Description

设备批量升级方法及系统 技术领域
本申请涉及但不限于网络技术领域，尤其涉及一种设备批量升级方法及系统。
背景技术
随着移动互联网及智能家居等的兴起，在很大程度上推动了嵌入式领域的发展。一方面嵌入式设备在出厂前通常需要进行升级，该升级包含对嵌入式设备的固件升级、配置升级等；另一方面，嵌入式设备在返厂维修时，也需要进行版本升级等相关操作。对于单台嵌入式设备的升级来说，顺序操作成本很高，严重影响工作效率，因此，针对如此众多的嵌入式设备，批量操作的实现显得很重要。
嵌入式设备的一个典型特征就是设备的IP(Internet Protocol，网络互联协议)地址是固定的，无法在局域网内直接访问。传统的批量升级方法都是基于对IP地址的修改实现的，该方法需要升级客户端发送组播报文以搜寻嵌入式设备，当嵌入式设备接收到组播报文时，依据一定的算法对嵌入式设备的IP地址进行更改，然后反馈给升级客户端，由升级客户端针对特定的IP地址发起连接操作等。由于传统的方法需要修改嵌入式设备的IP地址，增加了升级客户端和嵌入式设备之间的交互流程，操作复杂，工作效率较低。

本发明的较佳实施方式
下面结合附图对本发明的实施方式进行描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。
本发明实施例提供了一种设备批量升级方法，可用于进行嵌入式设备的 批量升级，可通过包括升级客户端、主机、交换机及待升级的嵌入式设备的设备批量升级系统来实现，如图1所示为设备批量升级的环境部署结构示意图。其中，升级客户端可为运行于PC机(Personal Computer，个人计算机)上的工具软件，设置为：控制嵌入式设备升级，包含对升级文件的版本选择、启动、停止等操作。主机可为安装有Linux的双网卡主机，一侧的以太网口可连接PC机，另一侧的以太网口可连接交换机，同时，可在主机上针对每一台待升级的嵌入式设备创建一个虚拟网口。交换机可设置为：通过VLAN(Virtual Local Area Network，虚拟局域网)隔离报文，交换机下挂的每个待升级的嵌入式设备可以都附属于不同VLAN，每个VLAN都有各自唯一的VLAN标识。嵌入式设备可设置为：接收升级客户端命令、下载升级文件的固件版本、固件升级等。
可选地，如图2所示，为设备批量升级的内部模块关系结构示意图，大致地展示了相关模块之间的关系。其中，主机安装有双网卡，一侧以太网口eth1连接安装有升级客户端的PC机的NIC(Network Interface Card，网络适配器)，另一侧以太网口eth0连接交换机的中继(trunk)接口。eth0.x是vconfig命令基于以太网口eth0创建出的多个VLAN虚拟网口，x表示VLAN标识，每个虚拟网口对应到一个待升级的嵌入式设备。交换机配置多个VLAN，VLAN标识和eth0.x中的数字x相对应，每个VLAN连接一个待升级的CPE设备(即嵌入式设备)。
如图3所示，本发明实施例还提供了一种设备批量升级方法。该设备批量升级方法可用于进行嵌入式设备的批量升级。该设备批量升级方法包括：
步骤S10、交换机划分不同的VLAN连接嵌入式设备；
步骤S20、主机创建多个虚拟网口及创建桥后，设置不同虚拟网口的不同VLAN标识与交换机上所划分不同VLAN的标识匹配，并将所述多个虚拟网口与连接升级客户端的以太网口加入到桥中；
本实施例中，在对待升级的嵌入式设备进行批量升级之前需要完成升级系统的配置，可在交换机上划分不同的VLAN，每个VLAN都有自身唯一的标识，每个待升级的嵌入式设备从属于一个VLAN，即VLAN可与嵌入式设备进行一一对应连接。可在主机上创建多个虚拟网口，并且将虚拟网口与连 接到交换机一侧的以太网口绑定，每个虚拟网口也都可以有自身唯一的VLAN标识，该主机可为Linux主机。在配置的过程中，不同虚拟网口的VLAN标识可与交换机上划分不同VLAN的标识匹配，例如，虚拟网口eth0.x中的数字x可与交换机上的VLAN标识vlan x中的x相对应。主机上的所有网口可配置不同的IP地址，以及可包含所有的虚拟网口和两个实际的物理以太网口。由于建桥的需要，主机的IP地址可与嵌入式设备保持在同一网段。然后可在主机中创建桥，将虚拟网口和连接升级客户端PC的一侧以太网口加入到桥中，以通过桥形成通路来进行报文的转发。
