摘　　要：针对工频磁场测量的灵活性和便携性需求,提出了一种测量仪可任意姿态放置的工频磁场测量仪设计方案,该方案把加速度传感器和磁场传感器结合起来得到工频磁场水平方向和竖直方向上的分量,而无需对测量仪进行调平操作。该磁场测量仪包括三轴磁感应线圈、信号调理和A/D转换电路组成的磁场传感器模块及控制与处理模块、加速度传感器模块、存储和显示模块等部分。初步试验表明该方案可行,解决了传统工频磁场测量仪测量磁场水平分量和竖直分量需要调平的问题,结构简单、使用灵活,有一定的开发应用价值。For the requirements of flexibility and portability of power frequency magnetic field measurement,a design scheme of power frequency magnetic field measurement instrument which can place with arbitrary postures is proposed. The components in horizontal direction and vertical direction of the power frequency magnetic field are obtained by combining the acceleration sensor with magnetic field sensor in this scheme,and it is unnecessary to put the measurement instrument into leveling operation. The magnetic field measurement instrument is composed of magnetic field sensor module,control and processing module,acceleration sensor module,storage and display module,etc.. The preliminary experiment results show that the scheme is feasible. The problems of horizontal component and vertical component leveling operation needed by the traditional measurement instrument were solved. This measurement instrument has simple structure and flexible operation,and has certain development and application value.
