全測站經緯儀校正週期研析

內政部國土測繪中心為落實儀器校正制度，97年成立測量儀器校正實驗室辦理測量儀器校正作業，於99年通過認證，101年4月1 日起對外提供校正服務。為對儀器校正領域有更深入的探討，並針對全站儀由各層面考量以客觀之方法評估校正週期，本研究輔以問卷方式調查全國相關測繪、地政及工程等單位對於評估校正週期看法，藉由各方回饋意見進行分析，最後提出結論與建議供後續相關研究參考。本研究顯示校正週期隨著使用年限、地形環境及人為等不可控制因素越多，校正週期亦應隨之縮短。80%以上受訪者贊成訂定最佳校正週期，並認同儀器已使用年數、保存環境與校正週期相關。各面向經統計結果之贊成度皆相當高，顯示本研究所採用之各面向具顯著意義。每部儀器仍應就本身業務「狀況」、儀器使用情形評估合適校正週期。儀器作業於山區或高精度需求，校正週期建議1年1 次。儀器送修次數每累積2 次，或月使用天數在12 天以上，校正週期建議1 至2年1 次。 The Surveying Instrument Calibration Laboratory(SICL) of National Land Surveying andMapping Center(NLSC) was founded in 2008. A quality management systems of calibration werethen developed to meet the requirements of international certification standard ISO/IEC 17025. Thislaboratory has passed the recognition by Taiwan Accreditation Foundation(TAF) in 2010. TheLaboratory has been providing external calibration services since April 1, 2012.To research the calibration cycle of total station, different-oriented evaluation and questionnairesurvey are introduced. The questionnaires designed to universities, private companies, governmentorganizations, association in the field of survey, construction and land are analyzed objectively.According to the result in this paper, there are several conclusions: 1.The respondents strongly approve of setting calibration cycle and highly trust outputs fromsurveying instruments calibration cycle. 2.Owing to surveying instruments usage and preservation affected by natural and human factors, revising calibration cycle by different situations is necessary.3.The more uncontrollable factors exist, the shorter calibration cycle is.4.The results of adjusting calibration cycle to different environment and situation research shows thatuncontrollable factors increasing shortens the calibration cycle.5.Setting a suitable calibration cycle should consider uncontrollable factors, performances andcharacteristics of equipments.6.Based on demand of high precision or tasks implementing in mountain area, calibration cyclerecommended is once a year.
