ABSTRACT 
The current electroplating technology is still has some problems,
such as the processing time is long, the less uniformity of plating
thickness, coating has defects, and so on, these problems not only affect
the electroplating products' quality, but also greatly limits the
electroplating technology development and application, therefore, we
hope to improve electroplating technology. Therefore this design designs
a new electroplating power - plating digital pulse electroplating power
that can improve the quality of plating , the power uses a AT89C51 as
a control core, that controls watch-dog circuit, key circuits, show
circuit , function controls circuit and the munication with the
second system, realize the control of the power; Watch-dog circuit uses
a MAX813L as the core, achieve the manual reset, electric reset, and
circuit monitoring; Button circuit uses a 4 * 4 matrix keyboard; Show
circuit uses a LCD1602 to display the power's dynamic; The second system
uses a AT89C2051 as the core, signals the switch tube; In order to reduce
the interference of analog signal interference to the circuit, the design
of the power circuit uses a photoelectric couplers. In theory, this system
can realize that electroplating voltage is adjustable, pulse time, pulse
duty cycle can control.

随着科学技术与生产的发展,电子技术在生产生活中应用的越来越多,在社
会生活中扮演日益重要的角色其中电镀产品就十分突出。但这些都是由于目前的
电镀技术仍存在诸如加工时间长、镀层厚度均匀性差、镀层容易出现缺陷以及存
在较大内应力等缺陷造成的,这些缺陷不仅影响到电镀制品的质量,同时还大大
限制了电镀技术的应用与发展,不能适应当前的社会生产,尤其是精密制造的需
要。因此,我们希望能改进电镀技术,从而提高电镀制品的质量。
虽然当今比较成熟而稳定的电镀电源为开关电源,但我们通过查阅相关资
料,对电镀生产的最基本原理进行研究,考虑到各方面因素,决定从生产实际进
行改革,通过采用先进的电镀电源,达到提高电镀生产的水平的目的,在提高电
镀制品质量的同
