Description

  The present invention relates to a terminal device.

  The economic value of a harvested object of a plant such as a fruit greatly depends on the content (for example, sugar content) of a specific component contained in the harvested object. In general, a harvested object in which sugar content is regarded as important is measured for sugar content by near infrared light irradiation and an optical sensor after being harvested.

  For example, Patent Document 1 discloses that a light source is rotated relative to a harvesting target while irradiating the harvesting target with light and spectrally analyzing light transmitted through the harvesting target. It is described that the distribution of sugar content in an object is measured.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

  In the following description, the harvest determination device 100 indicates a functional unit block, not a hardware unit configuration. For example, the prediction unit 120 is realized by an arbitrary combination of hardware and software centering on an arbitrary computer CPU, memory, a program loaded into the memory, a storage medium such as a hard disk for storing the program, and a network connection interface. Is done. There are various modifications of the implementation method and apparatus.

  FIG. 1 is a diagram illustrating a configuration of a harvest determination device 100 according to the embodiment. The harvest determination device 100 according to the embodiment includes a concentration measurement unit 110 and an estimation unit 120. The concentration measuring unit 110 measures the concentration (an example of growth information) of a specific component contained in the harvest object F. The prediction unit 120 predicts the harvesting timing of the harvested object F based on the history of measurement results obtained by the concentration measurement unit 110. The harvest object F is, for example, a fruit of a plant P, for example, a fruit such as a melon, a watermelon, a peach, an apple, or a mango, but is not limited thereto. The harvest determination device 100 is used in, for example, a plant factory, but is not limited thereto. Details will be described below.

  The concentration measurement unit 110 measures the concentration of a specific component (hereinafter referred to as a specific component) included in the harvest target F multiple times (for example, periodically). The concentration measuring unit 110 determines the concentration of the specific component contained in the harvested object F based on, for example, the intensity of light or reflected waves that have passed through the harvested object F. For example, when the specific component is sugar, the light detected by the concentration measuring unit 110 is near infrared light. The light source detected by the concentration measurement unit 110 includes a light emitting element such as an LED or an organic EL element, and is disposed near the harvest target F.

  The prediction unit 120 predicts the harvest timing of the harvest target F based on the measurement result history of the concentration measurement unit 110. An example of details of processing performed by the prediction unit 120 will be described later with reference to FIGS. Then, the prediction unit 120 outputs a prediction result. This prediction result is output to the outside as, for example, character data indicating the harvest timing, or image data indicating the history of the measurement result and the expected transition.

  In addition, the harvest determination device 100 further includes a measurement result storage unit 122. The measurement result storage unit 122 stores the measurement result by the concentration measurement unit 110 in association with the measurement date and time. When there are a plurality of harvest objects F (or plants P), the measurement result storage unit 122 identifies the measurement results and measurement date and time by the concentration measurement unit 110 as information for identifying the harvest objects F (or plants P) from each other (hereinafter identified). Information and description). This identification information is input to the concentration measuring unit 110 when measuring the harvest object F, for example. Then, the prediction unit 120 predicts the harvest timing of the harvest object F using the information stored in the measurement result storage unit 122.

  The measurement result storage unit 122 may be provided at a location different from the harvest determination device 100. In this case, the measurement result storage unit 122 communicates with the prediction unit 120 via a communication line.

  FIG. 2 is a diagram for explaining a first example of processing performed by the prediction unit 120. In the example shown in this figure, the prediction unit 120 predicts the harvest timing of the harvest object F using an approximate expression. For example, it is determined that the harvest object F has reached the harvest timing when the concentration of the specific component is equal to or higher than the reference value. Here, the prediction unit 120 predicts the timing at which the concentration of the specific component becomes equal to or higher than the reference value (that is, the harvesting timing) by applying the transition of the concentration of the specific component to a predetermined approximate expression.

