Description

一种控制方法及终端、计算机存储介质 技术领域

此外，根据所述第一路触发信号和所述第一检测信号，生成第二控制信号；所述第二控制信号用于维持断路开关的状态保持不变，进而维持电源电路的状态保持不变(即闭合状态)。
本发明实施例中，处理模块接收到第一路触发信号后，首先对第一路触发信号进行脉冲信号调整，得到固定宽度的脉冲信号。相应地，当检测模块检测到所述使能信号或数字信号时，生成固定宽度的脉冲信号作为第一检测信号。然后，处理模块对两路固定宽度的脉冲信号进行处理，处理结果为生成第二控制信号；或者，当检测模块未检测到所述使能信号或数 字信号时，生成低电频信号作为第二检测信号，处理模块对第一路触发信号和第二检测信号进行处理，处理结果为生成第一控制信号。
步骤105：根据所述控制信号，控制断路开关对电源电路进行开关操作，以通过所述电源电路断开闭合控制电源管理芯片重启。
本发明实施例中，断路开关根据处理模块输出的控制信号确定是否对电源电路进行相应的开关操作。
图2为本发明实施例二的终端的结构组成示意图，如图2所示，所述终端包括：
电源21：终端电源；
断路开关22：用于对电源输出的开关动作；
电源管理芯片23：输出调节后的电源给各模块电路；
处理器24：用于功能模块的控制管理；
功能模块25，包括显示模块、摄像模组、喇叭功放、震动电路等等；
检测模块26：检测处理器输出的使能信号或数字信号；
触发装置27：包括电源键、音量键、拍照键以及指纹识别模块等，用于产生触发信号，并触发处理器输出使能信号或数字信号给相应的功能模块；
处理模块28：用于对触发装置产生的触发信号及检测模块输出信号进行处理。
通过本发明实施例的上述终端实现本发明实施例的控制方法时，各个模块具有如下功能：
所述触发装置27，配置为获得触发操作，生成触发信号；将所述触发信号分为第一路触发信号和第二路触发信号；将所述第一路触发信号发送至所述处理模块28；将所述第二路触发信号发送至所述处理器24，以触发所述处理器24生成使能信号或数字信号；
所述处理器24，配置为在所述第二路触发信号的触发下生成使能信号或数字信号；
所述检测模块26，配置为检测所述使能信号或数字信号，并根据检测结果生成相应的检测信号；
所述处理模块28，配置为根据所述第一路触发信号以及所述检测信号，生成用于控制断路开关22的控制信号；
所述断路开关22，配置为根据所述控制信号，对电源电路进行开关操作，以通过所述电源电路断开闭合控制电源管理芯片23重启。
当所述处理器24在所述第二路触发信号的触发下生成所述使能信号或数字信号时，终端的状态为非死机状态；当所述处理器24在所述第二路触发信号的触发下不生成所述使能信号或数字信号时，终端的状态为死机状态。
所述检测模块26，还配置为判断是否检测到所述使能信号或数字信号；当检测到所述使能信号或数字信号，生成第一检测信号；当未检测到所述使能信号或数字信号，生成第二检测信号。
所述检测模块26，还配置为当检测到所述使能信号或数字信号，生成固定宽度脉冲信号；当未检测到所述使能信号或数字信号，生成低电平信号。
所述处理模块28，还配置为根据所述第一路触发信号和所述第二检测信号，生成第一控制信号；所述第一控制信号用于控制断路开关22对电源电路进行开关操作，以通过所述电源电路断开闭合控制电源管理芯片23重启。
终端中上述各个模块的工作顺序为：首先，触发装置27产生触发信号，触发信号分成两路，其中一路为：触发信号—>电源管理芯片23/处理器24(输出使能信号)—>检测模块26(检测使能信号输出检测信号)—>处理 模块28；另一路为：触发信号—>处理模块28；其次，处理模块28获取两路信号(检测模块26输出的检测信号和触发信号)，处理后输出控制信号控制断路开关22是否执行开关操作。
