摘要
用脉冲峰值微分过零法检测峰值,单片机采集数据,图形液晶显示磁滞回线,研制静态磁滞回线测试仪,电路简洁,测量准确,结果直观。文中介绍该测试仪的工作原理、部分电路,给出实验结果。
A static hysteresis loop test instrumentation is developed, detecting pulse peak by method of cross-zero of pulse peak after differential, acquiring data by microcontroller, displaying hysteresis loop by graphic LCD The test instrumentation has advantages of simple circuit, accurate measurement and visual result. The operating principle and partial circuits are intro- duced, and the experimental result is given.