在主机中桥和虚拟网口的创建可以如下所示：
brctl addbr br1
brctl addif br1 eth1
vconfig add eth0 2
brctl addif br1 eth0.2
其中，可通过brctl命令创建桥，并基于eth0建立一个eth0.2的虚拟网口，这样VLAN标识为2的报文可被eth0转交给虚拟网口eth0.2。同时，eth0.2和eth1可下挂在br1桥的下面，可使虚拟网口和升级客户端所在的PC机之间网络互通。
另外，可在主机上创建报文的NAT(Network Address Translation，网络地址转换)映射规则，该NAT映射规则可设置为：在将报文从升级客户端发送到嵌入式设备的过程中，需要将报文中携带的目标地址(即虚拟网口的IP地址)修改为嵌入式设备的IP地址，反之，在将报文从嵌入式设备返回到升级客户端的过程中，需要将报文中携带的嵌入式设备的IP地址修改为目标地址。
该报文可包括IP报文或ARP(Address Resolution Protocol，地址解析协议)报文，以下将以发送IP报文或ARP报文为例进行详细说明：
IP报文的网络地址转换映射规则可以如下：
ebtables-t broute-A BROUTING-p IPv4--ip-destination 192.168.1.2-j ipnat--to-ip-dst 192.168.1.1--ipnat-target CONTINUE
在将IP报文从升级客户端发送到嵌入式设备的过程中，将目标地址是192.168.1.2的虚拟网口地址修改为嵌入式设备地址192.168.1.1。
ebtables-t broute-A BROUTING-i eth0.2-p IPv4-j ipnat--to-ip-src 192.168.1.2--ipnat-target CONTINUE
在将IP报文从嵌入式设备返回至升级客户端的过程中，将入口是eth0.2的源地址修改为目标地址192.168.1.2。
ARP报文的网络地址转换映射规则可以如下：
arptables-A FORWARD-t filter-d 192.168.1.2-j mangle--mangle-ip-d 192.168.1.1
在将ARP报文从升级客户端发送到嵌入式设备的过程中，将目标地址是192.168.1.2的虚拟网口地址修改为嵌入式设备地址192.168.1.1。
arptables-A FORWARD-t filter-i eth0.2-s 192.168.1.1-j mangle--mangle-ip-s 192.168.1.2
在将ARP报文从嵌入式设备返回至升级客户端的过程中，将入口是eth0.2的IP源地址修改为目标地址192.168.1.2。
步骤S30、升级客户端将携带目标地址的报文发送至主机上与所述目标地址对应的虚拟网口；
本实施例中，升级客户端可为运行于PC机上的升级工具软件，用户可通过操作PC机指定目标地址，此时的目标地址为主机上虚拟网口的IP地址，并可由升级客户端将携带目标地址的报文发送至在主机上与目标地址对应的虚拟网口。该报文还可包括端口号、升级文件的版本号、升级客户端上用于下载升级文件的服务器的用户名及密码等，该服务器可为FTP(File Transfer Protocol，文件传输协议)服务器。由于升级客户端的网口通过网线与主机的以太网口eth1连接，而主机通过创建桥将以太网口eth1与所创建的虚拟网口连通，因此升级客户端在完成目标地址的设置后，可将报文发送至在主机上对应的虚拟网口。
可选地，为了进一步提高报文的传送效率，上述步骤S30之前，该设备批量升级方法可包括：
主机给需要接收的报文添加记号mark标记，以使所述主机的虚拟网口仅接收存在mark标记的报文。
可在主机上对从升级客户端发送过来的大量报文中，给需要接收的报文添加上mark标记，以保证在主机上的虚拟网口只能收到制定有mark标记的报文。使得对流经虚拟网口的报文添加标记，方便后面进行过滤以丢弃与虚拟网口无关的报文，减少了对垃圾报文的接收，大大提高了效率。
