Detachable GPS/Beidou positioning and measuring device

Abstract

The invention discloses a detachable GPS / Beidou positioning and measuring device, which includes a base, a cylindrical part, a guide rail, a surveying and mapping trolley and a GPS or Beidou surveying instrument, and the cylindrical part includes a first cylindrical part and a second cylindrical part. A cylindrical piece, and the surface is provided with evenly distributed positioning holes, the first cylindrical piece is fixedly connected with the base, the second cylindrical piece is placed in the first cylindrical piece, and the fastener is passed through the positioning hole. The first cylindrical part and the second cylindrical part are fixed, the upper end of the second cylindrical part is provided with a fixed connector, the section of the guide rail is "convex" shape, and the side of the guide rail is provided with a groove perpendicular to the guide chute. the through hole, the fixed connector passes through the through hole and is locked by a nut; the first cylindrical member is hinged with a telescopic rod, and the free end of the telescopic rod is provided with a block; On the guide rail, the connecting chain is slidably connected with the guide rail, so the present invention is convenient for disassembly and assembly, and has increased practicability.

Description

Technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a dismountable GPS / Beidou positioning measurement device. Background technique [0002] With the development of geographic information system and digital city construction, the degree of automation of surveying and mapping technology has become higher and higher. The surveying and mapping method is mainly through manual surveying and mapping, specifically, surveying and mapping personnel use professional surveying and mapping instruments to conduct outdoor operations to obtain high-precision surveying and mapping data. In recent years, the rapid development of mobile surveying and mapping technology is an important direction for the future development of surveying and mapping technology. Its efficiency is greatly improved compared with manual surveying and mapping, and the surveying and mapping area is wider. However, the existing mobile surveying and mapping devices ar...

AI Technical Summary

Problems solved by technology

However, the existing mobile surveying and mapping devices are complex in structure, and the cost of manufacturing research and development is too expensive, which has a certain impact on their popularization and promotion; and some special geographical locations are difficult for surveying and mapping personnel to reach, which greatly increases the difficulty of surveying and mapping
