[0010] An environmental management system 1 of this embodiment will be described with reference to the drawings. The embodiment described below is merely an example, and embodiments to which the present invention is applied are not limited to the following embodiment. In all the drawings for explaining the embodiments, the same reference numerals are used for components having the same functions, and repeated explanations will be omitted. Furthermore, in this application, "based on XX" means "based on at least XX," and includes cases where it is based on other elements in addition to XX. Furthermore, "based on XX" is not limited to cases where XX is used directly, but also includes cases where it is based on XX that has been calculated or processed. "XX" is any element (for example, any information).

[0011] [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] [System configuration of Environmental Management System 1] 1 is a diagram showing an example of the device configuration of an environment management system 1 according to this embodiment. The environment management system 1 includes a sensor 10, a server 20, a terminal device 30, and a gateway 40.

[0013] The environmental management system 1 of this embodiment is used in farm fields where crops such as vegetables, fruits, flowers, etc. are cultivated. In the following description, the agricultural worker who uses the terminal device 30 is also referred to as a user U.

[0014] The environmental management system 1 of this embodiment has the following features. (1) By using sensors that can be installed and moved according to the characteristics of each field, it is possible to accurately detect the ambient temperature of the cultivation area in an agricultural greenhouse with a small number of sensors. Therefore, the number of sensors to be installed can be minimized, which is cost-effective. (2) The sensor is battery-powered and wireless, allowing it to be installed freely within the agricultural greenhouse. (3) For proper agricultural management, it is important to continuously collect environmental information inside an agricultural greenhouse over a long period of time. In the present invention, by using multiple sensors that are waterproof and dustproof and have a long battery life due to the frequency of wireless communication, it is possible to continuously collect valid environmental data inside an agricultural greenhouse over a long period of time.

[0015] [Configuration of Sensor 10] The sensor 10 of this embodiment is an example of a sensor that can be installed and moved to suit the characteristics of each farm field as described above. The sensor 10 detects environmental indices within the farm field 5 and outputs the detected environmental indices as detection data D1. The environmental indices include at least one of temperature, humidity, vapor pressure deficit, solar radiation, illuminance, photosynthetic photon flux density, and carbon dioxide concentration. The sensor 10 is preferably configured to be able to simultaneously detect two or more of these environmental indices.

[0016] More specifically, the sensor 10 includes a communication unit 101 , a detection unit 102 , and a power supply unit 103 .

[0017] The communication unit 101 communicates with other devices by short-range wireless communication. In one example of this embodiment, the sensor 10 communicates with the gateway 40 via a first network N1. In this case, the first network N1 is a short-range wireless communication network.

[0018] The detection unit 102 includes various mechanisms and circuits for detecting environmental indices, and detects the environmental indices based on a predetermined sampling period.

[0019] The power supply unit 103 includes a battery (a primary battery or a secondary battery) and supplies power to each unit (for example, the communication unit 101 and the detection unit 102) of the sensor 10. In this embodiment, the power supply unit 103 includes a primary battery.

[0020] The sensor 10 has high waterproof and dustproof performance because it is installed in the field 5. To enhance the waterproof and dustproof performance, the sensor 10 has a structure that makes it difficult for the user U to disassemble or replace the battery. For this reason, the sensor 10 is required to reduce the operating power of the communication unit 101 and the detection unit 102 (i.e., to reduce power consumption).

[0021] A plurality of sensors 10 are installed in the field 5. In this embodiment, when these sensors 10 need to be distinguished, they will be referred to as a first sensor 11, a second sensor 12, ... an n-th sensor 1n (n is a natural number). In this embodiment, when these first sensor 11, second sensor 12, ... an n-th sensor 1n are not to be distinguished, they will be collectively referred to as sensors 10.

[0022] [Example of sensor 10 placement] 2 is a diagram showing an example of the arrangement of the sensor 10 of this embodiment. Hereinafter, when necessary, the explanation will be made using a three-dimensional Cartesian coordinate system in which the plane formed by the x-axis and y-axis indicates the ground surface of the farm field 5 (for example, the agricultural greenhouse 51), and the z-axis indicates the vertical (height) direction.

