Description

Technical Field

[0001] The utility model belongs to the field of measurement technology, in particular to a prism auxiliary lighting return light device for a total station. Background Art

[0002] Total stations can be used in almost all surveying fields, and are not only used in surveying and mapping projects, construction projects, transportation and water conservancy projects, cadastral and real estate surveying, but also in the installation and commissioning of large-scale industrial production equipment and components, hull design and construction, deformation observation of bridges and dams, geological disaster monitoring, and sports competitions.

[0003] However, when performing total station measurement in some dark or no light scenes such as basements, the total station needs to first aim at the bottom of the prism pole and then slowly aim upwards, so as to reduce the error in the observed data and improve the accuracy of the data. However, the prism is prone to slow reading or failure to read in dark scenes. At this time, an assistant is required to light up the light to assist the total station in reading the prism. However, the above-mentioned light-filling method requires the cooperation of other personnel, which is inconvenient to operate. Therefore, the above-mentioned defects are studied and improved, and a total station prism auxiliary lighting return light device is provided. Utility Model Content
