Description

  The present invention relates to an agricultural chemical estimation apparatus and the like.

  Traditionally, farm workers identify the required amount of agricultural chemicals from the planted area of the target crop to which the agricultural chemical is applied, the dilution ratio of the agricultural chemical, and the amount of application per unit area, and estimate the cost of the agricultural chemical according to the required amount. Is going.

  Here, since the capacity of the agricultural chemical container for storing the agricultural chemical is stepwise such as 250 ml, 500 ml, etc., the worker can calculate the necessary amount of the agricultural chemical and then supplement the necessary amount of the agricultural chemical. Choose a combination and purchase pesticides.

JP 2003-189742 A

  However, the above-described conventional technique has a problem that it is impossible to estimate an optimal combination of agricultural chemical containers.

  At present, it is important to ensure the safety of agricultural chemicals. In addition, when estimating the purchase price of agricultural chemicals, not only simply calculating the cheapest purchasing method from the required amount of agricultural chemicals, but also considering the safety of the work of diluting the agricultural chemicals, the unit of agricultural chemical containers matches the tank capacity. It is desirable to “use up”. For example, if the tank is filled with water and all of the pesticide in the pesticide container is placed in the tank, if the pesticide with the desired dilution ratio can be created, the operation is simplified and operator errors can be prevented. .

  However, at present, it is difficult for the worker to make an estimate that the pesticide container can be used up. For this reason, we use a measuring container to measure the amount of pesticide from the pesticide container and place it in the tank. In this case, it is easy for workers to make mistakes, and the pesticide may spill out of the pesticide container and adhere to workers' clothing. There is a risk of affecting.

  In one aspect, an object is to provide an agricultural chemical estimation apparatus and an agricultural chemical estimation method capable of estimating an optimal combination of agricultural chemical containers.

  In the first plan, the agrochemical estimation apparatus includes a storage unit, a reception unit, and a determination unit. A memory | storage part stores the information of the 1st container in which the agricultural chemical before dilution was accommodated and the price was set according to the capacity | capacitance of each step. The reception unit receives information on the second container that stores the diluted pesticide and information on the dilution ratio of the pesticide. Based on the information on the first container, the information on the second container, and the information on the dilution ratio, the determination unit dilutes the pesticide contained in the first container at the dilution ratio, thereby reducing the capacity of the second container. When satisfy | filling, the pesticide accommodated in the 1st container is used up, and the combination of the capacity | capacitance of the said 1st container with a low price is determined.

  According to one embodiment of the present invention, there is an effect that an optimal combination of agricultural chemical containers can be estimated.

  Embodiments of an agricultural chemical estimation apparatus and an agricultural chemical estimation method disclosed in the present application will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is a functional block diagram showing the configuration of the agricultural chemical estimation apparatus according to the present embodiment. As illustrated in FIG. 1, the agricultural chemical estimation apparatus 100 includes a communication unit 110, an input unit 120, a display unit 130, a storage unit 140, and a control unit 150.

  The communication unit 110 is a processing unit that performs communication with an external device via a network. The communication unit 110 corresponds to a communication device.

  The input unit 120 is an input device for an operator or the like to input data to the agrochemical estimation device 100. For example, the input unit 120 corresponds to a keyboard, input keys, a touch panel, and the like. The display unit 130 is a display device that displays data output from the control unit 150 described later. The display device 130 corresponds to, for example, a display or a touch panel.

  The storage unit 140 includes pesticide application information 140a and single-use table information 140b. For example, the storage unit 140 corresponds to a semiconductor memory device such as a random access memory (RAM), a read only memory (ROM), and a flash memory, and a storage device such as a hard disk drive (HDD).

  The agricultural chemical application information 140a is a table that holds various types of information related to agricultural chemicals. FIG. 2 is a diagram illustrating an example of a data structure of pesticide application information. As shown in FIG. 2, this agrochemical application information 140a correlates agrochemical name, cropping item, applicable pest, dilution rate, amount of liquid used, number of uses, and capacity / price.

