Systems, methods, and media for emergency water quality management in smart city pipe networks based on internet of things large models

A method for emergency water quality management in a smart city pipe network, wherein the method is implemented by an emergency water quality management platform of a system for emergency water quality management in a smart city pipe network based on an Internet of Things large model, and the method comprises:

• in response to a water quality contamination point occurring within one or more pipe network regions, determining a critical contamination region based on a contamination probability of the one or more pipe network regions and the water quality contamination point;
• determining a contamination source region based on water quality monitoring data, hydraulic monitoring data, and pipe network data of a plurality of monitoring points within the critical contamination region;
• determining a plurality of first valves based on source hydraulic data of the contamination source region, wherein the plurality of first valves are downstream valves on pipe sections at connections between the contamination source region and other pipe network regions;
• and
• generating a first valve control instruction based on the plurality of first valves, and controlling the plurality of first valves within the contamination source region to close based on the first valve control instruction.