[0023] A plurality of sensors 10 are installed in various parts of the farm field 5 (especially the agricultural greenhouse 51). Of the sensors 10, a first sensor 11 is installed outside the agricultural greenhouse 51 in the farm field 5. Of the sensors 10, a second sensor 12 to a ninth sensor 19 are installed inside the agricultural greenhouse 51.

[0024] Although the drawing shows that only one first sensor 11 is installed outside the agricultural greenhouse 51, this is not limitative. A plurality of sensors 10 may be installed outside the agricultural greenhouse 51.

[0025] That is, the field 5 includes an agricultural greenhouse 51. Of the multiple sensors 10, two or more sensors 10 are installed inside the agricultural greenhouse 51, and one or more sensors 10 are installed at a position inside the field 5 outside the agricultural greenhouse 51. Note that it is not necessary for a sensor 10 to be installed at a position inside the field 5 outside the agricultural greenhouse 51.

[0026] [Example of sensor 10 placement in the height direction] FIG. 3 is a diagram showing an example of the height arrangement of the sensor 10 of this embodiment. The sensor 10 can be installed at any position in the z-axis direction (i.e., height) within the farm field 5. As an example, FIG. 3 shows a case where the second sensor 12 is installed at a height according to the growth of the crop. Crops have a growing point at the tip of the stem, etc. When cultivating crops, environmental indicators near the growing point may be important. The position of the growing point changes according to the growth of the crop (i.e., with the passage of time). For example, for a certain crop, the growing point z2A in a first period and the growing point z2B in a second period, which is later than the first period, are at different heights. In this case, it is preferable that the second sensor 12 be installed at the position shown as second sensor 12A in the first period and at the position shown as second sensor 12B in the second period.

[0027] The sensor 10 of this embodiment does not require an external power supply because it has a built-in power supply unit 103, can exchange information with external devices via wireless communication, and is waterproof and dustproof, so it can be installed anywhere. In addition, the sensor 10 is designed to be small and lightweight, so the user U can easily change the installation location. Therefore, according to the sensor 10 of this embodiment, the installation position (particularly, the height in the z-axis direction) can be easily changed in accordance with the growth of the crop.

[0028] The sensor 10 may have a function to acquire its installation position. For example, the sensor 10 may have a positioning system such as a global positioning system (GPS), or a system that measures the relative distance to an adjacent sensor 10 based on a difference in communication time between the sensors 10. In this case, the sensor 10 outputs information indicating its own installation position (for example, location information based on x, y, and z coordinates) to the first network N1.

[0029] [About Gateway 40] The gateway 40 is installed in the farm field 5. The gateway 40 aggregates detection data D1 transmitted via a first network N1 from a plurality of sensors 10 installed in the farm field 5, and transmits (i.e., transfers) the data to the server 20 via a second network N2. The second network N2 is, for example, a wired or wireless communication line such as the Internet. The gateway 40 transfers the detection data D1 to the server 20 based on a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol).

[0030] As described above, if the sensor 10 has the function of acquiring its own installation position, the information transferred by the gateway 40 includes the position information of the sensor 10. In this case, the gateway 40 transfers the detection data D1 output by the sensor 10 and the position information to the server 20 for each sensor 10.

[0031] [Server 20 Functional Configuration] The server 20 is a computer device configured as a physical server device, a cloud server, etc. The server 20 includes a communication unit 210, a calculation unit 220, and a storage unit 230.

[0032] The communication unit 210 communicates information with other devices via the second network N2. The calculation unit 220 includes, for example, a central processing unit (CPU), and operates based on programs and data stored in the storage unit 230 to provide various functions. The storage unit 230 is configured by, for example, a hard disk drive or semiconductor memory (flash memory, RAM, ROM), and stores various information such as programs and data read by the calculation unit 220. Note that the storage unit 230 may be realized by a virtual storage device such as a cloud server located outside the server 20.

[0033] The calculation unit 220 includes a detection data acquisition unit 221, a sensor position acquisition unit 222, an occurrence risk calculation unit 223, and an alert presentation unit 224 as its functional units.

