一种动磁场磁测系统实现方法的研究与应用

Implementation and application of a dynamic magnetic integrated system

介绍了一种高频下集动磁场的产生、测量、控制于一身的动磁场综合磁测系统的实现方法,较好地解决了传统磁测方法在破坏性和非实时性等方面的缺点。该系统实现的难点及核心部分是高频交流动磁场激励源的设计制作,设计中充分利用了电力电子技术的发展成果,使用全桥逆变电路组成激励源的功率放大电路,激励源的主控部分运用单片机与FPGA配合运行的方案,具有控制合理、监督管理的实时性强等优点。结尾给出一工程实例,较好地说明了该实现思路的可行性和具体的使用效果。

This paper presents an integrated system realization method which can generate, control and measure high frequency dynamic magnetic field.It offers a solution to the traditional magnetic measurement method which is destructive and non-real-time. In the end of the project there gives an example to illustrate the feasibility of the method and specific use of results.
