摘要

管道运输是现代石油、天然气等能源运输的主要方式之一。管道内检测器跟踪定位技术可实现对管道内检测器的运行状态和位置的实时监测,是管道无损检测工程应用的必要条件。本文在现有定位技术的基础上,重点优化设计了里程轮定位系统。通过三个里程轮获取定位数据,并对这些冗余的里程信息进行数据融合处理,实现了对管道内检测器的精确定位。同时,三里程轮计数能够校正弯道、坑洼处里程计数值。
        Pipeline transportation is one of the main modes of energy transportation of modern petroleum and natural gas. The tracking and positioning technology of in-pipeline detector can realize the real-time monitoring of in-pipeline detector's running state and real-time position, which is a necessary condition for the application of non-destructive testing in pipeline engineering. Based on the existing positioning technology, this paper focuses on optimizing the design of the range wheel positioning system. Positioning data was obtained through three mileage wheels, and the redundant mileage information was processed by data fusion, so as to achieve the accurate positioning of detector in the pipeline. Three mileage wheel count is adopted to calibrate the mileage meter values at curves and pits.
