Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic watering system which is used in a golf course, a fruit garden or the like where a relatively large area is occupied and which automatically sprays water from a watering device at a preset time.

[0002]

2. Description of the Related Art A conventional automatic watering system installed at a golf course, a vegetable garden, etc.
It is designed to automatically sprinkle a certain amount of water. In other words, the water is sprinkled without considering whether it is raining or not.

However, after raining, sprinkling may not be necessary depending on the amount of rainfall. In addition, there is also a problem that water is oversprayed by sprinkling water after it rains, which promotes excessive growth of grass and the like, or hinders healthy growth on the contrary.

Therefore, in order to prevent such a situation and perform good watering, an automatic watering system for controlling the watering amount according to the rainfall amount (for example, Japanese Patent Laid-Open No. 5-336851).
(See Japanese Patent Publication).

In this automatic watering system, for example, when there is a rainfall amount of 15 mm 5 hours before the watering time and 5 mm 5 hours before the watering time, the rainfall amount data before the watering is stored in the second memory. From the database showing the relationship with the water amount data, "5 hours ago ... 5 mm" and "4 hours ago ...
Find the amount of water sprinkled at 15 mm. Then, the smaller sprinkling amount (5 mm in this case) of the obtained sprinkling amounts is selected, and the sprinkling of the selected 5 mm is automatically performed at the sprinkling time.

As described above, in the conventional automatic watering system, the amount of rainfall for a certain period of time before the watering time is detected, and the amount of watering is controlled based on the detection result.

[0007]

However, in the above-mentioned conventional automatic watering system, the amount of rainfall is taken into consideration, but other conditions are not taken into consideration. In other words, conditions such as whether it is sunny or cloudy after raining are not added, and at the time of watering, the amount of water sprayed will be determined based on only the amount of rainfall so far. ing.

Further, when it does not rain, 20 mm of water is uniformly sprayed, and the fact is that the sunshine duration, season and degree of dryness are not taken into consideration at all. In other words, the conventional automatic watering system has a problem that it cannot be said that the watering control is in actual conditions.

The present invention was devised to solve such problems, and its purpose is to make it possible to control watering in a more practical manner by considering not only the amount of rainfall but also the amount of sunshine. To provide an automatic watering system.

The structure extends to the bottom of 1c.

Although the rainfall amount measuring unit 21 and the sunshine amount measuring unit 22 shown in FIG. 4 are configured to transmit each measurement data to the host computer 7 side via the underground burying line, It can be configured to transmit to the host computer 7 by a wireless line instead of a line. In this case, the watering amount calculating unit 23 (see FIG. 4) installed in the management building 31 is installed in the vicinity of the rainfall measuring unit 21 and the sunshine amount measuring unit 22, and the watering amount calculating unit 23 is wirelessly connected. A transmitter (not shown) is attached, and measurement data is transmitted from this wireless transmitter to the host computer 7 side.

FIG. 7 shows another embodiment of the sunshine amount measuring section 22.

The solar radiation amount measuring unit 22 is provided with a solar cell (not shown) on the back surface of a light receiving plate (glass plate or plastic plate) 22a which is inclined to receive sunlight almost vertically.

It is like this.

In addition to this, although not shown, an illuminance meter may be used as the sunshine amount measuring unit 22 to measure the sunshine amount by detecting the intensity of sunlight.

FIG. 1 is a block diagram showing the electrical construction of the automatic watering system of the present invention.

In the figure, the output of the rainfall amount measuring unit 21 for outputting the rainfall amount data and the output of the sunshine amount measuring unit 22 for outputting the sunshine amount data are led to the watering amount calculating unit 23. In addition, the watering amount calculation unit 23 stores a first weather coefficient A created based on a preset rainfall amount and a second weather coefficient B created based on a preset sunshine amount. A storage unit 24 that holds a data table indicating the relationship is bidirectionally connected. The output of the sprinkling amount calculation unit 23 is guided to the sprinkling control unit 25.

