Description

The present invention relates to an irrigation management system including an imaging unit that images the leaves of a cultivated plant.

As an irrigation system including an imaging unit for imaging the leaves of a cultivated plant, for example, the one described in Patent Document 1 is already known. In this irrigation system, the projected area of the leaves of the cultivated plant is calculated based on the captured image acquired by the imaging unit (“photographing device” in Patent Document 1).

Further, in this irrigation system, the projected area ratio, which is the ratio of the projected area to the maximum projected area, is calculated. Then, when the projected area ratio is less than the liquid supply reference value, irrigation (“supply liquid” in Patent Document 1) is executed for the cultivated plant.

The projected area of the leaf is one of the indexes showing the degree of leaf tension. Therefore, according to this irrigation system, irrigation can be performed according to the degree of leaf tension.

[Structure related to irrigation control]
As shown in FIG. 4, the cultivation system SY in the present embodiment includes a management computer MC and a control panel 54. The management computer MC has a processing unit 4 and a display 53.

The processing unit 4 includes a first coverage rate calculation section 41, a first reference coverage rate setting section 42, a first reference calculation section 43, a first control section 44, a second coverage rate calculation section 45, and a second reference coverage rate setting section. It has 46, a second reference calculation unit 47, and a second control unit 48.

Further, the horticultural facility 1 has a first irrigation device 51 and a second irrigation device 52.

The captured image V acquired by the first camera Ca1 at predetermined time intervals is sent to the first coverage calculation unit 41. The first coverage rate calculation unit 41 calculates the coverage rate Br of the first group GR1 over time based on the received captured image V.

The coverage Br is the ratio of the area occupied by the leaves to the measurement area B (see FIG. 3), which is the area where the leaves are shown in the captured image V. The coverage Br is a value indicating the degree of leaf tension. That is, the coverage Br corresponds to the "tension index value" according to the present invention.

The calculation of the coverage Br will be described in detail. As shown in FIG. 3, the first coverage calculation unit 41 determines the regions of branches and leaves and stems in the captured image V based on the color information of the captured image V and the like. This region is determined as a overgrown region of cultivated plant Q, that is, a covered region.

The determination of the branch / leaf or stem region may be performed based on RGB data or may be performed based on YUV data. However, in the present embodiment, in order to cope with changes in light and darkness due to changes in weather and time zone, it is desirable that the determination of the regions of branches and leaves and stems is performed based on YUV data.

Then, based on the determination of the covering region, the range where the cultivated plant Q is located in the captured image V is set. As shown in FIG. 3, a range surrounded by four sides is set as an area in which the branches and leaves of the cultivated plant Q are reflected, and the range surrounded by these four sides is set as the measurement area B, and the area of the measurement area B is set. Bs is calculated. The area Bs can be calculated by counting the number of dots (minimum unit of pixels in the captured image V) in the measurement area B in the captured image V.

Further, the leaf area B1 can be calculated by counting the number of dots in the covering area. Then, the ratio of the leaf area B1 to the area Bs is calculated as the coverage Br by the following mathematical formula.

Coverage Br = Leaf area B1 / Area Bs

It is desirable that the area Bs of the measurement area B is fixed to the area Bs before the leaves start to wilt even when the leaves are wilted with the passage of time and the area where the branches and leaves are reflected gradually narrows. .. That is, the area Bs is fixed as the area Bs calculated based on the first captured image V among the plurality of captured images V acquired over time, and only the leaf area B1 is fixed with the passage of time. It is desirable to have a configuration that changes.

As shown in FIG. 4, the coverage rate Br calculated over time by the first coverage rate calculation unit 41 is sent to the first reference coverage rate setting unit 42 and the first control unit 44. The first reference coverage setting unit 42 sets the coverage Br of the first group GR1 at the reference time as the reference coverage ST of the first group GR1.

More specifically, in the present embodiment, the above reference time is the time zone immediately after sunrise. Further, as described above, the first camera Ca1 acquires the captured image V at predetermined time intervals. That is, the first camera Ca1 acquires the captured image V at a plurality of times in the time zone immediately after sunrise. As a result, the first camera Ca1 acquires a plurality of captured images V in the time zone immediately after sunrise.

The first coverage calculation unit 41 calculates a plurality of coverage Brs based on the plurality of captured images V acquired in the time zone immediately after sunrise. Then, the first reference coverage setting unit 42 sets the 90th percentile value of the plurality of coverage Br as the reference coverage ST.

