Patent Document 1 discloses a root vegetable digger that harvests root vegetables such as Chinese yams by digging up the soil and root vegetables upward.

Patent No. 6716155

The root vegetable digger of Patent Document 1 creates a deep trench to harvest root vegetables. Even if the ground is leveled after harvesting, this trench remains an area that is softer than the surrounding soil. This can cause the wheels of the working equipment to get stuck in the trench, which can lead to breakdowns of the working equipment used later. In addition, once the ground is leveled, it can be difficult for the worker to grasp the trench while working.

(Embodiment 1)
A danger area management system 1000 according to the present embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in FIG. 1, the danger area management system 1000 includes one or more terminals 100 and a danger area management device 200. The terminals 100 are mounted on the work devices 30 when work is performed in the field 500. For example, the first terminal 100-1 is mounted on the first work device 30-1, and the second terminal 100-2 is mounted on the second work device 30-2. The terminals 100 may be removed when work is not performed in the field 500. For example, the first terminal 100-1 mounted on the first work device 30-1 when work is performed in the field 500 may be mounted on the second work device 30-2 when work is performed in the field 500.

The first work device 30-1 performs work in the field 500 and changes the ground surface of the field 500. For example, as shown in FIG. 2, the first work device 30-1 forms a danger area 650, such as a deep ditch, by performing work in the field 500. The danger area 650 represents an area that may cause a breakdown of the second work device 30-2, such as a tractor, that performs work thereafter. For example, when the second work device 30-2 travels through the danger area 650, the wheels of the second work device 30-2 may get stuck in the deep ditch, causing a breakdown of the second work device 30-2. The second work device 30-2 may be the same as or different from the first work device 30-1. The second work device 30-2 performs work by traveling on the ground, for example.

The danger area management system 1000 detects the danger area 650 based on the operation information of the first work device 30-1. For example, the first terminal 100-1 mounted on the first work device 30-1 measures the position of the first work device 30-1 working in the field 500 as the positioning position 610. The positioning position 610 is measured along the trajectory 600 along which the first work device 30-1 has moved. Therefore, the trajectory 600 is detected by connecting the positioning positions 610 in the order of the measured times. Here, the relative position of the danger area 650, for example, the area where a deep trench is formed by the first work device 30-1 with respect to the positioning position 610 is determined according to the work machine performing the work on the first work device 30-1. Therefore, the danger area management system 1000 detects the danger area 650 based on the positioning position 610.

The danger area management system 1000 notifies a user, for example, an operator of the second work device 30-2 that will perform the work later, of the position of the detected danger area 650. The operator may not be able to grasp the position of the danger area 650 due to work performed after the first work device 30-1, such as leveling. For this reason, the user can check the position of the danger area 650 notified by the danger area management system 1000 to prevent malfunctions caused by the second work device 30-2 traveling through the danger area 650. In addition, the danger area management system 1000 may determine the route of the second work device 30-2 so as to prevent the occurrence of malfunctions of the second work device 30-2 in the danger area 650 when the second work device 30-2 travels and performs work automatically.

The first work device 30-1 may include a work machine that forms a trench, such as a tractor that pulls a trencher. The first work device 30-1 may also include a trencher that is formed integrally with the work machine and is self-propelled to form a deep trench in the field 500. The first work device 30-1 may also include a tractor that pulls a plow.

(Configuration of Danger Area Management System)
As shown in Fig. 1, the configuration of a terminal 100 included in a hazardous area management system 1000 will be described. As shown in Fig. 3, the terminal 100 includes an input/output device 110, a positioning device 115, a computing device 120, a communication device 130, and a storage device 140. The terminal 100 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the computing device 120 to execute processing is input to the input/output device 110. In addition, the input/output device 110 outputs the results of the processing executed by the computing device 120. The input/output device 110 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

The positioning device 115 measures the position of the work device 30 on which the positioning device 115 is mounted by measuring the position of the device itself at each time. For example, the positioning device 115 measures the position of the work device 30 at a predetermined time interval, for example, at 10 second intervals. The positioning device 115 is, for example, a GNSS (Global Navigation Satellite System) receiver.

The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 130 transfers signals acquired from the danger area management device 200 to the calculation device 120. The communication device 130 also transfers signals generated by the calculation device 120 to the danger area management device 200. The communication device 130 includes various interfaces such as a transceiver used for wireless communication such as a wireless LAN (Local Area Network) or a cellular network, a NIC (Network Interface Card), and a USB (Universal Serial Bus).

The communication device 130 may also receive status information from the working device 30 that indicates the state of the working device 30. The status information indicates, for example, the speed, steering angle, engine RPM, and ON/OFF status of various clutches of the working device 30. Furthermore, when the working device 30 is a vehicle that tows a working machine, the status information may include information such as the PTO (power take-off) RPM when transmitting power to the working machine and the hitch angle that indicates the attitude of the working machine. For example, when the working machine is a trencher or plow, the hitch angle indicates the depth of the ground to be excavated by the working machine.

