[0001] The present invention relates to a measurement device. [Background technology]

[0002] In recent years, in mountainous regions, cultivated land, and other environments, there has been a demand for systems that can easily obtain environmental data related to soil, weather, and water in real time at multiple locations and predict environmental conditions in the near future in order to detect signs of floods and landslides, and to perform irrigation management and yield predictions in farmland. In this regard, conventionally, there has been known technology relating to measuring devices that are installed at locations where environmental data such as temperature, atmospheric pressure, and soil moisture content is to be obtained (see, for example, Non-Patent Document 1 and Patent Document 1).

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-184472 Summary of the Invention [Problem to be solved by the invention]

[0005] However, conventional measurement devices are generally expensive, and installing multiple devices in various environments can be costly. Furthermore, conventional measurement devices have limitations on installation location and height, and because they are heavy, they must be buried deep using strong, dedicated supports to prevent them from falling over, which can make installation and replacement of the measurement device a significant burden. Furthermore, since measurement devices are installed underground or above ground, waterproofing and moisture-proofing measures are important, but conventional technology does not provide appropriate measures, which can result in high labor costs when replacing equipment.

[0006] An aspect of the present invention has been made in consideration of the above circumstances, and aims to provide a measurement device that can acquire environmental data at a lower cost. [Means for solving the problem]

[0007] The measuring device according to the present invention employs the following configuration.

[0008] A first aspect of the present invention is a measuring device comprising: a connecting portion that can be detachably connected to a support portion extending from underground to above; a first sensor that measures conditions on the ground; a communication portion that transmits environmental data measured by the first sensor and a second sensor that measures conditions underground to the outside; a power supply portion that supplies power to the first sensor, the second sensor, and the communication portion; and a storage portion that houses equipment including a control portion that controls at least the communication portion; and a lid portion for opening and closing an opening that allows the equipment to be taken in and out of the storage portion.

[0009] A second aspect of the measuring device of the present invention is further characterized in that the support portion is a rigid polyvinyl chloride pipe or a single-tube pipe, and the connecting portion has a shape that allows it to be supported by the support portion by being inserted into the opening of the rigid polyvinyl chloride pipe or the single-tube pipe.

[0010] In the measurement device according to a third aspect of the present invention, the coupling portion further has an opening through which a cable for transmitting measurement data from the second sensor to the communication portion passes.

[0011] In the measuring device according to a fourth aspect of the present invention, the housing section further houses the equipment in a space other than the upper and lower spaces inside the housing section.

[0012] A measuring device according to a fifth aspect of the present invention further comprises a notification unit that notifies an external device of information according to the state of the device.

[0013] In the measuring device according to a sixth aspect of the present invention, the control unit further adjusts the transmission cycle of the environmental data in accordance with the remaining power level of the power supply unit. [Effects of the Invention]

[0016] Hereinafter, an embodiment of a measuring device of the present invention will be described with reference to the drawings.

[0017] [System Configuration] First, an information providing system 1 to which the measuring device of the embodiment is applied will be described. FIG. 1 is a configuration diagram of the information providing system 1 to which the measuring device of the embodiment is applied. The information providing system 1 shown in FIG. 1 includes, for example, an information providing server 100, multiple measuring devices 200-11 to 200-36, and a terminal device 300. Hereinafter, the multiple measuring devices 200-11 to 200-36 will be collectively referred to as "measuring devices 200" unless they are individually described. The information providing server 100 and the measuring devices 200 can communicate with each other via, for example, a network NW. The network NW includes, for example, the Internet, a wide area network (WAN), a local area network (LAN), a telephone line, a public line, a dedicated line, a provider device, a wireless base station, etc. The network NW may also include a router, a gateway device, or other relay device. In the example of FIG. 1, each measuring device 200 may communicate with another measuring device 200 as a relay device.

[0018] The information providing server 100 acquires environmental data measured by the measuring devices 200 installed in the predetermined areas AR1 to AR3 via the network NW, and analyzes the environmental conditions in the target area corresponding to the area (multiple locations) where the measuring devices 200 are installed based on the acquired environmental data and other information. The target area may be all or part of the predetermined areas AR1 to AR3. Furthermore, the information providing server 100 predicts future environmental changes based on the analysis results.

[0019] For example, the information providing server 100 analyzes environmental conditions, including soil conditions, in a target area. Examples of soil conditions include at least one of soil moisture content, soil pH, redox potential, groundwater level, groundwater temperature, and the direction of soil moisture movement. The environmental conditions may also include the condition of the ground (air) and the condition of plants, such as agricultural crops and forests, growing in the target area. The analysis of this information may include not only environmental data but also information acquired from external devices (e.g., future weather information) and information obtained from map information (e.g., soil hardness information and geological layer information). For example, when the soil moisture content (more specifically, the soil volumetric water content) is below a threshold, the information providing server 100 analyzes that there is a water shortage for agricultural crops or that irrigation is necessary. Furthermore, when the soil moisture content exceeds an upper limit, the information providing server 100 predicts that a disaster, such as a flood or a landslide (slope collapse), may occur (or has occurred).