[0034] The detection data acquisition unit 221 acquires the detection data D1 received by the communication unit 210 from the sensor 10 via the first network N1, the gateway 40, and the second network N2. As described above, the sensor 10 detects the surrounding environmental indicators based on a predetermined sampling period. The sensor 10 outputs the detected environmental indicators for each sampling period as time-series detection data D1. The detection data acquisition unit 221 acquires the detection data D1 output in time series by the sensor 10, and stores the acquired detection data D1 in the memory unit 230 in time series.

[0035] As described above, the sensor 10 is movably installed in the farm field 5. That is, the detection data acquisition unit 221 acquires detection data D1 of a plurality of sensors 10 movably installed in the farm field 5.

[0036] The sensor position acquisition unit 222 acquires installation position information indicating the installation positions of the plurality of sensors 10 installed in the farm field 5.

[0037] That is, the sensor position acquisition unit 222 acquires the installation position of the sensor 10 for each sensor 10. The sensor position acquisition unit 222 stores the acquired installation position information in the storage unit 230 as sensor position information 231. An example of the sensor position information 231 stored in the storage unit 230 is shown in FIG.

[0038] [About sensor location information] 4 is a diagram showing an example of the sensor position information 231 of this embodiment. The sensor position information 231 is information in which a sensor ID is associated with the position (x coordinate, y coordinate, z coordinate) of each sensor. The sensor ID is an identifier for identifying the sensor 10; for example, the first sensor 11 is assigned sensor ID_1, and the second sensor 12 is assigned sensor ID_2.

[0039] Returning to FIG. 1, the occurrence risk calculation unit 223 calculates the risk of occurrence of crop diseases or pests for each area where the sensor 10 is installed, based on the detection data D1 output by the sensor 10. The alert presentation unit 224 presents an alert to the terminal device 30 when there is an increased risk of crop disease or pest outbreak.

[0040] [Functional configuration of terminal device 30] The terminal device 30 is a computer device such as a personal computer, smartphone, or tablet used by the user U. The terminal device 30 has a wired or wireless communication function and transmits and receives information to and from the server 20 via the second network N2.

[0041] The terminal device 30 includes a communication unit 310 , an operation unit 320 , a display unit 330 , a calculation unit 340 , and a storage unit 350 .

[0042] The communication unit 310 communicates information with other devices via the second network N2.

[0043] The operation unit 320 includes, for example, a keyboard, a mouse, a touch panel, and the like, and detects the operation of the user U. The display unit 330 includes, for example, a liquid crystal display, and displays various images. In the following description, displaying an image by the display unit 330 is also referred to as presenting the image to the user U. Note that presenting broadly includes not only displaying an image, but also printing (printing out) the image, providing information to another device, and the like.

[0044] The calculation unit 340 includes, for example, a central processing unit (CPU), and operates based on programs and data stored in the storage unit 350 to provide various functions. The storage unit 350 is configured by, for example, a hard disk drive or semiconductor memory (flash memory, RAM, ROM), and stores various information such as programs and data read by the calculation unit 340. Note that the storage unit 350 may be realized by a virtual storage device such as a cloud server external to the terminal device 30.

[0045] The calculation unit 340 includes a display control unit 341, a stop operation receiving unit 342, and a registration operation receiving unit 343 as its functional units.

[0046] The configuration and operation flow of each functional unit included in the calculation unit 220 of the server 20 and the calculation unit 340 of the terminal device 30 described above will be described with reference to FIG.

[0047] [Operational flow of Environmental Management System 1] FIG. 5 is a diagram showing an example of the flow of operations of the environment management system 1 of this embodiment. (Step S210) The detection data acquisition unit 221 of the server 20 acquires the detection data D1 from the sensor 10 via the gateway 40. The detection data acquisition unit 221 stores the acquired detection data D1 in the storage unit 230 in chronological order.

[0048] (Step S220) The sensor position acquisition unit 222 acquires the sensor position information 231 stored in the storage unit 230. As an example, the detection data D1 output by the sensor 10 includes a sensor ID. The sensor position acquisition unit 222 searches the sensor position information 231 based on the sensor ID included in the detection data D1, thereby acquiring the position where the sensor 10 from which the detection data D1 was acquired is installed.

