全站仪性能评估与预警系统的设计与实现:一种模糊综合评价方法的应用

    Design and Implementation of Total Station Performance Evaluation and Early Warning System: Application of a Fuzzy Comprehensive Evaluation Method

    • 摘要: 计量机构在对计量器具进行周期检定过程中会产生大量的检定数据,这些数据蕴藏的巨大的经济社会价值尚未得到充分开发利用。目前,计量器具性能评价还停留在对于单台仪器质量或计量性能的评价阶段。以全站仪检定产生的海量数据为研究对象,提出了一种较为通用的计量器具性能评价及失效预警的方法。首先对全站仪检定数据进行数据分析处理,其次利用TOPSIS法对单台全站仪的性能进行综合评价,然后利用Vague集决策理论对各生产厂家的全站仪质量进行总体评价,再根据最大允许误差和斜率法对全站仪的有效性进行预警分析,最后基于此方法搭建计量器具性能评价及失效预警系统。通过对实际全站仪检定数据展开实验,开发出来的计量器具性能评价及失效预警系统有效实现了全站仪的性能评价及失效预警。

       

      Abstract: Measuring institutions generate substantial verification data during periodic inspections of measuring instruments, but the immense economic and social value hidden within this data remains largely untapped. Currently, the evaluation of measuring instrument performance is limited to assessing the quality or metrological performance of individual instruments. This study proposes a generalizable method for evaluating the performance and predicting the failure of measuring instruments, using the vast amount of data generated from total station verifications. The process begins with analyzing and processing the verification data of total stations. Subsequently, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method is employed to comprehensively evaluate the performance of individual total stations. The Vague set decision theory is then utilized to assess the overall quality of total stations from various manufacturers. Early warning analysis of the total stations' validity is conducted using the maximum permissible error and slope methods. Finally, based on this methodology, a system for measuring instrument performance evaluation and failure early warning is constructed. Through experiments on actual total station verification data, the developed system effectively achieves performance evaluation and failure prediction for total stations.