[0020] The information providing server 100 also analyzes time-series environmental conditions and predicts future (predetermined time-lapse) environmental conditions in the target area based on the results of the time-series analysis. For example, the information providing server 100 predicts the need for and timing of irrigation in the target area based on environmental data, the topography of the target area, and soil hardness information of the target area. The information providing server 100 may also predict the degree of future change in soil moisture content in the target area based on past or future weather information. The information providing server 100 may also predict the occurrence of future (predetermined time-lapse) disasters (e.g., slope failures such as landslides, floods, droughts) in the target area based on environmental data, the topography of the target area, and soil hardness information of the target area. The information providing server 100 may also predict the direction of soil moisture movement in the target area and generate information for proposing soil improvement based on the prediction results.

[0021] Furthermore, the information providing server 100 generates information (for example, images or sounds) to be provided to users such as administrators based on the analysis results, prediction results, etc., and outputs the generated information to the terminal device 300 or a display unit of the information providing server 100. Note that the information providing server 100 may function as a cloud server that communicates with the measuring device 200 and the terminal device 300 via a network NW and transmits and receives various data.

[0022] The measuring device 200 measures surrounding environmental data. The environmental data may include, for example, conditions on the ground (air), underground, and underwater, as well as the conditions of plants such as agricultural crops and forests growing in the target area. For example, the environmental data may include various information such as the ambient temperature (air temperature, soil temperature, water temperature), humidity, atmospheric pressure, soil moisture (groundwater), groundwater level, and precipitation. The environmental data may also include information on solar radiation, wind direction, wind speed, amounts of dust, pollen, and PM2.5, detected gases and odors (for example, the odors of substances volatilized from plants and animals (including insects and microorganisms) in farmland and forests, the odor of compost spread on farmland, etc.), and images from infrared cameras and fixed-point cameras. The measuring device 200 is equipped with various sensors for measuring the environmental data information described above. The various sensors may be installed at a predetermined height above ground (which may be one location or multiple locations), at a predetermined depth underground (which may be one location or multiple locations), or both above ground and underground.

[0023] Furthermore, the measuring device 200 includes a communication unit for transmitting the environmental data measured at a predetermined interval to the information providing server 100 via the network NW, and a power supply unit such as a battery (power storage unit) or cell for supplying power to each device in the device. If a battery is provided, the measuring device 200 may be provided with a mechanism for storing power obtained by energy harvesting from sunlight, wind power, electromagnetic waves, etc. in the battery. The environmental data may also include information regarding the amount of power in the battery in the measuring device 200. The measuring device 200 may also be provided with a position sensor for acquiring position information (latitude and longitude). The position sensor is, for example, a sensor that can detect latitude and longitude using a Global Navigation Satellite System (GNSS). Details of the measuring device 200 will be described later.

[0024] In the information providing system 1 according to the embodiment, for example, different numbers (installation densities) or types of measuring devices 200 are installed depending on the topography and area condition information (for example, information on features such as paddy fields, farmlands, pastures, roads, buildings, mountains, rivers, and oceans). The installation densities and types are managed in advance by the information providing server 100 or the like. In the example of FIG. 1 , area AR1 is a forest area, area AR2 is a pasture area, and area AR3 is a paddy field area. Measuring devices 200-11 to 200-13 capable of measuring at least one of soil composition, soil temperature, precipitation, air temperature, solar radiation, groundwater temperature, and groundwater level are installed in area AR1. Measuring devices 200-21 to 200-25 capable of measuring at least one of soil composition, soil pH (an index value indicating the acidity or alkalinity of soil), precipitation, air temperature, and air temperature are installed in area AR2. Area AR3 is installed with measuring devices 200-31 to 200-36 that can measure, for example, at least one of leaf color, plant color (to detect changes due to fertilizer deficiency or pest damage), soil pH, oxidation-reduction potential, solar radiation, air temperature, water temperature, water level, etc. These measuring devices 200 do not need to measure the same environmental data individually, and it is sufficient if multiple measuring devices 200 can measure the various environmental data described above.

[0025] The terminal device 300 may be, for example, a tablet terminal or a smartphone, or may be a general-purpose PC (Personal Computer), a server device, or the like. The terminal device 300 includes, for example, a communication unit for communicating with the outside via the network NW, a display unit for displaying images (including moving images), an audio output unit for outputting audio, and a reception unit for receiving user input. The terminal device 300 accesses the information providing server 100 via the network NW and acquires information such as environmental data collected by the information providing server 100 from the measuring devices 200, analysis results based on the environmental data, and prediction results of future environmental changes. For example, the terminal device 300 can visualize, on the web, environmental data centrally managed by the information providing server 100, analysis results of the environmental data, and prediction results of environmental conditions. In this way, a web-based system configuration can be applied, eliminating the need for dedicated software in the terminal device 300 and improving user convenience. Note that the information providing system 1 may include multiple terminal devices 300.

