在本实施例中，刷机装置110依据第一触发信号和第二触发信号实现开机动作和还原动作的具体原理为：当第一触发信号为非开机信号且第二触发信号为还原信号时，第一逻辑判断单元1111配置成依据还原信号和非开机信号生成第一逻辑判断信号；分压电路1112配置成对第一逻辑判断信号进行分压处理，生成第一分压信号；第一比较单元1113配置成依据第一分压信号和还原信号生成第一比较信号，以使还原控制模块150依据第一比较信号进行还原动作；第二逻辑判断单元1121配置成依据还原信号和非开机信号生成第二逻辑判断信号；第二比较单元1122配置成依据第一分压信号和第二逻辑判断信号生成第二比较信号；反相单元1123配置成依据第一逻辑判断信号生成第一反相信号，以使开机控制模块140根据第二比较信号和第一反相信号进行开机动作。
如表1所示，当第一触发信号PHONE_ON为非开机信号且第二触发信号Recovery为还原信号时，即用户触发还原按键，使得还原按键产生为低电平的还原信号，由于用户未触发开机按键，故开机按键产生为高电平的非开机信号。第一逻辑判断单元1111根据还原信号和非开机信号对应生成为高电平的第一逻辑判断信号，即此时的第一处理信号Boot_OR为第一逻辑判断信号；第二逻辑判断单元1121根据还原信号和非开机信号对应生成为低电平的第二逻辑判断信号，即此时的第三处理信号Boot_AND为第二逻辑判断信号；分压电路1112对第一逻辑判断信号进行分压处理，得到电平高于第二逻辑判断信号和还原信号的第一分压信号，即此时的第二处理信号Boot_OR_1为第一分压信号；第一比较单元1113依据第一分压信号和还原信号生成为低电平的第一比较信号，即此时的第二控制信号Recovery_ON为第一比较信号；还原控制模块150依据为低电平的第二控制信号Recovery_ON进行还原动作；第二比较单元1122依据第一分压信号和第二逻辑判断信号生成为低电平的第二比较信号，即此时的第四处理信号Boot_ON_2为第二比较信号；反相单元1123依据第一逻辑判断信号生成为低电平的第一反相信号，即此时的第五处理信号Boot_OR_2为第一反相信号；由于第二比较信号和第一反相信号输入开机控制模块140的相同端口，且因第一反相信号和第二比较信号均为低电平，故此时的第一控制信号Boot_ON为低电平；开机控制模块140根据为低电平的第一控制信号Boot_ON进行开机动作。

在本实施例中，当第一触发信号PHONE_ON为开机信号，第二触发信号Recovery为还原信号时，第一逻辑判断单元1111配置成依据开机信号和还原信号生成第三逻辑判断信号；分压电路1112配置成对第三逻辑判断信号进行分压处理，生成第二分压信号；第一比较单元1113配置成依据第二分压信号 和还原信号生成第三比较信号，以使还原控制模块150依据第三比较信号不进行还原动作；第二逻辑判断单元1121配置成依据开机信号和还原信号生成第二逻辑判断信号；第二比较单元1122配置成依据第二分压信号和第二逻辑判断信号输出不确定的信号；反相单元1123配置成依据第三逻辑判断信号生成第二反相信号，以使开机控制模块140依据不确定的信号和第二反相信号不进行开机动作。
如表3所示，当第一触发信号PHONE_ON为开机信号，第二触发信号Recovery为还原信号时，即用户触发开机按键，使得开机按键产生为低电平的开机信号，用户触发还原按键，还原按键产生为低电平的还原信号。第一逻辑判断单元1111根据还原信号和开机信号对应生成为低电平的第三逻辑判断信号，即此时的第一处理信号Boot_OR为第三逻辑判断信号；第二逻辑判断单元1121根据还原信号和开机信号对应生成为低电平的第二逻辑判断信号，即此时的第三处理信号Boot_AND为第二逻辑判断信号；分压电路1112对第三逻辑判断信号进行分压处理，得到电平与第二逻辑判断信号和还原信号相等的第二分压信号，即此时的第二处理信号Boot_OR_1为第二分压信号；第一比较单元1113中的第一比较器U1依据第二分压信号和还原信号生成电平不确定的信号，由于第一电阻R1的一端与电源电连接，故会将第一比较器U1输出的不确定信号拉高为高电平的第三比较信号，即此时的第二控制信号Recovery_ON为第三比较信号；还原控制模块150依据为高电平的第二控制信号Recovery_ON不进行还原动作；第二比较单元1122依据第二分压信号和第二逻辑判断信号生成电平不确定的信号，即此时的第四处理信号Boot_ON_2为电平不确定的信号；反相单元1123依据第三逻辑判断信号生成为高电平的第二反相信号，即此时的第五处理信号Boot_OR_2为第二反相信号；由于电平不确定的第四处理信号Boot_ON_2和第二反相信号输入开机控制模块140的相同端口，且因第二反相信号为高电平，第二反相信号会将第四处理信号Boot_ON_2拉高为高电平信号，故此时的第一控制信号Boot_ON为高电平；开机控制模块140根据为高电平的第一控制信号Boot_ON不进行开机动作。

