The present invention relates to an operation management device, an operation management program, and an operation management method.
Main operations implemented in the case of lawn maintenance include lawn mowing operation and edge cutting operation. The lawn mowing operation is an operation of cutting lawns short in the entire area where the lawns are growing. On the other hand, the edge cutting operation is an operation of cutting lawns short in the vicinity of the boundary of the area in which the lawns are growing. Examples of the device used in the lawn mowing operation include a lawn mower disclosed in Patent Literature 1. Also, examples of the device used in the edge cutting operation include an edge cutter disclosed in Patent Literature 2.
In general, the lawn mowing operation and the edge cutting operation are not implemented simultaneously at the same point because it is required that the lawn mower and the edge cutter do not interfere with each other. Therefore, at each point in the vicinity of the boundary of the area where the lawns are growing, after the lawn mowing operation is completed, the edge cutting operation is implemented. Alternatively, at each point in the vicinity of the boundary of the area where the lawns are growing, after the edge cutting operation is completed, the lawn mowing operation is implemented.
However, in recent years, there have been cases where a lawn mower that automatically implements a lawn mowing operation and an edge cutter that automatically implements an edge cutting operation are used. In such a case, the timing of starting the edge cutting operation is unknown, and the edge cutting operation may be delayed. Similarly, in such a case, the timing of starting the lawn mowing operation is unknown, and the lawn mowing operation may be delayed. Furthermore, these situations may occur even when an operator operates a lawn mower or an edge cutter to maintain a lawn. In addition, these situations may occur not only in the case of maintaining a lawn but also in the case of maintaining a grass field where plants other than the lawn are growing.

(12) In the aspect of the above (10), the operation implementation data output unit outputs the additional operation implementation data to an operation machine that implements the additional operation.
(13) In any one of the aspects of the above (1) to (12), the operation implementation data output unit outputs the operation implementation data which prompts implementation of the second operation using an operation machine having a cut width smaller than the operation machine that implements the first operation.

According to the above (13), by prompting implementation of the second operation using an operation machine having a cut width smaller than the operation machine that implements the first operation, even if the boundary of the area where lawns are planted has a complicated shape, it is possible to prompt the second operation to be accurately implemented along the boundary.
An operation management system according to the embodiment will be described with reference to
The lawn mower 11 is a device used for implementing a lawn mowing operation. The lawn mowing operation is an operation of cutting lawns short in an area other than the vicinity of the boundary in the area where the lawns are planted. In addition, the lawn mower 11 may be an operation machine operated by an operator who implements the lawn mowing operation, or may be an operation machine that autonomously operates to implement the lawn mowing operation. The terminal 12 is, for example, a smartphone or a tablet including a touch panel display, and is carried by the operator who implements the lawn mowing operation.
The edge cutter 21 is a device used for implementing an edge cutting operation. The edge cutting operation is an operation of cutting lawns short in the vicinity of the boundary in the area where the lawns are planted. The edge cutting operation is an operation different from the lawn mowing operation because the lawn planted in the area extends and is sometimes on a curbstone or the like defining the boundary. The edge cutter 21 includes a disk-shaped cutting portion having a blade formed at an edge, and moves in the vicinity of the boundary of the area where the lawns are planted while rotating the cutting portion to cut the lawns. In addition, the surface including the main surface of the disk-shaped cut portion may intersect the surface on which the lawns to be cut by the edge cutter 21 are planted, or may be parallel to the surface on which the lawns to be cut by the edge cutter 21 are planted. In addition, the edge cutter 21 may be an operation machine operated by an operator who implements the edge cutting operation, or may be an operation machine that autonomously operates to implement the edge cutting operation. The terminal 22 is, for example, a smartphone or a tablet including a touch panel display, and is carried by the operator who implements the edge cutting operation.
The blower operation machine 31 is a device used for implementing a blower operation. The blower operation includes at least one of an operation of sucking cut lawns generated by cutting the lawns by the lawn mowing operation or the edge cutting operation and an operation of blowing the cut lawns back to the area where the lawns are planted. In addition, the blower operation machine 31 may be an operation machine operated by an operator who implements the blower operation, or may be an operation machine that autonomously operates to implement the blower operation. The terminal 32 is, for example, a smartphone or a tablet, and a blower operation is carried by the operator.
As illustrated in
These components are realized by, for example, a hardware processor such as a central processing unit (CPU) executing a program. At least a part of these components may be realized by a 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 by software and hardware in cooperation. The program may be stored in advance in a storage device (a storage device including a non-transitory storage medium) such as a hard disk drive (HDD) or a flash memory, or may be stored in a detachable storage medium (a non-transitory storage medium) such as a DVD or a CD-ROM and installed in the storage device when inserted into a drive device.