[0049] (Step S230) The calculation unit 220 associates the detection data D1 acquired by the detection data acquisition unit 221 with the position information of the sensor 10 acquired by the sensor position acquisition unit 222, and stores them in chronological order in the storage unit 230. Note that in this example, the calculation unit 220 associates the position information of the sensor 10 with the detection data D1 and stores them in the storage unit 230, but this is not limiting. For example, the calculation unit 220 may store only the detection data D1 in chronological order in the storage unit 230, and associate the detection data D1 with the position information when reading out the detection data D1 from the storage unit 230.

[0050] (Step S240) The outbreak risk calculation unit 223 calculates the risk of outbreak of crop disease or pests. If the alert condition is met (for example, if the outbreak risk calculated by the outbreak risk calculation unit 223 exceeds a predetermined threshold), the alert presentation unit 224 notifies the terminal device 30 of an alert.

[0051] (Step S310) The communication unit 310 of the terminal device 30 receives an alert from the server 20. The display control unit 341 causes the display unit 330 to display the received alert.

[0052] (Step S320) The user U operates the operation unit 320 of the terminal device 30. For example, the user U performs an operation to display the detection data D1. The calculation unit 340 of the terminal device 30 performs a predetermined operation based on the user U's operation on the operation unit 320. For example, when the user U performs an operation to display the detection data D1, the calculation unit 340 requests the server 20 to transmit the detection data D1.

[0053] (Step S250) When the calculation unit 220 of the server 20 receives a request to transmit the detection data D1 from the terminal device 30, the calculation unit 220 reads out the detection data D1 from the storage unit 230 and transmits it to the terminal device 30.

[0054] (Step S330) When the display control unit 341 of the terminal device 30 receives the detection data D1 from the server 20, the display control unit 341 causes the display unit 330 to display the received detection data D1. As an example, the display control unit 341 causes the display unit 330 to display a top screen.

[0055] [Top screen configuration example] The top screen includes an alert display screen, a display screen of environmental indicators in the field 5, a display screen of environmental distribution in the field 5, and an action display screen.

[0056] [Screen displaying environmental indicators within the field] The display control unit 341 displays, for example, a current situation display screen P1 as a display screen for environmental indices in the field 5.

[0057] 6 is a diagram showing an example of a current status display screen P1 of this embodiment. The current status display screen P1 is a screen that displays information that integrates detection data D1 output from a plurality of sensors 10 installed in the field 5 managed by the user U. As an example, the current status display screen P1 displays information that integrates detection data D1 output from eight sensors 10 (second sensor 12 to ninth sensor 19) installed in the agricultural greenhouse 51 out of the plurality of sensors 10 shown in FIG. 2.

[0058] As an example, the current status display screen P1 displays the vapor pressure deficit, moving average temperature, average temperature, accumulated temperature, accumulated illuminance, illuminance, CO2 concentration, average humidity, and maximum / minimum temperature within the last 24 hours within the agricultural greenhouse 51. The average value of the environmental indices indicates the sum of the environmental indices detected at multiple installation positions within the agricultural greenhouse 51 divided by the number of installed sensors 10 (i.e., the average value within the agricultural greenhouse 51). The accumulated value of each environmental index indicates the accumulated value of each environmental index since the user U last reset it to zero. Note that the photosynthetic photon flux density may also be displayed on this current status display screen P1.

[0059] [Screen displaying environmental distribution within the field] The display control unit 341 displays, for example, an environmental distribution display screen P2 as a display screen for the environmental distribution in the field 5.

[0060] 7 is a diagram showing an example of the environmental distribution display screen P2 of this embodiment. The environmental distribution display screen P2 is an image that displays the environmental indices indicated by the detection data D1 in a format that makes it easy to visually grasp the correspondence between a map image of the farm field 5 and the installation positions of the sensors 10.

[0061] The map image of the farm field 5 is, for example, an image that represents the farm field 5 and the agricultural greenhouse 51 in the farm field 5 from a bird's-eye view. In the example shown in the figure, the environmental distribution display screen P2 displays the position of the sensor 10 and the environmental index indicated by the detection data D1 detected by the sensor 10 on a map image that represents the agricultural greenhouse 51 from a bird's-eye view using an isometric projection method.

