摘要
介绍了一种小型脉冲磁场屏蔽效能测试设备的原理、结构及参数 ,讨论了磁场测量波形的校正问题。系统采用光纤量测系统 ,有效减小干扰信号的影响 ;采用 Matlab编写自动测量及数据处理程序 ,实现了数据采集与处理自动化。实测校正值与理论值表明该系统可满足工程测量精度要求。
In order to measure the magnetic shielding effectiveness of buildings such as reinforced concrete construction, metal enclosure a portable measurement device was developed. The principle, structure, parameters are introduced here. The optic fiber system was used in the system. The measurement program was written in Matlab. Finally some measurement results were presented.
