Description

Smart Farm System and Control Method Using Insect Rearing The present invention relates to a smart farm system and control method utilizing insect rearing, and more specifically, to a smart farm system and control method utilizing insect rearing that supplies organic waste generated after plant cultivation as feed for insects and uses excrement generated during the insect rearing process for plant cultivation to create a cycle. Recently, various farming and aquaculture methods are being utilized due to the decrease in food resources caused by global warming and environmental pollution problems resulting from the use of chemical fertilizers. In particular, interest in aquaponics, which allows for the simultaneous operation of fish farming and hydroponics, is growing. Conventional technology regarding such aquaponics has already been disclosed in Korean Registered Patent Publication No. 10-1507057 (Title of Invention: Urban Biofloc Aquaculture System Using Aquaponics, Mar. 24, 2015). Conventional technology is characterized by combining rearing water drained from an aquaculture tank with a plant cultivation system to produce aquatic organisms and agricultural plants. However, while there is a growing demand for technologies to cultivate edible resources other than aquatic organisms and agricultural plants to address the problem of gradually depleting food supplies, specific technologies have not yet been presented. Recently, research and development on edible insects has been actively underway, and edible insects are being mass-produced through mass production systems by businesses and then supplied through distribution networks. However, there are issues regarding environmental pollution arising from the disposal of large quantities of excrement generated during the process of raising large numbers of edible insects, as well as the problem of requiring the cultivation and production of additional crops to supply the feed for raising the insects.