对报文添加mark标记可以如下所示：
ebtables-t broute-A BROUTING-p IPv4--ip-destination 192.168.1.2-j mark--set-mark 2--mark-target CONTINUE
ebtables-t broute-A BROUTING-p ARP--arp-ip-dst 192.168.1.2-j mark--set-mark 2--mark-target CONTINUE
对mark标记报文的控制可以如下所示：
ebtables-A FORWARD-o eth0.2--mark！2-j DROP
虚拟网口eth0.2仅处理mark标记为2的报文。
步骤S40、主机将所述目标地址修改为嵌入式设备的IP地址，并将所述虚拟网口对应的VLAN标识添加至所述报文；
可在主机的NAT上将目标地址修改为嵌入式设备的IP地址，以便嵌入式设备在接收到报文后，可对报文中携带的目标地址进行校验。主机可在报文中添加虚拟网口的VLAN标识，以便主机根据VLAN标识将报文转发至交换机上对应的VLAN。
步骤S50、主机根据所述VLAN标识将所述报文通过交换机上与所述VLAN标识对应的VLAN，转发至与所述VLAN连接的嵌入式设备；
由于主机上所建立的虚拟网口可与以太网口eth0连接，而该以太网口eth0又可通过网线与交换机的trunk接口连接，同时在交换机可划分有不同的VLAN，每个VLAN可通过网络与待升级的嵌入式设备连接，主机上不同虚拟网口的VLAN标识可与交换机上划分不同的VLAN标识匹配。因此，当报文到达主机后，主机可根据虚拟网口的VLAN标识将报文发送至在交换机上与VLAN标识对应的VLAN，再由交换机通过VLAN将报文发送至与其连接 的嵌入式设备。
步骤S60、嵌入式设备校验所述目标地址正确后反馈消息至升级客户端，并从升级客户端下载升级文件进行升级。
嵌入式设备可在接收到报文后，对目标地址进行校验。由于在上述已将目标地址修改为嵌入式设备的IP地址，因此嵌入式设备可判断目标地址是否与自身的IP地址一致，若一致则验证通过，并可反馈消息至升级客户端，然后可下载升级文件进行升级。
可选地，上述步骤S60可包括：嵌入式设备将携带源IP地址的消息通过与其连接的交换机对应的VLAN，发送至在与所述VLAN的标识匹配的主机上对应的虚拟网口，以使主机将所述源IP地址修改为虚拟网口的IP地址后转发至升级客户端，供升级客户端根据所述虚拟网口的IP地址发送携带升级文件版本的升级指令至嵌入式设备；
嵌入式设备在接收到所述升级指令后，通过升级客户端的下载服务器下载在所述升级指令中携带的对应版本的升级文件进行升级。
嵌入式设备可将携带源IP地址的消息发送至与其连接的交换机上的VLAN，此时，该源IP地址可为嵌入式设备的IP地址。然后可根据交换机所划分的VLAN与主机上创建多个虚拟网口的对应关系，通过交换机上VLAN的标识将消息发送至在主机上对应的虚拟网口。可在主机上将消息中的源IP地址修改为虚拟网口的IP地址，然后将消息发送至升级客户端。升级客户端可在接收到嵌入式设备反馈的消息后，根据消息中的虚拟网口的IP地址确定是哪个嵌入式设备反馈的消息。升级客户端可根据反馈的消息发送升级指令至对应的嵌入式设备，该升级指令可包括升级文件版本及名称。嵌入式设备在接收到升级指令后，可从上述升级客户端发送过来的报文中提取升级文件的版本号、FTP服务器的用户名及密码等消息，然后，可通过升级客户端的FTP服务器下载相应版本的升级文件，然后可对下载的升级文件进行校验，若是所需版本的升级文件，则可烧写快闪(FLASH)进行升级。若目标地址验证不通过，则嵌入式设备可丢弃该报文。
可选地，在嵌入式设备完成升级后，嵌入式设备将升级结果返回升级客户端。
如果升级成功，则嵌入式设备可回送升级成功的消息至升级客户端；如果升级失败，则嵌入式设备可回送升级失败的消息至升级客户端。升级客户端在接收到升级结果后，可以是通过对话框的形式显示“升级成功”或者“升级失败”的消息，也可以是通过语音播报的消息进行播报，或者是通过发短信或者邮件通知用户，也可以是通过其他的形式通知用户。从而使得嵌入式设备出厂时，可通过本设备批量升级方法由生产线对设备进行批量升级等操作，从而提升工作效率，减低人力成本。或者在嵌入式设备返修时，可通过本设备批量升级方法由返修中心对设备进行批量升级等操作，从而提升工作效率。
