[0002] Piped drinking water systems are gradually becoming an important option for upgrading drinking water in both new and old buildings. These systems need to ensure the safety of drinking water from preparation to consumption through water purification, pipeline transportation, and terminal supply. However, existing piped drinking water systems have the following problems in actual operation: First, water quality monitoring coverage is insufficient and maintenance is inconvenient, and there is a lack of effective monitoring of branch pipelines.

When the user's remaining water volume is insufficient, the water quality monitoring is abnormal, or system maintenance is required, the operator can send a command through the cloud server, which is transmitted to the remote solenoid valve 405 via the concentrator to control it to close and cut off the water supply to the user, without the need for manual on-site operation. The water volume alarm component 406 is installed on the IoT remote water meter 403. The inner wall is used to monitor the remaining water volume or water consumption per unit time in the IoT remote water meter 403. When the remaining water volume is lower than the preset threshold, or the water consumption is abnormally high, indicating a possible leak, the water volume alarm component 406 generates an alarm signal, which is transmitted to the concentrator via a wired connection. The concentrator then uploads the signal to the cloud server, triggering a warning notification to the operator and a reminder message to the user. The remote solenoid valve 405 is installed on the pipeline between the IoT remote water meter 403 and the shut-off valve 404. The water volume alarm component 406 is installed on the inner wall of the IoT remote water meter 403 and is electrically connected to the concentrator.

After that, the cloud server will send the water volume data to the IoT remote water meter 403. Water usage operation: When a user needs water, the coil 411 of the anti-pollution structure 407 is energized, driving the piston 410 to open the through hole, and then the shut-off valve 404 is opened. The drinking water is delivered to the user's water end through the meter control component 401, and the IoT remote water meter 403 measures the water consumption in real time. When water usage ends: The user closes the shut-off valve 404 (or the user's faucet), the coil 411 of the anti-pollution structure 407 is de-energized, the elastic element 414 pushes the piston 410 to reset, the sealing element 413 seals the through hole, the water in the outlet section is drained, and the unused drinking water flows back to the main return pipe 202 through the secondary return water branch pipe 206 and enters the circulation.