The operation completion data acquisition unit 41 acquires first operation completion data indicating that a first operation related to maintenance of a lawn has been completed. The first operation referred to herein is, for example, a lawn mowing operation or an edge cutting operation. When the first operation is a lawn mowing operation, for example, the operation completion data acquisition unit 41 acquires the first operation completion data from the lawn mower 11 or the terminal 12. Also, when the first operation is an edge cutting operation, for example, the operation completion data acquisition unit 41 acquires the first operation completion data from the edge cutter 21 or the terminal 22. Further, the operation completion data acquisition unit 41 determines whether or not the first operation completion data is acquired.
Moreover, the first operation completion data may be data indicating a first operation completion area where the first operation has been completed. For example, the first operation completion data is data generated on the basis of a path along which the lawn mower 11, the terminal 12, the edge cutter 21, or the terminal 22 has moved. Further, these paths are specified using, for example, a global positioning system (GPS) function mounted on the lawn mower 11, the terminal 12, the edge cutter 21, or the terminal 22.
The area L is an area where lawns are planted and an operation related to the maintenance of a lawn is implemented, and is defined by the boundary B. Also, an area region sandwiched between a portion between the point S and the point M and the curve C in the boundary B is an example of the first operation completion area described above.
On the basis of the first operation completion area indicated by the first operation completion data, the boundary data generation unit 42 specifies a boundary of the first operation area where the first operation is implemented or a boundary of an area adjacent to the first operation completion area, and generates boundary data indicating at least one of these boundaries. The first operation area referred to herein is, for example, an area L illustrated in
For example, when the first operation is a lawn mowing operation, the terminal 12 displays the area L and a map around the area L on the touch panel display, and the terminal 12 accepts an operation of tracing a boundary of the area L with a finger by the operator who implements the lawn mowing operation.
Next, the lawn mower 11 acquires, for example, data indicating a boundary of the area L from the terminal 12, sets a path on which the lawn mower 11 travels while implementing the lawn mowing operation, and implements the lawn mowing operation while recording a path through which the lawn mower 11 passes by using a GPS and Visual Simultaneous Localization And Mapping (V-SLAM). In addition, the lawn mower 11 records data indicating that the lawn mowing operation has been completed in association with a cell corresponding to the path on which the lawn mower 11 has traveled among cells included in the area L and the map around the area L. The data is, for example, “1”. The lawn mower 11 recognizes an area associated with the data as the first operation completion area.
The boundary data generation unit 42 acquires data indicating the path on which the lawn mower 11 has traveled while implementing the lawn mowing operation, and generates first operation completion data indicating the first operation completion area on the basis of the data. Then, the boundary data generation unit 42 specifies a cell adjacent to a cell associated with the data indicating that the lawn mowing operation has been completed among cells adjacent to a cell through which the boundary of the first operation completion area passes, thereby specifying the boundary adjacent to the locus. An example of the boundary is a portion sandwiched between the point S and the point M in the boundary of the area L illustrated in
Further, boundary data indicating a boundary in contact with a non-operation area adjacent to the first operation completion area may be generated. The non-operation area referred to herein is an area surrounded by the first operation area, where lawns are not planted due to arrangement of artificial objects such as buildings and objects or natural obstacles such as ponds, trees, and rocks, and is, for example, the non-operation area N1 and the non-operation area N2 illustrated in
In a case where the first operation completion data is acquired, the operation implementation data output unit 43 outputs operation implementation data which prompts implementation of a second operation that is an operation related to the maintenance of a lawn and is different from the first operation. The second operation referred to herein is, for example, an edge cutting operation when the first operation is a lawn mowing operation, and is a lawn mowing operation when the first operation is an edge cutting operation. When the second operation is an edge cutting operation, the operation implementation data output unit 43 outputs the operation implementation data to the edge cutter 21 or the terminal 22. Also, when the second operation is a lawn mowing operation, the operation implementation data output unit 43 outputs the operation implementation data to the lawn mower 11 or the terminal 12.
