摘　　要：提出了一种以ATmega328P单片机为主体的电源开关定时系统的设计方法,主要应用于小家电供电控制。系统以Arduino Nano开发板为基础,采用ATmega328P单片机为核心控制器件;使用5 V继电器以及电容式触摸开关联合对小家电电源实现人工和定时两种通断控制;采用OLED液晶显示屏实时显示菜单选项和定时的时长。另外,系统提供了功能选择和设置定时按键,并配有蜂鸣器电路为定时结束提示。该系统由电容式触摸感应开关和按键开关作为信号输入部分,负责采集电源人工启停信号和定时信息;由单片机控制核心进行信息分析、处理及判断,并给出相应输出控制;系统输出部分包括显示模块、继电器控制模块和提示音模块,在输出控制信号的作用下联合完成人机交互、电源的人工通断和定时通断等功能。系统仿真和实物测试结果表明,本系统可有效地实现电源定时通断的需求,可达到合理使用电力资源的初衷。A design scheme of power switch timing system based on ATmega328P microcontroller is proposed,which is mainly used in the power supply control of small household appliances.The system is based on the Arduino Nano development board,and uses ATmega328P microcontroller as the core control device.5 V relay and capacitive touch switch are used to achieve manual and timing on-off control of the power supply of small household appliances;The OLED LCD display is used to display menu options and timed durations in real time.Function selection and setting timing buttons are set in the system,together with a buzzer circuit for timing prompt.The system consists of capacitive touch sensor switch and key switch as the signal input part,which is responsible for collecting the manual start and stop signal and timing information of the power supply;the collected signal is analyzed,processed and judged in the microcontroller,and the corresponding output control is given.The output part of the system includes a display module,a relay control module and a prompt sound module,which jointly completes the functions of human-computer interaction,manual on-off and timing on-off of power supply under the action of output control signals.The system simulation and product test results show that the system can effectively realize the demand of power supply timing on and off,and can achieve the original intention of rational use of power resources.
