Automatic pipeline distribution detection system and method based on sound wave transmission

Abstract

The invention discloses an automatic pipeline distribution detection system and method based on sound wave transmission. The system comprises a transmitter and a receiver; the transmitter is arrangedin a pipeline port and is used for generating sound waves and transmitting the sound waves in the pipeline port; at least three receivers are arranged on the ground, at least one receiver is not collinear with any two other receivers, and the receivers are used for receiving sound waves, determining the position of a pipeline according to the propagation direction and intensity of the sound wavesto generate a distribution diagram of the pipeline and determining a leakage point position of the pipeline according to the intensity of the sound waves.

Description

technical field [0001] The invention belongs to the field of automatic pipeline distribution detection for acoustic wave transmission, in particular to an automatic pipeline distribution detection system and method based on acoustic wave transmission. Background technique [0002] At present, the indoor plumbing diagrams of many old houses are lost, and it is difficult to determine the specific location of the pipes. At the same time, the pipes are in disrepair for a long time, and leaks are prone to problems. The leaks are not easy to find during application, resulting in liquid leakage in the pipes and wasting resources. Therefore, if you want to detect leaks, you must first determine the specific location of the indoor pipeline, and then specifically detect the location of the pipeline leak. The current method for detecting the position of the pipeline includes the method of transmitting and receiving high-frequency pulsed electromagnetic waves, but the method is complica...

Problems solved by technology

[0004] Among the existing three methods, the first and second methods are costly and except for the method based on distributed optical fiber, the rest of the methods do not have real-time detection capabilities; the third method is the most commonly used method based on negative pressure waves with small leakage and slow leakage sensitivity and poor positioning accuracy, overcome the disadvantages of poor disturbance capability of the operation station and high false alarm rate
