Abstract
As a major rice-producing country, China's rice yield and quality are critical to food security and
livelihood protection. Rice diseases and pests have become a key constraint on rice production, reducing
both yield and quality and seriously affecting farmers' income and food supply stability. To realize accurate
prevention, real-time monitoring and scientific management of rice diseases and pests, and overcome
the low efficiency, poor accuracy and complex operation of traditional monitoring methods, this paper
designs an intelligent diagnosis system for rice diseases and pests based on the Keras model and Internet
of Things (IoT). The system integrates lightweight edge computing devices, UAV inspection terminals
and environmental sensors, taking the lightweight Keras deep learning model as the core to achieve rapid
identification and accurate diagnosis. With IoT and edge intelligence, it realizes real-time collection,
monitoring and analysis of field environmental parameters such as temperature, humidity and light
intensity, supporting intelligent monitoring, data recording and dynamic management throughout the rice
growth cycle. The system forms a complete digital and intelligent monitoring and diagnosis scheme with
standardized processes, providing efficient and scientific management support for farmers and effectively
improving the prevention and control efficiency of rice diseases and pests.
