Farm management system
A farm management system 1 for managing an environment of a farm where agricultural produce is grown will be described with reference to fig. 1-fig. 4. The farm management system 1 is a system for supporting cultivation of agricultural produce at a cultivation site C1 (a farm) of a user U1 who is a farmer. The cultivation site C1 may be a farm which is covered by a horticultural installation (e.g., a plastic greenhouse or the like), or it may be a farm on bare ground which is not covered by a horticultural installation.
As shown in fig. 1, the farm management system 1 comprises: a sensor device 10 which is installed at a predetermined position on the cultivation site C1 (e.g., inside a plastic greenhouse, etc.) and acquires environment information inside the cultivation site C1; an information processor 20 for acquiring the environment information and processing said environment information; and an information terminal 30 for displaying display information etc., including the environment information. The sensor device 10, information processor 20 and information terminal 30 are connected by a communication network and are able to inter-communicate. It should be noted that the communication network may be constructed by means of wired communication or wireless communication, and it may be configured by means of wired communication or wireless communication.
As shown in fig. 2, the sensor device 10 comprises: various types of sensors 10a-10d for detecting the environment information (e.g., air temperature, humidity, carbon dioxide concentration, solar radiation, etc.) in the cultivation site C1; and a control device 10e for implementing control to acquire the environment information from the sensors, etc.
The various sensors provided in the sensor device 10 include: a temperature sensor 10a for detecting an air temperature T inside the cultivation site C1; a humidity sensor 10b for detecting humidity F inside the cultivation site C1; a carbon dioxide concentration sensor 10c for detecting a concentration C of carbon dioxide inside the cultivation site C1; and a solar radiation sensor 10d for detecting solar radiation R inside the cultivation site C1. It should be noted that the sensor device 10 may have a configuration comprising some of the types of sensors among the temperature sensor 10a, the humidity sensor 10b, the carbon dioxide concentration sensor 10c and the solar radiation sensor 10d, it may have a configuration comprising various other types of sensors, or it may have a configuration comprising one type of sensor from among the above sensors.
The control device 10e is configured by a microcomputer, etc. comprising a CPU (central processing unit), a ROM (read only memory) and a RAM (random access memory), etc., and is capable of implementing predetermined processing (e.g., transmission processing to send the environment information to the information processor 20, etc.) as a result of various types of programs stored in a memory device such as the ROM being executed by means of the CPU, etc. The control device 10e may be configured by means of dedicated hardware resources and software resources, or it may be configured by means of hardware resources and software resources included in devices other than the sensor device 10, for example.
The control device 10e furthermore comprises: an acquisition unit 10f for acquiring the environment information detected by means of the sensors 10a-10d connected to said control device 10e; an implementation unit 10g for implementing various types of control on the basis of the environment information; and a transmission unit 10h which is controlled by means of the implementation unit 10g in such a way as to send the environment information to the information processor 20. The implementation unit 10g acquires the environment information detected by the various types of sensors from the acquisition unit 10f at preset time intervals (e.g., 10 minutes), and implements transmission processing to send the environment information from the transmission unit 10h to the information processor 20 via the communication network. The sensor device 10 sends the environment information detected by means of the various types of sensors to the information processor 20 as a result of communication processing being carried out by the implementation unit 10g.
The information processor 20 is configured by a computer or the like comprising a CPU, ROM and RAM, etc., and is capable of implementing predetermined processing (e.g., valuable-information processing, display information generation processing and index information generation processing, etc. which will be described later) as a result of various types of programs stored in a memory device such as a ROM being executed by means of the CPU, etc. The information processor 20 may be configured by means of dedicated hardware resources and software resources, or it may be configured by hardware resources and software resources included in the sensor device 10 and the information terminal 30, for example.
As shown in fig. 3, the information processor 20 comprises: an acquisition unit 20a for acquiring the environment information from the sensor device 10 via the communication network; and an implementation unit 20b for implementing various types of processing on the basis of the environment information, etc. Furthermore, the acquisition unit 20a is capable of acquiring weather information which will be described later (e.g., external air temperature, external air humidity, solar radiation, rainfall, etc.) relating to the weather in a region including the cultivation site C1 in which the sensor device 10 is installed, this weather information being acquired from a weather information device 40, which will be described later, via the communication network.
The various types of processing implemented by the information processor 20 include, for example: valuable-information processing for identifying valuable information, which is of value in the cultivation of the agricultural produce at the cultivation site C1, on the basis of information acquired from the information terminal 30 and the weather information device 40, etc.; display information generation processing for generating display information which is displayed on a display device 33 of the information terminal 30 on the basis of the environment information, etc. acquired from the sensor device 10; index information generation processing for generating index information α indicating the extent to which environment information Ie conforms to recommendation information Ir; and future information prediction processing for predicting future changes in the environment information Ie.
