May transmit to the production management computer 33C, the work plan stored in the production management computer 33C may be converted into an agricultural result. In this case as well, agricultural results and planting plans are automatically associated.

By the way, when the grain is harvested, as shown in FIG. 6, the grain harvested by the combine 20 is put into the first accommodating member 55 of the truck which is the carrier 53. The grain placed in the first containing member 55 is transported by a truck 53 to a grain processing facility 60 such as a rice center. The first accommodation member 55 is a container or the like.
In the production management system, it is possible to set which first containing member 55 contains grains with the amount of water and protein. That is, in the crop management system, it is possible to associate crop information (a crop name, a harvest amount, a moisture amount at harvest, a protein amount at harvest) and the first accommodation member 55 with each other.

Next, the correspondence between the crop information and the first accommodation member will be described.
Correspondence between the crop information and the first accommodation member 55 is performed using the communication terminal 33A or the like. The communication terminal 33A includes an identification acquisition unit 57 and an association unit 58.
As shown in FIG. 7, the display unit 39 of the communication terminal 33A can display a machine selection screen Q5 for selecting an agricultural machine such as the combine 20 or the like. In the machine selection screen Q5, a list of combine names corresponding to the combine 20 owned is displayed. When a predetermined combine name (harvestor) is selected on the machine selection screen Q5, the communication terminal 33A holds the machine identification information corresponding to the selected combine name.

  The identification acquisition unit 57 acquires identification information (referred to as accommodation identification information) for identifying the first accommodation member 55. The accommodation identification information is configured by a unique number or the like. The storage identification information is attached to the QR code (registered trademark) attached to the first storage member 55. The identification acquisition unit 57 is configured of a camera or the like, and holds the storage identification information by reading a QR code (registered trademark) as an image. The associating unit 58 associates the machine identification information corresponding to the combine name (the harvester) selected on the machine selection screen Q5 with the storage identification information indicating the first containing member 55 acquired by the identification acquisition unit 57.

When associating the machine identification information with the storage identification information, the associating unit 58 also associates the consignment information assigned for management. The consignment information is an ID code or the like, and is constituted by a unique number or the like. For convenience of explanation, the ID code used as consignment information is called consignment ID.
Therefore, as shown in FIG. 8, the combine 20 which harvested the grain, ie, machine identification information for identifying the combine 20, and the first containing member 55 containing the grain harvested by the combine 20, ie, storage identification information Can be associated. The relationship between the predetermined combine 20 and the predetermined first housing member 55 can be extracted by the consignment ID.

Further, the communication terminal 33A can associate the predetermined first containing member 55 with the water content and the protein amount of the grain stored in the first containing member 55. This association is performed using various information. For convenience of explanation, the combine 20 selected on the machine selection screen Q5 is selected, the machine identification information indicating the selected combine is selected identification information, and the predetermined first housing member 55 associated with the selected combine is selected. The determination accommodating member indicates the accommodation identification information indicating the determination accommodating member as the determination identification information.

  The associating unit 58 refers to the second storage unit 36 of the communication terminal 33A, and determines whether or not there is crop information on the grain harvested by the selected combine. For example, if there is crop information corresponding to selection identification information indicating selection combine in the second storage unit 36, it is determined that there is crop information in the grain harvested by the selection combine. Here, when there is crop information, the associating unit 58 indicates items (field, harvest date, working time, information on workers, machines, etc.) indicated in the agricultural results converted from the work plan, and communication terminals in advance. Using the time information (year, month, day, hour, minute, etc.) possessed by 33A, crop information (the amount of water at harvest, the amount of protein at harvest) in the grain housed in the determined storage member is extracted. The associating unit 58 extracts, for example, an agricultural result having the same harvest date as the date when the combine 20 or the first accommodation member 55 is selected on the machine selection screen Q5 in the second storage unit 36, and corresponds to the extracted agricultural result The amount of water and protein to be contained is assumed to be possessed by the grain contained in the determination containing member. That is, the associating unit 58 associates the moisture amount at harvest and the protein amount at harvest which is the extracted crop information with the storage identification information indicating the determined storage member.

In the embodiment described above, the determination storage member (housing identification information) and the crop information are associated by referring to the second storage unit 36 of the communication terminal 33A, but the management information storage unit 47 of the production management computer 33C You may match accommodation identification information and crop information by referring.
For example, the association unit 58 uses the production management computer as a search key with items (field, harvest date, working hours, workers, information about machines, etc.) and selected identification information indicated in the agricultural results converted from the work plan. Send to 33C. Then, the association unit 58 extracts the crop information harvested by the selective combine from the management information storage unit 47 using the search key. Then, the associating unit 58 associates the crop information extracted from the management information storage unit 47 with the determined containing member (accommodating identification information).

  Therefore, as shown in FIG. 9, the storage identification information and the crop information (the amount of harvest, the amount of water at the time of harvest, the protein at the time of harvest, are retrieved by searching the second storage unit 36 or the management information storage unit 47. Amount) can be associated. The associated crop information and storage identification information are stored together with the consignment information in the harvest information storage unit 48 provided in the production management computer 33C.

  In addition to the association between the crop information and the predetermined first housing member 55, operation information (agricultural results) may also be associated. For example, the communication terminal 33A is connected to the production management computer 33C, and an agricultural result (for example, harvested field, worker name, etc.) corresponding to the crop information is extracted from the management information storage unit 47, as shown in FIG. The extracted agricultural record, crop information, storage identification information, and consignment ID may be associated with each other and stored in the harvest information storage unit 48. Moreover, matching with accommodation identification information and crop information is not limited to the method mentioned above.

As described above, according to the production management system, for example, it is possible to collectively manage crop planting plans, agricultural work work plans, agricultural work results (work information), information on crop harvesting (crop information), and the like.
Next, the crop management system will be described. The crop management system is mainly a system for managing crops after harvest (grains). Specifically, the crop management system is a system that manages a grain processing facility 60 that processes crop crops (grains) after harvest.

First, the grain processing facility 60 will be described.
As shown in FIG. 11, the grain processing facility 60 includes a plurality of processors 61. The processor 61 is, for example, a dryer 61A, a heat radiation tank 61B, a huller 61C, a color separator 61D, a weighing device 61E, and the like. In addition, a processor is not limited to what was mentioned above.
As shown in FIGS. 12-14, the drier 61A is an apparatus for drying grain. The dryer 61 </ b> A includes an input unit 62, a storage unit 63, a drying unit 64, a circulation unit 65, and a measuring device 66.

  The input unit 62 has an input port 62A for inputting the grain to be dried, and is constituted by a hopper or the like. The storage unit 63 and the drying unit 64 are provided in a first main body 67 formed in a box shape. The storage section 63 is a room for storing the grains to be dried, and is provided at the upper portion of the first main body 67. The drying unit 64 is an apparatus for drying the grain by heat or the like, and is provided in the first main body 67 below the storage unit 63. The storage unit 63 and the drying unit 64 communicate with each other, and the grain stored in the storage unit 63 flows to the drying unit 64.

  The circulation unit 65 is an apparatus for circulating the grain, and is an apparatus for sending the grain dried by the drying unit 64 to the storage unit 63 or sending the grain input to the input unit 62 to the storage unit 63. The circulation unit 65 includes a crossfeed mechanism 65A that crossfeeds the dried grain, and a vertical feed mechanism 65B that feeds the grain fed by the crossfeed mechanism 65A upward. First, the vertical feed mechanism 65B will be described.

The vertical feed mechanism 65B is provided with a box-shaped second main body 70 provided laterally of the first main body 67 and elongated vertically, and a carrying portion 71 provided inside the second main body 70 and carrying grain upward. ing.
The second main body 70 has a bottom wall 70A and a peripheral wall 70B rising from the periphery of the bottom wall 70A. At the lower part of the peripheral wall 70B, a receiving port 70C for receiving the grain fed by the crossfeed mechanism 65A is formed.

