家庭服务系统的故障处理方法及家电设备、服务器 【技术领域】
本发明涉及智能家居的控制与管理技术领域，具体涉及一种家庭服务系统的故障处理方法及家电设备、服务器。
【背景技术】
家庭服务系统的主要功能是通过服务器对各种家电设备进行集中及异地监视、控制和事务性管理，保持家电设备与居住环境的和谐，其中服务器作为家庭服务系统的核心，如何保证其在发生故障时不影响整个家庭服务系统的正常运转显得尤为重要。
当前业界普遍采用主备切换机制以避免服务器在发生故障时造成整个家庭服务系统的瘫痪，即当检测到主服务器发生故障时切换为备用服务器。采用该机制的方案有两种：一是，主服务器将数据同步至备用服务器并向备用服务器请求主备切换，备用服务器在未发生故障时与家电设备建立连接；二是，主、备服务器同时向调度服务器发送请求，调度服务器接收到请求后从数据库获取发出请求的主、备用服务器的列表，然后调度服务器从页面服务器获取默认配置的主服务器的IP，决策采用主服务器或备用服务器进行连接。
上述方案一需要备用服务器频繁地对主服务器发送故障检测信息，会造成大量资源的浪费，并且如果主服务器完全不能工作，则无法向备用服务器发送请求切换命令，导致无法启用备用服务器。上述方案二需要增加调度服务器，会增加用户的购买成本，并且如果调度服务器发生故障，同样会造成整个家庭服务系统的瘫痪。
【发明内容】
本发明实施例提供一种家庭服务系统的故障处理方法及家电设备、服务器，以避免服务器发生故障时会造成家庭服务系统的瘫痪。
本发明采用的一个技术方案是：提供一种家庭服务系统的故障处理方法，所述家庭服务系统包括家电设备、控制连接家电设备的主服务器和备 用服务器，所述方法包括：家电设备向主服务器发送第一消息，当家电设备未接收到主服务器反馈的连接信号时，判定主服务器发生故障；家电设备根据预先存储的备用服务器的标识信息，向备用服务器发送第二消息，以使得备用服务器与家电设备建立连接。
其中，备用服务器与家电设备建立连接包括：备用服务器响应第二消息，并根据预先存储的家电设备的注册信息与家电设备建立连接。
其中，家电设备未接收到主服务器的反馈连接信号的步骤包括：在预定的第一时间阈值和/或预定的连接次数内家电设备未接收到主服务器反馈的连接信号。
其中，在主服务器未发生故障且与家电设备建立控制连接时，家电设备接收并存储由主服务器发送的备用服务器的标识信息；或者，在备用服务器首次安装且与家电设备建立连接后，家电设备接收并存储由备用服务器发送的备用服务器的标识信息。
其中，主服务器在排除故障时向家电设备和/或备用服务器发送告知信息，用以告知主服务器可正常工作；主服务器与家电设备建立连接。
其中，主服务器与家电设备建立连接的同时，所述方法包括：断开家电设备与备用服务器之间的连接；或者，继续保持家电设备与备用服务器之间的连接，若家电设备在预定的第二时间阈值内接收到主服务器和备用服务器分别发送的控制指令，则仅执行主服务器的控制指令，而舍弃备用服务器发送的控制指令。
其中，备用服务器根据第二消息及告知信息包含的识别码的类型进行状态切换，在识别码为第一类型识别码时，备用服务器切换至工作状态；在识别码为第二类型识别码时，备用服务器切换至空闲状态；在第二消息或告知信息未包括识别码时，备用服务器舍弃指令及告知信息。
本发明采用的另一个技术方案是：提供一种家电设备，由主服务器和备用服务器控制连接，所述家电设备包括：收发模块，用于向主服务器发送可用以建立连接的第一消息，以及接收备用服务器的标识信息；存储模块，用于存储备用服务器的标识信息；判断模块，用于在收发模块未接收到主服务器反馈的连接信号时，判定主服务器发生故障；以及处理模块，用于在判断模块判定主服务器发生故障时根据存储模块存储的备用服务器 的标识信息控制收发模块向备用服务器发送第二消息，以使得备用服务器与家电设备建立连接。
其中，家电设备还包括计时/计数模块，若在计时/计数模块计时的第一时间阈值和/或计数的连接次数内，收发模块未接收到主服务器反馈的连接信号，则判断模块判定主服务器发生故障。
其中，在判断模块判定主服务器未发生故障且与家电设备建立控制连接时，收发模块从主服务器接收备用服务器的标识信息；或者，在备用服务器首次安装且与家电设备建立连接后，收发模块从备用服务器接收备用服务器的标识信息。
其中，收发模块还用于接收主服务器在排除故障时发送的告知信息，处理模块根据告知信息控制家电设备与主服务器建立连接。