[0062] In the example shown in the figure, the installation positions and detected environmental indices of four sensors 10 are displayed: the third sensor 13 with sensor ID_3 (No. 3), the fifth sensor 15 with sensor ID_5 (No. 5), the seventh sensor 17 with sensor ID_7 (No. 7), and the ninth sensor 19 with sensor ID_9 (No. 9). Displaying the environmental indices detected by the multiple sensors 10 together with their installation positions on the environmental distribution display screen P2, as in this example, can be said to be displaying the distribution of environmental indices within the field 5 superimposed on a map image showing the layout of the field 5.

[0063] That is, the environmental indices in the field 5 indicated by the detection data D1 include at least one of temperature, humidity, vapor pressure deficit, solar radiation, illuminance, photosynthetic photon flux density, and carbon dioxide concentration. The display mode of the environmental distribution display screen P2 displayed on the display unit 330 includes displaying the distribution of environmental indices in the field 5 superimposed on a map image showing the layout of the field 5.

[0064] In this embodiment, the information indicating the distribution of environmental indicators within the field 5 is also referred to as environmental distribution information D2. That is, the environmental distribution information D2 indicates the distribution within the field 5 of at least one of temperature, humidity, vapor pressure deficit, solar radiation, illuminance, photosynthetic photon flux density, and carbon dioxide concentration.

[0065] The display control unit 341 displays the distribution status within the field 5 of at least one of the items of temperature, humidity, sunlight, and saturation indicated by the environmental distribution information D2 as an environmental distribution display screen P2 (environment distribution image).

[0066] [Modified example of environmental distribution display screen] The environment distribution display screen P2 shown in Fig. 7 is an example and is not limited to this. The display control unit 341 can also cause the display unit 330 to display an environment distribution display screen P2a of a modified example.

[0067] 8 is a diagram showing an example of an environmental distribution display screen P2a according to a modified example of this embodiment. On the environmental distribution display screen P2, the numerical values ​​of the environmental indices indicated by the detection data D1 are superimposed on a map image. The environmental distribution display screen P2a according to this modified example differs from the environmental distribution display screen P2 in that the environmental indices indicated by the detection data D1 of each sensor 10 are integrated and displayed on the map image in a display manner such as by changes in brightness, shading, hue, and display density.

[0068] That is, the display manner includes displaying the distribution of environmental indices in at least one manner of changing the brightness, the shade, the hue, or the display density on the map image.

[0069] To summarize the above, the display control unit 341 can be said to display, on the display unit 330 of the terminal device 30, the environmental indicators within the field 5 indicated by the multiple detection data D1 based on the detection data D1 collected by the detection data acquisition unit 221 and the acquired position of the sensor 10, in a display format that visually represents the distribution within the field 5.

[0070] [Action display screen] 9 is a diagram showing an example of an action display screen P3 of this embodiment. The action display screen includes a screen for when the reference value for the action is not exceeded and a screen for when the reference value for the action is exceeded. The action display screen P3 shown in the figure is a screen indicating that the environmental index in the field 5 does not exceed a predetermined reference value (threshold value). The display control unit 341 displays the action display screen P3 based on the alert information D3 transmitted by the alert presentation unit 224 of the server 20.

[0071] The alert presenter 224 of the server 20 generates alert information D3 based on the alert setting information 232 stored in the storage unit 230. An example of the alert setting information 232 is shown in FIG.

[0072] [Alert setting information] 10 is a diagram showing an example of the alert setting information 232 of this embodiment. The alert setting information 232 will be explained using FIGS. 10A to 10C. FIG. 10A is a diagram showing an example of a first part of the alert setting information 232. As shown in FIG. FIG. 10B is a diagram showing an example of the second part of the alert setting information 232. As shown in FIG. FIG. 10C is a diagram showing an example of the second part of the alert setting information 232. As shown in FIG.

[0073] The alert setting information 232 is information that correlates the name of the disease / pest type (alert name), the disease / pest classification, the target crop, the start and end times of the alert, conditions under which the disease / pest is likely to occur (occurrence conditions), notification message, alert message, and proposed actions.

