Description

System and Method for Non-Destructive Inspection of Water Pipeline with ICT The present invention relates to a water pipe non-destructive inspection system and method using ICT technology, and provides a water pipe non-destructive inspection system and method using ICT technology that enables remote monitoring and remote precision diagnosis through ICT-based water pipe non-destructive inspection, and ensures the safety of workers. Water pipes are essential infrastructure for daily life. If these pipes are damaged or defective, leading to a suspension of water supply or water contamination, it can cause significant harm to the lives of many people. Therefore, to ensure the safety of water pipes in advance, it is essential to inspect their condition through regular checks and detect defects early for repair or replacement. To this end, water pipes are currently being inspected using non-destructive testing methods. Non-destructive testing has the advantage of identifying damage or defects in water pipes without destroying them. Recent non-destructive testing using radiation involves irradiating water pipes with radiation and measuring the radiation penetration rate to detect defects, offering the advantage of accurately determining the location and size of such defects. However, since it involves generating and handling radiation, it has the disadvantage of requiring strict compliance with radiation safety regulations and potentially incurring additional time and costs for accessing the radiation space. Furthermore, there is a risk of radiation exposure for both the subject and the inspector. Additionally, radiation inspection has the disadvantage of being difficult to detect defects when they are small or complex.
