Abstract

The invention discloses a pipeline monitoring system and method based on sound waves. The monitoring system comprises a sound signal obtaining module, a signal transmission module, a signal transmission module, a sound wave monitoring and analyzing platform and a data storage module, wherein the sound signal obtaining module is used for obtaining sound wave signals of a monitoring object in the pipeline system in real time; the signal transmission module is used for transmitting electric signals to the sound wave monitoring and analyzing platform; the sound wave monitoring and analyzing platform carries out conversion, noise reduction and storage on the electric signals, and analyzes the signals after the noise reduction to obtain the operation condition of the monitoring object in the pipeline system; the data storage module is used for storing the electric signals obtained by the sound wave monitoring and analyzing platform and a result processed by the sound wave monitoring and analyzing platform; and real-time continuous on-line leakage monitoring for a pipe network and fluid equipment is realized through a relatively cheap sonic sensor, and the sonic sensor realizes real-timemonitoring for the starting, stopping, faults and other states of the equipment while monitoring the leakage of pipelines and the equipment.

Description

technical field [0001] The invention relates to the field of fluid pipeline monitoring, in particular to an acoustic wave-based pipeline monitoring system and monitoring method. Background technique [0002] Fluid pipelines are an important infrastructure for the survival and development of cities. However, due to problems such as missing files and inaccurate detection, accidents are often caused by cutting pipelines during construction, resulting in serious economic losses and adverse social impacts. Therefore, realizing accurate detection of fluid pipelines has become an urgent problem to be solved in urban development. In particular, the leakage of fluid pipelines for transporting fluids such as water, oil, natural gas, and heating and hot water has become a major factor that interferes with the safety of urban infrastructure such as water supply, gas supply, and heating supply. How to use reliable, safe, and low-cost sensors and their monitoring technology has become th...
