Non-excavation high-precision underground pipe network track detector

Abstract

The invention discloses a non-excavation high-precision underground pipe network track detector. A signal acquisition module (1) comprises a gyroscope (21), an acceleration sensor (22) and an encoder.The signal acquisition module is connected to a signal processing module (2), and the signal processing module is a signal conditioning circuit. The signal processing module is connected to a microprocessor through an AD sampling circuit (3) of a single chip microcomputer (4). The single chip microcomputer includes a microprocessor, an AD sampling circuit, a storage circuit (6) and an external device connection interface. The external device connection interface of the single chip microcomputer is connected with an upper computer (9) through an RS232 communication circuit (7) and a cable (8);and the output end of a power module (5) is connected to the signal acquisition module and the single chip microcomputer to supply power thereto. The signal acquisition module, the signal processingmodule, the single chip microcomputer, the communication circuit and the power module are mounted in a casing. According to the detector, three-dimensional measurement of an underground pipeline trackcan be achieved, the instrument measurement precision is high, a system is stable, and the cost is low.

Description

technical field [0001] The invention relates to an underground pipeline trajectory detector, in particular to a trenchless high-precision underground pipeline network trajectory detector. Background technique [0002] Trenchless pipe laying technology is widely used in the construction of various pipelines such as power cables, communication optical cables, gas, water supply and drainage pipelines, and petroleum, and is gradually replacing the traditional underground pipeline construction method of digging trenches and burying pipes. Due to factors such as construction level and technology, the trajectory of the completed pipeline is often different from the design trajectory of the pilot hole, and it is very important to accurately grasp the underground space position of the completed pipeline. The trajectory design of pipelines provides a basis to avoid pipeline intersections. At present, the methods used at home and abroad to measure the trajectory of completed pipelines...
