我国未探明的矿产资源基本分布在深部矿或隐伏矿中，为提高常用磁法探测的深度和精确度，采用灵敏度为fT量级的超导量子干涉仪作为磁传感器则是目前最理想的解决方案。本文针对在无磁屏蔽环境中，尤其是航空平台，如何能在满足超导地球物理勘探设备的动态范围和电磁兼容要求的前提下最大程度地发挥SQUID灵敏度优势的问题，在国内首次将图形化系统设计平台应用于低温超导地球物理勘探中，并基于CompactRIO和PXI的可重配置平台和丰富的信号采集控制模块，利用NI LabVIEW开发出一套适用于超导地球物理勘探的图形化测控生态系统，实现了多通道fT量级磁场的同步数据采集与分析，从而有效地保障了国家深部探测专项的实施。

Domestic undiscovered mineral resources almost distribute in deep buried or concealed deposit. In order to improve the detection depth and accuracy of the common magnetic exploration, using extremely sensitive superconducting quantum interference device (SQUID) as the magnetic sensor is currently the best solution. In this paper, aiming at the problem which is how to maximize the advantages of the SQUID sensitivity under the premise of meeting the requirements of superconducting geophysical exploration equipment in dynamic range and electromagnetic magnetic compatibility (EMC), a graphical system design platform solution based on LabVIEW is first proposed in China and a graphical measurement and control ecosystem based on the CompactRIO and PXI reconfigurable platform and their rich signal acquisition and control modules have also been developed to achieve synchronous data acquisition and analysis of multi-channel magnetic field as low as several fT, thus effectively safeguarding the implementation of the national deep exploration special project.
