Abstract
Due to the large agricultural population and limited arable land area, China's agriculture has always been based on small farms. However, with the gradual intensification of population aging and the advancement of urbanization, the agricultural labor force is now decreasing. In the future, China's food security will face the challenges of "who will cultivate land" and "how to cultivate land". One of the implementation paths to solve this problem is unmanned farm technology. This article systematically elaborates on the concept and technical architecture of unmanned farms, as well as key technologies such as infrastructure, operating equipment, data monitoring systems, and control service platforms, through the technical practice of unmanned farms in Jiading District, Shanghai. It deeply explores the development of unmanned farms and has certain guiding significance for the development of unmanned farms.
