摘　　要：针对同轴共面线圈装置中大发射磁矩与全波收录方式难以共存的问题,采用补偿线圈减弱一次感应磁场的方法,结合系统所需高精度、长时间连续采集的特点、利用状态机和多任务操作的关键技术,研发了以面向仪器系统的PCI扩展为核心的全波收录系统。实验表明系统稳定可靠,为方法研究提供了实践平台,为无人机和半航空电磁探测仪器的研发提供了参考。In this paper, considering the lack of compatibility between large magnetic moment and full-wave recording approach in coaxial coplanar coil devices, bucking coil is used to weaken the primary magnetic field. Then the key technology of state-machines and multitask operation is applied to develop the full-wave recording system with the core of PXI. In the development of the recording system, its characteristics of long period of continuous sampling and high-precision are taken into consideration. Experiments show that the system is stable and reliable, which provides an application platform for method research. It also provides reference for the design of electromagnetic instruments on unmanned aerial vehicles and semi-airborne.
