Oil and gas pipeline displacement monitoring system in mining subsidence area

Abstract

The invention discloses an oil and gas pipeline displacement monitoring system in a mining subsidence area. A data acquisition and transmission system comprises a pipe body strain monitoring device, a pipe body relative displacement monitoring device, a mining subsidence area horizontal deformation monitoring device, a preliminary data processing device and an energy supply and positioning device, wherein the preliminary data processing device comprises a lower computer, a fiber bragg grating demodulator, an optical switch and an optical fiber junction box; the lower computer is connected with the first wireless communication module and the fiber bragg grating demodulator, the fiber bragg grating demodulator is connected with the fiber junction box through the optical switch; the energy supply and positioning device comprises a solar cell panel and a positioning device; the solar cell panel is installed at an upper end of a supporting frame and connected with a storage battery through a charging template; a data receiving and processing system comprises a fault energy management system, a safety positioning management system, a data analysis, processing and display system, a communication unit and an intelligent mobile terminal; the communication unit comprises a second wireless communication module and a communication host. The system can effectively solve a problem of power supply and facilitates fault location.

Description

technical field [0001] The invention belongs to the technical field of displacement monitoring of oil and gas pipelines, and in particular relates to a displacement monitoring system of oil and gas pipelines in goaf subsidence areas. Background technique [0002] In the face of numerous goaf subsidence disasters, although pipeline operating companies have taken active engineering protection measures, there are some drawbacks in these current measures. Firstly, the cost of these measures is relatively high, and secondly, the protective engineering of the existing measures cannot achieve the goal of "once and for all", not only because there are many uncertain factors in the design and construction process, but also because the period of protection and treatment is long and the timing of treatment is too long. Not easy to grasp. Displacement monitoring of oil and gas pipelines is a main way to prevent and control goaf subsidence disasters, and it is also an efficient and low-...

AI Technical Summary

Problems solved by technology

[0006] The oil and gas pipeline monitoring system used in the goaf subsidence area in the prior art has the following problems. The power supply problem is not easy to solve, especially when it is installed in a relatively remote location. At the same time, it is not convenient for troubleshooting and maintenance, and the monitoring system cannot be guaranteed Long-term, effective and stable operation
