Displacement monitoring device and measuring method thereof

Abstract

The invention discloses a displacement monitoring device comprising an image acquisition system, a network system, a power supply system and a computer system; the image acquisition system is responsible for image acquisition of an observation target mounted on a steam pipe, and the network system is responsible for network connection between a server and a control cabinet by using an optical fiber through a switch; the control cabinet is communicated with a camera through a network cable, the power supply system is mainly responsible for supplying power to the camera of the image acquisition system and the switch in the network system by a power supply device; compared with an existing relative displacement monitoring technology, the displacement monitoring device combines deep learning and binocular vision to realize high-precision monitoring of displacement of an object to be monitored. The accuracy of displacement monitoring is greatly improved, and the application range of deep learning is expanded. The method has the advantages of being good in applicability, wide in application scene and the like, and thus the technology has important application value for displacement monitoring of power plant boilers, steam turbine pipelines and other complex environments.

Description

Technical field[0001]The present application relates to the field of measurement, and more particularly to a displacement monitoring device, the present invention also relates to a method of measurement of a displacement monitoring device.Background technique[0002]The power plant boiler is one of the main thermal equipment of the fire power plant. The special refers to the high-tech boiler to the steam turbine in the power plant, and the start and stop of the boiler is an important part of the boiler operation, and the unit is quickly start and stop In the process, due to the difference in expansion of each of the various working ternations in the boiler, the deformation is constantly extruded, and when the internal effect of the boiler exceeds the boiler receiving range, it will cause the boiler to deform, damage or even tear. , Seriously affecting the policy operation of the unit, therefore, establishing a boiler expansion monitoring system is critical to ensuring the operation of...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a displacement monitoring device to solve the above-mentioned background technology. In the prior art, the boiler expansion monitoring mostly adopts a mechanical method, and the management personnel regularly inspects, collects data and informs the operator. There are many expansion monitoring points and they are far apart. The method of manual inspection is not only time-consuming and laborious, but also the obtained data is not real-time, which is not enough to provide real-time reference for power plant operators.
