[0009] Hereinafter, an embodiment of the agricultural work management system disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiment described below.

[0010] <Outline of the farm work management system> An overview of a farm work management system 1 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram illustrating the overview of a farm work management system 1 according to an embodiment.

[0011] 1, the agricultural work management system 1 includes a combine harvester 10, a transport vehicle 20, a dryer 31, a rice huller 32, a sorter 33, and a control device 40. The combine harvester 10 harvests stalks of rice (paddy) or wheat while traveling within a farm field F, and threshes grains (such as rice grains) from the harvested stalks.

[0012] The combine harvester 10 includes a positioning device 11 (see FIGS. 2 and 3). The positioning device 11 determines the position P of the combine harvester 10. The positioning device 11 is, for example, a Global Navigation Satellite System (GNSS) device. The GNSS device can receive radio waves from navigation satellites orbiting the Earth to determine the position P of the combine harvester 10 and can also measure time.

[0013] For this reason, the combine 10 can be operated manually by an operator (worker) on board to perform work in the field F, or it can be automatically operated by a control unit 411 (see Figure 4), which will be described later, using position information from the positioning device 11, for example, to perform work in the field F.

[0014] The transport vehicle 20 is, for example, a truck. A container 21 for storing grains is loaded on the bed of the transport vehicle 20 such as a truck. The transport vehicle 20 stores grains discharged from the combine harvester 10 in the container 21. When the container 21 becomes full of grains, for example, the transport vehicle 20 transports the grains to a drying facility 30.

[0015] The dryer 31 is installed in a drying facility 30. The drying facility 30 is located away from the field F where the combine 10 works. The dryer 31 dries grains transported by the transport vehicle 20. A plurality of dryers 31 (for example, five dryers A to E) are installed. In this embodiment, of the five dryers 31 A to E shown in FIG. 1, three dryers 31 A to C are set for good crops, which will be described later, and two dryers 31 D and E are set for poor crops, which will be described later.

[0016] The rice huller 32 is installed within the drying facility 30. The rice huller 32 removes husks (such as rice husks) from the grains dried by the dryer 31. The sorter 33 is installed within the drying facility 30. The sorter 33 measures the weight of the grains (such as brown rice) from which the husks have been removed by the rice huller 32. The sorter 33 also sorts out grains that do not meet predetermined conditions (such as broken rice) from among the grains.

[0017] The control device 40 is a computer equipped with a processing device such as a CPU (Central Processing Unit), a storage device such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a HDD (Hard Disk Drive), and further an input / output device.

[0018] The control device 40 is mounted on a tablet terminal 41 that is detachably attached to the combine harvester 10. The tablet terminal 41 is capable of communicating with the combine harvester 10 via a short-range wireless communication standard such as Bluetooth (registered trademark). The tablet terminal 41 (control device 40) also functions as a control unit 411 (see FIG. 4) of the combine harvester 10. The tablet terminal 41 stores various information such as the working time, travel distance, and fuel consumption of the combine harvester 10, and displays the various information on a display screen.

[0019] The control device 40 is mounted on a tablet terminal 42 that is detachably provided to the dryer 31. The tablet terminal 42 is capable of communicating with the dryer 31 by a short-range wireless communication standard such as Bluetooth (registered trademark). The tablet terminal 42 (control device 40) functions as a control unit 421 (see FIG. 5) of the dryer 31. The tablet terminal 42 stores various information such as the operation / stop status of the dryer 31, the available input amount, and the drying time, and displays the various information on a display screen.

[0020] The control device 40 is mounted on a tablet terminal 43 that is detachably provided on the rice huller 32. The tablet terminal 43 is capable of communicating with the rice huller 32 by a short-range wireless communication standard such as Bluetooth (registered trademark). The tablet terminal 43 (control device 40) functions as a control unit 431 (see FIG. 6) of the rice huller 32. The tablet terminal 43 stores various information such as the operation / stop status of the rice huller 32, the amount of rice that can be put in, and the hulling time, and displays the various information on a display screen.

[0021] The control device 40 is mounted on a tablet terminal 44 that is detachably attached to the sorting machine 33. The tablet terminal 44 is capable of communicating with the sorting machine 33 by a short-range wireless communication standard such as Bluetooth (registered trademark). The tablet terminal 44 (control device 40) functions as a control unit 441 (see FIG. 7) of the sorting machine 33. The tablet terminal 44 stores various information such as the weighing results of the sorting machine 33, and displays the various information on a display screen.

[0022] In the above configuration example, the control device 40 is installed in each of the multiple tablet terminals 41 to 44, but may also be consolidated into a single tablet terminal, such as the tablet terminal 41 on the side of the combine 10 that can be carried by the worker during harvesting work.

[0023] The control device 40, the combine harvester 10, the transport vehicle 20, the dryer 31, the rice huller 32, and the sorter 33 are communicatively connected via a communication network such as the Internet. The control device 40 may also be mounted on an information processing device used as a server device 51, which will be described later.

[0024] The farm work management system 1 includes a server device 51. The server device 51 is installed, for example, in a management building 50 that manages agricultural machinery such as the combine harvester 10 and the field F. The server device 51 is communicably connected to the combine harvester 10, the transport vehicle 20, the dryer 31, the rice huller 32, the sorter 33, and the tablet terminals 41 to 44 via a communication network such as the Internet.

[0025] The agricultural work management system 1 also includes a display unit. The display unit displays various information related to agricultural work. Examples of the display unit include the display screens of the tablet terminals 41-44 and the display screen of a monitor device connected to an information processing device used as the server device 51.

[0026] In the farm work management system 1, it is possible to select the most suitable dryer 31 from multiple (five) dryers 31 depending on the quality of the grains transported from the farm field F.

[0027] When selecting such a dryer 31, the control device 40 acquires map information (hereinafter, referred to as a field map) corresponding to the field F. The control device 40 acquires the position P of the combine harvester 10, and registers the position information in the field map based on the position P of the combine harvester 10.

[0028] The control device 40 acquires information such as the harvest load of the crop (rice) from the combine harvester 10. That is, the control device 40 detects a position where the harvest load of the combine harvester 10 is high (for example, an area A where a poor crop is growing, such as a crop that has fallen over). L ) is acquired. The control device 40 registers information about the crops in the field F, including each piece of information acquired from the combine harvester 10, in position information within the field map. In other words, the positions where the harvesting load of the combine harvester 10 became high are registered as part of the position information within the field map.

