智能供水system：从 “源头” 到 “龙头” 的全流程无人值守方案（节能 + 安全 + 省心版）

1、 Industry pain points

The four core challenges of traditional water supply models constrain efficiency and safety:

1. Traditional rooftop water tank / High level water tanks are prone to breeding algae, insects, and ants, and secondary pollution directly threatens water safety.
2. Manually starting and stopping the water pump and adjusting the valve based on experience are common occurrences “Big horse pulling small car” Or “A small horse pulling a large cart”Serious energy waste and shortened equipment lifespan.
3. Malfunctions such as pipe burst, dry pumping, and overvoltage are difficult to detect in a timely manner, which can easily cause flooding of pump rooms and motor burnout, with a single repair cost of tens of thousands of yuan.
4. In unmanned scenarios such as high-rise residential areas, remote orchards, and nighttime water use, the disposal of leaks and spills is lagging behind, and losses continue to expand.

Make the water pump follow the water demand “Accurate frequency conversion running”Before the malfunction occurs “Proactive warning”Management is thousands of miles away “Real time visualization”Thoroughly solve the inefficiency and risks of traditional water supply.

The direction of data flow is indicated by dashed lines with arrows (data collection in the perception layer→encrypted transmission in the transmission layer→local computation in the edge layer→multi terminal synchronization in the platform layer→output analysis report in the application layer). A legend is added at the bottom to explain the meaning of the color blocks and arrows, visually presenting the collaborative logic of the entire link.