  FIG. 3 is a diagram for explaining a second example of processing performed by the prediction unit 120. In the example shown in this figure, the prediction unit 120 predicts the harvest timing based on the difference in the concentration of the specific component between the different measurement timings. Specifically, the prediction unit 120 calculates the difference (ΔC) between the concentration of the specific component in the latest measurement result and the concentration of the specific component in the previous measurement result. Then, the prediction unit 120 determines the history of ΔC and predicts the timing when ΔC becomes equal to or less than the reference value. And this prediction timing is judged as a harvest timing. In this case, even when the concentration of the specific component does not increase in the specific harvest target F due to the solid difference of the harvest target F, the harvest timing of the harvest target F can be predicted.

  As described above, according to the present embodiment, the prediction unit 120 predicts the harvest timing of the harvest target F based on the measurement result history of the concentration measurement unit 110. Therefore, it becomes easy to make a shipping plan for the harvested object F.

  Note that the prediction unit 120 may correct the harvesting timing by subtracting the expiration date or the time required for distribution from the harvesting timing obtained in the examples shown in FIGS. Specifically, when the time required for distribution is about 5 days, the prediction unit 120 sets an expected date of harvest timing so that the concentration of the specific component becomes the highest after one week. If it does in this way, the density | concentration of the specific component in the harvest target F will become the highest at the timing which reaches a consumer.

Example 1
FIG. 4 is a diagram illustrating the configuration of the harvest determination device 100 according to the first embodiment. The harvest judgment device 100 shown in the figure has the same configuration as the harvest judgment device 100 according to the embodiment except that a measurement result storage unit 122, a reference storage unit 124, and an input unit 130 are provided.

  The measurement result storage unit 122 stores a history of measurement results of the concentration measurement unit 110. For example, the measurement result storage unit 122 stores the measurement result of the concentration measurement unit 110 in association with information indicating the measurement date and time. When the identification information is given to the harvest object F, the measurement result storage unit 122 stores the measurement result of the concentration measurement unit 110 in association with the identification information of the harvest object F. Then, the prediction unit 120 predicts the harvest timing of the harvest object F using the information stored in the measurement result storage unit 122.

  The reference storage unit 124 stores information used when the prediction unit 120 predicts the harvest timing of the harvested object F. For example, when the prediction unit 120 predicts the harvest timing using an approximate expression, the reference storage unit 124 stores information for generating this approximate expression. Further, when the prediction unit 120 predicts the harvest timing based on the difference in the concentration of the specific component between the different measurement timings, the reference storage unit 124 corresponds, for example, to the time necessary to reach the harvest timing. I remember it.

  Moreover, the reference | standard memory | storage part 124 has memorize | stored the information used when estimating the harvest timing of the harvest target F for every kind of the harvest target F. For this reason, the prediction unit 120 can vary the prediction criterion of the harvest timing for each type of the harvest object F. If it does in this way, the precision of the prediction of the harvest timing of the harvest target F will become high.

  The input unit 130 includes an input device such as a touch panel or a keyboard, for example, and the type of the harvest object F is input. The prediction unit 120 reads out information corresponding to the type of the harvest object F input to the input unit 130 from the reference storage unit 124 and uses it. Note that the information indicating the type of the harvest target F input to the input unit 130 is stored in the measurement result storage unit 122 in association with the identification information of the harvest target F. When predicting the harvest timing of the harvest object F again, the prediction unit 120 determines the type of the harvest object F using the information stored in the measurement result storage unit 122.

  Also according to this example, the same effect as the embodiment can be obtained. Moreover, since the prediction standard of the harvest timing can be varied for each type of the harvest object F, the accuracy of the prediction of the harvest timing of the harvest object F is increased.

(Example 2)
FIG. 5 is a diagram illustrating a configuration of the plant growth system 10 according to the second embodiment. The plant growth system 10 according to the present embodiment is used in, for example, a plant factory, and includes a harvest determination device 100, an irradiation unit 200, a classification device 300, a harvesting device 310, a refrigeration device 320, and a cooling unit 330. The harvest determination device 100 has the same configuration as that of the first embodiment.

