Microenvironment Information Acquisition and Processing in Farmland Water Potential Soft-sensing

摘要

The soft-sensing network for farmland water potential (FWP) is composed of several WSN’nodes designed as acquisition and processing instrument for crop microenvironment information and FWP soft-sensing station. According to the result of secondary variables selection and requirement of data pre-treatment, sensor configuration is done, abnormal data recognition, random noise filtering and timespatial data fusion are executed successively to transform data acquired into the data-in of FWP soft-sensing model. In practical application, the expected effect has achieved.
