Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic control method for a water sprinkler.

The purpose of watering equipment is to add moisture to the soil in order to maintain the condition of ball game fields, grow crops, etc.

An example of a conventional sprinkler device is shown in FIG.

In the figure, (1) is a tennis court, f21 is a fence,
(3) is the water supply pipe, (4) is the water tank, (5) is the water supply pump, (6) is the water supply manual valve, and (7) is the water supply pipe for the sprinkler.

(8) is the water sprinkler, (9) is the pump operation control panel, and un is the pump wiring.The operation of the 0th order will be explained.

When water enters the water tank (4) from the water supply pipe (3), turn on the pump start switch on the pump operation panel (9).
By increasing the pressure with the water supply pump (5) and opening the water supply manual valve (6), water is sprinkled from the right-angle discharge type water sprinkler (8) installed at the corner of the tennis court via the water supply pipe (7) for the sprinkler. Water will be sprinkled throughout the tennis courts and two tennis courts using four water sprinklers. When stopping watering, check the humidity of the tennis court (1), close the water supply manual valve (6), and stop the water supply pump (5).

In addition to the manual method described above, there is also a method in which watering time is controlled using a timer. This method uses a busy water supply solenoid valve instead of the manual water supply valve (6), and a timer is installed in the pump operation control panel (9).
) and the water supply solenoid valve to start and stop watering.

After watering is completed, tennis courts are often compacted and maintained with rollers while the soil is still moderately moist to maintain a good ground condition.

Since it is configured as explained above, the two-manual method requires human operation and judgment of the soil moisture condition.
If the moisture level of the soil is 7+, it tends to be insufficient.

A method controlled by a timer allows for automatic watering, but watering is performed within the timer setting regardless of the moisture level of the soil on the tennis court. For this reason, even when watering is not necessary, such as when it rains or after rain, or when a small amount of sprinkler is sufficient, water and pump power are wasted unless the sprinkler is manually stopped. In addition, since water is always sprinkled for a certain period of time regardless of the moisture level of the soil on the tennis court, there is a drawback that the moisture level tends to be too high or too low.

In recent years, the spread of various sports facilities has been remarkable, and in addition to all-weather ball game grounds, there are also many soil or grass ball game grounds, and various watering devices are being used.

On the other hand, various watering devices have been conventionally used in agricultural facilities to grow vegetables and fruits.

The present invention has been made in view of these points, and provides a method for sensing the humidity in the soil and automatically controlling the amount of watering in accordance with the humidity in the soil.

An embodiment of the present invention will be described below with reference to the drawings.

In Figure 2, (11 is the tennis court, (2) is the fence, (3) is the water supply pipe, (4) is the water storage IVy t (5
) is the water supply pump, (7) is the water supply pipe for the sprinkler, (8)
is the sprinkler, Ql is the wiring for the pump, Ql) is the water supply solenoid valve, 0~ is the humidity sensor, (11 is the automatic watering control panel with a humidity controller inside the panel, t('i, water start timer, water supply) 60→, which contains the control circuit for the pump (5) and the water supply solenoid valve (111), is wiring for a humidity sensor, and 09 is wiring for a water supply solenoid valve.

Next, the operation will be explained. (Tennis coat) (11 is for rolling and maintenance using equal pressure rollers before use.

It is necessary to keep the soil moderately moist. For this reason, the watering start timer built in the automatic watering control panel 0 sends a signal from the humidity sensor O) to the humidity controller built in the automatic watering control panel 03 via the humidity sensor wiring I when the starting time comes. When the humidity level of the humidity sensor is low, the water supply solenoid valve wiring (through the country, the water supply solenoid valve Uυ is energized,
The water supply solenoid valve (Ill opens, and at the same time, the water supply pump motor is energized via the pump wiring 0I, and the water supply pump (
5) is operated. When the water supply pump (5) is operated and the water supply solenoid valve Ql) is opened, water passes from the water storage tank (4) through the water supply pipe (3), the pressure is increased by the water supply pump (5), and the water supply pipe for the water sprinkler ( 7) and from the water sprinkler (8) to the tennis court).
When the signal from the humidity controller exceeds a preset humidity level, the water supply electromagnetic valve (α) and the water supply pump (5) are stopped by a command from the humidity controller. Even at the watering start time, if the signal from the humidity sensor α2 indicates that watering is unnecessary, that is, the humidity level is higher than a preset level, the water supply electromagnetic valve (11) and the water supply pump (5) do not operate.

Therefore, the humidity sensor (l'IJ) can be used to automatically control the pressure of the sprinkler system.

Next, in Fig. 3, a4 is a humidity sensor, and H is a humidity sensing element.

01 is the terminal connection box, (II is the humidity sensor mounting plate and lid for inspecting the humidity sensor, (II is the electric heater for atmosphere recovery, (2) is the net for moisture sensitive prevention acquisition, QO is the electric heater for atmosphere recovery storage case.

Q is the underground box for storing the humidity sensor, (2) is the upper ventilation hole, ci
A is the side ventilation hole, (c) is the drain hole, (a) is the wiring for the electric heater for atmosphere recovery, and @ is underground.

Next, the operation of the humidity sensor 02 will be explained. Moisture sensing element 0Q
has the property of changing its electrical resistance according to changes in the humidity of the atmosphere, and the terminal junction box Q? ) is fixed/connected to. The electrical resistance value is measured via the sensor wiring (+4).

This information is sent to the humidity controller built into the automatic watering control panel. In order to maintain the accuracy of the humidity sensing element θe, the electric heater a1 for atmosphere recovery uses electricity that is sent from the humidity controller built in the automatic watering control panel (11) through the wiring for the electric heater for atmosphere recovery (c). Activated by.

The atmosphere of the humidity sensing element Q0 in the humidity sensing device storage underground box (2) is maintained in a normal state. The atmosphere in the ground (5) is maintained through the upper ventilation hole (C) and side ventilation hole (F) provided in the underground box housing the humidity sensor, preventing the moisture sensing element On from coming into direct contact with soil, etc. Therefore, it is transmitted to the humidity sensor αQ through the moisture sensor prevention erection net (A), which is attached. Therefore, it can sense the humidity in the soil.

As described above, the automatic control method for a sprinkler device according to the present invention eliminates the conventional manual method of human operation and judgment of the humidity state of the ground, etc.
111. Excess/deficiency of moisture condition with fill-Ill method using timer, water and pump. This has the effect of eliminating unnecessary use of force.

What is shown in FIGS. 2 and 3 is just one embodiment of the present invention, and the application is not limited to tennis courts, but also for watering other ball game grounds, agricultural crops, (O(
It goes without saying that various modifications may be made to watering trees, lawns, etc. without departing from the gist of the present invention.

For example, the placement of the humidity sensor fil, the number 2 water sprinkler (8) and the humidity sensor 06! Regarding the positional relationship, etc., it is only necessary to use the optimal method according to each case.
