FIG. 3 is a perspective view schematically showing the appearance of the vinyl house 300 in which the dimming system 100 is installed. The vinyl house 300 (corresponding to a facility that is a greenhouse) is a front-view kamaboko-shaped structure in which a plurality of pipe-shaped bone members are connected at appropriate positions with a fastener to form a sheet material made of a synthetic resin film. The sheet material is provided so as to give tension. In the vinyl house 300, the gable-shaped roof portion 301 is supported by the side surface portions 302 from both sides in the inclined direction, and the end face portion 303 closes the end faces facing each other in the longitudinal direction.

The dimming members 3, 3, ... 3 are arranged and installed in the area where the height on the roof portion 301 is relatively high, but they do not necessarily have to be aligned. The dimming members 3, 3, ... 3 may be installed on the side surface portion 302. The dimming members 3, 3, ... 3 are installed on either the upper surface side or the lower surface side of the roof portion 301, or on the outer side or the inner side of the side surface portion 302. The dimming members 3, 3, ... 3 themselves may form a part of the roof portion 301 or the side surface portion 302.

In the first embodiment, the arrangement in the longitudinal direction of a series of regions in the vinyl house 300 is referred to as a "row", and the arrangement in the direction orthogonal to the longitudinal direction is referred to as a "column". In FIG. 3, the dimming members 3, 3, ... 3 are installed in the installation area of 2 rows and 4 columns, but are not limited to this, and are installed in the installation area of 1 row or 3 rows or more. It may be installed in the installation area of 1 to 3 rows or 5 rows or more.

Solar panels 4, 4, 4 are installed side by side in the area where the height on the roof 301 is relatively low. The solar panels 4, 4, ... 4 do not necessarily have to be installed on the vinyl house 300, but it is preferable that the solar panels 4, 4, ... 4 are installed in a sunny position outside the vinyl house 300. The solar radiation sensor 15 is installed at an appropriate position on the roof portion 301, for example.

FIG. 4 is a schematic perspective view of the inside of the vinyl house 300 as viewed from the end face portion 303. The installation area in the mth row and nth column (m and n are natural numbers) is represented by Ra [m, n]. It is assumed that the side surface portion 302 located on the right side of the paper surface faces south. The installation areas on the sloped portion on the south side of the roof portion 301 are Ra [1,1] to Ra [1,4] in order from the west side. Further, the installation area on the inclined portion on the north side of the roof portion 301 is Ra [2,1] to Ra [2,4] in order from the west side. The imaging unit 17 is installed downward in the central portion of the lower surface of the roof portion 301.

Of the imaging areas included in the bird's-eye view image captured by the imaging unit 17, the exposure area of the open ground corresponding to each of the installation areas Ra [1,1] to Ra [2,4] of the dimming members 3, 3, ... Let be Rb [1,1] to Rb [2,4]. Each of the imaging areas Rb [1,1] to Rb [2,4] is, for example, an area in which the installation areas Ra [1,1] to Ra [2,4] are projected onto the open ground from one point outside the greenhouse 300. is there. This one point may be a fixed point, or may be, for example, a point that changes with the movement of the sun on the celestial sphere. In this case, a table for converting the position of the sun on the celestial sphere with respect to the date and time is stored, and the imaging regions Rb [1,1] to Rb [2] are stored according to the position of the sun converted using the table. 4] may be determined.

FIG. 5 is a cross-sectional view schematically showing the configuration of the dimming member 3. The dimming member 3 includes two EC (Electrochromic) layers 32a and 32b with an electrolyte layer 31 interposed therebetween, and is transparent on the surface of each of the EC layers 32a and 32b opposite to the electrolyte layer 31 side. Electrodes 33a and 33b are formed. Each of the transparent electrodes 33a and 33b is a conductive layer formed on one surface of a transparent base material 34a and 34b such as glass. That is, the transparent electrode 33a, the EC layer 32a, the electrolyte layer 31, the EC layer 32b, and the transparent electrode 33b are laminated in this order between the two transparent base materials 34a and 34b. A sealing material 30 for sealing the electrolyte is provided at the end of the electrolyte layer 31.

