可选地，该适配器用于对该终端设备进行快速充电。
具体地说，在本发明实施例中，当终端设备100与适配器连接时，该第二处理器120可以通过，例如，图2所示的通道1和通道3与适配器通信连接，从而，可以确定该适配器的类型，例如，是否是用于对该终端设备100进行快速充电的适配器。并且，该第二处理器120确定该适配器的类型的方法和过程可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
可选地，该第二处理器还用于在确定该适配器用于对该终端设备进行快速充电之前，禁止该第一处理器与该适配器之间的通信。
具体地说，在本发明实施例中，当该终端设备100通过例如USB接口与外部设备连接时，该第二处理器120可以判定该外部设备的类型，作为该外部设备的类型，可以列举：普通适配器(即，对终端设备100的充电不受第一处理器110的控制)、快速充电器或其他终端设备(例如，计算机设备)。
并且，当第二处理器120判定所连接的外部设备的类型为用于对该终端设备100进行快速充电的适配器时，可以允许第一处理器110与该外部设备进行通信，例如，第一处理器110可以控制图2中所示开关，以使通道2与通道3连通。

具体地说，在本发明实施例中，第二处理器120还可以获取适配器的相 关信息(例如，该适配器的品牌、型号或制造商等)。这里，该适配器的相关信息可以是该适配器发送给第二处理器120的，或者，该适配器的相关信息可以是用户通过终端设备的输入器件等输入至第二处理器120的，本发明并未特别限定。
从而，在第二处理器120还可以将该适配器的相关信息(例如，与上述请求信息承载于同一报文)发送至服务器，从而，服务器可以根据该适配器相关信息，确定能够实现对该适配器的控制的固件。从而，能够进一步提高本发明的实用性和可靠性。
另外，上述在第二处理器120获取固件的过程可以是开机后自动完成，也可以是根据用户输入的指令完成，可以是周期性执行，还可以是由服务器触发完成，本发明并未特别限定。
下面，对该第一处理器110从第二处理器120获取固件的过程进行详细说明。
在本发明实施例中，该第一处理器110中设置有第一通信接口115，该第一通信接口115可以用于该第一处理器110与第二处理器120之间传输固件。并且，例如，在终端设备100刚出厂、固件升级失败或被格式化而还原出厂配置时，第一处理器110中未存储固件。
在本发明实施例中，当第一处理器110中未存储固件时，该第一通信接口115处于开启状态。
从而，第二处理器120可以通过该第一通信接口115，将所获取的固件传输至第二处理器120。
另外，在本发明实施例中，该第一通信接口115除了固件或固件更新文件(随后，对该“固件更新文件”进行详细说明)以外还可以传输其他数据或信息，本发明并未特别限定。
需要说明的是，在本发明实施例中，该第一通信接口115可以为I2C(Inter－Integrated Circuit)接口，I2C为两线式串行总线的接口，用于连接处理器及其外围设备。是微电子通信控制领域广泛采用的一种总线标准。它是同步通信的一种特殊形式，具有接口线少，控制方式简单，器件封装形式小，通信速率较高等优点。
根据本发明实施例的终端设备，在终端的第一处理器设置第一通信接口，并使该第一通信接口在该第一处理器中未存储固件时处于开启状态，从 而，在该第一处理器中未存储固件时，第二处理器能够通过该第一通信接口将从服务器获取的固件传输至该第一处理器，进而，第二处理器能够读取该记录在固件中的控制指令，以控制该适配器对该终端设备进行充电，能够根据所连接的适配器，从服务器获取与该适配器相对应的固件，从而，能够提高基于终端设备的控制的充电方式的实用性和通用性。
需要说明的是，在本发明实施例中，第一处理器110在获取固件后，可以对该固件进行存储，在本发明实施例中，该“存储”是指，第一处理器110可以将该固件存储在内置与该第一处理器110中的存储介质内，或者，第一处理器110也可以将该固件存储在该终端设备100中与该第一处理器110通信连接的存储器中，本发明并未特别限定。
另外，以上列举的第一处理器110获取固件的方法仅为示例性说明，本发明并未限定于此，例如，该固件也可以是在第一处理器110的生成制造过程中，有制造商存储在第一处理器110中。
在该第一处理器中存储有固件时，该第一通信接口处于关闭状态。
具体地说，在本发明实施例中，当第一处理器110中存储有固件时，该第一通信接口115处于关闭状态，从而，能够避免固件的重复传输，节约终端设备的能耗，减少第一处理器110和第二处理器120的负担。
随着硬件产品的更新换代以及技术的发展，可能存在原有固件不能满足用户需求的情况(例如，固件出现漏洞等情况)，因此，需要对固件进行升级。
现有技术中，由于固件是在终端设备的生产制造时存储在处理器中，因此，如果需要对固件进行升级，只能将终端设备返厂维修，严重影响了用户的正常使用，并且提高了产品的成本。
