Description

Technical Field

[0001] The utility model relates to the technical field of topographic surveying and mapping, in particular to a topographic surveying and mapping device for water conservancy projects. Background Art

[0002] Topographic surveying refers to the work of surveying and mapping topographic maps. That is, the projection position and elevation of the objects and terrain on the earth's surface on the horizontal plane are measured, and they are reduced at a certain ratio and drawn into topographic maps with symbols and annotations. Topographic surveying mainly uses aerial photogrammetry, including control measurement and fragmentary measurement. According to the different instruments used, fragmentary measurement is mainly divided into planar instrument mapping method, small planar instrument and theodolite joint mapping method, theodolite mapping method, etc. Among them, RTK (Real-time kinematic) is a carrier phase difference technology, which is a differential method for real-time processing of carrier phase observations of two measuring stations. The carrier phase collected by the base station is sent to the user receiver to calculate the difference coordinates. This is a new and commonly used satellite positioning measurement method. Previous static, fast static and dynamic measurements all needed to be solved afterwards to obtain centimeter-level accuracy. RTK is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. It uses the carrier phase dynamic real-time differential method and is a major milestone in the application of GPS. Its appearance has brought new measurement principles and methods to engineering layout, topographic mapping and various control measurements, greatly improving work efficiency.

[0003] During the use of RTK receivers, the survey area is often in a steep, rugged, narrow space, long-distance transportation, house area, forest, repeated operation and other working environments. The RTK receiver is often blocked by houses or forests, resulting in satellite signal interference and cannot operate normally, or the measurement target is too high (too far) to make data collection difficult, etc., and the height of the RTK centering pole needs to be repeatedly adjusted. The existing RTK measurement device mobile station generally includes a centering pole and an RTK receiver body installed on the centering pole. The centering pole usually includes a support pole and a sleeve. When setting the RTK measurement device, it is necessary to adjust the height of the RTK receiver body, and then it is necessary to pull the sleeve out of the support pole for a certain length, and then use the locking clamp set on the support pole to limit and clamp the sleeve. However, due to the convenience of carrying, the length of the support pole is limited, which leads to a limited height range of the RTK receiver body. Therefore, in view of the above phenomenon, a topographic surveying and mapping device for water conservancy projects is proposed to meet the needs of actual use. Utility Model Content
