Problems solved by technology

[0003] At present, there are many methods to measure the displacement of the slope, which can be mainly divided into the displacement measurement of the inclination hole and the displacement measurement of the fiber grating. However, the operation process of the displacement measurement of the inclination hole is complicated, and personnel are required to carry out on-site measurement, and the displacement of the slope cannot be monitored in real time. situation, poor hysteresis
Optical fiber sensing technology is to realize the measurement of environmental parameters by measuring the changes of certain parameters (such as intensity, phase, frequency, etc.) of the light transmitted in the optical fiber. Although it can realize automatic monitoring, it can only realize displacement measurement in two directions. Moreover, the technical application is not yet perfect, often causing the fiber grating to be broken, and the cost is huge, so there are certain limitations
In addition, there are surface displacement measurement methods such as GPS measurement method and total station, but the measurement results only reflect the results of the slope surface, and the results have certain limitations

Abstract

The invention discloses an automatic monitoring device for slope displacement, and the device comprises an inclination measuring pipe, wherein the top of the inclination measuring pipe is provided with a rotary coder. The rotary coder is fixed, and is connected with a measurement line. The measurement line can extend to the bottom of the inclination measuring pipe from the top of the inclination measuring pipe. The rotary coder measures the displacement of a slope on the Z axis through the measurement line, and the rotary coder is connected with a data receiver. The displacement data measured by the rotary coder on the Z axis is transmitted to the data receiver. The invention also discloses an application method. The device can measure the deep displacement of the slope, can reflect the change condition of the displacement of the slope in a better manner, provides a better instruction for the monitoring warning, is higher in usability, and is wider in application range.

Description

technical field [0001] The invention relates to an automatic monitoring device for displacement, in particular to an automatic monitoring device for slope displacement and a method for using the same. Background technique [0002] my country is a mountainous country, and landslide geological disasters are serious and widely distributed. Landslides are extremely destructive, causing heavy casualties and huge economic losses. In order to accurately evaluate the relationship between slope displacement activities and landslides and other geological disasters To understand the overall displacement of the slope, it is necessary to accurately understand the displacement changes in all directions of the slope. [0003] At present, there are many methods to measure the displacement of the slope, which can be mainly divided into the displacement measurement of the inclination hole and the displacement measurement of the fiber grating. However, the operation process of the displacement ...