通过本发明实施例，在交换机上划分不同的VLAN连接嵌入式设备，在主机上创建多个虚拟网口及创建桥后，设置不同虚拟网口的不同VLAN标识与交换机上所划分不同VLAN的标识匹配，并将多个虚拟网口与连接升级客户端的以太网口加入到桥中，以使交换机、主机及嵌入式设备之间形成连接通路。升级客户端将携带目标地址的报文发送至主机上对应的虚拟网口后，主机将目标地址修改为嵌入式设备的IP地址，并根据虚拟网口的VLAN标识将报文通过交换机上与VLAN标识对应的VLAN转发至与该VLAN连接的嵌入式设备。嵌入式设备校验目标地址正确后反馈消息至升级客户端，并从升级客户端下载升级文件进行升级。实现了通过对主机划分虚拟网口及对交换机划分VLAN等操作，使得升级环境一次配置，多次使用，通过NAT映射、VLAN隔离等技术实现对设备的访问。在对嵌入式设备进行批量升级时无需修改嵌入式设备的IP地址，减少升级客户端和嵌入式设备之间的交互流程，操作简单明了，提高了对嵌入式设备批量升级的效率。
对应地，如图4所示，本发明实施例还提供了一种设备批量升级系统。该该设备批量升级系统可用于进行嵌入式设备的批量升级。该设备批量升级系统包括交换机10、主机20、升级客户端30及嵌入式设备40，其中，
交换机10，设置为：划分不同的VLAN来连接嵌入式设备40；
主机20，设置为：创建多个虚拟网口及创建桥后，设置不同虚拟网口的不同VLAN标识与交换机10上所划分不同VLAN的标识匹配，并将所述多个虚拟网口与连接升级客户端30的以太网口加入到桥中；
本实施例中，在对待升级的嵌入式设备40进行批量升级之前需要完成升 级系统的配置，可在交换机10上划分不同的VLAN，每个VLAN都有自身唯一的标识，每个待升级的嵌入式设备40从属于一个VLAN，即VLAN与嵌入式设备40进行一一对应连接。在主机20上创建多个虚拟网口，并且将虚拟网口与连接到交换机10一侧的以太网口绑定，每个虚拟网口也都有自身唯一的VLAN标识，该主机20可为Linux主机。在配置的过程中，不同虚拟网口的VLAN标识要和交换机10上划分不同VLAN的标识匹配，例如，虚拟网口eth0.x中的数字x与交换机10上的VLAN标识vlan x中的x相对应。主机20上的所有网口配置不同的IP地址，包含所有的虚拟网口和两个实际的物理以太网口。由于建桥的需要，主机的IP地址要和嵌入式设备保持在同一网段。然后在主机中创建桥，将虚拟网口和连接升级客户端PC的一侧以太网口加入到桥中，以通过桥形成通路进行报文的转发。
在主机中桥和虚拟网口的创建如下所示：
brctl addbr br1
brctl addif br1 eth1
vconfig add eth0 2
brctl addif br1 eth0.2
其中，通过brctl命令创建桥，并基于eth0建立一个eth0.2的虚拟网口，这样VLAN标识为2的报文会被eth0转交给eth0.2口。同时，eth0.2和eth1下挂br1桥下面，可使虚拟网口和升级客户端所在的PC机之间网络互通。
另外，在主机20上创建报文的网络地址转换映射(即NAT映射)规则，该NAT映射规则可设置为将报文从升级客户端30发送到嵌入式设备40的过程中，需要将报文中携带的目标地址(即虚拟网口的IP地址)替换为嵌入式设备40的IP地址，反之，将报文从嵌入式设备40返回到升级客户端30，需要将报文中携带的嵌入式设备40的IP地址修改为目标地址。
该报文可包括IP(Internet Protocol，网络互联协议)报文或ARP(Address Resolution Protocol，地址解析协议)报文，以下将以发送IP报文或ARP报文为例进行详细说明：
IP报文的网络地址转换映射规则：
ebtables-t broute-A BROUTING-p IPv4--ip-destination 192.168.1.2-j ipnat--to-ip-dst 192.168.1.1--ipnat-target CONTINUE
