基于虚拟仪器的海洋环境水下电磁场观测系统设计

摘要

海洋环境水下磁场观测已经广泛应用于海洋电磁学研究和舰船水下电磁场测试领域.本文介绍了基于虚拟仪器技术的海洋环境电磁场观测系统设计方案,利用LabVIEW软件设计、开发观测系统的测控软件；介绍了系统硬件结构及功能、软件的功能模块及流程图.基于虚拟仪器研制的观测系统完成了对海洋环境水下电磁场的长时间观测任务.%The observation of the marine underwater electromagnetic field has been widely used in the marine electromagnetism and the testing of the vessel' s underwater electromagnetic field. In this paper, the technical scheme of the marine electromagnetic field observation system based on the virtual instrument is introduced. The testing and control software is development by use of the Lab VIEW software. The hardware structure and function of the system is presented, the function module and flow chart of software is also introduced. The observation system based on the virtual instrument has been used in the long term measurement of the marine underwater electromagnetic field.
