Description

technical field [0001] The invention relates to an industrial control system and method, in particular to a water supply control method and system. Background technique [0002] In tap water treatment, due to the complexity of the urban pipe network and the uncertainty of changing water conditions in the water supply link, the range of water supply load varies greatly, making the operation of water supply equipment unstable and energy-consuming. At present, domestic research on water supply load forecasting mainly focuses on traditional forecasting principles and methods, such as exponential smoothing, time series analysis and regression analysis. Traditional forecasting methods require an explicit forecasting model of water supply load composed of certain influencing factors. Since the urban water supply system is a complex large system with coexistence of uncertainty, nonlinearity and time-varying nature, establishing an explicit forecasting model of water supply load not...

AI Technical Summary

Problems solved by technology

Since the urban water supply system is a complex large system with coexistence of uncertainty, nonlinearity and time-varying nature, establishing an explicit forecasting model of water supply load not only requires a large amount of historical data of water supply load, but also requires a large amount of relevant data, including temperature, humidity and population, etc., the search and recording of these data is particularly cumbersome, and it is difficult to ensure the integrity of the obtained data. Therefore, it is not easy to obtain an accurate explicit prediction model by using traditional prediction methods. The accuracy of the prediction model is difficult to guarantee, and it lacks adaptability. sex and flexibility

In addition, the accuracy of traditional forecasting methods based on stochastic processes and mathematical statistics principles is not ideal, and the forecasting accuracy is not high.
