Abstract

The invention relates to a water-saving control method. The water-saving control method comprises the steps that monitoring data about the inlet pressure value, the outlet pressure value and the instantaneous flow of a regulating valve are obtained; the monitoring data are preprocessed, and preprocessed data are obtained; according to the preprocessed data, a response coefficient delta opening between the flow and pressure parameters is calculated by combining an opening calculation model of the regulating valve and a preset opening value; the opening calculation model is trained according tothe preprocessed data to optimize the response coefficient, the optimized response coefficient is given to the opening calculation model, and the trained opening calculation model is obtained; and anideal opening value of the regulating valve is calculated according to the trained opening calculation model, and then the opening of the regulating valve at the next moment is predicted through a prediction model algorithm by combining the ideal opening value. According to the water-saving control method, the opening calculation model can be dynamically adjusted, and the water-saving effect is obvious.

Description

technical field [0001] The invention relates to the technical field of water-saving control, in particular to a water-saving control method. Background technique [0002] Water is the source of life, the key to production, and the foundation of ecology. The importance of water is self-evident, but water is not inexhaustible. Therefore, saving water is the responsibility and obligation of every citizen. While improving citizens' self-awareness of water conservation, how to achieve the purpose of water conservation through technical means is also an important technical bottleneck that needs to be broken through. [0003] In the regional water supply process, the conventional method is to control the water flow in the pipeline through the valve, and open the valve at ordinary times to ensure the water consumption of users. [0004] With the in-depth development of technology, there have been some methods through PID to control the opening of the valve to control the water flo...
