文档介绍：简易数控直流电源
摘要:本实验设计了一个以单片机89C51为基本控制核心的简易数控直流电源。.该设计包括直流电源输入及输出两部分,可完成0~15V之间各不同幅值的电压的输出,能够预置数,能够自动扫描输出电压并直接显示到LED数码显示管上,并可扩展输出三角波等波型。其中电压输出部分,既可手动的每按”+””-”,也可长按”+””-”键使其自动的递增或者递减,直到需要的数值。预置数时用切换键切换预置个位或小数位,按”+””-”键进行微调。单片机编程部分是基于WAVE6000软件上设计,并在实物上进行仿真。.该系统具有抗干扰性能好,可靠性高,及最终输出电压值与真实显示值精确度较高等优点。

Abstract: This experiment has designed take monolithic integrated circuit 89C51 as the basic control core simple numerical control direct-current power supply. This design inputs and outputs two parts including the direct-current power supply, plete between 0~15V each different peak-to-peak value voltage output, the automatic scan output voltage and directly demonstrated on the LED numerical code display tube, and may expand the output triangle wave, and so on voltage type. voltage output unit, also may manual every time press "+" "-" the key to carry on each size about to adjust, also may long press "+" "-" the key to cause its automatic to increase progressively or to decrease progressively, until needs the value, carries on the trimming. monolithic integrated circuit programming part is again designs based on WAVE6000 software on, And carries on the test on the material object Debugging, This system has the resistance to interference well, the reliability is high, and finally output voltage value and real demonstration value precision higher merit.