将IP报文从升级客户端30发送到嵌入式设备40的过程中，目标地址是192.168.1.2的虚拟网口地址修改为嵌入式设备40的地址192.168.1.1。
ebtables-t broute-A BROUTING-i eth0.2-p IPv4-j ipnat--to-ip-src 192.168.1.2--ipnat-target CONTINUE
将IP报文从嵌入式设备40返回至升级客户端，将入口是eth0.2的源地址改为目标地址192.168.1.2。
ARP报文的网络地址转换映射规则：
arptables-A FORWARD-t filter-d 192.168.1.2-j mangle--mangle-ip-d 192.168.1.1
将ARP报文从升级客户端30发送到嵌入式设备40的过程中，目标地址是192.168.1.2的虚拟网口地址修改为嵌入式设备的40地址192.168.1.1。
arptables-A FORWARD-t filter-i eth0.2-s 192.168.1.1-j mangle--mangle-ip-s 192.168.1.2
将ARP报文从嵌入式设备40返回至升级客户端30，将入口是eth0.2的IP源地址改为目标地址192.168.1.2。
升级客户端30，设置为：将携带目标地址的报文发送至主机20上与所述目标地址对应的虚拟网口；
本实施例中，升级客户端30为运行于PC机上的升级工具软件，用户可通过操作PC机指定目标地址，此时的目标地址为主机20上虚拟网口的IP地址，并由升级客户端30将携带目标地址的报文发送至主机上与目标地址对应的虚拟网口。该报文还包括端口号、升级文件的版本号、升级客户端上用于下载升级文件的服务器用的户名及密码等，该服务器可为FTP(File Transfer Protocol，文件传输协议)服务器。由于升级客户端30的网口通过网线与主机20的eth1以太网口连接，而主机20通过创建桥将eth1以太网口与所创建的虚拟网口连通，因此升级客户端在完成目标地址的设置后，可将报文发送至主机上对应的虚拟网口。
可选地，为了进一步提高报文的传送效率，主机20还设置为：给需要接收的报文添加记号(mark)标记，以使所述主机20的虚拟网口仅接收存在mark标记的报文。
可在主机20上对从升级客户端30发送过来的大量报文中，给需要接收的报文添加上mark标记，以保证主机20上的虚拟网口只能收到制定有mark标记的报文。使得对流经虚拟网口的报文添加标记，方便后面进行过滤、丢弃和虚拟网口无关的报文，减少了对垃圾报文的接收，大大提高了效率。报文添加mark标记如下所示：
ebtables-t broute-A BROUTING-p IPv4--ip-destination 192.168.1.2-j mark--set-mark 2--mark-target CONTINUE
ebtables-t broute-A BROUTING-p ARP--arp-ip-dst 192.168.1.2-j mark--set-mark 2--mark-target CONTINUE
mark标记报文控制如下所示：
ebtables-A FORWARD-o eth0.2--mark！2-j DROP
虚拟网口eth0.2仅处理mark标记为2的报文。
主机20还设置为：将所述目标地址修改为嵌入式设备40的IP地址，并将所述虚拟网口对应的VLAN标识添加至所述报文；
在主机20的NAT(Network Address Translation，网络地址转换)上将目标地址修改为嵌入式设备40的IP地址，以便嵌入式设备40在接收到报文后，可对报文中携带的目标地址进行校验。主机20在报文中添加虚拟网口的VLAN标识，以便主机20根据VLAN标识将报文转发至交换机10上对应的VLAN。
主机20还设置为：根据所述VLAN标识将所述报文通过交换机10上与所述VLAN标识对应的VLAN，转发至与所述VLAN连接的嵌入式设备40；
