Description

[Technical Field]

[0001] The present invention relates to a farm management system. More specifically, the present invention relates to a farm management system capable of efficiently acquiring information related to the growth of crops cultivated on a farm. [Background Art]

[0002] In Japan, the problems of insufficient human resources for agriculture and aging of the farming population have become apparent, so improvements in crop productivity on farms are demanded more than ever before. As a method for stabilizing crop quality and yield, there is a demand for a system that grasps the growth status of crops and the damage status caused by pests and diseases, and performs cultivation management corresponding to variations.

[0003] In order to grasp the growth status of crops and the damage status caused by pests and diseases, it is effective to analyze images obtained by imaging cultivated crops, or analyze various parameters related to growth (temperature, humidity, carbon dioxide concentration, etc.). For example, Patent Document 1 discloses an agricultural vehicle equipped with a video camera that continuously photographs local areas in a farm while traveling on the farm, and a GPS. The locally captured image data is combined into a single composite image, which is used for grasping the growth status of crops across the entire farm.

[0004] Further, Patent Document 2 discloses a system in which a drone equipped with various sensors and cameras is caused to fly, real-time measurement values of various parameters related to crop growth such as solar radiation, temperature, humidity, and carbon dioxide concentration around a farm are acquired, and growth analysis of crops is performed based on the acquired measurement values. [Prior Art Literature] [Patent Literature]

[0005] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2001-120042 [Patent Document 2] Japanese Unexamined Patent Application Publication No. 2020-130088 [Summary of the Invention] [Problems that the invention aims to solve]

[0006] However, the technology disclosed in Patent Document 1 requires an operator to drive an agricultural vehicle around the farm while taking images, which necessitates manual labor. Furthermore, the vehicle's speed is not always constant, which can lead to blurry image data due to inconsistent focus. Additionally, it is not possible to image narrow areas where the agricultural vehicle cannot travel, such as between rows of parallel-arranged crops, thus preventing comprehensive imaging of the entire crop on the farm.

[0007] Furthermore, as mentioned in Patent Document 2 above, drones are susceptible to weather conditions and therefore their use is limited to indoors, such as inside agricultural greenhouses. Also, if the flight altitude is too high, it is not possible to accurately acquire parameters near crops, while if the flight altitude is too low, the airflow around the aircraft may affect the crops, or there is a risk of the propellers contacting the crops. In addition, due to battery limitations, long-term operation is difficult, making them unsuitable for use on large farms, among other problems with the operation of drones.

[0008] This invention was conceived in view of the above points, and aims to provide a farm management system that can efficiently acquire information on the growth of crops cultivated on a farm. [Means for solving the problem]

[0009] To achieve the above objectives, the farm management system of the present invention comprises a moving path formed in a meandering manner by straight paths extending along the rows of a plurality of crop rows at a predetermined height from the ground, and turning paths that alternately connect adjacent straight paths in the headland area of ​​the crop rows; a main body having wheels that can roll along the moving path and a drive source that drives the wheels; and a measuring device suspended vertically downward from the main body having a measuring unit capable of acquiring at least one of the following data: environmental data indicating the cultivation environment of the crops or growth data indicating the growth state of the crops.

[0010] Here, by providing a meandering movement path formed by a straight path extending along the rows of multiple crop rows at a predetermined height above the ground, and a winding path that alternately connects adjacent straight paths in the headland area of ​​the crop rows, the measuring device can be made to self-propel along this movement path over the entire area of ​​crop rows planted in the farm. Furthermore, since the movement path is provided at a predetermined height above the ground, it can move at a position approximately the same as the height of the crops, and the crops cultivation This will enable accurate measurement of various data related to the environment and growth conditions.

[0011] Furthermore, the measuring device has a main body with wheels that can roll along a movement path and a drive source that drives the wheels, allowing it to travel safely and stably along the movement path while the wheels are driven by the driving force from the drive source. In addition, by using a motor as the drive source and keeping the motor at a steady rotation, the measuring device can be kept in steady motion, making it possible to acquire uniform and accurate data on crops in the farm.

[0012] Furthermore, the measuring device has a measuring unit suspended vertically downward from the main body that can acquire at least one data set, either environmental data indicating the cultivation environment of the crop or growth data indicating the growth state of the crop. This makes it possible to acquire environmental data and growth data of the crop while the measuring device moves along a travel path.

[0013] Furthermore, if the movement path is constructed using wire ropes stretched within the farm, the simple structure of the movement path makes installation easy, even in confined spaces. In addition, the path and height can be flexibly changed after installation, making it possible to change the path and height according to the growth stage of the crops, for example.

