Smart agriculture is an advanced stage of agricultural production, which integrates emerging technologies such as Internet, mobile Internet, cloud computing and Internet of Things. It depends on various sensor nodes (environmental temperature and humidity, soil humidity, carbon dioxide, images, etc. ) and wireless communication network to realize intelligent perception, intelligent early warning, intelligent decision-making, intelligent analysis and online guidance of agricultural production, and provide accurate planting, visual management and intelligent decision-making for agricultural production. "Smart agriculture" is a comprehensive application of information technologies such as cloud computing, sensor networks and 3S in the agricultural field, which has achieved more complete information support, more thorough agricultural information perception, more concentrated data resources, wider interconnection, deeper intelligent management and control and more intimate public services. The integration of "smart agriculture" with modern biotechnology, planting technology and other high-tech technologies is of great significance to building world-class agriculture.
At present, there are many smart agricultural companies in China, among which Henan Yun Fei Science and Technology Development Co., Ltd. and Hebi Jiaduoke Industry and Trade Co., Ltd. have developed well. Beijing Jiage Tiandi Agricultural Big Data Company and Beijing Paide Ye Wei Technology Development Co., Ltd.; Guangxi Huiyun Information Technology Co., Ltd. is in Guangxi; Sichuan Chengdu Century Ruitong Technology Co., Ltd.; Zhejiang Zhejiang Dingyun Agricultural Technology Co., Ltd.. Some of these companies are good at big data, some are good at hardware development, and some are integrated with software and hardware systems.
