탄소중립과 디지털전환에 대응하는 농업용 UGV의 특허분석

초록

Diesel engines, which have been used as major power sources for agricultural machinery, have large low-speed torque, are resistant to moisture, and have simple structures such as no ignition system, which have few failures and advantages in maintenance. However, major developed countries around the world are gradually strengthening their drive for decarbonization through energy transition for carbon neutrality, agricultural machinery cannot be an exception to this trend. Along with the power source of eco-friendly agricultural machinery for decarbonization, autonomous platform based on digital transformation technology is also emerging as an important core technology. In this paper, published and granted patents since 2001 were analyzed to analyze the power sources of agricultural machinery and technology trends related to digital transformation. The classification was divided into digital transformation, special-purpose mobile platform, and low-and-zero carbon technology, and each technology was subsequently divided into three to four detailed technologies. This analysis targeted the US, Japan and Europe along with Korea, and major competitors of each target country were also analyzed. As a result, target technologies were analyzed in the early development stage from the perspective of the technology growth stage. Therefore, related R&D investment are required to secure global competitiveness and lead related markets.