其中，家电设备还包括计时/计数模块，在主服务器与家电设备建立连接时，处理模块进一步用于控制家电设备断开与备用服务器的连接，或者，处理模块控制家电设备继续保持与备用服务器的连接，并且若收发模块在计时/计数模块计时的第二时间阈值内和/或计时/计数模块计数的连接次数内接收到主服务器和备用服务器分别发送的控制指令，则处理模块仅执行主服务器的控制指令，而舍弃备用服务器的控制指令。
其中，第二消息包含识别码，使得备用服务器根据识别码切换至工作状态。
本发明采用的又一个技术方案是：提供一种家庭服务系统的服务器，用于控制家庭服务系统的家电设备，所述服务器包括：存储模块，用于存储家电设备的注册信息；以及响应模块，用于响应家电设备发送的消息，并根据存储的家电设备的注册信息与家电设备建立连接。
其中，响应模块根据家电设备发送的消息中包含的识别码的类型进行状态切换，在识别码为第一类型识别码时，服务器切换至工作状态；在识别码为第二类型识别码时，服务器切换至空闲状态；在消息未包括识别码时，服务器舍弃消息。
通过上述技术方案，本发明实施例的家庭服务系统的故障处理方法及家电设备、服务器，无需主、备服务器之间进行信息交流，而仅由家电设备与备用服务器之间进行信息交流即可建立两者之间的连接，也无需额外 增加服务器，即可避免家庭服务系统的瘫痪，成本较低。

图3是本发明家庭服务系统的故障处理方法又一实施例的流程图；

【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，本发明以下所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
图1是本发明的家庭服务系统的故障处理方法一实施例的流程图，用以避免采用主备切换机制的家庭服务系统由于主服务器故障而发生瘫痪，所述家庭服务系统包括家电设备、主服务器及备用服务器，主服务器和备用服务器既可以是物理上分设的两个设备，也可以是同一设备的两种工作模式，且两者均可以基于家庭网络对家庭网络连接的一台或多台家电设备进行监视与控制。其中根据远程及近程需求，家庭网络至少包括基于远距离通信技术建立的网络，当然若仅满足近程需求，则家庭网络可以仅包括基于近场通信技术建立的网络。
如图1所示，本实施例的故障处理方法包括以下：
步骤S11：家电设备向主服务器发送第一消息，当家电设备未接收到主服务器反馈的连接信号时，判定主服务器发生故障。
家电设备向主服务器发送的第一消息相当于一种连接请求。
家电设备可以根据在预定的时间阈值内是否接收到主服务器的反馈连接信号，判断主服务器是否发生故障。具体地，若家电设备在预定的第一时间阈值内接收到主服务器反馈的与所述连接请求对应的信号，则表示主 服务器处于正常工作状态；若家电设备在预定的第一时间阈值内未接收到主服务器反馈的任何信号，或接收到其反馈的并非是与所述连接请求对应的信号，则表示主服务器已发生故障。
家电设备还可以根据在预定的连接次数内是否接收到主服务器的反馈连接信号，判断主服务器是否发生故障。具体地，若家电设备在预定的连接次数内接收到主服务器反馈的与连接请求对应的信号，则表示主服务器处于正常工作状态；若家电设备在预定的连接次数内未接收到主服务器反馈的任何信号，或接收到其反馈的并非是与所述连接请求对应的信号，则表示主服务器已发生故障。
家电设备还可以根据在预定的时间阈值及连接次数内是否接收到主服务器的反馈连接信号，判断主服务器是否发生故障。示例而言，家电设备初始化其计时器T＝0和计数器N＝0，而后向主服务器发送连接请求，同时计时器开始计时。若在发送连接请求之后的第一时间阈值Tmax1内接收到主服务器反馈的信号，则表示主服务器正常工作，并重置计时器T＝0和计数器N＝0以进行下一次故障检测。若在发送连接请求之后的第一时间阈值Tmax1内未接收到主服务器反馈的信号，可继续判断家电设备发送连接请求的次数N是否达到最大次数阈值Nmax(即N＝Nmax)，若N＜Nmax，则重复执行向主服务器发送连接请求的步骤直至N＝Nmax，并在N＝Nmax时，向备用服务器发送第二消息。
上述判断方式是根据家电设备自身与主服务器的连接情况判断主服务器是否发生故障，而不是现有技术中通过主服务器与备用服务器之间的相互检测发现，相比之下，可以减少备用服务器监听主服务器的频率，备用服务器仅在接收到家电设备的第二消息后开始工作，尤其是在备用服务器使用电池作为电源的情况下，能够大大降低备用服务器的电量消耗，延长备用服务器的电池的使用时间。
步骤S12：家电设备根据预先存储的备用服务器的标识信息，向备用服务器发送第二消息，以使得备用服务器与家电设备建立连接。
