流体驱动智能管道内检测机器人关键技术及应用.

It is an important and effective means to use a pipeline internal robot driven by the pipeline′s own fluid and equipped with magnetic flux leakage detection equipment to carry out long-distance transmission pipeline detection.The principle of pipeline magnetic flux leakage internal detection, algorithm of defect magnetic flux leakage and driving force of internal detection robot were introduced.Through adaptability, speed control and magnetic flux leakage detection module design related to defect detection effect, the results of the above project were applied to practical industrial practice.The results show that the internal detection robot developed in this project has stronger detection adaptability and can further improve the detection sensitivity and resolution of defects, which can be popularized and applied in the industry.
