Description

Soil condition evaluation device, corresponding method and corresponding program

The present invention relates to a soil condition evaluating apparatus, a soil condition evaluating method and a soil condition evaluating program for evaluating the state of soil in packaging from the viewpoint of reducing ability.

Because crops are generally grown in the soil, the state of the soil affects the yield and quality of the crop. In particular, due to the influence of global warming in recent years, troubles occur in the crops, and the frequency of damaging the integrity tends to increase. On the other hand, the environment of agricultural management is difficult, and reduction of production cost is demanded. For this reason, it is preferable that the state of the soil is appropriately evaluated and a countermeasure corresponding to the evaluation result is appropriately carried out, and a technique for appropriately evaluating the state of the soil is desired.

Such a technique for evaluating the state of the soil is disclosed in, for example, Patent Document 1. [ The soil analysis method disclosed in Patent Document 1 is a soil analysis method for analyzing a nutrient amount for cultivating various crops in a predetermined soil. The soil analysis method includes a step of cutting a predetermined soil to a predetermined depth and sampling the sample, Treating the treated liquid with a treatment liquid containing strong acid to obtain an extract and chemically analyzing the obtained extract with an ion chromatograph to accurately grasp the amount of the nutrients in the soil.

However, in the soil analysis method disclosed in Patent Document 1, it is considered that the amount of soil in the soil can be analyzed relatively accurately because the sample is actually sampled from the soil and chemically analyzed by the ion chromatograph. [0012] In the paragraph [0012] of the Patent Document 1, "Sampling can be performed at a plurality of places appropriately dispersed so that necessary data collection can be performed from the entire farm to obtain accurate analysis results. However, the four corners and diagonal lines It is preferable that the sampling points be six points of arbitrary two points on the line. &Quot;

On the other hand, in the case of evaluating the so-called reduction failure, the reduction failure causes few cases to occur in the entire package, and many cases occur in some places of the package. For this reason, as in the soil analysis method disclosed in Patent Document 1, if the reduction failure is evaluated by sampling the sample from the soil, sampling must be performed at a plurality of locations throughout the entire package, resulting in a lot of work and inefficiency. Sampling the sample from the soil in the first place is very handy in itself.

In the drawings, the same reference numerals denote the same components, and a description thereof will be omitted. In this specification, suffixes are denoted by the same reference numerals in the case of generic terms, and denoted by reference numerals with suffixes denoting individual constructions.

(Correlation)

First, the correlation between the degree of reductivity in packaging and the temperature of the crop will be described based on one experimental example.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view for explaining the correlation between the occurrence of reduction failure in packaging and the temperature of a crop. Fig. Fig. 1A is a diagram showing a thermal distribution image of a faucet, and Fig. 1B is a diagram showing an average value of the number of teeth in rice grown in the faucet. The faucet of the test subject is a lime N sphere shown on the left side of the ground, which is a region where 20 kg of lime nitrogen is supplied per 10 arcs (a) as a material for improving the reduction trouble, Respectively. Before these lime N sphere and control, the water is drawn from the "water inlet" above the ground and flows from above the ground to the bottom of the ground and drained from the "water bottom". Each of the lime N sphere and the control is divided into three regions in the region and in the horizontal direction of the ground, and six regions in the vertical direction of the ground, and is divided into sub regions of 3 × 6 = 18. The average value of the number of ears of the rice is, and the numerical average of the ears of rice to be grown in one sub-region, is shown in Figure 1b with at / m ² unit. In the heat distribution distribution image shown in Fig. 1A, it is shown that the darker the color in gray scale, the higher the heat radiation from the water supply, in other words, the temperature of the water supply, or in other words, the temperature of rice. The temperature of the ambient environment of the aquifer when picking up the heat distribution image of the aquatic power shown in Fig. 1A was 31.2 占 폚.

