The electronic device 100 that generates sound waves for growing crops of the present invention acquires the first height difference between the crops and the sound wave generation module 110 through the detection sensor 130 (S310), and obtains the first height difference and By controlling the lifting device 120 based on the reference height difference, the height of the sound wave generation module 110 is automatically adjusted (S320), and sound waves having a preset frequency and intensity are output through the sound wave generation module 110. (S330).

Specifically, as the height of the electronic device 100 increases from the ground of the crops due to the growth of the crops, the first height difference, which is the height difference between the crops and the sound wave generation module 110, decreases.

Accordingly, the electronic device 100 uses an elevating device 120 to prevent a situation in which the sound waves output from the sound wave generation module 110 are blocked by crops close to the electronic device 100 and cannot be transmitted to other crops. Through this, the height of the sound wave generation module 110 can be increased to be spaced apart from the crops by the standard height difference.

At this time, the reference height difference is a height difference preset to be maintained between the sound wave generation module 110 and the crops.

In an embodiment, when performing step S320, as preset, if the first height difference exceeds the reference height difference, the electronic device 100 controls the height of the sound wave generation module 110 through the lifting device 120. Thus, the height difference between the sound wave generating module 110 and the crops can be controlled to be equal to the reference height difference.

Alternatively, as preset, the electronic device 100 generates sound waves through the lifting device 120 when the first height difference exceeds the reference height difference and the difference value between the first height difference and the reference height difference exceeds a certain value. By controlling the height of the module 110, the height difference between the sound wave generating module 110 and crops can be controlled to be equal to the reference height difference.

Alternatively, as preset, the electronic device 100 raises the sound wave generation module 110 when the first height difference exceeds the reference height difference and the difference value between the first height difference and the reference height difference exceeds a certain value. Considering the change in height according to the growth speed of the crop that occurred immediately before, the height of the sound wave generation module 110 is controlled through the lifting device 120, so that the height difference between the sound wave generation module 110 and the crop is the first height. By controlling the difference value between the car and the reference height difference to be equal to the sum of the reference height difference, the number of times the lifting device 120 is driven can be reduced.

At this time, the intensity (dB, decibel) of the sound wave generated from the sound wave generation module 110 increases in proportion to the ratio of the difference between the first height difference and the reference height difference, which is added to the reference height difference, to the reference height difference, and is output. It can be.

Here, the intensity of the sound wave before being increased and output is a preset reference intensity, and then, when the remeasured first height difference is equal to the reference height difference, the intensity of the sound wave will be corrected to the reference intensity by the electronic device 100. You can.

In addition, the electronic device 100 stores power generated through the solar panel 160 in the power device 150, and when a user input to the lifting device 120 is obtained through the switch 170, the user The lifting device 120 can be controlled based on the input.

At this time, the electronic device 100 may obtain the second height difference between the crop and the sound wave generation module 110, which is changed according to the user input, through the detection sensor 130, and store the second height difference as the reference height difference. there is.

Accordingly, when the second height difference exceeds the threshold, the electronic device 100 calculates a first weight proportional to the difference value between the second height difference and the threshold, and calculates the intensity of the sound wave output from the sound wave generation module 110. is increased by applying the first weight to .

On the other hand, when the second height difference is below the threshold, the electronic device 100 calculates a second weight proportional to the difference value between the second height difference and the threshold, and adds a second weight to the intensity of the sound wave output from the sound wave generation module 110. It can be reduced by applying weight.

At this time, the threshold may be the initially set reference height difference before change.

Specifically, when the second height difference according to the user's command input through the switch 170 exceeds the standard height difference before the change, the height difference between the sound wave generation module 110 and the crops increases, so the electronic device 100 ) prevents the crop production effect due to sound waves from decreasing by increasing the intensity of the sound wave in proportion, but when the second height difference is less than the standard height difference before the change, the height difference between the sound wave generation module 110 and the crops decreases. Therefore, by reducing the intensity of the sound wave in proportion, unnecessary waste of power due to the intensity of the sound wave output from the sound wave generation module 110 can be prevented.

Meanwhile, the electronic device 100 of the present invention can provide images acquired in real time through the camera 190 to the user terminal through the communication unit 180.

At this time, the detection sensor 130 is fixed to the sound wave generation module 110 and the upper/lower joint flaquette 122, and is moved to the same height when the sound wave generation module 110 is moved up/down by the lifting device 120. It is moved.

It can be.

6 to 8 are implementation examples according to an embodiment of the present disclosure.

In the electronic device 100 of the present invention, the electronic device 100 can identify the distance between the sound wave generation module 110 and the detection sensor 130 as the reference height difference between the sound wave generation module 110 and the crops, Accordingly, as shown, as the crop is recognized by the detection sensor 130, it is determined that the first height difference has reached the reference height difference, and through the lifting device 120, the detection sensor The sound wave generation module 110 can be raised to a point where crops are not detected at (130).

