具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
在一些实施例中，为了在终端设备出现故障无法联网时，让终端设备与云端服务器继续通信，同时对终端设备进行必要的维护，本公开实施例通过利用终端设备的SMS通信通道来实现终端设备无法联网时与云端服务器的继续通信，并通过SMS通道发送故障信息和维护指令，实现了故障终端设备的远程维护。
请参见图1，图1为本实施例提供的一种远程维护设备方法的基本流程示意图，远程维护设备方法包括如下步骤S101至S103。
在步骤S101，终端设备接收服务器下发的维护指令。
在本实施例中，服务器下发的维护指令包括但不限于SMS(Short Messaging Service)指令，SMS指令即是通过SMS短信的方式接收的维护指令。
在步骤S102，根据所述维护指令对所述终端设备进行维护，并更新终端设备的维护状态信息。
在步骤S103，将所述维护状态信息上报至所述服务器。
本实施例中，维护指令为类SMS指令，在步骤S101之后还可以包括：对接收到的SMS命令进行处理；获取接收到的SMS命令的命令格式；当为静默格式时，将SMS命令处理为静默SMS；判断静默SMS是否为SMS命令码；当为SMS命令码时，根据密钥对SMS命令进行解 析得到解析SMS命令。
可以理解的是，在实际应用中由于设备终端收到的SMS信息会包括多种类型和格式，因此终端设备在接收到SMS命令时需要先对SMS命令进行处理，通过处理结果来确定SMS命令的格式类型，并在SMS命令为静默SMS时判断SMS命令是否为SMS命令码，为命令码时才认为该SMS命令是维护指令或登记指令，并根据密钥解析SMS命令得到解析SMS命令，该解析SMS命令为终端设备可以读取的可用于终端设备进行维护或登记所使用命令码。
在本实施例中，为了保证终端设备和云端服务器之间传输的SMS命令的安全性，因此需要将传输的SMS命令进行加密之后再传输，同时为了保证终端设备和云端服务器实现SMS命令正确的传输，终端设备和云端服务器之间还需要有Token认证的过程。本实施例中，根据终端设备的固定信息生成加密Token信息，并将加密Token信息通过预设加密算法生成密钥，密钥为终端设备与服务器之间交互的验证信息。在本实施例中，将加密Token信息通过预设加密算法生成密钥的方式包括但不限于将加密Token信息通过不可逆MD5加密算法和/或AES-256加密算法生成密钥。可以理解的是，在本实施例中，该密钥在设备终端上和云端服务器中同时存在，并且设备终端上和云端服务器上存储的密钥相同。
在本实施例中，考虑到在一些情况下终端设备一次接收到的SMS命令可能是不完整的命令，因此，在根据密钥对SMS命令进行解析得到解析SMS命令之前还包括：判断解析SMS命令是否为级联SMS；当为级联SMS时生成级联SMS接收标识，并更新级联SMS接收标识，同时判断SMS接收标识是否接收完毕，在接收完毕后，将接收完毕的SMS命令统一组成一个整体的SMS。
在终端设备对接收到的SMS命令进行必要的处理得到解析SMS命令后，需要确定解析SMS命令为登记命令还是维护指令，因此，在根据密钥对SMS命令进行解析得到解析SMS命令之后还包括：获取解析SMS命令的命令码前缀；当命令码前缀为登记命令时，至少获取命令中的登记URL和SMS号码；当命令码前缀为维护参数设置命令时， 解析SMS命令为维护指令。
可以理解的是，当终端设备第一次开机，或者终端设备由一个云端服务器网络更换到其他的云端服务器网络上时，需要先在连接的云端服务器上进行认证登记，因此，当终端设备第一次连接到云端服务器上时，接收到的SMS命令有可能为登记命令，至少获取命令中的登记URL和SMS号码，来完成设备登记；当终端设备在完成登记后，收到的SMS命令通常就会是维护指令，或者监听指令。监听指令通常是服务器下发的询问指令，用于确定终端设备是否在网，以及确定终端设备的运行是否正常。
