陀螺全站仪是将陀螺仪和全站仪结合成一体的仪器。根据陀螺的特性,形成的测定真北方向的测量系统。由于陀螺仪的寻北原理,使得其不受时间和环境等条件的限制,另外其观测简单、精度较高,并且能够全天候观测,本文讨论了陀螺全站仪是否可以适应井下复杂多变的温度、湿度等条件,精度能否达到使用要求。另外,在应用定向边一次定向标准偏差时,分别从实验和实际作业的角度对该仪器定向方法的选择进行了讨论。最后,本文分别从上两种表示方法对陀螺全站仪的定向精度进行评定。
Gyro total station is a combination of gyroscope and total station instrument. According to the characteristics of the gyroscope, a measurement system for determining the true north direction is formed. Due to the north-seeking principle of the gyroscope, it is not limited by the time, environment and other conditions. In addition, the observation is simple, the precision is high, and the observation can be conducted around the clock. This article discusses whether the gyroscope can adapt to the complicated underground temperature , Humidity and other conditions, accuracy can meet the requirements. In addition, when orienting the standard deviation once using the orienting edge, the selection of the orienting method of the instrument is discussed separately from the perspective of experiment and practical operation. Finally, this paper evaluates the orientation accuracy of the gyro total station respectively from the above two representations.