In the valuable-information processing, examples of the valuable information include a prediction of the risk of pest damage to the agricultural produce made by the information processor 20 on the basis of a prediction model learned in advance and information acquired from various devices, etc. The risk of pest damage is the risk of an outbreak of pest damage (disease damage, which is damage to the agricultural produce caused by disease, or insect damage, which is damage to the agricultural produce caused by insects). The prediction model may be constructed in accordance with an existing algorithm such as a support vector machine, or it may be a time-series model.
Furthermore, in the display information generation processing, display information to be displayed on the display device 33 of the information terminal 30 is generated and sent to the information terminal 30 via the communication network. The display information includes, for example: primary environment information Ie1 indicating environment information detected by means of the sensor device 10; secondary environment information Ie2 (e.g., saturation deficit, dew point temperature, cumulative temperature, etc.) acquired by means of computation, etc. on the basis of the environment information detected by means of the sensor device 10; recommendation information Ir which is recommended for management of the environment under which agricultural produce is grown at the farm; and the abovementioned valuable information. The primary environment information Ie1 and the secondary environment information Ie2 may, together, be referred to below simply as "environment information Ie". Furthermore, the display information sent to the information terminal 30 by means of the information generation processing includes environment information Ie of a type specified on the basis of input information which is input by means of an input device 31 of the information terminal 30 which will be described later, and the recommendation information Ir corresponding to the type of the environment information Ie.
The recommendation information Ir is information of the same type as the type of the environment information Ie, and is information recommended for management of the environment under which the agricultural produce is grown at the farm. Furthermore, the recommendation information is generated on the basis of theoretical information relating to management of the agricultural produce, and performance information relating to performance at the farm, for example. The theoretical information is set on the basis of documentary information disclosed in documents such as scientific papers, and specialist information recommended by agricultural specialists, etc., for example. Furthermore, the theoretical information may be set by using the documentary information and the specialist information without modification, it may be set by adapting at least a portion of the documentary information or the specialist information, or it may be set by statistically processing the documentary information or the specialist information, for example. Furthermore, an agricultural specialist refers to a person undertaking analysis or research at least relating to appropriate cultivation environments for agricultural produce of the type being cultivated at the farm where the sensor device 10 is installed (e.g., a scientist, researcher or scholar, etc.), or a person having experience over a relatively long period of time (e.g., 5 years, 10 years, etc.) of cultivation of the relevant agricultural produce (e.g., an experienced farmer, etc.), etc. The performance information is set on the basis of environment information acquired at the farm itself or another farm, over a period for which it is considered that the farmer could have performed ideal management. The performance information may be generated, for example, by statistical processing (e.g., averaging at predetermined time intervals (e.g., each hour, etc.)) of the environment information on one or more days on which it is considered that one or more farmers could have performed ideal management. The recommendation information is set on the basis of specialist recommendation relating to management of the agricultural produce.
Furthermore, in the index information generation processing, the extent to which the environment information Ie conforms to the recommendation information Ir is calculated on the basis of a history of the environment information Ie in a predetermined period (e.g., a period from the current time to 24 hours before) and a history of the recommendation information Ir corresponding to said environment information Ie, and the value of this extent is acquired as the index information α.
Furthermore, in the future information prediction processing, environment information Ie at a time ahead of the current time is predicted and acquired as future information. The future information may employ past environment information Ie with similar transitions, the future information may be acquired by means of simulation on the basis of weather information acquired from the weather information device 40, etc., or the future information may be acquired by means of simulation on the basis of treatment performed at the farm where the sensor device 10 is installed (e.g., adjustment of air conditioning by heating equipment, etc., watering, opening/closing of windows or the like, etc.).
The information terminal 30 is configured by a computer, etc. comprising a CPU, ROM and RAM, etc., and is a device which is operable by the user U1 (e.g., a personal computer, a tablet terminal or a smartphone, etc.). The information terminal 30 is capable of realizing predetermined processing (e.g., input processing for receiving input operations by the input device 31 which will be described later, display control processing for causing the display device 33 which will be described later to display the display information, etc.) as a result of various types of programs stored in a memory device such as the ROM being executed by means of the CPU. The information terminal 30 may be configured by means of dedicated hardware resources and software resources, or it may be configured by means of hardware resources and software resources included in the sensor device 10 and the information processor 20, for example.
