtain a first crack occurrence time according to a user input and update a frequency value, which is a criterion for determining a first crack occurrence time, based on this.

For example, when the frequency value at the time of occurrence of the first crack determined according to the user input is 260 Hz and the preset reference frequency value for determining the time of occurrence of the first crack is 250 Hz, the sensing information processing device 100 The reference frequency value may be updated to reflect the user's judgment. The ratio at which the user's judgment is reflected in updating the reference frequency value is a predetermined ratio (e.g., 50 %) can be.

Additionally, when the number of times the first crack occurrence time is obtained according to the user input is equal to or greater than the preset number of times, the sensing information processing device 100 determines the number of times the first crack occurrence time according to the user input is obtained. The ratio can be updated. By doing so, the user's judgment is reflected more and the convenience of the user's operation can be improved.

In another embodiment, the user may determine the discharge time while recognizing the occurrence time of the first crack according to his or her own judgment, tendency, and the like. In this case, since the decision may be made according to the time of occurrence of the first crack or the user's judgment or propensity for the DTR, the sensing information processing device 100 may output a notification signal informing of the time of occurrence of the first crack, and If the discharge time according to the user input is obtained after outputting the notification signal for the occurrence time of the crack, the coffee bean value determined based on the occurrence time of the first crack and the preset DTR based on the discharge time according to the user input The release time can be updated.

The rate at which the discharge time according to the user input used to update the coffee bean discharge time determined based on the first crack generation time and the preset DTR may be a preset rate (eg, 50%).

Also, the preset DTR may be updated based on user input. For example, when the discharge time is updated according to a user input, the preset DTR may be updated based on the updated discharge time.

In another embodiment, when the roasting result is discharged as the dispensing time is updated according to the user input, the sensing information processing device 100 may obtain a quality score for the roasting result from the user.

For example, when the discharge time is updated by reflecting the user input, the quality of the roasting result may differ from the user's expectation.

Accordingly, when the quality score of the roasting result acquired from the user is equal to or greater than the preset score, since the reliability of the user input can be regarded as high, the sensing information processing device 100 determines the occurrence time of the first crack and the preset DTR. In order to update the determined discharge time based on the user input, a ratio reflecting the discharge time may be updated.

Conversely, when the quality score of the roasting result obtained from the user is less than the predetermined score, since the reliability of the user input can be regarded as low, the sensing information processing device 100 determines the occurrence time of the first crack and the preset DTR. In order to update the discharge time determined based on the user input, the discharge time according to the user input may not be reflected or the reflected rate may be updated at a low rate (eg, 20%).

By doing this, a roasting result in which the user input and sensing information are appropriately reflected may be obtained.

Figure 3 is a flow chart showing each step of determining the discharge time according to an embodiment.

In step S310, the sensing information processing device 100 may determine an expected coffee bean discharge time based on the occurrence time of the first crack and the preset DTR.

For example, DTR may indicate a time ratio for performing additional roasting to a time from a roasting start point to a first crack occurrence point. The preset DTR may be determined, for example, at a rate of about 13% of the time from the start of roasting to the time the first crack occurs, but is not limited thereto, and the roasting time may cause a difference in the quality and taste of the roasting result. Therefore, the preset DTR may be determined at an arbitrary ratio designated for each user.

In step S320, the sensing information processing device 100 may determine the homogeneity of coffee beans based on the vibration sensing information.

For example, the homogeneity of coffee beans may represent the degree of uniformity of the quality of coffee beans. If it can be determined that the degree is low and the vibration is regular and small, the device processing the sensing information can determine that the homogeneity of the coffee bean is high.

In step S330, the sensing information processing device 100 may determine a delay time for the coffee bean discharge time based on the homogeneity of the coffee beans.

For example, when the homogeneity of coffee beans is low, the sensing information processing device 100 may determine the delay time as a value increased by a preset time (or ratio), and conversely, when the homogeneity of coffee beans is high, delay The time may be determined as a value reduced by a predetermined time (or ratio) or the value may be determined as zero.

In step S340, the sensing information processing device 100 may update the expected coffee bean discharge time according to the delay time to determine the coffee bean discharge time.

In this way, the final discharge time of coffee beans is determined by updating the expected discharge time of coffee beans based on the first crack generation time determined according to the sound sensing information and the vibration sensing information and the preset DTR, thereby discharging according to manual operation. It is possible to reduce the error of viewpoint and to obtain a relatively high quality roasting result.

4 is a diagram schematically illustrating an example in which a notification signal is provided according to an embodiment.

Referring to the drawing, the sensing information processing device 100 may output a notification signal indicating the determined coffee bean discharge time as shown in the drawing.

Referring to the drawing, the notification signal may include the remaining time until coffee beans are discharged. For example, the sensing information processing device 100 may provide the remaining time until coffee bean discharge time in a countdown format based on the coffee bean discharge time point. When outputting notification signals of this type, the sensing information processing device 100 outputs notification signals corresponding to countdown start, progress, and end together so that the user can effectively recognize the situation up to discharge.