The storage device 140 outputs operation information, including status information and position information, to the danger area management device 200, and stores various data for displaying the detected danger area 650, such as the display program 400. The storage device 140 is used as a non-transitory tangible storage medium for storing the display program 400. The display program 400 may be provided as a computer program product recorded on a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

The computing device 120 reads and executes the display program 400 from the storage device 140, and performs various data processing to display the danger area 650. For example, the computing device 120 includes a central processing unit (CPU) and the like.

The computing device 120 reads and executes the display program 400 to realize an operation information acquisition unit 150, a path generation unit 160, a steering unit 170, and a display unit 180, as shown in FIG. 4. The operation information acquisition unit 150 acquires position information from the positioning device 115 and status information from the work device 30. The operation information acquisition unit 150 outputs the acquired position information and status information to the danger area management device 200 as operation information. The path generation unit 160 generates a movement path for the work device 30 to perform work according to information input by the user. The steering unit 170 generates a signal for steering the work device 30 based on the generated movement path. Therefore, the work device 30 moves within the field 500 based on the instruction of the steering unit 170. The display unit 180 displays area information indicating the position of the danger area 650 in the field 500.

Next, the configuration of the danger area management device 200 shown in FIG. 1 will be described. As shown in FIG. 5, the danger area management device 200 includes an input/output device 210, a calculation device 220, a communication device 230, and a storage device 240. The danger area management device 200 is, for example, a computer. Information for the calculation device 220 to execute processing is input to the input/output device 210. The input/output device 210 also outputs the results of the processing executed by the calculation device 220. The input/output device 210 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel. The input/output device 210 may be omitted.

The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 230 transfers information acquired from the terminal 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the terminal 100. The communication device 230 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

The storage device 240 stores various data for detecting a danger area 650 caused by the work of the working device 30, such as the farm field data 410, and the danger area management program 420. The storage device 240 is used as a non-transitory tangible storage medium for storing the danger area management program 420. The danger area management program 420 may be provided as a computer program product recorded on a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server.

The field data 410 stores information about the field 500. For example, the field data 410 stores information representing the area of the field 500 and the location of the danger area 650.

The computing device 220 reads out the danger area management program 420 from the storage device 240 and executes it to perform various data processing to detect the danger area 650. For example, the computing device 220 includes a central processing unit (CPU) and the like.

The computing device 220 reads and executes the danger area management program 420, thereby implementing a data storage unit 250, an area detection unit 260, and an output unit 270, as shown in FIG. 4. The data storage unit 250 stores the farm field data 410. The area detection unit 260 detects a danger area 650 based on the operation information of the work device 30. The output unit 270 outputs area information indicating the position of the danger area 650 to the terminal 100.

(Operation of the Danger Area Management System)
A method for the danger area management system 1000 to detect a danger area 650 in a field 500 will be described. When an operator starts work in the field 500 using an operating device 30, for example, a first operating device 30-1, the operator performs an operation to input work field information representing the field 500 in which work is to be performed, for example, the name and location of the field 500, to the input/output device 110 of the first terminal 100-1. The arithmetic unit 120 of the first terminal 100-1 reads and executes a display program 400 in response to an operation by the operator. When the display program 400 is read and executed, the arithmetic unit 120 starts the process shown in FIG. 6, which is part of a danger area management method.

In step S110, the operation information acquisition unit 150 realized by the calculation device 120 acquires operation information of the first work device 30-1 at each time. For example, the operation information acquisition unit 150 acquires position information representing the position measured by the positioning device 115. The operation information acquisition unit 150 also acquires status information representing the status of the first work device 30-1 from the first work device 30-1. The operation information acquisition unit 150 outputs the acquired position information and status information as operation information to the danger area management device 200. For example, when work in the field 500 is completed, the worker inputs end information representing the end of the work to the input/output device 110. When the end information is input, the operation information acquisition unit 150 outputs the acquired operation information to the danger area management device 200. The operation information acquisition unit 150 may sequentially output the acquired operation information to the danger area management device 200. The information output by the operation information acquisition unit 150 may include work field information that represents the field 500 in which work is performed by the first work device 30-1.

In step S120, the area detection unit 260 of the danger area management device 200 extracts operation information when the first work device 30-1 is working. For example, the area detection unit 260 extracts operation information corresponding to status information indicating that the work machine is working. For example, the area detection unit 260 determines that the work machine is working when the status information indicates that the work machine is lowered. For example, the area detection unit 260 determines that the work machine is lowered based on the hitch angle included in the status information.

