Magnetic shielding room, remanence compensation model and remanence distribution adjusting method of magnetic shielding room based on remanence compensation model
The invention relates to a magnetic shielding room, a residual magnetism compensation model and a residual magnetism distribution adjusting method of the magnetic shielding room based on the residual magnetism compensation model. Wherein an independent residual magnetism adjusting coil is arranged on each of six shells of the magnetic shielding room, each residual magnetism adjusting coil is correspondingly connected with an independent current source, and according to a three-axis space distribution system, the six residual magnetism adjusting coils comprise two coils in the X-axis direction, two coils in the Y-axis direction and two coils in the Z-axis direction. The remanence adjustment distribution method for the magnetic shielding room comprises the following steps: firstly, establishing a remanence compensation model; based on three-axis residual magnetism space distribution, six compensation currents with the minimum residual magnetism and the highest distribution linearity are solved; adjusting current is introduced into the six independent residual magnetism adjusting coils, so that distribution adjustment of residual magnetism is completed. According to the residual magnetism distribution adjusting method, effective adjustment of residual magnetism in a large compensation area can be achieved in a small magnetic shielding room, and the effectiveness of the magnetic compensation technology is remarkably improved.
本发明涉及一种磁屏蔽房、剩磁补偿模型和基于剩磁补偿模型的磁屏蔽房剩磁分布调节方法。其中，所述磁屏蔽房的六面壳体上分别布置有一个独立的剩磁调节线圈，每个剩磁调节线圈对应连接独立的电流源，按照三轴空间分布体系，六个剩磁调节线圈包括两个X轴方向的线圈、两个Y轴方向的线圈和两个Z轴方向的线圈。用于上述磁屏蔽房的剩磁调节分布方法，首先建立剩磁补偿模型；再基于三轴剩磁空间分布，求解剩磁最小、分布线性度最高的六个补偿电流；通过向六个独立的剩磁调节线圈通入调节电流，完成剩磁的分布调节。本发明的剩磁分布调节方法，可在较小磁屏蔽房内，实现大补偿区域内剩磁的有效调节，显著提高磁补偿技术的有效性。
