The device has the advantages that convenience is brought to carrying and installation; the application range is wide, the adaptability is high, and the service life is long; the measurement method is simple, and the result is accurate; deformation and displacement in three directions can be detected at the same time, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of equipment detection, and in particular relates to a non-contact displacement detection device based on image recognition technology and a method for detecting the displacement of a device under test using the device. Background technique [0002] Various field equipment (such as: GIS equipment, oil pipelines, etc.) are exposed to the field for a long time, and their failure frequency is relatively high. Most of the failure reasons are caused by thermal expansion and cold contraction of equipment. Due to the influence of the temperature difference between day and night, the equipment in the field will have a large displacement and deformation, which will cause a series of problems such as bending and cracking of the equipment. Before the problem is eliminated, the operation and maintenance personnel of the equipment will invest a lot of manpower and material resources to ensure the normal operation of the equipment,...

AI Technical Summary

Problems solved by technology

The contact sensor needs to be in contact with the device under test to accurately measure data, but the field environment is more complicated, and the sensor will fail or be damaged in bad weather, resulting in low work efficiency and increased work costs

Furthermore, traditional conventional displacement detection devices often use an external power supply. When working in the field, it is very troublesome to connect the power supply. At the same time, the power supply wire leaks outside. Under the harsh conditions in the field, it is easy to damage and is not easy to carry.