  Among these, the agrochemical name indicates the name of the agrochemical. Cropped items indicate crops that use pesticides. Applicable pests indicate pests for which the pesticide is effective. The dilution rate indicates the allowable dilution rate of the agricultural chemical. The amount of liquid used indicates an allowable amount of liquid used per 10a. The number of uses is the number of uses of pesticides allowed for the same crop. The capacity / price indicates the price of the pesticide relative to the capacity.

  For example, in the first record in FIG. 2, it is shown that the agricultural chemical name “A emulsion” is used for extermination of stink bugs that harm Chinese cabbage. The agrochemical name “A emulsion” should be used after diluting the dilution ratio to “2000 to 3000 times”, the amount of liquid used should be “100 to 300 L / 10a”, and the number of times of use should be “within 3 times”. Is defined. In addition, the agricultural chemical container with the agricultural chemical name “A emulsion” includes, for example, an agricultural chemical container in which A emulsion contains “250 ml” and an agricultural chemical container in which A emulsion contains “500 ml”. The price of a “250 ml” agricultural chemical container is “2470 yen” per bottle, and the price of a “500 ml” agricultural chemical container is “4780 yen” per bottle.

  The single-use table information 140b is a table that holds the relationship between the tank capacity and the dilution factor for using up the pesticide container. FIG. 3 is a diagram illustrating an example of a data structure of single-use table information. As shown in FIG. 3, this single use table information 140b associates tank capacity, agrochemical name, and single use information. The tank capacity indicates the capacity of the tank. The agrochemical name indicates the name of the agrochemical. Use-up information indicates information on the dilution rate for using up the agrochemical container according to the tank capacity.

  FIG. 4 is a diagram illustrating an example of a data structure of the single use information. FIG. 4 shows, as an example, use-up information corresponding to a tank capacity “1000 L” and an agrochemical name “B water solvent”. As shown in FIG. 4, this single use information associates the dilution rate with the agrochemical container combination. The dilution factor in FIG. 4 is a candidate for a dilution factor for using up the agrochemical container. Here, as an example, the candidate for the dilution rate is “1000 times, 1333 times, 2000 times”.

  When the dilution rate is set to “1000 times”, the combination of agricultural chemical containers that can be used up is any one of the following combinations (1) to (3). (1) Four “250 ml” pesticide containers. (2) One “500 ml” pesticide container and two “250 ml” pesticide containers. (3) Two “500 ml” pesticide containers.

  When the dilution rate is set to “1333 times”, the combination of agricultural chemical containers that can be used up is either of the following combinations (4) and (5). (4) Three “250 ml” pesticide containers. (5) One “500 ml” pesticide container and two “250 ml” pesticide containers.

  When the dilution factor is set to “2000 times”, the combination of agricultural chemical containers that can be used up is any one of the following combinations (6) and (7). (6) Two “250 ml” pesticide containers. (7) One “500 ml” pesticide container.

  In addition, when the dilution rate is set to “4000 times”, the combination of pesticide containers that can be used up is one “250 ml” pesticide container. However, the dilution factor “4000 times” indicates that the dilution rate of the B water solvent is not specified.

  The control unit 150 includes a reception unit 150a and a determination unit 150b. The control unit 150 corresponds to an integrated device such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA). The control unit 150 corresponds to an electronic circuit such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit).

  The accepting unit 150a is a processing unit that accepts use condition information for each cropping item from the input unit 120. The receiving unit 150a outputs the received usage condition information to the determination unit 150b. For example, the “use condition information” includes a cropping item, agrochemical name, cropping area, dilution rate, unit application amount, number of uses, tank capacity, and the like. The tank capacity includes, for example, a capacity when the tank is full and tank scale information. The scale information corresponds to, for example, information that a scale is added in units of 100 L in a tank having a capacity of 1000 L.

  Based on the information on the use conditions, the determination unit 150b uses the pesticide container in the capacity of the pesticide container that is low in price and uses up the pesticide in the pesticide container when the tank is filled with the specified dilution factor. It is a processing part to determine. The determination unit 150b outputs the determination result to the display unit 130. Hereinafter, the processing of the determination unit 150b will be specifically described.

