Description

一种控制终端的方法及装置 技术领域
本发明实施例涉及但不限于数据通信，尤指一种控制终端的方法及终端。
背景技术
目前，终端配备的电池包括镍镉电池、镍氢电池和锂离子电池等。其中，电池的工作温度为0～40℃。在环境温度较低时，电池的活性会下降以导致电池的电量消耗非常快，不能满足终端的正常工作需求。并且，终端通常会设置温度阈值，在自身的电池温度低于该温度阈值时自动关机。
现有技术中，为了避免终端在环境温度较低时电池的电量消耗过快或者出现自动关机的情况，终端通过检测自身电池的温度，并根据检测的温度来判断是否对终端电池进行加热，从而保证终端在低温时能够实现自身电池温度的提高。

本发明的较佳实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
实施例一
图1为本发明实施例提供的一种控制终端的方法的流程示意图一，包括：
步骤101：当加热功能触发后的预设时间段到达时，检测终端的当前电池温度；
其中，预设时间段为预设的在终端的加热功能触发后检测终端当前电池温度的时间间隔，用于在终端的加热功能触发后定时检测终端的当前电池温度。
在实际应用中，终端检测当前电池温度包括多种方式，例如，利用终端内部设置的温度感应器来检测当前电池温度，本发明实施例对此不做具体限制。
需要说明的是，终端包括智能手机、平板电脑、无线保真(WIFI，WIreless-Fidelity)热点等内置电池的终端，本发明实施例对终端的种类不做具体限制。
另外，终端的电池包括但不限于锂电池、锂聚合物电池以及其他智能终端使用的电池。本发明实施例对终端的电池种类不做具体限制。
可选地，参见图2所示，在步骤101之前，还包括步骤100：当加热功能触发时，根据预设功率控制参数对终端的电池进行加热。
其中，预设功率控制参数为终端在加热功能触发时(第一次进行加热时)，默认的对终端的电池进行加热的功率控制参数。
其中，功率控制参数为控制加热终端电池时的加热功率的参数，包括加热电压或加热电流。
需要说明的是，终端可以通过多种方式触发加热功能，例如，终端可以定时触发加热功能，终端也可以根据用户的需求触发加热功能。本发明实施例对终端触发加热功能的方式不做具体限制。
步骤102：当当前电池温度小于预设温度阈值时，根据预设的策略确定功率控制参数；
其中，预设温度阈值为预先设置的判断是否对终端电池进行加热的温度阈值。预设温度阈值可以根据实际情况进行设置。一般情况下，在电池温度为-10℃时，由于电池温度过低会出现终端自动关机的现象。那么，为了避免出现终端自动关机的现象，预设温度阈值需要设置在-10℃以上，例如，预设温度阈值设置为-5℃。
其中，预设的策略用于确定阶梯性的功率控制参数。例如，预设的策略可以包括，根据当前电池温度与预设温度阈值的温度差值，以及温度差值与功率控制参数的映射关系，确定对应的功率控制参数。其中，温度差值与功率控制参数的映射关系，可以设置为随着温度差值的增大，增加功率控制参数的值以便增加根据功率控制参数计算得到的加热功率。这样一来，实现了动态的阶梯性的调整加热功率，从而实现了快速对终端的电池进行加热。当然，预设的策略还可以包括其他方式，本发明实施例对此不做具体限制。
其中，功率控制参数为控制加热终端电池时的加热功率的参数，包括加热电压或加热电流。由功率计算公式可知，在电阻阻值一定的情况下，通过提高加热电压或者提高加热电流，便可以提高加热功率，可以看出，加热电压或加热电流为控制加热功率的功率控制参数。
具体地，根据预设的策略确定功率控制参数包括：判断预设时间段为加热功能触发后的第i次预设时间段，i大于或等于1；根据第i次预设时间段和预设的预设时间段的顺序与功率控制参数之间的对应关系，确定功率控制参数；
举例来说，若预设时间段为10分钟，那么当终端的加热功能触发后的10分钟到达时，检测终端的当前电池温度T1；当T1小于预设温度阈值时，判断预设时间段为加热功能触发后的第1次预设时间段；根据第1次预设时间段和预设的预设时间段的顺序与功率控制参数之间的对应关系，确定功率控制参数X1；根据X1对终端的电池进行加热。进一步地，当终端的加热功能触发后的20分钟到达时，检测终端的当前电池温度T2；当T2仍然小于预设温度阈值时，判断预设时间段为加热功能触发后的第2次预设时间段；根据第2次预设时间段和预设的预设时间段的顺序与功率控制参数之间的对应关系，确定功率控制参数X2；根据X2对终端的电池继续进行加热，这样重复执行直到终端的当前电池温度大于或等于预设温度阈值，则停止加热终端的电池。可以看出，根据第i次预设时间段和预设的对应关系确定功率控制参数，说明功率控制参数是动态可调的。
