Inspired by the fact that medical endoscope can detect human lesions without damage, industrial endoscope equipment came into being. The small insertion tube or probe penetrates into the interior of industrial equipment or pipeline, and the detection image is transmitted and output through optical path or digital signal cable and presented in front of the detection personnel, which realizes the extension of human eye sight and the change of visual direction, expands the application scope of visual detection, and helps the detection personnel faster More accurately find defects and damages inside equipment or pipelines. After these years of development, what are the characteristics of industrial endoscope equipment at this stage?
1. Video endoscopes are becoming more and more popular、
The types of industrial endoscopes are diversified. Before the 1990s, straight rod endoscope and fiber optic endoscope were widely used in aerospace and other fields, but later the development of digital technology promoted the emergence and application of video endoscope, which can not only observe in real time, but also take photos and record video frequency, making the detection process storable, reproducible and shareable, It is much more convenient than optical endoscope. Therefore, at this stage, video endoscope (electronic endoscope) is the mainstream equipment and is widely used. Many enterprises give priority to video endoscope when purchasing.
2. Attention has been paid to defect measurement technology
At first, the industrial endoscope equipment was mainly used to find out whether there were defects in the equipment or pipeline. Later, with the improvement of the detection level and the safety requirements of various industries, it is no longer satisfied with qualitative judgment, but hopes to have accurate data to assist in the analysis of equipment conditions, especially for the equipment in critical state. Therefore, the defect measurement technology has been paid more and more attention. At present, many endoscopic inspection equipment have defect measurement ability. The more advanced is the phase scanning three-dimensional measurement technology, which can more accurately measure the crack length, corrosion pit depth and damage area.
3. One machine with multiple uses is more economical
For endoscopes, the concept of one machine with multiple functions is more reflected in the reuse of different probes. By replacing the probe technology, many probes of different specifications and different purposes can be replaced on the same endoscope equipment, that is, an endoscope equipment can be replaced with different probes according to the site requirements, such as probes with different lengths and diameters, UV probes for fluorescence detection, manipulator probes that can clamp foreign matters, probes with grinding tools And other custom probes. For users, on the one hand, it expands the application scenario of the device, on the other hand, it also helps to control the cost.
These characteristics are reflected in many industrial endoscope products in today's market. For example, industrial video endoscope is an electronic industrial endoscope based on CCD imaging. It supports a variety of measurement functions, and can also flexibly replace different probes.