标识信息为表示备用服务器的身份信息的唯一标识。
并且，备用服务器与主服务器一样，均可以列表形式存储有家电设备的注册信息，包括ID(Identity，身份标识号码)、设备名称、调用方法以 及连接路径等，并且注册信息和所述标识信息均为家电设备与备用服务器或主服务器建立连接时需要的必要信息。
家电设备可以通过两种方式获取备用服务器的标识信息：
一是，主服务器在未发生故障且与家电设备建立控制连接时，主服务器与家电设备通信，主服务器不仅将自身的标识信息告知家电设备，而且将备用服务器的标识信息告知家电设备并由家电设备存储。
二是，在备用服务器首次安装且与家电设备建立连接后，家电设备在备用服务器上进行注册信息的登记，而后由备用服务器告知家电设备所述备用服务器的标识信息，此后备用服务器即切换为空闲状态。
家电设备存储备用服务器的标识信息(例如ID)为同时存储备用服务器与主服务器的标识信息，但仅使用备用服务器的标识信息。
备用服务器在接收到所述第二消息之后需要响应第二消息，从而根据预先存储的家电设备的注册信息与家电设备建立连接。其中，备用服务器可以根据第二消息(以及下文的告知信息)包含的识别码的类型进行启动(工作状态)与关闭(空闲状态)的切换，例如，在识别码为第一类型识别码1时，备用服务器切换至工作状态；在识别码为第二类型识别码0时，备用服务器切换至空闲状态；在接收到的第二消息未包含识别码时，备用服务器舍弃该第二消息，不进行切换。
基于上述，可知由家电设备与备用服务器之间进行信息交流即可建立两者之间的连接，无需主、备服务器之间进行信息交流，也无需额外增加服务器，即可避免家庭服务系统的瘫痪，成本较低。
另外，在整个家庭服务系统中，服务器(主服务器及备用服务器)与家电设备之间的通信不是每时每刻都在进行的，为了节省电能，服务器和家电设备会在约定的某个固定时间进行信息交互。为了让备用服务器获取与家电设备的约定时间，备用服务器可以与主服务器在每天的某个约定时间进行信息的同步，从而获得主服务器中存储的与家电设备进行通信的时间表，这样备用服务器在启动时即可知道何时应该与家电设备进行通信。如果主服务器在约定时间点之前发生故障，导致当天信息无法同步时，则备用服务器可以使用前一天的从主服务器同步得到的信息与家电设备约定进行信息交互的时间。
进一步，备用服务器接收到家电设备的启用命令(第二消息)之后，开始与家电设备建立连接，并且在主服务器故障恢复之前，备用服务器根据约定的时间与家电设备进行信息的交互。
图2是本发明家庭服务系统的故障处理方法另一实施例的流程图，适用于主服务器排除故障并恢复正常工作的情况。在图1所示步骤S12之后，如图2所示，本实施例的故障处理方法包括以下：
步骤S21：主服务器在排除故障时向家电设备和/或备用服务器发送告知信息，用以告知当前主服务器可正常工作。
步骤S22：断开家电设备与备用服务器之间的连接。
步骤S23：建立家电设备与主服务器之间的连接。
与图2所示不同的是，本发明实施例还可以在主服务器可正常工作时并不断开家电设备与备用服务器之间的连接，而是保持家电设备既与主服务器连接，又与备用服务器连接，如图3所示，包括：
步骤S31：主服务器在排除故障时向家电设备和/或备用服务器发送告知信息，用以告知当前主服务器可正常工作。
步骤S32：继续保持家电设备与备用服务器之间的连接，若家电设备在预定的第二时间阈值(并非上述判断主服务器是否发生故障时的第一时间阈值)内接收到主服务器和备用服务器分别发送的控制指令，则仅执行主服务器的控制指令，而舍弃备用服务器发送的控制指令；若家电设备在接收到备用服务器之后超过第二时间阈值接收到主服务器发送的控制指令，则执行备用服务器的控制指令。
本实施例可适用于主服务器与备用服务器隶属于不同物理设备，以及两者处于较远距离的使用场景，进一步改善使用体验。
图4是本发明的家电设备一实施例的原理框图。如图4所示，本实施例的家电设备40包括收发模块41、存储模块42、判断模块43以及处理模块44，其中：
收发模块41用于向主服务器61发送可用以建立连接的第一消息。
判断模块43用于在收发模块41未接收到主服务器反馈的连接信号时，判定主服务器61发生故障，具体地，判断模块43可以根据在预定的时间阈值和/或连接次数内是否接收到主服务器的反馈连接信号，判断主服务器 是否发生故障，例如若在家电设备40的计时/计数模块45计时的第一时间阈值和/或计数的连接次数内，收发模块41未接收到主服务器61反馈的连接信号，则判定主服务器61发生故障。