[0029] The control device 40 distinguishes the grains threshed from the harvested stalks at the position where the harvesting load of the combine harvester 10 is high from other grains by, for example, storing the transport vehicle 20 that transports the grains. The control device 40 selects, from among the multiple (five) dryers 31, a dryer 31 that will give priority to drying the grains at the position where the harvesting load of the combine harvester 10 is high.

[0030] <Combine> The combine harvester 10 will be described with reference to Figures 2 to 4. Figure 2 is a schematic side (left side) view showing the combine harvester 10.

[0032] In the following description, the combine 10 may be referred to as the "machine."

[0033] As shown in Figures 2 and 3, the combine 10 is equipped with a pair of left and right crawlers 13 that are mounted on the lower part of the body frame 12 of the combine 10 and serve as traveling devices that travel on the soil surface of the field F (see Figure 1), a harvesting device 14 that is mounted on the front of the body frame 12 and harvests the stalks in the field F, and a threshing device 15 that is mounted on the left side behind the harvesting device 14 and threshes the stalks harvested by the harvesting device 14 and sorts the threshed grains.

[0034] The combine harvester 10 also includes a control unit 16 on which an operator (worker) sits, which is provided on the right side behind the harvesting device 14, and an engine room (not shown) which is provided below the control unit 16 and in which an engine (not shown) is mounted. The combine harvester 10 also includes a grain tank 17 provided behind the control unit 16 for storing grains threshed / sorted by the threshing device 15, and a discharge auger 18 connected to the grain tank 17 for discharging the grains stored in the grain tank 17 to the outside of the machine body.

[0036] The start switch 101 starts the engine. The speed sensor 102 measures the running speed of a pair of left and right crawlers 13 (see FIG. 2) which are the traveling device. The mode switch 103 switches the running speed of the crawlers 13 and the reaping and conveying speed of the reaping device 14 (see FIGS. 2 and 3) depending on the state of the stalks in the field F (see FIG. 1).

[0037] The weight sensor 104 measures the weight of the grains stored in the grain tank 17 (see Figures 2 and 3). The moisture sensor 105 measures the moisture percentage of the grains stored in the grain tank 17. The fuel sensor 106 measures the remaining amount of fuel (diesel) stored in a fuel tank (not shown). The receiving unit 4117 is provided in the positioning device 11 (see Figures 2 and 3) and receives position information transmitted from the GNSS.

[0038] The control unit 411 is connected on the output side to the transmission 108, monitor 109, communication unit 110, etc. via an output interface circuit. The transmission 108 increases or decreases the rotation speed of the engine. The monitor 109 displays the running speed of the pair of left and right crawlers 13, which are the traveling device. The communication unit 110 transmits data stored in the control unit 411.

[0039] <Dryer> The dryer 31 will be described with reference to Fig. 5 etc. Fig. 5 is a block diagram showing a control system of the dryer 31.

[0040] The dryer 31 includes an input section (not shown) and a burner (not shown). The input section is provided at the bottom of the dryer 31. The input section is an input port where grains transported by the transport vehicle 20 (see FIG. 1) are input (laid in). The burner is provided above the input port. The burner heats air from a fan (not shown) that blows toward the input grains.

[0041] In the dryer 31, grains fed into the feed section are exposed to hot air (air heated by a burner) while circulating inside the dryer 31, thereby removing a predetermined amount of moisture. In this case, the grains are transported to the upper part of the dryer 31 by an elevator (not shown) provided on the side wall of the dryer 31, and then drop toward the lower part of the dryer 31, where they are exposed to hot air again while the process of removing moisture is repeated, and the grains are dried.

[0042] This removes moisture from the grains, suppresses the grains from becoming steamed, and prevents deterioration of the grains' quality. The grains dried in the dryer 31 are transported to the rice huller 32 (see FIG. 1) via a connecting pipe (not shown).

[0043] 5, the dryer 31 includes a control unit 421. The input side of the control unit 421 is connected to the moisture meter 311 and the like via an input interface circuit. The moisture meter 311 measures the moisture content of the grains circulating inside the dryer 31.

[0046] <Rice huller> The rice huller 32 will be described with reference to Fig. 6 etc. Fig. 6 is a block diagram showing a control system of the rice huller 32.

[0047] The rice huller 32 comprises an input section (not shown) and a dehusking roll (not shown). The input section is provided at the upper front part of the rice huller 32. The input section is an input port through which grains dried in the dryer 31 (see FIG. 1) are input. The dehusking roll is provided in a pair. The dehusking roll removes husks from the grains.

[0048] In the rice huller 32, the grains fed into the input section are transported from above to below through the gap formed between a pair of husking rolls, and the husks are removed by the difference in peripheral speed between the pair of husking rolls with different diameters. The kernels (such as brown rice) from which the husks have been removed in the rice huller 32 are transported to the sorter 33 (see FIG. 1) via a connecting pipe (not shown).

[0049] 6, the rice huller 32 includes a control unit 431. The input side of the control unit 431 is connected to the moisture meter 321 and the like via an input interface circuit. The moisture meter 321 measures the moisture content of the grains circulating inside the rice huller 32.

[0050] The control unit 431 has an output side connected to the driving unit 322, the driving unit 323, the monitor 324, the communication unit 325, etc. via an output interface. The driving unit 322 rotates the pair of husking rolls. The driving unit 323 adjusts the gap between the pair of husking rolls. The monitor 324 displays the driving time of the pair of husking rolls, etc. The communication unit 325 transmits data stored in the control unit 431.

[0051] <Sorting machine> The huller 32 will be described with reference to Fig. 7 etc. Fig. 7 is a block diagram showing a control system of the sorter 33.

[0052] The sorting machine 33 includes a hopper (not shown) and a weighing scale 332 (see FIG. 7). The hopper is provided below the sorting machine 33. The hopper is an input port through which rice grains (such as brown rice) from which husks have been removed by the rice huller 32 are input. The weighing scale 332 is provided below the hopper. The weighing scale 332 measures the weight of the rice grains such as brown rice.

