Monitoring the corrosion of pipelines by evaluting the noise in data signals transmitted via the pipeline |
摘要 |
When a pipeline is used as a medium for data transmission using a VLP or ELF Electro-magnetic signal the presence of corrosion effects on the pipeline lead to noise signals appearing in the received data signal. The present invention relates to a method of separating out this noise signal and analyzing it to determine the corrosion status of the pipeline. Both the type and location of the corrosion effect can be determined in this way.
