技术领域
本申请涉及智能设备领域，尤其涉及一种智能设备启动方法、装置、智能设备和可读存储介质。
背景技术
目前智能电视已经发展成为人们生活中不可或缺的娱乐、通讯设备，目前市场上尤其是海外市场对智能电视等设备是否支持快速待机功能，即设备的挂起到内存(STR-Suspend To Ram)功能有极大的需求，STR模式可在3秒内实现完全开机，极大的缩短开机时间，并且能比较完整的保持上一次用户使用的环境，用户体验较好。但是在长时间的STR待机过程中，系统各个模块有可能出现异常导致系统奔溃，系统奔溃之后会导致系统重启，这种异常的重启会对用户造成极大的困扰，影响用户体验，还有可能产生客诉。
例如，大部分国家强制要求智能设备需要支持快速待机功能，有大部分的客户反馈电视在待机之后概率性出现自动开机，开机时间不固定，可能是在白天、晚上或者出差旅游回来之后发现电视已开机，这种情况极大的影响用户的使用。

具体实施方式
下面将结合本申请实施例中附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
通常在此处附图中描述和示出的本申请实施例的组件可以以各种不同的配置来布置和设计。因此，以下对在附图中提供的本申请的实施例的详细描述并非旨在限制要求保护的本申请的范围，而是仅仅表示本申请的选定实施例。基于本申请的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。
在下文中，可在本申请的各种实施例中使用的术语“包括”、“具有”及其同源词仅意在表示特定特征、数字、步骤、操作、元件、组件或前述项的组合，并且不应被理解为首先排除一个或更多个其它特征、数字、步骤、操作、元件、组件或前述项的组合的存在或增加一个或更多个特征、数字、步骤、操作、元件、组件或前述项的组合的可能性。
此外，术语“第一”、“第二”、“第三”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
除非另有限定，否则在这里使用的所有术语(包括技术术语和科学术语)具有与本申请的各种实施例所属领域普通技术人员通常理解的含义相同的含义。所述术语(诸如在一般使用的词典中限定的术语)将被解释为具有与在相关技术领域中的语境含义相同的含义并且将不被解释为具有理想化的含义或过于正式的含义，除非在本申请的各种实施例中被清楚地限定。
高级配置和电源管理接口ACPI(Advanced Configuration and Power Management Interface)共有六种状态，分别是S0到S5，它们代表的含义分别是：S0-实际上这就是我们平常的工作状态，所有设备全开，功耗一般会超过80W；S1-也称为电源挂起POS(Power on Suspend)，这时除了通过CPU时钟控制器将CPU关闭之外，其他的部件仍然正常工作，这时的功耗一般在30W以下；(其实有些CPU降温软件就是利用这种工作原理)；S2-这时CPU处于停止运作状态，总线时钟也被关闭，但其余的设备仍然运转；S3-这就是挂起到内存STR(Suspend to RAM)，这时的功耗不超过10W；S4-也称为挂起到硬盘状态STD(Suspend to Disk)，这时系统主电源关闭，但是硬盘仍然带电并可以被唤醒；S5-这种状态是最干脆的，就是连电源在内的所有设备全部关闭，即关机(shutdown)，功耗为0。
最常用到的是S3状态，即挂起到内存STR(Suspend to RAM)模式。顾名思义，STR就是把系统进入STR前的工作状态数据都存放到内存中去。在STR状态下，电源仍然继续为内存等最必要的设备供电，以确保数据不丢失，而其他设备均处于关闭状态，系统的耗电量极低。一旦我们按下Power按钮(主机电源开关)，系统就被唤醒，马上从内存中读取数据并恢复到STR之前的工作状态。内存的读写速度极快，因此我们感到进入和离开STR状态所花费的时间不过是几秒钟而已；而S4状态，即挂起到硬盘STD(Suspend to Disk)与STR的原理是完全一样的，只不过数据是保存在硬盘中。由于硬盘的读写速度比内存要慢得多，因此用起来也就没有STR那么快了。
在一种可选的实施例中，参见图1，示出了一种智能设备启动方法包括以下步骤：