[0074] An alert message is registered for each environmental indicator detected by the sensor 10 and for each condition threshold. The predetermined thresholds include a condition exceeding (first threshold) and a condition warning (second threshold). The condition warning (second threshold) is set lower than the condition exceeding (first threshold). In other words, the condition warning (second threshold) is a threshold indicating a state in which the risk of disease / pest outbreaks is slightly increased. The condition exceeding (first threshold) is a threshold indicating a state in which the risk of disease / pest outbreaks is significantly increased.

[0075] The user U can set, for each alert name (disease / type of pest), whether or not to display the action display screen P3 on the display control unit 341. An example of the alert setting screen P4 displayed by the display control unit 341 is shown in FIG.

[0076] [Alert settings screen] FIG. 11 is a diagram showing an example of the alert setting screen P4 of this embodiment. The alert setting screen P4 is a screen on which the user U sets the type of disease or pest that will generate an alert for the disease or pest that will cause the action display screen P3 to be displayed, out of the types of disease / pest registered in the alert setting information 232. The alert setting screen P4 includes a selection button P41. In the example shown in the figure, the alert setting screen P4 includes a selection button P41a that switches between displaying and hiding vine wilt disease, and a selection button P41b that switches between displaying and hiding powdery mildew. The user U can select the type of disease or pest that will generate an alert by operating the selection button P41.

[0077] [About alert notifications] 12 is a diagram showing an example of a no-alert display screen P5 of this embodiment. As described above, the outbreak risk calculation unit 223 of the server 20 calculates the risk of disease / pest outbreak in the field 5 based on the outbreak conditions registered in the alert setting information 232. If the risk of disease / pest outbreak is equal to or lower than a predetermined threshold, the alert presentation unit 224 does not notify the terminal device 30 of an alert. As a result, the display control unit 341 of the terminal device 30 displays the no-alert display screen P5. The no-alert display screen P5 includes, for example, a message stating, "Currently, there is no special information. All measurement values ​​are within the normal range."

[0078] 13 is a diagram showing an example of a notification message display screen P6 of this embodiment. The occurrence risk calculation unit 223 of the server 20 calculates the risk of disease / pest outbreak in the field 5 based on the outbreak conditions registered in the alert setting information 232. The alert presentation unit 224 notifies the terminal device 30 of an alert when the risk of disease / pest outbreak is higher than a predetermined threshold. As a result, the display control unit 341 of the terminal device 30 displays the notification message display screen P6. The notification message display screen P6 includes a display of "Risk of (type of disease / pest) is increasing (sensor No. xx area)," which is registered in the notification message field of the alert setting information 232.

[0079] That is, the occurrence risk calculation unit 223 calculates the risk of at least one of an epidemic or a pest occurring in the field 5 for each position in the field 5 based on the detection data D1.

[0080] The display control unit 341 displays alert information D3 indicating that the occurrence risk is higher than a predetermined threshold.

[0081] In the example described above, the display control unit 341 displays the alert information D3 indicating that the occurrence risk is higher than a predetermined threshold as a text notification message on the notification message display screen P6, but this is not limited to this. The display control unit 341 may also display the alert information D3 indicating that the occurrence risk is higher than a predetermined threshold as an image in which an image indicating an area where the occurrence risk is higher than the predetermined threshold is superimposed on a map image of the field 5. For example, the display control unit 341 displays the alert distribution display screen P7.

[0082] FIG. 14 is a diagram showing an example of an alert distribution display screen P7 of this embodiment. The alert distribution display screen P7 includes an alert distribution P71. The alert distribution P71 is an example of an image showing areas where the risk of occurrence is higher than a predetermined threshold. In this case, the occurrence risk calculation unit 223 of the server 20 calculates areas where the risk of disease or pest occurrence is high based on environmental distribution information D2 generated based on detection data D1 from each sensor 10 in the field 5. The environmental distribution information D2 is information that indicates the distribution status of the risk of disease or pest occurrence in the field 5 determined based on items detected by the sensors 10. The display control unit 341 displays the alert distribution display screen P7 based on the environmental distribution information D2.