As shown in fig. 4, the information terminal 30 comprises: an input unit 30a for receiving input operations by the user U1; an acquisition unit 30b for acquiring display information, etc. from the information processor 20; an implementation unit 30c for implementing control of the information terminal 30; and a display unit 20d for displaying the display information. It should be noted that the information terminal 30 may be configured in such a way that it can be carried by the user U1, or it may be configured to be installed at a predetermined location (e.g., inside the plastic greenhouse, etc.) within the cultivation site C1. Furthermore, the input device 31, a control device 32, and the display device 33 may each be configured as separate devices, or they may be configured as a single device.
The input unit 30a receives input operations made by the user U1 and acquires the input operations as input information. The input information which is input by the user U1 includes information indicating the address of the cultivation site C1, the area of the cultivation site C1, the type of agricultural produce, the planting density of the agricultural produce, the cultivation start timing, and the harvesting timing, or a history of application of chemical agents (e.g., agrochemicals, etc.), or switching information for switching the display on the display device 33, etc., for example.
The acquisition unit 30b acquires the input information received by the input unit 30a and the display information generated by means of the information processor 20, and outputs the information to the implementation unit 30c. The implementation unit 32b implements transmission processing to send the input information to the information processor 20, and display control processing for performing control whereby the display information acquired by the acquisition unit 32a is output to the display unit 30d, and the display information is displayed on the display unit 30d.
The display unit 30d is configured by a liquid crystal display or the like, for example, and displays the display information, etc. in a format that is visible to the user U1. Furthermore, as will be described later, display control processing is implemented by means of the implementation unit 30c, whereby the display unit 30d displays, as the display information, the environment information (Ie) at the farm, the recommendation information (Ir) corresponding to the type of environment information generated by means of an information generation device 21, and the index information in a predetermined period, for example. It should be noted that the display unit 30d may be configured by hardware resources and software resources included in the information terminal 30, or it may be configured by means of dedicated hardware resources and software resources.
The weather information device 40 is connected to the communication network to which the information processor 20 is connected, and provides the weather information (e.g., external air temperature, external air humidity, solar radiation, rainfall, etc.) relating to the weather in the region including the cultivation site C1, in accordance with a request from the information processor 20 at any time. It should be noted that the weather information device 40 may be configured as part of the farm management system 1, or it may be configured as a device external to the farm management system 1.
As described above, the farm management system 1 comprises the sensor device 10, the information processor 20, and the information terminal 30 corresponding to the display device according to the present invention. The recommendation information Ir is generated by means of the information processor 20 on the basis of information such as the environment information Ie detected by means of the sensor device 10, and the environment information Ie, the recommendation information Ir corresponding to the environment information Ie, and the index information are displayed in a predetermined visual format on the display unit 30d of the information terminal 30.
It should be noted that in this mode of embodiment, the farm management system 1 has a configuration in which the sensor device 10, the information processor 20, and the information terminal 30 are each provided as separate devices, but the sensor device 10, information processor 20 and information terminal 30 may equally be configured as a single device, or may be configured as two or four or more devices, for example. Furthermore, the various devices and functions provided in the farm management system 1 may be realized by means of software resources or hardware resources, or they may be realized by means of software resources and hardware resources.
Method for controlling display unit of information terminal
A method for controlling the display unit 30d of the information terminal 30 and a display mode on the display unit 30d will be described with reference to fig. 5-fig. 7.
As described above, the information terminal 30 comprises the acquisition unit 30b, the implementation unit 30c, and the display unit 30d, and display control processing is repeatedly implemented by means of the implementation unit 30c at predetermined time intervals (e.g., every 0.01 seconds, etc.), whereby the display information, etc. acquired by the acquisition unit 30b is displayed on the display unit 30d. As shown in fig. 5, display control processing (Sa) includes: display information acquisition processing (Sa01) for acquiring the display information from the information processor 20 of the information terminal 30; display image generation processing (Sa02) for generating display image data for displaying images on the display unit 30d on the basis of the display information; and display mode update processing (Sa03) for updating the display mode on the display unit 30d on the basis of the display image data.
In the display information acquisition processing, the implementation unit 30c first of all acquires, by means of the acquisition unit 30b, input information received by means of the input unit 30a and sends this input information to the information processor 20. At the same time, the type of environment information Ie (e.g., temperature, saturation deficit, etc.) which the user U1 is requesting for display on the information terminal 30 is identified by the information processor 20 on the basis of the input information. The information processor 20 then generates display information including the environment information Ie whereof the type has been identified, recommendation information Ir corresponding to this environment information Ie, and index information α corresponding to this environment information Ie, and the display information is sent to the information terminal 30 via the communication network. After this, the implementation unit 30c acquires, by means of the acquisition unit 30b, the display information sent by means of the information processor 20.
