Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be further described

[0018] The present invention is a towering structure laser projection overall inclination monitoring system (as attached figure 1 As shown), in a blast furnace overhaul project, the overall disassembly and assembly (including overall jacking, sliding, lifting and transportation) process of the blast furnace roof structure with a length × width × height of 22m × 22m × 60m was realized.

[0019] The system of the present invention includes a laser transmitter 1 installed at the top of the structure, and ensures that the projected laser is vertically downward to the receiving target plate 2 of the laser projection point provided at the bottom of the structure, and its ideal position is the exact center point. It’s okay to have a slight deviation, but it can’t deviate too far from the center point to prevent the overall tilt from exceeding the receiving range of t...

Abstract

The invention discloses a system for monitoring overall tilting of a high-rise structure through laser projection, which relates to the technical field of laser. The invention particularly relates to a system for monitoring the overall tilting of the high-rise structure, which combines a laser projection technique, a photographic technique and an image processing technique. The system comprises a laser projector (1), a laser projection point receiving sighting board (2), a picture pick-up device (3), a computer (4) and a power supply unit (5), wherein the picture pick-up device (3) has high pixels, comprises image transmission and is connected with the computer (4) through electric signals; and the computer (4) comprises an image acquisition card, software for performing operation according to an inclination angle formula theta=arctg delta / H, and a display used for real-time monitoring. The system can display monitoring data and imitate a dynamic tilting state of a monitored structure in real time, provide early warnings, and can notify a construction unit in time to take preventive measures for nipping in the bud once the overall tilt displacement or the inclination angle of the structure is close to or exceeds a designed given alarm actuation value.

Description

technical field [0001] The invention relates to the field of laser technology, and specifically refers to a system that combines laser projection technology, camera technology, and image processing technology to monitor the overall inclination of a towering structure. Background technique [0002] At present, with the continuous and rapid development of construction technology at home and abroad, in order to speed up the construction progress and shorten the construction period, some construction projects often adopt construction techniques such as integral transportation, integral sliding, and integral hoisting. [0003] In particular, in the overall construction process of some towering structures, because the center of gravity of these structures is relatively high, in the overall construction process, if the control is not proper or special circumstances occur, it may cause collapse due to the overall tilt of the structure. Accidents happen. Therefore, how to control th...