在终端设备需要进行登记时，本实施例提供一种登记的方法，包括但不限于：获取设备信息，并将设备信息按照预设格式进行组合；当终端设备可以联网时，通过登记URL向服务器发送包含设备信息和加密Token信息的登记请求；当终端设备不可以联网时，通过SMS号码向服务器发送包含设备信息和加密Token命令的SMS登记命令。
可以理解的是，当终端设备首次开机时，终端设备通常都能正常运行，因此在获取到服务器的登记URL和SMS号码后，会优先通过物联网方式通过登记URL向服务器发送包含设备信息和加密Token信息的登记请求，通过互联网方式发送设备信息和加密Token信息的登记请求还能进一步的检测终端设备的运行状况；当终端设备无法通过互联网方式发送设备信息和加密Token信息的登记请求时，可以通过SMS号码向服务器发送包含设备信息和加密Token命令的SMS登记命令的方式进行登记。
在终端设备向服务器发送登记请求或SMS登记命令之后还包括：确定是否接收到服务器下发的登记成功信息；当接收到登记成功信息时，终端设备将登记标记设置为1；当未接收到登记成功信息时，终端设备将登记标记设置为0，并按照预设周期重复向所述服务器发送登记请求或SMS登记命令。终端设备在完成设备登记后将设备登记的标记进行对应的改变可以缩短终端设备处理SMS命令的时间。
在终端设备完成登记认证后，并且在接收到的SMS指令为维护指令后进入步骤S102，步骤S102可以包括：根据维护指令中的设备 参数维护命令类型对命令进行分组；设备参数维护命令包括：wifi模块命令、网络模式命令、APN模块命令、恢复出厂设置命令中的至少一种。由于设备接收得到的维护维护指令包括但不限于wifi模块命令、网络模式命令、APN模块命令、恢复出厂设置命令中的至少一种参数维护命令，因此需要将维护指令中的设备参数维护命令根据命令类型进行分组，分组后可确定参数维护命令对应的维护策略。
本实施例给出了一种根据维护指令中的设备参数维护命令类型对命令进行分组的方法，包括：获取设备参数维护命令中的nv参数信息，并根据nv参数信息确定设备参数维护命令的类型。由于nv参数是对功能模块的工作参数进行直接设置的参数，并且也是维护信息必不可少的参数信息，因此通过确定nv参数信息可以十分方便的确定设备参数维护命令的类型。
在完成分组后，需要根据分组将分组中的nv参数信息更新到对应的功能模块中，来完成对应功能模块的参数更新，因此，根据维护指令对终端设备进行维护包括：将分组后的设备参数维护命令中的nv参数信息发送给对应的功能模块；对应的功能模块接收到nv参数信息后更新模块中的nv参数，并更新对应功能模块的维护状态信息。
可以理解的是，在得到更新后的维护状态信息后，终端设备向云端服务器上报更新后的维护状态信息，包括但不限于通过互联网上报或通过SMS命令进行上报。通过互联网上报更新后的维护状态信息的好处在于可以同时验证终端设备的联网故障是否恢复。
根据本公开实施例提供的远程维护设备方法，通过终端设备接收服务器下发的维护指令；根据维护指令对终端设备进行维护，并更新终端设备的维护状态信息；将维护状态信息上报至服务器。当维护指令为类SMS指令时，终端设备接收云端服务器发送的SMS命令，并通过SMS命令中的维护指令对终端设备进行维护，并向云端服务器上报更新后的维护状态信息，使得终端设备在出现故障导致终端设备无法连接到互联网时，可以利用SMS通道对终端设备进行维护，降低了终端设备维护的成本。