[0026] [Measuring Device] Next, the details of the measuring device 200 of the embodiment will be specifically described. Fig. 2 is a diagram showing an example of the configuration of the measuring device 200. The measuring device 200 includes a container body 202 and a lid 204. In addition to the above configuration, the measuring device 200 may also include a support (base) 206. The container body 202 is an example of a "container."

[0027] The container body 202 is formed, for example, in a cylindrical shape, and has openings (described later) on the top and bottom surfaces. The upper and bottom ends of the container body 202 are provided with notches (described later) and connecting portions 202a. The top opening of the container body 202 can be opened and closed by fitting, engaging, or screwing with a detachable lid 204. The container body 202 can be fixed (joined) by fitting, engaging, or screwing its bottom end with the top end of a support portion 206, and is detachably supported by the support portion 206. The support portion 206 is fixed to the target location by burying its bottom in the ground UG, and supports the container body 202 connected at its top end. The measuring device 200 may not have the support portion 206. In this case, the portions of the measuring device 200 other than the support portion 206 are attached to other members (for example, a building pillar or a fence).

[0028] The container body 202 and the lid 204 are made of a synthetic resin such as polyvinyl chloride, more specifically, acrylonitrile-styrene-acrylate (ASA) resin, but may be made of other materials. The support 206 is made of, for example, a hard polyvinyl chloride pipe or a single-tube pipe, but may be made of other materials. The container body 202 and the lid 204 may be formed using, for example, a 3D printer or injection molding.

[0029] Furthermore, the container body 202 and the support part 206 are formed cylindrically, which reduces the effects of surrounding wind, etc. Furthermore, the container body 202 and the support part 206 are configured to be detachable via the connecting part 202a, which makes replacement work by workers easy, and furthermore, since the support part 206 can be used as is (as installed) even when replacing the container body 202, equipment costs can be reduced compared to an all-in-one device.

[0030] In the example of FIG. 2, the measuring device 200 contains, for example, devices including a battery 210, a communication unit 220, a control unit 230, a first sensor 240, and a second sensor 250. Note that the measuring device 200 does not necessarily contain either the first sensor 240 or the second sensor 250. The measuring device 200 may also contain a memory (storage unit) 260 that temporarily stores information from the first sensor 240 and the second sensor 250 and stores programs and control information (log information, etc.). These components (devices) are included in the measuring device 200. These components are connected by cables or the like. The control unit 230 is realized, for example, by a hardware processor such as a CPU (Central Processing Unit) executing a program (software). The control unit 230 may be realized by hardware (including circuitry) such as a large-scale integration (LSI), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a graphics processing unit (GPU), or may be realized by a combination of software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transitory storage medium) such as a hard disk drive (HDD) or flash memory, or may be stored in a removable storage medium (a non-transitory storage medium) such as a DVD or CD-ROM, and installed in the storage device of the measuring device 200 by inserting the storage medium into a drive or the like. The storage device is, for example, the memory 260. The battery 210 is an example of a "power supply unit."

[0031] The battery 210 supplies power to the communication unit 220, the control unit 230, the first sensor 240, the second sensor 250, and the memory 260. The battery 210 is, for example, a secondary battery such as a lithium ion battery or a capacitor, but is not limited to these. Furthermore, if the measuring device 200 is provided with an energy harvester such as a solar panel, the battery 210 may store power obtained by the energy harvester.

[0032] The communication unit 220 may communicate with the information providing server 100 via the network NW, or may wirelessly communicate with other measurement devices based on, for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), or other short-range wireless communication standards. For example, under the control of the control unit 230, the communication unit 220 transmits environmental data measured by the first sensor 240 and the second sensor 250 to the outside via wireless communication or the like.

[0033] The control unit 230 controls all of the components of the measuring device 200. The control unit 230 temporarily stores the environmental data measured by the first sensor 240 and the second sensor 250 in the memory 260, and controls transmission of the environmental data to the information providing server 100 at predetermined intervals via the communication unit 220. When transmitting the environmental data, the control unit 230 may add, to the environmental data, identification information of the measuring device (device ID), identification information of the sensor, time information based on an internal clock, location information acquired from a location sensor, etc. The control unit 230 may also erase the information stored in the memory 260 at a predetermined timing (for example, when transmission to the information providing server 100 is completed).