  The transport unit 71 includes rotatable sprockets 71A disposed at the upper and lower portions of the second main body, a belt 71B hung on the upper and lower sprockets 71A, and a bucket 71C provided on the belt 71B. According to the vertical feed mechanism 65B, the grain of the lower part of the second main body 70 is covered with the bucket C71 and moved to the upper part of the second main body 70 by moving the belt 71B by rotating the sprocket 71A with a drive motor or the like (not shown). It can be transported. The grain conveyed to the upper part of the second main body 70 is conveyed to the reservoir 63 through the communication part 72 connecting the upper part of the second main body 70 and the first main body 67.

  The crossfeed mechanism 65 </ b> A is provided below the first main body 67 and below the drying unit 64. The crossfeed mechanism 65A has a screw 73 capable of laterally feeding the grain, and a flow passage 74 for flowing the grain laterally fed by the screw 73 to the longitudinal feed mechanism 65B. Specifically, a transfer chamber 75 is formed, which is a lower part of the first main body 67 from one side (left side in FIG. 12) to the other side (right side in FIG. 12), into which the grains dried by the drying unit 65 enter. A screw 73 is provided along the transfer chamber 75. The screw 73 is rotatably supported in the transfer chamber 75, and can rotate grains in the transfer chamber 75 toward the flow passage 74 by being rotated by a driving force such as a drive motor.

The flow passage 74 connects the lower portion of the first main body 67 and the second main body 70. Specifically, the flow passage 74 is a passage connecting the transfer chamber 75 and the lower portion of the peripheral wall 70B of the second main body 70, and includes a bottom wall 74A, a pair of vertical walls 74B, an upper wall 74C, and a first It is comprised by connection wall 74D and the 2nd connection wall 74E.
The bottom wall 74A is formed of a plate material extending from the transfer chamber 75 toward the second main body 70, and the end of the bottom wall 74A is connected to the inlet 70C. The pair of vertical walls 74B is formed of a plate material rising from the bottom wall 74A, and the upper wall 74C is formed of a plate material connecting the upper ends of the vertical walls 74B.

  The first connection wall 74D is formed of a plate connecting the end of the bottom wall 74A (right end in FIG. 12), the end of the pair of vertical walls 74B and the end of the upper wall 74C (right end in FIG. 12) ing. The second connection wall 74E is formed of a plate member connecting the middle portion of the bottom wall 74A and the vertical wall 74B facing the second main body 70 of the pair of vertical walls 74B. In addition, the flow path 74 is not limited to the structure mentioned above, You may be comprised by bottom wall 74A and a pair of vertical wall 74B, and may be comprised by the other wall.

In the inner surface (conveyance surface) of the bottom wall 74A, the conveyance surface between the first connection wall 74D and the second connection wall 74E is inclined downward moving toward the peripheral wall 70B of the second main body 70. ing. In other words, in the transport surface of the bottom wall 74A, the portion overlapping the second main body 70 in the width direction is inclined to shift downward as it approaches the peripheral wall 70B.
That is, the flow passage 74 has the inclined surface 74F which is shifted downward as the second main body 70 is approached. The end of the inclined surface 74F is connected to the inlet 70C. The width of the inclined surface 74F is set to be substantially the same as the width of the lower portion of the second main body 70. Therefore, when the grain flowing in the flow passage 74 reaches the inclined surface 74F, the grain 74 slides down the inclined surface 74F and falls below the second main body 70. Therefore, on the inclined surface 74F, the grain is likely to spread uniformly, and the thickness of the grain layer at the time of transportation of the grain is a position where the thickness of the grain layer is easily reduced.

  The measuring device 66 is a device for measuring the characteristics of grains, and is constituted by a near infrared moisture meter. A near-infrared moisture meter is a device that measures moisture (water content), which is one of the characteristics of cereals, by irradiating the cereals with infrared radiation. With the near infrared moisture meter, it is possible to measure the moisture content of grain at intervals of several tens of seconds. The water content measured by the near infrared moisture meter is a ratio to the mass (water content%).

Such a measuring device 66 is provided in the circulation unit 65, and measures at least the moisture content of the grain (grain after drying) dried by the drying unit 64. Specifically, the measuring device 66 is provided in a crossfeed mechanism 65A that crossfeeds the dried grain. By providing the crossfeed mechanism 65A with the measuring device 66, the moisture content of the grain fed laterally after drying can be accurately measured.
Specifically, the measuring device 66 is provided in the flow passage 74 of the cross feed mechanism 65A and on the bottom wall 74A. A window 74G is formed on the inclined surface 74F of the bottom wall 74A, and the measuring device 66 is attached to the outside of the window 74G which constitutes a part of the inclined surface 74F. The optical axis of the measuring device 66 (optical axis for irradiating infrared rays) is directed to the window 74G, and the measuring device 66 measures the moisture content of the grain flowing on the inclined surface 74F (window 74G). According to this, it is possible to measure the moisture content of the grain flowing on the inclined surface 74F while spreading uniformly by the measuring device 66. That is, the amount of water in the majority of cereals that circulate after drying can be measured by the measuring device 66. In this embodiment, the moisture amount of the grain flowing on the inclined surface 74F is measured by mounting the measuring device 66 on the inclined surface 74F of the flow passage 74. However, as shown in FIG. For example, the moisture content of the grain flowing on the inclined surface 74F may be measured by mounting the inclined surface 74F above and orienting the optical axis of the measuring device 66 to the inclined surface 74F.

  As shown in FIG. 13, the input part (hopper) 62 is provided above the inclined surface 74F. The lower end portion of the hopper 62 is connected to an upper wall 74C opposite to the inclined surface 74F. Since the hopper 62 is provided above the inclined surface 74F and the measuring device 66 is provided on the inclined surface 74F, the water content of the grain immediately after the hopper 62 is charged can be measured by the measuring device 66. After drying, the moisture content of the grain flowing on the inclined surface 74 can be measured.

As shown in FIG. 11, the drier 61A includes a first control unit (first controller) 80A, which includes a CPU or the like, and a display device 68 that performs various displays.
A measuring device 66 is connected to the first controller 80A. The first controller 80A performs various calculations on the dryer based on the amount of water measured by the measuring device 66.

The calculation by the first controller 80A will be described.
The first controller 80 </ b> A includes a dryness reduction rate calculation unit 90. The dry ratio calculation unit 90 is composed of a program stored in the first controller 80A, an electronic circuit, and the like. The dry ratio calculation unit 90 calculates a dry ratio, which is a decrease in water content per unit time, based on the water content measured by the measuring device (near red moisture meter) 66. For convenience of explanation, the amount of water measured by the measuring device (near red moisture meter) 66 is referred to as “measured water amount”.

After the drying by the dryer 61A starts, the dryness reduction rate calculation unit 90 acquires the measured water content at predetermined time intervals (for example, every 30 seconds to 60 seconds). Then, the drying rate calculation unit 90 uses all the measured moisture amounts measured as shown in FIG. 16A when the measured moisture amount is more than a predetermined amount, for example, when the number of measured moisture amounts becomes 5 or more. The reduced approximation line L1 (intercept, slope) indicating the decreasing rate of the measured water content is determined by the least squares method. Then, the dry reduction rate calculation unit 90 determines the decrease approximate line L1 as the decrease approximate line L2 per unit time, as shown in FIG. 16B, based on the measurement interval of the measured water content and the parameter indicating the decrease approximate line L1. Convert to (intercept, slope). The slope of the decrease approximate line L2 is the rate of dryness. For example, the dry ratio calculation unit 90 obtains a dry ratio per 1 minute (60 seconds). The dry reduction rate calculation unit 90 obtains the slope of the reduction approximate line L2, which is the dry reduction rate, using the already-measured measured moisture amount every time the measured moisture amount is measured. In the embodiment described above, the reduced approximate line L1 is converted to a reduced approximate line L2 (intercept, slope) per unit time after obtaining the reduced approximate line L1 (intercept, slope). The calculation of L1 may be omitted, and the slope (the rate of dryness) of the reduced approximate line L2 may be determined.

