摘要
介绍了管道爬行器的新定位系统———静磁场型定位系统。该定位系统由磁铁、霍尔传感器和信号处理与识别电路组成。它是利用管道外面的强磁场在管道内形成的漏磁场来产生定位信号。这种定位系统定位精度高 ,安全可靠 ,操作简便 。
A new intersect system which will be used in tube creeper is introduced,a static magnetic intersect system.The system is comprised by magnet,Hall element,signal distinguish and processing circuit.There are magnetic leakage inside tube with a strong magnet.Make use of small signal can intersect position of solder joint.This kind of intersect system has several features:higher intersect precision, safety and reliability, easy to handle and lower price.