由于主机20上所建立的虚拟网口与eth0以太网口连接，而该eth0以太网口又通过网线与交换机10的trunk接口连接，同时在交换机10划分有不同的VLAN，每个VLAN通过网络与待升级的嵌入式设备40连接，主机20上不同虚拟网口的VLAN标识与交换机10上划分不同的VLAN标识匹配。因 此，当报文到达主机20后，主机20可根据虚拟网口的VLAN标识将报文发送至交换机10上与VLAN标识对应的VLAN，再由交换机10通过VLAN将报文发送至与其连接的嵌入式设备40。
嵌入式设备40，设置为：校验所述目标地址正确后反馈消息至升级客户端30，并从升级客户端30下载升级文件进行升级。
嵌入式设备40在接收到报文后，对目标地址进行校验。由于在上述已将目标地址修改为嵌入式设备的IP地址，因此嵌入式设备40可判断目标地址是否与自身的IP地址一致，若一致则验证通过，并反馈消息至升级客户端30，然后下载升级文件进行升级。
可选地，嵌入式设备40还设置为：将携带源IP地址的消息通过与其连接的交换机10对应的VLAN，发送至在与所述VLAN的标识匹配的主机20上对应的虚拟网口；
主机20还设置为：将所述源IP地址修改为虚拟网口的IP地址后转发至升级客户端30；
升级客户端30还设置为：根据所述虚拟网口的IP地址发送携带升级文件版本的升级指令至嵌入式设备40；
嵌入式设备40还设置为：在接收到所述升级指令后，通过升级客户端30的下载服务器下载在所述升级指令中携带的对应版本的升级文件进行升级。
嵌入式设备40可将携带源IP地址的消息发送至与其连接的交换机10上的VLAN，此时，该源IP地址可为嵌入式设备的IP地址。然后可根据交换机10所划分的VLAN与在主机20上创建多个虚拟网口的对应关系，通过交换机10上VLAN的标识将消息发送至主机20上对应的虚拟网口。可在主机20上将消息中的源IP地址修改为虚拟网口的IP地址，然后将消息发送至升级客户端30。升级客户端30在接收到嵌入式设备40反馈的消息后，可根据消息中的虚拟网口的IP地址确定是哪个嵌入式设备40反馈的消息。升级客户端30可根据反馈的消息发送升级指令至对应的嵌入式设备40，该升级指令可包括升级文件版本及名称。嵌入式设备40在接收到升级指令后，可从上 述升级客户端发送过来的报文中提取升级文件的版本号、FTP服务器的用户名及密码等消息，然后，可通过升级客户端30的FTP服务器下载相应版本的升级文件，然后可对下载的升级文件进行校验，若是所需版本的升级文件，则可烧写FLASH进行升级。若目标地址验证不通过，则嵌入式设备40可丢弃该报文。
可选地，在嵌入式设备40完成升级后，嵌入式设备40还设置为：将升级结果返回升级客户端30。
如果升级成功，则嵌入式设备40可回送升级成功的消息至升级客户端30；如果升级失败，则嵌入式设备40可回送升级失败的消息至升级客户端30。升级客户端30在接收到升级结果后，可以是通过对话框的形式显示“升级成功”或者“升级失败”的消息，也可以是通过语音播报的消息进行播报，或者是通过发短信或者邮件通知用户，也可以是通过其他的形式通知用户。从而使得在嵌入式设备40出厂时，可通过本设备批量升级方法由生产线对设备进行批量升级等操作，从而提升工作效率，减低人力成本。或者在嵌入式设备40返修时，可通过本设备批量升级方法由返修中心对设备进行批量升级等操作，从而提升工作效率。
通过本发明实施例，在交换机10上划分不同的VLAN连接嵌入式设备40，在主机20上创建多个虚拟网口及创建桥后，设置不同虚拟网口的不同VLAN标识与交换机10上所划分不同VLAN的标识匹配，并将多个虚拟网口与连接升级客户端30的以太网口加入到桥中，以使交换机10、主机20及嵌入式设备40之间形成连接通路。升级客户端30将携带目标地址的报文发送至主机20上对应的虚拟网口后，主机20将目标地址修改为嵌入式设备40的IP地址，并根据虚拟网口的VLAN标识将报文通过交换机10上与VLAN标识对应的VLAN转发至与该VLAN连接的嵌入式设备40。嵌入式设备40校验目标地址正确后反馈消息至升级客户端30，并从升级客户端30下载升级文件进行升级。实现了通过对主机20划分虚拟网口及对交换机10划分VLAN等操作，使得升级环境一次配置，多次使用，通过NAT映射、VLAN隔离等技术实现对设备的访问。在对嵌入式设备40进行批量升级时无需修改嵌入式设备40的IP地址，减少升级客户端30和嵌入式设备40之间的交互流程， 操作简单明了，提高了对嵌入式设备40批量升级的效率。