  First, the determination unit 150b determines whether there is a combination that uses up the capacity of the agricultural chemical container based on the tank capacity, the dilution rate, and the capacity of the agricultural chemical container corresponding to the agricultural chemical name. For example, the determination unit 150b calculates the necessary amount of pesticide when the tank is full based on the formula (1).

  Necessary amount of pesticide = volume of pesticide / dilution ratio (1)

  The determination unit 150b divides the necessary amount of the agrochemical obtained by Expression (1) by each capacity of the agrochemical container, and determines that there is a combination that uses up the capacity of the agrochemical container when the divided result is a natural number. Here, the determination unit 150b identifies the agricultural chemical container corresponding to the agricultural chemical by comparing the agricultural chemical name included in the usage condition information with the agricultural chemical application information 140a.

  For example, a case where the tank capacity is “500 L”, the dilution factor is “2000”, and the agricultural chemical container corresponding to the agricultural chemical is “250 ml” will be described. In this case, when the determination unit 150b uses the formula (1), the required amount of the agricultural chemical becomes “0.25L”. Then, the determination unit 150b determines that there is a combination that uses up the capacity of the agricultural chemical container because the division result is “1” when the necessary amount of the agricultural chemical is divided by the capacity “250 ml (0.25 L)” of the agricultural chemical container. To do.

  For example, a case where the tank capacity is “500 L”, the dilution factor is “2000”, and the agricultural chemical container corresponding to the agricultural chemical is “500 ml” will be described. In this case, when the determination unit 150b uses the formula (1), the required amount of the agricultural chemical becomes “0.25L”. Then, when the determination unit 150b divides the required amount of the agrochemical by the capacity of the agricultural chemical container “500 ml (0.5 L)”, the division result becomes “0.5”, so there is a combination that uses up the capacity of the agricultural chemical container. Judge that.

  In addition, there may be a plurality of types of capacity of the agricultural chemical container corresponding to the agricultural chemical. In this case, the determination unit 150b uses the capacity of one of the agrochemical containers to divide the required amount of the agrochemical, and if there is a result in which the division result is a natural number, the capacity of the agrochemical container is determined. It is determined that there is a combination that is used up.

  The determination part 150b performs the said process, and when there exists the combination which uses up the capacity | capacitance of an agrochemical container, it performs an estimation process. The estimation process will be described later. On the other hand, when there is no combination that uses up the capacity of the agrochemical container, the determination unit 150b displays a selection screen on the display unit 130 to display “change dilution ratio”, “change tank capacity”, “ Select one of “Low”. The worker refers to the selection screen and operates the input unit 120 to select one of “change dilution ratio”, “change tank capacity”, and “lowest price”.

  Processing performed by the determination unit 150b when “change of dilution ratio” is selected will be described. When “change dilution ratio” is selected, the determination unit 150b displays candidates for dilution ratios that can use up the capacity of the agricultural chemical container, and selects one of the dilution ratios.

  For example, the determination unit 150b compares the tank capacity and pesticide name set included in the use condition information with the use-up table information 140b, and extracts the use-up information corresponding to the tank capacity and pesticide name set and extracts the information. The used-up information is displayed on the display unit 130. For example, when the tank capacity is “1000 L” and the pesticide name is “B water solvent”, the single use information shown in FIG. 4 is extracted from the single use table information 140 b and displayed on the display unit 130.

  The worker refers to the use-up information displayed on the display unit 130 and operates the input unit 120 to select any dilution factor. When any one of the displayed dilution ratios is selected, the determination unit 150b updates the dilution ratio of the use condition according to the selected dilution ratio.

  Processing performed by the determination unit 150b when “change tank capacity” is selected will be described. When “change tank capacity” is selected, the determination unit 150b receives an input of the changed tank capacity. In this case, the worker operates the input unit 120 to input the tank capacity.