The first controller 80 </ b> A includes a moisture non-uniformity calculation unit 91. The moisture unevenness calculation unit 91 is configured of a program stored in the first controller 80A, an electronic / electrical circuit, and the like. The water unevenness calculation unit 91 calculates water unevenness which is the difference between the maximum value and the minimum value of the water content, based on the water content measured by the measuring device (near red moisture meter) 66.
The moisture non-uniformity calculation unit 91 causes the dry reduction rate calculation unit 90 to determine the slope (dry reduction rate) of the reduction approximate line L2, and then the dry reduction rate and the time elapsed since the start of drying (elapsed time) And correct the measured moisture value based on Specifically, the moisture non-uniformity calculation unit 91 obtains the corrected moisture amount according to “corrected moisture amount = measured moisture value × elapsed time (elapsed time at the time when the measured moisture value is measured)”. When the corrected moisture content is determined corresponding to the decrease approximate line L2 shown in FIG. 16B, the correction line L3 after the corrected moisture content is corrected is as shown in FIG. 16B.

The moisture non-uniformity calculation unit 91 obtains a difference between the maximum value of the corrected moisture content and the minimum value of the corrected moisture content (a difference between the maximum value and the minimum value of the moisture content) based on the corrected moisture content Moisture unevenness. In the case of the correction line L3 in FIG. 16B, the maximum value of the corrected moisture amount is 15.91%, and the minimum value of the corrected moisture amount is 15.74%, so the moisture unevenness is 0.2%. .
In the embodiment described above, the moisture non-uniformity calculation unit 91 corrects the measured moisture amount based on the dry reduction rate and the elapsed time, and the difference between the maximum value and the minimum value of the corrected moisture amount after the correction is the moisture non-uniformity. However, it may be possible to determine the moisture unevenness using the measured moisture amount itself. That is, the moisture non-uniformity calculation unit 91 may obtain the moisture non-uniformity from the difference between the maximum value and the minimum value of the measured moisture amount which is the actual measurement value.

The first controller 80A includes a target acquisition unit 92 and a time calculation unit 93. The target acquisition unit 92 and the time calculation unit 93 are composed of a program stored in the first controller 80A, an electronic / electrical circuit, and the like.
The target acquisition unit 92 acquires a target water content, which is a target water content of the grain after drying by the drier 61A. The target acquisition unit 92 acquires a target water content from the display device 68 of the dryer 61A, or acquires a target water content from a crop management computer described later.

  Specifically, in the display device 68 or the crop management computer, for example, an input interface provided in the display device 68 or the crop management computer can set a target moisture amount for a predetermined drying process. The target acquisition unit 92 requests the display device 68 or the crop management computer for the target moisture amount for the predetermined drying process, and acquires the target moisture amount transmitted from the display device 68 or the crop management computer. In addition, the target acquisition unit 92 automatically acquires the target moisture amount transmitted from the display device 68 or the crop management computer without necessarily requesting the target moisture amount to the display device 68 or the crop management computer. May be

  The time calculation unit 93 calculates the arrival time to reach the target water content based on the measured water content and the target water content with the measurement device (near red moisture meter) 66. Specifically, the time calculation unit 93 uses the measured moisture amount at the start of drying by the dryer 61A, the target moisture amount, and the dry reduction rate calculated by the dry reduction rate calculation unit 90 to obtain the target moisture amount. Calculate the arrival time to reach. The time calculation unit 93 obtains the arrival time by “arrival time = (measured water amount at start of drying−target water amount) / dry reduction rate”. The calculation of the arrival time by the time calculation unit 93 is not limited to the embodiment described above. For example, the time calculation unit 93 may obtain the arrival time by “reached time = (current measured moisture amount−target moisture amount) / dry reduction rate” every time the measured moisture amount is measured, or the actual measurement The arrival time may be determined using the measured water content and the rate of dryness when the water content is close to the target water content.

As described above, since the first controller 80A includes the dry ratio calculation unit 90, the moisture non-uniformity calculation unit 91, and the time calculation unit 93, the dry reduction ratio, the moisture non-uniformity, and the arrival time are determined based on the measured moisture content. It can be determined by the amount of water measured.
In the above-described embodiment, the first controller 80A includes all of the dry ratio calculation unit 90, the moisture unevenness calculation unit 91, and the time calculation unit 93, but instead, the dry ratio calculation unit 90, Either the moisture unevenness calculating unit 91 or the time calculating unit 93 may be provided.

  When the first controller 80A actually reaches the arrival time, the moisture content of the grain may be measured by the measuring device 66, and the measured moisture content may be used as a representative moisture content after the drying of the dryer 61A is completed. Also, at the timing when the moisture content of the grain is measured by the measuring device 66 in the dryer 61A, the measured moisture content may coincide with the target moisture content, but the measured moisture content is slightly less than the target moisture content Sometimes. That is, in the measuring device 66, for example, when the 30th time exceeds the target moisture content and the 31st time falls below the target moisture content, the first controller 80A measures the 31st measurement result (the moisture content measured) The representative amount of water after completion of the drying of the drier 61A. That is, the first controller 80A monitors the water content measured by the measuring device 66, and uses the measured value less than the target water content and closest to the target water content as the representative water content after the end of the drying.

  The display device 68 displays the measured water content, the dry reduction rate, the water unevenness, and the arrival time described above. For example, by the input interface of the display device 68, the modes of "water content display", "drying loss ratio display", "water content nonuniformity display", and "elapsed time display" can be selected. When “moisture display” is selected, as shown in FIG. 17A, the display device 68 displays the transition of the measured water amount corresponding to the measurement point by a line graph or the like on the display unit 68A such as liquid crystal. When “dry reduction rate display” is selected, as shown in FIG. 17B, the display device 68 displays the decrease approximate line L2 and the dry reduction rate on the display unit 68A.

  When “moisture unevenness display” is selected, as shown in FIG. 17C, the display device 68 displays the transition of the corrected water amount corresponding to the measurement point on the display unit 68A by a line graph or the like, and corrects it. Display the maximum and minimum water content. In addition, when “water non-uniformity display” is selected, instead of the corrected water content, the transition of the measured water content which is the measured value, and the maximum value and the minimum value of the measured water content may be displayed.

  Furthermore, when “display elapsed time” is selected, as shown in FIG. 17D, the display device 68 displays the decrease approximate line L2 corresponding to the elapsed time and the arrival time on the display unit 68A. The display of the arrival time may be represented by the time to reach the target water content (drying end time), or is represented by the remaining time (for example, 15 minutes) from the current time until the target water content is reached. Alternatively, it may be represented by a total length (for example, 300 minutes) from the start of the drying process to reaching the target moisture content, or may be another indication.

In the embodiment described above, the display device 68 is configured to display all of the measured water content, the dry reduction rate, the water unevenness, and the elapsed time, but instead, the measured water amount, the dry reduction rate, It may be a device that displays either moisture unevenness or elapsed time.
Now, the first controller 80A controls the dryer 61A based on the measured water content. The first controller 80A performs, for example, “dry reduction rate control” which is control based on the dry reduction rate, and “nonuniformity removal control” which is control based on the moisture unevenness.

The first controller 80A includes a drying control unit 95 that performs "dry ratio control". The drying control unit 95 is configured of a program stored in the first controller 80A, an electronic circuit, and the like.
The dry reduction control unit 95 controls the drying unit 64 based on the dry reduction rate obtained by the dry reduction rate calculation unit 90. For example, as shown in FIG. 18, the dryness control unit 95 determines, based on the present dryness ratio (the currently calculated dryness ratio) calculated by the dryness ratio calculation unit 90, a predetermined time after a predetermined time from the present. Predict the water content at P1. That is, the drying control unit 95 obtains the predicted moisture amount at the predetermined time point P1 using the currently calculated drying ratio. Then, the dryness reduction control unit 95 obtains the difference between the predicted water content at the predetermined time point P1 and the measured water content (predicted water content-measured water = difference between dry loss rate), and in the case where the dry loss rate difference is negative, Assuming that the drying has not progressed, the output of the burner output from the drying unit 64 is increased according to the difference in the dry reduction rate. On the other hand, the drying control unit 95 deduces the output of the burner output from the drying unit 64 according to the drying reduction rate difference on the assumption that the drying progresses too much when the drying reduction rate difference is positive.

In the embodiment described above, the dry reduction control unit 95 changes the output of the burner based on whether the dry reduction rate difference is positive or negative, but the dry reduction rate difference is predetermined. It is determined whether or not it is above the threshold (determination value), and if it is above the threshold, control may be performed to change the output of the burner according to the size of the threshold. If the dry reduction rate difference does not become positive or negative above the threshold, the output of the burner is not changed.