[0014] Furthermore, if the wheels of the measuring device have grooves along their outer surface into which wire ropes can be engaged, the wire ropes will fit into the grooves of the wheels, preventing the wheels from derailing and allowing for stable movement.

[0015] Furthermore, if the main body and measuring section of the measuring device are located on one side of a vertical plane including the wire rope with respect to the plane on which the movement path is installed, and the rotation path consists of a first rotation path in which the measuring device rotates around the outer circumference of the wire rope and a second rotation path in which the measuring device rotates around the inner circumference of the wire rope, then the measuring device can rotate smoothly without deviating from the movement path, regardless of whether it rotates around the outer or inner circumference of the wire rope.

[0016] Furthermore, if the first turning path has a pair of flange sections with an arc-shaped outer circumference at each corner of the headland area, one end of a first wire rope stretched to form a straight path is connected to the flange sections, and the pair of flange sections are connected to each other by a second wire rope, and the first rail section connects the first wire rope and the second wire rope in an arc along the outer circumference of the flange sections, then the measuring device can smoothly turn around on the outer circumference side of the wire rope.

[0017] Furthermore, if the second turning path has a second rail section at each corner of the headland area that arc-shaped connects the intersection of the first wire rope and the third wire rope, which is stretched perpendicular to the first wire rope and across the crop rows, the measuring device can smoothly turn around the inner circumference of the wire rope.

[0018] Furthermore, if the measuring device has a reading unit that reads position information provided at a predetermined location on the travel path, and a position correction unit that corrects the current position based on the position information read by the reading unit, then the current position of the measuring device while it is traveling along the travel path can be accurately determined, making it possible to accurately link the measurement data measured by the measuring unit with the measurement position.

[0019] Furthermore, if the measurement unit has a sensor that measures at least one of the environmental data—temperature, humidity, carbon dioxide concentration, and solar radiation—it becomes possible to acquire spatial and time-series data related to the crop's growing environment.

[0020] Further, in a case where the measurement unit includes an imaging device that acquires moving images of crops as growth data, it becomes possible to acquire spatial data and time-series data of moving images representing the growth status of the crops.

[0021] Further, in a case where the imaging device includes a first imaging device that images a crop row on one side across an inter-row space, and a second imaging device that images a crop row on the other side across the inter-row space, it becomes possible to simultaneously acquire moving images of the crops on both sides when moving along a linear path through the inter-row space. Effects of the Invention

[0022] The farm management system according to the present invention can efficiently acquire information related to the growth of crops cultivated on a farm. Brief Description of the Drawings

[0023] [Figure 1] It is a schematic diagram of the farm management system according to an embodiment of the present invention. [Figure 2] It is a diagram showing the measurement device according to an embodiment of the present invention. [Figure 3] It is a diagram showing a movement route according to an embodiment of the present invention. [Figure 4] It is a diagram showing the detailed structure of a flange portion provided on a turning route in the movement route according to an embodiment of the present invention. Mode for Carrying Out the Invention

[0024] Hereinafter, a farm management system according to an embodiment of the present invention will be described with reference to the drawings to facilitate understanding of the present invention. For convenience of description in each drawing, the direction upward from the ground of a farm is defined as upward, the direction opposite to upward is defined as downward, the axial direction represented by upward and downward is defined as the vertical direction, and the direction perpendicular to the vertical direction is defined as the horizontal direction.

[0025] Figure 1 is a schematic diagram of a farm management system 1 according to an embodiment of the present invention. As shown in Figure 1, the farm management system 1 consists of a movement path T arranged along the rows of multiple crop rows C to be cultivated, and a measuring device 2 that moves along this movement path T to acquire environmental data and growth data of crops. The measuring device 2 is connected to a terminal 4 used by a user via a network line 3 such as the Internet or LAN, enabling bidirectional communication. The user can input instructions to the measuring device 2 through the terminal 4, or receive measurement data measured by the measuring device 2 on the terminal 4.

[0026] Figure 2 shows the detailed structure of the measuring device 2 according to this embodiment. The measuring device 2 is self-propelled and mainly consists of a main body 21 and a measuring unit 22.

[0027] The main body 21 has a motor 212 above a rectangular first support column 211, a battery 213 that supplies power to the motor 212, wheels 214 that rotate synchronously with the motor 212, a reading unit 215 that reads position markers 5 installed on the movement path T, and a control box 216 that houses control devices including a CPU 216a, memory 216b, and a hard disk drive (HDD) 216c.

