[0002] The control of domestic water supply in the factory area is aimed at the domestic water supply system in the industrial park or enterprise, through reasonable management and technical means, to achieve the purpose of effectively controlling the water supply and improving the efficiency and stability of the water supply system. In modern industrial parks or enterprises, the domestic water supply system is usually decentralized, diverse and dynamic, involving different water use stages and rich types of water use periods, and the water demand in different water use stages is also different.
[0003] However, traditional water supply control methods lack the ability to predict future water use conditions and cannot make adjustments in advance, which easily leads to waste and inefficient operation of the water supply system. At the same time, traditional water supply control methods usually control the water supply based on static rules and cannot make flexible adjustments based on real-time water use conditions, resulting in poor adaptability of the water supply system. In addition, traditional water supply control methods can only regulate a single water demand and lack comprehensive consideration of complex and changeable water use conditions, resulting in poor control accuracy.
