Forecast of weak electrical signals in Dahlia pinnata by neural networks

摘要

Signals of dectries in Dahlia pinnata were tested by a touching test system of self-made double shields with platinum sensors and tested data of electrical signals denoised by the wavelet soft threshold and also using Gnusslan radial base function (RBF) as the time series at a delayed input window chosen at 50. An intelligent RBF forecasting model was set up to forecast the information fusion of weak signals in plants. Results show that it is feasible to forecast variation of plant electrical signals for a short period. In the future, the forecast data can be used as the preferences for an intelligent automatic control system based on the adaptive characteristic of plants both the greenhouse and /or plastic lookum to achieve the energy saving on agricultural and horticultural production.