  Also, the drying control unit 95 may perform the drying reduction control, for example, based on the current drying reduction ratio (the currently calculated drying reduction ratio) and a predetermined drying reduction ratio (setting drying reduction ratio). Good. For example, the drying control unit 95 sets the output of the burner output from the drying unit 64 as the currently calculated drying ratio, assuming that the drying is progressing too much if the currently calculated drying ratio is larger than the set drying ratio. Decrease according to the difference with the rate of dryness. On the other hand, if the currently calculated dry reduction rate is smaller than the set dry reduction rate, the dry reduction control unit 95 determines that drying is not progressing, and the output of the burner output from the drying unit 64 is currently set as the calculated dry reduction rate. Increase according to the difference with the reduction rate. The dry reduction control unit 95 may perform the dry reduction control using the dry reduction rate (past calculated dry reduction rate) obtained in the past, instead of the set dry reduction rate described above. In this case, the above-mentioned "set dry reduction rate" may be read as "past calculated dry reduction rate".

The first controller 80 </ b> A includes an unevenness removal control unit 96 that performs “non-uniformity removal control”. The unevenness removal control unit 96 is configured of a program stored in the first controller 80A, an electronic / electrical circuit, and the like.
The unevenness removal control unit 96 controls the drying unit 64 based on the water unevenness calculated by the water unevenness calculation unit 91. The unevenness removal control unit 96 performs control to reduce the water unevenness when the water unevenness (current water unevenness) obtained by the water unevenness calculation unit 91 is larger than a predetermined value (water unevenness setting value). Specifically, when the water unevenness is currently larger than the water unevenness setting value, the unevenness removal control unit 96 stops the output of the burner of the drying unit 64 while the drive motor of the horizontal feed mechanism 65A and the vertical feed mechanism 65B. Are driven to circulate the grain in the dryer 61A (the reservoir 63, the drying unit 64, the circulation unit 65). That is, the unevenness removal control unit 96 reduces the temperature of the grain by circulating the grain in the dryer 61A, thereby reducing the variation in the temperature of the grain. The unevenness removal control unit 96 may perform the unevenness removal control by circulating the grain while driving the ventilation device that ventilates the dryer 61A (first main body 67). Thus, by lowering the temperature and the like of the grain while circulating the grain, it is possible to reduce the moisture unevenness at the time of drying.

The heat-releasing tank 61B is a tank that cools by storing the grains dried by the drier 61A for a predetermined time. The huller 61C is a device for hulling grains that have been allowed to cool in the cold storage tank 61B.
The color separator 61D is a device that performs color inspection and color selection of grains and the like after hulling. The color selector 61D includes a hopper 61D1, an imaging unit 61D2, an injector 61D3, and a control unit (second controller) 80D. The hopper 61D1 is a member for containing grains and dropping the grains. The imaging unit 61D2 is an apparatus for capturing an image of falling grains, and the injector 61D3 sorts out grains that are determined to be defective based on the color selection result.

  The second controller 80D is a device that controls the color selector 61D, and determines, for example, whether or not the color of the grain is defective from the image of the grain imaged by the imaging unit 61D2. That is, the second controller 80D detects stink bug-damaged rice and colored rice based on the color of the imaged grain image, and determines that the grain corresponding to these is defective. When it is determined that the grain is defective, the second controller 80D outputs a command to blow off the defective grain to the injector 61D3. Therefore, according to the color separator 61D, by placing the grains in the hopper 61D1, the grains are imaged, and the colors of the grains are sorted based on the imaged images, and the inferior grains and the good grains are separated. can do.

The measuring unit 61E3 is a device that measures the weight of the grain placed in the housing member. The third controller 80E is a device that controls the weighing device 61E, and performs processing regarding measurement results, measurement start, measurement end, and the like.

  As shown in FIG. 11, between the dryer 61A, the cold storage tank 61B, the hulling machine 61C, the color separator 61D, and the weighing device 61E, a conveying device 98 configured by a belt conveyor or the like is provided. Apparatus 98 allows the grain to be transported from upstream to downstream. In addition, the conveyance apparatus 98 may be provided in a part between dryer 61A, the cold-storage tank 61B, the hulling machine 61C, the color separator 61D, and the weighing device 61E.

The crop management system includes a crop management computer (support device) 100 configured of a computer such as a server.
The crop management computer 100, the first controller 80A of the dryer 61A, the second controller 80D of the color selector 61D, and the third controller 80E of the weighing instrument 61E are connected by a network such as a LAN.

The crop management computer 100 includes an operation acquisition unit 101. The operation acquisition unit 101 is configured of a program stored in the crop management computer 100, an electronic / electrical circuit, and the like.
The operation acquisition unit 101 acquires operation information of a plurality of operating devices and machines (sometimes referred to as an operating unit) provided in the grain processing facility 60. The operation information is various information related to the operation when the operation unit is operated. The operation information includes an operation state indicating an operation state, a start time indicating an operation start time, an end time indicating an operation end time, and an operation time indicating an operation time length. In addition. The unit of time is hour, minute, time, etc. and is not limited.

In this embodiment, each of the dryer 61A, the heat radiation tank 61B, the huller 61C, the color separator 61D, and the weighing device 61E can be said to be an operating unit.
For example, the operation acquisition unit 101 acquires the operation state (during drying, stop, etc.), the drying start time, the drying end time, the drying amount, etc. from the first controller 80A etc. as the operation information of the dryer 61A which is the operating unit. . Further, the operation acquisition unit 101 uses the operation state (during color selection, cancellation, etc.), color selection result, color selection start time, color selection end time, etc. as a second controller as operation information of the color selector 61D which is the operation unit. Acquired from 80D etc. Furthermore, the operation acquisition unit 101 acquires, as operation information of the weighing unit 61E that is the operation unit, the shipment amount, the number of bags, the amount of bagging, the measurement start time, the measurement end time, and the like from the third controller 80E and the like.

Thus, the operation acquisition unit 101 of the crop management computer 100 can acquire operation information of a plurality of operation units.
Now, in the crop management system, when focusing on a plurality of operating parts, the operating information of the operating part (upstream operating part) located upstream of the predetermined operating part and the operating part (downstream operating part) located downstream The system is capable of obtaining a cumulative operation time of a predetermined operating unit based on the operation information of In this embodiment, the heat sink tank 61B and the scaler 61C are predetermined operation units, the dryer 61A is an upstream operation unit, and the color separator 61D is a downstream operation unit.

Next, an example in which the cumulative operation time of the heat-releasing tank 61B and the huller 61C is determined based on the operation information of the upstream operation unit (dryer 61A) and the downstream operation unit (color separator 61D) will be described in detail.
The crop management computer 100 includes an operation calculation unit 102. The operation calculation unit 102 is configured of a program stored in the crop management computer 100, an electronic circuit, and the like.

The operation calculation unit 102 calculates the cumulative operation time of the heat radiation tank 61B and the huller 61C based on the operation information of the dryer 61A acquired by the operation acquisition unit 101 and the operation information of the color selector 61D.
Specifically, the operation calculating unit 102 generates the heat release tank 61B and the cooling tank 61B based on the operation start time obtained from the operation information of the color selector 61D and the operation end time obtained from the operation information of the dryer 61A. The operating time in the huller 61C is determined. For example, when the operation start time (time) of the color selector 61D is 13:00 and the operation end time (time) of the dryer 61A is 11:00, the operation calculation unit 102 operates the color selector 61D. By subtracting the operation end time of the dryer 61A from the start time, "120 minutes" which is the time from the end of the operation of the dryer 61A to the start of the operation of the color selector 61D (referred to as processing elapsed time) is determined. .

  Here, between the end of the drying process of the dryer 61A and the start of the color separation process in the color separator 61D (120 minutes), the processes in the heat radiation tank 61B and the huller 61C are performed. Therefore, it may be considered that the processing elapsed time from the end of the operation of the dryer 61A to the start of the operation of the color separator 61D is the operation time at which the cold storage tank 61B and the huller 61C have operated. The operation calculation unit 102 sets the processing elapsed time as the operation time of the heat radiation tank 61B and the huller 61C.

