Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiments are examples that embody the present invention, and are not intended to limit the technical scope of the present invention.

(Embodiment 1)
[1] Overall Configuration As shown in FIG. 1, the work management system 1 according to the present embodiment includes a management server 2, a user terminal 3, and a combine 4. The combine 4 is an example of a work machine to be managed by the work management system 1.

The "working machine" as used in the present disclosure means various working machines that move in the field F1, and as an example, is a work vehicle such as a combine 4, a tractor, a rice transplanter, and a seeding machine. That is, the work machine includes the work vehicle. The work machine is not limited to a "vehicle" such as a combine 4, a tractor, a rice transplanter, and a seeder, and may be, for example, a work projectile such as a drone for pesticide spraying or fertilization or a multicopter. Further, the work machine is not limited to the agricultural machine (agricultural machine), and may be, for example, a construction machine (construction machine) or the like.

Further, the "field" referred to in the present disclosure is a work target area where various operations such as harvesting, planting (rice planting) or fertilization are performed while the work machine is moving, and is a field or field for growing agricultural products. Includes orchards and pastures. Further, when the plants are grown in the plantation field, the plantation field becomes the field F1, and when the trees to be wood are grown in the forest as in the forestry, the forest becomes the field F1. Since such a field F1 is a specific place in a real space (existing space), the position, shape, size, and the like are represented by, for example, latitude and longitude. In the present embodiment, the case where the work target area for performing various tasks while the work machine moves in the real space is the field F1 will be described, but the work target area may be other than the field F1. .. For example, if the work machine is a construction machine, the work site where the construction machine works is the work target area.

In the present embodiment, the work machine (combine 4) to be managed by the work management system 1 is included in the components of the work management system 1, but the work machine is a component of the work management system 1. It is not mandatory to be included. Similarly, in the present embodiment, the user terminal 3 is included in the component of the work management system 1, but it is not essential that the user terminal 3 is included in the component of the work management system 1. That is, the work management system 1 does not have to include at least one of the work machine (combine 4) and the user terminal 3 as a component. When the work management system 1 does not include both the work machine and the user terminal 3 in the components, the work management system 1 includes only the management server 2 in the components.

The management server 2, the user terminal 3, and the combine 4 (working machine) can communicate with each other. "Communicable" as used in the present disclosure means direct communication or via a communication network (network) N1 or a repeater by an appropriate communication method of wired communication or wireless communication (communication using radio waves or light as a medium). It means that information can be exchanged indirectly. For example, the management server 2 and the combine 4 can communicate via a mobile phone line network, a packet line network, a wireless LAN (Local Area Network), or the like. Further, the management server 2 and the user terminal 3 can communicate with each other via the Internet, LAN, WAN (Wide Area Network), a public telephone line, or the like. The communication means between the management server 2, the user terminal 3, and the combine 4 is not limited to the above example, and is realized by an appropriate communication means. Further, it is not an essential configuration in the work management system 1 that the management server 2, the user terminal 3, and the work machine (combine 4) can communicate with each other. For example, even if there is no communication function between the management server 2 and the work machine (combine 4), information is recorded on a non-temporary recording medium that can be read by a computer on the work machine, and the management server 2 records the information from the recording medium. By reading the information, it is possible to exchange information offline.

The work machine (combine 4) capable of communicating with the management server 2, that is, the work machine to be managed by the work management system 1, may be one or a plurality of machines. When the work machines to be managed by the work management system 1 include a plurality of combine harvesters 4, the plurality of combine harvesters 4 cooperate with each other in harvesting operations for harvesting crops in the same field F1, for example. Execute. Further, the plurality of work machines to be managed by the work management system 1 may include different types of work machines such as a combine 4, a tractor, a rice transplanter and a sowing machine.

In the present embodiment, the management server 2 has a core function of the work management system 1. That is, the management server 2 has a function of managing the work of the work machine (here, the combine 4). The user terminal 3 is a communication terminal used by the user. For example, the user accesses the website of the work support service provided by the management server 2 (for example, the “work support site”) on the user terminal 3, and includes information such as the operation status and the yield of the combine 4. It is possible to display a web page.

[2] Working Machine Next, the configuration of the combine 4, which is an example of the working machine, will be described in detail with reference to FIGS. 1, 2, and 3. The combine 4 includes a traveling device 41, a harvesting device 42, a threshing device 43, a sorting device 44, a storage device 45, a power device 46, a driving unit 47, a vehicle control device 48, a mounting terminal 49, and the like.

The vehicle control device 48 is a computer system having one or more processors and one or more memories such as a non-volatile memory and a RAM (Random Access Memory). Then, the vehicle control device 48 controls the operation of the combine 4 in response to various user operations on the combine 4.

The traveling device 41 can move the combine 4 in the front-rear direction and the left-right direction. For example, as shown in FIG. 4, the combine 4 carries out the harvesting operation while meandering in the field F1. In FIG. 4, as an example, two fields F1 of the first field F11 and the second field F12 are shown as the fields F1 in which the combine 4 working machine works. Further, in FIG. 4, a schematic map including the field F1 is shown in the upper row, and a schematic enlarged view of the field F1 (first field F11) is shown in the lower row (inside the balloon). The movement locus R1 of the combine 4 is not limited to the path shown in FIG. As an example, a working machine such as a combine 4 may move while turning right (or left) from the outside to the inside in the field F1, in which case the movement locus R1 becomes a spiral path.

The reaping device 42 cuts the culm of the field F1. The cutting device 42 includes a reel 421, a cutter 422, an auger 423, a conveyor 424, a rotor 425, and the like. The reel 421 guides the grain culm of the field F1 to the cutter 422 by rotating. The cutter 422 cuts the grain guided by the reel 421. The auger 423 is a lateral feed screw that collects the culms cut by the cutter 422 in a predetermined position.

The conveyor 424 transports the culms collected by the auger 423 to the rotor 425. The rotor 425 sends the grain culms conveyed by the transfer conveyor 424 to the threshing device 43.

The threshing device 43 performs a threshing process on the grain culms cut by the cutting device 42. The threshing process separates the threshing containing the grains from the culm. The threshing falls from the threshing device 43 to the lower sorting device 44.

The sorting device 44 executes a sorting process for sorting grains from the threshing that falls from the threshing device 43. The sorting device 44 sorts the threshing grains from the threshing, for example, by sieving the threshing while blowing wind from diagonally below the threshing.

The threshing device 43, for example, performs a threshing process on the grain culm while transporting the grain culm from the front part to the rear of the grain culm. Similarly, the sorting device 44 performs a sorting process for threshing, for example, while transporting the threshing device from the front to the rear of the sorting device 44.

The storage device 45 includes a vertical transfer duct 451, a vertical transfer conveyor 452, a grain tank 453, a discharge auger 454, and the like. The vertical transfer duct 451 is a duct that connects the sorting device 44 and the upper inlet of the Glen tank 453. The vertical conveyor 452 is a screw conveyor that transfers grains from the sorting device 44 into the grain tank 453 by rotating in the vertical conveyor duct 451. The discharge auger 454 discharges the grains in the grain tank 453 to an arbitrary place around the combine 4.

The power device 46 is a drive source for the traveling device 41, the harvesting device 42, the threshing device 43, the sorting device 44, and the storage device 45. The power device 46 has an engine such as a diesel engine as a power source. Further, the power device 46 may have a motor (motor) as a power source, or may have a hybrid power source including an engine and a motor.

The driver unit 47 is provided with a driver's seat in which the operator sits, and operation devices such as a steering wheel operated by the operator, various operation levers, and various operation switches. For example, the operating device includes an engine ON / OFF key. The engine ON / OFF key is a key switch, a button switch, or the like for switching between starting and stopping the engine mounted on the combine 4. The vehicle control device 48 starts the engine when the engine ON / OFF key is switched on, and stops the engine when the engine ON / OFF key is switched off.

