摘要
为解决架空线路勘察效率低和勘察数据分析存在偏差等问题,对线路勘察方案重新设计。利用可编程片上的系统云勘察技术实现架空线路的云分析和编程检测,对线路的维护调试和跟踪勘察提供数据支持。采用智能预排位跟踪技术实现了线路勘察的跟踪拍摄,建立的移动勘察仪能够根据不同的线路状况进行调整。利用截尾型序贯检验算法实现勘察数据的分析检测,通过判决条件和线路容量完成异常节点的推算。最后在载流量为75 A的线路中进行了试验。结果表明,所设计勘察架构试验线路载流量为75 A,勘察效率稳定在17.8条/h,异常线路分析结果偏差为0.68%。
In order to solve the problems of low efficiency of overhead line survey and deviation in survey data analysis,the line survey plan was redesigned.Use the system on programmable chip cloud survey technology to realize the cloud analysis and programming detection of overhead lines,and provide data support for line maintenance,commissioning and tracking survey.The intelligent preranking tracking technology was adopted to realize the tracking shooting of line survey,and the established mobile survey instrument can be adjusted according to different line conditions.The censoring sequential teset algorithm was used to realize the analysis and detection of survey data,and the calculation of abnormal nodes was completed through the judgment conditions and line capacity.Finally,the experiment was carried out in a circuit with a current carrying capacity of 75 A.The results show that the current carrying capacity of the experimental line of the design survey structure is 75 A,the survey efficiency is stable at 17.8 lines/h,and the deviation of the abnormal line analysis result is 0.68%.
