Control network measurement method

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...

Problems solved by technology

The linear control network has a narrow and long network shape and is not closed from the beginning to the end. Due to the cumulative transmission of measurement errors from one station to another, the linear control network is prone to distortion, so it is impossible to obtain high-precision linear control network coordinates and cannot guarantee the overall straightness requirements of the equipment.