The on-board terminal 49 is a communication terminal mounted on the work machine (combine 4). The on-board terminal 49 has functional units such as a control unit 491, a storage unit 492, a communication unit 493, a position detection unit 494, and a performance detection unit 495. These plurality of functional units included in the mounted terminal 49 may be distributed in a plurality of housings or may be provided in one housing. In the present embodiment, as an example, the position detection unit 494 and the performance detection unit 495 are provided in a housing separate from other functional units (control unit 491 and the like).

The control unit 491 is a computer system having one or more processors and one or more storage memories such as a non-volatile memory and RAM. The storage unit 492 is a control program for causing the control unit 491 to execute a predetermined process, a non-volatile memory for storing data such as work information D1 (see FIG. 5) described later, and the like.

The communication unit 493 can transmit and receive various data to and from the vehicle control device 48 by short-range wireless communication or wired communication. Specifically, the control unit 491 can acquire operation information indicating various operation states of the combine 4 from the vehicle control device 48 by the communication unit 493. The operation information is included in the work information D1 related to the work of the work machine (combine 4).

The operation information includes information on at least one item of the operation status of the work machine (combine 4) itself. For example, the operation information includes steering wheel operation information indicating a steering wheel operation angle (steering angle), shift information indicating an operation state of a shift lever, and the like. The operation information also includes engine information indicating the ON / OFF state of the engine ON / OFF key of the combine 4. Further, the operation information includes rotation speed information indicating the engine rotation speed, vehicle speed information, fuel consumption information indicating the fuel consumption rate, load information indicating the engine load, and the like. In addition, the operation information includes slip rate information indicating the slip rate, clutch information indicating the clutch operation state, brake information indicating the brake operation state, the state of various sensors mounted on the work machine, and the like. May be good.

The "work information" here includes, in addition to the operation information, the position information D2 indicating the position of the work machine, the actual information indicating the actual result of the work by the work machine, and the like. The control unit 491 can acquire the position information D2 of the work information D1 from the position detection unit 494. The control unit 491 can acquire the actual information in the work information D1 from the actual detection unit 495. The "result information" here is information related to the result (result) of the work performed by the work machine, for example, when the work machine is a harvester (including the combine 4) for harvesting crops. , Includes harvest information (yield data) regarding yield (yield). That is, in this case, the work information D1 includes the crop yield information in the work machine for each position of the work machine. In addition, the actual information may include information such as average work speed, variation in work speed, work time, work efficiency (area / work time), fertilizer application amount, planting depth, tillage depth and lift angle. ..

Further, the communication unit 493 can send and receive various data to and from the management server 2 via the communication network N1. Therefore, the on-board terminal 49 mounted on the combine 4 (working machine) can transmit, for example, work information D1 or the like to the management server 2 via the communication network N1.

The position detection unit 494 uses, for example, a satellite positioning system such as GNSS (Global Navigation Satellite System) to detect the position of the mounted terminal 49, that is, the position information D2 indicating the position of the combine 4 on which the mounted terminal 49 is mounted. .. The position information D2 includes latitude and longitude information indicating the position of the combine 4. The method for acquiring the position information D2 of the combine 4 by the position detection unit 494 is not particularly limited. Further, the position information D2 is not limited to a format using latitude and longitude, and may be a format other than latitude and longitude as long as it can specify the position of the work machine (here, combine 4).

Here, considering the processing in the management server 2, it is preferable that the position detection unit 494 detects the position information D2 with as high accuracy as possible. As an example, it is preferable that the position detection unit 494 adopts a method capable of detecting the position information D2 with relatively high accuracy, such as RKT (Real Time Kinematic) positioning. This has the advantage that, for example, when the work area A1 (see FIG. 6) is automatically set on the management server 2 as described later, the work area A1 can be set accurately.

The performance detection unit 495 detects the performance information included in the work information D1. Here, since the working machine is a harvester (combine 4) for harvesting crops, the actual information includes the harvest amount information (yield data) regarding the harvest amount. Therefore, the performance detection unit 495 has a sensor (grain sensor) for detecting the yield (grain amount) of the crop harvested by the combine 4. The performance detection unit 495 is attached to the upper surface of the Glen tank 453 as an example (see FIG. 3). The grains obtained by the threshing device 43 and the sorting device 44 are transported toward the Glen tank 453 by the vertical transfer conveyor 452. As an example, the grain sensor of the performance detection unit 495 includes an impact detection unit such as a strain gauge or a piezoelectric element, and detects an impact force when the conveyed grain collides with the impact detection unit. The performance detection unit 495 detects the yield (detection value) based on this impact force. The method for acquiring the yield of combine 4 by the performance detection unit 495 is not particularly limited.

The control unit 491 executes the following various processes. Specifically, the control unit 491 executes a timekeeping process for measuring the current time. The "time" here includes a year, a month, a day, an hour, a minute, and a second. The on-board terminal 49 is connected to a battery, and the control unit 491 can execute processing such as timekeeping processing by the electric power supplied from the battery even when the engine of the combine 4 is in the OFF state.

Further, the control unit 491 executes an information acquisition process for acquiring the position information D2 of the work machine (combine 4), the actual information (harvest amount information, etc.) and the operation information. Specifically, the control unit 491 periodically or irregularly performs the position information D2, the actual information, and the operation at a predetermined time interval or a predetermined timing (time) based on the time measured by the timekeeping process. Get information. In the present embodiment, as an example, the control unit 491 periodically acquires the position information D2, the actual information, and the operation information at a preset (predetermined) sampling interval.

The control unit 491 records the acquired position information D2, actual information, and operation information in the storage unit 492. Here, the control unit 491 stores the position information D2, the actual information, and the operation information in the storage unit 492 in association with the time information representing the time when these are acquired. Therefore, the position information D2, the actual information, and the operation information acquired at the same time are maintained in a state of being associated with each other by using the acquired time information as a key in the storage unit 492. The sampling interval is set at least based on the acquisition interval (for example, a time interval of 1 second or more and 5 seconds or less) of actual information (harvest amount information) required for creating the map M1 (see FIG. 9). Further, the sampling interval is set to be shorter than the acquisition interval (for example, 1 minute interval) of the position information D2 required for specifying the movement locus R1 of the combine 4, for example. In the present embodiment, as an example, the control unit 491 acquires position information D2, actual information, and operation information at a sampling interval of “5 seconds”.

FIG. 5 is a diagram showing an example of work information D1 including position information D2, actual information (harvest amount information), operation information, and time information recorded in the storage unit 492. Since the work information D1 is acquired at sampling intervals (here, 5 second intervals), the information shown in each row of the table shown in FIG. 5 is the work information D1. That is, the entire table shown in FIG. 5 includes a plurality of work information D1s. Regarding the position information D2, the information shown in each row of the “position information” column of the table shown in FIG. 5 is the position information D2. That is, the entire table shown in FIG. 5 includes a plurality of position information D2. However, in FIG. 5, one reference code “D2” is attached to the plurality of position information D2.

In FIG. 5, the position information D2 is indicated by X1 to X17 and Y1 to Y17, but the actual position information D2 includes numerical values (latitude and) indicating the position of the combine 4 instead of X1 to X17 and Y1 to Y17. (Longitude) etc. are included. Further, in FIG. 5, the harvest amount information as the actual result information is shown by E1 to E17, but the actual harvest amount information is a numerical value indicating the detection value detected by the actual result detection unit 495 instead of E1 to E17. (Weight) etc. are included. Further, in FIG. 5, vehicle speed information (an example of operation information) is shown by V1 to V17, but the actual vehicle speed information is a numerical value (speed) indicating a detection value detected by the vehicle speed sensor instead of V1 to V17. ) Etc. are included.