[0028] The wheel 214 has a groove 214a of a predetermined depth formed along its outer circumference, and the wire rope W that constitutes the movement path T can engage with this groove 214a. By driving the motor 212, the wheel 214 can roll stably on the wire rope W. An encoder (not shown) is provided on the axle portion of the wheel 214, and the output signal from the encoder is transmitted to the CPU 216a, which counts the rotations of the wheel 214, calculates the distance traveled from the starting point, and temporarily stores it in memory 216b.

[0029] Furthermore, the structure of the wheel 214 may include a first wheel and a second wheel on the left and right sides, with these two wheels connected by a shaft connected to the motor 212, and the wire rope W may be sandwiched between the first wheel and the second wheel.

[0030] Furthermore, the wheel 214 does not necessarily have to be a single wheel. For example, if the wheel 214 consists of multiple wheels, the oscillation when rolling on the wire rope W is suppressed, allowing for more stable movement. Therefore, the number of wheels 214 may be increased depending on the weight or size of the main body 21 or the measuring unit 22.

[0031] A reading unit 215 with a roughly U-shaped cross-section is installed at the upper end of the first support column 211. As will be described later, the reading unit 215 is capable of reading position markers 5 provided at any position along the movement path T, and has a light-emitting unit 215a on one side and a light-receiving unit 215b on the opposite side.

[0032] When the reading unit 215 passes a position marker 5 located at any position on the movement path T, it transmits the precise current position of the measuring device 2 to the CPU 216a according to the degree of light blockage from the light-emitting unit 215a. Then, calculations are performed based on the encoder, and the current position is compared with the current position temporarily stored in the memory 216b, and the current position is corrected as necessary.

[0033] Here, the method for recognizing the current position of the measuring device 2 is not necessarily limited to the configuration described above. For example, instead of an encoder, an acceleration sensor or the like may be used to calculate the distance traveled. Alternatively, a GPS receiver may be installed on the measuring device 2 to receive radio waves from satellites and recognize its absolute position. However, if the farm is located inside a greenhouse, it may not be possible to receive radio waves from satellites. Therefore, it is preferable to use a method that calculates the amount of movement using sensors, including an encoder, and estimates the current position, as described above.

[0034] The measuring unit 22 has a cylindrical second support body 221 to which a temperature and humidity sensor 222 and an imaging device 223 are fixed. Multiple through holes (not indicated by reference numerals) are formed above the second support body 221 into which the projections 217 of the first support body 211 can be inserted. The second support body 221 is firmly fixed to the first support body 211 by fixing it with a fixing means such as a nut while the projections 217 of the first support body 211 are inserted into the through holes of the second support body 221.

[0035] As shown in Figure 3, the main body 21 and measuring section 22 of the measuring device 2 are located on one side of the vertical plane including the wire rope W with respect to the plane on which the wire rope W is installed, which makes it easy for the weight balance to become unstable during operation. Therefore, the projection 217 of the first support column 211 is set to be slightly longer than the width of the second support column 221, making it possible to change the horizontal mounting position of the second support column 221 relative to the first support column 211. In addition, as mentioned above, multiple through holes are formed in the second support column 221.

[0036] With the above configuration, the horizontal and vertical mounting positions of the second support column 221 relative to the first support column 211 can be arbitrarily adjusted. For example, the second support column 221 can be mounted to the first support column 211 at the optimal position depending on the number and weight of sensors mounted on the second support column 221, thereby suppressing the oscillation of the measuring device 2 while it is traveling along the movement path T.

[0037] The temperature and humidity sensors 222 are installed at three predetermined intervals from the top to the bottom of the second support column 221. The three temperature and humidity sensors 222 are identical and can simultaneously measure ambient temperature and humidity at each height of the planted crops. The measured temperature and humidity are then stored in the HDD 216c, linked to the location and time along the movement path T.

[0038] The temperature and humidity sensor 222 is housed in a hard case 222a. An outside air intake (not shown) is formed on the bottom of the hard case 222a, and an exhaust fan 222b is installed on the side. During measurement, the exhaust fan 222b is driven continuously or at predetermined intervals to draw outside air into the hard case 222a. This prevents the temperature inside the hard case 222a from deviating from the ambient temperature around farm F, thereby improving the measurement accuracy of the temperature and humidity sensor 222.

[0039] In addition to temperature and humidity, environmental data such as carbon dioxide concentration and solar radiation may also be measured using CO2 sensors and solar radiation sensors, for example, to measure carbon dioxide concentration and solar radiation, which are essential for photosynthesis in crops.