In this embodiment, the watering control section 25 is substantially constituted by software executed by the host computer 7.

The storage unit 24 stores the relationship between the first weather coefficient A created based on the preset rainfall amount and the second weather coefficient B created based on the preset sunshine amount. It is a block that holds the data table shown.

FIG. 8 is a table (referred to as Table 1) showing an example of the data table stored in the storage unit 24.

In this data table, the first weather coefficient A divides the amount of rainfall per day into 6 horizontal columns at intervals of 5 mm,
Coefficients 10, 8, 6, 4, 2, in order of decreasing rainfall
0 is assigned to each. Also, the second weather coefficient B
Is divided into 6 vertical columns, and the coefficient is 1 in descending order of day illuminance.
0, 8, 6, 4, 2, 0 are assigned respectively. Regarding the second weather coefficient B, for example, the column to which the coefficient 10 is assigned (uppermost column) shows the day illuminance at the time of fine weather in midsummer, and the column to which the coefficient 0 is assigned (lowermost column) is at all. It shows the illuminance when the sun does not illuminate.

Each block in which the vertical and horizontal columns intersect is a block showing a specific numerical value (%) of the actual weather coefficient C, and an appropriate numerical value is assigned corresponding to each coefficient. . However, the block in which the numerical values are enclosed in parentheses is a numerical value that is actually impossible, and this part can be said to be a block that does not need to be set originally. That is, these blocks show that it rained as much as 16 to 25 mm on that day despite the daily illuminance being 10, which is practically impossible. Therefore, even if a numerical value is contained in these blocks, it does not occur when actually selected, so that it does not affect the actual control.

FIG. 9 is a table (referred to as Table 2) showing another example of the data table stored in the storage unit 24.

In this data table, the first weather coefficient A divides the amount of rainfall per day into 5 horizontal columns in 5 mm intervals,
Coefficients 100, 75, 50, 2 in order of decreasing rainfall
5 and 0 are assigned respectively. In addition, the second weather coefficient B is divided into four vertical columns of fine, cloudy, cloudy / rainy, and rain, and the coefficients 100, 60, 30, and 0 are assigned in order from the fine column having the highest illuminance.

Each block where the vertical column and the horizontal column intersect is a block showing the actual weather coefficient C, and the numerical value obtained by multiplying the coefficient of each column is entered.

The sprinkling amount calculation unit 23 uses the first weather coefficient stored in the storage unit 24 based on the rainfall amount data obtained by the rainfall amount measuring unit 21 and the sunshine amount data obtained by the sunshine amount measuring unit 22. The actual weather coefficient C is obtained from a data table (for example, Table 1 or Table 2) showing the relationship between A and the second weather coefficient B, and the actual weather coefficient C and a preset reference watering amount D are set.
It is a calculation block for obtaining the actual water amount E based on

That is, the actual weather coefficient C is shown in Table 1 or Table 2.
It is obtained by reading the numerical value shown in each block of. Further, the actual water spray amount E is obtained by integrating the actual weather coefficient C and the reference water spray amount D.

Here, the reference watering amount D is, for example, the maximum watering amount (or the maximum watering time) during fine weather in midsummer. However, the maximum amount of water sprayed depends on the type of plant, latitude, surrounding topography, northward or southward, geology (sand, clay, field, etc.), installation density of sprinkler 4, caliber and injection pressure, etc. Since it greatly differs depending on the condition, it is appropriately determined in consideration of such conditions. For example, the maximum watering amount is determined to be 20 mm (maximum watering time is 40 minutes, etc.), and the maximum watering amount is 30 mm (maximum watering time is 1 hour, etc.).

Further, in addition to the standard watering amount D (that is, the maximum watering amount) determined in this way, a coefficient depending on the kind of plants in the vicinity to be watered, a coefficient depending on the season, a temperature coefficient,
One or a plurality of types of reference water spray amounts D (for example, D ′, D ″ ...) May be set in consideration of the humidity coefficient and the atmospheric pressure coefficient.