[0083] That is, the environmental distribution information D2 indicates the distribution of the risk of at least one of disease and pest outbreaks in the field 5, determined based on the items detected by the sensor 10. The display control unit 341 displays the distribution of the risk of outbreak indicated by the environmental distribution information D2 as an alert distribution display screen P7 (environmental distribution image).

[0084] That is, the display control unit 341 displays the distribution of the occurrence risk in the field 5 calculated by the occurrence risk calculation unit 223 in a predetermined display mode.

[0085] [Alert details screen] When the notification message display screen P6 is displayed on the display unit 330, and the user U operates the notification message display screen P6, the display control unit 341 of the terminal device 30 causes an alert details screen to be displayed on the display unit 330. The alert details screen includes a warning content display screen P8 and a proposed action display screen P9.

[0086] 15 is a diagram showing an example of the caution content display screen P8 of this embodiment. The caution content display screen P8 is a screen that displays matters that require attention regarding the current state of the field 5 detected by the sensor 10. The display control unit 341 displays the caution content display screen P8 based on information registered in the alert message field of the alert setting information 232.

[0087] There may be cases where the risk of occurrence exceeds a predetermined threshold for multiple types of environmental indicators among the environmental indicators detected by the sensor 10. In this case, the display control unit 341 displays an alert message for each of the environmental indicators whose risk of occurrence exceeds the predetermined threshold.

[0088] 16 is a diagram showing an example of the proposed action display screen P9 of this embodiment. The proposed action display screen P9 is a screen that displays measures (actions) that the user U can take when the risk of an epidemic or pest outbreak is increasing. The display control unit 341 displays information registered in the proposed action column of the alert setting information 232 on the proposed action display screen P9.

[0089] [About the alert stop function] Depending on the user U, if the environment management system 1 issues alerts frequently, the user U may feel annoyed. The environment management system 1 may have a function to stop presenting the alert information D3 based on an operation by the user U.

[0090] That is, the stop operation receiving unit 342 receives an operation to stop the presentation of the alert information D3.

[0091] If an alert is stopped, there is a risk that the user U will forget the response (action) that should have been taken. When an alert stop operation is performed, the display control unit 341 displays the action even if an operation to display the content of the action is not received from the user U.

[0092] That is, when an operation to stop the presentation of the alert information D3 is accepted, the display control unit 341 displays action information D4, which is information indicating an action corresponding to the risk indicated by the alert information D3, on the display unit 330. According to the environment management system 1 configured in this manner, when an alert is stopped, it is possible to ensure that the user U does not forget the action that should be taken.

[0093] [Field sensor status screen] Based on the operation of the user U, the display control unit 341 causes the display unit 330 to display an in-field sensor status screen showing the environmental indices detected by each sensor 10 in the field 5. The in-field sensor status screen is also referred to as a detected data display screen P10.

[0094] 17 is a diagram showing an example of the detection data display screen P10 of this embodiment. The detection data display screen P10 is a screen that shows the current status of the environmental index detected by the sensor 10 selected by the user U from among the sensors 10 installed in the farm field 5. The detection data display screen P10 displays the sensor number (sensor ID) of the sensor 10 selected by the user U, the current time, the measurement item (environmental index), the current measurement value of the environmental index, the result of comparing it with the measurement value of the previous day (a + or - sign and a difference value), etc.

[0095] The detection data display screen P10 may have an operation image (for example, a button image of "display graph") for displaying a graph screen showing the past transition of environmental indices in chronological order. The screen showing the past transition of environmental indices in chronological order is also referred to as a time-series transition display screen P11.

[0096] FIG. 18 is a diagram showing an example of a time series transition display screen P11 of this embodiment. The time series transition display screen P11 is a screen that chronologically displays the transition of past environmental indices. The time series transition display screen P11 displays, for example, a graph of the transition of environmental indices over the past two weeks. It is also possible to switch the period displayed on the time series transition display screen P11 to "1 day," "3 days," "7 days," "14 days," etc. The time series transition display screen P11 displays a graph that is color-coded for each type of environmental index detected by the sensor 10. The time series transition display screen P11 displays a selection image for selecting a display item (measurement item), a selection image for selecting which of the multiple sensors 10 the detection results of which sensor 10 are to be displayed, and the like.

