The present invention relates to a customized smart farm system and a method for providing the same, and more particularly, to a smart farm control system that selectively installs facilities necessary for user cultivation farms and configures smart farm control means for customized functions, And a method of providing the smart farm system.

Recently, research and development on agricultural technology has become active under the government's advanced technology of farming technology. Accordingly, a number of smart greenhouses have been developed and constructed. Unlike existing greenhouses, these smart greenhouses can manage the growth of crops through various types of sensors and farm facilities and operating programs to control them.

However, as the farming environment of traditional farmhouses in rural areas deteriorates, the spread of vinyl houses that can grow stable crops of high-income crops is rapidly increasing, but the spread of smart farms is slowing down.

According to the results of surveys conducted recently on farm households, major obstacles to the spread of smart farms are the high cost of installation, insufficient follow-up management of installers, frequent breakdowns, and lack of management skills.

Therefore, in order to expand the spread of SmartPharm, it is important to develop highly reliable sensors and systems that can withstand long periods of time in a poor vinyl house environment, and it is necessary to plan to lower the high facility cost burden.

For example, when the window is not opened or closed when a signal for controlling the opening and closing of the window is not transmitted, the presence or absence of the operation of the motor is detected using the current and voltage detection value applied to the motor, Can be detected.

The correcting unit 340 performs a correcting function corresponding to the failure state detected by the failure detecting unit 330.

In addition, the atmospheric environment information of the cultivated farm is measured and transmitted to the central processing unit 110 by measuring the wind direction, the wind speed, the solar radiation amount, the rainfall amount and the like of the external environment in the atmosphere integrating means 140.

Next, a step of transmitting a control signal of the facility driving load corresponding to the measured atmospheric environment information and crop environment information is performed (S640). Here, if the moisture of the soil is detected to be below the reference value in the crop environment information transmitted from the sensor means 130, a control signal is transmitted to drive the sprinkler to supply water, or when the sensor means 130 determines that the carbon dioxide concentration is above the reference value It is possible to operate the driving load for ventilation but ventilation can be performed by using window opening / closing without using the ventilation driving load by comprehensively using the wind direction and wind speed information by reflecting the atmospheric environment information. That is, the central processing unit 110 uses the atmospheric environment information and the crop environment information to comprehensively determine the conditions necessary for the crop of the cultivation farm, and controls the respective loads to be driven.

In operation S650, the respective facility drive loads are operated corresponding to the transmitted control signals.