In this way, the reference water amount D (for example, D ',
When D ″ ...) is set finely, it becomes a particularly effective system when growing plants sensitive to the watering amount.

For example, the temperature coefficient is 0.5 up to 9 ° C., 0.6 at 10 to 14 ° C. and 0.1 at 15 to 19 ° C.
7, 20 to 24 ° C is 0.8, 25 to 29 ° C is 0.9, 3
When 0 ° C or higher is set to 1, and as a seasonal coefficient, as shown in an example in FIG. 10, March is 0.8, April to October is 1.0, November is 0.8 and December. From January to February is 0.5.

Although the specific examples of the humidity coefficient and the atmospheric pressure coefficient are omitted, they can be set in the same manner as the temperature coefficient and the like. For example, the humidity coefficient is higher in the range of 0 to 1 as the humidity is lower (that is, closer to 1), and the atmospheric pressure coefficient is higher in the range of 0 to 1 that is higher (that is, closer to 1). ) Set each.

Then, by appropriately combining the coefficients set in this way and multiplying it by the maximum watering amount, the reference watering amount D for only that combination is set.
Then, from the set values, the standard watering amount D to be used as needed is selected, and is set as the reference watering amount D for obtaining the actual watering amount E.

The sprinkling control unit 25 is a control block that sprinkles water from the sprinkler 4 by the actual sprinkling amount E calculated by the sprinkling amount calculation unit 23 at a preset time. For example, when the actual water spray amount E is 20 mm, the control valve 12 is turned on for 40 minutes to control the sprinkler 4 to spray water.

However, at the time of sprinkling control, the actual sprinkling amount E
The simplest method is to convert the time into a time and count the time with a timer or the like, but a water meter is attached to the water supply pipe 6 or the branch pipe 8a, and the actual water spray amount E is directly measured by this water meter. However, it may be configured to control watering.

Next, a concrete example of the operation of the automatic watering system having the above configuration will be briefly described.

The storage unit 24 stores the database shown in Table 1. Further, the standard water amount D is
It is calculated by multiplying the maximum sprinkling amount by a coefficient depending on the type of plant in the vicinity to be sprinkled, a coefficient depending on the season, a temperature coefficient, a humidity coefficient, a pressure coefficient, etc., and in this embodiment, 20 mm / day (40 minutes). And

The system is operated under the above setting conditions, and the rainfall amount and sunshine amount are measured by the rainfall amount measuring unit 21 and the sunshine amount measuring unit 22. That is, the rainfall amount measuring unit 21 measures, for example, the amount of rainfall for one day, and outputs the measured rainfall amount data to the watering amount calculating unit 23. Also,
The sunshine amount measuring unit 22 also measures the sunshine amount for one day,
The measured sunshine amount data is output to the watering amount calculation unit 23. In the sprinkling amount calculation unit 23, based on the rainfall amount data obtained from the rainfall amount measuring unit 21 and the sunshine amount data obtained from the sunshine amount measuring unit 22, Table 1 stored in the storage unit 24
First, the actual weather coefficient C is obtained from the data table of.

Assuming that the rainfall data is 10 mm (coefficient 8) and the sunshine amount is coefficient 6, the actual weather coefficient C is 40 (%) from the data table of Table 1.

The watering amount calculating section 23 integrates the actual weather coefficient C (= 40%) obtained from this data table and the preset reference watering amount D = 20 mm / day (40 minutes),
Obtain the actual water amount E = 20 mm × 0.4 = 8 mm (16 minutes).

The data indicating the actual water spray amount E = 8 mm (16 minutes) is given to the host computer 7, which is the water spray controller 25. The host computer 7 controls to sprinkle the sprinkler 4 by the actual sprinkling amount E at a preset time based on the data of the sprinkling amount E. That is, the control valve 12 is turned on for 16 minutes while measuring with a timer or the like, and the sprinkler 4 is controlled to sprinkle water.

