【Abstract】 A long distance water pollution monitoring system is introduced, which mainly consists of an ultraviolet spectrophotometer and a computer, and is based on artificial neural network. The structure of the system and the design of the multiple feedforward neural network used for identification of spectrogram of wastewater are discussed. Precision of the networks with different numbers of hidden layer nodes is analyzed. Long distance water can be monitored by the system, and the judge of the water quality can be made through the identification for the spectrogram of wastewater by neural network, without the content measure of pollutants in wastewater. The system can be also used in the analysis of infrared or visible light spectrograms.更多还原
