Embodiment 1

[0035] Such as figure 2 Shown is the existing three-dimensional precision control network to be measured in this embodiment, which is used as a benchmark for installation, adjustment and monitoring of equipment, wherein m control points P are set 1 …P m , the control points are equidistantly distributed on two parallel straight lines, that is, the control points on the two straight lines are evenly arranged and three-dimensionally distributed along the ground and wall of the site where the equipment to be installed is located, so as to surround the entire equipment to be installed. It can be seen that the entire linear site from the front end to the end of the equipment to be installed is divided into several sections according to the section, and each section has 2 control points distributed on the ground. make figure 2 The extension direction of the middle control network is the vertical direction, and the direction perpendicular to the extension direction of the control...

Abstract

The invention provides a control network measurement method, which comprises the steps of: additionally arranging n datum points in an existing control network, wherein the datum points are arranged in a straight line; presetting a datum line for a control network to be measured; measuring offset distances between the n datum points and the datum line on the horizontal plane respectively; placingmeasurement targets at m control points of the control network and n datum points of the datum line; erecting measurement equipment at q preset stations, and utilizing the measurement equipment to measure and obtain a control point observation value and a datum point observation value in a preset observation range of each preset station; and solving coordinates of the m control points by adoptingan adjustment solving algorithm. According to the control network measurement method, the datum line is introduced to restrain the control network, the coordinates of all the control points in the control network are solved by adopting the adjustment solving algorithm, and the control network measurement method has high absolute point location precision.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a method for measuring a control network. Background technique [0002] In the installation and positioning of equipment such as particle linear accelerators and high-speed rail guide rails, since these equipment are arranged in a straight line, it is required to align all equipment on a straight line within a range of hundreds of meters or even kilometers. In order to provide a positioning reference for equipment installation, adjustment, and monitoring, it is necessary to lay out a precision collimation control network in the space. The control network is composed of several control points, which are generally evenly distributed on the wall and the ground. Before installing the equipment, it is first necessary to measure the collimation control network, so as to establish a high-precision installation and positioning reference. Therefore, the measurement accuracy of the col...