实际应用中，若当终端的加热功能触发后(第一次加热后)的第i次预设时间段到达时，终端的当前电池温度仍然小于预设温度阈值，则可以通过功率控制参数来增加加热功率。表1示出了预设的预设时间段的顺序与功率控制参数的顺序之间的对应关系。
顺序序号i 第i次预设时间段 第i个功率控制参数 第i个加热功率
1 第1次预设时间段 X1 P1
2 第2次预设时间段 X2 P2
3 第3次预设时间段 X3 P3
表1
需要说明的是，第i个加热功率为根据第i个功率控制参数确定的加热功率，且P1<P2<P3。
通过表1，可以看出，当终端的加热功能触发后的第i次预设时间段到达时，终端的当前电池温度仍然小于预设温度阈值，可以通过对应的功率控制参数即X1、X2、X3将加热功率进行动态提高，从而避免了环境温度极低时终端电池温度的持续降低。
优选地，预设时间段的顺序与功率控制参数之间的对应关系的设置方法 包括：根据预设的预设时间段的顺序，将预设功率控制参数按照预设规则迭代，并得到对应的功率控制参数。
可理解地，随着预设时间段的顺序的增加，由对应的功率控制参数控制得到的加热功率是阶梯性递增的，从而有效提高了加热速度。
需要说明的是，预设规则可以包括多种迭代算法，例如，线性规划、非线性规划、最小二乘法等，本发明实施例对此不做具体限制。
举例来说，表2示出了预设时间段的顺序与功率控制参数的顺序之间的对应关系，并以功率控制参数为加热电压，预设功率控制参数为1.4V，迭代参数为0.2V为例进行说明。
顺序序号i 第i次预设时间段 第i个加热电压
1 第1次预设时间段 1.6V
2 第2次预设时间段 1.8V
3 第3次预设时间段 2.0V
表2
由表2可以看出，将预设功率控制参数1.4V作为迭代的初始值按照预设规则迭代，即随着预设时间段的顺序序号的增加，对应的加热电压按照迭代参数0.2V依次递增。具体为：
与第1次预设时间段对应的第1个加热电压为，1.4V与迭代参数0.2V的和，即1.6V，并将第1个加热电压作为下一次迭代的初始值；
与第2次预设时间段对应的第2个加热电压为，上一次迭代的结果即第1个加热电压1.6V与迭代参数0.2V的和，即1.8V；
与第3次预设时间段对应的第3个加热电压为，上一次迭代的结果即第2个加热电压1.8V与迭代参数0.2V的和，即2.0V。
需要说明的是，还可以通过另一种方式来实现上述迭代方法，包括：将预设功率控制参数1.4V作为迭代的初始值，随着预设时间段的顺序序号的增加，对应的加热电压为预设功率控制参数1.4V，与迭代参数0.2V的对应倍数的和。具体为：
与第1次预设时间段对应的第1个加热电压为，预设功率控制参数1.4V，与迭代参数0.2V的一倍即0.2V的和，1.6V；
与第2次预设时间段对应的第2个加热电压为，预设功率控制参数1.4V，与迭代参数0.2V的两倍即0.4V的和，1.8V；
与第3次预设时间段对应的第3个加热电压为，预设功率控制参数1.4V，与迭代参数0.2V的三倍即0.6V的和，2.0V。
可选地，在步骤101之后，且在判断预设时间段为加热功能触发后的第i次预设时间段之前，方法还包括：当当前电池温度小于预设温度阈值时，产生用于开启终端的电池加热的第一中断信号；根据第一中断信号触发第一控制信号；相应地，根据第i次预设时间段和预设的预设时间段的顺序与功率控制参数之间的对应关系，确定功率控制参数，具体包括：根据第一控制信号、第i次预设时间段，和预设的预设时间段的顺序与功率控制参数之间的对应关系，确定功率控制参数。
需要说明的是，第一中断信号用于开启终端的电池加热。第一控制信号，用于触发功率控制参数的确定。可以看出，终端根据第一中断信号确定开启在当前预设时间段内的终端的电池加热，而根据功率控制参数确定对终端的电池进行加热的加热功率。
步骤103：根据功率控制参数对终端的电池进行加热。
可理解地，对终端的电池进行加热的功率控制参数是根据预设策略动态可调的，如此避免了通过单一的功率控制参数加热终端的电池，提高了加热终端电池的加热速度。
实际应用中，对终端的电池进行加热时，可以利用恒定阻值的电热丝、PTC加热片、加热膜、电热片、电热器、动力电池加热膜、电热板等加热元件进行加热，本发明实施例对此不做具体限制。
另外，加热元件可以设置在紧贴电池的位置，以便更好的对电池进行加热，提高加热效率。
需要说明的是，在对终端的电池进行加热后，终端的当前电池温度会改变，且当加热功能触发后的下一次预设时间段到达时，重复执行步骤101， 直到终端的当前电池温度大于或等于预设温度阈值。
可选地，参见图3所示，在步骤101之后，方法还包括步骤104：