[0053] As shown in Fig. 7, sorter 33 includes a control unit 441. The input side of control unit 441 is connected to moisture meter 331, weighing scale 332, and the like via an input interface circuit. Moisture meter 331 measures the moisture content of grains such as brown rice fed into sorter 33. The weighing scale measures the weight of grains such as brown rice.

[0054] The control unit 441 has an output side connected to the driving device 333, the driving device 334, the monitor 335, the communication unit 336, and the like via an output interface.

[0055] <Selecting a dryer> Selection of the dryer 31 by the control device 40 will be described with reference to Figs. 8 to 10. Fig. 8 is a flowchart showing an example of a processing procedure for selecting the dryer 31. Fig. 9 is a flowchart showing another example of a processing procedure for selecting the dryer 31. Fig. 10 is a diagram showing a specific example of the selection of the dryer 31.

[0056] Conditions under which the harvesting load of the combine harvester 10 becomes high include crops falling over and the soil surface of the field F becoming muddy, but such conditions are not conducive to growing crops of good quality. For this reason, the position where the harvesting load of the combine harvester 10 becomes high, that is, the area where the crop is falling over and where it is assumed that a poor crop is growing (poor crop area) A L Even if low-quality grains such as those in the above-mentioned crops, i.e., defective crops, are separated and dried separately from other grains, if there is no available space in the dryer 31 (see FIG. 1), waiting time for drying will occur, and the quality of the grains may further deteriorate during the waiting time. In addition, the waiting time for drying may reduce work efficiency.

[0057] For this reason, in this embodiment, the control device 40 selects a dryer 31 from multiple dryers 31 (for example, five dryers 31 A to B shown in Figure 1) that is capable of starting drying of low-quality grains (defective crops) at the optimal timing.

[0058] The information used by the control device 40 to select the dryer 31 includes the area of ​​the field F to be harvested by the combine harvester 10, the harvesting speed of the combine harvester 10, the harvesting procedure, the distance from the field F to the drying facility 30 (dryer 31), the drying time of the grains by the dryer 31, the weight of the grains, etc. Of this information, the area of ​​the field F to be harvested by the combine harvester 10, the distance from the field F to the drying facility 30 (dryer 31), the drying time of the grains by the dryer 31, the weight of the grains, etc. are basically input automatically, while the harvesting speed of the combine harvester 10, the harvesting procedure, etc. are basically input manually by the operator.

[0059] In the example shown in FIG. 8, the control device 40 determines, from the crop harvesting load information acquired from the combine harvester 10, a position where the harvesting load of the combine harvester 10 is equal to or greater than a predetermined value, i.e., a defective crop area A L It is determined whether or not (step S101).

[0060] In the process of step S101, when the control device 40 determines that the position is one where the harvesting load of the combine harvester 10 is equal to or greater than a predetermined value (step S101: Yes), it determines that the harvested crop at this position is a defective crop (step S102). L The server device 51 then checks, based on past position information for the same field held by the server device 51, whether the previously registered position is one where the mowing load is equal to or greater than a predetermined value (step S103).

[0061] The control device 40 acquires the reaping performance per unit time of the combine harvester 10 and the remaining capacity of the grain tank 17 from the combine harvester 10 (step S104). The control device 40 calculates the time until the next grain discharge from the grain tank 17 based on the reaping performance of the combine harvester 10 and the remaining capacity of the grain tank 17, and further calculates the discharge time from the grain tank 17 from the time until the next grain discharge (step S105).

[0062] In addition, the control device 40 calculates the transport time of the grains from the combine 10 to the drying facility 30 based on the position information within the field map and the position of the drying facility 30 in which the dryer 31 is installed, calculates the time of grain discharge to the transport vehicle 20 based on the machine performance and harvesting volume of the combine 10, and further calculates the transport time from the field F based on the transport time to the drying facility 30 and the time of grain discharge to the transport vehicle 20 (step S106).

[0063] Control device 40 transmits the calculated value from tablet terminal 42 on the dryer 31 side to server device 51 (step S107).

[0064] On the server device 51 side, the control device 40 mounted on the server device 51 calculates the operating status of the dryers 31 for defective crops (for example, the dryers 31 D and E shown in FIG. 1), calculates the drying end / discharge end times of the dryers 31 for defective crops, checks other farm field information, and so on (step S108). Note that in the dryers 31 for defective crops, for example, the grain drying time is set longer than usual, and the airflow volume is set to a different amount than usual.

[0065] The control device 40 determines whether or not there is an available dryer 31 for defective crops (step S109). In the process of step S109, if the control device 40 determines that there is an available dryer 31 for defective crops (step S109: Yes), it calculates an estimated time from the end of drying of grains by the dryer 31 for defective crops to the completion of discharge, calculates the order in which the multiple dryers 31 for defective crops will become available, and further performs an order comparison of the available dryers 31 (step S110).

[0066] The control device 40 transmits the number of the available dryer 31 to, for example, the tablet terminal 42 on the available dryer 31 side (step S111).

[0067] Furthermore, in the processing of step S109, if the control device 40 determines that there is no available dryer 31 for defective crops (step S109: No), it calculates the waiting time (step S112) and transmits the waiting time and the number of the dryer 31 for defective crops to, for example, a tablet terminal 42 on the side of the available dryer 31 (step S113).

[0068] Furthermore, in the process of step S101, if the control device 40 determines that the harvesting load of the combine 10 is not equal to or greater than a predetermined value (i.e., less than a predetermined value) (step S101: No), it determines that the harvested crop at this position is a standard or above-standard crop, i.e., a good crop (step S114). Note that a standard crop is, for example, a crop (grain) with a moisture content of 35 percent or less in the case of unhulled rice, and a crop (grain) with a moisture content of 40 percent or less in the case of wheat. Grains with a moisture content higher than these values ​​are either submerged or immature.

[0069] When the control device 40 determines that the crop is of good quality, it registers the location information as an area in the field map where a good crop is assumed to be growing (good crop area), and checks from past location information of the same field held by the server device 51 whether the previously registered location was one where the mowing load was less than a predetermined value (step S115).