In Fig. 1B, in the control on the right side of the paper, there are nine sub-regions having an average value of 400 pcs / m ² of the number of rice spikes, eight subspaces having an average value of 500 pcs / m ^{2 of the} number of rice spikes , There is 1 sub region in which the mean number of the rice number is 600 / m ² , while in the lime N region on the left side of the ground, there are ² sub regions in which the average number of rice number is 400 / m ² , Isaacs number average value is 4 to 500 / m ² delivery sub-region of one, the average number of ears of rice 600 / m ² the delivery sub-region 12 atoms. Therefore, in the lime N region, the degree of reduction is small in most areas due to the material of the calcareous material, and the occurrence of reduction trouble is suppressed, and as a result, the rice grows smoothly. On the other hand, as for the control, on the contrary, the degree of reductivity increases in some places, and reduction trouble occurs in the above places, and the growth of rice is not smooth. In the control group, especially in the nine sub-areas shown by surrounding by ○ in Figure 1b, the number of ears of rice is 435 / m ² to 498 / m ² by an average of the sub-region, apparently the growth defect by reducing interference .

On the other hand, as seen from the heat distribution image, as shown in Fig. 1A, the number of the sub regions in the lime N sphere having a relatively high heat (high temperature of the storage tank and high temperature of the rice) is smaller than that of the control, (Temperature of the rice) in the control is lower than the temperature of the water-receiving (rice) temperature in the control. In particular, the temperature of the water of the nine sub-regions indicated by the circle in Fig. 1B (rice temperature) is apparently higher than the temperature of the water of the lime N sphere adjacent thereto (rice temperature).

This is because, in the lime N sphere, the degree of reduction is small in most areas due to the material of the calcareous material, and the occurrence of reduction trouble is suppressed. As a result, the rice grows smoothly and the temperature is relatively high , It was considered that the water was transported to the entire rice and the amount of the evaporation from the pores became smooth. Therefore, it was considered that the water temperature (rice temperature) was lowered. On the other hand, If the temperature is lower than 31.2 ° C., the moisture is not transported to the entire rice and the amount of evaporation from the pores is reduced. Therefore, (Temperature of rice) is increased.

Thus, a correlation is confirmed between the degree of reduction in packaging and the temperature of the crop.

Therefore, each pixel of the temperature distribution image Tarp of this package represents the temperature (Tar) of the package at the pixel position. The packaging temperature processing unit 122 stores the obtained temperature distribution image Tarp in correspondence with the position Pap and the temperature Ts corresponding to the thermal distribution image SP of the package, (132).

The soil condition evaluation unit 123 calculates the soil temperature based on the temperature distribution image Tarp of the package obtained by the packaging temperature processing unit 122 and the temperature Ts of the package received by the communication IF unit 11, (EV) of the package in multiple stages. More specifically, the soil condition evaluation unit 123 uses the evaluation value conversion information stored in the conversion information storage unit 136 to calculate the temperature distribution image Tarp of the package and the temperature Ts of the package, To the evaluation value (EV). In this embodiment, the soil condition evaluation unit 123 calculates the temperature distribution image (Tarp) of the package in the sub region (SAR) of a predetermined width set in advance The representative value of the temperature Tar is obtained for each of the subareas SAR and the difference between the obtained temperature of the representative value Tar and the temperature Ts of the package is obtained. (EV) using conversion information. In one thermal distribution image SP, that is, one temperature distribution image Tarp corresponding thereto, the temperature Ts of the package is considered to be the same throughout the package (in each sub-area SAR) do. Thus, the reductive evaluation map EVm to which the evaluation value EV (SAR) is given for each sub-region SAR is produced. The sub region SAR may be any shape (for example, a triangle, a square, a hexagon, etc.) and may have an arbitrary width (0.5 arrays, 1 ars, 2 ares, etc.) For example, it is a square of 5m or 10m on one side. The representative value may be, for example, an average value of all the pixels in the sub region SAR, and may be a median value of the sub region SAR, for example. The soil reductivity evaluating unit 123 then compares the obtained reductive evaluation map EVm with the position Pap corresponding to the temperature distribution image Tarp of the package and the temperature Ts of the package, And stores it in the information storage unit 133. [

Here, in the present embodiment, the soil reductivity evaluating unit 123 judges that the evaluation condition accepted by the communication IF unit 11 or the input unit 14 meets the setting evaluation condition stored in the setting evaluation condition information storage unit 135 , The evaluation value EV obtained as described above is obtained as the final evaluation value EV. More specifically, the soil reductivity evaluating unit 123 evaluates the evaluation value (EV) when the temperature Ts of the package received by the communication IF unit 11 is equal to or higher than the predetermined temperature Th (EV). In the present embodiment, the soil reductivity evaluating unit 123 evaluates whether or not the thermal distribution image SP of the package is a clear or clear sky and is picked up at any time from 9 o'clock to 15 o'clock, The value EV is used as the final evaluation value EV.

