Underground water pipe culvert endoscopic positioning system and working method thereof

Abstract

An underground water pipe culvert endoscopic positioning system comprises a mechanical ship, an image acquisition module, a data processing module, a space positioning module, a wireless module, a client APP and a router, an image acquisition module, a data processing module, a space positioning module and a wireless module are mounted on the mechanical ship; a network port of the data processing module is connected with a router, and the router is in wireless communication with a client APP; an acquisition end of the image acquisition module is connected with a first communication port of the data processing module; and the data processing module sends the spatial data to the client APP. The underground water pipe culvert endoscopic positioning system can detect the trend of an underground water pipe culvert or an underground river in real time, can display the internal structure of a detected object at high definition in real time, and provides technical support for subsequent planning, construction and other work. Particularly, theunderground water pipe culvert endoscopic positioning system has very high application value in the aspects of desilting, damage repair and the like of sewage pipe culverts.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to an endoscopic positioning system for underground water pipe culverts. Background technique [0002] Underground pipes and culverts are hidden projects, and scientifically finding out the exact location of underground pipes and culverts is an important technical issue in modern urban management. In my country, the initial research on underground pipe and culvert detection technology mainly focused on the detection of underground pipes and culverts using geophysical methods. In the 1990s, there was an upsurge of applications. Even so, there is still a big gap between us and the world's advanced level. The pipeline inspection work is still in its infancy. The number of pipelines that have been inspected is less than 1 / 10 of the total pipeline, and no pipeline has been re-inspected. Due to various reasons, pipeline operators and managers have insufficient understanding of the impor...

AI Technical Summary

Problems solved by technology

Second, the detection depth of geomagnetic induction method, electromagnetic wave method, seismic wave method, acoustic wave method and high-density electrical method is greatly limited according to their principles.

Third, various methods mainly use the difference in physical properties between the pipe culvert and its surrounding medium, which is easily affected by external interference signals, resulting in low detection accuracy

Fourth, the degree of automation is not high, and the data recording method is relatively primitive, which requires experienced technical personnel to identify, and the subjectivity component has a greater influence

Fifth, there are many structures in the urban area and the site is very narrow, which does not have the working conditions for high-density resistivity method, seismic wave method and other methods

In short, in the detection of urban underground pipes and culverts, it is often difficult to obtain reliable data such as location and buried depth with existing technologies, leaving hidden dangers for future urban pipes and culverts management.
