Abstract

The invention provides a communication pipe deformation monitoring device and method. The device comprises a distance measuring apparatus, a fan-shaped guide rail and a main control apparatus. The fan-shaped guide rail is installed along the inner wall of the mouth of a communication pipe, and the distance measuring apparatus faces the interior of the pipe and is connected to the fan-shaped guiderail. The distance from the mount of the communication pipe to the tail end of the communication pipe is measured, and the distance measuring apparatus can move along the fan-shaped guide rail. The distance measuring apparatus is connected with a main control apparatus. A communication pipe deformation monitoring method comprises the steps: controlling a stepping motor to operate at a fixed time interval through the main control apparatus, driving the distance measuring apparatus to move from one end of the fan-shaped guide rail to the other end for one measurement; determining that there is no abnormality if the difference between the measured data and an initial value does not exceed a set threshold; determining that the abnormality happens if the differences between the measured data, obtained through three continuous measurements, and the initial value exceed the set threshold and the measured data obtained through three continuous measurements is the same, giving an alarm to an upper computer, and uploading the position of an abnormality. The measurement data is stable and reliable, and the method and device can achieve the direct early warning of the deformation trend.

Description

technical field

[0001] The invention relates to the technical field of deformation measurement of communication pipes, in particular to a device and method for monitoring deformation of communication pipes. Background technique

[0002] At present, manual monitoring of communication pipeline deformation is time-consuming and laborious, and it is impossible to realize real-time uninterrupted monitoring. It can only be inspected every once in a while; and there are few manual monitoring techniques and lack of corresponding instruments. Early warning. In most cases, the communication line is passively maintained after the communication is interrupted, and it is basically impossible to realize manual monitoring and early warning of the deformation of the communication pipeline. Because the material of the optical fiber itself is relatively brittle, the optical fiber is easily broken by external force when manually inspecting the line to find the fault location, so the deformati...
