Microenvironment information acquisition and processing in farmland water potential soft-sensing

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 time-spatial 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.
