A method for identifying and locating burst pipes in water supply systems

Abstract

The invention discloses a pipe burst identifying and positioning method for a water supply system water delivery pipe. The burst situation of the water supply system water delivery pipe is identifiedin time through real-time acquisition of pressure and flow data in the pipe and real-time monitoring of a water company dispatching mechanism, and positioning work of a pipe burst place is performed.By utilizing a pipe burst positioning method established according to the hydraulic characteristics of the water supply system water delivery pipe, the pressure and flow data transmitted back by an online monitoring system of a water supply system are acquired in real time, whether a pipe burst accident occurs in the water delivery pipe or not is identified through real-time analysis, quick positioning and calculation are performed, the capability of quickly responding to pipe burst is improved, a water supply company is guided to regulate water supply, field staff is dispatched for repair, and the safety of a water-transportation project is guaranteed.

Description

technical field [0001] The invention relates to the field of information application of water pipes, in particular to a burst pipe location method based on SCADA monitoring data. Background technique [0002] The water delivery pipe of the water supply system is widely used in water supply projects, which ensures the continuity and safety of the entire water supply system, and is also a prerequisite for water supply scheduling and adjustment in water plants. Due to the aging of the pipeline, artificial construction and environmental changes, the water pipeline of the water supply system will have different degrees of leakage after running for a period of time, and serious pipe burst accidents will occur. Once the pipe burst phenomenon occurs, it will not only cause economic losses, but also cause damage to urban infrastructure, affect the normal life of residents, and cause negative social impacts. The goal of the location of the pipe burst in the water supply system is to ...

Problems solved by technology

The manual inspection method has a large amount of work, low efficiency, lags behind in time, and cannot provide timely feedback on the leakage of the pipeline; at the same time, due to the limited propagation distance of sound waves in domestic water supply pipelines, the environmental noise interference is large, which greatly affects the accuracy of manual inspection. sex

Although the negative pressure wave method has high accuracy, in order to obtain the accurate time difference between the pressure wave and the reflected wave, it needs to be monitored by high-precision high-frequency sensors, but it is almost impossible to use it in actual engineering due to the limitation of site conditions and economic budget.

In the actual situation, low-frequency quasi-steady-state pressure and flow monitoring instruments are often used, and the accuracy of the instruments is difficult to meet the accuracy requirements for positioning