The electrolyte layer 31 is a carrier supply layer that supplies electrons or ions to the EC layers 32a and 32b. As the electrolyte, various forms such as solid, liquid, and gel can be used. As the ion source, lithium salt, sodium salt, potassium salt and the like are mainly used.

The EC layers 32a and 32b contain compounds that develop color by a redox reaction. For example, when an oxidation-type coloring compound that develops color by an oxidation reaction is used for the EC layer 32a and a reduction-type coloring compound that develops color by a reduction reaction is used for the EC layer 32b, the EC layers 32a and 32b develop color when energized. It becomes a light-shielded state, and when the energization is stopped, the color fades and becomes transparent. As a combination of color-developing compounds that bring about such changes, for example, polyethylene dioxythiophene (PEDOT) and polyaniline (polyaniline) are used.

The transparent electrodes 33a and 33b are transparent conductive layers containing, for example, indium tin oxide (ITO = Indium Tin Oxide). A take-out electrode (not shown) for connecting to the drive unit 18 is provided at one end of each of the transparent electrodes 33a and 33b.

The transparent substrates 34a and 34b are not limited to glass, and an insulating film that is colorless and transparent and has flexibility in the visible light region may be used. For example, polyester resins such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN) are preferable.

The dimming member 3 supplies an electric current between the transparent electrodes 33a and 33b from the drive unit 18 to transfer ions between the EC layers 32a and 32b via the electrolyte layer 31. As a result, the EC layers 32a and 32b are redox-reduced to develop a color (transparent → colored), and the color of the transmitted light changes. The structure of the dimming member 3 is such that the transparent electrodes 33a and 33b and the EC layers 32a and 32b face each other via the electrolyte layer 31, but the structure is not necessarily limited to this structure. The design may be flexibly changed according to the request, such as those having the EC layer 32a or 32b on only one side or those having no sealing material 30.

FIG. 6 is a graph illustrating the wavelength characteristics of the light transmittance of the dimming member 3. The horizontal axis of the figure represents the wavelength of light (nm), and the vertical axis represents the transmittance of light (%). In the example shown in FIG. 6, when the dimming member 3 develops color by the current from the drive unit 18 (indicated by the broken line), the light transmittance is 3% in the wavelength region including the visible light region where the wavelength is 380 nm to 780 nm. It drops below. On the other hand, when the dimming member 3 fades and becomes transparent (indicated by a solid line), the light transmittance increases to 60 to 70% in a wavelength region including a visible light region excluding a part on the short wavelength side.

The color of the dimming member 3 at the time of color development changes due to the difference in the color-developing compound contained in the EC layers 32a and 32b. That is, the wavelength range when the light transmittance changes can be arbitrarily changed. Further, by controlling the magnitude of the current supplied from the drive unit 18 to the dimming member 3, the thicknesses of the EC layers 32a and 32b, and the ion source type of the electrolyte layer 31, the light transmittance in the dimming member 3 is increased. It is possible to make the state intermediate between the light-shielded state and the transparent state of the color (that is, change the light transmittance arbitrarily).

In the dimming system 100 configured as described above, the dimming control device 1 acquires the amount of solar radiation from the solar radiation sensor 15, acquires the temperature and humidity in the vinyl house 300 from the temperature and humidity sensor 16, and acquires them in chronological order. The light transmittance of the dimming members 3, 3, 3 is adjusted based on the amount of solar radiation and the temperature and humidity. The acquired solar radiation amount and temperature and the adjusted transmittance are output to the external terminal 200 via the network Nw. The external terminal 200 acquires the amount of solar radiation, the temperature, and the transmittance from the dimming control device 1 and displays them on the display unit 212.