上述判断是否发生故障方式是根据家电设备40自身与主服务器61的连接情况实现的，而非现有技术中通过主服务器61与备用服务器62之间的相互检测发现，相比之下，可以减少备用服务器62监听主服务器61的频率，备用服务器62仅在接收到收发模块41所发送的第二消息后开始工作，尤其是在备用服务器62使用电池作为电源的情况下，能够降低备用服务器62的电量消耗，延长电池使用时间。
收发模块41进一步用于接收备用服务器62的标识信息，所述标识信息为表示备用服务器62的身份信息的唯一标识。收发模块41可以通过两种方式获取备用服务器62的标识信息：一是，在判断模块43判定主服务器61未发生故障且与家电设备40建立控制连接时，收发模块41从主服务器61接收备用服务器62的标识信息；二是，备用服务器62在启动后将备用服务器62的标识信息告知收发模块41，该种情况是在备用服务器62首次安装且与家电设备40建立连接后，家电设备40在备用服务器62上进行注册信息的登记，而后由备用服务器62告知家电设备40所述备用服务器62的标识信息，此后备用服务器62即切换为空闲状态。
采用第二种方式时，由备用服务器62直接告知家电设备40备用服务器的标识信息，并且备用服务器62中预先存储有家电设备40的注册信息，因此在切换为备用服务器62之后不必重新对家电设备40进行登记注册，能够大大减少两者之间的信息交互次数。
存储模块42用于存储备用服务器62的标识信息。
处理模块44用于根据判断模块43的判断结果决定是否需要向备用服务器62发送用以建立连接的第二消息，具体地，在判断模块43判定主服务器61发生故障时，处理模块44根据存储模块42存储的备用服务器62的标识信息控制收发模块41向备用服务器62发送第二消息，以使得备用服务器62与家电设备40建立连接。其中，所述第二消息包含识别码，备用服务器62根据识别码切换至工作状态。
再次参阅图4所示，在建立连接之后，收发模块41还用于接收主服务 器61在排除故障时发送的告知信息，处理模块44根据告知信息控制收发模块41建立家电设备40与主服务器61之间的连接。
并且，在建立家电设备40与主服务器61之间的连接的同时，处理模块44控制收发模块41断开家电设备40与备用服务器62的连接，或者，继续保持家电设备40与备用服务器62的连接，并且若收发模块41在计时/计数模块45计时得到的第二时间阈值(并非上述判断主服务器61是否发生故障时的第一时间阈值)内接收到主服务器61和备用服务器62分别发送的控制指令，则处理模块44仅执行主服务器61的控制指令，而舍弃备用服务器62的控制指令。
图5是本发明的服务器一实施例的原理框图。如图5所示，所述服务器50用于控制家庭服务系统的家电设备40，所述服务器50包括存储模块51以及响应模块52，其中：
存储模块51用于存储家电设备的注册信息。
响应模块52用于响应所述家电设备发送的消息，并根据存储的家电设备的注册信息与家电设备建立连接。
具体地，响应模块52根据家电设备发送的消息中包含的识别码的类型进行状态切换，例如，在识别码为第一类型识别码时，服务器50切换至工作状态；在识别码为第二类型识别码时，服务器50切换至空闲状态；在消息未包括识别码时，服务器50舍弃所述消息。
本发明实施例进一步提供一种家庭服务系统，所述家庭服务系统包括上述家电设备40以及可与家电设备40建立控制连接的服务器50。
本发明实施例的家电设备40、服务器50(主服务器61和备用服务器62)以及家庭服务系统的各个模块可以对应执行图1-图3所示实施例的故障处理方法，因此具有与其相同的有益效果。
应该理解到，以上所描述的家电设备40、服务器50以及家庭服务系统的实施方式仅仅是示意性的，所描述模块的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个模块可以结合或者可以集成到另一个系统中，或一些特征可以忽略，或不执行。各模块相互之间的连接可以是通过接口，也可以是电性或其它形式。
上述各功能模块作为家电设备40、服务器50以及家庭服务系统的组成 部分，可以是也可以不是物理框，既可以位于一个地方，也可以分布到多个网络单元上，既可以采用硬件的形式实现，也可以采用软件功能框的形式实现。本领域技术人员可以根据实际的需要选择其中的部分或者全部模块来实现本发明方案的目的。
再次说明，以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
