Bridge measuring point positioning method, control device, system and medium

Abstract

The invention relates to a bridge measuring point positioning method, a control device, a system and a medium. The method comprises the following steps: acquiring the total width of a beam bottom and the numbers of a plurality of laser probes needing to be called; respectively acquiring the vertical distance between the laser probe and the bottom surface of the bridge and the distance between the laser probe and the bottom edge of the to-be-measured bridge section; based on the total width of the beam bottom and the number of the laser probes needing to be called, measuring point spacing is obtained; based on the measuring point distance, the number of the laser probes needing to be called and the serial number of the current laser probe, obtaining coordinates of pre-projected laser of the current laser probe; and generating an angle adjustment instruction based on the vertical distance between the laser probe and the bottom surface of the bridge, the distance between the laser probe and the bottom edge of the to-be-measured bridge section, and the coordinate of a preset projection laser point of the current laser probe, and sending the angle adjustment instruction to each laser probe to enable the laser probe to project the laser point on the bottom edge of the to-be-measured bridge section. The method has the advantages that the measuring points are accurately arranged, and the accuracy of the bridge static load test is improved.

Description

technical field [0001] The present application relates to the field of bridge detection, in particular to a method for positioning bridge measuring points, a control device, a system and a medium. Background technique [0002] The bridge static load test is a verification method for directly testing the working state of the bridge structure. The static load refers to the vehicle load of the specified load level driving on the bridge at a slow speed. The strain and deflection measuring points are arranged on the bridge section, and the bearing capacity of the bridge is comprehensively analyzed according to the obtained data. [0003] When installing the measuring points, the staff determines the detection plan according to the width of the bridge, such as the position and spacing of the measuring points, etc., then manually leads the measurement, and installs the measuring points according to the detection plan. After the measurement is completed, analyze the data measured o...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that due to manual measurement errors, the installation position of the on-site measuring point deviates greatly from the installation position of the measuring point in the detection plan, resulting in the fact that the measured data and the calculated value are not in the same position, which in turn affects the analysis of the bridge's bearing capacity.