[0097] Displaying the past changes in environmental indices detected by the multiple sensors 10 as a time-series graph can be said to be a display format that visually represents the distribution of environmental indices within the field 5. In other words, the display control unit 341 displays the time-series changes in the environmental indices in a display format that visually represents the distribution within the field 5.

[0098] Action Settings As described above, when there is a high risk of disease or pest outbreaks, the display control unit 341 displays the actions to be taken on the display unit 330. FIG. 19 is a diagram showing an example of the action proposal screen P12 of this embodiment. The action proposal screen P12 displays the management target values ​​of the environmental indicators, information about areas with a high risk of disease or pest outbreaks, and the content of the actions to be taken. These actions can be set by the user U by operating the action setting screen P13.

[0099] 20 is a diagram showing an example of the action setting screen P13 of this embodiment. The action setting screen P13 allows the user to set an action and a target value for the action. The action can be selected from options in an action selection field P14.

[0100] 21 is a diagram showing an example of the action selection field P14 of this embodiment. The action selection field P14 is a screen that displays action candidates (options) in a so-called pull-down menu format. The user U selects a desired action from the action options displayed in the action selection field P14.

[0101] 20, the user U performs an operation to set a target value for the action in the input field for the target value of the action on the action setting screen P13. The registration operation receiving unit 343 receives an operation to register the contents of the action information D4.

[0102] The content of the action may be predetermined. For example, the knowledge of an expert in agricultural crop cultivation (e.g., a veteran farmer) may be stored as action information D4 in the storage unit 230 of the server 20. According to the environment management system 1 configured in this manner, when the user U cultivates a type of agricultural crop that he or she has little experience in cultivating, the user U can take an action based on the knowledge of the expert.

[0103] [User U's account management function] The environment management system 1 may have a function for managing the account of the user U. In this case, the environment management system 1 has a function for managing login accounts and passwords by known means.

[0104] Accounts for operating the terminal device 30 include an administrator authority account and a viewer authority account. The registration operation reception unit 343 (information registration operation unit) receives operations performed by an administrator authority account and rejects operations performed by a viewer authority account.

[0105] According to the environmental management system 1 configured in this manner, it is possible to manage different types of accounts for the manager of the field 5 and the cultivators, thereby preventing erroneous operations such as, for example, a cultivator with little cultivation experience accidentally changing thresholds or action contents.

[0106] [Summary of the embodiment] As described above, the environmental management system 1 of this embodiment includes a plurality of sensors 10 installed in the field 5, a server 20 that accumulates detection data D1 from these sensors 10, and a terminal device 30 connected to the server 20 via a second network N2 (communications network). The terminal device 30 includes a communication unit 310 (data receiving unit) that receives from the server 20 environmental distribution information D2 that indicates the distribution within the field 5 of items that indicate the environment within the field 5 based on the detection data D1 from each sensor 10, and a display control unit 341 that displays, on the display unit 330, an environmental distribution display screen P2 (environment distribution image) indicated by the environmental distribution information D2 received by the communication unit 310 (data receiving unit), superimposed on a position image that indicates the position where the sensor 10 was installed within the field 5.

[0107] According to the environmental control system 1 configured in this manner, it is possible to easily grasp the environmental conditions of the cultivation area.

[0108] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like are also included within the scope that does not deviate from the gist of the present invention. For example, a computer program for implementing the functions of each of the above-described devices may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read and executed by a computer system. Note that the term "computer system" may include hardware such as an OS and peripheral devices.

[0109] In addition, "computer-readable recording medium" refers to writable non-volatile memory such as a flexible disk, optical magnetic disk, ROM, or flash memory, portable media such as a DVD (Digital Versatile Disc), or a storage device such as a hard disk built into a computer system. Furthermore, the term "computer-readable recording medium" also includes those that retain a program for a certain period of time, such as volatile memory (e.g., DRAM (Dynamic Random Access Memory)) within a computer system that serves as a server or client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line.

[0110] The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by transmission waves in the transmission medium. Here, the "transmission medium" that transmits the program refers to a medium that has the function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may also be a program for implementing some of the functions described above, or may be a so-called differential file (differential program) that can implement the functions described above in combination with a program already stored in the computer system.