As an example in this embodiment, the control unit 491 periodically acquires position information D2, actual information (harvest amount information), and operation information while the engine ON / OFF key of the combine 4 is ON and the engine is ON. Then, the information recording process to be recorded in the storage unit 492 is repeatedly executed. Therefore, the control unit 491 can acquire a plurality of work information D1s related to the work for each position of the work machine during the "work period" in which the combine 4 which is the work machine is used.

Further, as an example in the present embodiment, the control unit 491 ends the information recording process when the engine ON / OFF key of the combine 4 is switched off and the engine is turned off (that is, stopped). That is, if the engine is in the off state, new work information D1 (position information D2, actual information, operation information, and time information) is not stored in the storage unit 492. Further, the control unit 491 transmits one or more work information D1 recorded in the storage unit 492 to the management server 2 at the time when the information recording process is completed. Here, when the control unit 491 receives the reception confirmation signal of the work information D1 from the management server 2, the control unit 491 erases the work information D1 from the storage unit 492. That is, when the work information D1 is normally transmitted from the combine 4 (work machine) to the management server 2, the work information D1 in the storage unit 492 is erased.

As described above, the combine 4 includes the on-board terminal 49, records the work information D2 including the position information D2 according to the work, the actual result information (harvest amount information), and the operation information in the storage unit 492, and stores the work information D1 in the storage unit 492. The one or more work information D1s that have been created are transmitted to the management server 2. In the present embodiment, the work information D1 is transmitted from the work machine to the management server 2 triggered by the switching of the engine of the combine 4 as the work machine from the on state to the off state (that is, stop), but the management server 2 The transmission timing of the work information D1 to is not limited to this example. For example, the combine 4 may send the work information D1 obtained in the previous work period to the management server 2 periodically or periodically, triggered by the engine switching from the off state to the on state (that is, starting). The work information D1 may be transmitted to the management server 2 irregularly.

Further, the work machine to be managed by the work management system 1 is not limited to the combine 4, and may be, for example, a tractor, a rice transplanter, a sowing machine, or the like. Then, if the work machine is changed, naturally, the functions of each part such as the cutting device 42 in the work machine are changed according to the work machine. On the other hand, the basic functions of the mounted terminal 49 mounted on the work machine are common regardless of the work machine.

That is, regardless of the work machine, the mounted terminal 49 has a control unit 491, a storage unit 492, a communication unit 493, a position detection unit 494, a performance detection unit 495, and the like. However, for example, when the work machine is a tractor, the actual information in the work information related to the work of the work machine includes, in addition to or instead of the yield information, soil information regarding soil characteristics, fertilizer application information regarding fertilizer application amount, etc. Data may be included. In this case, the performance detection unit 495 detects soil data, fertilization data, etc. in addition to or in place of the yield information (yield data). Similarly, for example, when the work machine is a rice transplanter, the actual information in the work information related to the work of the work machine may include data such as fertilizer application information regarding the fertilizer application amount. In this case, the performance detection unit 495 detects fertilizer application data and the like. Similarly, for example, when the work machine is a seeding machine, the actual information in the work information related to the work of the work machine may include data such as seeding information regarding the seeding amount. In this case, the performance detection unit 495 detects the seeding data and the like.

If the work machine is a tractor, the work machine can perform multiple types of work such as tilling, mowing, or spraying fertilizer, pesticides, or seeds by changing the implant attached to the tractor body. It is possible. When the type (contents) of work that can be performed by the work machine is changed, such as when the implant attached to the tractor body is changed, the work machines before and after the change must be different work machines. do. That is, the "different work machines" referred to in the present disclosure include, for example, different types of work machines such as the combine 4 and the rice transplanter, and work machines having different types of work that can be performed.

[3] Management Server Next, the configuration of the management server 2 will be described in detail with reference to FIG. The management server 2 is a server including an information processing unit 21, a data storage unit 22, an operation reception unit 23, a (server side) communication unit 24, and the like. The management server 2 is not limited to one computer, and may be a computer system in which a plurality of computers operate in cooperation with each other. Further, various processes executed by the management server 2 may be distributed and executed by a plurality of processors.

The communication unit 24 is a communication interface having a communication function with one or more work machines (combines 4) and external devices such as a user terminal 3. Specifically, the communication unit 24 connects the management server 2 to the communication network N1 by wire or wirelessly, and connects the management server 2 with one or more work machines (combine 4), the user terminal 3, and the like via the communication network N1. Performs data communication according to a predetermined communication protocol.

The operation reception unit 23 accepts the user's operation. Specifically, since the management server 2 can communicate with the user terminal 3, the operation reception unit 23 transmits an operation signal corresponding to the user's operation to the user terminal 3 from the user terminal 3, so that the user can use the operation reception unit 23. Accept operations indirectly. That is, when the user operates the user terminal 3, the user terminal 3 generates an operation signal corresponding to the user's operation, and the operation signal is transmitted from the user terminal 3 to the management server 2. Therefore, the operation receiving unit 23 can receive the user's operation by the operation signal received from the user terminal 3 by the management server 2. Further, the operation receiving unit 23 is not limited to the user's operation on the user terminal 3, and may accept the user's operation (administrator of the management server 2 or the like) on the operation unit other than the user terminal 3. In this case, the operation unit is realized by, for example, a touch panel, a mouse, a keyboard, or the like provided in the management server 2 or attached to the management server 2.

The data storage unit 22 includes a non-volatile storage device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) that stores various types of information. The data storage unit 22 stores (stores) a control program such as a work management program for causing the information processing unit 21 to execute the work management method described later. The work management program is, for example, recorded and provided on a computer-readable non-temporary recording medium, read from the non-temporary recording medium by the reading device of the management server 2, and stored in the data storage unit 22. The work management program may be provided (downloaded) to the management server 2 from a server other than the management server 2 via a telecommunication line (communication network N1) and stored in the data storage unit 22.

Further, the data storage unit 22 includes a work information storage unit 221 and a work area storage unit 222. The work information storage unit 221 stores the work information D1 transmitted from the combine 4 (work machine). The work area storage unit 222 stores information about the work area A1 described later.

The information processing unit 21 is a computer system having one or more processors and one or more memories such as a non-volatile memory and a RAM, and executes various processes (information processing). The information processing unit 21 has functional units such as a position acquisition unit 211, a work acquisition unit 212, an area setting unit 213, a section setting unit 214, a data calculation processing unit 215, a map generation unit 216, and a display processing unit 217. These plurality of functional units included in the information processing unit 21 may be distributed in a plurality of housings or may be provided in one housing.

The position acquisition unit 211 acquires a plurality of position information D2 during the work period of the work machine (combine 4) moving in the field F1. The "work period" here is a period during which work is being performed on the work machine, and during the work period, work information D1 is acquired by the on-board terminal 49 (control unit 491) mounted on the work machine. ing. In the present embodiment, as an example, the period from when the engine ON / OFF key of the combine 4 is switched on to when it is switched off, that is, the period during which the engine is in the ON state is defined as the “working period”. Then, since the work machine moves in the field F1 during the work period, a plurality of position information D2s are acquired as the work machine moves. Further, the "working period" may include not only the period during which the work machine moves in the field F1, but also, for example, the period during which the work machine is traveling on the farm road. In short, when the period in which the engine is on is defined as the "working period" as in the present embodiment, the working period may include a period in which the working machine exists in a place other than the field F1, such as a farm road. However, among the plurality of position information D2 during the work period, the position information D2 when the work machine exists in a place other than the field F1 can be obtained by referring to, for example, vehicle speed information and clutch information in the operation information. It can be identified as unnecessary information.

Make it common. Therefore, although the information processing unit 21 has a position acquisition unit 211 for acquiring the position information D2 and a work acquisition unit 212 for acquiring the work information D1, the position acquisition unit 211 is acquired by the work acquisition unit 212. The position information D2 is acquired by extracting the position information D2 from the work information D1. As a result, the position information D2 detected by the same position detection unit 494 in the work machine is the position information D2 acquired by the position acquisition unit 211 and the position information D2 in the work information D1 acquired by the work acquisition unit 212. It is also used as.

