Description

technical field [0001] The invention relates to a hydrological monitoring wireless sensor node device based on a real-time embedded CPS, and belongs to the technical field of hydrological monitoring equipment. Background technique [0002] Due to the uneven distribution of water resources in my country, complex topography, diverse climates, and unbalanced economic development, frequent floods and droughts have occurred in my country, which have brought huge losses to human life and economic development. Hydrological work is the foundation of water conservancy work, and hydrological survey is an important index to measure water conservancy work. The accuracy and real-time performance of hydrological information detected by the hydrological monitoring system directly affects personal and property safety, reservoir flood control safety, and agricultural irrigation. [0003] In order to prevent floods and reduce economic losses caused by floods and droughts, our country has inve...
