Problems solved by technology

[0003] The accuracy verification of the Beidou positioning antenna includes two parts, namely the accuracy of the antenna itself and the accuracy of the actual measurement. The verification of the equipment itself is mostly carried out by higher-precision equipment in quality inspection centers in various places, while the actual measurement accuracy is generally determined by the user. Self-verification, most users basically omit this step in order to avoid cumbersome procedures and reduce costs, which is also related to the lack of ready-to-use verification devices

Abstract

The invention provides an apparatus for examining the positioning precision of a Bipolar positioning antenna. The apparatus includes a horizontal X-axis guide rail and a vertical Z-axis guide rail which are vertically disposed, a positioning module which is arranged on the vertical Z-axis guide rail or the horizontal X-axis guide rail, a displacement simulator, a PLC control module and a data processing backend. The apparatus fixes a to-be-examined Bipolar positioning antenna to the positioning module and inputs a displacement mode which is set manually to the displacement simulator. The apparatus then controls a servo motor through the PLC control module to drive the positioning module to move. Based on the coordinate data transmitted by the Bipolar positioning antenna and the displacement simulator, the apparatus obtains one monitoring displacement curve and one actual displacement curve after data processing. The apparatus then examines the positioning precision of the Bipolar positioning antenna by comparing the monitoring displacement curve and the actual displacement curve. The apparatus can directly simulate geological displacement and is advantaged by simple structure, easy operation and high measuring precision.

Description

technical field [0001] The invention relates to the fields of geological disaster monitoring, geodetic surveying and engineering construction, in particular to a verification device and method for detecting the positioning accuracy of a Beidou positioning antenna. Background technique [0002] The process of monitoring geological disasters plays an important role in analyzing the mechanism of formation and forecasting and early warning. Due to the effect of natural disasters, strata and soil will undergo different degrees of subsidence and translation. The geological deformation of a fixed observation point can be known by the displacement (coordinate position change) before and after the occurrence of natural disasters. With the development of the Beidou satellite positioning system, it is possible to use the positioning function of the Beidou satellite (Beidou positioning antenna) to monitor geological deformation. Considering that the accuracy requirements of deformation...