[0070] The control device 40 acquires the reaping performance per unit time of the combine harvester 10 and the remaining capacity of the grain tank 17 from the combine harvester 10 (step S116). The control device 40 calculates the time until the next grain discharge from the grain tank 17 based on the reaping performance of the combine harvester 10 and the remaining capacity of the grain tank 17, and further calculates the discharge time from the grain tank 17 from the time until the next grain discharge (step S117).

[0071] In addition, the control device 40 calculates the transport time of the grains from the combine 10 to the drying facility 30 based on the position information within the field map and the position of the drying facility 30 in which the dryer 31 is installed, calculates the grain discharge time to the transport vehicle 20 based on the combine 10's machine performance and harvesting volume, and further calculates the transport time from the field F based on the transport time to the drying facility 30 and the grain discharge time to the transport vehicle 20 (step S118).

[0072] Control device 40 transmits the calculated value from tablet terminal 42 on the dryer 31 side to server device 51 (step S119).

[0073] On the server device 51 side, the control device 40 mounted on the server device 51 calculates the operating status of the dryers 31 for good crops (for example, dryers 31 A to C shown in Figure 1), calculates the drying end / discharge end times of the dryers 31 for good crops, and checks other field information (step S120).

[0074] The control device 40 determines whether or not there is an available dryer 31 for good crops (step S121). In the process of step S121, if the control device 40 determines that there is an available dryer 31 for good crops (step S121: Yes), it calculates an estimated time from the end of drying of grains by the dryer 31 for good crops to the completion of discharge, calculates the order in which the multiple dryers 31 for good crops will become available, and further performs an order comparison of the available dryers 31 (step S122).

[0075] The control device 40 transmits the number of the available dryer 31 to, for example, the tablet terminal 42 on the available dryer 31 side (step S123).

[0076] Furthermore, in the processing of step S121, if the control device 40 determines that there is no available dryer 31 for good crops (step S121: No), it calculates the waiting time (step S124) and transmits the waiting time and the number of the dryer 31 for good crops to, for example, a tablet terminal 42 on the side of the available dryer 31 (step S125).

[0077] In this way, the control device 40 selects the dryer 31 to give priority to drying the grains that will be defective crops based on the time the grains are discharged from the combine 10, the remaining time for the grains from the combine 10, the estimated time from the end of grain drying to the completion of discharge, and the order in which the multiple dryers 31 for defective crops become available.

[0078] In the example shown in FIG. 9, the control device 40 determines, from the crop harvesting load information acquired from the combine harvester 10, a position where the harvesting load of the combine harvester 10 is equal to or greater than a predetermined value, i.e., a defective crop area A LIt is determined whether or not (step S201).

[0079] In the process of step S201, when the control device 40 determines that the position is one where the harvesting load of the combine harvester 10 is equal to or greater than a predetermined value (step S201: Yes), it determines that the harvested crop at this position is a defective crop (step S202). When the control device 40 determines that the crop is a defective crop, it displays a defective crop area A in the farm field map. L The server device 51 then checks, based on past position information for the same field held by the server device 51, whether the previously registered position is one where the mowing load is equal to or greater than a predetermined value (step S103).

[0080] The control device 40 acquires the reaping performance per unit time of the combine harvester 10 and the remaining capacity of the grain tank 17 from the combine harvester 10 (step S204). The control device 40 calculates the time until the next grain discharge from the grain tank 17 based on the reaping performance of the combine harvester 10 and the remaining capacity of the grain tank 17, and further calculates the discharge time from the grain tank 17 from the time until the next grain discharge (step S205).

[0081] In addition, the control device 40 calculates the transport time of the grains from the combine 10 to the drying facility 30 based on the position information within the field map and the position of the drying facility 30 in which the dryer 31 is installed, calculates the discharge time of the grains to the transport vehicle 20 based on the machine performance and harvesting volume of the combine 10, and further calculates the transport time from the field F based on the transport time to the drying facility 30 and the discharge time of the grains to the transport vehicle 20 (step S206).

[0082] Control device 40 transmits the calculated value from tablet terminal 42 on the dryer 31 side to server device 51 (step S207).

[0083] On the server device 51 side, the control device 40 mounted on the server device 51 calculates the operating status of the dryers 31 for defective crops (for example, the dryers 31 D and E shown in FIG. 1), calculates the drying end / discharge end times of the dryers 31 for defective crops, and checks other field information (step S208).

[0084] The control device 40 determines whether or not there is an available dryer 31 for defective crops (step S209). In the process of step S209, if the control device 40 determines that there is an available dryer 31 for defective crops (step S209: Yes), it calculates an estimated time from the end of drying of grains by the dryer 31 for defective crops to the completion of discharge, calculates the order in which the multiple dryers 31 for defective crops will become available, and further performs a sequence comparison of the available dryers 31 (step S210).

[0085] The control device 40 transmits the number of the available dryer 31 to, for example, the tablet terminal 42 on the available dryer 31 side (step S211).

[0086] Furthermore, in the processing of step S209, if the control device 40 determines that there is no available dryer 31 for defective crops (step S209: No), it determines whether or not to permit use of the dryer 31 for good crops (for example, dryers 31 A to C shown in FIG. 1) (step S212).

[0087] In the processing of step S201, if the control device 40 determines that the combine 10 is not at a position where the cutting load is greater than or equal to a predetermined value (i.e., less than a predetermined value) (step S201: No), it determines that the crop cut at this position is a standard or above-standard crop, i.e., a good crop (step S213).

[0088] When the control device 40 determines that the crop is of good quality, it registers the location information as an area in the field map where a good crop is assumed to be growing (good crop area), and checks from past location information of the same field held by the server device 51 whether the previously registered location was one where the mowing load was less than a predetermined value (step S214).

[0089] The control device 40 acquires the reaping performance per unit time of the combine harvester 10 and the remaining capacity of the grain tank 17 from the combine harvester 10 (step S215). The control device 40 calculates the time until the next grain discharge from the grain tank 17 based on the reaping performance of the combine harvester 10 and the remaining capacity of the grain tank 17, and further calculates the discharge time from the grain tank 17 from the time until the next grain discharge (step S216).

[0090] In addition, the control device 40 calculates the transport time of the grains from the combine 10 to the drying facility 30 based on the position information within the field map and the position of the drying facility 30 in which the dryer 31 is installed, calculates the time of grain discharge to the transport vehicle 20 based on the machine performance and harvesting volume of the combine 10, and further calculates the transport time from the field F based on the transport time to the drying facility 30 and the time of grain discharge to the transport vehicle 20 (step S217).

