Abstract:

New generation technologies such as IOT, cloud computing, big data, blockchain and artificial intelligence provide a new path and model for the upgrading and transformation of traditional agriculture and the development of smart agriculture. Taking the intelligent development of walnut industry in Fengqing County, a demonstration county of "one county and one industry" in Yunnan Province as the research object, and aiming at solving the key data monitoring and application needs of walnut planting base environment, aiming at the problems of weak infrastructure, difficult power supply network, difficult data security and difficult data acquisition and monitoring of walnut base in mountainous areas, this paper carried out the research based on STM32 technology, It is widely applicable to the research, design and implementation of base environmental monitoring IOT system for walnut and other crops in mountainous and remote areas. The system is based on Nb IOT technology, 4G technology, solar power supply and blockchain technology to realize data integration with Alibaba cloud IOT platform, from the overall system architecture, main control module, communication module, power supply module, data transmission module, blockchain design and deployment We have carried out research on data security and data visualization, designed and developed the environmental data monitoring system of mountain walnut base based on the Internet of things, deeply integrated the blockchain technology with the Internet of things technology, built a data security chain using Baidu open source blockchain xuperchain, realized the real-time uploading of all monitoring data, and ensured the authenticity, reliability and tamperability of the data. Through a large number of tests and application demonstrations in four core walnut producing areas in Fengqing County, it is proved that the environmental Internet of things monitoring system of walnut base based on STM32 has high availability and achieved good results, which provides data support and reference for promoting the decomposition, reconstruction and evolution upgrading of walnut industry chain, value chain and supply chain, and creating a smart, green and ecological walnut brand.

Key words: walnut, base environment, STM32, Alibaba cloud, IOT, NB-IoT, blockchain monitoring system
