Description

  The present invention relates to a farm work support apparatus, a farm work support method, and a farm work support program.

  In the cultivation of crops in agriculture, various operations occur during the period from harvesting of soil and sowing (seed sowing) through the growing stage to harvesting and shipping. The basic factor that determines the timing of various operations is the number of days the crop grows. Specifically, the work to be performed is roughly determined according to the number of days elapsed from the sowing date (seeding) or the day of planting or transplanting (planting seedlings in the field). For example, according to “Agricultural Technology System Cabbage Base 98”, it is recommended to perform additional fertilization (fertilizer sowing) 30 days and 80 days after seedling planting in cabbage.

  However, in reality, situations other than the number of growing days of crops need to be considered. For example, conditions that may vary from field to field, such as the occurrence of pests in the field (field), the state of the field (soil condition or the surrounding conditions of the field), or weather conditions, are important in determining the work to be performed. It becomes a factor.

  Specifically, as an operation according to the state of occurrence of pests, it is considered that pesticides are applied to the field when pests (such as larvae of white butterflies) are confirmed in cabbage after planting. . In addition, as work depending on the state of the field, it is conceivable to check around the ridges and check for water leaks when the water of the paddy rice after rice planting is drastically dried (decrease in water level). In addition, as work according to weather conditions or soil conditions, it is conceivable that, for example, three days after raining (one week in a field with poor drainage) are not performed in the preparation of soil before sowing.

  About what kind of work should be done depending on the number of growing days and the growing stage (growth stage), it is documented in the form of cultivation standard or guideline information for each crop like “Agricultural Technology System Cabbage Group 98”. Yes. In addition, a seedling manufacturer that sells seeds and seedlings describes information on an appropriate cultivation period for each crop or variety in a catalog or a seed container.

  In addition, it has been studied to use a computer system to determine work contents to be performed in consideration of not only the number of days of growth but also the growth state (for example, Patent Document 1).

JP 2007-310463 A

  However, the cultivation standard or guideline information is basic according to the number of growing days or the growing stage for each cropping type (spring-winter type, autumn-waki type) or rough climatic conditions (for example, cool land, intermediate land, warm land, etc.). To the extent that there is a description of the major operations (seeding, fertilization, harvesting).

  In the technique described in Patent Document 1, only a rough work type is presented.

  Therefore, it is difficult for an inexperienced worker to determine an appropriate work according to various situations using information that has been available in the past. In addition, when a plurality of work candidates are considered, it is difficult to determine which work is effective for crop growth within a limited time.

  This invention is made in view of said point, Comprising: It aims at provision of the farm work support apparatus, the farm work support method, and farm work support program which can support implementation of the suitable farm work according to the condition. .

  Therefore, in order to solve the above-described problem, the farm work support apparatus is executed when information indicating the state of the crop or information indicating the state of the environment, the condition regarding the state of the crop or the environment, and the condition are satisfied. A work rule information storage unit storing work rule information including work information indicating work to be performed and a degree of contribution of the work to the growth of the crop, and information indicating the state of the crop input or the state of the environment The work rule information extracting unit that extracts the work rule information including the condition that matches the information indicating the work rule information from the work rule information storage unit, and the work instruction unit that outputs the work information included in the extracted work rule information And when the plurality of work rule information is extracted, the work instruction unit outputs the work rule information to be output based on the contribution degree among the plurality of work rule information. To-option.

  It is possible to support the implementation of appropriate farm work according to the situation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a hardware configuration example of a farm work support apparatus according to an embodiment of the present invention. The farm work support apparatus 10 in FIG. 1 includes a drive device 100, an auxiliary storage device 102, a memory device 103, a CPU 104, an interface device 105, a display device 106, and an input device that are connected to each other via a bus B. 107.

  A program for realizing processing in the farm work support apparatus 10 is provided by a recording medium 101 such as a CD-ROM. When the recording medium 101 on which the program is recorded is set in the drive device 100, the program is installed from the recording medium 101 to the auxiliary storage device 102 via the drive device 100. However, the program need not be installed from the recording medium 101 and may be downloaded from another computer via a network. The auxiliary storage device 102 stores the installed program and also stores necessary files and data.

  The memory device 103 reads the program from the auxiliary storage device 102 and stores it when there is an instruction to start the program. The CPU 104 realizes functions related to the farm work support apparatus 10 according to a program stored in the memory device 103. The interface device 105 is used as an interface for connecting to a network. The display device 106 displays a GUI (Graphical User Interface) or the like by a program. The input device 107 is a keyboard, a mouse, or the like, and is used for inputting various operation instructions.

  FIG. 2 is a diagram illustrating a functional configuration example of the farm work support apparatus according to the embodiment of the present invention. In the figure, the farm work support apparatus 10 includes a growth state storage unit 111, a growth state update unit 112, a growth state update rule storage unit 113, a work rule storage unit 114, a work rule extraction unit 115, an extraction rule storage unit 116, a work instruction. Unit 117, work result input unit 118, work history storage unit 119, rule target achievement level input unit 120, observation result input unit 121, growth stage history storage unit 122, contribution level calculation unit 123, registration processing unit 124, and the like. . Each of these units is realized by processing executed by the CPU 104 by a program installed in the farm work support apparatus 10.

  The growth state storage unit 111 stores information (growth state information) indicating the growth state of each crop cultivated using the auxiliary storage device 102, for example. The growth state information is information indicating the growth state of the crop in units of time. For example, the growth state information includes a characteristic growth stage (growth stage) for each crop, the number of days elapsed from the start of cultivation, the number of days elapsed from the start of each growth stage, and the like. The growth stage refers to a period divided or classified with a predetermined time in the growing process of the crop as a break. For example, the approximate growth stages of crops are classified into “seeding period (seeding period)”, “nurturing period”, “growth period”, “harvest period”, and the like. However, depending on the crop, there is no “nursing season” or the “growing season” is finely classified. In addition, when the present embodiment is applied, an arbitrary growth stage may be defined.

  The growth state update unit 112 updates the growth state information stored in the growth state storage unit 111. The growing state update unit 112 autonomously updates the growing state of the crop for the predetermined period every predetermined period. For example, the growing state update unit 112 increases the number of elapsed days by one day every day. Moreover, the growth state update part 112 updates the growth stage of the said growth state, when a growth state corresponds to the conditions of one of the growth state update rules Ru.

  The growth state update rule Ru defines what is observed at a characteristic point in the growth process of the crop, how to update the growth state information as a result of the observation (update value of the growth state information), etc. It is data. That is, the growing state update rule Ru includes a characteristic time point of the growing process of the crop as a condition. The growth state update rule Ru includes contents to be observed when the condition is satisfied, an update value of the growth state information according to the observation result, and the like. The growth state update rule Ru is an example of state update rule information.

  The growth state update rule storage unit 113 stores, for example, one or more growth state update rules Ru using the auxiliary storage device 102. The growing state update rule storage unit 113 is an example of a state update rule information storage unit.

  The work rule storage unit 114 stores various work rules using, for example, the auxiliary storage device 102. The work rule is data defining what kind of work is to be performed on various states relating to the state of the crop, the field site and the surrounding state (the state of the crop environment). Specifically, the work rules include conditions relating to the crop growth state information or the state of the crop environment, work information indicating work to be performed when the conditions are satisfied, and the work rules for the growth of the crop (or the Work contribution). Details of the contribution will be described later.

  In the figure, as a work rule, a growth state rule Rs, an observation rule Ro, an environment rule Re, an alarm rule Rw, and the like are illustrated. Details of each work rule will be described later. In the present embodiment, the work rule is an example of work rule information. The work rule storage unit 114 is an example of a work rule information storage unit.

  The work rule extraction unit 115 is an example of a work rule information extraction unit. The work rule extraction unit 115 extracts (searches) from the work rule storage unit 114 a work rule including conditions that match input information such as information on the growth state of the crop, information on the field site and surrounding conditions, and the like. As an example of input information, the present embodiment relates to growth state information stored in the growth state storage unit 111, field observation result information by a person, and field environment (soil and weather) by various measuring instruments or sensors. Information, various types of warning information provided by weather information providers and agricultural organizations are used. Note that the types of work rules in the present embodiment correspond to the types of input information.

  The extraction rule storage unit 116 stores the work rules extracted by the work rule extraction unit 115 using, for example, the memory device 103.

