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.視頻內(nèi)窺鏡日益普及

1. Video endoscopes are becoming more and more popular、

工業(yè)內(nèi)窺鏡的種類比較多樣化。上個(gè)世紀(jì)90年代之前，直桿鏡和光纖鏡這兩種光學(xué)內(nèi)窺鏡產(chǎn)品在航空航天等領(lǐng)域應(yīng)用較多，但是后來數(shù)字化技術(shù)的發(fā)展推動(dòng)了視頻內(nèi)窺鏡的出現(xiàn)及應(yīng)用，不僅可以實(shí)時(shí)觀察，還可以拍照和錄制視頻，使得檢測(cè)過程具有了可存儲(chǔ)、可復(fù)現(xiàn)、可分享的特點(diǎn)，比光學(xué)內(nèi)窺鏡方便很多，因此現(xiàn)階段視頻內(nèi)窺鏡（電子內(nèi)窺鏡）是主流設(shè)備，應(yīng)用比較廣泛，很多企業(yè)在購(gòu)買時(shí)都優(yōu)先選擇視頻內(nèi)窺鏡。

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.缺陷測(cè)量技術(shù)得到重視

2. Attention has been paid to defect measurement technology

起初的工業(yè)內(nèi)窺鏡設(shè)備，主要用于查找設(shè)備或管道內(nèi)部有無缺陷，后來隨著檢測(cè)水平的提升以及各行業(yè)安 全要求的提升，已經(jīng)不再滿足于定性判斷，而是希望有確切的數(shù)據(jù)輔助分析設(shè)備狀況，特別是對(duì)于處于臨界狀態(tài)的設(shè)備，因此缺陷測(cè)量技術(shù)逐漸得到了重視?，F(xiàn)階段很多內(nèi)窺檢測(cè)設(shè)備都具備缺陷測(cè)量能力，比較的是相位掃描三維立體測(cè)量技術(shù)，能夠?qū)α鸭y長(zhǎng)度、腐蝕坑深度、損傷面積等進(jìn)行更為準(zhǔn)確的測(cè)量。

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.

3.一機(jī)多用更經(jīng)濟(jì)

3. One machine with multiple uses is more economical

對(duì)于內(nèi)窺鏡來說，一機(jī)多用的概念更多地體現(xiàn)在不同探頭的復(fù)用上。通過更換探頭技術(shù)，很多不同規(guī)格、不同用途的探頭可以更換到同一臺(tái)內(nèi)窺鏡設(shè)備上，也就是一臺(tái)內(nèi)窺鏡設(shè)備可以根據(jù)現(xiàn)場(chǎng)需求換用不同的探頭，例如：不同長(zhǎng)度不同直徑的探頭、開展熒光檢測(cè)的UV探頭、可以?shī)A取異物的機(jī)械手探頭、帶有打磨工具的探頭、以及其他定制型探頭等。對(duì)于用戶來說，一方面擴(kuò)展了設(shè)備的應(yīng)用場(chǎng)景，另一方面也有助于控制成本。

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.

上面這些特點(diǎn)，在當(dāng)今市場(chǎng)的很多工業(yè)內(nèi)窺鏡產(chǎn)品上都得以體現(xiàn)。例如：工業(yè)視頻內(nèi)窺鏡是基于CCD成像的電子工業(yè)內(nèi)窺鏡，支持多種測(cè)量功能，而且也可以靈活更換不同的探頭。

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.
