Smart agriculture has become a major trend in the development of modern agriculture.The transformation of agriculture by using artificial intelligence and big data can effectively solve the current problems such as weak information foundation,low quality of agricultural machinery operation,fragmentation of arable land and so on.The designed smart agricultural system combines artificial intelligence technology with agricultural production,and constructs web front-end and back-end management systems based on SpringBoot+React architecture,which integrates crop planting area management,growth situation monitoring,remote sensing image processing and sensor data monitoring and analysis modules.It can monitor agricultural information in real time and provide important support for crop precision management and field operations.The system further promotes the application of remote sensing technology and deep learning technology in agriculture,has real-time and expansibility,and therefore can be applied to agricultural production of different scales.