In the present embodiment, the map generation unit 216 generates the map M1 by associating the work data (harvest amount per unit area) calculated by the data calculation processing unit 215 with the plurality of sections K. That is, for example, the map generation unit 216 generates a map M1 (yield map) representing the distribution of the yield in the field F1. According to such a map M1, the user can grasp the harvest state of the entire field F1 by checking the map M1. Such a map M1 is used, for example, for the purpose of evaluating the harvest state of the field F1 and planning the harvesting work for the next year.

[5] Work Management Method Hereinafter, an example of a work management method executed mainly by the information processing unit 21 of the management server 2 will be described with reference to FIGS. 6 to 18. Hereinafter, unless otherwise specified, it is assumed that the harvesting work by the combine 4 which is a work machine is subject to the management by the work management method.

Further, since the work management method according to the present embodiment is executed by the information processing unit 21 whose main configuration is a computer system, in other words, it is embodied in a work management program. That is, the work management program according to the present embodiment is a computer program for causing one or more processors to execute each process related to the work management method. Such a work management program may be executed in cooperation with, for example, the information processing unit 21 of the management server 2 and the control unit 491 of the combine 4.

[5.1] Work area setting process First, the "work area setting process" for setting the work area A1 will be described. In the present embodiment, there are two types of operation modes of the area setting unit 213: a first operation mode in which the work area A1 is automatically set (specified) and a second operation mode in which the work area A1 is manually set. There is a mode. Then, the area setting unit 213 can switch between the first operation mode and the second operation mode according to the user's operation accepted by the operation reception unit 23. That is, in the present embodiment, there are two types of setting methods, automatic setting and manual setting, for the setting of the work area A1. Therefore, in the following, the setting process of the work area A1 by the area setting unit 213 will be described separately for the first operation mode (automatic setting) and the second operation mode (manual setting).

[5.1.1] Automatic setting of work area First, the setting process of the work area A1 when the operation mode of the area setting unit 213 is in the first operation mode, that is, when the work area A1 is automatically set, will be described. ..

In the first operation mode, the area setting unit 213 sets the work area A1 corresponding to the field F1 based on the plurality of position information D2, for example, as shown in FIG. In FIG. 6, each position on the virtual space corresponding to the position information D2 of the work machine (combine 4) acquired at the sampling interval is indicated by a black dot mark, and the position (sampling position) of the black dot is indicated by a reference code. "D2" is attached. Further, FIG. 6 shows how two work areas A1 corresponding to the two fields F1 of the first field F11 and the second field F12 exemplified in FIG. 4 are set. That is, in FIG. 6, the first working area A11 corresponds to the first field F11, and the second working area A12 corresponds to the second field F12.

Here, as an example, it is assumed that when the combine 4 moves along the movement locus R1, the position information D2 acquired at the sampling interval is obtained during the work period. The area setting unit 213 automatically sets the work area A1 based on such a plurality of position information D2.

When setting the work area A1, the information processing unit 21 acquires a plurality of position information D2 used for setting the work area A1 by the position acquisition unit 211. In the present embodiment, the position acquisition unit 211 acquires the position information D2 by extracting the position information D2 from the work information D1 acquired by the work acquisition unit 212.

In the present embodiment, the area setting unit 213 first refers to the vehicle speed information, the clutch information, and the like in the operation information for the plurality of position information D2, and obtains the position information D2 of the work machine that is not related to the work (for example, the harvesting work). Exclude as unnecessary information. Further, the area setting unit 213 excludes the position information D2 of the work machine not related to the work as unnecessary information due to the vicinity of K, the point density, or the like. Then, with respect to the plurality of position information D2 remaining after excluding unnecessary information, the area setting unit 213 groups the position information D2 whose temporal and / or spatial intervals are equal to or less than a predetermined value, and groups the plurality of position information D2. Extract a set of. By such a process, a set of a plurality of position information D2 relating to the position of the work machine during the execution of the work, that is, during the work period is extracted. The plurality of position information D2 included in such a set are scattered on the movement locus R1 of the work machine in the field F1.

The area setting unit 213 sets (specifies) the work area A1 corresponding to the field F1 in which the work machine is presumed to have actually performed the work by using the set of the extracted plurality of position information D2. In the present embodiment, the area setting unit 213 uses the convex hull processing for the point cloud in the virtual space corresponding to each position of the work machine (combine 4) specified by the position information D2 to set the work area A1. Set. As a result, a convex hull, which is a figure that covers the point cloud in the virtual space corresponding to the plurality of position information D2 without dents, that is, the smallest convex polygon that encloses the point cloud in the virtual space. , Is set as the work area A1. In short, the smallest convex polygon that surrounds the point cloud on the movement locus R1 of the work machine in the field F1 is automatically set as the work area A1.

Here, in the example of FIG. 6, the work machine that is the acquisition source of the position information D2 in the first field F11 and the work machine that is the acquisition source of the position information D2 in the second field F12 are different work machines. Is. Therefore, the area setting unit 213 sets one work area A1 from the point cloud corresponding to the position information D2 in the first field F11 by the convex hull processing, and corresponds to the position information D2 in the second field F12. From the point cloud, one work area A1 is set by the convex hull processing. By such convex hull processing, in the example of FIG. 6, the first work area A11 having substantially the same shape as the outer shape of the first field F11 is set from the point cloud corresponding to the position information D2 in the first field F11. To. Similarly, from the point cloud corresponding to the position information D2 in the second field F12, the second work area A12 having substantially the same shape as the outer shape of the second field F11 is set.

When the setting of the work area A1 is completed, the area setting unit 213 registers the work area A1 by storing the information about the set work area A1 in the work area storage unit 222. Specifically, the work area A1 is registered by storing the information necessary for reproducing the work area A1 in the virtual space in the work area storage unit 222. In the present embodiment, the information for specifying the position and shape of the work area A1 on the coordinates set in the virtual space, that is, the coordinate information of the outline of the work area A1 is stored as the information regarding the work area A1. It is stored in the unit 222. In this embodiment, as an example, the coordinates in the virtual space are associated with the latitude and longitude in the real space. Therefore, the work area A1 is registered in the work area storage unit 222 using the latitude and longitude of the corresponding field F1.

Further, in the present embodiment, the area setting unit 213 has, as information regarding the set work area A1, for example, a work name for specifying the type (content) of the work, and time information regarding the work (as an example, the start date and time and the end). The date and time) and the like are also stored in the work area storage unit 222. As a result, when registering the work area A1, the work area A1 is associated with the work name and time information of the work performed in the field F1 corresponding to the work area A1 in the work area storage unit 222. It will be stored. Therefore, for example, even for the same field F1, individual work areas A1 can be set according to the work name, the year, and the like.

[5.12] Manual setting of the work area Next, the setting process of the work area A1 when the operation mode of the area setting unit 213 is in the second operation mode, that is, when the work area A1 is manually set, will be described. do.

In the second operation mode, the area setting unit 213 sets the work area A1 corresponding to the field F1 according to the user's operation accepted by the operation reception unit 23, for example. As an example, the area setting unit 213 sets the work area A1 corresponding to the field F1 according to the operation of the user who sets the work area A1 on the registration screen Im2 as shown in FIG. 7. The registration screen Im2 includes at least one field F1. The registration screen Im2 is displayed on the display unit (operation display unit 33) of the user terminal 3, for example, on the display processing unit 217. On the registration screen Im2, the user sets the arbitrary range in the work area A1 by, for example, performing an operation of designating an arbitrary range with a cursor or the like.

