摘要（英）：

Relating to the field of chemical gathering and transportation pipeline fault detection, the invention provides a transient electromagnetic pipeline defect scanning method and device. The device includes a transient electromagnetic host, an array sensor assembly and a data processing terminal. The transient electromagnetic host receives a starting signal and sends detection output pulse according to the starting signal. The array sensor assembly receives and sends the detection output pulse, generates array feedback pulse and displacement data, and sends array feedback pulse and displacement data. The transient electromagnetic host also receives array feedback pulse and displacement data, generates pipeline detection data according to the array feedback pulse and displacement data, and sends pipeline detection data. The data processing terminal generates pipeline defect information and pipeline 3D graphic information according to the received pipeline detection data. The technical scheme alleviates the problems of poor detection point location accuracy and long detection process time, realizes comprehensive scanning of the gathering and transportation pipeline, ensures the accuracy of detection point layout and improves the detection efficiency.