The magnetic characteristic amount processing section 124 obtains the amount of material (MV) for improving the reducing property based on the evaluation value (EV) obtained by the soil reductive evaluation section 123. More specifically, the resource amount calculating unit 124 uses the resource amount conversion information stored in the conversion information storing unit 136 to calculate the resource amount of the reductive evaluation map EVm stored in the reductive evaluation information storing unit 133 And converts each evaluation value EV (SAR) associated with each subregion SAR into a characterization amount MV (SAR). Thus, the resource amount map MVm to which the resource amount MV (SAR) is assigned for each sub region SAR is produced. The resource amount processing unit 124 stores the obtained resource amount map MVm in the resource amount information storage unit 134 in correspondence with the position Pap corresponding to the reductive evaluation map EVm of the package do.

Next, the operation of the soil condition evaluation system S (thermal distribution image generation device M and soil condition evaluation device P) in the present embodiment will be described. 4 is a flowchart showing the operation of the soil condition evaluation apparatus of the soil condition evaluation system. 5 is a schematic diagram showing a temperature distribution image of a package as an example. Fig. 6 is a view showing an evaluation value map obtained based on the temperature distribution image of the package schematically shown in Fig. 5. Fig. 7 is a diagram showing a resource amount map obtained on the basis of the evaluation value map shown in Fig.

In the soil condition evaluation system (S), first, the heat distribution image generation device (M) and the soil condition evaluation device (P) start initialization of each necessary part and start operation thereof when power is turned on. In the soil condition evaluation apparatus P, the control processing section 12 is provided with a control section 121, a packaging temperature processing section 122, a soil reduction evaluation section 123 and a resource amount processing section 124 ) Are functionally configured.

The thermal distribution image generating device M captures an image of the package AR to be evaluated from above and fires in accordance with the control of the control section 23 by an induced flight or an autonomous flight, And the temperature is measured by the temperature measurement unit 22. [ The thermal distribution image generating apparatus M is configured to generate the positioning result Pap obtained by the GPS 21, the temperature measurement unit 22 and the thermal distribution image generation unit 24, Temperature Ts of the measurement result and the heat distribution image SP (not shown) generated by imaging are transmitted from the communication IF unit 26 to the soil condition evaluation apparatus P by a communication signal.

4, the soil condition evaluation apparatus P calculates the soil temperature Ts from the thermal distribution image generating apparatus M in the communication IF unit 11 (Pap (position (Pap)) and measurement result Ts (Ts) of the package and the thermal distribution image (SP) of the package are received and associated with each other, the acquired position (Pap), the package temperature (Ts) (S11), and obtains the evaluation condition by the control processing unit 12 (S12). This evaluation condition is obtained by accepting the input of the evaluation condition in the input unit 14 after the operation of the soil condition evaluation apparatus P and storing the evaluation condition in the storage unit 13, The evaluation condition may be obtained. Further, for example, the evaluation condition may be evaluated by the input section 14 when the position (Pap), the temperature of the package (Ts) and the thermal distribution image (SP) of the package are obtained from the thermal distribution image generating device The condition input may be received and acquired. The input operation of the evaluation condition may be executed at a predetermined time interval (for example, every 30 minutes, every hour, every two hours, etc.). In the present embodiment, weather and time are input from the input unit 14 as one of the evaluation conditions. On the other hand, the temperature Ts of the package is also received as another evaluation condition in the communication IF unit 11 as described above.

Subsequently, the soil condition evaluation apparatus P obtains the temperature (Tar) of the package based on the thermal distribution image SP of the package by the packaging temperature processing unit 122 of the control processing unit 12, The distribution image Tarp is obtained and stored (S13). More specifically, the packaging temperature processing section 122 uses the above-mentioned temperature conversion information stored in the conversion information storage section 136 to calculate each pixel in the thermal distribution image SP of the package acquired in the processing S11 as (Temperature distribution image) Tarp indicative of the temperature distribution of the package is obtained by converting the temperature to a temperature corresponding to the pixel value. The packaging temperature processing unit 122 stores the obtained temperature distribution image Tarp in the temperature distribution information storage unit 132 in association with the position Pap acquired in the process S11 and the temperature Ts.

