A system and method for monitoring the verticality of a tall frame based on a satellite positioning system

Abstract

The invention discloses a system and method for monitoring the perpendicularity of a tall frame based on a satellite positioning system. The system comprises a positioning monitoring system, wherein the positioning monitoring system comprises a measurement unit and a real-time operation unit; the measurement unit is used for obtaining geodetic coordinate values of at least three measurement pointsof the tail frame through the satellite positioning system, one measurement point is set as a new coordinate system origin and the other measurement points are defined as non-coordinate system origins; coordinate transformation is carried out on the measurement points of the non-coordinate system origins by using a geodetic coordinate of the new coordinate system origin and the geodetic coordinates of the non-coordinate system origins to obtain a real-time coordinate value in a new coordinate system; the measurement unit is used for outputting all obtained coordinate values to the real-time operation unit; and the real-time operation unit is used for receiving the coordinate values, transmitted from the measurement unit, of all measurement points, calculating the perpendicularity in realtime, comparing the perpendicularity with a set alarm threshold in real time and carrying out alarming in real time. The system and the method have the advantages that the requirements on the installation accuracy of equipment are low and monitoring of the perpendicularity of the tall frame is achieved.

Description

technical field [0001] The invention relates to a verticality monitoring system, in particular to a system and a method for monitoring the verticality of a tall frame based on a satellite positioning system. Background technique [0002] Whether it is expressway construction or high-rise building construction sites, such as tower cranes, etc., it has the characteristics of high structural height, complex and changeable force, low deformation omen, fast collapse speed, difficult monitoring, backward monitoring methods, and personnel cannot Active escape and other characteristics, and are greatly disturbed by external factors such as site geography and weather environment, are one of the most important safety risk sources that cannot be ignored on the construction site. Once the tall frame overturns, it will cause significant loss of life and property. In the relevant national standards and industry standards, there are monitoring standards and inspection requirements for the ...

AI Technical Summary

Problems solved by technology

[0006] (1) The national standard or industry regulations stipulate that theodolite or total station should be used to measure the tall frame. subjectivity

[0007] (2) The granularity of the monitoring cycle for tall and large structures in national standards or industry regulations is basically one month, but the environment on the construction site is complex and changeable. Considering the impact of weather, address environment, and on-site construction, the granularity of one month seems too large

[0008] (3) Under the existing technical conditions, there is a lack of real-time alarm measures. When the tall frame is about to overturn, the construction site lacks an emergency alarm device to remind personnel to evacuate

[0009] (4) There is a lack of statistical analysis of the verticality of tall and large frames, and advance warning cannot be achieved

The laser transmitter must be installed completely horizontally, otherwise there will be a large deviation in the calculation of the verticality

[0012] 2. High requirements for on-site use environment

[0013] 3. There is no real-time online monitoring data

The reading of data still needs manual work, and cannot be completed automatically, and cannot be observed and counted remotely in real time
