摘要
针对原有微波测量教学实验装置进行自动化改造设计,形成以单片机8051为控制中心,由步进电机伺服系统、信号调理电路、液晶显示部分及数据分析软件等构成的微波自动测量系统,实现了自动测量并在液晶屏上显示测量线的场强波形或阻抗圆图等。该微波自动测量系统界面友好,操作简单,在速度、精度及重复性等方面较手动测量系统有很大的改善,具有很强的实用性,满足了实验教学的需求。
This paper introduces a microwave automatic measurement system which is developed based on original teaching experiment system for microwave measurement.SCM 8051 is formed as control center of this system.The system consists of stepping motor servo system,signal processing circuit,LCD,data analysis software and so on.Automatic measurement is realized and field intensity waveform or Smith Chart of the system is displayed on LCD.This microwave automatic measurement system has friendly interface and simple operation.Compared with manual measurement system,the rapidity,precision and repetition of this system are greatly improved.The system has strong practicality and satisfies the requirement of the experiment teaching.