[0034] The first sensor 240 is a sensor for mainly measuring terrestrial environmental data, and may include, for example, at least one of a temperature sensor, humidity sensor, air pressure sensor, wind sensor, rainfall sensor, solar radiation sensor, odor detection sensor, camera sensor, image discrimination sensor, infrared / near-infrared sensor, water temperature sensor, water level sensor, etc. The first sensor 240 may also include a position sensor. The second sensor 250 is a sensor for measuring underground UG environmental data, and may include, for example, at least one of a soil temperature sensor, a soil component (e.g., soil moisture, soil pH, redox potential) sensor, groundwater temperature sensor, groundwater level sensor, etc. The first sensor 240 may be installed at one or more heights where terrestrial environmental data is desired to be measured, and the second sensor 250 may be installed at one or more depths where underground UG or underwater environmental data is measured.

[0035] Note that some or all of the equipment installed inside the measuring device 200 is installed by being inserted through an opening in the top surface of the container body 202 with the lid 204 open. The battery 210, communication unit 220, control unit 230, first sensor 240, and memory 260 installed on the container body 202 side are arranged so that predetermined spaces FS1 and FS2 are provided above and below inside the main body. In other words, the equipment housed in the container body 202 is not placed in the upper and lower spaces FS1 and FS2, respectively, but is housed in a space other than the spaces FS1 and FS2. By providing the spaces FS1 and FS2, it is possible to suppress deterioration of the equipment due to the influence of moisture inside the container, etc., and to improve the availability of the equipment.

[0036] In the embodiment, the installation density and type of the measuring devices 200 are varied depending on the type of terrain and feature. For example, the installation density or type of the measuring devices 200 is varied depending on whether the terrain is sloping (the inclination of the ground relative to the horizontal is a predetermined angle or more) or flat (the inclination of the ground relative to the horizontal is less than a predetermined angle). When the terrain is sloping, water levels and groundwater change rapidly, causing water to move from the top of the slope to the bottom. Therefore, the number of measuring devices 200 is increased in order to grasp the water movement status. Furthermore, when the terrain is flat, the sunshine hours are longer than on a slope, so sensors that can measure air temperature and soil temperature are used. Furthermore, when the feature is a rice paddy, a sensor that measures the water level of the rice paddy is provided instead of (or in addition to) a sensor that measures the groundwater level. Furthermore, when a combination of different terrains (e.g., a flat area below a slope) is expected to be more susceptible to damage such as flooding, the installation density of the measuring devices 200 is narrower (more devices are installed) than in other flat areas. In this way, by measuring the installation density and type of measuring devices 200 according to the topography and types of features in the area, more appropriate environmental data can be obtained.

[0037] [Measuring device shape] Next, the shape of the measuring device 200 according to the embodiment will be specifically described with reference to the drawings. Fig. 3 is a diagram for explaining the shape of the measuring device 200. The example in Fig. 3 shows a state in which the container body 202, the lid 204, and the support 206 are removed.

[0038] 3, a coupling portion 202a is provided at the bottom of the container body 202 of the measuring device 200. The coupling portion 202a may be formed integrally with a housing portion that houses the equipment inside the container body 202, or may be formed separately and joined to the housing portion. The coupling portion 202a has a shape that allows the container body 202 and the support portion 206 to fit together by being inserted into the support portion 206 (hollow portion) through an opening OP1 of the support portion 206. For example, the outer diameter D1 of the coupling portion 202a is formed slightly smaller than the inner diameter D2 of the support portion 206 so that the outer surface of the coupling portion 202a contacts the inner surface of the support portion 206.

[0039] 3, by making the outer diameter D3 of the container body 202 (portions other than the coupling portion 202a) larger than the outer diameter D1 of the coupling portion 202a, after the coupling portion 202a is inserted through the opening OP1 of the support portion 206, the container body 202 is supported by the upper surface (upper end) of the support portion 206 due to the unevenness when the coupling portion 202a is inserted up to a height H1 of the coupling portion 202a. Note that the higher the height H1, the larger the contact area with the inner surface of the support portion 206, and therefore the greater the frictional force during attachment and detachment, and the greater the degree of attachment. Therefore, a container body 202 with a different height H1 may be used depending on the environment in which the measuring device 200 is installed. For example, when the measuring device 200 is installed in a location with a slope (where the ground is inclined at a predetermined angle or more relative to the horizontal), a container body with a higher height H1 is used compared to when the measuring device 200 is installed in a flat location (where the ground is inclined at a predetermined angle or less relative to the horizontal). Furthermore, when installing in a water-rich location such as a rice paddy, a container body 202 with a higher height H1 than when installed in other locations is used to make it difficult for water to enter the interior through the joints. The outer surface of the connecting portion 202a may be formed with a shape for engaging or screwing with the inner surface of the support portion 206.

[0040] The above-described configuration of the connecting portion 202a allows workers to easily attach and detach the support portion 206 and the container body 202, thereby reducing the labor costs involved in replacement and the like.

