Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0022] Such as figure 1 As shown, the present invention proposes a deformation automatic monitoring system based on laser ranging, which is used to measure the relative deformation between the reference point 3 and the observation point 6, which consists of a laser transmitter 2, a laser receiver 5 and a data acquisition chip 1 constitute.

[0023] Specifically, such as figure 2 and image 3 As shown, the laser transmitter 2 is fixedly installed on the upper part of the reference point 3, and the laser transmitter 2 is connected to the data acquisition chip 1 with a wireless transmission module. The laser receiver 5 is placed on the upper part of the observation point 6, and the inside of the laser receiver 5 has a stepped laser receiving surface 7. The laser receiving surface 7 is made of transparent material. In the direction of laser emi...

Abstract

The invention relates to an automatic deformation monitoring system based on laser ranging, and the system comprises a laser transmitter, a laser receiver and a data acquisition chip. The system utilizes the current mature laser ranging technology to automatically measure the structural deformation, and overcomes the shortcomings of the existing common manual reading-based level / total station measurement method, which is subjectively affected by the measurement personnel, the shortcomings of the complex construction of a connection tube measurement method and the disadvantages of low measurement accuracy of GPS measurement method and the expensive operation of the displacement test method based on image processing, and improves the effect of deformation monitoring. The system is suitable for long-term deformation monitoring of bridges, culverts, roadbeds, tunnels, slopes, building construction and the like.

Description

technical field [0001] The invention belongs to the technical field of health monitoring in the construction industry, in particular to an automatic deformation monitoring system based on laser ranging, which is used to automatically measure the relative deformation (vertical or horizontal) between the observation point and the reference point, and is suitable for bridges and culverts , Deformation monitoring of dams, roadbeds, tunnels, slopes, housing construction and other projects. Background technique [0002] Deformation monitoring is widely used in the construction and use stages of modern roads, bridges and buildings, such as bridge deflection monitoring, house settlement monitoring, ground settlement monitoring, etc. In the prior art, the monitoring methods of structures and ground deformation can be roughly divided into the following four types: 1) level / total station measurement method based on manual readings 2) connected pipe measurement method 3) GPS measurement...