  The work instruction unit 117 causes the display device 106 to output work information and the like included in the work rules stored in the extraction rule storage unit 116, for example. When a plurality of work rules are stored in the extraction rule storage unit 116 (that is, when a plurality of work rules are extracted), the work instruction unit 117 is based on the degree of contribution included in each work rule. Then, select (limit) a work rule to be output as work information. That is, priority is given to a work rule having a relatively high contribution. That is, the contribution is used as a priority (priority order) when a plurality of work rules compete.

  Note that the execution timing of the processing by the work rule extraction unit 115 and the work instruction unit 117 may be performed each time input information is input. Alternatively, it may be a preset timing or a regular time (a predetermined time every day).

  The work result input unit 118 accepts input of information (work result information) indicating the work result instructed by the work instruction unit 117 and records it in the work history storage unit 119. The work history storage unit 119 stores the history of work performance information using, for example, the auxiliary storage device 102. The work history storage unit 119 is an example of a first evaluation value storage unit.

  The rule target achievement level input unit 120 receives an input of an evaluation value (rule target achievement evaluation value) indicating an achievement level (achievement status) for a target (rule target) included in each work rule, and a work history storage unit 119. To record. Therefore, the rule target achievement evaluation value is recorded for each work rule related to the work instructed by the work instruction unit 117. The rule target achievement evaluation value is an example of a first evaluation value. The rule target achievement level input unit 120 is an example of a first evaluation value input unit.

  The observation result input unit 121 receives an input of a result of observation of a crop or the like performed according to an observation instruction of the crop or the like output by the growth state update unit 112. The observation result input unit 121 calculates an evaluation value (stage target achievement evaluation value) indicating an achievement level (achievement status) with respect to a target (stage target) provided for each growth stage of the crop based on the input observation result. Record in the growth stage history storage unit 122. Therefore, the stage target achievement evaluation value for a certain crop is recorded for each growth stage of the crop. The stage target achievement evaluation value is an example of a second evaluation value. The observation result input unit 121 is an example of a second evaluation value input unit.

  The growth stage history storage unit 122 records information about each growth stage in accordance with the progress of the crop growth stage. The information regarding each stage includes a stage goal achievement evaluation value. The growth stage history storage unit 122 is an example of a second evaluation value storage unit.

  The contribution calculation unit 123 obtains an index value indicating a correlation between the stage target achievement evaluation value of the growth stage and the rule target achievement evaluation value of each work rule applied in the growth stage, for each growth stage, Record the index value as a contribution in each work rule. That is, the contribution degree of each work rule is determined based on the correlation between the achievement level of each work rule and the achievement level of the stage goal.

  The registration processing unit 124 receives an input of the growth state update rule Ru or various work rules, and records the input growth state update rule Ru or the work rule in the growth state update rule storage unit 113 or the work rule storage unit 114. For example, the registration processing unit 124 causes the display device 106 to display an input screen corresponding to each type of growth state update rule Ru or work rule. The registration processing unit 124 generates a growth state update rule Ru or a work rule based on the input content on the input screen, and records it in the growth state update rule storage unit 113 or the work rule storage unit 114.

  Hereinafter, the processing procedure of the farm work support apparatus 10 will be described. FIG. 3 is a flowchart for explaining an example of the processing procedure of the growth state update processing. The process shown in FIG. Here, it will be executed once a day at a predetermined time.

  In step S <b> 101, the growth state update unit 112 periodically updates the growth state information stored in the growth state storage unit 111.

  FIG. 4 is a diagram illustrating a configuration example of the growth state information. In this figure, the growth state information includes cultivation ID, crop name, variety, crop type, cultivation method, cultivation start date, elapsed days, current growth stage, current growth stage start date, current growth stage elapsed days, and growth stage start date. And the growth stage end date.

  The cultivation ID is a unique identifier for each cultivation of the crop. “Cultivation” refers to the period from the start of crop cultivation or preparation for cultivation until the crop is harvested and various operations during that period. The field ID is an identifier for the field. The unit of the farm field may be determined as appropriate according to the farm to which this embodiment is applied.

  The crop name is the name of the crop. For example, “rice”, “wheat”, and the like correspond to crop names. A variety is a variety of crops. For example, in the case of rice, Koshihikari, Sasanishiki and the like correspond to varieties. The cropping type is a crop cultivation system such as a spring and autumn type. The cultivation method is a crop cultivation method. The cultivation start date is a date when cultivation is started. The elapsed days are the elapsed days from the cultivation start date. The current growth stage is the current growth stage of the crop. The current growth stage start date is the date when the current growth stage is entered. The elapsed days in the current growth is the elapsed days after shifting to the current growth stage. The growth stage start date and the growth stage end date are the start date or the end date of the growth stage that has passed so far. In the case of passing through a plurality of growth stages, the growth stage start date and the growth stage end date are included for each growth stage.

  In the growth state information, the field ID, the crop name, the collection, the cropping type, the cultivation method, and the like correspond to information on the cultivation conditions of the crop. After the cultivation start date, it corresponds to information indicating the growth state of the crop. That is, in the present embodiment, the state of crop growth is managed in units of time or by the elapsed time from a predetermined time. Regarding the cultivation start date, for example, not the actual cultivation start date but the day after the harvest of the previous crop (for example, the day after the harvest date of the previous crop) may be used as the cultivation start date of the crop. This is because there are cases where it is necessary to work on the field for cultivation of crops (cultivation, leveling, fertilization, paddy, shaving) before cultivation (for example, sowing) of the crop actually begins.

  The growth state information shown in FIG. 4 is stored in the growth state storage unit 111 for each cultivation. The processing procedure of FIG. 3 is executed for each growth state information stored in the growth state storage unit 111. However, here, for the sake of convenience, description will be given focusing on one piece of growth state information.

  The periodic automatic update in step S101 means that 1 is added to each of the elapsed days and the current growing elapsed days in the growth state information. For example, if the period in which FIG. 3 is executed is 2 days, 2 may be added.

  Subsequently, the growing state update unit 112 searches the growing state update rule Ru stored in the growing state update rule storage unit 113 for a growing state update rule Ru that includes a condition that matches the growing state information (S102). ).

  FIG. 5 is a diagram illustrating a configuration example of the growth state update rule. In the figure, the growth state update rule Ru includes a rule ID, registration source, registration date, crop name, variety, cropping type, cultivation method, growth stage, elapsed days, redundant days, redundant classification, work necessity / pre-observation rules ID, advance required work, destination growth stage, number of days in destination growth, stage target achievement evaluation value, etc. are included.

  The rule ID is a unique identifier for each growth state update rule Ru. The registration source is information indicating an information source or a registrant of the growing state update rule Ru. That is, in the present embodiment, it is assumed that each worker registers the growth state update rule Ru and the work rule with reference to various types of information. Therefore, for example, by evaluating the reliability of the growth state update rule Ru, by clearly storing who or what information source or the like has been used to register the growth state update rule Ru or the work rule. can do. The registration date is the date when the growing state update rule Ru is registered.

  From the crop name to the redundant classification are parameters that constitute conditions (hereinafter referred to as “growth state conditions”) for the growth state information in the growth state update rule Ru. Among the parameters, the crop name, cultivar, cropping type, cultivation method, growth stage, and elapsed days are as described for the growth state information (FIG. 4). However, the elapsed days are the elapsed days in the growth stage.

  The redundant days is a parameter for providing redundancy to the condition of elapsed days. That is, redundancy is added to the condition of the elapsed days by the number of days specified as the number of redundant days.

  The redundancy classification is a parameter indicating in which direction of the elapsed days the redundancy days are given. The redundancy classification takes values of “front and rear”, “front”, and “rear”. “Before and after” indicates that redundant days are given before and after the elapsed days. Therefore, in the case of the example of the figure with the elapsed days and the redundant days, when the redundant division is “before and after”, the condition of the elapsed days is “35 to 45”. “Previous” indicates that redundant days are given before the elapsed days. Therefore, in this case, the condition of the elapsed days is “35-40”. “After” indicates that redundant days are given after the elapsed days. Therefore, in this case, the condition of the elapsed days is “40 to 45”.

  The transfer destination growth stage and the number of days elapsed in the transfer destination growth are parameters that constitute the content of the update process for the growth state information that matches the growth state condition of the growth state update rule Ru. That is, the transfer destination growth stage indicates an updated value (updated value) of the current growth stage of the growth state information. Elapsed days in the transfer destination growth indicates an updated value of the elapsed days in the current growth of the growth state information.

