The invention discloses a water pipe path planning method with a monitoring system. The monitoring system comprises a plurality of water pressure detecting devices arranged in a water pipe, each waterpressure detecting device comprises a speed measuring module used for detecting flowing water speed, a water pressure monitoring module, a booster pump control module, a processor and a communicationmodule; the communication module processes a received command of a central computer and sends the command to the booster pump control module, and the booster pump control module can control corresponding water pressure; after the central computer calculates the optimal distribution layout path, node information in the path is sent to an engineering command center, and the engineering command center sends a detailed operation instruction to a specific worker; and then water pressure adjustment is performed according to real-time water pressure information of the water pipe in a large communityto ensure that water pressure can reach a threshold, thereby ensuring that residents at high levels can drink high-quality drinking water.