S100：当所述智能设备处于低功耗运行状态时，监测所述智能设备的各个功能模块。
智能设备一般包括4种低功耗运行状态，即高级配置和电源管理接口ACPI中所对应的S1到S4，S1-电源挂起POS(Power on Suspend)，这时除了通过CPU时钟控制器将CPU关闭之外，其他的部件仍然正常工作，这时的功耗一般在30W以下；S2-这时CPU处于停止运作状态，总线时钟也被关闭，但其余的设备仍然运转；S3-挂起到内存STR(Suspend to RAM)，这时的功耗不超过10W，STR就是把系统进入STR前的工作状态数据都存放到内 存中去，在STR状态下，电源仍然继续为内存等最必要的设备供电，以确保数据不丢失，而其他设备均处于关闭状态，系统的耗电量极低，一旦按下Power按钮(主机电源开关)，系统就被唤醒，马上从内存中读取数据并恢复到STR之前的工作状态，内存的读写速度极快，因此进入和离开STR状态所花费的时间不过是几秒钟而已；S4-挂起到硬盘状态STD(Suspend to Disk)，这时系统主电源关闭，但是硬盘仍然带电并可以被唤醒。
应当理解，对于处于低功耗运行状态的智能设备，内部的部分功能元件仍处于工作状态，监测所述智能设备的各个功能模块，有利于当某一功能单元出现异常时，及时处理异常信息。
示范性的，智能设备的系统进入STR待机之后会保持一定时间间隔的RTC(Real-Time Clock)唤醒，唤醒的时候用户界面并无显示，仅仅是为了完成一些后台定时工作，之后系统会继续进入STR待机状态。系统从STR到RTC唤醒再到进入STR的过程中，各类设备的驱动程序会依次执行Suspend->Resume->Suspend流程，即驱动线程挂起->驱动线程继续执行->驱动线程挂起。可以理解，各个驱动模块的供应商提供的驱动稳定性不一致，有可能导致在极长时间(7-30天)的STR之后概率性出现相关驱动模块的崩溃(Panic)，进而导致系统异常重启，这类异常启动的时间不固定，有可能是在白天，也有可能是在半夜。
因此，监测所述智能设备的各个驱动程序的驱动线程挂起和驱动线程继续执行是否异常，有利于及时发现驱动程序的异常问题，及时针对驱动程序的异常问题进行有效处理。
S200：在接收到系统启动指令时，确定是否监测到导致重启的功能模块异常。
智能设备对于接收到的系统启动指令，将根据是否监测到导致重启的功能模块异常判断接收到的系统启动指令是正常的启动指令，还是异常的启动指令。
示范性的，当监测到某一驱动模块异常时，向电源管理模块发送导致重启的异常信息。电源管理模块将确定是否接收到导致重启的异常信息，若接收到导致重启的异常信息，则确定监测到导致重启的功能模块异常。
S300：若未监测到导致重启的功能模块异常，则正常启动。
当智能设备接收到的系统启动指令，并且智能设备未监测到导致重启的功能模块异常，则智能设备正常启动。
S400：若监测到导致重启的功能模块异常，则在所述异常触发所述智能设备自动重启后恢复所述低功耗运行状态。
当智能设备接收到的系统启动指令，并且智能设备监测到导致重启的功能模块异常，则在异常触发所述智能设备自动重启后恢复所述低功耗运行状态。
应当理解，智能设备自动重启是后台系统自动重启，显示屏幕保持低功耗运行状态，避免显示屏幕由于异常触发智能设备自动重启时突然显示，影响用户的使用体验。
在一种可选的实施方式中，可以预先统计导致处于低功耗运行状态的智能设备的系统突然崩溃的异常信息，以对异常信息进行过滤，若是会导致智能设备异常启动的异常信息，则智能设备自动重启是后台系统自动重启，显示屏幕保持低功耗运行状态，后台系统通过自动重启修复完成后，智能设备恢复对应的低功耗运行状态。
在一种可选的实施例中，可以通过监测处于低功耗运行状态的智能设备的各个功能模块；在接收到系统启动指令时，确定是否监测到导致重启的功能模块异常；若未监测到导致重启的功能模块异常，则正常启动；若监测到导致重启的功能模块异常，则在所述异常触发所述智能设备自动重启后恢复所述低功耗运行状态。本申请实施例的技术方案解决智能设备因某一功能模块异常触发处于待机状态的设备突然启动的问题，使得处于待机的智能设备长期处于稳定的低功耗运行状态，保证智能设备低功耗运行状态的稳定性，有利于提高用户体验。