  The necessity of work, pre-observation rule ID, and pre-necessary work are additional conditions for the growth state condition. That is, the prior observation rule ID is a condition relating to the actual crop observation state. Specifically, the prior observation rule ID is the rule ID of the observation rule Ro that is referred to (included) by the growth state update rule Ru. The observation rule Ro is a rule that defines the observation contents regarding crops, soil, and the like. When the growth state information satisfies the growth state condition of the growth state update rule Ru, the operator is required to observe the crops and the like according to the observation rule Ro related to the prior observation rule ID and input the observation result. The When the observation result does not satisfy the conditions defined in the observation rule Ro, the growth state information is not updated.

  The necessity / unnecessity of work indicates the necessity / unnecessity of work indicated in the prenecessary work. In other words, if the value of work necessity is “necessary”, the pre-necessary work is required. When the work necessity value is “unnecessary”, the pre-necessary work is not required. The pre-necessary work is a work that is a premise of the update process of the growth state information. That is, when the work designated as the pre-necessary work is not performed, the growth state information is not updated. The pre-necessary work is a parameter that is effective when the work necessity value is “necessary”.

  When the growth stage is updated by applying the growth state update rule Ru, the stage target achievement evaluation value is relative to the growth stage before the update (that is, the growth stage according to the growth state update rule Ru). It is the stage goal achievement evaluation value given.

  In step S102, the growth state conditions defined by the parameters from the crop name to the redundant classification match the crop name, cultivar, cropping type, cultivation method, current growth stage, and elapsed days in the current growth state in the growth state information. The growing state update rule Ru to be searched is searched. Usually, a plurality of growth state update rules Ru having different stage goal achievement evaluation values are searched. In other words, a growth state update rule Ru having a common growth state condition and an additional condition and different in advance observation rule ID and stage target achievement evaluation value is registered in the growth state update rule storage unit 113 in advance.

  When no corresponding growth state update rule Ru is searched (NO in S103), the process in FIG. 3 ends. When a corresponding growth state update rule Ru (hereinafter referred to as “current growth state update rule Ru”) is searched (YES in S103), the growth state update unit 112 determines whether the current growth state update rule Ru is necessary. It is determined whether or not the value is “necessary” (S104). Here, there are usually a plurality of current growth state update rules Ru. However, the value of work necessity / preliminary work value of each current growth state update rule Ru is registered in common. Therefore, the determination in step S104 may be performed based on any one of the plurality of current growth state update rules Ru.

  If the work necessity value is “unnecessary” (NO in S104), the process proceeds to step S107. When the value of the necessity of work is “necessary” (YES in S104), the growth state update unit 112 determines whether or not the work designated as the pre-required work is performed for the crop related to the growth state information. Confirmation is made with reference to the history storage unit 119 (S105).

  FIG. 6 is a diagram illustrating a configuration example of the work history storage unit. In the figure, the work history storage unit 119 has a cultivation ID, a field ID, a crop name, a cropping type, a cultivation method, a growth stage, a work name, a rule ID, a work date, and a rule for each work executed according to the work rules. The target achievement evaluation value and the like are stored.

  The cultivation ID, the field ID, the crop name, the cropping type, the cultivation method, and the growth stage are the cultivation ID, the field ID, the crop name, and the cropping type that are stored in the growth state storage unit 111 at the time of work for the crop that is the target of the work. , Cultivation method, current growth stage.

  The work name is the name of the work performed according to the work rule. The rule ID is the rule ID of the work rule that caused the work. The work date is the date when the work was performed. The rule target achievement evaluation value is a target achievement evaluation value for a target included in the work rule.

  Thus, the work history storage unit 119 stores information related to work performed in the past. In step S105, among the records recorded in the work history storage unit 119, the cultivation ID, the field ID, the crop name, the cropping type, the cultivation method, and the growth stage are the cultivation ID, the field ID, and the crop name of the growth state information. Whether or not there is a record that matches the cropping type and the growth stage and whose work name matches the work name specified in the pre-required work of the current growth state update rule Ru is confirmed.

  When there is no corresponding record (when the pre-necessary work is not performed) (NO in S106), the process of FIG. 3 ends. When there is a corresponding record (when pre-necessary work is performed) (YES in S106), the growth state update unit 112 has an observation rule having a pre-observation rule ID as a rule ID for each current growth state update rule Ru. Ro is searched from the work rule storage unit 114 (S107).

  FIG. 7 is a diagram illustrating a configuration example of an observation rule referred to by the growth state update rule. In the figure, the observation rule Ro includes a rule ID, a registration source, a crop name, a variety, a cropping type, a cultivation method, a growth stage, a rule linkage, an observation target, an observation state, a candidate work, a rule target, a target achievement confirmation method, And contributions. The rule ID, registration source, registration date, and the like are as described for the growth state update rule Ru (FIG. 5).

  The rule linkage indicates the presence or absence of linkage with the growth state update rule Ru or the growth state rule Rs. For the observation rule Ro, cooperation refers to reference from other rules. The observation rule Ro independently constitutes one work rule, but is sometimes referred to from the growth state update rule Ru and the growth state rule Rs and may constitute a part of the reference source rule.

  The observation target and the observation state are parameters that constitute the conditions of the observation rule Ro. The observation object and the observation object are shown. The observation state indicates a comparison value to be compared with the observation result for the observation target for applying the observation rule Ro. That is, when the state of the observation target matches the state shown in the observation state, the observation rule Ro is applied.

  The candidate work and subsequent parameters are effective when there is no rule linkage. Therefore, these parameters are invalid for the observation rule Ro referred to by the growth state update rule Ru. Therefore, the description regarding these parameters is omitted here.

  Note that the observation rule Ro without rule cooperation defines an operation to be performed when the observation target is in a state indicated by the observation state. On the other hand, the observation rule Ro (observation rule Ro having rule cooperation) referred to by other rules is used to determine whether or not the observation target is in a state indicated by the observation state. For example, the observation rule Ro shown in FIG. 7 is used to determine whether or not the ratio of the area of the field where the number of true leaves reaches four is 20% to 49%.

  In step S107, the observation rule Ro is searched for each of the plurality of current growth state update rules Ru. Therefore, at the time of step S107, the growth state update unit 112 has, for example, a growth state update rule Ru and an observation rule Ro as shown in FIG.

  FIG. 8 is a diagram illustrating an example of a growth state update rule and an observation rule that are processing targets in the growth state update process.

  In the figure, three growth state update rules Ru101 to 103 and observation rules Ro101 to 103 referred to by the respective growth state update rules Ru are shown. In addition, each growth state update rule Ru and each observation rule Ro of the same figure show only items necessary for explanation.

  The following three points should be noted here. First, the stage goal achievement evaluation values of the respective growth state update rules Ru are different. Second, the observation target of each observation rule Ro is common. Third, the observation state of each observation rule Ro is different.

  For example, regarding the first point, the stage goal achievement table or value of each growth state update rule Ru is “50”, “70”, “100”. Regarding the second point, the observation target of each observation rule Ro is “ratio (%) of the area of the field where four true leaves have reached”. Regarding the third point, the observation state of each observation rule Ro is “20 to 49”, “50 to 99”, and “100”.

  Subsequently, the growth state update unit 112 causes the operator to observe whether or not the observation target is in the observation state based on the observation target and the observation state included in the searched observation rule Ro. The instruction is displayed on the display device 106 (S108). For example, a screen including a message indicating the instruction (hereinafter referred to as “observation instruction screen”) is displayed. In the case of the observation rule Ro shown in FIG. 8, a message for instructing observation of “the ratio (%) of the area of the field where four true leaves have reached” is displayed on the observation instruction screen.

  Subsequently, the observation result input unit 121 receives an input of the observation result by an operator who has observed the observation target (S109). The observation result is input via an observation result input screen that the observation result input unit 121 displays on the display device 106.

  In the case of the observation rule Ro as shown in FIG. 8, the observation result input screen only needs to have a character string input component for input indicating the percentage (%) of the area of the field where the main leaf has reached four pieces. . Alternatively, the observation result input screen has check boxes including four options corresponding to the values of the respective observation states of the three observation rules Ro and the fact that none of the observation states of the three observation rules Ro is applicable. It may be. Furthermore, a screen for selecting whether the observation result corresponds to the observation state (“YES”) or not (“NO”) may be displayed for each observation rule Ro.

  In any form, a value comparable to the observation state of the observation rule Ro is input as the observation result.