Subsequently, the soil condition evaluation apparatus P obtains the evaluation value EV by the soil reductive evaluation unit 123 of the control processing unit 12 (S14). More specifically, the soil reductivity evaluating unit 123 evaluates the soil reductivity (Tarp) of the package obtained by the packaging temperature processing unit 122 in the process S13 and the temperature distribution image (Tarp) of the package obtained in the process S11 Based on the difference, the evaluation value (EV) of the package is obtained in multiple stages. More specifically, the soil reductivity evaluating unit 123 compares the representative value of the temperature Tar of the sub region SAR with respect to each of the plurality of sub regions SAR separated by the package AR from the processing S13 From the temperature distribution image (Tarp) of the package obtained in the conversion information storage unit 136 (Tarp), and obtains the difference DELTA T between the temperature (Tar) of the representative value and the temperature Into the evaluation value EV (SAR) by using the evaluation material conversion information table CT stored in the evaluation material conversion information table CT. Thereby, the reductive evaluation map EVm is created.

Subsequently, the soil condition evaluation apparatus P judges whether or not the received evaluation condition satisfies the setting evaluation condition stored in the setting evaluation condition information storage unit 135 by the soil reversion evaluation unit 123 ( S15). As a result of the judgment, when the evaluation condition satisfies the setting evaluation condition (Yes), the soil reductivity evaluating unit 123 compares the evaluation value EV obtained in the process S14 with the finally obtained evaluation value EV ), And when the evaluation condition does not satisfy the setting evaluation condition ("NO"), the soil reductive evaluation unit 123 judges the evaluation value EV obtained in the process S14 as an error, Value (EV). More specifically, the soil reductivity evaluating unit 123 determines whether or not the temperature Ts of the package obtained in the process S11 is equal to or higher than the predetermined temperature Th and the weather received in the process S12 is a clear or clear sky It is determined whether or not the time of receipt in the process S12 is from 9:00 to 15:00. As a result of the determination, the soil reductivity evaluating section 123 determines that the temperature Ts of the package obtained in the process S11 is equal to or higher than the predetermined temperature Th and the weather received in the process S12 is a clear or clear sky, (YES), the soil reductivity evaluating unit 123 judges that the time at which the acceptance is made in the process S12 is from 9:00 to 15:00, And the evaluation value EV obtained in the above-mentioned evaluation process is finally determined as the evaluated value EV. On the other hand, as a result of the determination, if the temperature Ts of the package obtained in the process S11 is not equal to or higher than the predetermined temperature Th, or the weather received in the process S12 is clear If it is not clear sky, or if the time received in the process S12 is not from 9 o'clock to 15 o'clock (that is, the temperature Ts of the package obtained in the process S11 is not less than the predetermined temperature Th) A case where the received weather is a clear or clear sky and a time when the reception time in the process S12 is from 9:00 to 15:00 is not satisfied), the evaluation condition satisfies the set evaluation condition (NO), the soil reductivity evaluating unit 123 does not make the evaluation value EV finally determined as the error, the evaluation value EV obtained in the process S14.

Subsequently, the soil condition evaluation device P calculates the evaluation value EV (reduction evaluation map EVm in this embodiment) obtained in the process S14 by the soil reductivity evaluation section 123, Is stored in the reducibility evaluation information storage unit 133 (S16) in association with the position (Pap) and the air temperature Ts acquired in the process S11.

Subsequently, the soil condition evaluation apparatus P judges whether or not the soil property evaluating unit P has determined, based on the evaluation value EV obtained by the soil reductivity evaluating unit 123 by the resource amount processing unit 124 of the control processing unit 12, And obtains and stores the character amount MV (S17). More specifically, the resource amount processing unit 124 uses the resource amount conversion information stored in the conversion information storage unit 136 to calculate the resource amount of each region (SAR) of the reductive evaluation map EVm obtained in the process S14 And converts each associated evaluation value EV (SAR) into a character amount MV (SAR). Then, the magnetic resource amount processing section 124 stores the found magnetic resource amount map MVm in the magnetic resource information storage section 134 in association with the position (Pap) acquired in the process S11.

