Research On Environmental Monitoring System Of Inner Mongolia Desertification Grassland Based On WSN

Through hard work,the desertification of grasslands in northern China has been effectively controlled.However,we should pay more attention to the root causes of desertification.In addition to over-grazing,less rainfall,and excessive waste of water resources,the activities of grasshoppers such as locusts also accelerate grassland desertification to some extent.Based on the research targets of early warning and monitoring models for grassland locust disasters in Inner Mongolia,this paper focuses on the monitoring technology of grassland locust living environment and locust outbreak quantity,providing basic assessment data for future research on the relationship between locust outbreaks and environmental conditions,and providing basic evaluation data for constructing locust disaster early warning and monitoring models.In this thesis,a WSN environment sensing node composed of a variety of sensors and cameras is designed to collect environmental information and image information.The data information is then processed and transmitted wirelessly to the WSN terminal.According to the amount of data collected by the system,the acquisition node with STM32F429 as the core is designed to collect the environment and real-time image information in a fixed area with multiple sensors to the node memory card.In the form of wireless transmission,the data aggregated by the node memory card is packaged and sent to the WSN terminal station to realize monitoring of wind speed,direction,precipitation,temperature and humidity,light intens ity,image information,and other information,and to provide data for later research.basis.This design finally achieved accurate collection of multiple environmenta l information and timing acquisition of clear image information.It also designed a simple data view us ing C#,inquired the terminal interface,and basically reached the expected design requirements.