In step S130, the area detection unit 260 detects a danger area 650 in the field 500 based on the operation information when the first work device 30-1 is working. For example, the area detection unit 260 extracts the positioning position 610 of the first work device 30-1 represented by the operation information when the first work device 30-1 is working. As shown in FIG. 7, the area detection unit 260 detects a work area corresponding to the extracted positioning position 610, for example, a left work area 660 and a right work area 670. The work area represents the area where the first work device 30-1 is working when it is present at the positioning position 610. For example, the relative position of the work area with respect to the positioning position 610 is determined in advance according to the work machine incorporated in the first work device 30-1 or the work machine towed by the first work device 30-1.

In the example shown in FIG. 7, when the first work device 30-1 is at the first positioning position 610-1, work is performed in the first left working area 660-1 and the first right working area 670-1. When the first work device 30-1 is at the second positioning position 610-2, work is performed in the second left working area 660-2 and the second right working area 670-2. When the first work device 30-1 is at the third positioning position 610-3, work is performed in the third left working area 660-3 and the third right working area 670-3.

The area detection unit 260 detects an area connecting the detected work areas in the order of the time when the corresponding positioning positions 610 were measured as the danger area 650. For example, the area detection unit 260 detects an area connecting the left work areas 660 in the order of the time when the corresponding positioning positions 610 were measured as the first danger area 650-1. The area detection unit 260 also detects an area connecting the right work areas 670 in the order of the time when the corresponding positioning positions 610 were measured as the second danger area 650-2.

The area detection unit 260 associates the position of the detected danger area 650 with the corresponding field 500 and stores it in the field data 410. For example, the area detection unit 260 determines the corresponding field 500 based on the work field information included in the operation information. The work field information represents, for example, information about the field 500 input by the user.

In this way, the danger area management device 200 detects the danger area 650 caused by the work of the work device 30 based on the operation information of the work device 30.

Next, a method in which the danger area management system 1000 notifies the user of the position of the danger area 650 will be described. For example, a method in which the danger area management system 1000 controls the second work device 30-2 so as to suppress the occurrence of a breakdown of the second work device 30-2 within the danger area 650 when the second work device 30-2 automatically moves and works within the farm field 500 will be described.

For example, a user inputs an operation for performing work in the field 500 with the second work device 30-2 to the input/output device 110 of the second terminal 100-2 mounted on the second work device 30-2. For example, the user inputs an operation for setting a work path 700 in order to perform plowing using the second work device 30-2 in the field 500 after a crop, for example a root vegetable such as burdock or yam, has been harvested by the first work device 30-1. When the user's operation is input, the calculation device 120 of the second terminal 100-2 reads and executes the display program 400. When the display program 400 is read and executed, the calculation device 120 starts the process shown in FIG. 8, which is part of the danger area management method.

In step S210, the path generation unit 160 implemented by the calculation device 120 requests area information representing the position of the danger area 650 from the danger area management device 200. For example, the user inputs field information representing the field 500 in which work is to be performed to the input/output device 110. The path generation unit 160 outputs the input field information to the danger area management device 200.

In step S220, the output unit 270 of the danger area management device 200 outputs area information to the second terminal 100-2 in response to a request from the second terminal 100-2. For example, the danger area management device 200 extracts area information corresponding to the field 500 in which the second work device 30-2 will perform work from the field data 410 based on the field information acquired from the second terminal 100-2. The extracted area information is output to the second terminal 100-2.

In step S230, the path generating unit 160 of the second terminal 100-2 generates a work path for the second work device 30-2 based on the area information and the information input by the user. For example, the path generating unit 160 generates a work path in accordance with the information input by the user so that the occurrence of a breakdown of the second work device 30-2 in the danger area 650 is suppressed. For example, as shown in FIG. 9, the path generating unit 160 determines the work path 700 so that it intersects with the direction in which the danger area 650 extends. For example, the path generating unit 160 displays an image representing the danger area 650 in the farm field 500. The user checks the danger area 650, determines the direction in which the straight line portion of the work path 700 extends so that the occurrence of a breakdown of the second work device 30-2 in the danger area 650 is suppressed, and inputs the determined direction to the input/output device 110. For example, the direction in which the straight line portion of the work path 700 extends is determined to be different from the direction in which the danger area 650 extends. The path generation unit 160 determines the work path 700 based on the determined direction.

In step S240, the display unit 180 displays information representing the determined work path 700 and area information representing the position of the danger area 650. The user checks the position of the danger area 650 and the work path 700, and inputs an operation to start work into the input/output device 110 of the second terminal 100-2.

In step S250, when an operation to start work is input, the steering unit 170 steers the second work device 30-2 so that the second work device 30-2 moves along the work path 700. As a result, the second work device 30-2 moves so as to intersect with the danger area 650, preventing the wheels of the second work device 30-2 from getting stuck in the grooves of the danger area 650.