在本公开的另一些实施例中，当终端设备上出现故障时，终端 设备需要将故障信息发送给云端服务器，云端服务器根据故障信息生成对应的维修指令，并将维修指令下发到对应的终端设备来对终端设备进行维护。按照已有的方案，当终端设备出现故障导致终端设备无法连接到互联网上时，终端设备将无法上报故障信息，服务器也就无法下发对应的维护指令。本实施例提出一种远程下发设备维护指令方法，服务器接收SMS故障信息，并下发SMS维护指令，实现了故障终端设备的维护。
参见图2，图2为本实施例提供的一种远程下发设备维护指令方法的基本流程图，该远程下发设备维护指令方法包括如下步骤S201至S203。
在步骤S201，服务器接收终端设备上报的故障信息。
在本实施例中，服务器接收的故障信息包括但不限于SMS(Short Messaging Service)指令，SMS指令即是通过SMS短信的方式接收的故障信息。
在步骤S202，根据所述故障信息生成对应的维护信息，并对所述维护信息进行处理生成维护指令。
在步骤S203，将所述维护指令下发给所述终端设备。
在本实施例中，故障信息为类SMS指令，在步骤S201之前还包括：检测终端设备是否已经登记；当终端设备未登记时，生成云端服务器的登记URL和SMS号码，并通过SMS信息发送给终端设备。检测终端设备是否已经登记的方法包括：检测接收到的故障信息中的Token信息，并将Token信息与云端服务器上保存的Token信息进行比较；当没有匹配的Token信息时，该终端设备被为未登记设备，并向该终端设备发送至少包含云端服务器的登记URL和SMS号码的SMS命令；或者，当检测到接收的SMS指令为登记请求命令时，登记请求命令中包括但不限于终端设备的IMEI、IMSI、OEM至少一种信息，该终端设备为未登记设备，并将登记请求命令中的加密Token信息保存。
在服务器将登记URL和SMS号码通过SMS信息发送给终端设备之后还包括：检测是否收到终端设备发送的登记请求或SMS登记命令；接收到登记请求或SMS登记命令后，将登记请求或SMS登记命令中的 设备信息按照模块类型件分类，并保存登记请求中的加密Token信息或SMS登记命令中的加密Token命令。
在SMS传输的过程中，为了保证传输文件的安全性，需要对SMS命令进行加密，为了保证云端服务器和终端设备之间传输的SMS命令可以互相加密和解密，因此要求云端服务器上存储的密钥与终端设备上的密钥共享且相同，因此在第一次接收到终端发送的加密Token后需要对加密Token保存以用于两个设备之间的互相验证，同时云端服务器需要根据加密Token生成与终端设备对应的密钥，生成密钥所采用的加密算法与本公开的一些实施例中终端设备上生成密钥的加密算法相同。
在本实施例中，步骤S202可以包括：根据密钥和加密Token信息或加密Token命令生成加密SMS命令；将维护信息添加到加密SMS命令中，并设置加密SMS命令的命令格式为静默格式。由于发送给终端设备的维护指令为终端设备进行设备维护的SMS命令，该命令通常只需要在终端设备的后台运行即可，不需要在终端设备的前台进行提醒，因此，在加密SMS命令中添加维护信息后，需要将该加密SMS命令的命令格式设置为静默格式，使得加密SMS命令为静默SMS命令。
在本实施例中，在步骤S203之后还可以包括：检测在预设时间段内是否接收到终端设备上报的维护状态信息；未接收到维护状态信息时，向终端设备再次向发送维护指令，直至接收到维护状态信息；在接收到维护状态信息时，对维护状态信息进行解析确定是否维护成功，未维护成功时根据维护状态信息重新向终端设备发送第二维护指令。在云端服务器生成维护指令后将该维护指令下发给对应的终端设备，之后还需要接收终端设备上报的维护状态信息，以确定终端设备是否完成设备维护。云端服务器接收上报的维护状态信息的通道包括但不限于，互联网通道和SMS通道，在预设时间内未接收到维护状态信息时，需要重复发送维护指令；当接收到维护状态信息后，需要确定维护状态信息是否完成终端设备的维护，当未完成时，会根据上报的维护状态信息生成第二维护指令，并发送给终端设备。