The present invention is not limited to this, and even if the first reference coverage setting unit 42 is configured to set a value other than the 90th percentile value of the plurality of coverage Br as the reference coverage ST. good. For example, the first reference coverage setting unit 42 may be configured to set the maximum value among the plurality of coverage Br as the reference coverage ST. Further, the first reference coverage setting unit 42 may be configured to set the average value of the plurality of coverage Br as the reference coverage ST.

As shown in FIG. 4, the reference coverage ST set by the first reference coverage setting unit 42 is sent to the first reference calculation unit 43.

Further, the user can input the wilting coefficient via the control panel 54. The wilting coefficient is a coefficient corresponding to the degree of wilting of the target leaf.

The wilting coefficient input to the control panel 54 is sent to the processing unit 4. Then, the first reference calculation unit 43 has the irrigation reference value of the first group GR1 based on the reference coverage ST received from the first reference coverage setting unit 42 and the wilting coefficient input to the control panel 54. Calculate TH. More specifically, the first reference calculation unit 43 calculates the irrigation reference value TH by multiplying the reference coverage ST by the wilting coefficient. The calculated irrigation reference value TH is sent to the first control unit 44.

The first control unit 44 determines the irrigation reference value TH by the coverage Br based on the coverage Br received from the first coverage calculation unit 41 and the irrigation reference value TH received from the first reference calculation unit 43. Determine if it is below. Then, when the coverage Br falls below the irrigation reference value TH, the first control unit 44 outputs an irrigation instruction signal.

The output irrigation instruction signal is sent to the first irrigation device 51. The first irrigation device 51 executes irrigation to each plant individual Q1 belonging to the first group GR1 in response to the irrigation instruction signal received from the first control unit 44.

That is, when the coverage Br of the first group GR1 is lower than the irrigation reference value TH of the first group GR1, the first control unit 44 causes the first irrigation device 51 to irrigate the first group GR1.

Further, the captured image V acquired by the second camera Ca2 at predetermined time intervals is sent to the second coverage calculation unit 45. Then, the second coverage calculation unit 45, the second reference coverage setting section 46, the second reference calculation section 47, and the second control section 48 are the first coverage calculation section 41 and the first reference coverage section described above. It has the same functions as the setting unit 42, the first reference calculation unit 43, and the first control unit 44.

That is, the second coverage calculation unit 45 calculates the coverage Br of the second group GR2 by performing the same processing as the first coverage calculation unit 41.

Further, the second reference coverage setting unit 46 sets the reference coverage ST of the second group GR2 by performing the same processing as the first reference coverage setting section 42.

Further, the second standard calculation unit 47 calculates the irrigation reference value TH of the second group GR2 by performing the same processing as the first standard calculation unit 43.

Further, the second control unit 48 performs the same treatment as the first control unit 44, and when the coverage Br of the second group GR2 falls below the irrigation reference value TH of the second group GR2, the second group The second irrigation apparatus 52 is made to irrigate the GR2.

Here, as shown in FIG. 4, the first coverage calculation unit 41 and the second coverage calculation unit 45 constitute a coverage calculation unit 40 (corresponding to the “tension index value calculation unit” according to the present invention). ing. The coverage rate calculation unit 40 calculates the coverage rate Br based on the captured image V acquired by the fixed point camera Ca.

More specifically, the coverage ratio calculation unit 40 calculates the coverage ratio Br for each group based on the captured image V acquired by the fixed point camera Ca.

That is, the cultivation system SY includes a coverage rate calculation unit 40 that calculates a coverage rate Br, which is a value indicating the degree of leaf tension, based on the captured image V acquired by the fixed point camera Ca. More specifically, the cultivation system SY has a coverage calculation unit 40 that calculates a coverage Br, which is a value indicating the degree of leaf tension, for each group based on the captured image V acquired by the fixed-point camera Ca. I have.

Further, as shown in FIG. 4, the irrigation device 50 is configured by the first irrigation device 51 and the second irrigation device 52. The irrigation device 50 irrigates the cultivated plant Q.

That is, the cultivation system SY includes an irrigation device 50 for irrigating the cultivated plant Q. Further, irrigation by the irrigation device 50 is performed individually for each group.

Further, as shown in FIG. 4, the irrigation control unit 49 is configured by the first control unit 44 and the second control unit 48. The irrigation control unit 49 controls the irrigation device 50. That is, the cultivation system SY includes an irrigation control unit 49 that controls the irrigation device 50. Then, when the coverage Br falls below the predetermined irrigation reference value TH, the irrigation control unit 49 causes the irrigation device 50 to irrigate the group corresponding to the coverage Br below the irrigation reference value TH.

With the configuration described above, as shown in FIG. 5, the coverage Br of the first group GR1 and the second group GR2 basically changes as follows. That is, first, the wilting of the leaves progresses with the passage of time. As a result, the coverage Br decreases with the passage of time.

