下面将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特征可以相互任意组合。
图1为本发明实施例提供的控制移动终端中CPU的热插拔操作的方法的流程图。图1所示方法包括：
步骤101、当检测到CPU在预设时间内执行热插拔操作的次数超过预先设置的阈值时，对所述CPU的温度阈值进行调整，其中所述温度阈值用于控制所述CPU执行热插拔操作；

其中，所述对所述CPU的温度阈值进行调整，包括：
所述CPU的温度阈值T1和T2中的至少一个进行调整，其中所述T1和T2均大于0，且T1小于T2。
CPU温度有两个温度阈值，(T1,T2)，到达T2时关CPU，到达T1时，开CPU，因此，在实际应用中，可以通过调整T1的数值大小来控制CPU开启的触发条件，也可以通过调整T2的数值大小来控制CPU关闭的触发条件，当然，也可以对T1和T2均进行调整，来控制CPU开启和关闭的触发条件。
其中，所述对所述CPU的温度阈值进行调整，包括：
减少所述CPU的温度阈值T1的大小，和/或，增大所述CPU的温度阈值T2的大小，其中所述T1和T2均大于0，且T1小于T2。

其中，对所述CPU的温度阈值进行调整，包括：
根据本地预先设置的数值调整策略，对所述CPU的温度阈值进行调整；或者，
输出对所述CPU的温度阈值进行调整的操作信息，并接收对操作信息反馈的操作结果，得到调整后的温度阈值。
在实际应用中，可以通过移动终端自行进行调整，也可以由外部进行调整，通过上述方式，可以实现对温度阈值的管理。
另外，在输出对所述CPU的温度阈值进行调整的操作信息时，输出对数据调整的提示信息，其中所述提示信息包括数值调整的方向和/或数值调整的幅度。
其中，数据调整的方向为增加或减小。
通过输出提示信息，可以外部准确地修改温度阈值，为后续管理提供了准确的依据。
下面以实施例对上述方法作进一步说明：
实施例1(自动调整)
图2为本发明实施例1提供的的控制移动终端中CPU的热插拔操作的方法的流程图。图2所示方法包括：
步骤201：监控CPU前一时间段内开关状态的变化；
步骤202：如果开关状态的变化在一定时间内大于一阈值到步聚203；
在该步骤中，其中时间段或hotplug(热插拔)开关的次数可人为调整或选择。比如场景1：时间段为5分钟，hotplug开关的次数大于了50次；场景2:时间段为1分钟，hotplug开关的次数大于了7次；其中采样频率为1S钟或按人为设定采样一次。
该步骤可以包括：开始采样，据配置的采样频率，采集每个CPU的hotplug状态；采集每个CPU对应的温控的温度计的温度值；如果采样时间到，结束本次采样，并进行计算。以配置的场景2为例，采集1分钟。如果一个CPU的hotplug的次数大于了7次，则需要按一定步长调整该CPU的温度范围值(T1,T2)。一般来说为了控制手机的温度，一般调整T1的值，如果hotplug比较频繁，则调整的幅度大一些。如T1_new＝T1–2度。
多个CPU间的温度范围的调整策略。如果步长小一些，可仅调整hotplug最频繁的CPU的温度范围值，据采样周期，逐步使得每个CPU的 hotplug不频繁。
步骤203：以指定步长，增大相应的温度的范围。清空监控数据，并到S101.
实施例2(手动调整，或据推荐值选择)
图3为本发明实施例2提供的的控制移动终端中CPU的热插拔操作的方法的流程图。图3所示方法包括：
步骤301：查看监控CPU前一时间段内开关状态的变化；并读取相应的温度值.
步骤302：如果开关状态的变化在一定时间内大于一阈值，给出报警，到步聚303；
此处因是手动调整，如果用户看到了hotplug的频繁状态，可以选择由系统推荐的几个配值项。如选择1:把hotplug最频繁的CPU的下限的温度范围调低2度；选择2：把hotplug比较频繁的前2个CPU的温度范围都调低2度；或者用户可手动选择一个或多个CPU对应的温度计的范围(T1,T2)。一般来说T2往上调大于系统默认值，要给用户特别说明，可能设备的温度在使用过程中会比之前要增加。
步骤303：手动调整温度的范围。清空监控数据，并到步骤301。
由上可以看出，通过获取CPU的运行状态，在发现设备CPU频繁开关时，可以选择让设备报警，或自动调节温度范围值，或手机调节，或选择相应的推荐值。