The light transmittance is independently adjusted for each dimming member 3, 3, 3 installed in different installation areas according to changes in the amount of solar radiation and changes in temperature and humidity. Therefore, in the first embodiment, the transmittance adjustment coefficient A according to the amount of solar radiation and the temperature and the transmittance adjustment coefficient B according to the installation area of the dimming members 3, 3, 3 are introduced. The dimming control device 1 adjusts the transmittance of the dimming members 3, 3, ... 3 according to the multiplication value of the adjustment coefficient A and the adjustment coefficient B.

FIG. 7 is a chart showing the correspondence between the amount of solar radiation and room temperature and the adjustment coefficient A of the transmittance. FIG. 8 is a chart showing the correspondence between the installation areas of the dimming members 3, 3, ... 3 and the transmittance adjustment coefficient B. In Figure 7, the five stages of the scope of the solar radiation amount from 0.1 kw / m ² to 0.9 kW / m ^2, Yes divided into a 0.1 kw / m ² and less than 0.9 kW / m ² or more, a solar radiation The adjustment coefficient A becomes smaller as the amount is larger. Further, the temperature range is divided into five stages from 0 ° C. to 50 ° C., and less than 0 ° C. and 50 ° C. or higher, and the higher the temperature, the smaller the adjustment coefficient A. The numerical values in FIG. 7 are stored in the storage unit 11 as a table associated with the amount of solar radiation and the temperature. These numbers are examples, and are not limited to these. It is preferable to use a table in which the same or different numerical values as those shown in FIG. 7 are stored according to the humidity.

It is generalized. In FIG. 8, the adjustment coefficient B becomes smaller as the installation area represented by the row number and the column number is closer to the central portion of the roof portion 301. The numerical values in FIG. 8 are stored in the storage unit 11 as a table associated with the row numbers and the column numbers. These numbers are examples, and are not limited to these. It is preferable to use a table in which numerical values that are the same as or different from the numerical values shown in FIG. 8 are stored depending on the object to be irradiated to which the transmitted light of the dimming members 3, 3, ... 3 is irradiated.

In the following, the operation of the dimming control device 1 described above will be described with reference to a flowchart showing the operation. FIG. 9 is a flowchart showing a processing procedure of the control unit 10 for adjusting the light transmittance in the dimming members 3, 3, and 3. FIG. 10 is a flowchart showing a processing procedure of the external terminal 200 that stores the data acquired from the dimming control device 1 in the display memory. FIG. 11 is a schematic view showing a display example in the external terminal 200 according to the first embodiment. The processes of FIGS. 9 and 10 are started at regular intervals (for example, every minute), but the present invention is not limited to this, and the processes may be started irregularly.

M and N in the figure are the number of rows and columns of the installation area of the dimming members 3, 3, ... 3, respectively. Each of m and n is a counter for counting row numbers and column numbers. Here, for example, an agricultural product is targeted for irradiation, and information indicating the object is stored in advance in the storage unit 11. The relationship between the transmittance of the dimming member 3 and the current supplied to the dimming member 3 is stored in advance in the storage unit 11. The adjustment coefficient A and the adjustment coefficient B are simply referred to as the coefficient A and the coefficient B, respectively.

When the process of FIG. 9 is activated by the dimming control device 1, the control unit 10 acquires an image for one frame from the image pickup unit 17 (S11), and the acquired image is externally transmitted via the communication unit 19. Output to the terminal 200 (S12: corresponds to a part of the first output unit). Next, the control unit 10 acquires the amount of solar radiation from the solar radiation sensor 15 (S13), acquires the temperature inside the vinyl house 300 from the temperature / humidity sensor 16 (S14), and obtains the acquired solar radiation amount and temperature in the communication unit 19. Is output to the external terminal 200 via (S15: corresponding to a part of the first output unit). Humidity may be acquired with temperature, and the acquired humidity may be output together with temperature.

