首先介绍，如何在终端设备内部选择一个或多个温度传感器；
在本申请的一示例中，可仅在终端设备的冷区域选择一个或多个第一温度传感器。然后仅基于所述第一温度传器所采集的温度信息，确定所述终端设备的外部环境温度。

在本申请实施例中，关于如何根据第一温度传感器与热源的位置关系，确定第二温度传感器，可采用以下方式：
由于终端设备内的热源一般会有三个及以上，比如，系统级芯片(System on Chip，SOC)、功率放大器(power amplifier，PA)以及照相机(camera)等。所述热源在终端设备内可 集中分布，也可分散分布。
因此，在本申请实施例中，当终端设备内的热源集中分布时，所述第二温度传感器的数量可为1个。所述第二温度传感器位于所述热源的中心与所述第一温度传感器的连线上，也可称为热源在第一温度传感器与第二温度传感器的连线上均匀分布。在本申请实施例中，以终端设备的热源为两个，分别为第一热源和第二热源，且第一热源和第二热源集中分布为例，详细说明如何选择第二温度传感器。可首先确定第一热源与第二热源的中心，然后连接第一温度传感器与第一热源和第二热源的中心，最后，在所述第一温度传感器与第一热源和第二热源中心的连接线上，选择第二温度传感器。比如，如图1所示，当第一热源与第二热源上下分布时，所述第二温度传感器可位于第一温度传感器与热源之间(比如，图1中的方式a)，所述第二温度传感器也可位于第一温度传感器和热源的左侧(比如，图1中的方式b)，所述第二温度传感器也可位于热源和第一温度传感器的右侧(比如，图1中的方式c)。所述第二温度传感器也可与第一热源和第二热源的中心重叠(比如，图1中的方式d)。再比如，如图2所示，当第一热源与第二热源左右分布时，所述第二温度传感器可位于第一温度传感器与第一热源和第二热源之间(比如，图2中的方式a)，所述第二温度传感器也可位于第一温度传感器与第一热源和第二热源的左侧(比如，图2中的方式b)，所述第二温度传感器也可位于第一温度传感器与第一热源和第二热源的右侧(比如，图2中的方式c)，所述第二温度传感器也可与第一热源和第二热源的中心重叠(比如，图2中的方式d)，所述第二温度传感器也可与第一热源重叠(比如，图2中的方式e)，所述第二温度传感器也可与第二热源重叠(比如，图2中的方式f)。
需要说明的是，在本申请实施例中，并不限定第一温度传感器与第一热源和第二热源的位置关系，在图1和图2的示例中，仅是以第一温度传感器位于第一热源和第二热源的左侧为例进行举例说明，在本申请的实施例中，第一温度传感器可位于第一热源和第二热源的左侧，所述第一温度传感器也可位于第一热源和第二热源的右侧，甚至所述第一温度传感器也可与第一热源和第二热源的中心重叠，在此不再限定。
在本申请实施例中，当终端设备的热源分散时，可按热源的集中程度，将分散的热源划分为多个集中热源，然后在每个集中热源的中心与第一温度传感器的连线上选择一个第二温度传感器，所述第二温度传感器位于第一温度传感器与集中热源中心的连线上，也可称为分散热源中的每个集中热源在第一温度传感器与第二温度传感器的连线上均匀分布。比如，当所述终端设备的热源分散分布时，所述分散分布的热源可包括N个集中热源，所述第二温度传感器的数量为N个，N个第二温度传感器中的第i个第二温度传感器，位于第i个集中热源与所述第一温度传感器的连线上，所述N为大于或者等于2的整数，所述i为大于或者等于1，小于或者等于N的整数。
比如，如图3所示，终端设备内包括9个热源，且9个热源在终端设备内分散，那么可按照热源的集中程度，将9个分散热源，划分为3个集中热源，分别为集中热源1、集中热源2以及集中热源3。其中，集中热源1内包括3个热源，分别为热源1、热源2以及热源3。集中热源2内包括3个热源，分别为热源4、热源5以及热源6。集中热源3内包括3个热源，分别为热源7、热源8以及热源9，那么可在集中热源1的中心与主传感器的连线上设置一第二温度传感器，所述第二温度传感器可位于集中热源1与第一温度传感器之间，也可位于集中热源1与第一温度传感器的外侧，在此不再赘述。在图3中，是以第二温度传感器位于集中热源1与第一温度传感器的外侧为例，进行说明的。同理，可 在集中热源2的中心与第一温度传感器的连接上设置一个第二温度传感器，在集中热源3的中心与第一温度传感器的连线上设置一个第二温度传感器。
然后介绍，基于所选择的温度传感器，建立热阻网络模型。
在本申请实施例中，设定在终端设备内选定n个温度传感器，分别为温度传感器1、温度传感器2、温度传感器3，依次类推，直至温度传感器n，所述n为大于等于1的整数。终端设备内包括i个热源，分别为热源1、热源2，依次类推，直至热源i，所述i为大于等于1的整数，所建立的热阻网络模型，可如图4所示。需要说明的是，图4所示的n个温度传感器，可均位于终端设备的冷区域，即所述n个温度传感器均为上述所述第一温度传感器，或n个温度传感器均为上述所述主温度传感器。或者，图4所示的n个温度传感器中，一个温度传感器位于终端设备的冷区域，其余n-1个温度传感器位于所述热源中心与上述冷区域温度传感器的连线上。也就是说，图4所示的n个温度传感器中，一个温度传感器为上述第一温度传感器，或称n个温度传感器中，一个温度传感器为上述主温度传感器。其余n-1个温度传感器为上述第二温度传感器，或者称其余n-1个温度传感器为辅温度传感器。
通过图4可以看出，每个温度传感器的温度，受i个热源的叠加影响，且每个温度传感器的温度与终端设备的外部环境温度的差值，可通过热阻R体现。所述R＝(T1-T2)/(P1+P2...+Pi，所述T1代表温度传感器的温度，所述T2代表终端设备外部环境的温度，所述Pi代表第i个热源传递到该温度传感器的功率。
最后介绍，基于如图4所示的热阻网络模型，建立训练算法。
在本申请实施例中，所述训练算法，可基于所选定温度传感器的温度信息，以及终端设备内的系统参数，来确定终端设备的外部环境温度，所述系统参数包括不限于终端设备的电池输出电流、屏幕亮度和器件工作状态。其中，所述器件工作状态包括SOC频点、PA发射功率、WIFI强度以及声音输出(speaker)模块功耗等。

基于以上思路，本申请提供一种确定外部环境温度的方法，如图5所示，所述方法包括：
步骤S51：终端设备通过第一温度传感器采集温度信息。
其中，所述第一温度传感器位于所述终端设备的冷区域，关于终端设备的冷区域，以及第一温度传感器的说明，可参见上述记载，在此不再赘述。

在本申请的另一示例中，温度传感器可每间隔n时长，采集一次温度信息。比如，温度传感器1可在时刻A采集一次温度信息，然后采用上述记载的方法，获得在时刻A传感器1所对应的外部环境温度。同理，也可获得在时刻A传感器2所对应的外部环境温度，在时刻A传感器3所对应的外部环境温度。最后，可将可将3个温度传感器在时刻A所对应的外部环境温度求均值，作为时刻A所对应的外部环境温度。同理，也可获得时刻B所对应的外部环境温度，时刻C所对应的外部环境温度等。最后，再将多个时刻所对应的外部环境温度，求均值，作为当前时刻终端设备的外部环境温度。
