Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to an ultra-deep pipeline detection system with calculation and analysis functions. Background technique [0002] With the development of urban construction and the improvement of construction technology, the construction of underground pipelines has also been rapidly developed, and the buried depth of pipelines is getting larger and larger. However, the effective detection depth of various pipeline detection instruments commonly used at present is mostly 5 meters. However, the greater the buried depth of the pipeline, the greater the detection error value, which brings severe challenges to construction design and pipeline maintenance.

AI Technical Summary

Problems solved by technology

[0003] Existing signal transmitters such as Radiodetection RD8100 pipeline detector, Weimai V2 pipeline detector and other signal transmitters have very low output power when they encounter high ground resistance or other environmental factors, which directly makes the receiver The signal received by the machine is very low, or even no signal at a long distance

The signal transmitter is bulky, heavy, and inconvenient to carry

All kinds of interface cables of the signal transmitter are non-standard customized interfaces. Once damaged, returning to the factory for repair is time-consuming and laborious

[0004] Most of the existing signal receivers are horizontal detection methods, which cannot accurately measure the depth of the target pipeline