That is, in the example of FIG. 7, when the user performs an operation of designating a range corresponding to the first field F11 on the registration screen Im2, the first work area A11 having substantially the same shape as the first field F11 is set. .. Similarly, when the user performs an operation of designating a range corresponding to the second field F12 on the registration screen Im2, the second work area A12 having substantially the same shape as the outer shape of the second field F11 is set. Further, on the registration screen Im2, operations such as scrolling, enlargement / reduction, and page switching can be performed according to the user's operation. Further, the designation of the work area A1 on the registration screen Im2 may be realized by inputting, for example, latitude and longitude.

Also in the second operation mode, when the setting of the work area A1 is completed, the area setting unit 213 registers the work area A1 by storing the information about the set work area A1 in the work area storage unit 222.

[5.2] Map generation process Next, a "map generation process" for generating (creating) a map M1 in which work data based on a plurality of work information D1s are associated with a plurality of sections K will be described. .. In the present embodiment, there are various methods for setting the section K by the section setting unit 214, but here, the generation process of the map M1 will be described by simply taking the case where a plurality of sections K are set as an example. ..

The map generation unit 216 generates the map M1 by associating the work data based on the plurality of work information D1 with the plurality of sections K. That is, the map generation unit 216 divides the work area A1 into a plurality of sections K, and then generates map information data regarding work data (for example, the yield per unit area) for each section K. In the present embodiment, the map generation unit 216 is a map for embodying the map M1 by associating the work data calculated by the data calculation processing unit 215 based on the plurality of work information D1 with each section K. Generate informational data. The generated map information may be included in the data table Ta1 (see FIG. 16) and stored in the data storage unit 22, for example.

As an example, the map M1 is created by dividing the entire work area A1 into a plurality of sections K in a mesh shape and calculating the yield (average yield, etc.) of each section K. FIG. 8 schematically shows a state in which the work area A1 is divided into a plurality of sections K. For example, each section K is a square area of 5 m × 5 m in terms of actual size in the corresponding field F1. However, the shape and size of each section K are not particularly limited. In FIG. 8, the coordinate information (section number) of the X coordinate (X axis) and the Y coordinate (Y axis) is attached as the identification information of each section K.

Specifically, the map generation unit 216 generates map information including information such as the corresponding "section number" and "work data" for each section K of the work area A1. The section number is the identification information of the section K. As a result, the work data (for example, the yield per unit area) calculated by the data calculation processing unit 215 is registered for each section K. The information processing unit 21 acquires a plurality of work information D1 corresponding to a plurality of sampling positions in the section K for each section K, and calculates, for example, the yield per unit area (g / m ² ). Record as work data for map information. Each work data registered in the map information may be a representative value of the work information in each section K, and is not limited to an average value such as the yield per unit area, but the total value, the median value, and the median value in each section K. It may be a representative value such as a mode value, a maximum value, or a minimum value. As an example, when the work information D1 includes the harvest amount information as the actual information, the work data may be the total value (cumulative value) of the harvest amount in each section K.

Here, since the number of sampling positions included in one section K may differ depending on the section K, the work data is equally distributed among the plurality of sections K regardless of the number of sampling positions included in the section K. It is preferable to calculate. For example, when the work data is the total value (cumulative value) of the yields in each section K, if a plurality of work information D1s in the section K are simply accumulated, the work data becomes larger in the section K having a larger number of sampling positions. Therefore, inequality occurs among a plurality of compartments K. Therefore, the data calculation processing unit 215 normalizes the plurality of work information D1 corresponding to the section K by multiplying by a coefficient corresponding to the number of sampling positions, or works information for the section K having a small number of sampling positions. It is preferable to interpolate D1. Similarly, when the yield per unit area is used as the work data, the data calculation processing unit 215 calculates the cumulative yield normalized or interpolated for each section K, and then calculates the cumulative yield in the area of the section K. It is preferable to calculate the work data by dividing.

In this way, the map generation unit 216 creates the map M1 based on the work data of each section K calculated by the data calculation processing unit 215 as shown in FIG. FIG. 9 shows an example of the map M1. Based on the work data calculated by the data calculation processing unit 215, the map generation unit 216 maps the map M1 by, for example, associating a multi-gradation gray shade (gray scale) with the value of the work data. create. In the example shown in FIG. 9, for each section K, the lighter the color, the smaller the yield, and the darker the color, the higher the yield. This makes it possible to create a map M1 showing the distribution of the yield corresponding to the entire field F1. Further, the number of sections K (number of divisions) in the field F1 can be increased to create a high-definition map M1. The map generation unit 216 may or may not display the "numerical value" of the work data in each section K of the map M1.

[5.3] Section Setting Process Next, a "section setting process" for setting a plurality of sections K in the work area A1 will be described. The above-mentioned map M1 is generated by using a plurality of partitions K set by the process as described below. In the present embodiment, as the mode of the section setting unit 214, a first mode in which a plurality of sections K including a large section Kl and a small section Ks are set, and a plurality of sections including only one of the large section Kl and the small section Ks are included. There are two types of modes, a second mode for setting the partition K and a second mode for setting the partition K. Then, the section setting unit 214 can switch between the first mode and the second mode according to the operation of the user accepted by the operation reception unit 23. That is, in the present embodiment, there are two types of setting methods for setting the section K. Therefore, in the following, the setting process of the section K by the section setting unit 214 will be described separately for the first mode and the second mode.

[5.3.1] Setting of a section in which a large section and a small section are mixed First, when the mode of the section setting unit 214 is in the first mode, that is, a plurality of sections K in which the large section Kl and the small section Ks are mixed are selected. The setting process of the section K in the case of setting will be described.

In the first mode, the section setting unit 214 sets at least two types of sections K having different sizes, instead of a uniform section K, as shown in FIG. 10, for example. In the example of FIG. 10, the plurality of compartments K include a plurality of large compartments Kl (indicated by a dotted line in FIG. 10) and a plurality of small compartments Ks (indicated by a solid line in FIG. 10). In the present embodiment, as an example, the large compartment Kl and the small compartment Ks are both square regions, and the small compartment Ks is each region when the large compartment Kl is further divided into nine. Therefore, in terms of the length of one side, the large compartment Kl has three times the length of the small compartment Ks. In this way, the section setting unit 214 changes the roughness of the mesh in the work area A1 to show the distribution of work data more finely on the map M1 for a specific range in the work area A1. Is possible.

In the present embodiment, as illustrated in FIG. 10, when the work area A1 is divided into the outer peripheral side range A101 and the central side range A102 of the work area A1, the outer peripheral side range A101 The small section Ks is set in, and the large section Kl is set in the range A102 on the center side. As an example, assuming a boundary line L1 that is a constant distance from the outer periphery of the work area A1, a small section Ks is set in the range A101 outside the boundary line L1 (outer peripheral side), and the inside of the boundary line L1 ( A large section Kl is set in the range A102 (on the side opposite to the outer circumference). As a result, the particle size of the mesh (section K) is set finer for the outer peripheral portion of the work area A1, that is, the range A101 at a certain distance from the outer circumference, as compared with the other ranges A102, and the work data is finer on the map M1. Can show the distribution of.

In this way, in the vicinity of the center of the field F1 where work by the work machine is easy to perform, a mesh with a coarse grain size can be set like a large section Kl, and conversely, in the vicinity of the outer periphery of the field F1 where fine work is difficult to perform, a small section can be set. A mesh with a fine grain size such as Ks can be set. Therefore, it becomes easy to analyze in detail whether or not the work is accurately executed in the vicinity of the outer periphery of the field F1 on the map M1. Further, in the present embodiment, the small compartment Ks is a region after each division when the large compartment Kl is divided into two or more (9 divisions in the example of FIG. 10). Therefore, a plurality of small sections Ks can be set in the same coordinate system as the large section Kl, and it is relatively easy to set the small sections Ks.