  Since the tank has scales in units of 100 L and 200 L, by using these scales, it is possible to perform dilution up to each scale instead of being full. The worker refers to the scale and inputs the tank capacity. For example, if the tank capacity is “1000 L” and the tank is calibrated in units of 200 L, the worker inputs 800 L, 600 L, etc. as the tank capacity.

  When the determination unit 150b receives a new tank capacity, the determination unit 150b updates the tank capacity in the usage condition information, and uses the above equation (1) to determine whether there is a combination that uses up the capacity of the agricultural chemical container. Determine. If there is a combination that uses up the agrochemical container, the determination unit 150b performs an estimation process. On the other hand, when there is no combination that uses up the agrochemical container, the screen for receiving the input of the tank capacity is displayed again.

  In addition, the determination part 150b may perform the said process automatically, when the information regarding the tank capacity | capacitance scale is contained in the information of use conditions. For example, when “change tank capacity” is selected, the determination unit 150b determines a tank capacity candidate based on the tank capacity and the scale unit. For example, when the tank capacity is “1000 L” and the tank is calibrated in units of 200 L, the tank capacity candidates are “800 L, 600 L, 400 L, 200 L”. The determination unit 150b uses the formula (1) to determine whether there is a combination that uses up the agrochemical container for each tank capacity candidate, so that the tank capacity corresponding to the combination that is used up is determined for each tank. You may specify from capacity candidates. The determination unit 150b updates the tank capacity of the use condition with the specified tank capacity. For example, when there are a plurality of tank capacity candidates corresponding to combinations that are used up, the determination unit 150b may select the candidate having the largest tank capacity.

  Processing performed by the determination unit 150b when “lowest price” is selected will be described. When “lowest price” is selected, the determination unit 150b calculates the required amount of the agricultural chemical based on the formula (1), and becomes the lowest price among the combinations of the agricultural chemical containers that exceed this capacity. Determine the combination of pesticide containers. When the lowest price is selected, the determination unit 150b does not determine the combination of the agricultural chemical containers to be used up.

  Next, an example of the estimation process performed by the determination unit 150b will be described. The determination unit 150b calculates the total required amount of agricultural chemicals based on the information on the use conditions. For example, the determination unit 150b calculates the total pesticide requirement based on the formula (2).

  Total pesticide requirement (L) = {Agricultural area (a) / 10 (a) × Unit usage (L / 10a) / Dilution factor} × Number of uses (2)

  The determination unit 150b calculates the total number of pesticides required, and then calculates the number of tank uses and the remaining amount of pesticides using Equation (3). For equation (3), the quotient corresponds to the number of tank uses, and the remainder is the amount of remaining agricultural chemicals.

  Total amount of pesticide required / tank capacity (L) (3)

  Next, the determination unit 150b identifies the combination with the lowest price among the combinations that use up the capacity of the agricultural chemical container. Moreover, the determination part 150b specifies the amount of agricultural chemicals before dilution about the remaining amount of agricultural chemicals, and specifies the cheapest agricultural chemical container among the agricultural chemical containers which become more than the specified agricultural chemical amount. And the determination part 150b calculates the total amount and price of an agrochemical container based on the specified agrochemical container and the frequency | count of tank use. Conceptually, the total amount of the pesticide container can be expressed by equation (4). It should be noted that any conventional technique may be used as a method for calculating the lowest price combination.

  Total amount of pesticide containers = (combination that uses up the capacity of pesticide containers (lowest)) x number of tanks used + pesticide containers that are more than the amount of pesticides before dilution relative to the remaining amount of pesticides (lowest) ...

  For example, the combination (lowest price) that uses up the capacity of pesticide containers is one “500 ml” pesticide container and two “250 ml” pesticide containers. The amount of the previous agricultural chemical is “200 ml”. In this case, for example, the total amount of the pesticide containers is two “500 ml” pesticide containers, four “250 ml” pesticide containers, and one “250 ml” pesticide container corresponding to the remaining pesticide amount. .