[0091] Control device 40 transmits the calculated value from tablet terminal 42 on the dryer 31 side to server device 51 (step S218).

[0092] On the server device 51 side, the control device 40 mounted on the server device 51 calculates the operating status of the dryers 31 for good crops (for example, dryers 31 A to C shown in Figure 1), calculates the drying end / discharge end times of the dryers 31 for good crops, and checks other field information (step S219).

[0093] The control device 40 determines whether or not there is an available dryer 31 for good crops (step S220). In the process of step S220, if the control device 40 determines that there is an available dryer 31 for good crops (step S220: Yes), it calculates an estimated time from the end of drying of grains by the dryer 31 for good crops to the completion of discharge, calculates the order in which the multiple dryers 31 for good crops will become available, and further performs a sequence comparison of the available dryers 31 (step S221).

[0094] The control device 40 transmits the number of the available dryer 31 to, for example, the tablet terminal 42 on the available dryer 31 side (step S222).

[0095] Furthermore, in the processing of step S220, if the control device 40 determines that there is no available dryer 31 for good crops (step S220: No), it calculates the waiting time (step S223) and transmits the waiting time and the number of the dryer 31 for good crops to, for example, the tablet terminal 42 on the side of the available dryer 31 (step S224).

[0096] Furthermore, in the processing of step S212, if the control device 40 determines that the use of the dryer 31 for good crops is permitted (step S212: Yes), it proceeds to the processing of step S220, i.e., determines whether or not there is an available dryer 31 for good crops (step S220), and if it determines that there is an available dryer 31 for good crops (step S220: Yes), it calculates the estimated time from the end of drying of the grains by the dryer 31 for good crops to the completion of discharge, calculates the order in which the multiple dryers 31 for good crops will become available, compares the order of the available dryers 31 (step S221), and transmits the number of the available dryer 31 to, for example, the tablet terminal 42 on the side of the available dryer 31 (step S222).

[0097] If the control device 40 determines that there is no available dryer 31 for good crops (step S220: No), it calculates the waiting time (step S223) and transmits the waiting time and the number of the dryer 31 for good crops to, for example, a tablet terminal 42 on the side of the available dryer 31 (step S224).

[0098] Furthermore, in the processing of step S212, if the control device 40 determines that use of the dryer 31 for good crops is not permitted (step S212: No), it performs processing of step S223, i.e., calculates the waiting time (step S223), and transmits the waiting time and the number of the dryer 31 for good crops to, for example, the tablet terminal 42 on the side of the available dryer 31 (step S224).

[0099] In this way, the control device 40 selects the dryer 31 to give priority to drying the grains that will be defective crops based on the time the grains are discharged from the combine 10, the remaining time for the grains from the combine 10, the estimated time from the end of grain drying to the completion of discharge, and the order in which the multiple dryers 31 for defective crops become available.

[0100] In addition, the control device 40 calculates the order in which each of the dryers 31, including those used for good crops other than the dryers 31 used for defective crops, will become available, and transmits the order in which the dryers 31 will become available to, for example, a tablet terminal 42 on the side of the available dryer 31.

[0101] Furthermore, when the control device 40 detects a position on the farm field map where the combine 10 has been subjected to a high harvesting load in the past, it calculates, at the start of harvesting by the combine 10, a priority order of the dryers 31 into which grains will be input (laid) from among the multiple dryers 31 (for example, the five dryers 31 A to B shown in FIG. 1) at the next discharge of the combine 10. Furthermore, the control device 40 causes a display unit such as a display screen of the tablet terminals 41 to 44 to display the priority order of the dryers 31.

[0102] Furthermore, when there is no available dryer 31 for preferentially drying grains that will be defective crops, the control device 40 changes the selected dryer 31 to be used for defective crops to another dryer 31 to be used for good crops. In this case, the control device 40 reserves the loading of grains (defective crops) into the changed dryer 31, and calculates the earliest loading time for this dryer 31. Furthermore, the control device 40 causes the loading time to be displayed on a display unit such as a display screen of the tablet terminals 41-44.

[0103] For example, as shown in FIG. 10, when the harvesting time of the culms of the defective crop by the combine 10 is "15:30", the discharge time of the grains of the defective crop threshed from the culms to the transport vehicle 20 is calculated as "16:00", and the transport time of the grains of the defective crop by the transport vehicle 20 is calculated as "16:30". In this case, among the dryers 31 A to E shown in FIG. 10, the dryer 31 E that can start drying at "17:00", which is the earliest time, is selected among the dryers 31 D and E set for the defective crops. Note that, for example, when the dryer 31 E is in use, the dryer 31 A set for the good crops can start drying at "17:00", so it is also possible to select the dryer 31 A.

[0104] According to the farm work management system 1 according to the embodiment described above, the harvesting load of the combine harvester 10 is used as an index of quality deterioration, and the position where the harvesting load of the combine harvester 10 becomes high (poor crop area A L ) crops are assumed to be of lower quality than standard crops, and thus the overall quality deterioration can be suppressed. Also, low-quality crops require drying differently from that required for crops of standard or higher quality, and by selecting a dryer 31 that gives priority to drying crops assumed to be of low quality, the waiting time for drying can be reduced. This improves work efficiency. In other words, it is possible to achieve both suppression of deterioration in crop quality and improvement of work efficiency.

[0105] In addition, the location where the harvesting load of the combine 10 was high (poor crop area A L By classifying crops of "low quality" as being of lower quality than standard crops, it is possible to prevent the overall quality deterioration from decreasing. In addition, by selecting a dryer 31 that will give priority to drying crops assumed to be of low quality, it is possible to reduce waiting time for drying and improve work efficiency.

[0106] In addition, by displaying the priority order of the dryers 31 to which grains are to be fed, the work efficiency can be further improved.

[0107] In addition, when there is no available dryer 31 that gives priority to drying crops assumed to be of low quality, the dryer 31 can be changed to reduce waiting times.

