Review of the Underground Pipeline Detectors Home and Abroad——Urgent Need for Designing Professional and Intelligent Instruments

摘要

The domestic market for underground pipeline detection is briefly analyzed,and then the theory and advantages of the FDEM underground pipeline detection are elaborated for a scientific analysis on the current status of the existing detection equipments home and abroad.The paper also points out that the exterior automatic detectors will necessarily not accustomed to the complexity of the pipeline configuration in our country,Therefore,the inevitable trend for the development of the underground pipeline detector is to design professional and intelligent instruments with intellectual property rights of our own.
