【摘要】 根据一些社会现象,设计一种基于单片机的节能断电保护电路。该电路以单片机为控制核心,辅以相关的电子电路,利用人体红外传感器检测有无人在,或利用相关传感器检测计算机是否关机,当办公室、教室、学生宿舍无人时,或计算机关机但没断电时,延时一定的时间后,会自动切断电源,起到节能与断电保护的作用,下一次需要使用时,只要按一下开关即可恢复供电。更多还原

【Abstract】 Energy-saving research is the major topics to reduce cost and improve the economic efficiency.Pay attention to electricity safety and prevent the fire is an important problem that needs to value at all times.According to some social phenomena,the energy-efficient and power protection circuit based on single chip microcomputer is designed,which is controlled mainly by single chip microcomputer and supplemented by interrelated electronic circuitry.It can detect whether the exist of the human body or not by infrared sensors or detect whether the computer is closed or not by related sensors.when office,classroom or student′s hostels has no one,or computer is closed but no interruption of power supply,the curcuit can automatically cut off power supply after a period of time,and bring into play power protection and energy conservation function,when it needs to use in the next time,just click the switch,it can be able to resume power supply.更多还原
