Description

Apparatus For Alerting Time For Sprinkle Water Of Plant}

The present invention relates to a device for notifying time of watering of plants, and more particularly, after setting the moisture range of the soil suitable for plants planted in the soil, the moisture of the soil is measured to measure the moisture range of the soil and the moisture. The present invention relates to a plant watering timing notification device that can increase the efficiency of plant cultivation by informing a user whether a plant's watering time is reached by comparing measured values.

In plant horticulture, artificial irrigation is necessary because crops are grown in a state where rainfall is blocked. In addition, crops may have different growth responses depending on the moisture conditions in the soil. For example, if the water is misused, the crops may be stressed by over-wetting or drying. In particular, the proper moisture demand varies greatly depending on the type of plant, but growers who are ignorant of the growing environment of such various plants often kill the plants because they do not create the proper environment.

Despite such importance, conventional watering methods tend to depend mostly on the experience of the operator. In other words, it is common to determine the time and frequency of watering, etc., by the subjective judgment of the worker. Therefore, it is difficult to maintain proper soil moisture according to the crops. Such inadequate watering affects the crops and reduces the efficiency of plant cultivation. It has been an important cause.

In addition, in some cases, about 30% of the labor force is invested in plant cultivation for the purpose of managing irrigation, which leads to enormous cost and time. In order to avoid such a subjective watering method and to precisely manage the watering of the soil, a technology capable of precisely measuring the moisture in the soil and informing the user of the proper watering time according to the proper moisture environment of each plant is required.

However, the prior art focuses only on the accurate measurement of the moisture content in the soil, overlooking the fact that the amount of water required by plants differs, and merely measuring and displaying the moisture content of the soil so that the user can accurately measure the water content of the plant. There was a problem that it was difficult to determine the timing.

The present invention has been made in order to solve the above problems, and after setting the required soil moisture range according to the type of plants planted in the soil to measure the moisture of the soil to set the moisture setting range and the moisture measurement value It is an object of the present invention to provide a plant watering timing notification device that tells the user whether or not to reach the watering timing of the plants by comparing.

Watering appropriate time notification device of the present invention for achieving the above object,

Moisture sensing unit for measuring the moisture content of the soil in which the plant is planted;

A moisture setting unit for setting an appropriate moisture range of the soil required according to the type of the target plant;

A control unit connected to the water detecting unit and the water setting unit to determine whether the watering time is reached by comparing the water measurement value of the water detecting unit with the water setting range of the water setting unit;

And a display unit connected to the control unit to display whether the watering time is reached to the user.

According to the watering period timing device of the present invention as described above,

First, you can set the required soil moisture value according to the type of plant planted in the soil.

Second, by comparing the moisture set value and the moisture measurement value of the soil, the user can easily determine whether the water is at the time when the water is suitable for watering can effectively reduce the cost and time spent on the watering of the plant.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting of the present invention. A singular expression includes a plural expression unless the context clearly indicates otherwise. In this application, the terms “comprises” or “having” are intended to indicate that there is a feature, number, step, action, component, part, or combination thereof described in the specification, and one or more other It is to be understood that the present invention does not exclude the possibility of the presence or the addition of features, numbers, steps, operations, components, parts, or a combination thereof.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the soil moisture measuring apparatus according to the present invention includes four parts of the moisture detecting unit 100, the moisture setting unit 200, the control unit 300, and the display unit 400.

First, the moisture detection unit 100 measures the content of moisture contained in the soil. At this time, the method of measuring the moisture content includes all the moisture measuring methods available to those skilled in the art, the present invention uses a TDR (Time Domain Reflectometry) method as an embodiment.

The TDR method generates a high frequency from a TDR trace, passes a high frequency wave through a sensor bar consisting of a pair of balanced bar wires, and then returns from the end of the bar. How to measure. Since the propagation speed varies according to the soil moisture content around the sensor rod, the moisture content of the soil can be accurately measured using the above method.

In addition to the TDR method described above, by using the principle that the electrical resistance of the soil is changed according to the water content, the electrical resistance ingots of a pair of electrodes are buried in the soil, and the resistance is measured when the resistance and soil equilibrium are achieved. The electrical resistance method, or the Psychrometry method for measuring the soil moisture state, that is, the potential by measuring the vapor pressure inherent in the soil pores, can be used.

In addition, the sensor unit may be configured to include a plurality of moisture measurement sensors (110, 120, 130). That is, as shown in FIG. 2, the moisture content of the soil can be measured more accurately by distributing a plurality of moisture measuring sensors evenly in the soil.

On the other hand, in the moisture setting unit 200, the content of water requiring watering is adjusted by the user. In general, the amount of water in the soil that requires watering is different for each plant. For example, a species that does not require any moisture, such as a cactus, should be set to a fairly small moisture range, while a species that needs to supply a certain amount of moisture at all times should be set to a very high moisture range.

Therefore, the present invention proposes a moisture setting unit 200 that allows the user to adjust the appropriate moisture range according to the type of plant. The moisture setting unit 200 may be manufactured in a digital manner or an analog manner. In the present invention, two examples of the analog manner will be described.

In the case of the device shown in Figure 3, there are five buttons from A to E. The user can adjust the moisture setting range by pressing each button. Pressing the A button sets the lowest moisture range, which can be used for plants such as cacti. Conversely, pressing the E button sets the highest moisture range and can be used for plants that need a lot of moisture. In this way, you can adjust the appropriate moisture range according to the type of plant.

4 illustrates an embodiment of an apparatus capable of adjusting the appropriate moisture range by moving one button from the A to the E position, rather than adjusting the proper moisture range with a plurality of buttons.

The moisture measurement value measured by the moisture detection unit 100 is compared with the appropriate moisture range set by the moisture setting unit 200 in the control unit 300. If the moisture measurement value is smaller than the appropriate moisture range, the control unit 300 transmits a signal indicating that the watering time has arrived to the display unit 400. In addition, the controller 300 serves to supply power to the moisture detecting unit 100, the moisture setting unit 200, and the display unit 400.

The display unit 400 receiving the watering time arrival signal from the controller 300 notifies the user that the watering time has arrived. In this case, all the methods for notifying the user of the watering time may be used as a method of notifying. For example, the display unit may emit sound or light at a predetermined time interval, or the display unit may rotate.

When the display unit rotates, rotation is possible by a device such as a driving motor, and a power supply device for this purpose is additionally configured.

While the invention has been shown and described with respect to certain preferred embodiments, the invention is not limited to these embodiments, and those of ordinary skill in the art claim the invention as claimed in the appended claims. It includes all the various forms of embodiments that can be implemented without departing from the spirit.