表4
为了防止反相单元1123生成的第五处理信号影响到第二比较单元1122，以及防止第二比较单元1122生成的第四处理信号影响到反相单元1123。请参照图4，为本公开实施例提供的刷机装置110的另一种可实施的电路示意图，图4所示的刷机装置110与图3所示的刷机装置110的区别在于，开机处理模块112还包括防倒流单元113，第二比较单元1122和反相单元1123均通过防倒流单元113与开机控制模块140电连接。
在本实施例中，第二比较单元1122配置成通过防倒流单元113向开机控制模块140提供第四处理信号；反相单元1123配置成通过防倒流单元113向开机控制模块140提供第五处理信号。由于防倒流单元113具有防止电流倒流的功能，故第二比较单元1122产生的第四处理信号Boot_ON_2不能倒流至反相单元1123，而反相单元1123产生的第五处理信号Boot_OR_2不能倒流至第二比较单元1122。
图4为本公开实施例提供的另一种可实施的刷机装置110的电路原理图。防倒流单元113包括第一二极管D1和第二二极管D2，反相单元1123的输出端与第一二极管D1的阳极电连接，第二比较单元1122的输出端与第二二极管D2的阳极电连接，第一二极管D1的阴极和第二二极管D2的阴极均与开机控制模块140电连接。
可以理解，第一二极管D1配置成防止第二比较单元1122产生的第四处理信号Boot_ON_2倒流至反相单元1123，第二二极管D2配置成防止反相单元1123产生的第五处理信号Boot_OR_2倒流至第二比较单元1122。
请参阅图5，为本实施例提供的电子设备100的一种可实施的结构示意图，该电子设备100包括还原触发模块130和开机还原装置100A，还原触发模块130与开机还原装置100A电连接。还原触发模块130配置成向开机还原装置100A提供还原信号，开机还原装置100A配置成依据还原信号获得工作电压并进行还原操作和开机操作。
在本实施例中，该电子设备100可以为笔记本电脑及平板电脑等。还原触发模块130可以包括还原按键，当接收到用户对还原按键的按压操作时，还原按键会响应用户的按压操作产生还原信号；当未接收到用户对还原按键的按压操作时，还原按键则会产生非还原信号。其中，还原信号为低电平信号(例 如，0V)，非还原信号为高电平信号(例如，3.3V)。
可选的，在本实施例中，电子设备100还包括开机触发模块120，开机触发模块120与开机还原装置100A电连接。开机触发模块120配置成向开机还原装置100A提供开机信号，开机还原装置100A配置成依据开机信号进行开机操作。
在本实施例中，开机触发模块120可以包括开机按键，当接收到用户对开机按键的按压操作时，开机按键响应用户按压操作产生开机信号。当未接收到用户对开机按键的按压操作时，开机按键则会产生非开机信号。其中，开机信号为低电平信号(例如，0V)，非开机信号为高电平信号(例如，3.3V)。

可以理解，当用户未对还原触发模块130进行按压操作时，还原触发模块130无还原信号提供至电源提供模块170，电源提供模块170在未接收到还原信号时，不会产生工作电压，还原控制模块150在无工作电压的情况下，是不会进行还原操作，也不会向开机控制模块140产生开机处理信号，开机控制模块140则不会进行开机操作。因电源提供模块170无工作电压提供至还原控制模块150，当还原控制模块150不进行还原操作，处于待机状态时，不会消耗电能。
请参照图7，为图6所示的开机还原装置100A的一种可实施的电路原理图，电源提供模块170包括反相器U10和第一电源芯片U2，还原触发模块130通过反相器U10分别与第一电源芯片U2和还原控制模块150电连接，第一电源芯片U2还与还原控制模块150电连接。

可以理解，反相器U10将为低电平的还原信号Recovery进行反相处理得到为高电平的还原处理信号Recovery_ON_1，第一电源芯片U2获得为高电平的还原处理信号Recovery_ON_1后会产生工作电压EC_PWR。
若用户未触发还原按键，反相器U10将接收为高电平的非还原信号，反相器U10反相则会得到为低电平的非还原处理信号，第一电源芯片U2获得为电平的非还原处理信号则不会产生工作电压EC_PWR。
其中，反相器U10与第一电源芯片U2的使能端电连接，第一电源芯片U2的使能端在获得高电平信号时，第一电源芯片U2才会进行工作，进而产生工作电压EC_PWR。第一电源芯片U2配置成将电子设备100的***电压VSYS进行转换得到工作电压EC_PWR，第一电源芯片U2可以为DC-DC(直流转直流)转换芯片。

其中，控制器U5可以为嵌入式控制器(EmbedController，EC)，处理器U6可以为***芯片(System on Chip，SOC)。

可以理解，第一使能信号PHONE_ON_EC_2为高电平信号，开机控制模块140与第一电源芯片U2的使能端电连接。第一电源芯片U2的使能端在接收到为高电平的第一使能信号PHONE_ON_EC_2能够持续向控制器U5提供工作电压EC_PWR。即使用户停止按压还原按键，反相器U10向第一电源芯片U2提供为低电平的非还原处理信号，第一电源芯片U2也能向控制器U5提供工作电压EC_PWR，使得控制器U5能够完成还原操作。
可选的，如图8所示，电源提供模块170还包括延时芯片U3，反相器U10通过延时芯片U3分别与第一电源芯片U2和还原控制模块150电连接。延时芯片U3配置成对还原处理信号Recovery_ON_1进行延时处理得到延时后的还原处理信号Recovery_ON_2；第一电源芯片U2配置成依据延时后的还原处理信号Recovery_ON_2向还原控制模块150提供工作电压EC_PWR；还原控制模块150配置成在接收到工作电压EC_PWR的情况下，依据延时后的还原处理信号Recovery_ON_2进行还原操作，并依据延时后的还原处理信号Recovery_ON_2向开机控制模块140发送开机处理信号Boot_ON。
可以理解，延时芯片U3配置成对还原处理信号Recovery_ON_1进行延时处理，使得还原处理信号Recovery_ON_1持续一段时间，以保证控制器U5工作后，向第一电源芯片U2发送第二使能信号EC_ON_2之前，第一电源芯片U2的使能端能持续接收到高电平信号。延时芯片U3可以使得还原处理信号Recovery_ON_1持续向第一电源芯片U2发送500s。