[0040] Furthermore, the number of temperature and humidity sensors 222 installed is not necessarily limited to three, and the number of sensors installed may be changed as appropriate depending on the type and height of the crop being measured.

[0041] The imaging device 223 is for capturing moving images of crops and is installed at an arbitrary height on the second support column 221. The imaging device 223 is a 3D camera that can acquire 3D images including depth information in addition to 2D images, and can output the three-dimensional shape and spatial positional relationship of the subject crop as data. By capturing the growth stage of crops in three dimensions with the imaging device 223, such as the area of ​​leaves and flowers, the thickness of stems, or the volume of fruits, the growth status of crops can be grasped more accurately, making it possible to detect the timing of harvest and abnormalities in crops early. In this embodiment, the imaging device 223 consists of two devices: a first imaging device 223a that images one row of crops between rows, and a second imaging device 223b that images the other row of crops, both of which are installed facing opposite directions.

[0042] Here, the imaging device 223 does not necessarily have to consist of a first imaging device 223a and a second imaging device 223b. However, as in this embodiment, by installing two imaging devices facing in both directions, one on one side and the other on the other, it becomes possible to simultaneously image the crop rows C on both sides when the measuring device 2 moves along the movement path T between the rows of crop rows C. Therefore, it is possible to efficiently acquire dynamic image data without having to move back and forth to image each crop row C.

[0043] Furthermore, the imaging device 223 does not necessarily have to be a 3D camera; it may be a 2D camera. When a 2D camera is used, stereo imaging or photogrammetry can be used to capture the crops in three dimensions, similar to when imaging with a 3D camera, making it possible to detect the timing of crop harvesting and any abnormalities in the crops at an early stage.

[0044] Next, the travel path T on which the measuring device 2 travels will be explained using Figure 3. Figure 3 is an enlarged view of a part of the travel path T according to this embodiment. The travel path T consists of a straight path TS that extends along the crop row C and a winding path TR that alternately connects the straight paths TS in the headland area H of the crop row C. By repeating these straight paths TS and winding paths TR, a meandering path is formed, allowing the measuring device 2 to travel to every corner of the farm F. Note that the travel path T only needs to include a winding path, and may be, for example, a circular path that includes a winding path.

[0045] The movement path T is installed in the air so as to be positioned above the crops cultivated on farm F. When the measuring device 2 is suspended from the movement path T, the temperature and humidity sensor 222 and imaging device 223 mounted on the measuring device 2 are adjusted to be at the height of the crop to be measured. For example, if bell pepper seedlings are planted as crops, the bell pepper seedlings will grow to a maximum height of about 1 to 1.5 m, so the movement path T is installed at a height of about 2 m from the ground, and when the measuring device 2 is suspended from that position, the temperature and humidity sensor 222 and imaging device 223 will be positioned at any point between the base of the bell pepper seedling and the growing point.

[0046] Next, the specific configuration of the movement path T will be explained. As described above, the movement path T consists of a straight path TS and a rotating path TR. The rotating path TR consists of a first rotating path TR1 in which the measuring device 2 rotates on the outside of the wire rope W, and a second rotating path TR2 in which the measuring device 2 rotates on the inside of the wire rope W.

[0047] First, let's describe the movement path, including the first turning path TR1. Inside the greenhouse, there are multiple horizontal members 6 that support the load of the roof, etc. (If horizontal members 6 are not installed, equivalent members are installed separately). The first wire rope W1, which constitutes the straight path TS, has one end connected to the horizontal members 6 installed at both ends in the longitudinal direction of the greenhouse via mounting fittings 7 such as turnbuckles, and is stretched along the crop rows C.

[0048] At each corner of the first turning path TR1, a pair of flange sections 8a and 8b are positioned on either side of a crop row C. These flange sections 8a and 8b are suspended from horizontal members 6 inside the greenhouse via brackets 61. As shown in Figure 4, the flange sections 8a and 8b are plate-like bodies formed in an arc shape along their outer circumference. Locking holes 81 and 82 are formed in the flange sections 8a and 8b, respectively, and the other end of the first wire rope W1 that constitutes the straight path TS is inserted into and locked into the locking holes 81 and 81 of the flange sections 8a and 8b.

[0049] Furthermore, the pair of flange portions 8a and 8b are connected by a second wire rope W2 stretched in a lateral direction perpendicular to the linear direction, with one end and the other end of the second wire rope W2 being locked into the locking holes 82 of flange portion 8a and flange portion 8b, respectively.