Then, every time the end of the drying process and the start of the color selection process are repeated, the operation calculation unit 102 uses the operation end time of the dryer 61A and the operation start time of the color selector 61D The operating time (processing elapsed time) in the sliders 61C is determined, and the accumulated operating times are calculated to determine the accumulated operating times of the heat radiation tank 61B and the hullers 61C.
Therefore, the relationship between the operation end time of the dryer 61A, the operation start time of the color separator 61D, the operation time (process elapsed time) in the cold storage tank 61B and the huller 61C, and the cumulative operation time is shown in FIG. It will be. The accumulated operating time determined by the operation calculation unit 102 is stored in the storage unit 103 configured of a non-volatile memory or the like provided in the crop management computer 100 in association with the unique identification information for identifying the operation unit. Can.

  According to this, even in the case where the heat sink tank 61B and the huller 61C do not have a timer or the like for counting the cumulative operation time, the operation information of the dryer 61A, which is the upstream operation unit, and the downstream operation unit Based on the operation information of the color separator 61D, the cumulative operation time of the heat-releasing tank 61B and the huller 61C can be obtained. And since the cumulative operation time of the cold radiation tank 61B and the huller 61C is stored in the storage unit 103, the display unit in which the list shown in FIG. 19 is connected to the crop management computer 100 or the crop management computer 100 Can be displayed on an externally connected device.

  The operation calculation unit 102 may correct the operation time of the heat sink tank 61B and the operation time of the huller 61C using the standard processing time of the heat sink tank 61B and the standard treatment time of the huller 61C. . The operation calculation unit 102 determines, for example, the operation time (minutes) of the cold storage tank 61B by “operation time (minutes) = process elapsed time (minutes) −standard treatment time of the huller (minutes)”. The operating time of the machine 61C is determined by "operating time (minutes) = processing elapsed time (minutes)-standard processing time of the cooling tank (minutes)". The standard processing time of the cold radiation tank 61B may be calculated based on the past results, and the standard processing time of the huller 61C may also be calculated based on the past results.

  In the embodiment described above, a plurality of (two) operation units (heat release tank 61B and huller) sandwiched between the upstream operation unit (dryer 61A) and the downstream operation unit (color separator 61D) 61C) cumulative operation time is being sought. Instead of this, it is also possible to obtain the cumulative operation time of a single (one) operating unit sandwiched between the upstream operating unit and the downstream operating unit. FIG. 20 shows an overall view of a grain processing facility 60 according to a modification in which the cumulative operation time of one operating unit is obtained by the operation calculation unit 102.

The huller 61C includes a fourth controller 80C. The fourth controller 80C is connected to the crop management computer 100 by a network such as a LAN. The operation acquisition unit 101 of the crop management computer 100 acquires an operation state (during hulling and stopping), hulling start time, hulling end time, hulling weight and the like as the operating information of the huller 61C.
The operation calculation unit 102 subtracts the operation end time of the drier 61A from the operation start time of the crusher 61C, so that the time from the end of the operation of the drier 61A to the start of the operation of the huller 61C (processing The elapsed time is determined, and the processing elapsed time is taken as the operation time of the cooling tank 61B. The operation calculation unit 102 obtains the accumulated operation time by accumulating the operation time of the heat radiation tank 61B.

In the above-described embodiment, the accumulated operation information of the heat sink tank 61B and the huller 61C is obtained by using the predetermined operating part as the heat sink tank 61B and the huller 61C. It is not limited to 61B or hulling machine 61C.
Now, in a crop management system, it is possible to acquire various information in a production management system. Specifically, the crop management computer 100 has a production information acquisition unit 105 that acquires production information. The production information acquisition unit 105 is configured of a program stored in the crop management computer 100, an electronic / electrical circuit, and the like.

The production information acquisition unit 105 is connected to the production management computer 33C as needed to acquire the above-mentioned production information (producer information, work information, crop information). For example, after being connected to the production management computer 33C, the production information acquisition unit 105 refers to the management information storage unit 47 or the harvest information storage unit 48 to acquire work information including agricultural results, crop information, and the like.
The information obtained by the production information obtaining unit 105 is used for the drying plan and the like. Next, the drying plan will be described in detail.

  As shown in FIG. 11, the crop management computer 100 has a plan creating unit 104 that performs a drying plan. The plan creating unit 104 is composed of a program stored in the crop management computer 100, an electronic / electrical circuit, and the like. A drying plan is a plan on drying of harvested grains, and is a plan showing at least the allocation of grains to be dried and dryers. The drying plan is roughly divided into "yearly drying plan" which assigns grains to be dried and dryers throughout the year, and "day drying plan" which assigns grains to dry every day and dryers. Can.

Next, the annual drying plan will be described.
When an external connected device logs in to the crop management computer 100 and there is a request for creation of the annual drying plan from the connected device, the plan creating unit 104 responds to this request to create a screen for annual drying plan (annual drying Display the planning screen on the connected device. The connection device is the communication terminal 33A or the administrator computer 33B.

As shown in FIG. 21, the plan creation unit 104 displays the annual drying plan screen Q8 (referred to as a second screen) on the connected device. The second screen Q8 includes a cropping display unit 121, an assortment display unit 122, a field display unit 123, a harvest display unit 124, a start display unit 125, an end display unit 126, and a schedule display unit 127.
The planting display unit 121 displays the name of the planting plan. Specifically, the crop management computer 100 (plan making unit 104) is connected to the production management computer 33C, and acquires the name of the cropping plan by referring to the cropping plan storage unit 41 after the connection. The plan creation unit 104 displays the acquired cropping plan on the cropping display unit 121.

The sorting display unit 122 displays a sorting category of “pool” or “individual”. The “pool” in the sorting section is, for example, a form used by a plurality of farmers for a given dryer 61A, and “individual” means a single (dedicated) for the given dryer 61. It is the form used by farmers.
The field display unit 123 displays the number of fields corresponding to the planting plan. Specifically, the crop management computer 100 (plan making unit 104) is connected to the production management computer 33C, and acquires the number of fields corresponding to the cropping plan by referring to the cropping plan storage unit 41 after the connection. The plan creating unit 104 displays the acquired field number on the field display unit 123.

The harvest display unit 124 displays the predicted (predicted) harvest amount (total planned yield) of the whole field indicated in the cropping plan. Acquisition of the planned harvest amount is performed by the harvest amount acquisition unit 109 provided in the crop management computer 100. The harvest amount acquisition unit 109 includes a program stored in the crop management computer 100, an electronic / electrical circuit, and the like.
The harvest amount acquisition unit 109 acquires, for example, the number of fields indicated in the cropping plan and the area of each field from the production management computer 33C. Then, the harvest amount acquisition unit 109 obtains the total cropping area (total crop area) from the number of the acquired farmland and the area of each farmland, determines the total planned crop amount based on the total crop area, and displays it on the crop display unit 124 Do.

  In addition, instead of calculating the total planned harvest amount from the total field area, the harvest amount acquiring unit 109 acquires the planned yield of each field input to the crop management computer 100 or the connected device, The total planned yield may be calculated by summing the harvested amounts, or the planned yield may be calculated by other methods. Alternatively, the total planned harvest amount may be input directly to the harvest display unit 124.

The start display unit 125 displays a date (drying start date) predicted to be the earliest to dry out of grains to be harvested. The end display unit 126 displays the date of the latest drying (date of drying end) among the grains to be harvested.
The date display unit 127 displays each date and the number of dryers 61A predetermined corresponding to the date. The number of dryers 61A corresponding to the date displayed on the schedule display unit 127 can be directly input to the date display unit 127 of the second screen Q8 using an input interface or the like of a connected device.

  When the drying capacity per dryer is the same, the total amount of drying per day can be set by increasing or decreasing the number of dryers in the schedule display unit 127. In the schedule display unit 127, if the total drying amount is smaller than the planned harvest amount (total planned yield) on a predetermined date (total planned yield> total dry amount), the drying process of the grain may not be completed. . In this case, the schedule display unit 127 displays that there is a possibility that the drying process of the grain can not be completed (for example, a portion indicating the number of the dryers 61A turns red or blinks).