  In the plant growth system 10, a plurality of plants P are circulated by an annular circulation moving unit 210, for example, a belt conveyor. An irradiation unit 200 is provided above the plurality of plants P. The irradiation unit 200 irradiates the plant P with light having a wavelength suitable for the growth of the plant P. Here, the irradiation unit 200 may change the wavelength of light according to the growth stage of the plant P.

  The plurality of plants P is given identification information for identifying each other. This identification information is memorize | stored in the IC chip attached to the growth container of the plant P, for example. The harvest determination device 100 uses the identification information of the plant P as the identification information of the harvest object F. Then, the harvest determination device 100 predicts the harvest timing of the harvest target F that the plant P has, as in the first embodiment. At this time, the harvest determination device 100 reads the identification information of the plant P having the harvest target F to be inspected from the above-described IC chip. Further, the prediction unit 120 of the harvest determination device 100 determines that the harvest target F should be harvested when the concentration of the specific component in the harvest target F satisfies the standard. Then, the harvest determination device 100 outputs identification information corresponding to the harvest object F determined to be harvested to the classification device 300.

  A cooling unit 330 is provided on a part of the circulation moving unit 210. The cooling unit 330 cools the plant P to such an extent that it does not freeze. Preferably, the humidity is also kept above a certain value. Thereby, depending on the type of plant P (for example, leafy vegetables such as cabbage and Chinese cabbage, asparagus, etc.), the concentration of specific components (for example, sugar content and free amino acids) of the harvested object F increases. This is considered to prevent the plant P itself from freezing.

  In the present embodiment, the measurement result storage unit 122 of the harvest determination device 100 stores the operation history of the irradiation unit 200 and the cooling unit 330 in addition to the measurement result history of the concentration measurement unit 110.

  The classification device 300 is provided in a part of the circulation moving unit 210, and reads the identification information of the plant P passing through the classification device 300 from the above-described IC chip. Then, when the read identification information coincides with the identification information received from the harvest determination device 100, the classification device 300 separates the plant P from the circulation moving unit 210 in order to harvest the harvest object F. Move to root.

  Then, the harvest object F of the plant P that has moved to a route different from the circulation moving unit 210 is harvested and boxed by the harvesting device 310 and stored in the refrigerated state (preferably further in a high humidity state) by the refrigeration device 320. The refrigeration apparatus 320 may store the harvest object F in a state where the humidity is further increased.

  Also according to the present embodiment, the harvest timing of the harvest target F can be predicted with high accuracy, so that it becomes easy to make a shipping plan for the harvest target F. Moreover, since the cooling unit 330 is provided on a part of the circulation moving unit 210, the sugar content of the harvested object F is likely to increase.

  In the example shown in FIG. 5, the plants P (and the harvesting object F) are arranged in a line, but the arrangement order of the plants P may vary depending on the growth state and sugar content of each plant P and the harvesting object F. It may be replaced. For example, the plants P in which the growth state and the sugar content of the harvested object F are in the same range may be rearranged and grouped so that the operations of the irradiation unit 200 and the cooling unit 330 are optimized for each group.

(Example 3)
FIG. 6 is a diagram illustrating a configuration of the plant growth system 10 according to the third embodiment. The plant growth system 10 according to the present embodiment has the same configuration as the plant growth system 10 according to the second embodiment except for the following points.

  First, the harvest determination device 100 outputs, to the classification device 300, the identification information of the plants P whose period until the expected timing of the harvest timing of the harvest target F is equal to or less than the reference. The classification device 300 removes the plant P that has received the identification information from the circulation moving unit 210 and ships it. The plant P is delivered to the customer with the unharvested harvesting object F attached.

