1. FIG. 1 is a schematic diagram for explaining an outline of an agricultural management system 1. The agricultural management system 1 includes a sensor terminal 2 installed for each of a plurality of fields, a sensor base station 3 that transmits environment information of each field transmitted from each sensor terminal 2 to the server 5, and environment information of each field. It has the server 5 to manage, and the portable terminal 4 which each user who manages each of several agricultural fields owns.

The agricultural management system 1 executes accumulation or management of environmental information of a farm field or the like in accordance with a request from a user who operates a farm field on which agricultural products are grown. Environmental information includes measured air temperature, humidity, soil temperature, soil moisture content, solar radiation, soil electrical conductivity, soil pH, wind direction and speed, saturation, dew point temperature, water level, water temperature, and CO ₂ etc. This data shows environmental factors.

  One or a plurality of sensor terminals 2 are installed for each of a plurality of fields, and each sensor terminal 2 has a sensor unit for measuring an environmental factor. The sensor base station 3 is installed in each agricultural field, accumulates environment information transmitted from one or a plurality of sensor terminals 2, and transmits the accumulated environment information to the server 5. The mobile terminal 4 is a multi-function mobile phone (so-called “smart phone”), but a mobile information terminal (Personal Digital Assistant, PDA), a portable game machine, a portable music player, a tablet PC, a mobile phone (so-called “feature phone”). Etc.

First, the sensor unit connected to the sensor terminal 2 is the temperature, humidity, soil temperature, soil moisture content, solar radiation, soil electrical conductivity, soil pH, wind direction and wind speed, saturation, dew point temperature, water level in the field A. Measure environmental factors such as water temperature and CO ₂ (1). Next, the sensor terminal 2 acquires and accumulates environmental information indicating environmental factors of the field measured by the sensor unit from the sensor unit at a predetermined measurement cycle. The predetermined measurement period is, for example, 5 seconds, but may be arbitrarily set by a user who operates the farm A or an administrator of the agricultural management system 1. Hereinafter, the environmental information that the sensor terminal 2 earns and accumulates will be described as the soil temperature information measured by the soil temperature sensor.

  Next, the sensor terminal 2 transmits the accumulated soil temperature information to the sensor base station 3 at a predetermined transmission cycle. The predetermined transmission cycle is a value obtained by multiplying the measurement cycle by the number of sensor terminals 2 connected to the sensor base station 3. For example, the sensor terminal 2 connected to the sensor base station 3 with a measurement cycle of 5 seconds. When the number of is 24, the transmission cycle is 120 seconds. The sensor terminal 2 may directly transmit soil temperature information to the server 5 at a predetermined cycle.

  Next, the sensor base station 3 receives the soil temperature information transmitted from the one or more sensor terminals 2 at a predetermined transmission cycle, accumulates the received soil temperature information, and stores the accumulated soil temperature of each sensor terminal 2. The temperature information is transmitted to the server 5 at a predetermined server transmission cycle (2).

In addition, the sensor part provided in the sensor base station 3 may measure soil temperature information, and the sensor base station 3 may transmit the measured soil temperature information to the server 5 with a predetermined server transmission cycle.

  Next, the server 5 receives the current soil temperature information of the field A transmitted. In each of the plurality of fields, the server 5 stores an evaluation value indicating the result value of the crop harvested in the past in each field and the soil temperature information in the growing period in which the crop is grown. The result value is a plurality of evaluation values (evaluation value 1 to evaluation value 5) according to the harvested amount of the harvested crop and a plurality of evaluation values (evaluation value 1 to evaluation value 5) according to the quality of the harvested crop. Indicated by either or both. In the following description, it is assumed that the larger the harvest amount, the larger the evaluation value, and the higher the quality, the larger the evaluation value. In addition, the evaluation value indicating the result value is set by a user (a field manager) who harvests the crop or a specific evaluator.

  In the server 5, range information of soil temperature information is set as a range of measured values of the soil temperature necessary for harvesting the crop having the result value indicated by each evaluation value. For example, the server 5 stores information indicating a range of 23 degrees or more and less than 24 degrees as the range information of the soil temperature information in association with the evaluation value 4 so that a specific crop having the result value of the evaluation value 5 is harvested. To do. Further, the server 5 collects information indicating a range of 20 degrees or more and less than 23 degrees and 24 degrees or more and less than 28 degrees as the range information of the soil temperature information in order to harvest a specific crop having the result value of the evaluation value 4. It is stored in association with the evaluation value 4. Further, the server 5 collects information indicating a range of 17 degrees or more and less than 20 degrees and 28 degrees or more and less than 32 degrees as the range information of the soil temperature information in order to harvest a specific crop having the result value of the evaluation value 3. It is stored in association with the evaluation value 3.