The above-mentioned drying start date is set based on the drying time (for example, the date to dry) calculated by the crop management computer 100. The total planned harvest amount on a predetermined date is also set based on the harvest amount to be harvested at the same drying time by first calculating the drying time.
The calculation of the drying time in the crop management computer 100 will be described.
The crop management computer 100 has a time storage unit 106, a time acquisition unit 107, and a prediction unit 108. The time storage unit 108 is configured of a hard disk or a non-volatile memory or the like. The time acquisition unit 107 and the prediction unit 108 are configured of a program stored in the crop management computer 100, an electronic / electrical circuit, and the like.

  The time storage unit 106 stores a first growth time until a grain grows from a predetermined farming operation (a first growth time until the grain grows to a harvestable level after a predetermined farming work). As illustrated in FIG. 22, the time storage unit 106 stores therein items indicating farming (cultivation, sowing, sowing, rice planting, scraping) and the first growth time. In addition, since 1st growing time may change with kind (brand) * area etc., 1st growing time corresponding to farming can be changed. The change of the first growth time can be performed by the input interface of the crop management computer 100 or by connecting the connected device to the crop management computer 100 and instructing the crop management computer 100 from the connected device.

The time acquisition unit 107 refers to the time storage unit 106 and acquires the first growth time stored in the time storage unit 106.
The prediction unit 108 performs calculation to predict the drying time to dry the grain based on the agricultural work included in the agricultural results acquired by the production information acquisition unit 105 and the first growth time acquired by the time acquisition unit 106.

  The process of the prediction unit 108 will be described using FIG. First, the prediction unit 108 is connected to the production management computer 33C to refer to the agricultural results corresponding to the cropping plan. For example, as shown in FIG. 23, when referring to the agricultural results corresponding to the planting plan of "Hihikari", the prediction unit 108 copes with "thinning" when predetermined farming work has progressed to "thinning". The first growing time to be extracted is extracted from the time acquisition unit 106, and the date (9) is obtained by adding “140 days” which is the first growing time corresponding to / 20) is the drying time.

  Alternatively, as shown in FIG. 23, when referring to the agricultural results corresponding to the planting plan of "Koshii Buki", when the predetermined agricultural work has progressed to "rice planting", the first growth time corresponding to "rice planting" The date (10/1) obtained by adding "125 days", which is the first growth time corresponding to "rice planting", and "5/29", which is the implementation date for rice planting, extracted from the time acquisition unit 106 is the drying time I assume.

In addition, when the agricultural results corresponding to the same cropping plan are referred to, the drying time determined using the farming operation with the earliest implementation date among the same farming work becomes the "drying start date" shown in the start display unit 125 .
As described above, the prediction unit 108 can easily predict the drying time based on the implementation date of the predetermined farming operation indicated by the agricultural results and the first growth time corresponding to the farming operation.

Next, the relationship between the drying time, the total planned yield of the drying time, and the number of dryers will be described with reference to FIG.
FIG. 24 shows an example of an agricultural result corresponding to a predetermined cropping plan.
As shown in FIG. 24, the prediction unit 108 extracts the fields of the same farming operation and the same implementation date in the agricultural results corresponding to the same cropping plan (for example, Koshinobuki). The prediction unit 108 extracts, for example, the A farm, the C farm, and the E farm when the farming operation is “rice planting” and the implementation date is “5/30”. Then, the total planned harvest amount (for example, 120 stones) for the A farm, C farm, and E farm is acquired from the yield acquisition unit 109.

  Here, in order to obtain the total planned yield, the harvest amount acquiring unit 109 sums the areas of the fields of A farm, C farm and E farm, and acquires the total planned harvest from the total field area. In addition, instead of calculating the total planned harvest amount from the total field area, the harvest amount acquisition unit 109 calculates the planned harvest amount of the A field, C field, and E field input to the crop management computer 100 or the connection device. May be calculated, and the total planned yield may be calculated by summing the planned yields, or the total planned yield may be calculated by other methods.

  Next, the prediction unit 108 extracts the first growth time corresponding to the same farming work from the time acquisition unit 106, and “125 days” which is the first growth time corresponding to “rice planting”, with the implementation date of rice planting By adding "5/30", the drying time "10/2" is obtained. The prediction unit 108 associates “10/2”, which is the obtained drying time, with the total planned harvest amount (for example, 120 stones) for the A farm, C farm, and E farm acquired from the yield acquisition unit 109. Then, calculation is performed to predict the total planned yield of dry season.

In this manner, the prediction unit 108 obtains the drying time from the implementation date of the same farming operation and the first growth period corresponding to the farming operation. Then, the prediction unit 108 can predict the drying time and the planned harvest amount corresponding to the drying time by correlating the drying time with the total planned harvest amount in the common field in which the same farming operation is performed.
As shown in FIG. 21, for example, in the schedule display unit 127 corresponding to the planting plan of a fine bush, the number of dryers is 1/10/2 and the total drying amount of 10/2 is “70 stones”. It is assumed that On the other hand, since the total planned yield of 10/2 is 120 stones as described above, the total planned yield> total dry amount. In this case, the number of 10/2 dryer 61A in the schedule display unit 127 is red. From this, it can be seen that the number of dryers allocated to 10/2 is small according to the annual drying plan screen Q8. In this case, the total drying amount is increased by setting the number of dryers assigned to 10/2 of the date display unit 127 to, for example, two units by the operation of the connected device etc., and the total drying amount of 10/2 is 10/20. It can be larger than the total planned yield of 2.

As described above, the annual drying plan input to the annual drying plan screen Q8 is stored in the drying plan storage unit 119 of the crop management computer 100.
In the embodiment described above, a predetermined farming operation is extracted from among the agricultural results, and the drying time is predicted based on the first growth time from the farming operation to the growth of the grain, but instead of the farming operation, The drying time may be predicted based on the actual growing condition of the grain from the growing time until harvest (second growing time). Next, a modification of the prediction of the drying time using the growing condition will be described.

  As shown in FIG. 1, the communication terminal 33A includes a growth acquisition unit 38 that acquires a growth state. When a predetermined operation is performed by the communication terminal 33A, the growth acquisition unit 38 is activated, and a growth screen Q12 as shown in FIG. 25 is displayed. The growth screen Q12 has, for example, a field input unit 34a for inputting a field, and a growth input unit 34b for inputting a growth state. In the growth input unit 34b, it is possible to input the date when the growth status was investigated (the survey date), the length of rice, the presence or absence of heading, etc. as the growth status of grains such as rice.

The growth acquisition unit 38 acquires, as a growth condition, information (such as survey date, length of rice, presence or absence of heading) input to the field input unit 34a and the growth input unit 34b of the growth screen Q12. Communication terminal 33A transmits the field and growth condition which growth acquisition part 38 acquired as an agricultural result.
The time memory unit 106 is configured to grow the second crop until the crop can be harvested from the predetermined growth condition.
The growth time is memorized. As shown in FIG. 26, the time storage unit 106 stores the period from harvesting to the harvest, the period until harvesting according to the length of the rice, and the like. In addition, since 2nd growth time may also change with kinds (brand) * area etc., 2nd growth time is changeable. The change of the second growth time can be performed by the input interface of the crop management computer 100 or by connecting the connected device to the crop management computer 100 and instructing the crop management computer 100 from the connected device.

The time acquisition unit 107 refers to the time storage unit 106 to acquire the second growth time stored in the time storage unit 106.
First, the prediction unit 108 is connected to the production management computer 33C to refer to the agricultural results corresponding to the cropping plan. Then, the prediction unit 108 extracts the growth situation in a predetermined field from the agricultural results, and acquires the second growth time corresponding to the growth situation from the time storage unit 106. The prediction unit 108 sets a date obtained by adding the second growth period to the survey date of the growth state as the drying time.

Next, the daily drying plan will be described.
When an external connected device logs in to the crop management computer 100 and there is a request for creation of a day drying plan from the connected device, the plan creating unit 104 displays a screen for setting up a day drying plan (day Display the planning screen on the connected device. The connection device is the communication terminal 33A or the administrator computer 33B.

As shown in FIG. 27, the plan creation unit 104 displays a sun drying plan screen Q9 (referred to as a third screen) on the connected device. The third screen Q9 includes a date display unit 130, a map display unit 131, and a dryer display unit 132.
The date display unit 130 displays the date for setting the daily drying plan. The date displayed on the date display unit 130 can be changed by the input interface of the crop management computer 100 or the input interface of the connected device.