图3为本发明实施例三的控制方法的流程图，如图3所示，所述流程包括：触发装置触发后输出一脉冲信号，一路传给处理模块进行脉冲信号调整，输出一固定宽度的脉冲信号；另一路触发处理器输出使能信号，处理器输出的使能信号由检测模块进行检测，根据使能信号的有无分别输出不同检测结果给处理模块，如果检测模块检测到使能信号，则输出相应检测结果信号(如一固定宽度的脉冲信号)给处理模块，处理模块根据检测模块输出的检测信号和触发装置输出的脉冲信号进行处理，不输出控制信号给断路开关，则断路开关维持原状态；若检测模块未能检测到使能信号，则无相应检测信号输出，处理模块未获取到检测模块输出的检测信号，则对来自触发装置输出的脉冲信号进行处理后输出控制信号驱动断路开关动作，使电源输出通路瞬间断开闭合引起管理芯片掉电重启。
下面进一步以实施例来说明死机重启的过程，触发装置以电源键为例，检测模块检测信号以处理器输出的使能信号为例。
检测模的框图见图4，检测模块主要包含上升沿触发电路、下降沿触发电路、加法器电路及脉冲调整电路。上升沿触发电路用于输入电压由低电平变化为高电平时产生一正向脉冲信号，输入电压无变化时无输出；下降沿触发电路用于输入电压由高电平变化为低电平时产生一正向脉冲信号，输入电压无变化时无输出；加法器电路用于两路触发电路输出的加法运算；脉冲调整电路用于脉冲宽度的调整，输出固定宽度的脉冲信号。
处理模块主要包含延时电路及开关电路，其电路框图见图5，脉冲调整电路用于脉冲宽度的调整，输出固定宽度的脉冲信号；脉冲延时电路用于将输入脉冲信号延后一段时间；开关电路根据检测模块输出信号进行输入 输出信号的通断处理，检测模块输出低电平信号时，开关电路导通，检测模块输出高电平时，开关电路不导通。
本发明实施例死机检测信号过程，如图6：电源键触发一负向脉冲，一路送至处理模块，经脉冲调整电路后输出一宽度为t0的负向脉冲，再经脉冲延时电路，将脉冲信号延后一段时间t1(t1为设计允许按键触发后处理器输出使能信号最迟时间)传给开关电路；另一路经电源管理芯片，由处理器输出使能信号给相应的功能模块，如显示模块等；处理器输出的使能信号存在高低电平跳变，使能信号输入检测模块后分两路经上升沿和下降沿触发电路，再经加法器电路叠加输出，这样使能信号不管是由低电平跳变高电平或者高电平跳变低电平，都能实现一正向脉冲输出，再经脉冲调整电路输出一宽度为(t0+t1)的正向脉冲传至处理模块内部开关电路，作为开关电路的驱动信号；开关电路输入高电平驱动信号时，开关电路关闭，开关电路输入低电平驱动信号时，开关电路导通；按键触发后，检测模块和处理模块内部电路脉冲时序见图6；当按键触发后，若处理器正常工作输出使能信号，则经检测模块后输出宽度为(t0+t1)的正向脉冲使处理模块内的开关电路关闭，按键触发信号无法通过开关电路传至断路开关；若按键触发后，处理器死机异常未能及时输出使能信号，则检测模块无法输出高电平脉冲信号给处理模块内的开关电路，开关电路处于导通状态，按键触发信号经处理模块输出负向脉冲信号经开关电路传至断路开关，驱动断路开关对电源输出进行瞬间断开闭合操作，则电源管理芯片将因瞬间掉电而重启。
检测模块、处理模块内各个电路等均为电子电路，断路开关可以是电磁开关也可以是电子电路开关，这里不做详细说明。
上述死机检测重启过程只是本发明的一种实施例，并非限制本发明的专利范围，凡是利用检测装置对触发信号及相应处理器输出信号进行检测 从而控制电源输出开关，均同理包括在本发明权利保护范围之内。
用户在使用智能终端时，每次按电源键，会对终端进行待机或者唤醒操作，按电源键时会产生一触发信号，这个触发信号一边通过处理模块进行调整，另一边则触发处理器输出使能信号给显示模块，检测模块通过检测有无使能信号相应的输出不同检测信号给处理模块，处理模块对触发信号和检测信号进行处理判断，如果终端工作正常，则处理模块不输出控制信号给断路开关动作，如果终端工作出现死机异常，则处理模块输出控制信号给断路开关动作，终端会出现掉电自动重启；实现的效果是，终端正常使用时，按键功能正常使用，不会触发终端重启；终端使用过程中出现死机异常，则用户按键将出现终端自动重启。无需用户自行判断终端是否死机，是否需要拆装电池或者操作其他复位装置来进行终端重启作业。
