1. Product Overview
With the development and change of the climate, the negative impact of sand and dust storms on the environment has seriously endangered the living environment of human beings. Therefore, the monitoring and early warning of sand and dust storms have become very important in meteorological observation activities. The intelligent cloud network digital high-precision wind erosion automatic meteorological station integrates high-precision comprehensive collection, diversified communication, site data early warning, monitoring point active alarm to the superior and other functions, which is suitable for monitoring the trend of wind and sand movement in nature and soil wind erosion, soil sandy and desertification monitoring, soil organic matter (SOC) erosion and other harsh environments, automatically record the starting time and intensity of the precipitate erosion, the cumulative amount of the precipitate in the wind section with time, record the meteorological parameters in the relevant process, and analyze the composition of the wind erosion, etc. Provide accurate meteorological data for local relevant water and soil departments, which can effectively improve the ecological environment and agricultural production conditions, reduce drought, wind and sand, sand and dust storms and other natural disasters, promote the adjustment of industrial structure, promote agricultural increase and farmers' income increase, and also provide relatively reliable scientific basis for the formation and change law of wind and sand landform.
Second, Working Principle
This system is an automatic sand collection system, which uses a weighing sensor to automatically record time and the amount of wind and sand collected; theH11-LIN type wind erosion sensor is used to measure the momentum flux of sand, and the two output quantities are kinetic energy and the number of impacting particles, the principle is that the charge quantity is proportional to the kinetic energy of the particles. The relationship between the charge, voltage and capacitance is Q=CV., V=Q/C. The voltage fluctuation in the capacitor is like an irregular staircase, and the kinetic energy of a single particle will affect the charge on each step of the staircase. When the voltage applied to the capacitor exceeds the internal reference voltage, the capacitor will repeat this process. A fast discharge pulse is converted into a particle energy value display, and this energy value is an accumulated value of the energy of a single particle. At the same time, meteorological factors such as wind speed, wind direction, temperature and humidity, radiation can also be monitored and recorded.