Accordingly, as the crops grow from the first to the third time points, the electronic device 100 controls the sound wave generation module 110 to rise by a height proportional to the change in height of the crops, so that the sound wave generation module 110 outputs It is possible to prevent sound waves from being blocked and reflected by crops and not being transmitted to other crops.

Meanwhile, when the height of the sound wave generating module is located at the critical height, but the difference value between the first height difference and the reference height difference is less than a certain value, the electronic device 100 generates a signal proportional to the difference value between the first height difference and the reference height difference. A third weight may be calculated and applied to the intensity of the sound wave output from the sound wave generation module to be inversely proportional to the difference between the first height difference and the reference height difference.

The critical height is the limit to which the sound wave generating module 110 can rise by the lifting device 120, and therefore, when the sound wave generating module 110 reaches the critical height, it is no longer possible to rise.

Accordingly, after the sound wave generation module 110 reaches the critical height, the electronic device 100 operates as the crops grow, and when the height difference between the sound wave generation module 110 and the crops decreases below the standard height, By reducing the intensity of the sound wave in proportion to the amount of change in the first height difference that is continuously acquired, unnecessary waste of power due to the intensity of the sound wave output from the sound wave generation module 110 can be prevented.

In addition, the electronic device 100 calculates the amount of change in height difference at a certain time interval through the detection sensor 130, calculates a fourth weight proportional to the amount of change in height difference, and the sound wave intensity inversely proportional to the amount of change in height difference. The time interval for adjustment can be calculated.

Accordingly, when the difference between the first height difference and the reference height difference is less than a certain value, the fourth weight is applied to the intensity of the sound wave output from the sound wave generation module at each time point according to the time interval for sound wave intensity adjustment. can be adjusted.

On the other hand, if the difference value between the first height difference and the reference height difference is greater than or equal to a certain value, the electronic device 100 may adjust the intensity of the sound wave output from the sound wave generation module to the intensity of the reference sound wave.

Specifically, the electronic device 100 may calculate the amount of change in height difference based on the first height difference acquired at regular time intervals as the crop grows, and accordingly, the height of the sound wave generation module 110 increases. In a constant state, but the distance between the crops and the sound wave generation module 110 is getting closer (the difference between the first height difference and the reference height difference is less than a certain value), a fourth weight proportional to the change in height difference is applied, As the distance between the sound wave generating modules 110 becomes closer, the intensity of the sound wave decreases.

At this time, the larger the rate of change in height difference, the faster the crops grow, and as sound wave intensity adjustment becomes more frequently necessary in proportion to the growth rate, the electronic device 100 calculates the time interval for sound wave intensity adjustment to be inversely proportional to the change rate of height difference. can do.

Afterwards, the growth of crops stops or the height of the sound wave generation module 110 increases, and the distance between the crops and the sound wave generation module 110 is maintained at the standard height difference (the difference between the first height difference and the reference height difference is a constant value). or more), the electronic device 100 adjusts the intensity of the sound wave output from the sound wave generation module 110 to the initial value, which is the intensity of the reference sound wave.

In an embodiment, when the growth of crops stops and the height difference between the crops and the sound wave generation module 110 is maintained for more than a certain time, the electronic device 100 emits sound waves of a pre-registered intensity at certain time intervals for preventing pests and diseases. The sound wave generation module 110 is controlled to be output according to .

At this time, the electronic device 100 may provide the user terminal 200 with the point in time when crop growth is complete through the communication unit 180.

As an example, when the growth of crops has stopped and the height difference between the crops and the sound wave generation module 110 is maintained beyond a certain time, if the sensing value obtained through the illuminance sensor 131 is within the critical range, the electronic The device 100 determines that the current time is the sunrise and sunset time zone, controls the lifting device 120 so that the sound wave generating module 110 is located at the critical height (top), and sets the first intensity at a first time interval. The sound wave generation module 110 is controlled so that sound waves are output.

In addition, when the sensing value obtained through the illuminance sensor 131 exceeds the threshold range, the electronic device 100 determines that the current time is daytime, and the sound wave generation module 110 rises and falls at a constant speed. The lifting device 120 is controlled to repeat, and at a second time interval that is longer than the first time interval, a sound wave of a second intensity (a intensity previously registered for pest prevention) that is lower than the first intensity is output. The sound wave generation module 110 can be controlled as much as possible.

In addition, if the sensing value obtained through the illuminance sensor 131 is less than the critical range, the electronic device 100 determines that the current time is night time and sets the sound wave generation module 110 to be located at the critical height (top).