  Based on the received current soil temperature information, the server 5 sets environmental suitability information indicating the soil temperature necessary for harvesting the crops having the evaluation values 4 and 5 (evaluation value 4 or more) in the field A. (3). First, the server 5 compares the current soil temperature information with the range information (range of 20 degrees or more and less than 23 degrees and 24 degrees or more and less than 28 degrees) of the soil temperature information for harvesting the crop with the evaluation value 4. . Then, the server 5 sets environment suitability information for conforming to the range information of the soil temperature information for harvesting the crop with the evaluation value 4 from the current soil temperature information. For example, the case where the current soil temperature information is information indicating 14 degrees will be described. Since the range information of the soil temperature information for harvesting the crop with the evaluation value 4 is information indicating a range of 20 degrees to less than 23 degrees and 24 degrees to less than 28 degrees, the crop with the evaluation value 4 or more is harvested. Therefore, the range information of the soil temperature information is information indicating a range of 20 degrees or more and less than 28 degrees. The environmental compatibility information is information including 6 degrees (20 degrees to 14 degrees) of the difference between the range information of the soil temperature information for harvesting crops with an evaluation value of 4 or more and the current soil temperature information.

  Next, the server 5 transmits the environmental suitability information of the soil temperature in the set field A to the mobile terminal 4 of the user who operates the field A (4). Next, the portable terminal 4 of the user who operates the farm A receives the environmental suitability information of the soil temperature transmitted from the server 5, and displays the received environmental suitability information of the soil temperature (5). And the user who operates the farm A manages the farm A according to the environmental suitability information of the displayed soil temperature.

  Next, the specifying unit 538 selects environment information having a large influence on the evaluation value from the plurality of environment information histories D (step S904). First, the specifying unit 538 performs principal component analysis using environment information in the plurality of environment information histories D as a variable, and calculates a principal component load amount (factor load amount) of each variable in the first principal component. Then, the specifying unit 538 selects a variable (environment information) whose principal component load amount is larger than a predetermined value. Note that the specifying unit 538 may select not only the principal component load amount of the first principal component but also a variable in which each principal component load amount of the second principal component is larger than a predetermined value. When the contribution ratio of the first principal component is lower than a certain value, the range information update process may be terminated without executing the subsequent steps S905 to S907. Further, when there are few types of environment information in the environment information history D (for example, there are three or less types of environment information), the process may be advanced to step S905 without executing step S904.

  Next, the specifying unit 538 determines whether or not there is a specific correlation between the evaluation value in the selected environment information history D and the environment information (step S905). Hereinafter, the correlation between the evaluation value and the environmental information will be described.

  FIG. 17 is a schematic diagram in which the environment information history D is mapped onto a two-dimensional plane with the evaluation value and the environment information as axes. The environmental information shown in FIG. 17 is an integrated value of soil temperature, but may be an integrated value of other environmental factors (such as temperature and solar radiation). In general, it is known that in order to harvest a crop with a high evaluation value, it is necessary to grow the crop within the range of optimum environmental information in each growing season. For example, as shown in FIG. 17, crops with high evaluation values are harvested at an accumulated soil temperature of around 2,300 degrees. As the accumulated soil temperature decreases from 2,300 degrees, crops with a low evaluation value are harvested, and as the accumulated soil temperature increases from 2,300 degrees, a crop with a low evaluation value is harvested.

Here, assuming that the integrated soil temperature is x _i , the evaluation value is y _i, and the average values of x _i and y _i are X and Y, the correlation coefficient R _xy is obtained by the following equation (1). Note that n is the number of data in the environment information history D.

  Moreover, a regression line is calculated | required by following Formula (2).

  In this case, a and b are represented by the following formulas (3) and (4), respectively.

Further, the standard deviation S _e of the estimated value of the evaluation values y is expressed by the following equation (5).