By the way, when a plurality of sections K in which a large section Kl and a small section Ks coexist are set, the work by the work machine includes the tilling work, and the plurality of work information D1 provides information on the tilling depth (cultivation depth). It is preferable to include it. That is, according to the above configuration, the work data in the vicinity of the outer periphery of the field F1 can be analyzed in detail, so that the work status is analyzed to every corner of the field F1 even for the work that should be performed on the entire area of the field F1 such as the tilling work. It will be easier to do.

Similarly, when a plurality of compartments K in which a large compartment Kl and a small compartment Ks coexist are set, it is preferable that the work by the work machine includes the fertilizer application work and the plurality of work information includes information on the fertilizer application amount. That is, according to the above configuration, the work data in the vicinity of the outer periphery of the field F1 can be analyzed in detail, so that the work status is analyzed to every corner of the field F1 even for the work that should be performed on the entire area of the field F1 such as fertilization work. It will be easier to do.

Further, in the present embodiment, the section setting unit 214 specifies a range in which the large section Kl or the small section Ks is set in the work area A1 according to the operation of the user, so that any part of the work area A1 can be set. Subsection Ks can be set. For example, in the field F1, the user can specify a range in which a small section Ks is set as a range in which a finer distribution of work data is desired, such as a range in which an obstacle such as a sprinkler exists. The position of the boundary line L1 described above, that is, the distance from the outer circumference to the boundary line L1 may be specified according to the user's operation.

FIG. 11 shows an example of a procedure for setting a plurality of compartments K in which a large compartment Kl and a small compartment Ks are mixed, as illustrated in FIG. That is, as shown on the left side of FIG. 11, the section setting unit 214 first sets a coarse-grained mesh composed of a plurality of large sections Kl covering the entire area of the work area A1. Next, as shown on the right side of FIG. 11, the section setting unit 214 sets the boundary line L1 at a constant distance from the outer periphery of the work area A1 and covers the range A101 outside the boundary line L1 in the work area A1. A fine-grained mesh consisting of a plurality of subsections Ks is set. Then, the section setting unit 214 sets a plurality of sections K as shown in FIG. 10 by superimposing a fine mesh composed of a plurality of small sections Ks on a coarse mesh composed of a plurality of large sections Kl.

Further, in FIGS. 10 and 11, for example, a straight line extending in the east-west direction is defined as the X-axis, a straight line extending in the north-south direction is defined as the Y-axis, and the X-axis and the Y-axis are defined regardless of the orientation of the work area A1. Along the way, a case where a plurality of sections K are set in the work area A1 will be illustrated. However, the present invention is not limited to this, and as shown in FIGS. 8 and 9, for example, the X-axis and the Y-axis along each side of the work area A1 are defined, and the work area A1 is defined along the X-axis and the Y-axis. May be set in a plurality of compartments K.

[5.3.2] Setting uniform compartments Next, when the mode of the compartment setting unit 214 is in the second mode, that is, a plurality of uniform compartments K including only one of the large compartment Kl and the small compartment Ks. The setting process of the section K in the case of setting will be described.

In the second mode, the section setting unit 214 has a plurality of sections K that are common to the reference area As1 including the overlapping area Ax1 that overlaps with each other for the area group A100 having a plurality of work areas A1 set by the area setting unit 213. Is set for each work area A1. The "region group" referred to in the present disclosure is, for example, a set of a plurality of work regions A1 set corresponding to the same field F1. That is, since various operations are performed even in the same field F1, such as tilling, planting (rice planting), fertilization, and harvesting, a work area A1 may be set for each of these operations. Alternatively, for the same field F1, for example, the work area A1 may be set every year. In these cases, each time the work area A1 is set, a plurality of work areas A1 having different positions and shapes may be set even for the same field F1. In particular, as described in the “[5.11] Automatic setting of work area” column, when the work area A1 corresponding to the field F1 is automatically set based on the plurality of position information D2, The position and shape are likely to differ in the plurality of work areas A1.

Therefore, in the present embodiment, even when a plurality of work areas A1 having different positions and shapes are set, the section setting unit 214 may at least cover the overlapping areas Ax1 that overlap each other in the plurality of work areas A1. It has a function to set a plurality of common sections K. This makes it easier to compare the maps M1 with each other between different operations in the same field F1 or the same operations in different years.

Here, as shown in FIG. 12, it is assumed that four work areas A11 to A14 are set for the same field F1. In this case, the section setting unit 214 sets a plurality of sections K common to the reference area As1 including at least the overlapping area Ax1 for the area group A100 including the four work areas A11 to A14 for each work area A1. .. Specifically, as shown in FIG. 13, when the four working areas A11 to A14 included in the area group A100 are overlapped in the same coordinate system, the areas overlapping with each other become the overlapping area Ax1. Then, in the reference region As1 including the entire area of the overlapping region Ax1, a plurality of common compartments K are set by the compartment setting unit 214.

As an example in the present embodiment, the reference region As1 includes a union of a plurality of working regions A1 in the region group A100. That is, as shown in FIG. 13, the section setting unit 214 extracts the region that is the union of the four work regions A11 to A14 as the reference region As1. Such a reference region As1 is a region defined by a set of outer circumferences located at the outermost periphery of the plurality of working regions A11 to A14, and naturally includes an overlapping region Ax1. In other words, the four working areas A11 to A14 in the area group A100 are all included in the reference area As1 consisting of the union.

Then, as shown in FIG. 14, the section setting unit 214 sets a plurality of sections K common to the reference area As1 for each work area A1 for the area group A100. Specifically, the section setting unit 214 sets a plurality of sections K for the reference area As1, and makes the plurality of sections K available in the plurality of work areas A11 to A14. That is, although the plurality of sections K are set for each of the plurality of work areas A11 to A14, the plurality of sections K that are common to the reference area As1 including the overlapping area Ax1 of the plurality of work areas A11 to A14. Is set. Therefore, at least in the overlapping area Ax1, a common section K is used in the plurality of work areas A11 to A14. In particular, in the present embodiment, since the common section K is set in the reference region As1 composed of the union, the common section K is used in the entire area of the plurality of work areas A11 to A14.

According to the above configuration, even when a plurality of work areas A1 are set for the same field F1, in these plurality of work areas A1, at least the same position and shape (including size) with respect to the overlapping area Ax1. ) Section K is set. In other words, even when a plurality of work areas A1 having different positions and shapes are set, it is possible to align the positions and sizes of the meshes at least for the overlapping areas Ax1 that overlap each other in the plurality of work areas A1. Therefore, it becomes easy to compare the maps M1 with each other between different operations in the same field F1 or the same operations in different years.

By the way, it is preferable that the area group A100 includes two or more work areas A1 related to work with different work machines. As a result, even for work with different work machines, it becomes easy to compare information (work data) related to different work in the same section K after sharing the section K.

Further, the function of sharing the section K among the plurality of work areas A1 is to set a plurality of sections K in which the large section Kl and the small section Ks coexist when the mode of the section setting unit 214 is in the first mode. It is also available in some cases. In this case, the section setting unit 214 has a plurality of areas A100 including the four work areas A11 to A14 that are common to at least the reference area As1 including the overlapping area Ax1 and in which the large section Kl and the small section Ks coexist. Section K is set for each work area A1.

[5.4] Display processing Next, a "display processing" for displaying the generated map M1 and the like will be described. In the present embodiment, there are two modes of the display processing unit 217, a first display mode in which only one map M1 is displayed and a second display mode in which a plurality of maps M1 are displayed side by side. Then, the display processing unit 217 can switch between the first display mode and the second display mode according to the user's operation received by the operation reception unit 23. That is, in the present embodiment, there are two types of display modes of the map M1 by the display processing unit 217: a single display in which the map M1 is displayed independently and a contrast display in which a plurality of maps M1 are displayed side by side. .. Therefore, in the following, the display processing by the display processing unit 217 will be described separately for the first display mode and the second display mode. In FIGS. 15 and 17 showing the display screen Im1, the alternate long and short dash line, leader line, and reference numeral representing the area are attached only for explanation and are not actually displayed on the display unit.

