The processor evaluates a health state of crops and a progress of crop growth by applying a machine learning algorithm to the sensor data using an artificial intelligence (AI) unit. The processor further acquires weather forecast data and market demand data and performs a comprehensive analysis to generate an optimal farm work plan. Based on an analysis result produced by the AI unit, the processor controls agricultural machines including at least an irrigation system, a pesticide spraying drone, and a harvesting robot to automate farm work.
