Agriculture is one of the basic industries of human society, but the traditional agricultural production methods are facing a series of challenges and problems, such as climate change, soil quality, pest control and so on. In order to improve agricultural production efficiency, reduce production costs and protect the environment, the intelligent system of agricultural greenhouse based on voice interaction came into being. This project uses the Internet of Things, artificial intelligence and voice recognition technology to realize the functions of environmental data collection, intelligent irrigation, intelligent fertilization, intelligent light supplement, remote control, and scene automatic control of the smart greenhouse, and can interact with farmers through natural language, Provide them with real-time information and guidance on agricultural production. According to the actual situation of the farmland, crop planting suggestions can be provided, and the current crop planting soil environment details and historical records can be recorded to help them better manage and track the crop growth process, and the work of greenhouse equipment can also be controlled by voice.