[5.4.1] Independent Display First, a display process will be described when the mode of the display processing unit 217 is in the first display mode, that is, when only one map M1 is displayed in the display screen Im1.

In the first display mode, as illustrated in FIG. 15, the display processing unit 217 causes the display unit (operation display unit 33) of the user terminal 3 to display the display screen Im1 including only one map M1. .. The display screen Im1 in FIG. 15 includes a map image Im10, a first input field C1, a second input field C2, a third input field C3, and explanatory information C4.

The map image Im10 is an image showing a map including the field F1, and may be realized by aerial photography, computer graphics, or the like. In the present embodiment, the display processing unit 217 displays the map M1 in the work area A1 corresponding to the field F1 in the map image Im10. That is, the map M1 generated by the map generation unit 216 is displayed on the corresponding field F1 in the map image Im10 of the display screen Im1. As a result, on the display screen Im1, the work status in the field F1 is visualized as a map M1 representing work data (for example, the yield per unit area) for each of the plurality of sections K on the map. The map in the map image Im10 can be, for example, scrolled, enlarged / reduced, and page-switched according to the user's operation.

Further, in the present embodiment, the display processing unit 217 determines the map M1 to be displayed on the display screen Im1 according to the operation of the user who selects the work area A1 on the map image Im10 including the field F1. That is, when there is a work area A1 corresponding to a plurality of fields F1, which field F1 corresponds to the map M1 of the work area A1 is received by the operation reception unit 23 on the map image Im10. It is determined by the operation of the user who selects the work area A1. In the display screen Im1 illustrated in FIG. 15, the map image Im10 includes the first work area A11 corresponding to the first field F11 and the second work area A12 corresponding to the second field F12. Therefore, on the display screen Im1, the user selects the first work area A11 corresponding to the first field F11 on the map image Im10, so that the map M1 of the first work area A11 is displayed.

The first input field C1 is an input field for inputting the first item of the map M1 to be displayed on the display screen Im1. The first item is a year (or year) as an example, and the year (or year) of the data displayed as the map M1 is specified by the year (or year) input in the first input field C1. The second input field C2 is an input field for inputting the second item of the map M1 to be displayed on the display screen Im1. The second item is a work name as an example, and the work name of the data displayed as the map M1 is specified by the work name input in the second input field C2. The third input field C3 is an input field for inputting the third item of the map M1 to be displayed on the display screen Im1. The third item is attribute information for specifying work data as an example, and the work data displayed as the map M1 is specified by the work input to the third input field C3. That is, the first item and the second item are items for specifying the work to be mapped together with the selection of the work area A1, and the third item is for specifying the work data itself to be mapped. It is an item. In the example of FIG. 15, the input formats of the first input field C1, the second input field C2, and the third input field C3 are all selective input formats to be selected from the default values, but the input format is not limited to this. It may be in an input format.

The explanatory information C4 is information including the explanation of the work data in the map M1. Specifically, the explanatory information C4 is a legend showing how the multi-gradation gray shades (gray scale) in the map M1 are associated with the values of the work data. In the example of FIG. 15, the explanatory information C4 has a minimum value (lightest color) of 50.00 (kg / a) and a maximum value (darkest color) of the work data consisting of the yield per unit area. It shows that it is 110.00 (kg / a). That is, in the present embodiment, the display processing unit 217 displays the explanatory information C4 including the explanation of the work data on the display screen Im1. As a result, the user can easily understand the meaning of the map M1.

As described above, in the present embodiment, the display processing unit 217 determines the work area A1, the first item, the second item, and the third item to be mapped according to the operation of the user on the display screen Im1, and the map M1. Is displayed. Therefore, on the display screen Im1, for example, when the year (or year) selected in the first input field C1 is changed, the map M1 in the map image Im10 is changed in real time. When only the work area A1 is selected, it is preferable that the map M1 or the like of the latest (most recent) work is displayed according to the initial display condition as an example. Further, on the display screen Im1, in addition to or in place of the year (or year) and the work name, for example, the input of attribute information such as the work machine, the worker, and the crop to be used may be accepted.

Here, the map information for displaying the map M1 displayed on the display screen Im1 may be generated by the map generation unit 216 each time, or may be generated in advance. The map information generated in advance by the map generation unit 216 is included in, for example, the data table Ta1 as shown in FIG. 16 and stored in the data storage unit 22. The data table Ta1 includes, for example, columns for "work area", "work name", "start date and time", "end date and time", "latitude and longitude polygon", and "attribute information". The "attribute information" column includes items such as the yield per unit area as work data, and the map information generated by the map generation unit 216 is stored in the "attribute information" column. The data table Ta1 is a table in which data including map information is stored for each work, and in the example of FIG. 16, each row corresponds to an individual work.

According to such a data table Ta1, for example, when the work area A1 is selected and the first item (year or year) and the second item (work name) are specified, the map information regarding any work is specified. Can be called. That is, for example, it is possible to search the map information related to an arbitrary work on the data table Ta1 by using the work area A1, the year or year, and the work name as keys. Therefore, the display processing unit 217 calls the data from the data table Ta1 according to the work area A1, the first item, the second item, and the third item designated on the display screen Im1, and the map M1 is displayed on the display screen Im1. Can be displayed.

Further, on the display screen Im1 shown in FIG. 15, the work area A1 is divided into a plurality of sections K, and then the map M1 showing the work data for each section K is displayed, but the present invention is not limited to this example. That is, for example, regarding information such as the used work machine, average work speed, variation in work speed, and work time, even if one work data is displayed on the display screen Im1 for one work area A1. good. In this case, for example, the work data for the work area A1 may be displayed by "solid painting" in which the work area A1 in the map image Im10 is uniformly filled.

[5.4.2] Contrast display Next, a display process will be described when the mode of the display processing unit 217 is in the second display mode, that is, when a plurality of maps M1 are displayed side by side on the display screen Im1.

In the second display mode, as illustrated in FIG. 17, the display processing unit 217 displays the display screen Im1 including a plurality of (here, two) maps M1 on the display unit (operation display unit) of the user terminal 3, for example. It is displayed in 33). The display screen Im1 in FIG. 17 displays two screens similar to those in the case of single display side by side in the horizontal direction (horizontal direction). That is, this display screen Im1 is a screen including two sets of the map image Im10, the first input field C1, the second input field C2, the third input field C3, and the explanatory information C4. Therefore, the display processing unit 217 causes the map M1 to be displayed on each of the map image Im10 on the left side and the map image Im10 on the right side of the display screen Im1.

Here, the left half and the right half of the display screen Im1 can be individually displayed by calling the map M1 related to an arbitrary work, as in the case of the single display. That is, for example, regarding the selection of the work area A1 on the map image Im10, the user can select different work areas A1 on the left side and the right side of the display screen Im1. Further, for example, in each of the first input field C1, the second input field C2, and the third input field C3, the user can input different information on the left side and the right side of the display screen Im1. ..

Here, the display processing unit 217 may call the map information related to any work by using the data table Ta1 as illustrated in FIG. 16 as in the first display mode. As a result, it is possible to call and display an arbitrary map M1 side by side, for example, starting from the work area A1 without systematically creating a database of the work.

As a result, in the present embodiment, the display processing unit 217 displays a plurality of maps M1 including work data for items different from each other side by side on the display screen Im1. Therefore, by comparing a plurality of maps M1 for different items on the display screen Im1, the user can find the difference in the work due to the difference in the items, and for example, it becomes easy to find the improvement point regarding the work.