After that, the control unit 10 reads the adjustment coefficient A from the table stored in the storage unit 11 according to the acquired amount of solar radiation and temperature (S16). Next, the control unit 10 initializes m to 1 (S17) and further initializes n to 1 (S18) in preparation for reading the adjustment coefficient B.

After that, the control unit 10 reads out an object stored in the storage unit 11 in advance as an irradiation target (S20), and the mth row and nth column from the table stored in the storage unit 11 according to the read object. The adjustment coefficient B of is read out (S21). Next, the control unit 10 calculates the transmittance by multiplying the constant P by the adjustment coefficient A and the adjustment coefficient B (S22), and obtains the calculated transmittance of the dimming member 3 in the mth row and nth column in the communication unit. Output to the external terminal 200 via 19 (S23: corresponding to a part of the first output unit). The constant P may be, for example, an average value of the transmittance on the transparent side shown in FIG. The current values of m and n are added to the transmittance and output.

After that, the control unit 10 adjusts the transmittance of the dimming member 3 in the installation area of the mth row and nth column so as to be the value calculated in step S23 (S24). Next, the control unit 10 increments n by 1 (S25) in order to advance the column number by one, and determines whether or not n becomes N + 1, that is, whether or not n exceeds the number of the last column. (S26).

When n is not N + 1 (S26: NO), the control unit 10 shifts the process to step S20 in order to adjust the transmittance of the dimming member 3 in the next row. On the other hand, when n is N + 1 (S26: YES), the control unit 10 initializes the column number n to 1 (S27), and then increments m by 1 in order to advance the row number by one (S28). ), It is determined whether or not m becomes M + 1, that is, whether or not m exceeds the number of the last line (S29).

When m is not M + 1 (S29: NO), the control unit 10 shifts the process to step S20 in order to adjust the transmittance of the dimming member 3 in the next row. On the other hand, when m is M + 1 (S29: YES), the control unit 10 ends the process of FIG. If it is known that the object is constant in the entire area of the vinyl house 300, the process may be transferred from steps S26 and S29 to step S21.

Next, when the process of FIG. 10 is activated by the external terminal 200, the control unit 210 determines whether or not data has been received from the dimming control device 1 between the time of the previous activation and the present (). In S201), if no reception is performed (S201: NO), the process of FIG. 10 is terminated without executing any special process. When data is received from the dimming control device 1 (S201: YES), the control unit 201 determines whether or not the transmittance has been received (S202), and when the transmittance is received (S202: YES), the reception The transmittance acquired in this manner is stored in the display memory secured in the storage unit 11 (S203), and the process of FIG. 10 is completed. The transmittance is sequentially stored in the display memory according to the values of m and n added at the time of acquisition.

If the transmittance is not received in step S202 (S202: NO), the control unit 210 determines whether or not the amount of solar radiation has been received (S204), and if the amount of solar radiation is received (S204: YES), receives the transmittance. The acquired amount of solar radiation is stored in the display memory (S205), and the process of FIG. 10 is completed. When the amount of solar radiation is not received in step S204 (S204: NO), the control unit 201 determines whether or not the temperature has been received (S206), and when the temperature is received (S206: YES), it has been received and acquired. The temperature is stored in the display memory (S207), and the process of FIG. 10 is completed.

If the temperature is not received in step S206 (S206: NO), the control unit 210 determines whether or not the image data has been received (S208), and if the image data is received (S208: YES), receives and acquires the temperature. The image data is stored in the display memory (S209). The transmittance, the amount of solar radiation, and the temperature stored in the display memory and the image based on the stored image data are displayed on the display unit 212 at a predetermined frame rate. When the process of step S209 is completed, or when the image data is not received in step S208 (S208: NO), the control unit 210 ends the process of FIG.

(Image of cabbage), the transmittance of the dimming members 3, 3, and 3 in rows M and N, and the amount of solar radiation and temperature are displayed. Humidity may be displayed in addition to temperature. For example, a grid showing an imaging area may be displayed on the monitor image in the house. Further, the display of the transmittance is not merely a matrix-like numerical display, but the numerical value of the transmittance may be displayed on the image diagram of the arrangement of the dimming members 3, 3, ... 3.