  Subsequently, the observation result input unit 121 determines whether or not there is an observation rule Ro that matches the observation state with the input observation result (S110). For example, it is determined whether or not the input observation result matches the observation state of any of the three observation rules Ro in FIG. When there is no observation rule Ro that matches the observation result (NO in S110), the observation result input unit 121 ends the process of FIG. Therefore, in this case, the growth state information is not updated based on the growth state update rule Ru. For example, in the case of FIG. 8, the growth state information is not updated if the observation result of the ratio of the area of the field where the number of true leaves reaches four is less than 20%.

  On the other hand, when there is an observation rule Ro that matches the observation result (YES in S110), the growth state update unit 112 refers to the observation rule Ro that matches the observation result in response to a request from the observation result input unit 121. The growth state information is updated according to the current growth state update rule Ru (S111). For example, in the case of FIG. 8, even if the observation result matches any observation rule Ro, the current growth stage of the growth state information (FIG. 4) is updated to “initial heading”, and the number of days elapsed in the current growth is , “1”.

  In addition, the current growth stage start date is updated to the date of the current day. Further, when the current growth stage of the growth state information is different before and after the update, the growth stage start date and the growth stage end date related to the current growth stage before the update are added to the growth state information. The current growth stage start date before update is posted on the growth stage start date. The date of the day is recorded as the growth stage end date.

  Depending on the observation result, the elapsed days of the new growth stage (the elapsed days in the current growth) may be different. For example, when the ratio of the area of the field where the number of true leaves reaches 4 is 50% to 99%, the elapsed days may be “2”, and when 100%, the elapsed days may be “5”. . In that case, the values of the elapsed days in the transfer destination growth of the growth state update rules Ru102 and 103 in FIG. 8 may be “2” and “5”, respectively.

  Thus, by changing the elapsed days in the new growth stage according to the observation result, the contents of the growth state information can be approximated to the actual growth state of the crop.

  Subsequently, the observation result input unit 121 determines whether or not the value of the current growth stage of the growth state information has changed (has progressed) by the processing in step S111 (S112). When the value of the current growth stage of the growth state information has not changed (NO in S112), the observation result input unit 121 ends the process of FIG. Usually, the growth state update rule Ru is applied to update the growth stage. Further, at the time of step S112, the growing state update rule Ru has already been applied. Nevertheless, the determination in step S112 is required because the growth state update rule Ru can be used for purposes other than the update of the growth stage. This point will be described later.

  On the other hand, when the value of the current growth stage of the growth state information has changed (YES in S112), the observation result input unit 121 records one record (growth stage information) regarding the completed growth stage (the growth stage before the update), It records in the growth stage history memory | storage part 122 (S113).

  FIG. 9 is a diagram illustrating a configuration example of the growth stage history storage unit. In the figure, the growth stage history storage unit 122 has a cultivation ID, a field ID, a crop name, a cropping type, a cultivation method, a growth stage, a stage start date, a stage end date, and a stage target achievement evaluation for each past growth stage. Stores the value etc.

  The cultivation ID, field ID, crop name, cropping type, and cultivation method of the growth state information are recorded in the cultivation ID, field ID, crop name, cropping type, and cultivation method of the newly added record. In the growth stage, the value of the current growth stage before update is recorded. As the growth stage start date and the growth stage end date, the “growth stage start date” and “growth stage end date” added last (that is, the newest) to the growth state information are recorded. As the stage target achievement evaluation value, the stage target achievement evaluation value included in the growth state update rule Ru applied in step S111 is recorded. Therefore, for example, when the growth state update rule Ru101 shown in FIG. 8 is applied, “50” is recorded in the stage target achievement evaluation value of the growth stage history storage unit 122. When the growth state update rule Ru102 is applied, “70” is recorded in the stage target achievement evaluation value of the growth stage history storage unit 122. When the growth state update rule Ru103 is applied, “100” is recorded in the stage target achievement evaluation value of the growth stage history storage unit 122.

  Here, the growing state update rule Ru to be applied is selected based on the actual observation result. Therefore, the growth stage target achievement evaluation value is recorded based on the actual observation result (that is, the growth state). It can be said that the input of the observation result substantially corresponds to the input of the stage target achievement evaluation value.

  In the above description, the example in which the growth stage is updated according to the growth state of the crop (growth progress) has been described. However, a growth stage that ends by performing a predetermined operation can also be defined. That is, the term “growth stage” may include the meaning of “working stage”. This is because what kind of growth stage is defined is arbitrary according to the operation.

  For example, suppose that the “cabbage preparation period” is defined as a growth stage for the soil making stage before sowing. In this case, the “cabbage preparation period” ends with the completion of soil preparation.

  The growth stage that ends by performing a predetermined operation is also effective for the processing procedure described in FIG. In this case, for example, a growth state update rule Ru and an observation rule Ro as shown in FIG. 10 may be defined.

  FIG. 10 is a diagram illustrating an example of a growth state update rule and an observation rule related to a growth stage that ends upon completion of work. FIG. 10 shows the growth state update rule Ru and the observation rule Ro in the same format as in FIG. Each growth state update rule Ru in FIG. 10 is applied to the “cabbage preparation period” (that is, the value of the growth stage is set to “cabbage preparation period”), and the growth state is updated to update the growth stage to “seeding period”. Rule Ru.

  Further, the observation target of each observation rule Ro referred to by each growth state update rule Ru is common as “the number of days from the completion of the work to the scheduled sowing date”. In the present embodiment, with respect to the “cabbage preparation period”, “the number of days from the completion of the work to the scheduled sowing date” is set as the observation target. This is because it is desirable. Although omitted in the figure, for example, “soil making” is set in the work necessary in advance for each growth state update rule Ru in the figure. That is, the name of the work whose completion of the work is the end of the growth stage is set as the pre-necessary work.

  The observation state of the observation rule Ro204 is “3 days to less than one week”. The observation state of the observation rule Ro205 is “less than 1 to 1 week”. The observation state of the observation rule Ro206 is “two weeks or more”.

  Therefore, by setting the growth state update rule Ru and the observation rule Ro as shown in FIG. 10 as processing targets, the stage target achievement evaluation value can be changed according to the time when the soil formation is completed. If generalized, the stage target achievement evaluation value can be changed in accordance with the result of the work regarding the growth stage that ends upon completion of the work.

  In the case of FIG. 10, the growth stage is not updated when the number of days from completion of soil preparation to the scheduled sowing date is less than 3 days.

  By the way, in the above, it was described that the growth state update rule Ru can be used for purposes other than the update of the growth stage. This will be described.

  The growth state update unit 112 of the present embodiment periodically adds 1 to the elapsed days (step S101 in FIG. 12). However, the actual growth state of the crop does not necessarily correspond to the elapsed days. Specifically, the growth may be delayed compared to the actual number of days elapsed. Therefore, the growing state update rule Ru can also be used as a means for correcting the growth delay. In this case, for example, the growth state update rule Ru shown in FIG. 11 may be added to the growth state update rule Ru shown in FIG.

  FIG. 11 is a diagram illustrating an example of a growth state update rule and an observation rule for correcting growth state information according to an actual growth state.

  The growth state update rule Ru shown in the figure is the same as the growth state update rule Ru shown in FIG. 5, and the growth state update rule Ru to be processed during the period of 35 to 45 days in the planting period. It is. However, the transfer destination growth stage of the two growth state update rules Ru in FIG. 11 is set to the same “fixed planting period” as the current growth stage. Further, the elapsed daily income within the transfer destination growth is “20” or “30”, which is a value smaller than 35 to 45 days (that is, the growth state (elapsed days before the growth state matching the growth state condition). )). Since these growth state update rules Ru are not for generating an update of the growth stage, the stage target achievement evaluation value is empty or invalid.

  The observation target of the observation rule Ro referred to by each of the two growth state update rules Ru is “the ratio (%) of the area of the field where four true leaves have reached”, as in FIG. 5 or FIG. The observation state of the observation rule Ro211 is “0-9”. The observation state of the observation rule Ro212 is “10 to 19”.

  Consider a case where, at the time of step S108 in FIG. 3, the growth state update rule Ru shown in FIG. 11 is the processing target in addition to the growth state update rule Ru shown in FIG. In this case, when a value indicating 0% to 9% is input as an observation result in step S108, the growth state update rule Ru having the rule ID “111” in FIG. 11 is applied. As a result, in step S111, the current growth stage of the growth state information is not updated, and the elapsed days in the current growth is returned to “20”.