[0108] In addition, when there is no available dryer 31 that gives priority to drying crops assumed to be of low quality, the occurrence of waiting time can be reduced by changing the dryer 31. In addition, by reserving the dryer 31 and further displaying the loading time when grains can be loaded on the display unit and notifying the worker, the worker can take measures to reduce time loss, for example, according to the displayed loading time, and thus a decrease in work efficiency can be reduced.

[0109] In the above embodiment, the control device 40 determines the condition for assuming that the grain is a defective crop by determining whether the grain is a defective crop at a position where the harvesting load of the combine 10 is high (defective crop area A L In the above embodiment, the grains are classified as defective crops. However, other than this, for example, grains whose yield per unit area by the combine harvester 10 is less than a predetermined amount may be classified as defective crops. In this case, the control device 40 may, for example, determine the defective crop area A L In the process of determining whether or not the yield per unit area by the combine harvester 10 is equal to or less than a predetermined amount (step S101 in FIG. 8, step S201 in FIG. 9), L ) or not.

[0110] The control device 40 may also determine that grains are defective if the amount of protein in the grains when they are transported to the grain tank 17 is less than a predetermined amount as measured by a protein meter provided near the grain inlet of the grain tank 17. In this case, the control device 40 may determine that the grains are defective if the amount of protein in the grains is less than a predetermined amount as measured by a protein meter provided near the grain inlet of the grain tank 17. In this case, the control device 40 may determine that the grains are defective if they are in the defective crop area A shown in FIGS. L In the process of determining whether or not the amount of protein is equal to or less than a predetermined amount (step S101 in FIG. 8, step S201 in FIG. 9), L ) or not.

[0111] In the above embodiment, the control device 40 detects a position where the harvesting load of the combine 10 becomes high (the defective crop area A L ) is not included in the past location information held by server device 51, this location is additionally registered in the location information.

[0112] When the control device 40 adds a new location where the harvesting load has become high to the location information, it generates "interrupt information" that causes the combine 10 to harvest the stalks at the newly registered location, sort the grains from the harvested stalks, and select a dryer 31 corresponding to the sorted grains.

[0113] Based on the generated "interrupt information," when the combine harvester 10 starts harvesting, the control device 40 calculates the priority of the dryer 31 to which grains will be loaded the next time the combine harvester 10 discharges, and, for example, resets the reservation for loading grains into the dryer 31 with the highest priority.

[0114] According to such an agricultural work management system 1, in the field F, a position where the harvesting load is high (a defective crop area A L ) is continuously updated, the accuracy of the position information in the farm field map can be improved. In addition, by resetting the priority of the dryers 31 and the reservation of loading grains into the dryers 31 based on the interrupt information, it is possible to reduce waiting time and prevent a decrease in work efficiency.

[0115] In the above embodiment, the control device 40 detects the position where the cutting load is high (the defective crop area A L ) is registered in the position information in the field map, the travel speed of the combine harvester 10 may be controlled to be decelerated when the combine harvester 10 harvests at the same position from the following year onward. In addition, the control device 40 may be configured to detect the position where the harvesting load is high (the defective crop area A L ) the travel speed of the combine 10 may be controlled to return to the original speed.

[0116] Furthermore, in the above embodiment, the control device 40 selects the field F where the next harvesting operation will be performed. In this case, the control device 40 selects, for example, the field F where the absolute value of "grain drying time - (grain harvesting time + grain transport time)" is the smallest, as the field F where the next harvesting operation will be performed. The control device 40 also causes a display unit, such as a display screen of the tablet terminals 41-44, to display the field F where the next harvesting operation will be performed.

[0117] In addition, when priorities are set for each item, such as the movement time of agricultural machinery such as the combine 10, the control device 40 creates a work plan according to the worker's objectives, such as "I want to reduce the movement of the agricultural machinery between fields F" or "I want to reduce the waiting time for the dryer 31."

[0118] <Combine yield measurement configuration> A yield measurement configuration in the combine harvester 10 will be described with reference to Figures 11 and 12. Figure 11 is a diagram showing an example of a yield measurement configuration in the combine harvester 10. Figure 12 is a diagram showing another example of a yield measurement configuration in the combine harvester 10.

[0119] As shown in FIG. 11, the threshing device 15 of the combine harvester 10 includes a first angle sensor 151 and a second angle sensor 152. The first angle sensor 151 is provided at a position equivalent to a threshing depth sensor 155 provided at a supply portion of the culm PL1, which is upstream of the conveying direction of the culm PL1 in a threshing chamber 154 having a threshing body 153 ... T Detect the angle.

[0120] The second angle sensor 152 is provided near the entrance of the waste straw chain 156, which is downstream in the conveying direction of the culm PL1 (PL2) in the threshing chamber 154. The second angle sensor 152 is a sensor for detecting the tip PL2 of the culm (straw) PL2 from which the grains GR have been threshed from the culm PL1. T Detect the angle.

[0121] The control device 40 (see FIG. 1) detects the detection value of the first angle sensor 151 (the tip PL1 of the culm PL1T (angle of the culm PL2) and the detection value of the second angle sensor 152 (tip PL2 of the culm (straw) PL2 T The control device 40 compares the tip PL1 of the culm PL1 with the angle of the tip PL1 of the culm PL1. T angle and tip of culm (straw) PL2 PL2 T If the difference in the angles is large, the yield is judged to be high. T angle and tip of culm (straw) PL2 PL2 T If the difference in angles is small, the yield is judged to be low, and the judgment result is recorded.

[0122] Thus, the tip PL1 of the culm PL1 in the field F (see Figure 1) T and the tips of the culms (straw) PL2 PL2 T By determining the yield based on the angle difference and recording the amount of the yield, it is possible to record the growing condition of the crops in the field F. In this case, the control device 40 calculates which position in the field F the position where the yield is recorded corresponds to, from the traveling speed of the combine 10. Note that the minimum interval for recording the yield is preferably about 3 meters. Also, the interval for recording the yield can be changed as desired.

[0123] In addition, the control device 40 records the position where the reaping device 14 (see Figs. 2 and 3) descends and starts the reaping operation as the start position of the reaping work, and starts the yield recording. This eliminates the need to manually start the yield recording.