[0050] Furthermore, a first rail section 9a is installed along the outer circumference of flange section 8a to connect the first wire rope W1 and the second wire rope W2, and similarly, a first rail section 9b is installed along the outer circumference of flange section 8b to connect the first wire rope W1 and the second wire rope W2.

[0051] With the above configuration, when the measuring device 2, which is moving straight along the first wire rope W1, approaches the first turning path TR1, it is guided by one of the first rail sections 9a and turns around the flange section 8a to pass through the second wire rope W2, and then, guided by the other first rail section 9b, it turns around the flange section 8b to move to the adjacent first wire rope W1.

[0052] Next, the movement path including the second turning path TR2 will be explained based on Figure 3. The second turning path TR2 is connected to the intersection O where the first wire rope W1, which runs in a straight direction, and the third wire rope W3, which is stretched perpendicular to the straight direction and crosses the crop row C, intersect, by a pair of second rail sections 10a and 10b that are arranged side by side on either side of the crop row C. The third wire rope W3, which is stretched in a direction that crosses the crop row C, is secured to horizontal members and supports (not shown).

[0053] The second rail sections 10a and 10b are hollow tube-shaped and connect the first wire rope W1 and the third wire rope W3 at the intersection O, arranged to form a gentle arc in plan view. As a result, when the measuring device 2, which is moving straight along the first wire rope W1, approaches the second turning path TR2, it turns while being guided by the second rail section 10a to move the third wire rope W3, and then turns while being guided by the other second rail section 10b to move to the adjacent first wire rope W1.

[0054] As described above, the turning path of the movement path T according to this embodiment is composed of a first turning path TR1 and a second turning path TR2, so that even a measuring device 2 equipped with a main body 21 and a measuring unit 22 on one side of the vertical surface including the wire rope W can move smoothly along the movement path T.

[0055] In this embodiment, the measuring device 2 has a configuration in which the main body 21 and measuring unit 22 are arranged on one side of the vertical plane including the wire rope W. However, even if the measuring device has the main body 21 and measuring unit 22 arranged on the opposite side of the vertical plane including the wire rope W, a first turning path TR1 can be arranged when turning around the outside of the wire rope W, and a second turning path TR2 can be arranged when turning around the inside.

[0056] Along the movement path T, more specifically, after turning off the first turning path TR1 (or the second turning path TR2), a position marker 5 is installed near the start of the adjacent straight path TS. This position marker 5 is arbitrary encoded information, such as a one-dimensional barcode, that can be read by the aforementioned reading unit 215, and stores the position information of the position marker 5 (for example, the row number of crop row C, or the start and end positions on the straight path TS).

[0057] Then, when the measuring device 2, which is self-propelled along the movement path T, passes this position marker 5, the reading unit 215 reads the encoded information, and based on the distance information measured by the encoder, it compares it with the position information of the measuring device 2 stored in the memory 216b, and corrects the current position as necessary.

[0058] As described above, the measuring device 2 can acquire crop growth data and environmental data by traveling along the movement path T to every corner of the farm F. Furthermore, since the movement path T is installed at a predetermined height above the ground, there is no need to lay rails or anything similar on the ground of the farm F, so it does not hinder the movement of workers within the farm F, and installation and removal work within the farm F can be carried out efficiently.

[0059] In the above embodiment, we assumed a greenhouse where crops were planted as farm F, but this can also be applied to open-field cultivation fields and orchards. In this case, instead of the horizontal members 6 that support the roof of the greenhouse to support the wire rope W, posts or the like can be installed at both ends in the longitudinal direction of the crop row, and the wire rope W can be secured between the posts.

[0060] Furthermore, the measuring device 2, which patrols within farm F, not only has the function of acquiring data such as growth data and environmental data, but can also be equipped with a pesticide spraying device to spray pesticides on crops while autonomously moving along the travel route T, or it can be equipped with an automatic harvesting mechanism to harvest target crops while autonomously moving along the travel route.

[0061] Furthermore, in the above-described embodiment, a field where crops are cultivated was assumed as farm F, but the present invention can also be applied to, for example, a livestock barn where livestock are raised. When the present invention is applied to a livestock barn, a movement path T is formed along the livestock shed, and by moving the measuring device 2 along this movement path T, data such as temperature and humidity, which are closely related to the growth of livestock, can be acquired.

[0062] As described above, the farm management system according to the present invention can efficiently acquire information regarding the growth of crops cultivated on a farm. [Explanation of Symbols]