  Thus, based on the observation result, the growth state information can be updated in the reverse direction to the growth direction based on the growth state update rule Ru. Therefore, the value of the elapsed days in the current growth in the growth state information that is periodically updated can be corrected to a value that approximates the actual growth state.

  Subsequently, a process of extracting work rules that are candidates for application according to the growth state indicated by the growth state information managed as described above or other factors will be described.

  First, work rule extraction processing according to the growth state will be described. FIG. 12 is a flowchart for explaining an example of a processing procedure of work rule extraction processing according to a growing state. The process shown in FIG. For example, it may be performed after the growth state information is updated by the growth state update unit 112.

  In step S <b> 201, the work rule extraction unit 115 acquires growth state information (FIG. 4) from the growth state storage unit 111. Note that the processing procedure of FIG. 12 is executed for each growth state information stored in the growth state storage unit 111. However, here, for the sake of convenience, description will be given focusing on one piece of growth state information.

  Subsequently, the work rule extraction unit 115 searches the growth state rule Rs stored in the work rule storage unit 114 for a growth state rule Rs including a growth state condition that matches the growth state information (S202).

  FIG. 13 is a diagram illustrating a configuration example of a growth state rule. The growth state rule Rs is a work rule that defines conditions for the growth state of crops and work to be performed when the conditions are satisfied. In the figure, the growth state rule Rs is a rule ID, registration source, registration date, crop name, variety, cropping type, cultivation method, growth stage, elapsed days, redundant days, redundant classification, prior observation / work necessity, prior It includes observation rule ID, pre-necessary work, candidate work, work cycle days, maximum number of work repetitions, rule target, target achievement confirmation method, contribution degree, and the like.

  The rule ID, the registration source, and the registration date are as described for the growth state update rule Ru (FIG. 5) and the like.

  From the crop name to the redundant classification are parameters constituting conditions (growth state conditions) for the growth state information in the growth state rule Rs. The meaning of each parameter is as described for the growth state update rule Ru.

  The prior observation / work necessity, the prior observation rule ID, and the prior necessary work are additional conditions for the growth state condition. That is, the necessity for prior observation / work is a parameter indicating whether observation or a predetermined work needs to be performed in advance in order to apply the growth state rule Rs. The value of necessity of prior observation / work is one of “none”, “observation”, “work”, or “observation / work”. “None” indicates that there is no need for both observation and work. “Observation” indicates that only observation is necessary. “Work” indicates that only work is necessary. “Observation / work” indicates that it is necessary for both observation and work.

  The prior observation rule ID and the meaning of the pre-required work are as described for the growth state update rule Ru. That is, the observation state rule can also refer to the observation rule Ro. However, the pre-observation rule ID is effective when the value of the pre-observation / work necessity is “observation” or “observation / work”. The pre-necessary work is effective when the value of the pre-observation / work necessity is “work” or “observation / work”.

  The candidate work, the work cycle days, and the maximum work repetition number are parameters relating to work to be performed when the growth state condition and additional conditions of the growth state rule Rs are satisfied.

  The candidate work is the name of the work to be performed. Here, the term “candidate” is given because, when there is a conflict with another work rule, the candidate work is not necessarily a work to be executed. The work cycle days indicate a cycle when the candidate work needs to be performed periodically. The maximum number of work repetitions is an upper limit value of the number of repetitions when the candidate work needs to be periodically performed.

  The rule target is a target of the work performed based on the target of the growing state rule Rs or the growing state rule Rs. The target achievement confirmation method is a confirmation method (evaluation method) of a rule goal achievement (rule target achievement evaluation value). The degree of contribution is the degree or degree to which the growth state rule Rs contributes to the stage target of the growth stage to which the work rule (here, the growth state rule Rs) is applied. That is, the contribution degree can be said to be a degree or a degree that the work rule contributes to the crop growth.

  In step S202, the growth state condition defined by the parameters from the crop name to the redundant classification matches the crop name, variety, cropping type, cultivation method, current growth stage, and elapsed days in the current growth state. The growing state rule Rs to be searched is searched.

  If the corresponding growth state rule Rs is not searched (NO in S203), the process in FIG. 12 ends. When the corresponding growth state rule Rs (hereinafter referred to as “current growth state rule Rs”) is searched (YES in S203), the work rule extraction unit 115 determines whether the current growth state rule Rs is to be observed in advance / work is necessary or not. It is determined whether the value is “work” or “observation / work” (S204). That is, it is determined whether or not the pre-necessary work is designated.

  If the pre-observation / work necessity value is not “work” or “observation / work” (NO in S204), the process proceeds to step S207. When the value of the pre-observation / work necessity is “work” or “observation / work” (YES in S204), the work rule extraction unit 115 determines whether the work designated as the pre-necessary work is being performed. Is confirmed with reference to the work history storage unit 119 (FIG. 6) (S205). The content of step S205 is the same as the content of step S105 in FIG. That is, among the records recorded in the work history storage unit 119, the cultivation ID, the field ID, the crop name, the cropping type, the cultivation method, and the growth stage are the cultivation ID, the field ID, the crop name, and the production stage of the growth state information. It is confirmed whether there is a record that matches the type, cultivation method, and growth stage, and the work name matches the work name specified in the pre-necessary work.

  When there is no corresponding record (when a pre-necessary work is not performed) (NO in S206), the process in FIG. 12 ends. If there is a corresponding record (when pre-necessary work is performed) (YES in S206), the work rule extraction unit 115 refers to the work history storage unit 119 and designates it as a candidate work for the current growth state rule Rs. It is determined whether or not the work being performed has been completed (S207). That is, the rule ID, cultivation ID, field ID, crop name, cropping type, which matches the rule ID, cultivation ID, field ID, crop name, cropping type, cultivation method, growth stage, and candidate work of the current growth state rule Rs, The presence / absence of a record including a cultivation method, a growth stage, and a work name is determined. When the work cycle and the maximum number of work repetitions are specified in the current growth state rule Rs, the work day interval of the corresponding record is the work period, and whether the number of the corresponding records has reached the maximum number of work repetitions. Is also determined. That is, in step S207, when the work designated as the candidate work is performed for the maximum number of work repetitions in the current growth stage in the cycle designated as the work cycle based on the current growth state rule Rs, It is determined that the candidate work has been completed.

  If the candidate work has been completed (YES in S207), the process in FIG. 12 ends. This is to avoid the same growth state rule Rs being applied to one crop.

  If execution of the candidate work is not completed (NO in S207), the work rule extraction unit 115 determines whether the value of prior observation / work necessity in the current growth state rule Rs is “observation” or “observation / work”. It is determined whether or not (S208). That is, it is determined whether or not the observation is required.

  If the value of the pre-observation / work necessity necessity of the current growth state rule Rs is not “observation” or “observation / work” (NO in S208), the process proceeds to step S213. When the value of the pre-observation / work necessity necessity of the current growth state rule Rs is “observation” or “observation / work” (YES in S208), the work rule extraction unit 115 determines the pre-observation rule ID of the current growth state rule Rs. Is searched for from the work rule storage unit 114 (S209).

  Subsequently, the work rule extraction unit 115 causes the worker to observe whether the observation target is in the observation state based on the observation target and the observation state included in the searched observation rule Ro. The instruction is displayed on the display device 106 (S210). Subsequently, the work rule extraction unit 115 receives an input of an observation result by an operator who has observed the observation target (S211).

  Subsequently, the work rule extraction unit 115 determines whether or not the input observation result matches the observation state of the observation rule Ro (S212). If the observation result matches the observation rule Ro (YES in S212), the work rule extraction unit 115 records the current growth state rule Rs in the extraction rule storage unit 116 (S213). That is, the current growth state rule Rs is extracted as an application candidate.

  When the observation result does not match the observation rule Ro (NO in S212), the current growth state rule Rs is not recorded in the extraction rule storage unit 116.

  Next, a process for extracting work rules according to observation information will be described. FIG. 14 is a flowchart for explaining an example of a processing procedure of work rule extraction processing according to observation information.

  In step S301, the work rule extraction unit 115 acquires observation information (observation target and observation state). The observation information here is not limited to the observation information obtained by the observation performed in response to the instruction output by the execution of FIG. 3 or FIG. That is, the observation information here is based on observations made by the worker during farming work, apart from the instruction based on the observation rule Ro referred to from the growth state update rule Ru or the observation rule Ro referred to from the growth state rule Rs. The observation information obtained is also included. Note that the observation information in step S301 may be acquired by causing the operator to input an observation target and an observation state via an observation result input screen displayed by the work rule extraction unit 115. Alternatively, the observation target and the observation state that are input asynchronously with the processing of FIG. 14 and are stored in the auxiliary storage device 102 may be acquired. The former form is suitable when the process of FIG. 14 is executed in response to input of observation information. The latter form is suitable when the process of FIG. 14 is performed periodically.

