Problems solved by technology

Its shortcoming is that it is necessary to build magnetic marker points at multiple positions of the pipeline, but domestic pipelines have not considered this requirement during the construction process, so this technology cannot be used to detect and locate pipelines, especially submarine pipelines
On the other hand, if the pipeline is modified to build magnetic markers, the cost is high and it is difficult to implement

Abstract

The system comprises: a driver, a magnetic leakage probe, a magnetic leakage signal processing device, a power device, a milometer on the rolling wheel of processing device, a rotary encoder and a positioning analysis module both fixed in the processing device; wherein, using gimbals to connect the first four devices in turn. This invention realizes precise positioning, and overcomes accumulated error.

Description

technical field [0001] The invention relates to a system in the technical field of detection, in particular to a pipeline detection defect location system. Background technique [0002] Pipeline transportation is the main way of oil and natural gas transportation. At present, nearly 90% of crude oil and 100% of natural gas in my country are transported through pipelines. Once a pipeline accident occurs, it will not only cause huge economic losses, but also have serious consequences on society and the environment. The direct and indirect economic losses are huge, and the repair costs are also very high. Only by researching and developing an intelligent detection system device for oil and gas pipelines suitable for the actual situation of my country's pipelines, regularly testing and evaluating pipelines, and putting the safety status of pipelines in operation management can this problem be fundamentally solved. The defect location system of the pipeline detector is a key co...