In addition, the operation implementation data output unit 43 may output operation implementation data which prompts implementation of the second operation in an area where the distance from the boundary indicated by the boundary data is equal to or less than a predetermined distance and which is included in the first operation completion area or in an area adjacent to the first operation completion area. The area is, for example, an area sandwiched between a portion between the point S and the point M and the curve C1 in the boundary B illustrated in
Further, when there is a second operation non-implemented area that is adjacent to the boundary indicated by the boundary data and in which the second operation is not implemented, the operation implementation data output unit 43 may output operation implementation data which prompts preferential implementation of the second operation in the second operation non-implemented area. The second operation non-implemented area is, for example, an area indicated by dot hatching in
Furthermore, the operation implementation data output unit 43 may output operation implementation data which prompts implementation of the second operation using an operation machine having a cut width smaller than the operation machine that implements the first operation. The cut width referred to herein is a width at which the lawn is cut in a direction perpendicular to a direction in which the operation machine moves.
The operation situation data acquisition unit 44 acquires first operation situation data indicating a situation of the first operation implemented in the first operation completion area indicated by the first operation completion data. The first operation situation data is generated, for example, on the basis of lawns depicted in a still image or a moving image captured using a camera mounted on an operation machine which implements the second operation, a camera carried by an operator who implements the second operation, or a camera mounted on the terminal. For example, the first operation situation data may be generated by using a difference between a color of an area where a relatively large amount of uncut lawns is depicted in the still image or the moving image and a color of an area where a relatively small amount of uncut lawns is depicted.
When the situation of the first operation indicated by the first operation situation data satisfies a predetermined condition, the operation reimplementation data output unit 45 outputs operation reimplementation data which prompts reimplementation of the first operation. The predetermined condition referred to herein is, for example, that a statistical value such as an average value of lengths of lawns depicted in the still image or the moving image obtained by imaging the first operation completion area described above exceeds a predetermined length. In addition, the operation reimplementation data output unit 45 outputs the operation reimplementation data to the lawn mower 11 or the terminal 12. Further, the operation reimplementation data output unit 45 determines whether or not the situation of the first operation indicated by the first operation situation data satisfies a predetermined condition.
Also, the operation completion data acquisition unit 41 may further acquire second operation completion data indicating that the second operation has been completed. In this case, the operation completion data acquisition unit 41 determines whether or not the second operation completion data has been acquired. Furthermore, in this case, the operation implementation data output unit 43 outputs additional operation implementation data which prompts implementation of an additional operation different from the first operation and the second operation to the blower operation machine 31 or the terminal 32. The additional operation referred to herein is, for example, the blower operation described above.
Next, an example of processing performed by an operation management device according to the embodiment will be described with reference to
In step S11, the operation completion data acquisition unit 41 determines whether or not the first operation completion data has been acquired. When the operation completion data acquisition unit 41 determines that the first operation completion data has been acquired (step S11: YES), the processing proceeds to step S12. On the other hand, when the operation completion data acquisition unit 41 determines that the first operation completion data has not been acquired (step S11: NO), the processing waits until it is determined that the first operation completion data has been acquired.
In step S12, the boundary data generation unit 42 generates the boundary data indicating a boundary.
In step S13, the operation implementation data output unit 43 outputs the operation implementation data.
Next, an example of processing performed by an operation management device according to the embodiment will be described with reference to
In step S21, the operation situation data acquisition unit 44 acquires the first operation situation data.
In step S22, the operation reimplementation data output unit 45 determines whether or not the situation of the first operation indicated by the first operation situation data satisfies a predetermined condition. When the operation reimplementation data output unit 45 determines that the situation of the first operation indicated by the first operation situation data satisfies the predetermined condition (step S22: YES), the processing proceeds to step S23. On the other hand, when the operation reimplementation data output unit 45 determines that the situation of the first operation indicated by the first operation situation data does not satisfy the predetermined condition (step S22: NO), the processing is completed.
In step S23, the operation reimplementation data output unit 45 outputs the operation reimplementation data.
Next, an example of processing performed by an operation management device according to the embodiment will be described with reference to
In step S31, the operation completion data acquisition unit 41 determines whether or not the second operation completion data has been acquired. When the operation completion data acquisition unit 41 determines that the second operation completion data has been acquired (step S31: YES), the processing proceeds to step S32. On the other hand, when the operation completion data acquisition unit 41 determines that the second operation completion data has not been acquired (step S31: NO), the processing waits until it is determined that the second operation completion data has been acquired.
In step S32, the operation implementation data output unit 43 outputs the additional operation implementation data.
The operation management system 1 according to the embodiment has been described above focusing on the operation management device 40.
When the first operation completion data is acquired, the operation management device 40 outputs operation implementation data which prompts implementation of a second operation that is an operation related to the maintenance of a lawn and is different from the first operation. As a result, the operation management device 40 prompts implementation of the second operation after the second operation becomes implementable, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 acquires first operation completion data indicating a first operation completion area in which the first operation has been completed, generates boundary data indicating a boundary of the first operation area, and outputs operation implementation data which prompts implementation of the second operation in an area where the distance from the boundary indicated by the boundary data is equal to or less than a predetermined distance and which is included in the first operation completion area or in an area adjacent to the first operation completion area. As a result, the operation management device 40 prompts implementation of the second operation in the area where the second operation can be implemented, so that the maintenance of a lawn can be efficiently implemented.