  The determination unit 150b causes the display unit 130 to display information on the use conditions of the agrochemicals, the type and price of each agricultural chemical container, based on the calculation result. FIG. 5 is a diagram illustrating an example of a screen displayed on the display unit by the determination unit. In FIG. 5, for example, 50a indicates information on usage conditions. 50b shows the total amount of an agrochemical container. 50c shows the combination which uses up an agrochemical container about one tank. 50d shows the agrochemical container corresponding to the remainder of Formula (3). 50e indicates a price corresponding to the total amount of the agricultural chemical container. Note that the dilution factor and the tank capacity included in the information on the use conditions of 50a are appropriately updated according to the process described above.

  Hereinafter, an example of information on a plurality of use conditions and an estimation result of the determination unit 150b for each use condition will be described. FIG. 6 is a diagram illustrating a relationship between each use condition and application information. In FIG. 6, use conditions 60a, 61a, and 62a are shown as information on use conditions. Also, application information corresponding to the use conditions 60a, 61a, and 62a is referred to as application information 60b, 61b, and 62b, respectively. The application information corresponds to the agricultural chemical application information 140a shown in FIG.

  An example of an estimation result for the use condition 60a will be described. When the determination unit 150b calculates the necessary amount of agricultural chemicals when the tank is full based on the formula (1), the required amount of agricultural chemicals = 500 (L) /2000=0.25 (L). For this reason, for example, the combination that uses up the capacity of the pesticide container is “one 250 ml” pesticide container.

  When the determination unit 150b calculates the spray area for one full tank, "spread area = 500 (L) / 200 (L / 10a) = 2.5 (10a) = 25a". Moreover, if the determination part 150b calculates the required amount of agrochemicals for one cropping area, it will be "230 / 10x200 / 2000 = 2.3".

  When the determination unit 150b calculates the amount of sprayed agricultural chemical per cropping area, “sprayed agricultural chemical amount = 230 (a) / 10 (a) × 200 (L / 10a) = 4600 (L)”. When the determination unit 150b divides the amount of the sprayed agricultural chemical by the tank capacity, “4600 (L) / 500 (L) = 9 remainder 100 (L)”, and therefore the number of times the tank is used is “9 times”. The remaining 100 L corresponds to “1/5” of the tank capacity. For this reason, the amount of the agrochemical before dilution of the agrochemical at the time of the last tank use corresponds to 1/5 agrochemical container of “250 ml”.

  For this reason, the number of agricultural chemical containers of “250 ml” per use is 9 and 1/5. Accordingly, when the number of times of use is two, the number of “250 ml” pesticide containers is 18 and 2/5, and this combination is the estimation result.

  An example of an estimation result for the use condition 61a will be described. In the use condition 61a, the initial dilution rate was “1500 times”, but there was no combination that used up the capacity of the agrochemical container at this dilution rate, so it was changed to “1667 times”.

  When the determination unit 150b calculates the necessary amount of the agricultural chemical when the tank is full based on the formula (1), “the required amount of the agricultural chemical = 500 (L) /1667≈0.3 (L)”. For this reason, for example, the combination that uses up the capacity of the agricultural chemical container is “3” of the agricultural chemical container of “100 g”.

  When the determination unit 150b calculates the spraying area for one full tank, "spreading area = 400 (L) / 200 (L / 10a) = 2.5 (10a) = 25a". Further, when the determination unit 150b calculates the required amount of agricultural chemicals for one cropping area, “50 (a) / 25 (a) × 3 (book) = 6 (book)” is obtained.

  When the determination unit 150b calculates the amount of the sprayed agricultural chemical per planting area, “sprayed agricultural chemical amount = 50 (a) / 10 (a) × 200 (L / 10a) = 1000 (L)”. When the determination unit 150b divides the sprayed agricultural chemical amount by the tank capacity, it becomes “1000 (L) / 500 (L) = 2 remainder 0”, and therefore the number of times the tank is used is “2 times”.

  For this reason, the number of "100 g" pesticide containers per use is "3 x 2 = 6". Therefore, when the number of times of use is two, there are 12 “100 g” pesticide containers, and this combination is the estimation result.

