오픈소스 기반 MCU의 농업적 활용성 연구

Abstract

With the growing interest in smart farms that combine ICT technology and agriculture around the world, research related to smart farms has been activated in Korea. However, it is a reality that even the most basic first-generation smart farm is difficult to introduce because it has the disadvantage that the initial cost is burdened and A/S is difficult for farms to introduce smart farms. Since most of the smart farm systems commercialized in Korea are expensive PLC-based systems that are inefficient for facility agriculture, we attempted to develop a smart farm model using an open source based MCU that is cheaper and easier to handle. This system can control the environment of the house through remote control of agricultural equipment such as air circulation fan.It built its own web server and database using open source software, and the control board transmits and receives data through WiFi communication. In addition, data can be transferred smoothly through PHP. Since the system structure is simple, if only the software source code is tailored to the farmhouse environment, it can be a farm-customized smart farm system for only the functions that the farmhouse wants. As a result of demonstrating the system at a facility house that grows blueberries, the introduction cost was significantly reduced compared to commercially available smart farms, and the satisfaction of the farmers was high. As MCU performance continues to improve around the world, it is expected that low-cost smart agriculture can be realized with low cost and simple configuration when an open source based system is developed.
