The R&D Of Submarine Pipeline Axis Trajectory Detector

This paper is relying at the project of Tianjin Dagang Oilfield Construction Co., Ltd for submarine pipeline axis trajectory, developed for monitoring the three-dimensional of sub sea pipeline when pipe-laying vessel carried pipelining work. With the development and utilization of offshore fields in succession, the axis track detector in submarine laying has caused more and more widespread concern in society. However, the technology about the submarine pipeline axis trajectory detector in China is still immature. To this end we have designed and developed a set of submarine pipeline axis trace detection devices.Axis track detecting means is a cross-cutting and interdisciplinary topics related to the content machine multiple disciplines. This paper is submarine pipeline axis trace detection devices based on the gyroscope multidimensional detection technology and the PIC microcontroller. This device adopts three-dimensional attitude sensors for collecting 3D pose information. 3D pose sensor uses a SCM as the microcontroller and the angle and gyroscope chip is responsible for the inclination information and three-dimensional attitude information of pipeline. We adopt Delphi7.0 for the development and design of monitoring interface of submarine pipeline axis trace detection devices, combined with SQL 2000 to store and to deal with the data. We deal with the data from 3D pose sensor in the host computer system, and adopt the collected data for eliminating errors, and calculate the gyroscope in the way of quaternion algorithms.This paper analyzes the current status of the development and application in China and abroad in the 3D pose pipelining pipeline information monitoring technology. Self-designed the mechanical structure and drive mechanism of detection device, and achieve the real-time collection and display of information pipeline when the pipe-laying work. In this paper, we design the hardware circuit first, for example the serial communication module, A / D converter module and clock module. We design the 3D pose sensor to collect the pipeline information, and analyze the error of angle sensor and gyroscope, and complete the work on the error compensation. Upper monitoring system is designed to process and display the collected information, so that the worker can adjust the plumbing work. we do the experiments on the Tianjin Dagang oilfield experiment platform, and verify the feasibility of this device in engineering.