Therefore, when the amount of solar radiation is excessive, the transmission of solar radiation is suppressed, and when the amount of solar radiation is relatively small, it is possible to effectively take in the solar radiation into the facility.

Further, according to the first embodiment, since the power battery 22 stores the electric power from the solar panels 4, 4 and 4 and supplies the electric power to each part in the own device, the amount of power generated by the solar panels 4, 4 and 4 is increased. It is possible to perform the required control even in the case of rainy weather or cloudy weather, which is significantly reduced.

Further, according to the first embodiment, not only the light transmittance in the dimming members 3, 3, ... 3 is adjusted based on the detected amount of solar radiation, but also the difference in crops is determined based on the temperature in the vinyl house 300. In consideration of this, the light transmittance of the dimming members 3, 3, ... 3 is adjusted. Therefore, it is possible to adjust the transmitted light of solar radiation into the greenhouse 300 to a level suitable for the growth of agricultural products.

Further, according to the first embodiment, the control unit 10 adjusts the light transmittance of the dimming members 3, 3, 3 installed in the plurality of installation areas on the vinyl house 300 for each installation area. As a result, the transmittance of solar radiation into the vinyl house 300 depending on the position in the vinyl house 300 to be irradiated with the transmitted light of the dimming members 3, 3, 3 and the portion having a large shape to be irradiated.

FIG. 13 is a flowchart showing a processing procedure of the control unit 10 that accepts the selection of the irradiation target in the dimming system according to the second embodiment. FIG. 14 is a schematic view showing a display example in the dimming control device 1 according to the second embodiment. The process of FIG. 13 is started at a fixed cycle (for example, every 0.1 seconds), but the present invention is not limited to this, and the process may be started irregularly.

When the process of FIG. 13 is activated by the dimming control device 1, the control unit 10 determines whether or not there is an operation on the operation unit 13 (S41), and when there is no operation (S41: NO). ), The process of FIG. 13 is completed without executing any special process. When there is an operation (S41: YES), it is further determined whether or not the operation is an operation related to the menu selection of the irradiation target (S42). When the operation is an operation related to menu selection (S42: YES), the control unit 10 displays an object selection screen on the display unit 12 (S43), and ends the process of FIG. 13.

If it is determined in step S42 that the operation on the operation unit 13 is not an operation related to menu selection (S42: NO), the control unit 10 determines whether or not the operation is a text box selection operation (S42: NO). S44). When the operation is a text box selection operation (S44: YES), the control unit 10 moves the cursor to the selected text box (S45) and ends the process of FIG. 13.

If it is determined in step S44 that the operation on the operation unit 13 is not a text box selection operation (S44: NO), the control unit 10 determines whether or not the operation is an input operation on the text box.

It is possible to adjust the transmittance of solar radiation inward.

(Embodiment 3)
The second embodiment accepts the selection of the irradiation target to which the transmitted light of the dimming members 3, 3, ... 3 is irradiated, whereas the third embodiment is the monitoring target in the image captured by the imaging unit 17. Is a form in which the recognized object is the irradiation target. Since the block configuration of the dimming control device 1 according to the third embodiment is the same as the block configuration shown in FIG. 1 of the first embodiment, the parts corresponding to the first embodiment are designated by the same reference numerals and the description thereof will be described. Omit.

In the third embodiment, the dimming control device 1 extracts an image of an imaging region corresponding to each installation area of the dimming member 3, 3, 3 from the image captured by the imaging unit 17, and is included in the extracted image. The monitoring target (agricultural product) of is recognized by AI (Artificial Intelligence).

Is a natural number from 1 to N) and is read out as an object in the imaging region. The read object is used for table selection in step S21.

