摘　　要：设计以单片机(AT89S52)作为控制系统,实现对电压、电流检测和显示控制。充电的电压和电流通过A/D转换器MAX187采样后送单片机,完成对输出数据检测和显示,可以方便地实现充电状态的切换。采用温度传感器DS18B20作为温度测量电路,显示采用中文液晶显示器OCMJ4×8C,并有开机检测功能,提供良好的工作界面。该充电电源具有控制功能强、性能稳定可靠、性价比高等优点。The design is based on SCM （ AT89S52 ） as a control system,to achieve the voltage,current detection and dis- play control. The charging voltage and current through the A/D converter MAX187 sampling evacuation mieroeontroller, the completion of the output data detection and display, can easily realize the charge state of the switch. Using the temper- ature sensor DS18B20 as the temperature measurement circuit, display the Chinese LCD OCMJ4 X 8C, and start-up detec- tion function,provides a good inter{ace. The charging power supply has the advantages of high control function is strong, stable and reliable performance, cost-effective.
