Liquid pressure conduit leak detection device

Abstract

The invention discloses a liquid pressure conduit leak detection and location device which comprises two piezoceramics crystal acceleration transducers used for acquiring signals, two transmitters used for transmitting signals, a receiver used for receiving data and transmitting the data to an upper computer and the upper computer processing data at a terminal; wherein, the two piezoceramics crystal acceleration transducers are attached at the two ends of the tested conduit; each of the transmitters comprises a signal automatic magnification factor option circuit, a signal dynamic range automatic gain control circuit, a filter amplifying circuit and a wireless transmitter unit; the receiver includes a wireless receiving unit used for demodulating and amplifying the received signal and a signal processing circuit that has the function of interface and realizes the communication between the receiver and the upper computer. The invention can solve the problem of leak detection and location for a liquid pressure conduit, and provides the conduit leak detection and location device having low cost, convenient use and reliable performance.

Description

technical field [0001] The invention belongs to a liquid pressure pipeline leak detection and leak location device, and specifically relates to an audio noise analysis and processing technology of a liquid pressure pipeline. Background technique [0002] At present, there is no equipment dedicated to leak detection and leak location of liquid pressure pipelines in my country. Under the situation of increasing scarcity of water resources, improving the utilization rate of water supply is the top priority of water conservation. In the water pipeline, due to the quality of the pipeline, construction factors, geological conditions and use time and other factors, leakage problems occur from time to time. Usually, due to the untimely detection, the leakage is only discovered when a large amount of leakage occurs, and a lot of water resources have been wasted before it is discovered. In order to reduce the leakage rate of water supply, developing a leak detection and leak locatio...

Problems solved by technology

[0003] At present, the leak detection equipment in my country is basically based on the human ear listening to the road surface, which requires people to judge the sound signal subjectively. The disadvantage of this method is that the effect is greatly affected by people's subjective influence and judgment, especially when dealing with complex, Detection in harsh environments (such as deeply buried pipelines) and complex pipelines (such as multiple branches) is its weakness, and the positioning accuracy is not high