当当前电池温度大于或等于预设温度阈值时，停止对终端电池的加热。
可理解地，在终端的当前电池温度大于或等于预设温度阈值时，说明终端当前电池温度可以满足终端的正常工作，因此，无需对终端电池进行加热，因而停止加热终端电池。
可选地，步骤104具体包括：当当前电池温度大于或等于预设温度阈值时，产生用于停止终端的电池加热的第二中断信号；根据第二中断信号停止对终端电池的加热。
在实际应用中，终端在产生用于停止终端的电池加热的第二中断信号之后，还包括：根据第二中断信号触发第二控制信号，其中，第二控制信号用于关闭对第i个功率控制参数的确定。由于终端根据第二中断信号停止对终端电池的加热，因此，终端不需要确定对终端的电池进行加热的加热功率，因而，利用第二控制信号来关闭对第i个功率控制参数的确定。
本发明实施例提供的一种控制终端的方法，当加热功能触发后的预设时间段到达时，检测终端的当前电池温度；当当前电池温度小于预设温度阈值时，根据预设的策略确定功率控制参数；根据功率控制参数对终端的电池进行加热。采用上述技术实现方案，根据预设的策略来动态调整功率控制参数，有效地阻止了终端电池电量消耗过快，快速高效地提高了终端电池温度，快速解决了终端因电池温度过低而自动关机的问题，有效避免了单一功率加热时由于散热大于加热而出现的无法迅速提升终端电池温度的情况。
实施例二
图4为本发明实施例提供的一种控制终端的方法的流程示意图四，该方法包括：
步骤401：获取预设功率控制参数、预设温度阈值以及预设时间段；
其中，功率控制参数为控制加热终端电池时的加热功率的参数。具体地，功率控制参数是动态可调的，例如表1中的X1、X2、X3。
预设时间段为预设的在终端的加热功能触发后检测终端当前电池温度的 时间间隔，用于在终端的加热功能触发后定时检测终端的当前电池温度。
预设温度阈值为预先设置的判断是否对终端电池进行加热的温度阈值。需要说明的是，预设温度阈值根据实际情况进行设置。一般情况下，在电池温度为-10℃时，由于电池温度过低会出现终端自动关机的现象。那么，为了避免出现终端自动关机的现象，预设温度阈值需要设置在-10℃以上，例如，预设温度阈值设置为-5℃。
步骤402：当加热功能触发时，根据预设功率控制参数对终端的电池进行加热；
其中，预设功率控制参数为终端在加热功能触发时，默认的对终端的电池进行加热的功率控制参数。
可理解地，终端可以通过多种方式触发加热功能，例如，终端可以定时触发加热功能，终端也可以根据用户的需求触发加热功能。
步骤403：当加热功能触发后的第i次预设时间段到达时，检测终端的当前电池温度，i大于或等于1；
步骤404：判断出当前电池温度是否小于预设温度阈值，若是，则执行步骤405-步骤408；若否，则执行步骤409-步骤410；
步骤405：产生用于开启终端的电池加热的第一中断信号；
步骤406：根据第一中断信号触发第一控制信号；
步骤407：根据第一控制信号，和第i次预设时间段和预设的预设时间段的顺序与功率控制参数之间的对应关系，确定功率控制参数；
其中，功率控制参数包括加热电压和加热电流。在电阻阻值一定的情况下，通过提高加热电压或者提高加热电流，便可以提高加热功率。
实际应用中，预设时间段的顺序与功率控制参数的顺序之间的对应关系的设置方法，包括：根据预设的预设时间段的顺序，将预设功率控制参数按照预设规则迭代，并得到对应的功率控制参数的顺序。
步骤408：根据功率控制参数对终端的电池进行加热；
其中，第一中断信号用于开启终端的电池加热；第一控制信号，用于触 发第i个功率控制参数的确定。可以看出，终端根据第一中断信号确定开启终端的电池加热，而根据第i个功率控制参数确定对终端的电池进行加热的加热功率。
需要说明的是，在对终端的电池进行加热后，终端的当前电池温度会改变，且当下一次预设时间段到达时，重复执行步骤403，直到终端的当前电池温度大于或等于预设温度阈值。
步骤409：产生用于停止终端的电池加热的第二中断信号；
步骤410：根据第二中断信号停止对终端电池的加热。
综上所述，当加热功能触发后的第i次预设时间段到达时，检测终端的当前电池温度，i大于或等于1；当当前电池温度小于预设温度阈值时，根据第i次预设时间段和预设的预设时间段的顺序与功率控制参数的顺序之间的对应关系，确定第i个功率控制参数；根据第i个功率控制参数对终端的电池进行加热。采用上述技术实现方案，动态调整功率控制参数，有效阻止了终端的电池电量下降过快，快速高效的提高了终端电池温度，进而快速解决了终端因电池温度过低而自动关机的问题，有效避免了单一功率加热时由于散热大于加热而出现的无法迅速提升终端电池温度的情况。