[0124] The control device 40 may also control the combine harvester 10 to start recording the yield when the combine harvester 10 reaches a desired distance calculated from the traveling speed of the combine harvester 10. In this case, the tip PL1 of the culm PL1 T and the tips of the culms (straw) PL2 PL2 T The average value of the difference between the previous angle and the previous angle is recorded. T and the tips of the culms (straw) PL2 PL2 T The median angle difference from the previous angle is recorded.

[0125] In addition, since the second angle sensor 152 is not coaxial with the rotation shaft 153a of the threshing body 153, the space required for providing the second angle sensor 152 can be reduced, and the second angle sensor 152 can be easily installed in the combine harvester 10. Note that, as shown in FIG. 12, the second angle sensor 152 may be provided coaxially with the rotation shaft 153a of the threshing body 153.

[0126] <Grain storage configuration in combine harvester> The grain storage configuration in the combine harvester 10 will be described with reference to Fig. 13. Fig. 13 is a diagram showing an example of the grain storage configuration in the combine harvester 10.

[0127] The combine harvester 10 has a function of dividing the grain storage area according to the protein content, which indicates the taste. The combine harvester 10 is a so-called robot combine harvester that automatically operates using position information from a positioning device 11 (see Figs. 2 and 3).

[0128] As shown in Fig. 13, the grain tank 17 of the combine harvester 10 is divided into two in the front-rear direction by a partition plate 17a. The combine harvester 10 stores grains in either the front tank 17b or the rear tank 17c depending on the protein content, etc. The grain tank 17 may be divided into three or more tanks.

[0129] The combine harvester 10 may also divide the storage locations according to factors other than protein content, such as the moisture content of the grains or the harvesting position in the field F (see FIG. 1). The combine harvester 10 sets priorities for the protein content, moisture content, harvesting position, and the like, and sets storage locations for the grains according to the priorities. In this case, the grains with the higher priority are stored in the rear tank 17c. The combine harvester 10 displays such priorities, and can arbitrarily switch the priorities by operating a switch, for example.

[0130] <Field mapping using information from combine harvesters> The control device 40 generates a field map (field mapping) using information acquired from the combine harvester. In this case, the control device 40 generates swell information for the field F based on the detection value of a ground sensor provided on the harvester 14 (see Figs. 2 and 3) of the combine harvester 10, and registers the swell information in the field map. The control device 40 also registers the position where the jam sensor of the combine harvester 10 detected a jam of culms or the like in the field map. In this way, by registering the swell information for the field F and the position where the jam of culms or the like occurred in the field map, it can be used for work in the following year and thereafter, and work losses in the following year and thereafter can be reduced.

[0131] After the blockage of culms or the like is cleared, the cause of the blockage (for example, overload during harvesting, stubble coming loose, crop lodging, etc.) can be input and used in the following years' work, such as changing the response in the following years' work. Also, in the following years' work, the control device 40 can issue an alert just before the location where the blockage of culms or the like occurred, thereby reducing work losses in the following years' work.

[0132] If the cause of the jam is an overload during harvesting, the control device 40 slows down the combine harvester 10. This makes it possible to reduce work loss. If the cause of the jam is stubble removal, the control device 40 increases the height of the harvester 14. This makes it possible to reduce work loss. If the cause of the jam is crop lodging, the control device 40 switches the combine harvester 10 to a lodging mode. This makes it possible to reduce work loss. If the control device 40 determines that the cause is long culms (long culms) based on the location of the jam in the field map and the length of the culms, the control device 40 adjusts the threshing depth to shallow threshing.

[0133] In addition, the control device 40 generates swell information for the field F based on the detection values ​​of horizontal sensors installed on the left and right sides of the combine 10's body, and registers the swell information in a field map so that it can be used for work in the following year and beyond.

[0134] In the combine harvester 10, the length from the feed chain of the threshing device 15 (see Figs. 2 and 3) to the tip side of the culm can be calculated to be midway between the base sensor and the tip sensor, so that the accurate length of the harvested culm can be calculated. The length from the feed chain to the base side of the culm can be calculated from the detection value of the ground sensor and the position of the motor, so that the accurate length of the harvested culm can be calculated. The control device 40 registers the value (length) obtained by adding the detection value of the ground sensor of the harvesting device 14 to the calculated culm length as the actual culm length. The control device 40 registers the positions not detected by the culm length sensor in the field map as being less than a predetermined specified length. This makes it possible to realize the field mapping with the current configuration.

[0135] In the combine harvester 10, by providing the ground sensor of the harvesting device 14 in the center of the harvesting device 14, it becomes easier to detect not only swells in the direction of travel (front-back direction) of the machine body, but also swells in the left-right direction of the machine body.

[0136] In addition, by setting multiple locations where the stalks or other clogging may occur (for example, the harvesting area, the handover area, the cutter area, the waste straw area, etc.), it is possible to reduce work losses in the following years. In this case, for example, the control device 40 notifies the operator to check the handover area at the location where the clogging occurred in the cutter area during work in the following years or later.

[0137] Furthermore, when an abnormality occurs in the combine harvester 10, the control device 40 transmits an abnormality code from the engine or machine controller (control unit 411), displays the occurrence of the abnormality on the monitor 109, and acquires and records abnormality information and position information from the GNSS device controller, which is the positioning device 11. As a result, while the abnormality display remains the same as before, GNSS-related information can be consolidated in the GNSS device controller, and the capacity of the monitor 109 can also be reduced.

[0138] The control device 40 also combines the recorded abnormality information and position information with map information on yield and variable fertilization. In this way, by combining with map information other than that of the combine harvester 10, this information can be used to analyze other tasks.

[0139] The control device 40 also accumulates map information in the tablet terminal 41 or the like and manages the map information. This allows analysis and management at a location other than the field F. In this case, the map information is displayed as a map on a display screen (display unit) of the tablet terminal 41 or the like. This allows the worker to visually recognize the location where the abnormality has occurred. The map information is also displayed as a map on a display screen (display unit) of the tablet terminal 41 or the like by arbitrarily combining different information such as abnormality information and yield information. This allows each piece of information to be compared and displayed, making analysis easier. The control device 40 has automatic analysis items and displays the analysis items on a display screen (display unit) of the tablet terminal 41 or the like. For example, crop lodging information is set as an analysis item. When abnormality information such as clogging of stalks and variable fertilization information meet a standard, the control device 40 displays a result such as reducing fertilizer.

