摘要
基于电梯平衡系数的测试原理,设计开发一种新型测试仪。根据测试仪功能要求,介绍了用单片机AT89C51、键盘/显示管理芯片HD7279A以及A/D转换芯片ICL7135等设计的电梯平衡系数测试仪硬件测试系统的设计方法,同时给出了系统软件的程序流程图。
On the basis principle of elevator equilibrium coefficient to design a new measure instrument. According to the function demand of the measure instrument to introduce the design method which through the use of SCM AT89C51, keyboard/ show manage CMOS ship, HD7279A and A/D transition CMOS chip ICL7135 to design the hardware measure system of elevator equilibrium coefficient testing instrument and give the procedure flow chart of the system software as meanwhile .
