摘　　要：针对双磁芯磁通门式测磁仪需要定期精度检测和调校的情况,设计了一种便携式智能化双磁芯磁通门式测磁仪测量精度检测方法。该方法通过在测磁仪出厂后首次使用前,对其测量线圈中施加标准电流以产生标准磁场,该标准磁场与环境磁场叠加后由测磁仪测量输出,当标准电流变化时,测磁仪的测量值也随之变化,将这种变化产生的曲线标定为测磁仪对磁场的测量精度检测曲线,该曲线即可作为测磁仪的精度检定标准。该方法使双磁芯磁通门式测磁仪的测量精度能全时域受控,从而使测磁工作能高效率、高质量的完成。In view of the need for regular precision testing and tuning of the dual core fluxgate magnetometer,a test method for measuring accuracy of the instruments is proposed.In this method,the standard current is applied in the measuring coil of the magnetometer,as a result,the standard magnetic field in the measuring coil is produced,and then the magnetic field mixed the environmental magnetic field is measured by the magnetometer,so the measured magnetic field should vary with the standard current.The change curve can be calibrated as the detection curve of the accuracy of measurement.The method can make the measurement accuracy of the dual core fluxgate magnetometer to be controlled in full time domain,and make the magnetic field measurement efficient.
