步进光电式变形监测仪器的长期应用

为了解步进光电式变形监测仪器的长期应用情况,根据17年的长期应用,分析典型倒垂线测点的166组观测数据,结果显示自动化与人工比测的规律一致,两者差值符合正态分布规律,基准长度测值的离散性较小,没有趋势性变化,其他测点也有相似的规律。在工程运行单位的有效管理之下,步进光电式变形监测仪器及其自动化系统在水工环境下保持高精度长期正常运行,满足大坝安全监测的需要。

Long-term application of stepping photoelectric deformation monitoring instrument

Inorder to acquire the status of the long term application of the stepping photoelectric deformation monitoring instrument,166 sets of observation data from the typical inverted pendulum measuring points are analyzed according to the long-term application of 17 years. The result show that the changing laws of both the automatic monitoring and the artificial observation are consistent,while the difference distribution between the automatic monitoring and the artificial observation accords with that of the normal distribution law with less discreteness of the observed value of the datum length and without trending change. Under the effective management of the project operating department,the instrument and the automatic system keep a high accuracy and long-term normal operation under the hydraulic environment,thus meet the need of the dam safety monitoring.
