摘　　要：提出了一种以现代化的单片机控制技术为基础,结合D/A转换、模拟电子开关、功率放大、液晶显示和串行通信等技术实现对铁磁材料的磁滞回线进行测量的新方法,并在该方法的基础上成功设计并研制出一种新型智能励磁仪,将新仪器与分析仪、上位机等进行联机试验,结果表明新仪器具有更加友好的用户界面,所得实验数据的精度高、可靠性好。同时新仪器具有手动/自动两种工作模式,且可以实现与上位机的数据通信,自动化和智能化程度大大提高。A new method is presented, which is based on MCU control technology and combined with digital to analog conversion, analog electric switch, power amplifying, liquid crystal display and serial communication technology, to achieve the measurement of the Hysteresis loop. A type of new experimental instrument of Ferromagnetic materials is designed and fabricated successfully based on this new method. Make the new instrument tested with the analysis instrument and the host computer and the result of the test shows the new instrument has more user-friendly interface, the experiment data of the new instrument is more accurate and more reliable. New instrument has a manual/antomatic two operating modes and the data communication with the host computeris also can be realized by the new instrument. The degree of automation and intelligence is greatly enhanced.