  FIG. 7 is a diagram for explaining the handling of the plant P after shipment. A customer who has received the plant P has a user terminal 400. The user terminal 400 can communicate with the harvest determination device 100 via the public communication line 20. The user terminal 400 transmits the measurement information of the harvest object F to the harvest determination device 100 via the public communication line 20. The harvest judgment device 100 uses the new measurement information received from the user terminal 400 and the measurement information (including the measurement information in the plant growth system 10) stored in advance in the measurement result storage unit 122, to be harvested. Predict the harvest timing of F. Then, the harvest determination device 100 transmits the prediction result to the user terminal 400 via the public communication line 20.

  FIG. 8 is a diagram illustrating a configuration of the user terminal 400. The user terminal 400 is a portable terminal and includes a measurement unit 410 and a communication unit 420. The measurement unit 410 acquires measurement information of the harvest object F. Here, the measurement unit 410 has the same function as the concentration measurement unit 110 of the harvest determination device 100. The user terminal 400 can use a general-purpose mobile communication terminal such as a smartphone. In the latter case, the measurement unit 410 acquires the concentration of the specific component contained in the harvest target F as measurement information.

  The communication unit 420 communicates with the harvest determination device 100 via the public communication line 20. The communication unit 420 has a wireless communication function, for example. The communication unit 420 transmits the measurement information measured by the measurement unit 410 to the harvest determination device 100 in association with the identification information of the plant P. The identification information of the plant P is read by the measurement unit 410, for example.

  FIG. 9 is a diagram illustrating a configuration of the harvest determination device 100 according to the present embodiment. The harvest determination device 100 shown in the figure has the same configuration as the harvest determination device 100 according to the first embodiment except that the communication unit 140 (reception unit and transmission unit) is provided. The communication unit 140 receives measurement information and plant P identification information transmitted from the user terminal 400 (an example of an external device). The prediction unit 120 reads the measurement information history corresponding to the identification information of the plant P received by the communication unit 140 from the measurement result storage unit 122, and uses the read history and the measurement information received by the communication unit 140 to harvest. Predict the harvest timing of the object F. Further, the prediction unit 120 causes the measurement result storage unit 122 to store the newly received measurement information in association with the identification information of the plant P. Then, the communication unit 140 transmits the prediction result of the prediction unit 120 to the user terminal 400.

  Further, when the harvesting timing of the harvested object F approaches, the prediction unit 120 transmits harvest promotion information indicating that the harvesting timing is approaching to the user terminal 400 via the communication unit 140. Thereby, the user of the user terminal 400 can recognize that the harvest timing of the harvest object F is approaching.

  Each diagram in FIG. 10 is a diagram illustrating a display example of harvest promotion information on the user terminal 400. In the examples shown in these figures, the harvest promotion information indicates the time until the scheduled harvest date (the number of days in the example shown in this figure). The display changes depending on the time based on the scheduled harvest date. Further, the harvest promotion information includes the history of the plant S, the recommended storage environment after harvesting, and the nutrition amount. Although not shown in the figure, the harvest promotion information may be accompanied by a standard image of the harvest object F at that timing.

  Note that since the type of the harvest target F is already stored in the measurement result storage unit 122, the user of the user terminal 400 does not need to input the type of the harvest target F to the user terminal 400.

  Further, the measurement unit 410 of the user terminal 400 may acquire a color image of the harvest target F as measurement information. In this case, the growth information includes information indicating the color of the harvest object F. Then, the prediction unit 120 of the harvest determination device 100 predicts the harvest timing of the harvest target F based on the color of the harvest target F, for example, the area ratio of the specific color in the harvest target F.

  According to the present embodiment, since the user of the user terminal 400 obtains the plant P after the harvest target F has been grown to some extent, the harvest target is compared with the case where the user grows the plant P from the beginning. The possibility of harvesting F increases. And it can enjoy the process until the harvest object F grows up and can be harvested. At this time, since the harvest timing of the harvested object F can be predicted, the pleasure is further increased.

  As mentioned above, although embodiment and the Example were described with reference to drawings, these are illustrations of this invention and can also employ | adopt various structures other than the above.