[0041] Furthermore, an upper surface opening UO is provided at the top of the container body 202 for inserting and removing devices such as the battery 210, communication unit 220, control unit 230, first sensor 240, and memory 260 into and from the container. The measuring device 200 is also provided with a lid 204 for opening and closing this upper surface opening UO. An inner diameter D4 of the lid 204 is larger than an outer diameter D3 of the container body 202, and protrusions 204b are provided on the inner surface of the lid 204. Furthermore, notches (or grooves) 202b corresponding to the positions and number of the protrusions 204b are provided on the upper side of the container body 202. Note that, in the example of FIG. 3, two protrusions 204b-1 and 204b-2 and two corresponding notches 202b-1 and 202b-2 are provided, but the number and shape are not limited to those of the example of FIG. 3.

[0042] Furthermore, when closing the top opening UO with the lid portion 204, the lid portion 204 is moved downward so that the protrusions 204b-1 and 204b-2 are inserted into the notches 202b-1 and 202b-2 provided on the upper side of the container body 202, and then the lid portion 204 is rotated or otherwise moved to conform to the shapes of the notches 202b-1 and 202b-2, thereby engaging the lid portion 204 with the top of the container body 202. Note that, contrary to the example of FIG. 3 , protrusions may be provided on the container body 202 and notches (or grooves) may be provided on the lid portion 204. With the above-described configuration, the top opening UO can be covered and fixed with the lid portion 204, thereby reliably closing the top. Furthermore, when opening the lid portion 204, the lid portion 204 can be removed from the container body 202 and the top opening UO can be opened by performing the reverse operations to those used when closing the lid portion 204.

[0043] In the embodiment, a rubber sealing member may be provided on the lid 204 at a portion that comes into contact with the upper surface of the container body 202. The sealing member may also be provided on the upper surface of the container body 202, or on both the lid 204 and the container body 202. This can further improve airtightness and waterproofing, and can suppress deterioration of devices housed inside the body.

[0044] In addition, in the embodiment, a partition member PP may be provided inside the container body 202 to prevent the devices housed in the spaces FS1 and FS2 from being placed therein, and a mark MK or the like may be provided to indicate the division of the space. The partition member PP may be formed, for example, in a mesh shape or have an opening in a portion thereof to allow cables for communicating environmental data or supplying power to pass through. The marker MK indicating the division of the space may be drawn in a predetermined color, or may have grooves or protrusions. Cushioning members, waterproof (moisture-proof) members, or the like may be provided in the spaces FS1 and FS2 to prevent the installation of devices therein. This prevents devices from being placed in the spaces FS1 and FS2, and prevents the devices from deteriorating due to the effects of moisture inside the container.

[0045] 3, an opening BO is provided on the bottom surface of the container body 202 (the bottom surface of the connecting portion 202a) to supply power to the second sensor 250 and to pass a cable for acquiring measurement data from the second sensor 250. In the example of FIG. 3, two circular openings BO1 and BO2 are provided, but the number, shape, size, and position of the openings BO are not limited to those in the example of FIG. 3. An opening / closing mechanism that can open and close the opening BO may be provided.

[0046] FIG. 4 is a diagram illustrating the opening / closing mechanisms of the openings BO1 and BO2. The example in FIG. 4 shows the vicinity of the lower portion of the container body 202 (joint portion 202a). In the example in FIG. 4, opening / closing mechanisms 202c-1 and 202c-2 are provided in the openings BO1 and BO2, respectively. The opening / closing mechanisms 202c-1 and 202c-2 are attached to the openings BO1 and BO2, for example, by screwing or engaging. The opening / closing mechanisms 202c-1 and 202c-2 open and close the openings BO1# and BO2# provided in the opening / closing mechanisms 202c-1 and 202c-2 by rotating them in a predetermined direction about their central axes. For example, the diameters of the openings BO1# and BO2# are reduced by rotating the opening / closing mechanisms 202c-1 and 202c-2 clockwise, and the diameters of the openings BO1# and BO2# are increased by rotating them counterclockwise.

[0047] 3, it is possible to prevent water from entering the container body 202 from the outside. Furthermore, by reducing the diameter of the openings BO1# and BO2# after the cables have been passed through, it is possible to fix the cables and improve airtightness.

