摘　　要：为了提高验潮仪检定装置的技术指标,本文提出了一种基于超高精度激光追踪原理的潮位计量检测装置。新装置指标可提高至U=0.86 mm,k=2,极大地满足《测量仪器特性评定》JJF1094-2002对计量标准装置的技术指标要求。通过0~8 000 mm水位范围试验结果表明,两种原理的检测装置测得数据差值绝对值的曲线基本一致;在8 000 mm水位点出现最大值,分别为1.292 mm和1.883 mm,主要原因是当前装置该水位点数据读取受外界强光线的影响;新检测装置不仅精度更高,而且不会受外界环境影响,能够更好地满足高精度潮位仪的检测需求。本文对提升验潮仪计量检测技术和确保海洋潮位数据的准确可靠,进而对完善我国海洋预报、海洋综合管理等方面具有重要的理论和现实意义。In order to improve the technical index of tidal calibrating device, a calibrating device based on ultrahigh precision laser tracking principle is put forward in a creative manner. The technical index of the new device can be improved to U=0.86 mm, k=2, which can meet Performance evaluation of measuring instrument(JJF1094-2002) for the measurement standard device. The results of test result of 0-8000 show that the absolute value curves of the differences measured by the two devices are the same basically, and the maximum values are 1.292 mm and 1.883 mm at 8000 mm, respectively. The main reason is that reading data are affected greatly by the external strongest light at 8000 mm in the current device. The new device not only has higher accuracy but also will not be affected by the external environment, can be better to meet the requirements of the high-precision tide gauge. The paper has great importance for improving the measurement and detection technology of the tidal gauge and ensuring accurate and reliable tide data, and also for improving our country marine forecasting and integrated ocean management and so on which has great theoretical and practical significance.
