Here, the crop 221 grown in the reference farm 21 may be sown with the same seeds as the crop 321 grown in the smart farm 31 .

For example, the processor 320 may receive information about the crop 321 sown in the smart farm 31 (eg, identification information of crops or seeds) and a sowing date from the user. In this case, the processor 320 searches the web or DB for a list of reference farms in which the same seeds as the crops 321 sown in the smart farm 31 are sown and grown, and the results can be provided (displayed) to the user. have.

Also, the processor 320 may obtain a second saturation value of the color of the crop 321 obtained based on the image captured by the camera 313 of the smart farm 31 .

In this case, the processor 320 may obtain second deviation information indicating a difference value between the first chroma value and the second chroma value. Here, when the difference value is greater than or equal to a predefined value, the processor 320 may perform an operation to offset (or reduce) the difference value. That is, the processor 320 may adjust an environmental factor related to saturation adjustment in order to offset the difference value.

And the process of controlling the communication unit to receive environmental information (S510), indicating the difference between the size information and color information of crops grown in the reference farm included in the growth information, and the size information and color information of crops grown in the smart farm It may include a process of obtaining deviation information (S520) and a process of updating the environment of the smart farm based on the received environment information and deviation information of the reference farm (S530).

The above-described operation method of the smart farm control device is a process of determining an environmental factor that needs to be corrected in preparation for the environmental information of the reference farm, based on the deviation information, and generating an update value for changing the numerical value of the environmental factor that needs to be corrected may further include.

In addition, the above-described operating method of the smart farm control apparatus may further include a process of generating current environment information of the smart farm by reflecting the update value in the received environment information of the reference farm.

In addition, the operation method of the smart farm control device described above is based on the difference value between the date when the seeds of crops were sown in the reference farm and the date when the seeds of the crops were sown in the smart farm. The method may further include a process of determining a duration to be set and maintained in the farm, and a process of controlling the current environment information of the created smart farm to be set in the smart farm and maintained for the determined duration.

On the other hand, in addition, the operation method of the smart farm control device described above is based on the comparison value of the process of controlling the communication unit to receive the soil property information of the reference farm and the received reference farm soil property information and the smart farm property information. Thus, it may further include the process of setting the current humidity of the soil of the smart farm.

On the other hand, the operating method of the smart farm control apparatus using the mesh network according to various embodiments of the present invention described above is implemented as a computer-executable program code and stored in various non-transitory computer readable media. It may be provided to each server or devices to be executed by the raw processor.

As an example, the process of controlling the communication unit to receive growth information and environmental information from the control device of the remote reference farm in which the same seeds as the seeds of the crops sown in the smart farm are sown, the crops grown in the reference farm included in the growth information update the smart farm environment based on the process of obtaining deviation information indicating the difference between the size information and color information of the crop grown in the smart farm and the environmental information and deviation information of the reference farm grown in the smart farm A non-transitory computer readable medium in which a program for performing the process is stored may be provided.

The non-transitory readable medium refers to a medium that stores data semi-permanently, rather than a medium that stores data for a short moment, such as a register, cache, or memory, and can be read by a device. Specifically, the various applications or programs described above may be provided by being stored in a non-transitory readable medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.

While the embodiments of the present invention have been shown and described, various changes in form and details may be made by those skilled in the art without departing from the spirit and scope of the present embodiments as defined by the appended claims and their equivalents. you will understand that you can