In particular, in the present embodiment, the display processing unit 217 displays the display screen Im1 including the plurality of maps M1 on a single display unit at the same time. Therefore, the user can compare a plurality of maps M1 on the display screen Im1 without switching screens, and has an advantage that it is easy to compare a plurality of maps M1. However, the "side-by-side display" referred to in the present disclosure is not only a mode in which the display is simultaneously displayed on a single display unit, but also a mode in which the display screen Im1 is displayed by an operation such as scrolling, enlargement / reduction, or page switching. Further, the mode displayed in a separate window is also included.

In the example of FIG. 17, on the left side of the display screen Im1, a map M1 showing the yield per unit area related to the harvesting work in “FY2019” for the first work area A11 is displayed. On the other hand, on the right side of the display screen Im1, a map M1 showing the yield per unit area related to the harvesting work in "FY2018" is displayed for the first work area A11.

That is, in the example of FIG. 17, the plurality of maps M1 displayed side by side on the display screen Im1 include common items for work data. This common term includes items relating to work area A1. That is, in the example of FIG. 17, the work area A1 is common in the plurality of maps M1, and the second item (work name) and the third item (work data) are also common. As described above, since there is a common term among a plurality of maps M1 displayed side by side, it becomes easy to find a difference in work due to a difference in items other than the common term. In particular, since the common item includes the item related to the work area A1, it becomes easy to find the difference in work from the comparison between the maps M1 for the same field F1.

On the other hand, in the example of FIG. 17, only the first item (year) is different in the plurality of maps M1. That is, the plurality of maps M1 displayed side by side on the display screen Im1 have different items (here, "year") related to the work time axis of the work machine. As a result, the user can compare the work across the years from the map M1 of the same or different work targets in different years.

Further, for example, not only the year (or year) but also each of the second input field C2 and the third input field C3, the user can input different information on the left side and the right side of the display screen Im1. Various maps M1 can be compared. As an example of a plurality of maps M1 to be compared, there is a map M1 of different work in the same year. For example, by displaying the map M1 of the fertilizer application work and the map M1 of the harvesting work side by side in the same year, it is possible to see the correlation between the fertilizer application amount and the harvest amount. As another example, by displaying the map M1 of the tillage depth and the map M1 of the growth state side by side in the same year, it is possible to see the correlation between the cultivation depth and the growth state.

Further, for example, a plurality of maps M1 displayed side by side on the display screen Im1 may include work data regarding yields of different crops. As a result, for the user, for example, it is possible to easily compare the yields when different crops are cultivated in the same field F1 depending on the year. As an example, it is possible to compare the yield of "rice" in FY2018 with the yield of "wheat" in FY2019. Alternatively, the plurality of maps M1 displayed side by side on the display screen Im1 may include work data regarding the yield of the same crop. Thereby, for the user, for example, in the same field F1, it is possible to easily compare the yields by year.

Further, in the plurality of maps M1 displayed side by side on the display screen Im1, the division K is shared among the plurality of work areas A1 as described in "[5.3.2] Setting of uniform division". It may or may not be standardized. If it is not standardized, for example, a plurality of sections K in which a large section Kl and a small section Ks are mixed may be set only for one map M1.

[5.5] Flow Chart FIG. 18 is a flowchart showing an example of the flow of the work management method described above. Each process shown in the flowchart is mainly executed by the information processing unit 21 of the management server 2. Here, a case where the operation mode of the area setting unit 213 is in the first operation mode, that is, a case where the area setting unit 213 automatically sets the work area A1 will be described. For example, a series of processes related to the work management method is started by the information processing unit 21 when the management server 2 acquires the work information D1 from the work machine (combine 4). Further, a series of processes related to the work management method may be started in response to a predetermined user operation on the management server 2.

First, in step S1, the information processing unit 21 determines whether or not the work information D1 including the position information D2 has been acquired from the combine 4 which is a work machine. When it is determined that the work information D1 in the work period has been acquired (S1: Yes), the process proceeds to step S2. The information processing unit 21 waits until the work information D1 is acquired (S1: No). When the information processing unit 21 (work acquisition unit 212) acquires the work information D1 from the combine 4, the information processing unit 21 stores the work information D1 in the work information storage unit 221 (see FIG. 5).

In step S2, the information processing unit 21 extracts the position information D2 from the work information D1. As a result, the information processing unit 21 (position acquisition unit 211) acquires the position information D2 during the working period.

Next, in step S3, the information processing unit 21 sets the work area A1 based on the acquired position information D2. That is, since the operation mode of the area setting unit 213 is in the first operation mode, the information processing unit 21 (area setting unit 213) automatically sets the work area A1 based on the plurality of position information D2. The information processing unit 21 (area setting unit 213) stores the information regarding the set work area A1 in the work area storage unit 222 and registers the work area A1.

Next, in step S4, the information processing unit 21 determines whether or not the display instruction of the map M1 has been acquired from the user. When the information processing unit 21 acquires the display instruction of the map M1 from the user (S4: Yes), the process proceeds to step S5. The information processing unit 21 waits until the display instruction of the map M1 is acquired from the user (S4: No).

In step S5, the information processing unit 21 determines whether or not the mode of the partition setting unit 214 is the first mode. When the mode of the partition setting unit 214 is the first mode (S5: Yes), the process proceeds to step S6. On the other hand, when the mode of the partition setting unit 214 is the second mode (S5: No), the process proceeds to step S7.

In step S6, the information processing unit 21 (section setting unit 214) sets a plurality of sections K in which the large section Kl and the small section Ks coexist. At this time, according to the operation of the user, a range in which the large section Kl or the small section Ks is set in the work area A1 is specified.

In step S7, the information processing unit 21 (section setting unit 214) sets a uniform plurality of sections K including only one of the large section Kl and the small section Ks. At this time, if a plurality of work areas A1 having different positions and shapes are set for the same field F1, the section setting unit 214 may at least cover the overlapping areas Ax1 that overlap each other in the plurality of work areas A1. A plurality of common sections K are set.

Next, in step S8, the information processing unit 21 (data calculation processing unit 215) determines the yield corresponding to a plurality of sampling positions in the section K for each section K based on the work information D1 acquired in step S1. Obtain it and calculate, for example, the yield per unit area (g / m ² ). The information processing unit 21 registers the calculated work data (harvest amount) as map information. As a result, the yield of the entire field F1 is calculated.

Next, in step S9, the information processing unit 21 (map generation unit 216) creates a map M1 corresponding to a plurality of sections K in the field F1 based on the calculated work data (harvest amount).

On the other hand, when the mode of the display processing unit 217 is the second display mode (S10: No), the processing proceeds to step S12.

In step S11, the information processing unit 21 (display processing unit 217) causes the display unit (operation display unit 33) of the user terminal 3 to display the display screen Im1 including only one map M1. At this time, the map M1 to be displayed on the display screen Im1 is determined according to the operation of the user who selects the work area A1 on the map image Im10. Further, the information processing unit 21 (display processing unit 217) accepts inputs of the first item, the second item, and the third item on the display screen Im1.

In step S12, the information processing unit 21 (display processing unit 217) causes the display unit (operation display unit 33) of the user terminal 3 to display the display screen Im1 including the plurality of maps M1 arranged side by side. At this time, the plurality of maps M1 to be displayed on the display screen Im1 are determined according to the operation of the user who selects the work area A1 on the map image Im10. Further, the information processing unit 21 (display processing unit 217) accepts inputs of the first item, the second item, and the third item for each of the plurality of maps M1 on the display screen Im1.

In step S13, the information processing unit 21 determines whether or not the end instruction has been received from the user. When the user performs an operation to end the use of the work support site on the user terminal 3, the information processing unit 21 receives the end instruction (S13: Yes) and ends a series of processes related to the work management method. When the information processing unit 21 does not accept the end instruction (S13: No), the process proceeds to step S4 and the above process is repeated.

As described above, the information processing unit 21 executes a series of processes related to the work management method. However, the flowchart shown in FIG. 18 is merely an example, and the processes may be added or omitted as appropriate, or the order of the processes may be changed as appropriate.