  An example of an estimation result for the use condition 62b will be described. When the determination unit 150b calculates the necessary amount of agricultural chemicals when the tank is full based on the formula (1), the required amount of agricultural chemicals = 500 (L) /2000=0.25 (L). For this reason, for example, the combination that uses up the capacity of the pesticide container is “one 250 ml” pesticide container.

  When the determination unit 150b calculates the spray area for one full tank, "spread area = 500 (L) / 200 (L / 10a) = 2.5 (10a) = 25a". In addition, when the determination unit 150b calculates the required amount of the agricultural chemical for one cropping area, “110/10 × 200/2000 = 1.1” is obtained.

  When the determination unit 150b calculates the amount of sprayed agricultural chemical per cropping area, the amount of sprayed agricultural chemical is 110 (a) / 10 (a) × 200 (L / 10a) = 2200 (L). When the determination unit 150b divides the amount of the sprayed agricultural chemical by the tank capacity, “2200 (L) / 500 (L) = 4 remainder 200 (L)”, and therefore the number of times the tank is used is “4 times”. The remaining 200 L corresponds to “2/5” of the tank capacity. For this reason, the amount of pesticide before dilution of the pesticide when using the last tank corresponds to 2/5 “250 ml” pesticide containers.

  For this reason, there are 4 and 2/5 pesticide containers of “250 ml” per use. Therefore, when the number of uses is 3, the number of “250 ml” pesticide containers is 13 and 1/5, and this combination is the estimated result.

  The determination unit 150b calculates the estimation results for the use conditions 60a to 62a, and then sums the combinations of the agricultural chemical containers. For example, there are 18 and 2/5 pesticide containers whose estimated results for the use condition 60a are “250 ml”. There are 12 agrochemical containers whose estimated result for the use condition 61a is “100 g”. There are 13 and 1/5 agrochemical containers whose estimated result for the use condition 62a is "250 ml". Here, when the agricultural chemical “A emulsion” and the usage condition “C emulsion” under the use condition 60a are the same components, the determination unit 150b determines the estimation result for the use condition 60a and the estimation result for the use condition 62a. And may be totaled. Information regarding whether or not they are the same component may be input to the agrochemical estimation apparatus 100 in advance.

  For example, when the determination unit 150b sums the estimation results of the use conditions 60a and 62a, the number of agricultural chemical containers of “250 ml” is 31 and 3/5. Further, the determination unit 150b may round 3/5 into one, and each estimation result of the use conditions 60a and 62a may be 32 “250 ml” pesticide containers. If the price of the pesticide container of “250 ml” is “2470 yen” and the price of the pesticide container of “100 g” is “920 yen”, the total amount is (2470 yen × 32 + 920 × 6 = 84,560 yen) “84” , 560 yen ".

  Next, an example of the processing procedure of the agricultural chemical estimation apparatus 100 according to the present embodiment will be described. FIG. 7 is a flowchart showing a processing procedure of the agricultural chemical estimation apparatus according to the present embodiment. As shown in FIG. 7, the agrochemical estimation apparatus 100 accepts use conditions (step S101), and determines a combination that is used up (step S102).

  The agrochemical estimation apparatus 100 determines whether there is a combination that is used up (step S103). If there is a combination that is used up (Yes in step S103), the agricultural chemical estimation apparatus 100 executes an estimation process (step S104). The agricultural chemical estimation apparatus 100 determines whether there is another estimate (step S105). When there is another estimate (step S105, Yes), the agricultural chemical estimation apparatus 100 proceeds to step S101. On the other hand, when there is no other estimate (No at Step S105), the agricultural chemical estimation apparatus 100 displays the estimation result (Step S106).

  On the other hand, in step S103, the pesticide estimation apparatus 100, when there is no combination to be used up (step S103, No), causes any one of dilution ratio change, tank setting change, and lowest price to be selected (step S107).

  When the “lowest price” is selected (step S107, lowest price), the agricultural chemical estimation apparatus 100 selects the combination of the lowest agricultural chemical containers (step S108), and proceeds to step S104.