When the coverage Br falls below the irrigation reference value TH and irrigation is performed, the degree of leaf tension is restored. As a result, the coverage Br increases.

After that, the progress of leaf wilting with the passage of time and the recovery of leaf tension by irrigation are repeated. As a result, the coverage Br alternately repeats a decrease and an increase.

In the example shown in the upper part of FIG. 5, the timing at which the irrigation instruction signal is output by the first control unit 44 is indicated by an upward arrow. In this example, since the coverage Br was below the irrigation reference value TH at each of time t1, time t2, time t4, and time t6, the irrigation instruction signal was output by the first control unit 44. As a result of irrigation to the first group GR1 as a result, the coverage Br exceeds the irrigation reference value TH.

Further, in the example shown at the lower part of FIG. 5, the timing at which the irrigation instruction signal is output by the second control unit 48 is indicated by an upward arrow. In this example, since the coverage Br was below the irrigation reference value TH at each of the time t3 and the time t5, the irrigation instruction signal was output by the second control unit 48. As a result of irrigation to the second group GR2, the coverage Br exceeds the irrigation reference value TH.

In the example shown in FIG. 5, the wilting coefficient of the second group GR2 is set to a value smaller than the wilting coefficient of the first group GR1 by the user. Therefore, the irrigation reference value TH of the second group GR2 is lower than the irrigation reference value TH of the first group GR1. As a result, the number of times of irrigation to the second group GR2 is less than the number of times of irrigation to the first group GR1.

[Display contents on the management computer]
As shown in FIG. 6, the display 53 of the management computer MC can display the management screen 56. The management screen 56 has a first transition display area 61 and a second transition display area 62. The first transition display area 61 and the second transition display area 62 are vertically adjacent to each other.

The first transition display area 61 is an area for displaying time-series information regarding the first group GR1. Further, the second transition display area 62 is an area for displaying time-series information regarding the second group GR2.

Both the first transition display area 61 and the second transition display area 62 include the graph area 63 and the mode transition display area 64. The mode transition area 64 is displayed in an overlapping state at the lower end of the graph area 63.

The graph area 63 is an area for displaying transition information and irrigation information. The transition information is information indicating the transition of the coverage rate Br. Further, the irrigation information is information indicating the timing at which irrigation is executed by the irrigation device 50.

As shown in FIG. 6, in the graph area 63, a graph 63a showing the correspondence between the time and the coverage rate Br is displayed as the transition information.

That is, the display 53 displays the transition information by the graph 63a showing the correspondence relationship between the time and the coverage rate Br.

Here, the control mode of the irrigation control unit 49 shown in FIG. 4 can be switched between the first irrigation mode and the second irrigation mode by operating the control panel 54. The first irrigation mode is a control mode in which the irrigation device 50 executes irrigation when the first condition is satisfied. Further, the second irrigation mode is a control mode in which the irrigation device 50 executes irrigation when the second condition different from the first condition is satisfied.

In the present embodiment, the first condition is "the coverage Br is below the irrigation reference value TH" or "the period during which the coverage Br is continuously above the irrigation reference value TH reaches the predetermined determination time TR". Is to satisfy any of the above. That is, the first condition includes that the coverage Br is below the predetermined irrigation reference value TH.

Further, in the present embodiment, the second condition is that the current time becomes the set irrigation time, which is the set time. That is, the second condition does not include that the coverage Br falls below the irrigation reference value TH.

With the above configuration, in the control mode of the irrigation control unit 49, the determination time TR is reached when the coverage Br is below the irrigation reference value TH and the period during which the coverage Br is continuously above the irrigation reference value TH. It is possible to switch between the first irrigation mode in which the irrigation device 50 is irrigated and the second irrigation mode in which the irrigation device 50 is irrigated at the set irrigation time, which is the set time.

Further, when the control mode of the irrigation control unit 49 is the first irrigation mode, the irrigation control unit 49 determines when the coverage Br is below the irrigation reference value TH and the coverage Br is continuously the irrigation reference value TH. When the above period reaches the determination time TR, the irrigation device 50 is to be irrigated. That is, in the cultivation system SY, when the coverage Br is below the predetermined irrigation reference value TH, and when the period during which the coverage Br is continuously equal to or higher than the irrigation reference value TH reaches the predetermined determination time TR. The irrigation device 50 is provided with an irrigation control unit 49 for executing irrigation.

Further, the control panel 54 can send an irrigation instruction signal to the irrigation control unit 49 in response to a manual irrigation operation by the user. The irrigation control unit 49 immediately causes the irrigation device 50 to perform irrigation in response to this signal.