  Subsequently, the work rule extraction unit 115 acquires the growth state information from the growth state storage unit 111 (S302). In addition, the process procedure after step S302 is performed about each growth state information memorize | stored in the growth state memory | storage part 111. FIG. However, here, for the sake of convenience, description will be given focusing on one piece of growth state information.

  Subsequently, the work rule extraction unit 115 searches the work rule storage unit 114 for an observation rule Ro that includes a condition that matches the growth state information and the observation information (S303).

  FIG. 15 is a diagram illustrating a configuration example of an observation rule as a work rule. The observation rule Ro as a work rule means an observation rule Ro that independently constitutes one work rule, not an observation rule Ro (for example, FIG. 7) that is referred to by other rules. Hereinafter, when referring to the explanation of FIG. 14, the observation rule Ro refers to the observation rule Ro as a work rule.

  The observation rule Ro is a work rule that defines a condition for observation information regarding the growth state of a crop and a crop or a field (soil, etc.) and a work to be executed when the condition is satisfied. The meaning of each parameter shown in the figure is as described in FIG. That is, in this embodiment, there is no structural difference between the observation rule Ro as the work rule and the observation rule Ro that is referred to by other rules. However, the value of the rule linkage of the observation rule Ro as the work rule is “None”. In the observation rule Ro as the work rule, the candidate work, the rule target, the target achievement confirmation method, and the contribution are effective parameters. The meaning of these parameters is as described for the growth state rule Rs in FIG.

  Note that the observation rule Ro in FIG. 15 includes two sets of observation objects and observation states. Thus, the observation rule Ro can also include two or more sets of observation objects and observation states. When a plurality of sets of observation targets and observation states are included, whether or not a condition is satisfied for the observation information is evaluated by a logical product (AND) of each set. Note that a plurality of sets of observation targets and observation states can be included in the same manner for the observation rule Ro referred to by other rules.

  In step S303, an observation rule Ro that matches the crop name to the growth stage with respect to the growth state information and matches the observation target and the observation state with respect to the observation information is searched.

  If the corresponding observation rule Ro is not searched (NO in S304), the process in FIG. 14 ends. When the corresponding observation rule Ro is searched (YES in S304), the work rule extraction unit 115 records the searched observation rule Ro in the extraction rule storage unit 116 (S305). That is, the observation rule Ro is extracted as an application candidate.

  Next, the work rule extraction process according to the environment information will be described. FIG. 16 is a flowchart for explaining an example of a processing procedure of work rule extraction processing according to environment information. The process of FIG. 16 is executed periodically, for example.

  In step S <b> 401, the work rule extraction unit 115 acquires environment information from the auxiliary storage device 102. The environmental information refers to information (particularly weather information) regarding the field environment such as temperature, solar radiation, humidity, and precipitation. The environmental information is measured by, for example, various measuring instruments or sensors (thermometers, hygrometers, etc.) installed in the farm field and recorded in the auxiliary storage device 102. However, the processing result of the measured value by various measuring instruments etc. may be used as environment information. The processing results include, for example, average temperature, maximum temperature, minimum temperature, accumulated temperature, accumulated precipitation amount, and the like. That is, the processing result is not a value obtained instantaneously but a value obtained based on a measured value for a certain period. Recording in the auxiliary storage device 102 may be performed automatically by connecting a measuring instrument or the like and the farm work support apparatus 10 via a network, or may be performed by manual input.

  Subsequently, the work rule extraction unit 115 acquires the growth state information from the growth state storage unit 111 (S402). In addition, the process procedure after step S402 is performed about each growth state information memorize | stored in the growth state memory | storage part 111. FIG. However, here, for the sake of convenience, description will be given focusing on one piece of growth state information.

  Subsequently, the work rule extraction unit 115 searches the work rule storage unit 114 for an environment rule Re that includes conditions that match the growth state information and the environment information (S403).

  FIG. 17 is a diagram illustrating a configuration example of an environment rule. The environment rule Re is a work rule that defines conditions for the growth state of the crop and the environment of the field and work to be performed when the conditions are satisfied. In the figure, the environment rule Re includes a rule ID, a registration source, a crop name, a variety, a cropping type, a cultivation method, a growth stage, a measurement target, a measurement state, a candidate operation, a rule target, a target achievement confirmation method, and a contribution degree. Etc. The rule ID, registration source, registration date, and the like are as described for the growth state update rule Ru (FIG. 5).

  From the crop name to the growth stage are parameters that constitute conditions (growth state conditions) for the growth state information in the environmental rule Re.

  A set of a measurement target and a measurement state is a parameter constituting a condition (environmental condition) for environmental information in the environmental rule Re. The measurement target is a target (temperature, precipitation, humidity, etc.) to be measured by a measuring device. The measurement state is a measurement value to be measured or a processing result of the measurement value.

  Note that the environment rule Re in FIG. 17 includes two sets of measurement targets and measurement states. Thus, the environmental rule Re can also include two or more sets of measurement targets and measurement states. When a plurality of sets of measurement objects and measurement states are included, whether or not the environmental condition is satisfied is evaluated by a logical product (AND) of each set.

  In step S403, an environment rule Re that matches the crop name to the growth stage with respect to the growth state information and matches the measurement target and the measurement state with respect to the environment information is searched.

  If the corresponding environment rule Re is not searched (NO in S404), the process in FIG. 16 ends. When the corresponding environmental rule Re is searched (YES in S404), the work rule extraction unit 115 records the searched environmental rule Re in the extraction rule storage unit 116 (S405). That is, the environmental rule Re is extracted as an application candidate.

  Next, a process for extracting work rules according to alarm information will be described. FIG. 18 is a flowchart for explaining an example of a processing procedure of work rule extraction processing according to alarm information. The process of FIG. 18 is executed periodically, for example.

  In step S <b> 501, the work rule extraction unit 115 acquires alarm information from the auxiliary storage device 102. The warning information refers to various types of warning information (for example, typhoon information, pest occurrence prediction information, etc.) provided irregularly by a weather information service company or an agricultural test station. For example, the alarm information is recorded in the auxiliary storage device 102 in accordance with provision from the provider. Recording in the auxiliary storage device 102 may be performed automatically by connecting the provider and the farm work support apparatus 10 via a network, or may be performed by manual input.

  Subsequently, the work rule extraction unit 115 acquires the growth state information from the growth state storage unit 111 (S502). In addition, the process procedure after step S502 is performed about each growth state information memorize | stored in the growth state memory | storage part 111. FIG. However, here, for the sake of convenience, description will be given focusing on one piece of growth state information.

  Subsequently, the work rule extraction unit 115 searches the work rule storage unit 114 for an alarm rule Rw including a condition that matches the growth state information and the alarm information (S503).

  FIG. 19 is a diagram illustrating a configuration example of an alarm rule. The warning rule Rw is a work rule that defines conditions for the crop growth state and warning information, and work to be performed when the conditions are satisfied. In the figure, the warning rule Rw is a rule ID, registration source, crop name, variety, cropping type, cultivation method, growth stage, warning content, measurement state, candidate work, rule target, target achievement confirmation method, and contribution degree. Etc. The rule ID, registration source, registration date, and the like are as described for the growth state update rule Ru (FIG. 5).

  From the crop name to the growth stage is a parameter constituting a condition (growth state condition) for the growth state information in the alarm rule Rw.

  The alarm content is a parameter constituting a condition (alarm condition) for alarm information in the alarm rule Rw. The alarm content is the content of alarm information.

  In step S503, an alarm rule Rw that matches the crop name to the growth stage with respect to the growth state information and the alarm content with respect to the alarm information is searched.

  If the corresponding alarm rule Rw is not searched (NO in S504), the process in FIG. 18 ends. When the corresponding alarm rule Rw is searched (YES in S504), the work rule extraction unit 115 records the searched alarm rule Rw in the extraction rule storage unit 116 (S505). That is, the alarm rule Rw is extracted as an application candidate.

  The extraction rule storage unit 116 performs various factors (growth state) in the predetermined period (for example, one day) by executing the processes of FIGS. , Observation, environment, alarm, etc.), one or more work rules extracted according to the recording state are recorded.

