However, in the case of the conventional configuration, when the temperature rises in fine weather because a certain amount of irrigation is performed regardless of weather such as sunny days, cloudy weather, and rain. Relative humidity decreases, so the water required for photosynthesis becomes insufficient, and if the water continues to deficient, it will die.
Also, if you irrigate on a rainy day, the water content will become excessive and it will cause decay, so depending on the weather of the day,
Furthermore, the set of timers had to be changed according to the changing weather, the time for the operator to monitor the irrigation system did not change much, and labor saving was small. Therefore, there has been a demand for a device capable of fine control.

[0004]

In order to solve such a problem, the present invention connects a sensor for detecting the amount of solar radiation and a means for operating an irrigation device to a controller, and the controller causes the sensor to operate. The values of are integrated and calculated,
It is configured to activate the irrigation system when the accumulated solar radiation exceeds a set value. Further, in the irrigation control device, the range of the irrigation permission time is set in the controller, and irrigation is possible only within the range. The integrated solar radiation amount is configured to be cleared every day.

[0005]

The irrigation device is activated when the solar radiation amount of the day is integrated by the controller 6 by the signal from the sensor 9 and the accumulated solar radiation amount reaches the preset value set in the controller 6 within the irrigation permission time. Then, irrigation is performed from the nozzle 5, and the irrigation work is repeated until the irrigation permission time ends. Then, at 12:00 pm, the integrated solar radiation amount is cleared, the solar radiation amount is integrated with sunrise, and the above is repeated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved by the present invention and the means for solving the problems are as described above. Next, referring to the embodiments shown in the accompanying drawings, FIG. 1 shows the overall construction of the irrigation control apparatus of the present invention. Fig. 2 is a perspective view, Fig. 2 is a front view showing the watering device in the house, Fig. 3 is a diagram showing a relationship between time and the amount of solar radiation, and Fig. 4 is a control flowchart.

The overall structure will be described with reference to FIGS. 1 and 2.
The irrigation device is installed in the houses 1 and 2 and
Are different in shape and arrangement depending on the kind of crops to be raised, for example, house 1 has a rotary seeding machine inside so that a large number of seedling raising boxes can be stored, and house 2 has seedling raising boxes arranged on a table. Although not shown in the figure, many houses are installed so that they can be controlled by one controller. The water supply hose 4 is connected to the house 1 or 2 by connecting the electromagnetic valve 3 or 3'to a water supply or a pump.
-It is sent to the nozzles 5 and 5'through 4'to enable watering.

For example, in the case of the house 2, the stands 10 are arranged in two rows and the seedling boxes 11, 11, ... Are placed on the stand 10. Then, rails 12, 13 and 13 are erected on the center and both sides of the ceiling of the house 2,
3, a movable base 14 having a substantially triangular shape is placed, and the movable base 14 is configured to be capable of reciprocating in parallel with the base 10 during irrigation work. Support columns 14b, 14b are provided on the bottom side 14a of the movable base 14. Are provided vertically, and the support columns 14b and 14
Nozzles 5'and 5'are arranged at the lower end of b.

The electromagnetic valves 3 and 3 ′ are electromagnetic proportional valves, and the opening of the valve is adjusted in proportion to electric power so that a large amount of water can be supplied in inverse proportion to humidity. The irrigation amount may be adjusted by changing the opening / closing time, or a plurality of nozzles having different sizes may be provided and switched. The solenoids of the electromagnetic valves 3 and 3'are connected to a controller 6 which is a control device, and the controller 6 further includes a sensor 7 and 7'for detecting the humidity in the houses 1 and 2 and a sensor for detecting the amount of solar radiation. 9 · 9 'is connected. And, a clock and a timer are built in the controller 6,
It comprises a keyboard 6b for inputting setting values and the like, and a monitor 6a for displaying the keyboard 6b. However, in FIG.
In the above, a single controller controls irrigation of a large number of houses. However, as shown in FIG. 5, it is possible to arrange controllers in each house and control them independently.

In such a structure, the keyboard 6b
Allows input of set values of irrigation permission start time b, irrigation permission end time d, and comparative cumulative solar radiation amount (irrigation operation cumulative solar radiation amount) f. The irrigation permission start time b and irrigation permission end time d are As shown in FIG. 3, when the sunrise time is a and the sunset time is e, it can be set between a and e. As an appropriate time, it is necessary to irrigate the sunrise and the sun. Water is used for effective photosynthesis only during the sunken period, and it is allowed a few hours after the sunrise when the temperature rises, and the accumulated amount of solar radiation reaches the specified amount within a few hours. It is better not to set it to a delayed time because it does not. If the permission end time is also set before sunset, water drops will remain in the evening and excess water content can be suppressed.

It is desirable that the comparative cumulative solar radiation amount f is set immediately before the amount of light increases and the water becomes insufficient. When the comparative cumulative solar radiation amount f is reached, irrigation is started and when the permission end time d passes. , Since water drops remain in the evening, irrigation cannot be performed even if the cumulative solar radiation amount reaches the comparative cumulative solar radiation amount f,
The accumulated amount of solar radiation is cleared on that day and is not carried over to the next day, so that if the next day is rain, water will not be needed but water will not be irrigated. The time for clearing this accumulated solar radiation amount may be 12 o'clock at night, but it is not particularly limited as long as it is between sunset e and sunrise a on the next day, and the solar radiation amount is carried over to the next day. It is good if you can avoid it.

Next, the irrigation control, which is the main part of the present invention, will be described in detail with reference to the flow chart shown in FIG. 4. First, whether or not the automatic control of the irrigation device is permitted from the keyboard 6b, and the irrigation permission start time b , The irrigation permission end time d and the set values of the irrigation operation accumulated solar radiation amount f are input (A), the solar radiation amount measured by the sensor 9 is input and integrated (B), and the current time is input (C). . It is judged whether the day has changed (D), and if it has changed, the integrated solar radiation amount g is cleared and (E) integration is started from 0. If the day has not changed, the set value is set as above. It is determined whether to change (F). When changing, that is, when the seedling condition, temperature, etc. must be taken into consideration during seedling raising, the set value is input (G) and written in the controller 6 (H).

If the set value is not changed, it is judged whether or not the irrigation system is automatically controlled (I). If the irrigation system is not automatically controlled, the electromagnetic valves 5 and 5'are manually operated for irrigation. In the case of automatic control, it is judged whether the irrigation time is within the permission time (J), and if it is within the permission time, it is determined whether n = 1 and the accumulated solar radiation amount g reaches the irrigation operation accumulated solar radiation amount f ( K), when the irrigation possible solar radiation amount f is exceeded, n = n + 1 is set so that the next irrigation operation cumulative solar radiation amount becomes 2f, and then the value from the humidity sensor 7 is input (M), which is inversely proportional to the value. The above procedure is repeated by performing (N) the irrigation of the specified amount. That is, when the humidity is high, the irrigation amount is small, and when the humidity is low, the irrigation amount is large. However, the proportional constant with respect to the humidity may be set arbitrarily or may be input from a conversion table or the like.

[0014]

Since the present invention is configured as described above, it has the following effects. That is, irrigation is performed according to the accumulated solar radiation amount, so that it becomes possible to give optimum water to the seedlings, and since the irrigation permission time can be set, water drops on the leaf surface at sunset. Remaining, less likely to become sick and ill, and because the cumulative solar radiation is canceled on that day, it will not be irrigated when the humidity is high and irrigation is unnecessary when the rain continues.
It no longer hurt the growth of seedlings.
