How many types of pipeline inspection are roughly classified？

Pipeline inspection is roughly divided into the following categories：

1. Borehole Pipe Inspection Camera, This type of detection is mainly the use of convenient stretchable, extended internal camera of the pipe, The Borehole Pipe Inspection Camera can be carried in a portable engineering box. The camera size can be adapted to any pipe size from 10MM to 500MM. The camera has high-definition, built-in light supplement system, waterproof, self-balancing, suitable for pipes in any environment, and measurement distance It can reach 150 meters, and the integrated display, controller, and control terminal can effectively collect and store high-definition image data in real time. The equipment on the water supply and drainage, industrial pipeline measurement effect is very good, mainly its cost-effective is relatively high, affordable, powerful, in today's era of non-excavation technology is slowly prevailing, such detection methods are characterized in a group of pipeline maintenance and non-excavation evaluation testing has great significance and prospects.

2.CCTV detection technology: First of all, CCTV is not China Central Television, it is the shorthand for CCTV, as the name implies, it is a form of camera video to the structure of the pipeline inside the environment to do an image processing, more intuitive understanding of the situation, The principle is simple, that is, through the camera's camera video recording, the data is transmitted via cable to the display control terminal, and then the image processing. The system consists of a camera, a crawler (crawler), a data cable, a control terminal (including a controller, display, computer, etc.). The advantage of this method is to simplify the inspection work, simple operation, accurate data, and reduce some on-site construction risks. At present, foreign countries are more popular than domestic applications. 

Foreign countries have met the requirements of annual census. Some domestic first-tier cities have carried out demonstration work, such as Shanghai, Shenzhen and other cities. However, the domestic market is not long after its start, and there is a lot of market space in the future.
