专用经纬仪快速检定系统设计

Design of Fast Verification System for Special Theodolite

为了提高经纬仪检定的效率和精度,设计了一种专用的经纬仪快速检定系统。文章介绍了其组成、工作原理和软件设计,着重介绍了独特的光学读数图像自动识别装置及各仪器与计算机的通讯,并对系统的测量不确定度进行了评定。实践证明,系统完全符合经纬仪检定的要求,大大降低了检定人员的劳动强度,为检定工作自动化程度的提高提供了一个有用的借鉴。

In order to improve efficiency and precision of verification for theodolite, a verification system for special theodolite is designed. The composing, operational principle and software design of the system are introduced, emphatically its special image auto-identification system for optical reading and communication between instruments are presented.Measuring uncertainty of the system is assessed. Practices have proved that the system meets the need completely, reduces worker's intensity of labor and provides a available reference for improvement of automation in verification.
