Vibration pipeline diagnostic system and method
A technology for vibrating pipelines and diagnostic systems, which is used in the analysis of solids using sound waves/ultrasonic waves/infrasonic waves, liquid tightness measurement using liquid/vacuum degrees, and processing detection response signals. It can solve leakage, cannot generate vibration, and the system cannot Detect or identify issues such as problems

Problems solved by technology
The disadvantage of this prior art approach is that the system is completely passive and cannot generate vibrations
Additionally, Lander's system cannot detect developing pipeline weakening and cannot detect future defects or problems in the pipeline
Lander's system cannot detect or pinpoint the problem until the leak develops

Provided is a vibration pipeline diagnostic system (100). The system (100) comprises at least one vibration generator (104) suitably fixed to a pipeline, at least one vibration sensor (107) suitably fixed to the pipeline, and a processing unit (111) communicated with the at least one vibration generator (104) and the at least one vibration sensor (107). The processing device (111) is configured for adopting the at least one vibration generator (104) to vibrate a part of the pipeline, receiving a vibration response of the vibration from the at least one vibration sensor (107), and comparing the vibration response with one or more former vibration responses of the pipeline; if the difference between the vibration response and one or more former vibration responses is greater than a predetermined tolerance, a fault condition is indicated.
Description
[0001] This application is a divisional application of a patent application with an application date of February 22, 2007, an application number of 200780051697.3, and an invention title of "Vibrating Pipeline Diagnosis System and Method". technical field [0002] The present invention relates to a pipeline diagnosis system and method, and more particularly, to a vibrating pipeline diagnosis system and method. Background technique [0003] Pipelines are used to transport many types of gases and liquids. Pipelines, whether buried or above ground, can transport such materials for hundreds or even thousands of kilometers. Oil pipelines and natural gas pipelines are just two examples of materials being transported via extensive networks of pipelines. [0004] Pipes are designed to last for many years. However, these pipes cannot last forever. If the transported material is at least partially corrosive, the pipe wall may gradually corrode over time. This can lead to weakening...
