TJ9000陀螺全站仪在井下导线测量中的应用

Application of TJ9000 Gyro Total Station to Underground Traverse Survey

为了减小测角误差引起的导线点位误差,提高井下导线控制网精度,运用TJ9000陀螺全站仪在井上、井下进行陀螺定位和平差处理,实现井下导线的精确定向。文中介绍了陀螺全站仪的工作原理和仪器常数测定,并利用EXCEL编写了陀螺数据的处理过程,通过实例分析,TJ9000陀螺全站仪的使用极大提高了井下导线的精度和可靠性。

In order to reduce the error of the traverse point caused by the angle measuring,increase the accuracy of the underground traverse control network,TJ9000 gyro total station was used for gyro orientation and the adjustment treatment in surface and underground realizing the accurate orientation of the underground traverse.The working principle of the gyro total station and the instrument constants measurement were introduced and the gyro data processing was composed by the EXCEL.TJ9000 gyro total station greatly improved the accuracy and reliability of the underground traverse by analyzing the case.
