(From the methodological point of view, the research and development of wireless sensor network based on intelligent micro-nodes is summarized. The definition of the wireless sensor network based on intelligent micro-nodes and points is given, and the system structure is introduced from the structure of the network system and the structure of intelligent micro-nodes and points. Its research value and research hotspots, as well as key technologies such as energy and efficiency, safety and reliability, are analyzed, and the system-level and node-level evaluation objectives are given. R&D is summarized.)