The soil condition evaluation apparatus P then outputs the evaluation value EV and the resource amount MV of the evaluation target package AR from the output unit 15 by the control processing unit 12 S18), and the process ends. More specifically, the control processing unit 12 outputs the reductive evaluation map EVm obtained in the process S14 and the resource amount map MVm in the process S16 from the output unit 15 in accordance with the determination result of the process S15. More specifically, for example, the control processing unit 12 compares the evaluation value EV obtained in the process S14 (the reductive evaluation map EVm in this embodiment) to the finally obtained evaluation value EV, (The reductive evaluation map EVm in this embodiment), the reductive evaluation map EVm obtained in the process S14 and the resource amount map MVm in the process S16 are outputted from the output unit 15, and the control processing unit 12 output the output of the error from the output unit 15 without satisfying the setting evaluation condition when the determination result of the process S15 is an error. If the determination result of the processing S15 is an error, the control processing unit 12 outputs the fact that the error has occurred as an error without satisfying the setting evaluation condition, and also, as reference information, The evaluation map EVm and the resource amount map MVm may be output from the output unit 15 in step S16.

For example, from the thermal distribution image SP in the package AR to be evaluated, the pixel value is converted for each pixel using the temperature conversion information to obtain the temperature distribution image (Fig. 5 Tarp) are obtained by the processing S13. In step S14, a representative value of the temperature Tar of the sub region SAR is obtained for each of the sub regions SAR of the temperature distribution image Tarp shown in Fig. 5, The reductive evaluation map EVm shown in Fig. 6 is obtained by converting the representative value of the temperature Tar using the evaluation material conversion information table CT. In step S17, the evaluation value EV (SAR) of the sub region SAR is compared with the evaluation material conversion information table CT (SAR) for each of the sub regions SAR of the reductive evaluation map EVm shown in Fig. ) To obtain the resource amount map MVm shown in Fig.

The soil condition evaluating device P then obtains the positioning result Pap (position Pap), the temperature Ts of the measurement result (the temperature Ts of the package) The above-described processes S11 to S18 are executed every time a communication signal containing the thermal distribution image SP of FIG. When a plurality of reductive evaluation maps EVm (Par) according to each of the positions Pap are connected by this operation, the plurality of reductive evaluation maps EVm (Par) are connected to the plurality of reductive evaluation maps EVm (Par)) corresponding to each of the plurality of pixels. For example, for each of the plurality of reductive evaluation maps EVm (Par), an image of the thermal distribution image SP corresponding to the position Pap from the imaging direction (optical axis direction) of the thermal distribution image generation unit 24 The position on the reductive evaluation map EVm (Par) corresponding to the angle of view, the position Pap and the position Pap of the heat distribution image generation unit 24 is obtained, (Par)), the position of the peripheral portion of the reductive evaluation map EVm (Par) is obtained. Based on each position of each peripheral portion of each of the reductive evaluation maps EVm (Par) thus obtained, the respective positional relationships of the respective reductive evaluation maps EVm (Par) are obtained, and the respective reductive evaluation maps EVm (Par) Par) is connected. When a plurality of resource amount maps MVm (Par) corresponding to each of the positions Pap are connected to each other, a similar process to that in the case of connecting the plurality of reductive evaluation maps EVm described above, The discretion map MVm (Par) is linked based on each position (Pap) corresponding to each of the plurality of resource amounts maps MVm (Par).

As described above, the soil state evaluation system (S), the soil condition evaluation apparatus (P), the soil condition evaluation method and the soil condition evaluation program in the present embodiment are the same as the thermal distribution image (SP) (EV) indicating the degree of reductivity in the soil of the package (AR) to be evaluated is found based on the temperature (Ts) of the package and the temperature of the package, it is not necessary to sample the sample from the soil, Since the image SP can be obtained in a relatively wide range at once by, for example, a thermal distribution image generation apparatus or the like, the degree of reduction can be more efficiently evaluated.