In this way, the danger zone management system 1000 suppresses the occurrence of failures of the second work device 30-2 in the danger zone 650 caused by the work of the first work device 30-1.

(Modification)
The configuration described in the embodiment is an example, and the configuration can be changed to the extent that the function is not impaired. For example, in step S120 shown in FIG. 6, the area detection unit 260 of the dangerous area management device 200 may extract operation information when performing work based on the position information of the first working device 30-1. For example, as shown in FIG. 2, the dangerous area management device 200 divides the trajectory 600 of the first working device 30-1 into a straight trajectory 601 that moves linearly and a turning trajectory 602 that turns based on the positioning position 610 of the first working device 30-1. For example, the area detection unit 260 determines the traveling direction of the first working device 30-1 at each of the positioning positions 610 based on two positioning positions 610 that are adjacent in measured time. When the period during which the difference between the determined traveling directions is equal to or less than a threshold continues for a predetermined period or more, the area detection unit 260 determines the corresponding positioning position 610 as the positioning position 610 included in the straight trajectory 601. The area detection section 260 extracts operation information indicating the measured position 610 included in the straight line trajectory 601 as operation information when the first work device 30-1 is performing work.

In addition, in step S130 shown in FIG. 6, the area detection unit 260 may detect a danger area 650 based on the trajectory 600 of the first work device 30-1 while working, for example, the straight-line trajectory 601, and the relative position of the work area with respect to the positioning position 610. For example, the area detection unit 260 detects the work area corresponding to each point on the straight-line trajectory 601 as the danger area 650. For example, the area detection unit 260 may detect an area that has moved on the straight-line trajectory 601 by the relative position of the work area with respect to the positioning position 610 as the danger area 650.

The second work device 30-2 may be moved manually by a user, for example, a worker, to perform work. In this case, the second terminal 100-2 displays a field image 800 representing the range of the danger area 650 in the field 500, as shown in FIG. 10. In the example shown in FIG. 10, the field image 800 includes a danger portion 810 representing the position of the danger area 650. The field image 800 may also include a device portion 820 representing the position of the second work device 30-2. The device portion 820 represents, for example, the shape of the second work device 30-2, for example the position of the wheels. The user checks the field image 800 to grasp the position of the danger area 650. The user checks the device portion 820 to grasp the position of the second work device 30-2, for example the position of the wheels of the second work device 30-2. Therefore, by checking the farm field image 800, the user operates the second work device 30-2 so as to prevent the occurrence of a breakdown of the second work device 30-2 due to the danger area 650. For example, the user operates the second work device 30-2 so that the wheels of the second work device 30-2 do not get stuck in the deep grooves of the danger area 650. This prevents the occurrence of a breakdown of the second work device 30-2 due to the danger area 650.

In the example shown in FIG. 10, the danger portion 810 may be displayed in different display forms, such as colors or patterns, depending on the level of danger, such as the depth of the groove. For example, a danger portion 810 with a groove depth greater than a threshold may be displayed in a dark red color, and a danger portion 810 with a groove depth equal to or less than the threshold may be displayed in a light red color. By checking the display form of the danger portion 810, the user can grasp the level of danger in the danger area 650. Furthermore, the danger portion 810 may be classified into three or more types depending on the level of danger.

The above-described embodiments and modifications are merely examples, and the configurations described in each embodiment and modification may be modified and/or combined as desired as long as the functions are not impaired. Furthermore, some of the functions described in the embodiments and modifications may be omitted as long as the required functions can be realized. For example, some or all of the processing of the danger area management device 200 may be executed by the terminal 100. Furthermore, some of the processing of the terminal 100 may be executed by the danger area management device 200. Furthermore, the terminal 100 may be incorporated into the work device 30.

The terminal 100 shown in FIG. 1 does not have to be mounted on the work device 30 when the work device 30 performs work in the field 500. For example, the terminal 100 may control the work device 30 using wireless communication. In this case, the positioning device 115 shown in FIG. 3 is mounted on the work device 30 and outputs position information representing the measured positioning position to the terminal 100. In addition, the positioning device 115 mounted on the work device 30 may output the position information directly to the danger area management device 200.

The terminal 100 may also be used by the user only to confirm the position of the danger area 650 without being mounted on the work device 30. In this case, for example, the work device 30 may be provided with an operation information acquisition unit 150, and may output operation information directly to the danger area management device 200.

In addition, the danger area management system 1000 may not include the terminal 100 and may output area information representing the danger area 650 to an external terminal that is not included in the danger area management system 1000.

The danger area management program 420 may also include a display program 400.

The second working device 30-2 may also have a caterpillar track.
