Description

Technical Field

[0001] The present invention relates to the technical field of pressure regulation of urban water supply pipe networks, and in particular to an intelligent water supply pipe network pressure control system and method based on dynamic programming. Background Art

[0002] Pressure regulation in urban water supply networks ensures that water pressure remains stable within an appropriate range through reasonable operational control measures. This involves two aspects: the water supply phase and the user phase. In the water supply phase, real-time monitoring of water usage in the system reveals users' maximum water consumption and peak water usage, which are then used to rationally configure water supply pressure. Users in different locations have different water pressure requirements; for example, high-rise buildings require higher water pressure, while residential areas require relatively lower water pressure. By adjusting the water supply pressure, water pressure in each area is properly balanced. However, existing water supply pressure regulation in urban water supply networks cannot dynamically and accurately regulate water supply pressure based on user-side water consumption rates, reducing the reliability of urban water supply management and increasing the cost of urban water supply.

[0003] Chinese invention patent publication number CN106444516B discloses a low-pressure control system and method for the terminal end of an urban water supply network. The system utilizes data acquisition devices, remote transmission equipment, a monitoring center, a data storage terminal, and a feedback controller and control devices. Data monitoring and remote control are performed on the upstream, target, and adjacent networks, while the pressures of the three types of networks are uniformly adjusted and controlled in conjunction with the various control devices. This ensures normal water supply to low-pressure areas within the network as a whole. The feedback controller then limits the pressure in the target area, improving the overall safety and reliability of the water supply network. However, the above technical solutions cannot achieve online intelligent control of water supply pressure in urban water supply networks. Summary of the Invention
