摘要
介绍一种基于AT89S51单片机和新型数码管显示驱动芯片CH451构成的智能化相位差检测及显示的新方法。给出了系统的工作原理,着重介绍CH451的应用。本系统具有硬件电路结构简单,测量精度高,抗干扰能力强等特点。
A method of phase difference＇s intellectualized measurement based on AT89S51 microcontroller is introduced in this paper. A new kind of display driving chip CH451is adopted to compose the display circuit . The principle of the system hardware configuration, software flow chart are introduced and the CH451 is emphasizly introduced. This system has such characteristics as hardware circuit is of simple structure . It is high to measure the precision and the anti-lnterference can be good.