In the following, the operation of the dimming control device 1 described above will be described with reference to a flowchart showing the operation. FIG. 15 is a flowchart showing a processing procedure of the control unit 10 that recognizes the monitoring target in the image in the dimming system according to the third embodiment. FIG. 16 is a schematic diagram showing a content example of the learning model X1 according to the third embodiment. The learning model X1 (corresponding to the first learning model) is included in the learning model X shown in FIG. The process of FIG. 15 is started at a fixed cycle (for example, every day), but the present invention is not limited to this, and the process may be started irregularly. Since the processes of steps S51 to S55 of FIG. 15 are equivalent to the processes of steps S25 to S29 of FIG. 9, the description will be simplified.

When the process of FIG. 15 is activated by the dimming control device 1, the control unit 10 acquires an image for one frame from the imaging unit 17 (S41). Next, the control unit 10 initializes m to 1 (S42) and further initializes n to 1 (S43) in order to start processing from the imaging region of the first row and first column.

After that, the control unit 10 extracts an image of the imaging region in the mth row and nth column from the acquired image (S44: corresponding to the extraction unit), inputs the extracted image into the learning model X1 (S45), and learns. The presence / absence information of detection of the monitoring target is acquired from the model X1 (S46: corresponding to the first acquisition unit).

Here, once moving to FIG. 16, the learning model X1 used in steps S45 and S46 described above uses, for example, a multi-layer convolutional neural network (CNN) learned by deep learning. However, it may be learned by other machine learning. A convolutional neural network has an intermediate layer between the input layer and the output layer. The intermediate layer includes a convolutional layer and a pooling layer composed of a plurality of stages, and a fully connected layer in the final stage. The number of convolution layers, pooling layers and fully connected layers can be appropriately determined.

There are one or more nodes in each of the input layer, intermediate layer and output layer. The nodes of each layer are unidirectionally connected to the nodes existing in the previous and next layers with desired weights and biases. When the data input to the input layer is input to the intermediate layer, the output of one layer is calculated using the activation function including the weight and the bias, and the calculated output is input to the next layer. In the same manner below, the output of the output layer is transmitted to the subsequent layers one after another until the output is obtained.

The learning model X1 takes the pixel value of each pixel constituting the image extracted from the image for one frame as an input, and the probability that the monitoring target exists (that is, with detection) in the input image and none of the monitoring targets exists. The output is the probability (ie no detection). The probability of output by each output node of the output layer is a value of 0 to 1.0, and the total of the probabilities of output by all output nodes is 1.0. The monitoring target here is at least one of agricultural products such as lettuce, tomato, and strawberry. Before inputting an image to the input layer, an appropriate filter including a convolution filter may be applied to the image, and the pixel value of each pixel obtained after applying the filter may be input to the input layer.

The learning model X1 was trained to output detection presence / absence information for each monitoring target when an image is input using teacher data including an image to be monitored and information indicating each type. It is a model. In the learning model X1, data such as coefficients and thresholds of a function that defines a predetermined operation performed on an input value are optimized. The learning model X1 may be downloaded and stored in the storage unit 11 after being learned by a learning device composed of a personal computer, a server computer, or the like, and may be read from a portable storage medium that stores the learning model X1 and stored. It may be stored in the part 11.

Returning to FIG. 15, the control unit 10 determines whether or not the acquired presence / absence information indicates no detection (S47), and if it indicates no detection (S47: YES), stores that the monitoring target is not detected. It is stored in the part 11 (S48). Whether or not to indicate no detection is determined, for example, whether or not the probability of no detection is greater than 0.6. The judgment threshold is not limited to 0.6.

When the presence / absence information does not indicate no detection (S47: NO), the control unit 10 determines whether or not the presence / absence information indicates detection for each monitoring target (S49). When the presence / absence information indicates that the specific monitoring target (agricultural crops such as lettuce, tomato, and strawberry) has been detected (S49: YES), the control unit 10 stores in the storage unit 11 that the specific monitoring target has been detected. (S50). Whether or not to indicate the presence or absence of detection is determined, for example, whether or not the probability of the presence or absence of detection is greater than 0.6. The judgment threshold is not limited to 0.6.

