Abstract:
In this study, a high-precision small-range static level is designed, and the mechanical structure and measurement principle of the static level are expounded in detail. In this paper, the system accuracy of the static level in settlement monitoring application is analyzed, and the maximum residual error of the instrument is determined according to the system accuracy design requirements. In order to ensure the measurement accuracy of the instrument, the key components of the instrument are selected. The test verifies that the static level has the characteristics of high measurement accuracy, good repeatability, small hysteresis error, low resolution and strong environmental adaptability, which meets the design requirements. The static level was applied to the settlement monitoring of a Large-scale Scientific Facilities. Through the analysis of field lifting experiment and application data, it was shown that the static leveling system works well, and the measurement accuracy of the system meets the design accuracy. The real-time and accurate monitoring of the settlement change of the Large-scale Scientific Facilities is realized, which provides strong guarantee for the stable operation of the device.