[0140] According to the embodiment described above, the following farm work management system 1 is realized.

[0141] (1) A system is provided with a combine harvester 10 that harvests and threshes stalks while traveling within a farm field F, a transport vehicle 20 that transports the grains threshed by the combine harvester 10, a plurality of dryers 31 that dry the grains transported by the transport vehicle 20, and a control device 40, in which the combine harvester 10, the transport vehicle 20, the dryers 31, and the control device 40 are communicatively connected, the control device 40 acquires a farm field map and position information within the farm field map, and registers information regarding the crops in the farm field F, including information acquired from the combine harvester 10, in the position information, and the information regarding the crops is stored in the control device 40. L ), and the position where the harvesting load of the combine 10 was high (the defective crop area A L) and separate grains from the harvested stalks in the multiple dryers 31 at the locations where the harvest load of the combine 10 is high (the defective crop area A L The agricultural work management system 1 selects a dryer 31 that preferentially dries grains from the harvested stalks in the agricultural work management system 1.

[0142] Conditions under which the harvesting load of the combine harvester 10 becomes high include the falling of crops (grain culms) and the muddy soil surface of the field F, but such conditions are not conducive to growing crops of good quality (such as rice grains). According to the agricultural work management system 1, the harvesting load of the combine harvester 10 is used as an index of quality deterioration, and the position where the harvesting load of the combine harvester 10 becomes high (poor crop area A L ) are assumed to be of lower quality than standard crops and classified as such, thereby making it possible to prevent an overall decline in quality. Also, low-quality crops require drying differently from that required for crops of standard or higher quality, and by selecting a dryer 31 that gives priority to drying crops assumed to be of low quality, it is possible to reduce waiting time for drying. This makes it possible to improve work efficiency. In other words, such an agricultural work management system 1 makes it possible to both prevent a decline in crop quality and improve work efficiency.

[0143] (2) In the above (1), the control device 40 calculates the transport time of the grain from the combine 10 to the drying facility 30 based on the position information and the position of the drying facility 30 in which the dryer 31 is installed, calculates the grain discharge time from the machine performance and the harvesting amount among the information obtained from the combine 10, calculates the remaining time until the next grain discharge from the remaining capacity of the grain tank 17 and the harvesting performance per unit time among the information obtained from the combine 10, calculates an estimated time from the end of drying of the grain by the dryer 31 to the completion of discharge and calculates the order in which the multiple dryers 31 will become available, and determines the position where the harvesting load of the combine 10 is high (defective crop area A) based on the discharge time, remaining time, estimated time and the order in which the multiple dryers 31 will become available. LThe agricultural work management system 1 calculates the order in which a dryer 31 that gives priority to drying grains from the harvested stalks in the first stalk 20 and the dryers 31 other than this dryer 31 become available.

[0144] According to such an agricultural work management system 1, in addition to the effect of (1) above, the position where the harvesting load of the combine 10 is high (the defective crop area A L By classifying crops of "low quality" as being of lower quality than standard crops, it is possible to prevent the overall quality deterioration from decreasing. In addition, by selecting a dryer 31 that will give priority to drying crops assumed to be of low quality, it is possible to reduce waiting time for drying and improve work efficiency.

[0145] (3) In the above (2), a display unit that is controlled by the control device 40 and can display various information is further provided, and the control device 40 displays a position on the farm field map where the harvesting load of the combine 10 was high in the past (a poor crop area A L When the control device 40 detects a start of harvesting by the combine harvester 10, the agricultural work management system 1 calculates the priority of the dryer 31 to which grains will be laid at the next discharge of the combine harvester 10 when the combine harvester 10 starts harvesting, and the display unit displays the priority calculated by the control device 40.

[0146] According to such a farm work management system 1, in addition to the effect of (2) above, the work efficiency can be further improved by displaying the priority order of the dryers 31 to which grains are charged.

[0147] (4) In the above (3), the control device 40 detects the position where the harvesting load of the combine 10 becomes high (the defective crop area A L In the case where there is no available dryer 31 that prioritizes drying grains from the harvested stalks in the agricultural work management system 1, the selected dryer 31 is changed to another dryer 31.

[0148] According to such an agricultural work management system 1, in addition to the effect of (3) above, if there is no available dryer 31 that gives priority to drying crops assumed to be of low quality, the dryer 31 can be changed, thereby reducing waiting time.

[0149] (5) In the above (4), the control device 40 detects the position where the harvesting load of the combine 10 becomes high (the defective crop area A L In the case where there is no available dryer 31 that prioritizes drying of grains from harvested stalks in the agricultural work management system 1, the selected dryer 31 is changed to another dryer 31, the loading of grains into the changed dryer 31 is scheduled, and the earliest loading time for this dryer 31 is calculated, and the display unit displays the loading time calculated by the control device 40.

[0150] In addition to the effect of (4) above, such an agricultural work management system 1 can reduce waiting time by changing the dryer 31 when there is no available dryer 31 that gives priority to drying crops assumed to be of low quality. Also, by reserving the dryer 31 and displaying the loading time when grains can be loaded on the display unit and notifying the worker, the worker can take measures to reduce time loss, for example, according to the displayed loading time, and thus it is possible to prevent a decrease in work efficiency.

[0151] (6) In the above (5), the control device 40 detects the position where the harvesting load of the combine 10 becomes high (the defective crop area A L If the position is not included in the past position information, this position is added to the position information, and the position where the harvesting load of the combined harvester 10 that has been added is high (the bad crop area A LThe agricultural work management system 1 generates interruption information for harvesting the culms in the harvested culms, separating the grains from the harvested culms, and selecting a dryer 31 corresponding to the separated grains, and calculates the priority of the dryer 31 to which the grains are to be loaded at the next discharge of the combine harvester 10 when the combine harvester 10 starts harvesting based on the interruption information, and resets the reservation for loading the grains into the dryer 31.

[0152] According to such an agricultural work management system 1, in addition to the effect of (5) above, in the field F, the position where the harvesting load is high (the defective crop area A L ) is continuously updated, the accuracy of the position information in the farm field map can be improved. In addition, by resetting the priority of the dryers 31 and the reservation of loading grains into the dryers 31 based on the interrupt information, it is possible to reduce waiting time and prevent a decrease in work efficiency.

[0153] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