[0048] [Variations] In the embodiment, the container body 202 is not limited to a cylindrical shape. For example, at least a portion of the container body 202 may be tapered so that the outer diameter decreases toward the bottom. FIG. 5 is a diagram illustrating a modified example of the container body. In the example of FIG. 5, the container body 202d is tapered so that the outer diameter decreases from the top to the bottom (in the example of FIG. 3, the outer diameter D10 gradually decreases to the outer diameter D11). The outer diameter D11 is smaller than the inner diameter D3 of the support portion 206, and the outer diameter D10 is larger than the inner diameter D3. This facilitates insertion when the container body 202d is inserted into and coupled to the opening OP of the support portion 206 due to the small diameter at the bottom, thereby reducing the installation burden. Furthermore, because the outer diameter D10 is larger than the inner diameter D3 of the support portion 206, the container body 202e is prevented from entirely entering the cavity of the support portion 206, and can be reliably fixed (supported). The container body 202 may also be formed in a polygonal shape.

[0049] Furthermore, in the embodiment, the measuring device 200 may be provided with a notification unit that notifies the outside of the state of the housed device in addition to the devices shown in FIG. 2 described above. FIG. 6 is a diagram showing an example of a measuring device 200A that includes a notification unit. The measuring device 200A is provided with notification units 270-1 and 270-2 in addition to the configuration of the measuring device 200 shown in FIG. 2, for example. The notification unit 270-1 is a light-emitting unit such as an LED (Light Emitting Diode) that emits light of a predetermined color toward the outside (surroundings). The notification unit 270-2 is a speaker or the like that outputs a predetermined sound (for example, an alarm sound) to the outside (surroundings).

[0050] For example, the control unit 230 causes the notification unit 270-1 to output a color corresponding to the remaining power level of the battery 210 (to light or blink the light-emitting unit). Furthermore, when the control unit 230 detects that an abnormality has occurred in the first sensor 240 or the second sensor 250, the control unit 230 causes the notification unit 270-1 to output a color indicating that an abnormality has occurred. Furthermore, when the control unit 230 determines that an abnormality has occurred based on information acquired from the first sensor 240 or the second sensor 250, the control unit 230 may cause the notification unit 270-2 to output a sound indicating that an abnormality has occurred. Note that when a sound is output, the volume, type of sound, frequency at which the sound is output, and the like may be adjusted according to the external environment. Furthermore, the notification unit 270 may notify identification information (device ID) of the measurement device 200A.

[0051] This allows, for example, a worker performing maintenance such as replacing or repairing the measuring device 200 to more accurately understand the status of the measuring device 200. This allows the maintenance work to be performed efficiently and reduces work costs. Note that the installation positions, number, shape, etc. of the notification units 270-1 and 270-2 are not limited to the example in FIG. 6. Note that when the control unit 230 determines that an abnormality has occurred, the communication unit 220 may transmit information indicating the abnormality together with the position information of the measuring device 200 to the information providing server 100, the terminal device 300, etc.

[0052] In the embodiment, the measuring device 200 may be provided with a power generation mechanism. FIG. 7 is a diagram illustrating an example of the power generation mechanism in the embodiment. In the example of FIG. 7, a solar panel 280 is provided on the upper surface of the lid 204 of the measuring device 200. The solar panel 280 is an example of a "power generation unit." The solar panel 280 acquires solar energy from the outside and supplies the generated electricity to the battery 210 for storage. For example, the measuring device 200 is likely to be installed in a location that is easily exposed to sunlight, such as a rice field or paddy field. Therefore, by providing a power generation unit such as the solar panel 280 in the measuring device 200 that is installed in a location that is easily exposed to sunlight, it is possible to improve the operating rate and reduce the number of maintenance tasks, such as battery replacement, thereby reducing labor and operating costs.

[0053] The solar panel 280 may be installed on the side surface of the container body 202 instead of (or in addition to) the top surface of the lid 204 .

[0054] When transmitting environmental data to the information providing server 100, the control unit 230 may adjust the transmission cycle of the environmental data according to the remaining power of the battery 210. For example, when the remaining power falls below a threshold, the control unit 230 lengthens the transmission cycle from a normal cycle (reference cycle). Furthermore, the control unit 230 may lengthen the transmission cycle as the remaining power decreases. This makes it possible to reduce power consumption and operate the measuring device 200 for a long time. Furthermore, after lengthening the transmission cycle, if the remaining power increases due to the solar panel 280 or the like provided on the measuring device 200, the control unit 230 may shorten the transmission cycle in accordance with the increased remaining power. This makes it possible to acquire more environmental data while maintaining an improved operation rate.

[0055] [Example of measurement device installation] Next, an example of installation of the measuring device 200 will be described with reference to the drawings. Note that, although the following describes several examples of installation, the present invention is not limited to the examples described below.

[0056] (First Example) FIG. 8 is a diagram illustrating an example of installation of the measuring device 200 in the first embodiment. The first embodiment illustrates an example in which the measuring device 200 is installed in a grazing (raising) area 400 for cows (an example of livestock). Specifically, one or more measuring devices 200a are attached at predetermined intervals to a fence 410 that separates the grazing area 400, and one or more measuring devices 200b are attached at predetermined intervals to pillars of a cowshed 420. A compost shed may be installed in the grazing area 400, and one or more measuring devices 200b may also be attached to pillars, etc., in the same way as in the cowshed 420. The measuring devices 200b include measuring devices 200b1 and 200b2 at different heights on the same pillar. The cowshed 420 is also provided with one or more atomizers 422, sprinklers 424, electric fans 426, etc.