  When “tank setting change” is selected (step S107, tank setting change), the agricultural chemical estimation apparatus 100 determines the “use-up” combination due to the tank setting change. Moreover, the agricultural chemical estimation apparatus 100 displays the determination result and accepts selection of any combination (step S109).

  When the “use-up” combination is selected (step S110, Yes), the pesticide estimation apparatus 100 proceeds to step S104. On the other hand, when the “use-up” combination is not selected (No at Step S110), the pesticide estimation apparatus 100 proceeds to Step S107.

  When the “dilution factor change” is selected (step S107, dilution factor change), the pesticide estimation apparatus 100 determines the “use-up” combination by the dilution factor change. Moreover, the agricultural chemical estimation apparatus 100 displays the determination result, accepts selection of any combination (step S111), and proceeds to step S110.

  Next, the process for accepting the use conditions shown in step S101 of FIG. 7 will be specifically described. FIG. 8 is a flowchart showing a processing procedure for accepting a use condition. The agricultural chemical estimation apparatus 100 accepts selection of cropping items (step S201), accepts selection of agricultural chemicals (step S202), and accepts the cropping area (step S203).

  The agricultural chemical estimation apparatus 100 accepts the dilution rate (step S204) and accepts designation of the unit application amount (step S205). The agrochemical estimation apparatus 100 accepts designation of the number of times of use (step S206) and accepts the used tank capacity (step S207).

  Next, the effect of the agricultural chemical estimation apparatus 100 according to the present embodiment will be described. The agricultural chemical estimation apparatus 100 is the lowest agricultural chemical container among the combinations of agricultural chemical containers that can be used up with respect to the tank when receiving information on the usage conditions including the tank capacity and dilution ratio designated by the worker. The combination of is judged and displayed. For this reason, according to the agrochemical estimation apparatus 100, the optimal combination of agrochemical containers can be estimated.

  In addition, the pesticide estimation apparatus 100 according to the present embodiment uses the combination of the pesticide containers when the combination of pesticide containers that can be used up with respect to the tank capacity does not exist in the information on the use conditions designated by the worker. The existing dilution factor candidates are displayed on the display unit 130 and are selected by the user. For this reason, even when there is no combination of pesticide containers that can be used up for the dilution rate specified by the worker first, it is possible to notify the worker that there is a combination that can be used up by changing the dilution rate.

  In addition, the pesticide estimation apparatus 100 according to the present embodiment uses the combination of the pesticide containers when the combination of pesticide containers that can be used up with respect to the tank capacity does not exist in the information on the use conditions designated by the worker. Change to existing tank capacity. For this reason, even when the combination with respect to a tank capacity | capacitance (at the time of a full tank) does not exist, the combination which uses up an agrochemical container can be notified by changing a tank capacity | capacitance according to a scale.

  In addition, the agricultural chemical estimation apparatus 100 according to the present embodiment calculates the total usage amount of the agricultural chemical based on the unit spray amount of the agricultural chemical, the number of times of use, the cropping item, the cropping area, and the like. Division is performed, and the combination of agricultural chemical containers required as a whole is calculated based on the result of the division and the combination of the used agricultural chemical containers corresponding to the tank capacity. For this reason, the total usage-amount of an agrochemical can be supplemented, and the combination of the agrochemical container used up with respect to a tank capacity can be specified. For example, if the combination of tank capacity use is two 250ml pesticide containers, and spraying pesticides on a certain farmland, it is necessary to supplement the total use amount of pesticides in tank capacity x 2. As a combination, four 250 ml pesticide containers can be notified. For example, the worker uses up two pesticide containers in the first dilution operation, and uses up two pesticide containers in the second dilution operation, which facilitates the dilution operation.

  By the way, among the processes described in the present embodiment, all or a part of the processes described as being automatically performed can be manually performed, or the processes described as being performed manually can be performed. All or a part can be automatically performed by a known method. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters shown in the above-described document and drawings can be arbitrarily changed unless otherwise specified.

  Furthermore, each processing function performed by each device may be realized by a CPU and a program that is analyzed and executed by the CPU, or may be realized as hardware by wired logic.
