以下具体说明上述一键开启电脑主机节能电源插座电路的工作原理:
首先将火线L和零线N端插头插入220V电源后,按动按钮开关AN1后,火线L的220V电压经按钮开关AN1接通后,经电容C1降压二极管D1~D4组成的二极管桥D,经电容C2滤波和稳压二极管VD1稳压后输出12V电压经电阻R3向电容C3充电,在电容C3充电的同时经电阻R4连接到三极管Q1的基极,使三极管Q1导通,12V电压经二极管D6连接到三极管Q1的发射极,三极管Q1导通后,集电极输出12V电压分两路,一路经二极管D7正向导通后输出高电平经电阻R5和电阻R6分压后使三极管Q2导通,使继电器J1得电工作,J1-1常开触点和J1-2常开触点同时吸合,J1-2常开触点吸合后,220V电压经J1-2常开触点吸合接通后经二极管D8~D11组成的电流检测电路输出220V电压连接到电脑主机开关电源U1电路输出SB5V电脑主板辅助5V待机电压,给无线接收器IC4的1脚供电脚供电,同时在三极管Q1导通后,集电极输出的12V电压另一路12V电压连接到无线发射器IC2的1脚,使无线发射器IC2得电发射无线信号,此时无线接收器IC4接收到无线发射器IC2发射的无线电信号,使无线接收器IC4的3脚输出高电平经电阻R10连接到三极管Q4的基极,使三极管Q4导通,使继电器J2得电工作,使J2-1常开触点吸合,J2-1常开触点和电脑主机的开启按钮开关AN2并联在一起,当J2-1常开触点吸合后,相当于人为按动了按钮开关AN2(电脑主机的开机按钮开关),此时电脑主机得到开机指示,电脑主机内开机电路启动,使电脑主机的开关电源U1电路内的主开关电源启动工作,输出主12V电压和主5V等电脑主板所需要的供电电压,使电脑主机正常开机,在电脑主机正常开机后,在二极管D8~D11组成的电流检测电路二极管的A和B两端将产生1.5V左右的电压经电阻R9降压后连接到IC1PC817光电耦合器的1脚,使光电耦合器IC1的内部发光二极管得电发光,光电耦合器IC1的3脚输出高电平向电容C5充电的同时经电阻R8限压使二极管D12得电正向导通,二极管D12的负极输出高电平经电阻R7和电阻R12分压后使三极管Q3导通,发射极输出高电平向电容C4充电的同时经电阻R5和电阻R6分压后连接到三极管Q2的基极,使三极管Q2保持导通状态,继电器J1保持得电工作,J1-1和J1-2常开触点保持吸合状态,当按钮开关AN1按动再松开,因继电器J1的J1-1常开触点与按钮开关AN1并联在一起的,所以按钮开关AN1断开后,但J1-1常开触点和J1-2常开触点会保持吸合状态,使电脑主机电源保持工作状态。而此时因电脑主机内开关电源U1的电脑主机待机5V电源得电工作,输出SB5V电压分两路,在给电脑主机供电的同时向无线接收器IC4供电,使无线接收器IC4接收到无线发射器IC2发射的信号,使无线接收器IC4的3脚输出高电平经电阻R10连接到三极管Q4的基极,使三极管Q4导通,继电器J2得电工作,J2-1常开触点吸合接通,因J2-1常开触点与电脑主机上的开机按钮开关并联,(按钮开关AN2为原电脑主机上的开关按钮开关)当J2-1常开触点吸合接通后,相当于按钮开关AN2接通,使电脑主机得到开机指令而正常开机。此时因电容C3在5秒钟后被充满电,此时三极管Q1截止,集电极无电压输出,使无线发射器IC2无电停止发射信号,使无线接收器IC4此时已接收不到无线信号,3脚输出低电平,使三极管Q4截止,继电器J2失电不工作,J1-1常开触点断开,从而实现自动开启电脑主机,使电脑主机正常开启后,CZ1为电脑显示器插座,使用时将电脑显示器的供电插头插入CZ1插座内即可。
当电脑主机正常关机后,电脑主机内主板会输出关机信号关闭电脑主机的开关电源U1电路的主+12V和主+5V电源无输出,只有电脑主机开关电源U1电路中输出SB5V待机5V电压供电脑主机内主板供电,使电脑主机处于待机状态。而此时在二极管D8~D11电流检测电路的A和B端只有0.3V电压,不能使IC1PC817光电耦合器内部发光管发光,3脚无法输出高电平,同时电容C5上所充电压也被电阻R8到地放完电,此时二极管D12截止,使三极管Q3截止,但电容C4将通过电阻R5和电阻R6分压使三极管Q2基极到发射极到地放电,使继电器J1保持得电工作,使J1-1常开触点和J1-2常开触点保持吸合状态,使电脑主机保持待机状态,大约1分钟后,电容C4被放完电,此时二极管Q2截止,继电器J1失电不工作,J1-1常开触点和J1-2常开触点断开,使电脑主机开关电源U1电路断电,同时也使CZ1插座断电,从而实现电脑主机关机后延时一分钟关闭电脑主机和电脑显示器的总电源,达到零功耗待机,节约用电和保护电脑主机。
以上显示和描述了本发明的基本原理、主要特征和本发明的特点。本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明的范围内。本发明要求保护的范围由所附的权利要求书及其等效物界定。