[0057] Measuring device 200a is provided with, for example, an odor sensor and a wind direction sensor, and measures the surrounding odor (odor intensity) and wind direction (which may include wind volume) at a predetermined cycle. Measuring devices 200b1 and 200b2 are each provided with an odor sensor and a temperature sensor, and measure the surrounding odor (odor intensity) and temperature at a predetermined cycle.

[0058] The information providing server 100 acquires information (environmental data) obtained by the measuring devices 200a, 200b1, and 200b2 and analyzes the environmental conditions in the grazing area 400. The information providing server 100 can also generate images showing the spatial distribution of the environmental conditions in the grazing area 400 and provide the user with these images. For example, the information providing server 100 can generate images showing the spatial distribution of odors and wind direction in the grazing area 400 analyzed using the environmental data from the measuring devices 200a and 200b of the first embodiment, or images showing the spatial distribution of temperature near the cowshed, and provide these images to the user. Furthermore, when the information providing server 100 acquires the operating status of various devices (such as the atomizer 422, sprinkler 424, and electric fan 426) installed in the grazing area 400, it may generate images showing the operating status and provide these images to the user.

[0059] According to the first embodiment, by using the environmental data measured by the measuring devices 200a and 200b, a more suitable environment can be realized, taking into consideration the surroundings of the grazing area 400, the health of the cows, measures against heat, etc.

[0060] (Second Example) FIG. 9 is a diagram illustrating an example of installation of a measuring device 200 in a second embodiment. The second embodiment shows an example in which a measuring device 200 is installed in a mountain stream (stream) area 500. Specifically, one or more measuring devices 200c are installed at a predetermined interval in the mountain stream portion, and one or more measuring devices 200d are installed at a predetermined interval on both sides of the mountain stream. The measuring device 200c is provided with, for example, a water level sensor and a turbidity sensor, and measures the water level and turbidity at the installation point at a predetermined cycle. The measuring device 200d is provided with, for example, two soil moisture sensors at different heights (two depth levels), and measures the soil moisture at the installation point at a predetermined cycle.

[0061] The information providing server 100 acquires information (environmental data) obtained by the measuring devices 200c and 200d, analyzes the environmental conditions in the mountain stream area 500, generates an image showing the spatial distribution of the environmental conditions, and provides it to the user. For example, the information providing server 100 generates a soil moisture map (for shallow and deep water) analyzed from the information obtained from the measuring device 200d in accordance with the installation positions of the measuring devices 200c and 200d, and information showing changes in water level and turbidity analyzed from the information obtained from the measuring device 200c according to the installation position of the measuring device 200c (water level-turbidity map), and provides it to the user.

[0062] According to the second embodiment, by using the environmental data measured by the measuring devices 200c and 200d, the user can more accurately grasp the spatial distribution of soil moisture, water level, and turbidity in the event of a landslide caused by a thunderstorm, etc. This allows the user to take appropriate preparations and measures in preparation for a disaster.

[0063] (Third Example) FIG. 10 is a diagram illustrating an example of installation of a measuring device 200 in a third embodiment. The third embodiment shows an example in which a measuring device 200e is installed in an irrigation channel area 600. In the example of FIG. 10, one or more measuring devices 200e are installed at predetermined intervals in an irrigation channel 620 through which rainwater, water from a river 610, etc. flows. The measuring device 200e may be installed near a water intake position 621 from the river 610. The measuring device 200e is provided with, for example, a water level sensor and a flow velocity sensor, and measures the water level and flow velocity at the installation point at a predetermined interval. The water level may be, for example, the distance downward from the upper limit of the irrigation channel 620.

[0064] The information providing server 100 acquires information (environmental data) obtained by the measuring device 200e, analyzes the environmental condition in the irrigation canal area 600 (for example, the water volume condition using the water level and flow velocity), and generates an image showing the spatial distribution of the environmental condition (for example, the water level distribution, flow velocity distribution, and water volume distribution) and provides it to the user.

[0065] According to the third embodiment, by using the environmental data measured by the measuring device 200e, it is possible to instantly grasp the location of a leak in the irrigation channel 620, the location of a flooded road 630, and the location of a lack of water. Therefore, for example, during heavy rain, the user can grasp the flooding condition of the river 610 and the irrigation channel 630 over time without having to go to the irrigation channel 620 to check, and can determine a more appropriate evacuation route based on the flooding condition of the road 630, etc. Furthermore, according to the third embodiment, when water is taken from a river, it is possible to adjust the operation status of the pump according to the water level of the irrigation channel 620. Therefore, it is possible to save on electricity costs, labor costs, etc.