  Next, a processing procedure for outputting a work instruction based on the work rules recorded in the extraction rule storage unit 116 will be described.

  FIG. 20 is a flowchart for explaining an example of a processing procedure of work instruction output processing. The process in FIG. 20 is executed periodically, for example.

  In step S <b> 601, the work instruction unit 117 checks whether a work rule is recorded in the extraction rule storage unit 116. If no work rule is recorded (NO in S601), the process in FIG. 20 ends. Therefore, in this case, no work instruction is output.

  When the work rule is recorded in the extraction rule storage unit 116 (YES in S601), the work instruction unit 117 checks whether or not a plurality of work rules are recorded in the extraction rule storage unit 116 (S602). When there is one work rule recorded in the extraction rule storage unit 116 (NO in S602), the work instruction unit 117 selects the work rule as an application target (S603), and the process proceeds to step S606.

  On the other hand, when a plurality of work rules are recorded in the extraction rule storage unit 116 (YES in S602), the work instruction unit 117 sets the plurality of work rules in descending order based on the contributions included in each. Sorting is performed (S604). Subsequently, the work instruction unit 117 selects a predetermined upper number (for example, one) of work rules as an application target in the sort order (S605). That is, a work rule with a large contribution is preferentially selected. In addition, what is necessary is just to determine a predetermined number suitably according to the number of workers etc. as the number of work which can be performed in one day.

  Some operations are in an exclusive relationship. That is, there can be a relationship such that the effects of both of operations A and B cannot be obtained sufficiently. In such a case, for example, a correspondence table between operations may be created in the auxiliary storage device 102 and the presence / absence of an exclusive relationship may be recorded in the correspondence table. When the work instruction unit 117 selects a plurality of work rules, the work instruction unit 117 determines whether or not there is an exclusive relationship between candidate work of each work rule with reference to the correspondence table. When there is an exclusive relationship, the work instruction unit 117 excludes the work rule related to the exclusive relationship with the lower contribution from the application target. In order to make up for the excluded portion, a work rule that was not initially selected may be moved up and selected.

  Subsequently, the work instruction unit 117 creates a new record that includes the cultivation ID, field ID, crop name, cropping type, cultivation method, growth stage, candidate work, and rule ID of the work rule selected in step S603 or step S605. Is recorded in the work history storage unit 119 (S606). The candidate work is recorded as the work name of a newly recorded record. Regarding the record, the work date and the rule target achievement evaluation value are not recorded at this time. Therefore, the work date is recorded, and the unexecuted work can be determined based on the record. In addition, based on a record in which no rule target achievement evaluation value is recorded, it is possible to determine a work rule in which the degree of achievement with respect to the target is not evaluated.

  Subsequently, the work instruction unit 117 causes the display device 106 to output (display) a screen including the candidate work of the work rule selected in step S603 or step S605, the rule target, and the target achievement level confirmation method (S607). That is, a work instruction is issued, and the worker is shown how to confirm the goal related to the work and the degree of achievement of the goal.

  Next, a description will be given of a processing procedure executed when an operation result is input by an operator who has performed an operation in accordance with an operation instruction based on an operation rule.

  FIG. 21 is a flowchart for explaining an example of a processing procedure of work performance input processing. The process shown in FIG. 5 is executed after the worker performs the work. The processing shown in the figure may be performed collectively for one day's work.

  In step S701, the work record input unit 118 accepts a work record input request. The input request may be made using a known GUI (Graphical User Interface) such as clicking a predetermined icon.

  Subsequently, the work record input unit 118 searches the work history storage unit 119 for a record in which no work date is recorded (S702). Subsequently, the work result input unit 118 causes the display device 106 to display an unworked list screen including a list of retrieved records (S703). Here, it is desirable to display the crop name, cropping type, cultivation method, growth stage, work name, etc. for each record so that the correspondence between each record and the work can be easily identified for the operator.

  Subsequently, the work result input unit 118 receives an input of a work day regarding a record corresponding to the work performed by the worker among the records displayed on the unworked list screen (S704). For example, the work date may be input in the row related to the record on the unworked list screen. Or according to selection of the said line, the work performance input part 118 may display a work day input screen, and a work day may be input via a work day input screen. Furthermore, when the operation of FIG. 21 is thoroughly performed on the day when the work is performed, the work result input unit is set according to a predetermined operation (for example, double-clicking) on a line in the unworked list screen. 118 may automatically determine the date of the day as the work day.

  Subsequently, the work record input unit 118 records the input work date with respect to the record to be input (S705).

  In addition, regarding the rule target that can evaluate the achievement level immediately by performing the work, the rule target achievement evaluation value may be input together with the work date in step S704. In this case, in step S705, the rule target achievement evaluation value is recorded together with the work date. As an example of the rule target that can evaluate the achievement level immediately, for example, the rule target in the growth state rule Rs in FIG. 13 or the observation rule Ro in FIG. The former is “can be planted straight without tilting with respect to the cocoon” with regard to “fixed planting” of the candidate work. The latter is “spreading uniformly so as not to cover the leaves” regarding “topdressing” of the candidate work. These rule goals can be evaluated for their achievement when the work is finished.

  The rule goal achievement evaluation value is determined by the worker according to the rule goal achievement level confirmation method output at the time of the work instruction. Alternatively, it may be determined by a third party such as a supervisor of the worker. In the present embodiment, the rule target achievement evaluation value is input in 100-level evaluation from 0 to 100. In the present embodiment, the range of the stage target achievement evaluation value is also 0 to 100.

  However, depending on the rule target, it is difficult to evaluate the degree of achievement until a few days have passed since the work was performed. For example, the environmental rule Re in FIG. 17 has a rule target of “suppressing the occurrence of illness in the entire field” regarding the candidate work “pesticidal application”. In addition, the alarm rule Rw in FIG. 19 has a rule target of “reducing the amount of generation of diamondback moths in the entire field” regarding “pesticidal application” of the candidate work. It is difficult to evaluate the achievement level of these rule goals immediately after work. Therefore, a rule target achievement evaluation value input process as shown in FIG. 22 is separately performed for a rule for which it is difficult to evaluate the achievement level at the same time as the completion of the work.

  FIG. 22 is a flowchart for explaining an example of the processing procedure of the rule target achievement evaluation value input processing.

  In step S801, the rule target achievement level input unit 120 accepts an input request for the rule target achievement level. The input request may be made using a known GUI (Graphical User Interface) such as clicking a predetermined icon.

  Subsequently, the rule goal achievement level input unit 120 searches the work history storage unit 119 for a record in which the work date is recorded but the rule goal achievement evaluation value is not recorded (S802). Subsequently, the rule goal achievement level input unit 120 causes the display device 106 to display an unevaluated work list screen including a list of retrieved records (S803). Here, it is desirable to display the crop name, cropping type, cultivation method, growth stage, work name, etc. for each record so that the correspondence between each record and the work can be easily identified for the operator.

  Subsequently, the rule goal achievement level input unit 120 receives an input of the rule goal achievement evaluation value for a record for which the rule goal achievement level has been evaluated among the records displayed on the unevaluated work list screen (S804). . For example, the rule target achievement evaluation value may be input in the row related to the record in the unevaluated work list screen. Alternatively, the rule target achievement evaluation value input unit 120 may display a rule target achievement evaluation value input screen according to selection of the row, and the rule target achievement evaluation value may be input via the rule target achievement evaluation value input screen. .

  Subsequently, the rule goal achievement level input unit 120 records the inputted rule goal achievement evaluation value for the record that is the input target (S805).

  By repeating the process described above for each cultivation, the work history storage unit 119 and the growth stage history storage unit 122 are in a state where information recorded by past cultivation is accumulated. Subsequently, by using the work history storage unit 119 and the growth stage history storage unit 122, the degree of contribution of each work rule (the degree of contribution to the stage target of the growth stage to which the work rule is applied) is calculated. Processing will be described.

  First, the contribution level will be reorganized. In the present embodiment, the work rules can be arbitrarily registered by each worker or the like. By doing so, the knowledge possessed or obtained by each worker is collected in the farm work support apparatus 10. As a result, the farm work support apparatus 10 can output an appropriate work instruction based on the knowledge provided by each worker.

  However, some work rules are registered based on information that is generally popular, such as the Internet and literature. That is, some work rules are registered on the basis of an empirical rule that is considered to be valid as a general theory. Therefore, it is not necessarily certain whether all work rules are valid for a particular field.

