About.

As functional mushrooms have been discovered to increase the body's immunity and anticancer effects, the demand for functional mushrooms is increasing amid increasing interest.

Korea was once one of the major exporters of mushrooms along with Taiwan and the Netherlands, but in terms of technology development and cultivation conditions for mushroom cultivation, Korea is inferior to that of Japan or Europe. Recently, as China participated as an exporting country, exports declined due to falling behind in international price competition. Has become.

Unlike ordinary crops, these mushrooms are cultivated only in a small number of farms that meet these conditions because environmental conditions such as temperature, humidity, ventilation, and light in the cultivation room must be closely adjusted.

In addition, when mushrooms are cultivated, oxygen is consumed and gases such as carbon dioxide (CO ₂ ) and ammonia (NH ₃ ) are produced. These gases play a role in maturing the mushrooms and cause the appearance of the mushrooms, leading to deterioration in quality. Therefore, proper air quality management is also important.

Since the complexity of these cultivation conditions inevitably leads to an increase in the cost for facility construction and operation, it was still inevitable to apply natural ventilation to manage the air and humidity inside the cultivation room, and problems of low efficiency and pollution were pointed out. Due to the difference between the growth conditions and the growth conditions of the mushrooms, the removal and cultivation of mushrooms was carried out in a separate space, and there was trouble in the movement of the mushrooms.

Accordingly, in order to increase the domestic demand and export of functional mushrooms, the production of qualitatively improved mushrooms and cost reduction are demanded, and while high-efficiency functional mushroom cultivation is being promoted in Korea, a customized system is urgently needed.

At this time, the algorithm set in the interlocking control unit 6 may basically reflect a control value reflecting an experiment reflecting the characteristics of mushrooms grown, but precise control reflecting detailed factors of the smart farm may be required. Environmental measurement values can continuously collect and analyze control values so that optimal control values can be adjusted.

To this end, the database DB stores and collects a measurement result of the cultivation environment monitoring unit 1 corresponding to a control command of the interlocking control unit as well as an image captured by the camera unit 15 over time.

In response to this, the analysis module 7 analyzes the information stored in the database DB, and reflects the analysis result to correspond to the photographed image of the cultivation environment monitoring unit 1 and the camera unit 15. The control value of the interlocking control unit 6 is corrected. Typically, in response to the specific control of the interlocking control unit 6, when the change in the cultivation environment monitoring unit 1 is not at a desirable level or is insignificant, the control value is changed within a predetermined range to change the measured value of the cultivation environment monitoring unit 1 Monitoring and finding the optimum control value. In addition, the image captured through the camera unit 15 may be analyzed by comparing the size of the mushrooms to obtain information on a medium determined to be fast or slow to grow, and to find an optimum control value.
