摘要
为验证各向异性磁阻传感器在地磁探测过程中的灵敏度和精确性,基于各向异性磁阻传感器的工作原理,利用霍尼韦尔Hmc1001型磁阻传感器分别对地表裸露金属物、地下埋藏金属物以及地下未知管线进行了探测实验。实验表明,各向异性磁阻传感器提高了同类探测的精度,对地下可疑物进行相关探测行之有效。
In order to verify the sensitivity and precision of the anisotropic magnetoresistive sensor in survey of geomagnetism;based on operational principle and properties of anisotropic magnetoresistive sensor,by using Honeywell Hmc1001 sensor,exploring experiments have been taken for surface exposed metal object,underground metal object,and underground unknown pipeline.The experiments indicate that anisotropic magnetoresistive sensor enhances the accuracy of similar survey,so it is feasible and effective for exploring suspicious objects underground.