[0066] (Fourth Example) FIG. 11 is a diagram illustrating an example of installation of the measuring device 200 in the fourth embodiment. In the fourth embodiment, one or more measuring devices 200f are installed at predetermined intervals within a paddy field area 700, and a measuring device 200g is also installed near the water inlet and outlet. The measuring device 200f is provided with, for example, a water level sensor and a water temperature sensor, and measures the water level and water temperature at the installation point at a predetermined interval. The measuring device 200g is also provided with, for example, a water level sensor and a flow rate sensor, and measures the water level and flow rate at the installation point at a predetermined interval.

[0067] The information providing server 100 acquires information (environmental data) obtained by the measuring devices 200f, 200g, analyzes the environmental conditions in the paddy field area 700, and generates an image showing the spatial distribution of the environmental conditions to provide to the user. For example, in the fourth embodiment, the water level distribution and water temperature distribution in the paddy field area 700 can be provided to the user.

[0068] According to the fourth embodiment, the environmental data measured by the measuring devices 200f and 200g can be used to achieve appropriate management of the paddy field area 700. Therefore, for example, because excessively high water temperature can cause poor growth and sterility, the temperature can be lowered by gradually introducing water into the paddy field area 700 through the water inlet. In this case, the amount of water introduced into the paddy field area 700 can be controlled based on the water level and amount measured by the measuring device 200g installed near the water inlet. Furthermore, according to the fourth embodiment, it is possible to detect an excessive drop in the water level due to a leak in the paddy field area 700, and to identify and predict where and how the water level will change when a particular location in the paddy field area 700 is damaged.

[0069] Each of the first to fourth embodiments described above may be combined with part or all of the other embodiments. As described above, the type of sensor to be mounted on the measuring device 200 can be selected depending on the environment to be measured, so that necessary information can be appropriately acquired and more accurate analysis and prediction of the environment can be performed.

[0070] According to the above-described embodiment, the measuring device 200 includes a connecting part 202a that can be detachably connected to a support part 206 that extends from underground to above, a first sensor 240 that measures conditions on the ground, a communication part 220 that transmits environmental data measured by the first sensor 240 and a second sensor 250 that measures conditions underground to the outside, a battery 210 (an example of a power supply part) that supplies power to the first sensor 240, the second sensor 250, and the communication part 220, and a container body 202 (an example of a storage part) that stores equipment inside, including a control part 230 that controls at least the communication part 220, and a lid part 204 that opens and closes an opening that allows equipment to be taken in and out of the container body 202, thereby making it possible to acquire environmental data at a lower cost.

[0071] According to the embodiment, the measuring device 200 can be installed or replaced in a short time to suit various environments, thereby achieving further cost reduction. Furthermore, according to the embodiment, by changing the type of sensor, the measuring device 200 can be installed to suit various environments, so various environmental data related to soil, weather, water, etc. can be easily obtained in real time at multiple locations, and this information can be used to more appropriately analyze soil conditions and make near-future predictions. Furthermore, according to the embodiment, the equipment and cables are stored within the measuring device 200, so deterioration due to the influence of water droplets, etc. can be suppressed, and breakdowns due to wild animals, etc. can also be suppressed.

[0072] Furthermore, according to the embodiment, since the wiring for the sensors, batteries, etc. is contained within the measuring device 200, there is little risk of the wiring being physically broken due to being torn apart by wild animals or getting caught on surrounding trees or branches, and since there is no deterioration of the wiring coating due to ultraviolet rays, maintenance management is reduced even when the device is installed outdoors.

[0073] Furthermore, according to the embodiment, sensors and wiring are concentrated in the vertical direction of the measuring device 200, making it possible to identify the storage and buried locations of the sensors and wiring. This allows for pinpointing and labor-saving work such as sensor replacement. Furthermore, when the measuring device 200 is installed in farmland, agricultural machinery working near the measuring device 200 will not accidentally catch and cut the sensors or wiring.

[0074] Furthermore, according to the embodiment, a large amount of environmental data can be collected inexpensively and viewed anytime, anywhere, making it possible to widely utilize the technology not only for large-scale farming but also for greenhouse cultivation and home gardening. By utilizing the measurement device 200 of the embodiment, it becomes possible to monitor the entire area under management (field, facility) thoroughly. For example, organic farming is known to require a great deal of time and effort to manage. However, by installing the measurement device 200 of the embodiment, it becomes possible to pinpoint abnormalities and address them at an early stage, which is expected to be particularly effective in organic farming. The technology according to the embodiment can be widely utilized in fields such as agriculture and forestry, for example, for environmental monitoring of a specific area, field management, facility management, crop cultivation, and consideration of effective land use.