In the display image generation processing, the implementation unit 33b generates, on the basis of the display information acquired by means of the acquisition unit 33a: display image data d1 for displaying the environment information Ie; display image data d2 for displaying the recommendation information Ir corresponding to the type of environment information Ie; display image data d3 for displaying the index information α corresponding to the environment information Ie; and display image data d4 for displaying the future information corresponding to the environment information Ie. The implementation unit 33b furthermore generates: display image data d5 (e.g., a time axis, units of environment information, lines on a graph, etc.) for displaying a graph of the type identified on the basis of the display information; highlighted image data ds1 for performing highlighted display processing to make the environment information Ie at the current time more visible than the environment information Ie at other times; and highlighted image data ds2 for performing highlighted display processing to make the recommendation information Ir corresponding to a time ahead of the current time more visible than the recommendation information Ir at other times.
In the display mode update processing, the implementation unit 30c outputs, to the display unit 30d, the display image data d1-d5 and the highlighted image data ds1, ds2 generated by means of the display image generation processing, and performs control in such a way as to update the display mode on the display unit 30d on the basis of these data items.
An example of the display mode on the display unit 30d which results from implementation of the display control processing will be described next with reference to fig. 6-fig. 8.
As shown in fig. 6, for example, when an input operation for displaying temperature information as the environment information Ie has been received by means of the input unit 30a of the information terminal 30, the display image data d1-d5 is generated on the basis of the display information generated by means of the information processor 20, whereby the following images are each displayed in a superimposed format on the display unit 30d: an image D1 showing transitions of the temperature information detected by means of the sensor device 10 up to the current time; an image D2 showing transitions of recommendation information corresponding to the temperature information (an image showing an upper limit line of a recommended temperature range in this mode of embodiment); an image D3 showing index information αt corresponding to the temperature information; an image D4 showing future predictions of changes in the temperature information; and an image D5 displaying the temperature information on a graph. Additionally, the highlighted data ds1, ds2 is generated on the basis of the display information generated by means of the information processor 20, whereby the following images are each displayed in a superimposed format on the display unit 30d, together with the images D1-D5: an image D6 making the display of the temperature information at the current time more visible (e.g., an image displaying a point indicating the temperature information at the current time larger than other points and also in a flashing mode, etc.); and an image D7 making the display of the recommendation information for the temperature information corresponding to a time ahead of the current time more visible (e.g., an image in which the display of the recommendation information for the temperature information corresponding to a time ahead of the current time is thicker and darker than the display at other times, etc.).
As shown in fig. 7, for example, when an input operation for displaying saturation deficit information as the environment information Ie has been received by means of the input unit 30a of the information terminal 30, saturation deficit information is calculated by the information processor 20 on the basis of the temperature information and humidity information, etc. detected by means of the sensor device 10. The display image data d1-d5 is then generated on the basis of the display information generated on the basis of this saturation deficit information, whereby the following images are each displayed in a superimposed format on the display unit 30d: an image D1 showing transitions of the saturation deficit information calculated up to the current time; an image D2 showing transitions of recommendation information corresponding to the saturation deficit information (a strip-shaped image showing a recommended saturation deficit range in this mode of embodiment); an image D3 showing index information αs corresponding to the saturation deficit information; an image D4 showing future predictions of changes in the saturation deficit information; and an image D5 displaying the saturation deficit information on a graph. Additionally, the highlighted data ds1, ds2 is generated on the basis of the display information generated by means of the information processor 20, whereby the following images are each displayed in a superimposed format on the display unit 30d, together with the images D1-D5: an image D6 making the display of the saturation deficit information at the current time more visible (e.g., an image displaying a point indicating the saturation deficit information at the current time larger than other points and also in a flashing mode, etc.); and an image D7 making the display of the recommendation information for the saturation deficit information corresponding to a time ahead of the current time more visible (e.g., an image in which the display of the recommendation information for the saturation deficit information corresponding to a time ahead of the current time is thicker and darker than the display at other times, etc.).
As shown in fig. 8, for example, when an input operation for displaying the temperature information and the saturation deficit information as the environment information Ie has been received by means of the input unit 30a of the information terminal 30, the display image data d1-d5 relating to the temperature information and the saturation deficit information is generated, whereby the images D1-D5 relating to the temperature information and the images D1-D5 relating to the saturation deficit information are each generated and each displayed in a superimposed format on the display unit 30d, and as a result, the temperature information and the saturation deficit information are displayed on a graph on the same time axis. Additionally, the highlighted image data items ds1, ds2 relating to the temperature information and the saturation deficit information are each generated, whereby the following images are each displayed in a superimposed format on the display unit 30d, together with the images D1-D5: an image D6 making the display of the temperature information and the saturation deficit information at the current time more visible, and an image D7 making the display of the recommendation information for the temperature information and saturation deficit information corresponding to a time ahead of the current time more visible.
