Multi-channel Soil Wind Erosion Data Automatic Acquisition And Processing System

Real-time monitoring and gathering the soil wind erosion environmental datais an important soil wind erosion research content. In this article, in view of the problems existed in present soil wind erosion acquisition and processing system, such as single point measurement, cable data transmission, large volume test equipment, complex connection of measurement circuit, unable network measurement; using the microcontroller STC12C2052AD and wireless data transmission module UTC4432B as the core processors, a multi-channel soil erosion data automatic acquisition and processing system is designed based on LabVIEW2010. The10channels soil erosion data (air temperature, humidity, atmospheric pressure, wind speed, and wind erosion et.c) can be the cycle acquisition, wireless transmission and real-time processing within1s by the System. A microcontroller is used to. drive the sensor group of the measured point to process and packet the collected data. Achieve the transmission and reception of data packets by using a pair of wireless data transmission module. Use the PC software programmed by LabVIEW2010for reading, processing, and storage of data packets. The system has the advantages of simple hardware structure, low cost, stable work, easily operation, and its effective transmission distance is up to600m, so it can complete real-time monitoring task of the small area soil erosion data effectively and stably.
