Leveraging drones, unmanned vehicles, mobile sensors, and big data platforms, a new generation of intelligent agricultural systems is built—characterized by a high level of informatization, efficient operation and maintenance, and low costs. Front-end sensing devices collect real-time data on the status of farmland, crops, and livestock, as well as environmental conditions. Through long-term data analysis via the big data platform, the most accurate agricultural profile analyses and early warning insights are generated. Unmanned equipment is then deployed to carry out tasks such as fertilization, pesticide application, and security patrols.