In addition, when there is a second operation non-implemented area that is adjacent to the boundary indicated by the boundary data and in which the second operation is not implemented, the operation management device 40 outputs operation implementation data which prompts preferential implementation of the second operation in the second operation non-implemented area. As a result, the operation management device 40 expands the area where the second operation can be implemented at an early stage, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 generates boundary data indicating a boundary in contact with a non-operation area adjacent to the first operation completion area. As a result, the operation management device 40 prompts implementation of the second operation after more accurately grasping the area where the second operation can be implemented, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 outputs operation implementation data to the terminal 12 or the terminal 22. As a result, the operation management device 40 transmits an information that the second operation can be started to an operator in charge of implementing the second operation to prompt implementation of the second operation, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 outputs operation implementation data to the lawn mower 11 or the edge cutter 21. As a result, the operation management device 40 transmits an information that the second operation can be started to the operation machine that implements the second operation to prompt implementation of the second operation, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 acquires first operation situation data indicating a situation of the first operation implemented in the first operation completion area indicated by the first operation completion data, and when the situation of the first operation indicated by the first operation situation data satisfies a predetermined condition, outputs operation reimplementation data which prompts reimplementation of the first operation. As a result, the operation management device 40 corrects the maintenance state of a portion where the first operation is not sufficiently implemented, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 outputs the operation reimplementation data to the terminal 12. As a result, the operation management device 40 transmits an information that the first operation should be implemented again to an operator in charge of implementing the first operation, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 outputs the operation reimplementation data to the lawn mower 11 or the edge cutter 21. As a result, the operation management device 40 transmits an information that the first operation should be implemented again to the operation machine that implements the first operation, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 further acquires second operation completion data indicating that the second operation has been completed, and when the second operation completion data is acquired, the operation management device 40 outputs additional operation implementation data which prompts implementation of an additional operation different from the first operation and the second operation. As a result, the operation management device 40 prompts to implement the additional operation different from the first operation and the second operation, so that it is possible to efficiently implement the maintenance of a lawn including the implementation of the additional operation.
In addition, the operation management device 40 outputs the additional operation implementation data to the terminal 32. As a result, the operation management device 40 prompts an operator in charge of implementing the additional operation to implement the additional operation, so that it is possible to efficiently implement the maintenance of a lawn including the implementation of the additional operation.
In addition, the operation management device 40 outputs the additional operation implementation data to the operation machine that implements the additional operation. As a result, the operation management device 40 prompts an additional operation machine to implement the additional operation, so that the maintenance of a lawn can be efficiently implemented.
In addition, the operation management device 40 outputs operation implementation data which prompts implementation of the second operation using an operation machine having a cut width smaller than the operation machine that implements the first operation. As a result, even if the boundary of the area where lawns are planted has a complicated shape, the operation management device 40 can prompt the second operation to be accurately implemented along the boundary.
In the embodiment described above, the maintenance of a lawn has been described as an example, but the present invention is not limited thereto. The operation management device 40 can be applied not only to the maintenance of a lawn but also to overall maintenance of a grass field. In addition, the grass field referred to herein includes not only an area where lawns are planted but also an area where plants other than lawns are grown. Furthermore, examples of the area where plants other than lawns are grown include parks, open lots, and riverbeds.
Further, in the embodiment described above, the case where the lawn mowing operation is implemented using the lawn mower 11 and the edge cutting operation is implemented using the edge cutter 21 has been described as an example, but the present invention is not limited thereto. That is, the lawn mowing operation and the edge cutting operation may be implemented by an operation machine having both the function of the lawn mower 11 and the function of the edge cutter 21.
In addition, in the embodiment described above, the case where the operation management device 40 is realized by the server has been described as an example, but the present invention is not limited thereto. For example, the operation management device 40 may be incorporated in the lawn mower 11, the edge cutter 21, or the blower operation machine 31.
In addition, in the embodiment described above, the case where all the functions of the operation management device 40 are realized by one device has been described as an example, but the present invention is not limited thereto. That is, the operation management device 40 may be realized by a plurality of devices, and each device may realize a part of the functions described above.
While the modes for carrying out the present invention have been described above using the embodiment, the present invention is not limited to the embodiment described above, and various modifications and substitutions are possible without departing from the gist of the present invention.
