Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline detection equipment, in particular to a small-diameter underground pipeline tracking and mapping device. Background Art
[0002] Underground pipeline tracking and mapping is a technology and method designed to accurately determine and record the location, depth, type and status of underground pipelines and facilities. With the development of technology, ground penetrating radar has been widely used in underground pipeline tracking and mapping. Ground penetrating radar is a device used for underground exploration and detection. It determines the location, shape and properties of underground structures and objects by emitting electromagnetic waves and receiving reflected signals. The working principle of ground penetrating radar is based on the reflection and refraction of electromagnetic waves when they propagate in different media. When the radar transmitter sends electromagnetic waves, these waves pass through the surface of the earth and are reflected or penetrated according to the properties of underground objects and structures. After the receiver receives the reflected signal, it can generate an image or profile of the underground structure by analyzing the characteristics of the signal such as time delay, intensity and frequency.
[0003] In actual use, ground penetrating radar is often installed at the bottom of a cart, which is pushed on the ground by staff to continuously scan and detect underground pipelines. Since the ground penetrating radar may encounter various road undulations or foreign objects when moving on the ground, it is very easy to cause bumps and damage to the ground penetrating radar. At the same time, the vibration of the cart when rolling over these uneven roads will cause a small range offset of the receiver, resulting in slight deviations in the collected data. For some larger diameter pipelines, these deviations have little effect on the accuracy of the data, but when it is necessary to survey and map small diameter pipelines, slight deviations will also have a greater impact on the surveying and mapping data, ultimately resulting in insufficient accuracy of the surveying and mapping results.