  Therefore, in this embodiment, each work rule has introduced a contribution as an index for evaluating the actual effectiveness of the crop growth in a specific field (that is, the field to which this embodiment is applied). . This is because the effectiveness of the work rule for the growth of the crop can be evaluated by the contribution of the work rule to the growth of the crop. Each work rule should be set to achieve the stage target of the growth stage to which each work rule is applied. In other words, the execution of the work in accordance with each work rule should be consolidated into the achievement of the stage target of the growth stage in which the work is performed. Then, it is considered that it is appropriate to define the contribution degree of the work rule as a contribution degree to the stage target of the growth stage.

  FIG. 23 is a diagram illustrating an example of a relationship between work rules and stage targets. In the figure, as the growth stage, a seedling raising period, a fixed planting period, a growing period, and the like are illustrated. The stage goal for the seedling season is stage goal A. The work rules set for the seedling raising period are work rule a1 to work rule a3. In addition, the stage target for the fixed planting period is stage target B. The work rules set for the fixed planting period are work rules b1 to b3. The stage target for the growing season is stage target C. The work rules set for the growing season are work rules c1 to c3.

  In the case of the figure, the work rules a1 to a3 should contribute to the achievement of the stage target A. Further, the work rules b1 to b3 should contribute to the achievement of the stage target B. Furthermore, the work rules c1 to c3 should contribute to the achievement of the stage target C.

  Note that the contribution here means the contribution of work performed in accordance with the work rules. However, it is the determination result based on the conditions in the work rules that cause the work to be performed. That is, the effectiveness of the work performed based on the work rule may differ depending on whether or not the condition setting in the work rule is appropriate. Therefore, it can be said that the contribution here is the contribution of the entire work rule.

  Hereinafter, the calculation process of such contribution will be described in detail. FIG. 24 is a flowchart for explaining an example of a processing procedure of work rule contribution calculation processing. In addition, the process of the same figure is automatically performed when a stage target achievement evaluation value is recorded regarding multiple times (predetermined number) cultivation of the same crop. The predetermined number of times may be ideally large, but for example, the process of FIG. Alternatively, it may be executed in response to an instruction input by the user.

  In step S <b> 901, the contribution degree calculation unit 123 acquires one work rule to be processed from the work rule storage unit 114. The processing in FIG. 24 is executed in order for each work rule recorded in the work rule storage unit 114. However, the order acquired in step S901 is not limited to a predetermined one. Hereinafter, the work rule to be processed is referred to as a “current work rule”.

  Subsequently, the contribution calculation unit 123 selects a contribution evaluation range (S902). Specifically, it is selected whether to calculate a contribution level related to a specific field (field ID) or to calculate a contribution level that does not limit the field (field ID). The selection may be performed based on setting information set in advance, for example. For example, when the contribution evaluation range is limited to a specific field, the field ID of the field is recorded in the setting information. On the other hand, when the evaluation range of contribution is not limited, it is recorded that nothing is recorded in the setting information or the evaluation range is not limited. Or when the process of FIG. 24 is performed according to a user's instruction | indication, whether the evaluation range of a contribution degree is limited to a specific field, and when limiting to a specific field, the field of the said field The user may select the ID interactively.

  Subsequently, the contribution calculation unit 123 searches (acquires) the rule target achievement evaluation value for the current work rule from the work history storage unit 119 (S903). Specifically, a record including the rule ID of the current work rule is searched. However, when the evaluation range of contribution is limited to a specific field, the records to be searched are limited to those including the field ID of the field. If the current work rule is applied (used) a plurality of times, a plurality of records are extracted.

  Subsequently, the contribution calculation unit 123 determines whether one or more records have been searched (S904). If no rule target value has been searched, that is, if the current work rule has not been applied in the past (NO in S904), the processing related to the current work rule ends.

  On the other hand, when a record is searched (YES in S904), the contribution calculation unit 123 searches the stage history storage unit for a record that matches the cultivation ID and the growth stage with any record searched in step S903. (S905). Subsequently, the contribution calculation unit 123 determines whether one or more records have been searched (S904). If no rule target value has been searched (NO in S906), the process relating to the current work rule is terminated.

  On the other hand, when a record is searched (YES in S906), the contribution calculation unit 123 includes a set of rule goal achievement evaluation values included in the record searched from the work history storage unit 119 in step S903, and a step A correlation coefficient is calculated based on the set of stage target achievement evaluation values included in the record retrieved from the stage history storage unit in S905 (S907).

  Specifically, when the set of rule target achievement evaluation values is x and the set of stage target achievement evaluation values is y, the following calculation is performed.

  First, a standard deviation S (x) with respect to x is calculated. Subsequently, a standard deviation S (y) with respect to y is calculated. Subsequently, the shared distribution S (x, y) of x and y is calculated by the following calculation.

  S (x, y) = average deviation value = (S (x) × n + S (y) × m) / (n + m)

  Here, n is the number of elements of x. m is the number of elements of y.

  Subsequently, the correlation coefficient r (x, y) is calculated by the following calculation.

  r (x, y) = S (x, y) / (S (x) × S (y))

  For example, x is a set of rule target achievement evaluation values for the work rule X, and y is a set of stage target achievement evaluation values for a certain growth stage Y. In this case, the correlation coefficient between the rule target achievement evaluation value of rule X and the stage target achievement evaluation value of growth stage Y is r (x, y). Assuming that the higher the respective values of x and y, the higher the achievement level, the closer the correlation coefficient r (x, y) is to 1 (that is, the greater the positive correlation is), the rule X is the stage target of stage Y. It can be said that it has greatly contributed to the achievement of.

  Subsequently, the contribution degree calculation unit 123 overwrites the calculated correlation coefficient r (x, y) with the contribution degree of the current work rule (S908). Therefore, when the contribution is already recorded in the current work rule, the contribution is updated with a new value. On the other hand, when no contribution is recorded in the current rule, the correlation coefficient r (x, y) is recorded as the contribution.

  The steps S901 to S908 described above are executed for all the work rules recorded in the work rule storage unit 114, whereby the contribution of each work rule is updated.

  The correlation coefficient is an example. Therefore, the stage goal achievement evaluation value and the rule goal achievement evaluation value may be evaluated by other chronological indicators.

  As described above, according to the present embodiment, it is possible to instruct an operator to perform an appropriate operation at an appropriate time in consideration of not only the growing state of the crop but also the circumstances and environmental conditions peculiar to the field. it can. For example, on-site observation information (such as the occurrence of pests) regarding crops, soil, etc., environmental information (such as temperature, solar radiation, humidity, precipitation, etc.) regarding the field and its surroundings, and various alarm information (for example, Appropriate work instructions are output in accordance with input information indicating various situations occurring in the field and its surroundings, such as typhoon information and pest occurrence prediction information.

  When a plurality of work rules compete, the work rules to be applied are selected (limited) based on the contribution degree of the work rules. Here, the contribution degree is a degree of contribution of a work rule relating to crop growth (that is, relating to achievement of a stage goal) calculated based on past results. Therefore, by selecting the work rule based on the contribution degree, it is possible to increase the possibility that the work that is highly likely to contribute to the growth of the crop (that is, achievement of the stage goal) is performed.

  In the present embodiment, the growth state information is not only mechanically updated with the passage of time, but also based on the growth state update rule Ru and the observation rule Ro. It is updated to the value according to. Here, the growth state information is one piece of input information for determining which work rule should be applied. Therefore, by maintaining a value approximate to the actual crop state for the growth state information, it is possible to improve the accuracy of selection of work rules based on the growth state information.

  In the present embodiment, an example in which a work rule is selected based on a contribution when a plurality of work rules compete is described. However, the work rule may be selected based on other factors. For example, a priority may be set in advance for each work rule registration source. Specifically, priorities are set for registrants, documents, URLs (Uniform Resource Locators) and the like that can be registration sources. In this case, the work rule to be applied is selected based on the priority of each work rule with respect to the registration source. A priority may be set for the type of work rule. For example, when the priority order of alarm rule Rw> observation rule Ro> environment rule Re> growth state rule Rs is set, work according to the alarm or observation result can be prioritized.

  In addition, when the work rules cannot be limited only by the contributions (that is, when the contributions of the extracted work rules are the same), the above selection methods may be combined.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to such specific embodiment, In the range of the summary of this invention described in the claim, various deformation | transformation・ Change is possible.