When the processing of step S48 or S50 is completed, or when the presence / absence information does not indicate the presence / absence of detection for any of the monitoring targets in step S49 (S49: NO), the control unit 10 increments n by 1 (S51). , N is determined to be N + 1 (S52). When n is not N + 1 (S52: NO), the control unit 10 shifts the process to step S44 in order to recognize the image in the imaging region in the next row.

On the other hand, when n is N + 1 (S52: YES), the control unit 10 initializes the column number n to 1 (S53), then increments the row number m by 1 (S54), and m becomes M + 1. It is determined whether or not it is (S55). When m is not M + 1 (S55: NO), the control unit 10 shifts the process to step S44. On the other hand, when m is M + 1 (S55: YES), the control unit 10 ends the process of FIG.

According to the processing procedure shown in the flowchart of FIG. 15, it was determined whether or not the monitoring target was detected for each imaging region in the mth row and nth column, but the present invention is not limited to this, and the acquisition is obtained from the imaging unit 17. It may be determined whether or not the monitoring target is detected for the entire image. In this case, steps S42 to S44 and S51 to S55 may be deleted, and the entire image acquired in step S45 may be input to the learning model X1.

As described above, according to the third embodiment, the image extracted from the image in the vinyl house 300 for each imaging area corresponding to the installation area of the dimming member 3, 3, 3 is input to the learning model X1. Based on the detection presence / absence information of the monitoring target (agricultural product) acquired from the learning model X1, the light transmittance is adjusted for each installation area of the dimming members 3, 3, and 3. This makes it possible to finely adjust the light transmittance according to the difference in the monitoring target and the position of the monitoring target.

However, since livestock and seafood move around in the facility, a flowchart similar to that shown in FIG. 15 of the third embodiment is executed, for example, at a cycle of 1 minute to follow the movement of the object.

FIG. 17 is a schematic diagram showing a content example of the learning model X2 according to the modified example 2. The learning model X2 (corresponding to the first learning model) is included in the learning model X shown in FIG. Unlike the learning model X1, the learning model X2 outputs the probability that livestock or seafood such as cows, pigs, and shrimp are present in the input image from the output layer. The learning method and the like of the learning model X2 are the same as those of the learning model X1.

As described above, according to the present modification 2, the light transmittance in the dimming members 3, 3, 3 corresponding to the imaging region is determined according to the movement between the imaging regions of the livestock or seafood to be monitored. adjust. Therefore, it is possible to adjust the transmittance of solar radiation to the destination according to the movement of livestock or seafood.

(Embodiment 4)
The third embodiment is a mode in which the light transmittance of the dimming members 3, 3, ... 3 is adjusted according to the difference in the crops to be monitored, whereas the fourth embodiment is the degree of sunburn of the crops. It is a form in which the light transmittance is adjusted accordingly. Since the block configuration of the dimming control device 1 according to the fourth embodiment is the same as the block configuration shown in FIG. 1 of the first embodiment, the parts corresponding to the first embodiment are designated by the same reference numerals and the description thereof will be described. Omit.

In the fourth embodiment, the dimming control device 1 extracts an imaging region corresponding to each installation area of the dimming member 3, 3, 3 from the image captured by the imaging unit 17, and monitors the extracted image. The degree of sunburn of the target (agricultural product) (hereinafter referred to as the degree of sunburn) is recognized by AI. No sunburn and sunburn degree j (j = 1,2 ... J: J is a natural number of 2 or more) represent the percentage of sunburns from 0 to 1 in ascending order. The dimming control device 1 further calculates the transmittance adjustment coefficient C of the dimming members 3, 3, 3 based on the recognized sunburn degree for each installation area corresponding to the imaging area, and the calculated adjustment coefficient. C is stored in the storage unit 11 as a table of sunburn adjustment coefficients in rows M and N.
