摘要
对磁记忆检测技术原理及技术难点进行了介绍,通过阵列探头设计和信号处理手段解决了磁信号微弱的问题.采用阵列探头能够排除外界磁信号干扰,同时确保信号之间的一致性.经验证,这种设计能够获得埋地管道的地表磁场分布图,确定异常磁信号来源.所研制检测仪器能够有效进行埋地管道弱磁信号检测.
The principle and technical difficulties of magnetic memory testing technology are introduced,the problem of weak magnetic signal is solved by means of array probe design and signal processing.Array probe can eliminate external magnetic signal interference,ensure the consistency between signals.This design can obtain the surface magnetic field distribution map of buried pipeline,also the source of abnormal magnetic signal can be confirmed.The developed instrument can effectively detect the weak magnetic signal of buried pipeline.