鉴于以上问题，本发明还提供了为第一处理器110中存储的固件进行升级的方法。即：
在本发明实施例中，该第二处理器120可以控制该终端设备(例如，终端设备的收发器等)通过例如无线通信或有线通信等方式服务器获取固件更新文件。
在本发明实施例中，固件更新文件用于对固件进行更新升级，并且，该固件更新文件的生成方法以及对固件更新升级的过程可以与现有技术相似，这里为了避免赘述，省略其详细说明。
作为示例而非限定，该服务器的标识(或者说，能够唯一标识该服务器的信息，例如，该服务器的URL地址或IP地址)可以预先存储在该终端设备100(例如，在该终端设备100中与该第二处理器120相连接的存储器)内，从而，第二处理器120可以根据该服务器的标识，将用于请求服务器下发固件更新文件的请求信息传输至该终端设备100，并且，该请求信息还可以包括该终端设备100的相关信息(例如，终端设备100的手机号码等)，以便于服务器在根据该终端设备100的相关信息对该终端设备100进行鉴权验证，并在通过验证后，将固件更新文件下发至终端设备100。
作为示例而非限定，该请求信息中可以携带该终端设备100的相关信息(例如，该终端设备100的品牌、型号或制造商等)从而，服务器可以根据该终端设备100的相关信息，确定该终端设备100可能连接的适配器所对应的固件更新文件。从而，能够进一步提高本发明的实用性和可靠性。
另外，在本发明实施例中，该固件更新文件可以是第二处理器120根据用户操作而从服务器获取，也可以是第二处理器120周期性向服务器发起请求，并从服务器获取，还可以是服务器主动下发至第二处理器120，例如，服务器可以将固件更新文件连同针对该终端设备100的操作系统的更新文件一同下发至终端设备100。
下面，对该第一处理器110从第二处理器120获取固件更新文件的过程进行详细说明。
在本发明实施例中，该第一处理器110中设置有第一通信接口115，该第一通信接口115可以用于该第一处理器110与第二处理器120之间传输固件或固件更新文件。并且，当第一处理器110中存储有固件时，该第一通信接口115处于关闭状态。
在本发明实施例中，第一处理器110中还设置有保持开启状态的第二通信接口117，该第二通信接口117用于传输用于触发第一通信接口115开启的触发信息。
在本发明实施例中，该触发信息可以是具有规定模式的电平信号，例如，一个或多个低电平信号、一个或多个高电平信，或者高低电平信号的组合。或者，该触发信息也可以是数字信号或模拟信号，本发明并未特别限定。
作为示例而非限定，在本发明实施例中，该第二通信接口117可以为通用输入/输出(General Purpose Input Output，GPIO)接口。
在本发明实施例中，该触发信息可以是第二处理器120发送的(即，情况1)，也可以是适配器发送的(即，情况2)，下面，分别对以上两种情况下的处理过程进行详细说明。
情况1
可选地，该第一触发信息具体是该第二处理器发送的。
具体地说，如图2所示，在本发明实施例中，第二处理器120可以通过该第二通信接口117与该第一处理器110连接，从而，第二处理器120可以通过第二通信接口117向第一处理器110发送上述触发信息。
可选地，该第一触发信息具体是该第二处理器在获取固件更新文件后发送的。
具体地说，在本发明实施例中，第二处理器120可以在如上所述获取固件更新文件之后，向第一处理器110发送上述触发信息，从而能够及时对存储在第一处理器110中的固件的更新。
应理解，以上列举的第二处理器120向第一处理器110发送上述触发信息的时机仅为示例性说明，本发明并未限定于此，例如，第二处理器120也可以周期性或在终端设备100重启动后向第一处理器110发送上述触发信息。
情况2
可选地，该第一触发信息具体是该适配器发送的。
具体地说，如图3所示，在本发明实施例中，在终端设备100与用于快速充电的适配器连接后，在本发明实施例中，适配器可以通过该第二通信接口117与该第一处理器110连接，从而，适配器可以向该处理器110向第一处理器110发送上述触发信息。
可选地，该第一处理器还用于通过该第一通信接口，向该第二处理器发送版本指示信息，该版本指示信息用于指示该第一处理器所存储的固件的版本；
该第二处理器还用于根据该版本指示信息，确定向该第一处理器传输固件更新文件。
具体地说，在本发明实施例中，第一处理器110在接收到触发信息之后，开启上述第一通信接口115，并且，可以通过该第一通信接口115向第二处理器120发送存储在第一处理器110(或者说，存储在与该第一处理器110 相连接的存储器)中的固件的版本信息。
第二处理器120在接收到该版本信息后，可以确定所获取的固件更新文件是否能够用于对存储在第一处理器110中的固件进行更新，例如，如果通过固件更新文件更新后的固件是存储在第一处理器110中的固件的升级版本(例如，通过固件更新文件更新后的固件的版本号大于存储在第一处理器110中的固件的版本号)，则第二处理器120可以判定所获取的固件更新文件能够用于针对存储在第一处理器110中的固件的更新升级，从而，可以通过第一通信接口115向第一处理器110发送固件更新文件。