It should be noted that in the above embodiment, the table 1 is stored in the storage unit 24.
Although the case where the database shown in is stored is described, the calculation of the actual water spray amount E when the database shown in Table 2 is stored in the storage unit 24 is as follows.

That is, the rainfall data is 10 mm (coefficient 7
5), assuming that the amount of sunlight is cloudy (coefficient 60), Table 2
From the data table of, the actual weather coefficient C is 4500.

Here, the standard water amount D selected when the data table of Table 2 is used is 20 mm / day (40 minutes).
Will be set as a value corresponding to the maximum value of the actual weather coefficient C (10000 written in the upper left block). Therefore, the sprinkling amount calculation unit 23 calculates the actual sprinkling amount by the following formula from the actual weather coefficient C (4500) obtained from this data table and the preset standard sprinkling amount D = 20 mm / day (40 minutes). Ask for E.

[0087]

[Equation 1] E = D × 4500/10000 = 20 × 0.4
5 = 9 mm (18 minutes) Further, in the above embodiment, the second weather coefficient B is configured to be obtained based on the amount of sunshine measured by the sunshine amount measuring unit 22, but the second weather can be visually determined. The coefficient B may be obtained. In this case, the degree of dryness of soil and sand should be examined by taking into account empirical information such as weather conditions, sunshine duration within the past 2-3 days, and sprinkling conditions. Check the dryness of the soil or sand by visual inspection or the feel when picked up. That is, soil and sand (eg Kanuma soil, Hyuga stone, Akadama soil, clay ball, etc.)
The color becomes lighter as it dries, and the degree of drying can be judged by examining this color. Also, check the luster and wilting condition of plants such as grass. Also, dry /
As a sample, plants that appear sensitive to appearance due to humidity
It can also be judged from the luster and wilting condition of this plant.

Here, an example in which the second weather coefficient B is visually determined is shown in FIG.

In the figure, the rainfall amount measuring unit 21 is the same as that shown in FIG. 5, has a water level detector 21d, and the sunshine amount measuring unit 22 is based on visual observation or the like without depending on the equipment. In addition, the amount of water spray calculation unit (first weather coefficient A calculation unit)
The unit 23 is installed in the vicinity of the rainfall amount measuring unit 21 together with the wireless transmitter 41. Then, the amount of water sprinkling calculation unit 2
The data based on, for example, the amount of rainfall per day calculated by 3 is transmitted from the wireless transmitter 41 and received by the host computer 7 via the transmission / reception antenna 42 on the host computer 7 side. That is, the transmission / reception antenna 42 is an antenna that receives data based on the amount of rainfall from the wireless transmitter 41 and transmits a control signal from the host computer 7 to the control valve 12 side.

Second weather coefficient B visually determined
Is directly input to the host computer 7. As an input method, there are a method of operating the touch panel on the display screen for inputting, a method of operating the keyboard for inputting, and the like.

In the host computer 7, the data (data corresponding to the first weather coefficient A) based on the amount of rainfall obtained from the water spray amount calculation unit 23 and the second weather by visual observation or the like input from the touch panel or keyboard. Based on the coefficient B, the actual weather coefficient C is obtained from a data table (for example, Table 1 or Table 2) showing the relationship between the first weather coefficient A and the second weather coefficient B. Then, the actual water spray amount E is obtained based on the actual weather coefficient C and the preset standard water spray amount D, and based on the data of the actual water spray amount E, at the preset time, only the actual water spray amount E is obtained. The sprinkler 4 controls to sprinkle water.

In the above embodiment, the rainfall measuring unit 21
The unit for collecting data by the sunshine amount measuring unit 22 (or visual observation) is set to be every day, but it may be set to be every hour or every week.
