Embodiment Construction

[0031] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] see now figure 1 , figure 1 is a schematic block diagram of a trenchless guidance system 100 according to an embodiment of the present invention.

[0033] The trenchless guidance system 100 includes a detection probe 1 having a receiver of a three-dimensional antenna (for example, the three-dimensional antenna is a three-dimensional orthogonal loop antenna) for receiving three-dimensional information. The trenchless guidance system 100 also includes a first processor 2 (such as a central processing unit CPU), and the first processor 2 receives the output signal of the detection probe 1; the first processor 2 may specifically include an analog-to-digital conversion The device (A / D) 21 is used to convert the received signal from analog to digital. The trenchless guidance system 100 also includes a second processor 3 (for example, it can also be a central pro...

Abstract

The invention provides a guiding system and a guiding method for non-excavating. The non-excavating guiding system comprises a detection probe (1) for acquiring information, a first processor (2) for pre-processing the information acquired by the detection probe, a second processor (3) for performing frequency domain processing on the information processed by the first processor, and a synchronous display (4) for displaying the information processed by the second processor. The second processor (3) comprises a spectrum analyzer (31); and the spectrum analyzer (31) is used for analyzing one or more predetermined signal frequency ranges, and processing the analyzed information to select one frequency or one frequency range of which the signal-to-noise ratio of signals is relatively larger.

Description

technical field [0001] The present invention relates to a guiding system and a guiding method, in particular to a guiding system and a guiding method for trenchless technology. In particular, the trenchless guiding system and the trenchless guiding method provided by the present invention can resist noise interference. Background technique [0002] Trenchless technology refers to the use of geotechnical guidance, directional drilling and other means to carry out construction such as laying, replacing or repairing various underground pipelines without digging trenches on the surface. This technology has significant social and economic benefits, especially for laying pipelines in areas where excavation operations cannot be implemented, such as crossing roads, railways, buildings, rivers, historic sites, downtown areas, crop and vegetation protection areas, etc. The technology is now widely used in engineering sectors such as gas, telecommunications and power.
