Prediction of urban water supply quality based on multi-sensor technology

Abstract：The quality index such as pH value, turbidity etc, are monitored by urban water supply system.When the quality index surpasses the limitation, the response system will handle the treatment effectively to against accident and ensure the water safety.While, the water in pipelines has random fluctuation, it is difficult to find the problem with limit value monitoring.By applying the method of multivariate data analysis and based on multi-sensor technology, the change trends of water quality can be forecasted.Accroding to the trends type, the corresponding measures are designed.The results indicate that the actual process can be forecasted effectively.
