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
The present invention relates to laser technology field, specifically refer to a kind ofly, be applied to monitor the system of tall and slender structure integral inclination the combining of laser projections technology and camera technique, image processing techniques.
Background technology
Current, along with domestic and international architectural construction technology is constantly fast-developing, some projects under construction shorten the construction period for accelerating construction progress, often adopt operating technique means such as whole Transporting, integral slipping, integral hoisting.
Especially, adopt in whole construction process processes at some tall and slender structures, because of the centre of gravity place of these structures all than higher, in the integral construction process, as control improper or special circumstances occur, just might be because the excessive generation that causes accidents such as collapsing of structural entity inclination.Therefore, how the integral inclination of control structure just seems particularly important.Adopt which kind of method to come the integral inclination situation of monitoring structure just to become a new problem of monitoring technology.
Summary of the invention
Purpose of the present invention is to overcome the disappearance that above-mentioned prior art exists, and proposes a kind of combining of laser projections technology and camera technique, image processing techniques of utilizing, and is applied to monitor the system of tall and slender structure integral inclination.
Principle of the present invention is, at the top of tall and slender structure one laser projecting apparatus is installed, to structural base laser projections point being installed receives on the board and throws laser spots, shoot with video-corder the projecting laser point in real time by the high-pixel camera machine and observing the geometric figure that board top offset (position) changes relatively, and synchronous transmission is to the image pick-up card of computing machine, convert picture signal to digital signal by image pick-up card and software kit, and according to tilt angle calculation formula θ=arctg Δ/H, and then calculate tall and slender structure integral inclination value, show Monitoring Data and monitoring of structures top simulation heeling condition in real time, and early warning is provided.In case structural entity tilt displacement or angle of inclination are approaching or surpass the given alarming value of design, just can in time notify unit in charge of construction, take preventive measures, and take precautions against in possible trouble.
This apparatus system mainly comprises: laser projecting apparatus, laser projections point receives board and picture pick-up device and compositions such as image reception, demonstration, communication transmitting device system and computing machine (comprising corresponding software) and electric supply installation thereof.
In sum, this tall and slender structure integral inclination monitoring system, be applied in the engineering of tall and slender structure whole Transporting, slippage and lifting, can really accomplish to monitor in real time integral inclination displacement and the angle of inclination of large-scale tall and slender structure in the moving process of integral body, various Monitoring Data all are the Real-time and Dynamic reactions of space form in the structural entity moving process, have played good early warning.The blank of tall and slender structure integral inclination monitoring more than domestic hundred meters has been filled up by this system.
