摘要
介绍了非晶合金磁滞回线的平移现象,借助于电子仿真软件Proteus建立了仿真模型,仿真分析了非晶合金磁条产生偶次谐波的原理和决定因素。设计了基于非晶合金磁条的电子商品防盗系统。根据仿真结果,提出了系统设计的几个要点。经过实践测试,证实了仿真结果的真实性,为商品防盗系统的信号检测和识别提供了可靠的理论依据。
In this paper, the translation phenomenon of magnetic hysteresis loop of amorphous alloy is introduced in detail. The simulation model is established with the aid of electronic simulation software Proteus. The dominant factor and principle of the even-harmonic from amorphous alloy magnetic bar are analyzed by simulation. An electronic surveillance system based on amorphous alloy magnetic bar is designed. Several essential points of system design are shown on the basis of simulation result. The correctness of simulation result is confirmed by practical test. A reliable theoretical basis is provided for signal detection and object identification of electronic surveillance system.
