摘要
目的通过三轴补偿全站仪与双轴补偿全站仪的测角精度的实测实验,探讨全站仪的三轴自动补偿的性能和适用情况.方法选用日本PENTAX公司的ATS-102型三轴补偿全站仪与双轴补偿全站仪,在有振动的实验区进行角度测量实验,采用全圆观测法进行测量,观测值经Chenvenet准则剔除粗差后,采用巴特莱法检验其测角精度.结果在视线倾角小于3°的情况下,所有各型仪器均可用半测回代替一个测回;但在视线倾角大于3°的情况下,三轴补偿系统全站仪仍可用半测回代替一个测回,且三轴补偿系统的全站仪观测值的稳定性也较好.结论ATS-102三轴补偿全站仪(即使在倾角超过3°的方向上)能实现包括视准轴在内的三轴自动补偿.三轴补偿系统全站仪存在的问题是抗恶劣气象条件较差,如在震源附近,风大等条件下,水平角发生变化,因此三轴补偿系统全站仪适合在精度要求较高的环境中使用.
To discuss the capability and applicability of tri-axis auto-correction system for Total Station, empirical test of accuracy of angle observation for dual-axis correction Total Station and tri-axis correction Total Station is implemented. The test uses ATS-102 model pan） and other five kinds of Total Station that include which includes tri-axis correction system（ made in Jadual-axis correction system. Angle observation test is carried out by way of direction observation in rounds under vibration circumstance. When mistakes in observation are removed following Chenvenet Rule, the Bartlett Test is introduced to check their difference of accuracy of angle observation. Under the circumstance of sight obliquity 〈 3°, half observation set can replace one set for all kinds of Total Station, but when sight obliquity 〉 3°, half observation set can replace one set only for Total Station which includes tri-axis correction system. Furthermore, the stability of observation of tri-axis correction Total Station is better than that of others. Total Station ATS-102 that includes tri-axis correction system can carry out three axis auto correction including sight axis correction even if in the direction of obliquity 〉 3~, but the issue for the tri-axis correction Total Station is poor against bad weather condition, such as near the epicenter, windy weather etc. , and horizontal angle observation isn t stable. So the tri-axis correction Total Station is applicable to high level accuracy measurement and in common condition.
