光学双基站空间定位测量系统在主管道检测中的应用

Application of Optical Dual Station Space Measurement System in Main Pipeline Inspection

目前核工程建设领域高精密测量仪器装备主要依赖进口,随着国际环境复杂化,核工程领域部分企业在精密仪器及核心零部件采购方面已受到直接影响,在此背景下开展自主可控的测量装备国产化研发。为保障研发成果的现场适用性,在系统研发基础上以核电厂主管道检测为例开展现场应用,通过实施思路分析确定其操作要点,并通过现场实际应用总结出一套主管道检测工艺流程,同时与激光跟踪仪进行对比测试。通过对测量精度、测量范围、测量重复性精度等方面进行实践分析,表明该系统具有非接触式测量、数据即时反馈等特点,可以在近距离通过拍摄的方式,瞬时获取被测物的大量数据信息,其测量精度可达到0.14 mm,优于0.3 mm的安装测量要求,能够较好的满足现场使用需求,结果验证了该系统在核工程领域高精密测量仪器国产化替代方面具有一定的可行性。

The reliance on imported high-precision measurement instruments in nuclear engineering construction has been challenged by the evolving international environment,impacting procurement for some enterprises.Consequently,there is a drive towards the domestic development of autonomous and controllable measurement equipment.This study focuses on the application of such equipment in the main pipeline detection of nuclear power plants,using system research and development as a foundation for on-site implementation.The operational key points are identified through the analysis of implementation concepts,and a main pipeline detection process flow is established based on field application.Comparative testing with a laser tracker assesses measurement accuracy,range,and repeatability.The system,characterized by non-contact measurement and real-time data feedback,can rapidly acquire extensive data through close-range shooting.It achieves a measurement accuracy of 0.14mm,surpassing the 0.3mm installation measurement requirement,and thus,better satisfies on-site needs.The findings indicate the feasibility of this system as a domestic alternative to high-precision measurement instruments in the nuclear engineering sector.