From the above-described reduction failure process, the greater the difference between the temperature of the package (Tar) and the temperature of the package (Ts), the greater the degree of reductivity. The soil condition evaluation system (S), the soil condition evaluation device (P), the soil condition evaluation method and the soil condition evaluation program are programmed based on the difference (DELTA T) between the temperature (Tar) , The evaluation value EV is obtained in multiple stages, so that an appropriate evaluation value EV can be obtained.

The soil condition evaluation system (S), the soil condition evaluation apparatus (P), the soil condition evaluation method, and the soil condition evaluation program may be configured such that the received evaluation condition is stored in the setting evaluation condition information storage unit 135 ), The final evaluation value EV is obtained, so that a more appropriate evaluation value EV can be obtained.

The soil condition evaluation system (S), the soil condition evaluation device (P), the soil condition evaluation method, and the soil condition evaluation program may be such that the weather is clear or clear sky and the time is from 9:00 to 15:00. Therefore, a more appropriate evaluation value can be obtained in consideration of the above-described reduction failure process.

The soil condition evaluation system (S), the soil condition evaluation device (P), the soil condition evaluation method and the soil condition evaluation program each obtain evaluation values for each of a plurality of sub areas, And the degree of reductivity occurring in various places of the package can be evaluated.

In the past, when reduction failure occurred, the degree of reduction was unclear, and the material was supplied to the entire packaging (AR) in a uniform amount. The soil condition evaluation system (S), the soil condition evaluation device (P), the soil condition evaluation method and the soil condition evaluation program calculate the amount of material (MV) based on the evaluation value (EV) Materials can be supplied to the packaging (AR). As a result, the amount of material (MV) can be reduced as compared with the case where the material is supplied to the package AR in a uniform amount, so that the cost can be reduced and the cost-effectiveness can be improved. Particularly, when the evaluation value EV (SAR) is required for each of the plurality of sub regions SAR, the amount of material MV (SAR) is set for each of the plurality of sub regions SAR The material can be supplied to the individual sub-areas SAR according to the degree of reductivity, so that the material can be supplied to the package AR more efficiently.

Further, in the above-described embodiment, the material amount is obtained regardless of whether or not the setting evaluation condition is satisfied, but the material amount may be obtained only when the setting evaluation condition is satisfied. In other words, when the set evaluation condition is not satisfied, execution of the process S17 for obtaining and storing the resource amount is skipped.

Although the soil condition evaluation apparatus P has acquired the thermal distribution image SP from the thermal distribution image generation apparatus M by wireless communication in the above embodiment, The soil condition evaluating apparatus P is connected to the soil condition evaluating apparatus P via a cable or the like so as to exchange data with each other and the soil condition evaluating apparatus P acquires the heat distribution image SP from the heat distribution image generating apparatus M You can. In this case, the thermal distribution image acquisition unit is an interface unit that receives, from the thermal distribution image generation apparatus M, the thermal distribution image SP in the package to be evaluated by wire. The soil condition evaluation apparatus P may also acquire the thermal distribution image SP through a communication line from a server apparatus that stores and manages the thermal distribution image SP. In this case, the thermal distribution image acquisition unit is configured to receive the thermal distribution image (SP) through the communication line from the server apparatus that stores and manages the thermal distribution image (SP) in the package (AR) Communication interface unit. Further, the soil condition evaluation apparatus P may acquire the thermal distribution image SP from the recording medium on which the thermal distribution image SP is recorded. In this case, the thermal distribution image acquisition unit acquires the thermal distribution image SP from the storage medium on which the thermal distribution image SP in the package AR to be evaluated is recorded, For example, an HDD drive device or a CD-ROM drive device).

The so-called reduction failure is thought to occur by the following process. That is, for example, when hydrogen sulfide or organic acid is generated in the soil in a package such as a faucet or the like, the growth and the activity of the root in the crop such as rice are inhibited, and as a result, the growth of the crop is suppressed, The ability to suck up the moisture of the crop is weakened. For this reason, for example, when the temperature is relatively high in a relatively hot period described below, moisture is not transported to the entire crop and the amount of evaporation from pores is reduced. As a result, for example, the temperature of the crop itself (equivalent to the body temperature in the case of human being) can not be sufficiently lowered as in the case of heat stroke of a human, resulting in poor growth or wrinkling. If such a reduction trouble occurs, the yield of the crop is lowered and the quality thereof is also deteriorated.