可选地，该第一处理器具体用于在确定该终端设备在最近一次重新启动后，首次与该适配器连接之后，通过该第一通信接口，向该第二处理器发送该版本指示信息。
具体地说，通常情况下，在终端设备100进行操作系统升级后会重新启动，并且，第一处理器110所使用的固件通常会随操作系统同时升级，因此，在终端设备100重新启动后，该固件需要升级的可能性较高，并且，该第一处理器110用于控制所连接的适配器，因此，在本发明实施例中，第一处理器110可以根据终端设备100的重新启动情况和适配器的连接情况，判定是否需要向第二处理器120发送当前存储的固件的固件版本信息。
例如，如果终端设备100当前的状态为：终端设备100在最近一次重新启动后，首次与用于快速充电的适配器连接，则向第二处理器120发送当前存储的固件的固件版本信息。
或者，如果终端设备100当前的状态为：终端设备100在最近一次重新启动后，非首次与用于快速充电的适配器连接，则禁止向第二处理器120发送当前存储的固件的固件版本信息。
从而，能够减少第二处理器120和第一处理器110之间的无谓交互，减少能耗和处理负担。
并且，作为判定该终端设备100是否是在最近一次重新启动后首次与该适配器连接的的方法，可以设置计数器，每次与适配器连接后，该计数器增加，并且，当终端设备100重启后，该计数器置零，并重新计数。
在本发明实施例中，该计数器的功能可以集成在第二处理器120或第一处理器110中，本发明并未特别限定。
第一处理器110在从第二处理器120获得固件更新文件后，可以对所存 储的固件进行更新，并且，该更新的过程可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
图4示出了本发明实施例的终端设备100获取固件以及对该固件进行更新的具体流程，如图4所示：
在S210，第二处理器120可以从服务器获取固件和/或固件更新文件；
在S220，第二处理器120可以确定第一处理器110中的第一通信接口115是否开启，例如，第二处理器120可以通过第一通信接口115向第一处理器110发送检测信号，
在S220，如果第二处理器120能够获得第一处理器110的响应，则可以判定第一通信接口115处于开启状态，即，第一处理器110中未存储固件，从而，在S230，第二处理器120可以通过该第一通信接口115向第一处理器110传输固件。并且，在固件传输完成后，第一处理器110可以向第二处理器120发送校验信息，以指示所传输的固件是否能够正常使用，从而，在S235，第二处理器120检测该校验信息，如果判定固件能够正常使用，则转至S240，如果判定固件不能够正常使用(例如，传输失败)，则重新传输固件。
在S220，如果第二处理器120不能够获得第一处理器110的响应，则可以判定第一通信接口115处于关闭状态，即，第一处理器110中存储有固件，从而在S240，第二处理器120判定是否有用于快速充电的适配器插入。
在S240，如果第二处理器120判定为有适配器插入，则在S250，第二处理器120进行控制，以使第一处理器110与适配器通信连接，并且，第二处理器120或适配器可以向第一处理器110发送触发信息，以使第一通信接口115开启。
在S240，如果第二处理器120判定为没有适配器插入，则继续等待。
在S260，第一处理器110可以判定为终端设备100的状态是否为最近一次重新启动后首次与适配器连接。
在S260，如果判定为是，则在S270，第一处理器110可以向第二处理器120上报所存储的固件的固件版本信息。
在S260，如果判定为否，则在S275，进行快速充电。
在S280，第二处理器120根据第一处理器110上报的固件版本信息，判定是否需要对第一处理器110所存储的固件的固件进行更新。
在S280，如果判定为否，则在S275，进行快速充电。
在S280，如果判定为是，则，在S290，第二处理器120通过该第一通信接口115向第一处理器110传输固件更新文件。并且，在固件更新文件传输完成后，第一处理器110可以向第二处理器120发送校验信息，以指示所传输的固件是否能够正常使用，在S295，第二处理器120检测该校验信息，如果判定固件能够正常使用，则转至S240，如果判定固件不能够正常使用(例如，传输失败)，则重新传输固件。
根据本发明实施例的终端设备，在终端的第一处理器设置第一通信接口，并使该第一通信接口在该第一处理器中存储有固件时处于关闭状态，从而，在该第一处理器中存储有固件时，第二处理器或适配器，能够向该第一处理器发送触发信息，以使该第一通信接口开启，第二处理器能够通过该第一通信接口将从服务器获取的固件更新文件传输至该第一处理器，从而能够完成固件升级，能够提高基于终端设备的控制的充电方式的实用性和通用性。