  The map display unit 131 displays a map including a field. Specifically, the crop management computer 100 (plan making unit 104) is connected to the production management computer 33C, and refers to the location of the farmland where the producer can crop, etc. Display In addition, you may register the position of the field which a producer can plant in the crop management computer 100 beforehand. Also, a farmer's plantable farmland is a farmer's owned farmland or a farmer's farmland borrowed from other owners for planting.

  The dryer display unit 132 displays a dryer. The plan creating unit 104 displays a graphic showing the dryer registered in advance in the crop management computer 100. The registration of the dryer with the crop management computer 100 is performed by the crop management computer 100 or a connection device. As shown in FIG. 28, the dryer setting screen Q11 is displayed on the crop management computer 100 or the connection device, and, for example, the names of dryers that the producer can use for "pool" or "individual", etc. Correspond with the drying capacity of the dryer. The name of the dryer and the like and the drying capacity of the dryer are stored in the crop management computer 100 and the connection device.

  For example, when three dryers (drier A, dryer B and dryer C) are registered in the crop management computer 100, the dryer display portion 132 displays the dryer A, dryer B and dryer C. Is displayed as a rectangular figure G. The sizes (areas or heights) of the squares (graphics) of the dryer A, the dryer B, and the dryer C are set in accordance with the drying capacity of each dryer. In the quadrangle indicating each drier (drier A, drier B, drier C), the vertical side indicates the size of the processing capacity of the drier, and the maximum drying capacity of each drier is a numerical value in the vertical side. And so on.

  Here, as shown in FIG. 27, when “field A” is selected among the plurality of fields displayed on the map display unit 131 with the specification tool (for example, the cursor) 135 displayed on the third screen Q9, The selected "field A" is held. When the figure G of "dryer A" is selected among the plurality of dryers displayed in the dryer display portion 132, the selected "dryer A" is held and "field A" and "dryer A" And are associated. Then, on the figure G of the “dryer A”, the expected harvest amount “30 stones” of the “field A” designated by the designation tool 135 is replaced with the dry amount “30 stones” of the “dryer A”, The dry amount is indicated by the level.

In this manner, by selecting an arbitrary field displayed on the map display unit 131 and the figure G of the dryer displayed on the dryer display unit 132, the field, the expected yield of the field, the field of the field It can be associated with a dryer for drying the harvested grain.
The crop management computer 100 associates the field, the expected harvest amount of the field, and the dryer for drying the harvested grains of the field. The crop management computer 100 includes a designation unit 111, a drying setting unit 112, and a determination unit 113. The designation unit 111, the drying setting unit 112, and the determination unit 113 are composed of a program stored in the crop management computer 100, an electronic / electrical circuit, and the like.

The designation unit 111 is for designating (selecting) the field and the dryer, and displays a designating tool 135 for designating on the third screen Q9. The designation unit 111 associates an arbitrary field of the map display unit 131 designated by the designation tool 135 with an optional dryer of the designated dryer display unit 132.
When a field is designated by the designation unit 111, the harvest amount acquisition unit 109 obtains a planned harvest amount of the designated field. The drying setting unit 112 sets the harvest amount (planned harvest amount) corresponding to the field designated by the designation unit 111 to the drying amount of the dryer designated by the designation unit 111. The drying setting unit 112 sets “30 stones”, which is the planned yield of the field A, to the drying amount (30 stones) of the dryer A. At this time, as shown in FIG. 29, “30 stones” which is the drying amount of the dryer A is displayed by the level on the figure G of the dryer A of the dryer display portion 132.

  Subsequently, when the field C is selected and the dryer A is selected, the drying setting unit 112 sets “30 stone”, which is the drying amount corresponding to the planned yield of the field A already selected, The dry amount “40 stones” corresponding to the planned yield of C is set to the dry amount (70 stones) in the dryer A of 10/2. As shown in FIG. 29, in the figure G of the dryer A, the dry amount (40 stones) for drying the grains of the field C is displayed by being stacked on the dry amount (30 stones) of the dryer A.

  Then, it is assumed that the determination button displayed on the third screen Q9 is selected by the specification tool 135 and the intention to end the 10/2 sun drying plan is indicated. Here, the determination unit 113 compares the drying amount (70 stones) of the dryer A set by the drying setting unit 112 with the drying capacity (70 stones) of the designated dryer A. In this case, the drying amount of the dryer A is 70 stones and does not exceed 70 stones which is the drying capacity of the dryer A. Therefore, the determination unit 113 determines that the drying amount of the dryer set by the drying setting unit 112 does not exceed the designated drying ability of the dryer, so that the grains and the dryer of the field A and the field C are displayed in 10/2. Allow determination of the drying plan to assign A and. The drying plan permitted by the determination unit 113 is stored in the drying plan storage unit 119 of the crop management computer 100.

On the other hand, when the field A, the field C, the field E and the dryer A are selected, the drying setting unit 112 sets “30 stones”, which is the drying amount corresponding to the expected harvest amount of the field A, and the expected harvest of the field C The drying amount corresponding to the amount “40 stones” and the drying amount corresponding to the expected harvest amount of the field E “50 stones” to the drying amount (120 stones) in the dryer A for 10/2 Set
In this case, the drying amount of the dryer A is 120 stones, which exceeds 70 stones which is the drying capacity of the dryer A. Therefore, since the determination unit 113 determines that the drying amount of the dryer set by the drying setting unit 112 exceeds the drying ability of the designated dryer, the cereal of Field A, Field C, and Field E is displayed on 10/2. It is judged that it is impossible to decide the drying plan to which the drier A and the dryer A are to be allocated, and the review of the drying plan is displayed on the third screen Q9.

As mentioned above, in the daily drying plan, when the plan more than the drying capacity of the drier is done, it is possible to easily review the drying plan.
In crop management system, it is possible to review the drying plan from the agricultural results in addition to making the drying plan.
As illustrated in FIG. 11, the crop management computer 100 includes a first condition acquisition unit 114, a second condition acquisition unit 115, a plan acquisition unit 116, a determination unit 117, and a notification unit 118. The first condition acquisition unit 114, the second condition acquisition unit 115, the plan acquisition unit 116, the determination unit 117, and the notification unit 118 are configured from programs stored in the crop management computer 100, electronic and electrical circuits, and the like.

The first situation acquisition unit 114 is for acquiring the harvest situation of grain. The first situation acquisition unit 114 is connected to, for example, the production management computer 33C, refers to the management information storage unit 47, and displays the field, harvest date, harvest amount, moisture amount at harvest indicated in the agricultural results, Acquired as a harvest situation.
The 2nd condition acquisition part 115 acquires the drying condition of the dryer which dries a grain. The second condition acquisition unit 115 is connected to, for example, the first controller 80A or the operation acquisition unit 101, and the operation state (during drying, stop, etc.) of the dryer 61A, the drying start time, the drying end time, the dry amount Acquire the moisture during drying, the rate of dryness, the target moisture content, etc. as the drying condition.

The plan acquisition unit 116 acquires the daily drying plan, and refers to the drying plan storage unit 119 to acquire the correspondence between the designated dryer and the designated field on a predetermined date.
The determination unit 117 determines whether it is necessary to change the drying plan based on the drying plan, the harvest status, and the drying status.
The determination of the determination unit 117 will be described using FIG.

  As shown in FIG. 30, according to the drying condition acquired by the second condition acquiring unit 115, the drying start time of the dryer A is 22:00 and the drying amount of the dryer A is 70 stones at the time of 10/1. It is assumed that the amount of water during drying is 23%, the rate of dryness is 0.5% / h (per hour), and the target amount of water is 15%. In addition, according to the harvest status acquired by the first status section 115, it is assumed that the harvest amount of the field A is 35 stones and the harvest amount of the field C is 35 stones at 9:00 of 10/2. According to the 10/2 daily drying plan acquired by the plan acquisition unit 116, it is assumed that the plan for drying the grain corresponding to the field A and the grain corresponding to the field C to the dryer A is planned.