Returning to FIG. 16, in step S905, the identifying unit 538 calculates a regression line indicating a positive correlation between the evaluation value and the environment information and a regression line indicating a negative correlation, and calculates the calculated regression line. When the absolute value of the correlation coefficient R _xy is 0.8 or more, it is determined that there is a specific correlation between the evaluation value and the environment information.

  Next, when the identification unit 538 determines that there is no specific correlation between the evaluation value and the environment information (step S905-No), the process proceeds to step S907.

  On the other hand, when it is determined that there is a specific correlation between the evaluation value and the environment information (step S905-Yes), the specifying unit 538 corresponds to each evaluation value according to the regression line indicating a positive correlation. The lower limit value of the environmental information to be calculated is calculated, and the upper limit value of the environmental information corresponding to each evaluation value is calculated according to the regression line indicating the negative correlation. Next, the specifying unit 538 updates and stores the lower limit value and the upper limit value corresponding to each calculated evaluation value as the range information of the environment information in the range management table stored in the server storage unit 52 (step S906). .

  Next, the screen creation unit 533 creates management screen display data for displaying a management screen including a notification that the range information of the environment information in the range management table has been updated (step S907). Then, the screen creation unit 533 passes the created management screen display data to the server transmission unit 534 and ends the series of steps.

Note that the specifying unit 538 may determine whether or not there is a specific correlation between the first principal component score and the evaluation value in the principal component analysis performed in step S904. First, the specifying unit 538 performs principal component analysis using environment information in the plurality of environment information histories D as a variable, and calculates a first principal component score corresponding to each variable (environment information). In the above-described equation (1), the specifying unit 538 sets the first principal component score to x _i , the evaluation value associated with the variable (environment information) corresponding to the first principal component score as y _i, and x _i And the correlation coefficient R _xy is calculated with the average value of y _i as X and Y. The specifying unit 538 calculates a regression line indicating a positive correlation and a regression line indicating a negative correlation between the evaluation value and the first principal component score by the above-described formulas (2) to (5), When the absolute value of the correlation coefficient R _xy related to the calculated regression line is 0.8 or more, it is determined that there is a specific correlation between the evaluation value and the first principal component score. When the identifying unit 538 determines that there is a specific correlation between the evaluation value and the first principal component score, the first principal component corresponding to each evaluation value according to the regression line indicating the positive correlation A lower limit value of the score is calculated, and an upper limit value of the first principal component score corresponding to each evaluation value is calculated according to the regression line indicating a negative correlation. Next, the specifying unit 538 multiplies the lower limit value and the upper limit value corresponding to each calculated evaluation value by the inverse matrix of the eigenvector calculated by the principal component analysis, and each variable (environment information) selected in step S904. Are updated and stored as range information of each environment information in the range management table stored in the server storage unit 52. This makes it possible to calculate range information for a plurality of environmental information that affects the evaluation value of the harvested crop.

  As described above, the farm management system 1 allows the server 5 to provide farm management information suitable for each field on the basis of the result value of the crops harvested in the past and the history of environmental information. It becomes possible. Therefore, the server 5 can manage an environment suitable for the growth of crops for each field.

  The screen creation unit 533 of the server 5 plots a field environment in which values obtained by integrating the soil temperature and the solar radiation amount of each record stored in the sensor management table are plotted on a two-dimensional plane with the cumulative soil temperature and the solar radiation amount as axes. Display data for displaying a screen including a characteristic curve may be created, and the server transmission unit 534 may transmit the display data to the mobile terminal 4 via the server communication unit 51.

  FIG. 18 is a schematic diagram showing a field environment characteristic curve displayed on a two-dimensional plane with the integrated soil temperature and the integrated solar radiation amount as axes. FIG. 18 shows a field environment characteristic curve in the X test site where a crop with a specific evaluation value 5 is harvested and a field environment characteristic curve in a Y town Z field where the specific crop is grown. Thereby, the discrepancy between the field environment characteristic curve in the current Y town Z field and the field environment characteristic curve in the X test field can be visually recognized.

  By using the field environment characteristic curve, it is possible to determine the optimum species and variety in the current Y town Z field and to analyze the flowering date and the harvest date in a multidimensional manner.

  It should be understood by those skilled in the art that various changes, substitutions and modifications can be made thereto without departing from the spirit and scope of the present invention.