在本实施例中，为了保证云端服务器对于终端设备的长期管理 和监听，云端服务器会按照预设周期向终端设备发送监听命令，以获取终端设备的运行状态和信息。
本实施例提供了一种远程下发设备维护指令方法，通过获取终端设备上报的故障信息，并对故障信息进行分析生成对应的维护指令，将生成的维护指令下发给对应的终端设备。当故障信息为类SMS指令时，下发的维护指令也为类SMS指令，从而达到了在无法与终端设备进行互联网通信的请况下，远程给终端设备下发维护指令的效果，实现了云端服务器对终端设备的远程维护。
本公开提供的另一些实施例中，本实施例提供了一种终端设备，参见图3。图3为本实施例提供的一种终端设备的结构示意图，该终端设备包括：接收模块31、维护模块32和上报模块33。
接收模块31用于接收服务器下发的维护指令。
维护模块32用于根据维护指令对终端设备进行维护，并更新终端设备的维护状态信息。
上报模块33用于将维护状态信息上报至服务器。
在本实施例中，维护指令为类SMS指令，接收模块31包括：SMS接收模块、密钥处理模块和命令解析模块。SMS接收模块用于接收SMS命令。密钥处理模块用于根据密钥对SMS命令进行解析得到解析SMS命令。命令解析模块用于获取SMS命令的命令格式，确定SMS命令是否为SMS命令码，以及获取解析SMS命令的命令码前缀。
在本实施例中，维护模块包括：设备信息收集模块和设备参数分发模块。设备信息收集模块用于收集终端设备的设备信息，设备信息包括终端设备所包含的各种功能模块和固定设备信息。设备参数分发模块用于根据维护指令中的nv参数信息对命令进行分组，并将分组后的nv参数信息分发到对应的功能模块中。
在本实施例中，上报模块33包括：网络交互模块、登记模块和发送模块。网络交互模块用于与其他设备进行网络交互。登记模块用于记录终端设备的登记信息。发送模块用于发送维护状态信息。

本实施例还提供了一种云端服务器，参见图4。图4为本实施例提供的一种云端服务器的结构示意图，云端服务器包括：服务器接收模块41、维护信息生成模块42和服务器发送模块43。服务器接收模块41用于接收终端设备上报的故障信息。维护信息生成模块42用于根据故障信息生成对应的维护信息，并对维护信息进行处理生成维护指令。服务器发送模块43用于将维护指令通过服务器信息下发给终端设备。
在本实施例中，故障信息为类SMS指令，服务器接收模块41为SMS接收模块，服务器发送模块43为SMS发送模块。SMS接收模块包括：认证设备模块和解析模块。认证模块用于对终端设备进行认证，确定终端设备是否登记。解析模块用于对接收到的故障信息采用密钥进行解析。

可以理解的是，本实施例提供的云端服务器除了上述的SMS接收模块41、维护信息生成模块42和SMS发送模块43还包括：处理器、存储器及通信总线。通信总线用于实现处理器、存储器、SMS接收模块41、维护信息生成模块42和SMS发送模块43之间的连接通信。处理器用于执行存储器中存储的一个或者多个计算机程序，以实现上述实施例中的远程维护设备方法中的至少一个步骤。
本实施例还提供了一种远程设备维护系统，参见图5。图5为本 实施例提供的一种远程设备维护系统的示意图，该远程设备维护系统包括：基站52、终端设备53和云端服务器51。终端设备53将故障信息以SMS命令发送给基站52，基站52将故障信息发送给云端服务器51；云端服务器51对故障信息进行处理得到维护信息，将维护信息以SMS命令发送给附基站52，基站52将维护信息发送给终端设备53；终端设备53根据维护信息进行设备维护，并将维护结果发送给基站52，基站将维护结果发送给云端服务器53。