Judgment part 117 is 10/1 of the previous day whether it is possible to allocate the grain shown in the harvest situation of 10/2 to the predetermined dryer (dryer A) shown in the drying plan. Judging from the dry condition of
For example, the determination unit 117 calculates the drying end time predicted from the drying condition of the dryer A. Here, since the drying start time is 22:00, the dryness reduction rate is 0.5% / h, and the target moisture content is 15%, the judgment unit 117 estimates that the expected drying end time is 10/2. It is predicted as: 00.

  The judgment part 117 judges what the crop condition is at 14:00 on 10/2 which is the drying end time of the dryer A. Specifically, the judgment unit 117 refers to the harvest situation acquired by the first situation unit 115 and already plans to dry the dryer A at 9:00, which is before 14:00 on 10/2. It is judged that the grain (harvest 35 stone of field A, harvest 35 stone of field C) is harvested. In this case, in 10/2, the determination unit 117 ends the harvest of the grain to be dried by the dryer A (the harvest of the grain in the field A and the field C) before the drying end time of the dryer A. Since it will not be possible to dry the grains of the field A and the field C if the drying of the dryer A is not completed, it is judged that the allocation of the grains shown in the 10/2 harvest situation can not be made.

  In addition, since a certain amount of time may pass after the harvest of the grain, in the determination, if it is a situation where the dryer can be inserted within a predetermined time (within several hours) after the harvest, the determination unit 117 May be determined to be assignable. In this case, it is desirable that the allowable time (allowable time) from the harvest of the grain to the start of the drying is set in advance in the crop management computer 100 (determination unit 117).

  The notification unit 118 notifies the crop management computer 100C or the connected device when it is necessary to change the drying plan. That is, when the determination unit 117 can not allocate the grain according to the drying plan, the notifying unit 118 notifies the connected device or the like that the allocation can not be performed according to the drying plan. For example, at the end of the 10/2 harvest, the notification unit 118 notifies the communication terminal 33A, which is a connected device, and the administrator computer 33B that the drying of the dryer A is not completed. In this way, a worker who holds the communication terminal 33A or a manager of the manager computer 33B can arrange a new drying destination.

Next, another determination of the determination unit 117 will be described using FIG.
As shown in FIG. 31, according to the harvest situation acquired by the first situation unit 115, the moisture content at harvest time of the field A is 23%, the moisture content at harvest time of the field C is 29%, the field A and the field C The end of harvest time is assumed to be 12:00 on 10/2. In this case, since the harvest end time and the drying end time are the same, the determination unit 117 determines that the allocation according to the drying plan can be performed at the harvest end time and the drying end time. In addition, the determination unit 117 determines whether it is possible to allocate the cereals indicated in the 10/2 harvest condition, not from the 10/2 dry condition, but from the harvest condition.

  The determination unit 117 refers to the drying plan, and 10/2 grasps that the grains of the field A and the grains of the field C are dried for a predetermined drier (drier A). The determination unit 117 compares the amount of water at the time of harvesting of the field A with the amount of water at the time of harvesting of the field C, with reference to the harvesting situation. The water content at the time of harvest of the field A is 23%, the water content of the field C is 29%, and the difference in the water content is 5% or more. Because the difference between the moisture content of the two grains in the same dryer A is 5% (greater than the judgment standard) and large, the judgment unit 117 can not allocate the grains indicated in the 10/2 harvest situation. I will judge.

Also in this case, the notification unit 118 has a large difference between the water content of the field A and the water content of the field C at the end of the 10/2 harvest, and it is difficult to plug in the same dryer. Notice.
Next, another determination of the determination unit 117 will be described with reference to FIG.
As shown in FIG. 32, according to the harvest situation acquired by the first situation unit 115, the harvest operation of the field A is not performed at 14:00 of 10/2, that is, the harvest operation of the field A is performed. It is assumed that there is no agricultural record to be carried out, and the harvest of field C has been completed. According to the drying condition acquired by the second condition unit 116, it is assumed that the drying of the dryer A is finished at 14:00 of 10/2.

  The determination unit 117 refers to the drying plan, and 10/2 grasps that the grains of the field A and the grains of the field C are dried for a predetermined drier (drier A), and the drying is performed. Refer to the situation and harvest situation. The determination section 117 determines that the blank operation in which the dryer A is not drying occurs because the harvesting operation of the field A is not performed when the drying of the dryer 2 of 10/2 is finished. Also in this case, the determination unit 117 determines that allocation is not possible.

  The notification unit 118 notifies the connected device that the harvest of the grain entrained in the 10/2 dryer A is slower than planned and the dryer has a blank time. In the description of FIG. 32, it is determined whether or not allocation is possible with reference to the harvest situation at the drying finish time of the dryer A, but the standard time required for harvesting and loading (standard time) In consideration of the above, the harvest situation may be referred to before the standard time, and it may be predicted whether or not the harvest and loading will be finished at the drying end time, and it may be judged whether the assignment can be made according to the prediction.

Now, it is desirable to display production information, in particular, producer information in the production information, in the above-mentioned dryer 61A. The modification which displays producer information on drier 61A is explained in detail.
When the drying process is performed by the dryer 61A, the first controller 80A of the dryer 61A is connected to the crop management computer 100 to request production information as shown in FIG. 33 (S1). The production information acquisition unit 105 of the crop management computer 100 is connected to the production management computer 33C in response to the request of the first controller 80A, and refers to the harvest information storage unit 48 (S2). Then, the production information acquisition unit 105 acquires the specific information assigned at the time of harvest and the producer information calculated from the specific information (S3: acquisition process of producer information).

Specifically, in the producer information acquisition process S3, first, the production information acquisition unit 105 harvests the storage identification information (first identification information) of the first storage member 55 and the consignment ID (receipt information) 48. Get from The first identification information and the consignment ID are identification information (first identification information) assigned at the time of harvest.
Then, the production information acquisition unit 105 further extracts, from the harvest information storage unit 48, an agricultural result associated with the receipt ID, using the obtained receipt ID as a search key. Next, the production information acquisition unit 105 refers to the management information storage unit 47 and extracts the cropping plan associated with the extracted agricultural result. Then, the producer information corresponding to the extracted planting plan is extracted from the management information storage unit 47.

After the production information acquisition unit 105 acquires the producer information, the acquired producer information is transmitted to the first controller 80A of the dryer 61A (S4). The display 68 displays producer information.
As described above, by linking the crop management computer 100 and the production management computer 33C, it is possible to display the producer of the grain processed by the dryer 61A or the like.
The display of the producer information is not limited to the dryer 61A, and may be anything as long as it is a processor provided in the grain processing facility 60, and the color selection which is one of the cold storage tank 61B, the huller 61C and the preparation machine The machine 61D may be a weighing machine 61E.

In the embodiment described above, the crop management computer 100 uses the storage identification information of the first storage member 55 and the consignment ID as the specific information to determine the producer information, but instead, the field of the harvested grain is replaced The second identification information identifying the second information may be acquired as the specific information, and the producer information may be determined based on the second identification information.
In this case, in the producer information acquisition process S3, first, the production information acquisition unit 105 refers to the harvest information storage unit 48 and extracts the agricultural record. Then, the production information acquisition unit 105 refers to the management information storage unit 47, extracts the cropping plan associated with the extracted agricultural record, and produces producer information corresponding to the extracted cropping plan from the management information storage unit 47. Extract.

When predicting the drying time, the prediction unit 108 is connected to, for example, the management information storage unit 47 and refers to the agricultural performance. In addition, the prediction unit 108 extracts the first growth time corresponding to the agricultural work shown in the agricultural results from the time acquisition unit 106, and obtains the drying time by adding the first growth time on the day of the agricultural work.

  In addition, the time memory | storage part 106 may memorize | store the 2nd growth time corresponding to a growth condition instead of the 1st growth time corresponding to farming. In this case, the prediction unit 108 is connected to the management information storage unit 47, refers to the agricultural results, extracts the growing condition in a predetermined field from the agricultural results, and the second growing time corresponding to the growing condition It is acquired from the storage unit 106. Then, the prediction unit 108 sets a date obtained by adding the second growth period to the research date of the growth state as the drying time.

In addition, it is possible to review the drying plan by the production management computer 33C. A review of the drying plan by the production management computer 33C will be described.
