Research on Tiny Leak System for Oil Transmission Pipelines

Generally speaking, the traditional tiny leak detection methods are limited in their ability to survey long reaches of the oil transmission pipelines effectively, highly cost and pose serious risks in blocking the pipeline, etc. So an improved detection system based on ARM-Linux and MEMS sensor is proposed. The spherical detector, whose diameter is less than the pipe diameter, takes advantage of the new system. The principles of the system, hardware components, software design and the experimental results are introduced in details. Some simulation experiments about leakage in water transmission pipelines are carried out. The experiment results show that the device can run safely, operate conveniently, identify and locate the leakage point accurately. It provides technical support for the tiny leak detection of oil transmission pipeline with high precision and low cost.
