摘　　要：针对早期调压仪的笨重、操作复杂、显示落后等缺点,本文提出一种以AT89S51单片机和HEF4067的多路(复用)/多路输出选择器集成电路为核心,通过开机按键、模式按键、时间加减按键、强度加减按键等作为主要输入设备,用LED与数码管显示以及蜂鸣器等作为视听设备,经过外围电路元件,由单片机控制多路输出的智能低频调压仪器。该仪器实用、功能灵活多样,可以对电压幅度的状态进行调节以及控制,可以广泛的应用于人体按摩机或者其它场所的各种控制设备。The article is main introduction a kind of Micro Controller Unit,So-called single-chip AT89S51 （STC series compatible） and multiplexer to be double used, multiplexer choice selector integration circuit HEF4067 for center,through the start button, mode button, the key addition and subtraction of time, the intensity of plus or minus button,and so on, as a major input device, using LED, LED display and buzzer, etc. as audio-visual equipment, after the external circuit components, by the single-chip control of the output of multiple intelligent low-frequency voltage regulator. The apparatus practical, flexible and diverse functions, the voltage can range of state regulation and control, can be used in＇a wide range of massage or other place of a variety of control equipment.
