Device for performing measuring, positioning and coordinate transformation under complex terrain condition and construction method of device

Abstract

The invention relates to a device for performing measuring, positioning and coordinate transformation under a complex terrain condition and a construction method of the device. The device comprises anelectronic tachometer, a prism, a fixing frame and a positioning frame, wherein a positioning rod and a regulating mechanism which can regulate the angle of the positioning rod are arranged on the positioning frame; a limiting mechanism is arranged on the fixing frame, and can move downwards to be connected with the upper end of the positioning rod, so that a fixing disk is mutually perpendicularto the positioning rod; the limiting mechanism moves upwards to limit the electronic tachometer arranged on the fixing disk, so that the electronic tachometer and the positioning rod are centered vertically. After the prism is positioned by the electronic tachometer, the prism is disassembled from the positioning rod, and then the electronic tachometer and the fixing frame are transferred above the positioning frame; the positioning rod mutually cooperates with the limiting mechanism, so that the step of coarse regulation of the fixing frame is omitted; then after the electronic tachometer isleveled, the electronic tachometer and the positioning rod are centered vertically by the limiting mechanism, so that a laser positioner can be accurately aligned with the coordinate determined by the prism, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of engineering surveying, in particular to a coordinate conversion device for surveying and positioning under complex terrain conditions and a construction method thereof. Background technique [0002] In engineering construction, it is necessary to carry out surveying and mapping at various locations, and in the process of surveying and mapping, due to the use of different coordinate systems, it is necessary to perform coordinate conversion between different coordinate systems. The existing surveying and mapping tools are generally total stations. Transformation requires the use of prisms. [0003] In the process of surveying and mapping, first establish the coordinate system through the total station, then place the prism at the coordinate position that needs to be converted, and use the total station to locate the position of the prism, and then transfer the total station to the position of the prism, so ...

AI Technical Summary

Problems solved by technology

However, the operation of accurately transferring the total station to the position of the prism is relatively troublesome. The existing operation steps are to mark the ground below the prism, and then use the laser locator at the bottom of the total station to locate according to the mark, but After positioning, the total station needs to be leveled, and after leveling, the laser may be offset, resulting in inaccurate positioning, and it is necessary to make small adjustments to the position of the fixing frame to align the laser with the mark. complicated operation
