图; 图。 具体实施方式
在现有技术中, 由于在待机过程中需要定时唤醒移动终端来完成与基 站的交互和对手机状态的检测, 然而, 由于交互和检测的过程电流会比待 机时增大很多, 因此会极大的影响整机的待机性能。
但是, 目前一般手机由于其内在特性, 在手机待机过程中会定时的退 出待机模式以完成射频和基站的交互通讯, 并在这个时间间隙来完成电池 电量、 温度等任务的检测, 在这种情况下, 由于是在固有的唤醒状态下进 行基站交互和状态检测, 符合一般移动终端的要求, 对待机电流没有任何 影响。 但目前智能手机大多采用应用处理器( Application Processor, AP ) + 无线模块 ( Modem ) 的系统架构, 存在不同的工作模式, 比如 AP 工作、 AP和无线模块同时工作等情况, 不同的工作模式下存在不同的交互和检测 需求, 如果都采用上面描述的一般移动终端 Modem工作时, 定时退出进行 交互的唤醒方案, 则当只有 AP工作时, 射频和基站不需要交互, 电池温度 的监测方案也可以优化, 如果还采用与一般移动终端一致的频繁的唤醒机 制, 会加大待机电流, 从而减小待机时间。
有鉴于此, 针对智能手机的这种特点, 本发明实施例中提出了一种智 能手机在不同工作模式下采用不同唤醒机制的方案, 来完成手机与基站的 交互和手机状态 (例如电池电量, 温度) 的检测, 从而达到减小智能手机 的待机电流的目的, 实现在不改变电池容量的前提下有效改善待机时间, 增强电池的续航能力。
具体的, 本发明实施例中提出智能手机在不同的工作模式下采取不同 的唤醒机制的方案, 来完成手机与基站交换和手机状态 (例如电池电量, 温度)检测, 从而实现减小待机电流, 增强待机时间。 由于一般智能手机 目前有两种工作模式: AP工作和 AP+Modem同时工作。 在这两种不同的 情况下, 根据不同工作模式特点, 实施中便可以对手机采取不同的唤醒机 制, 同时, 对手机与基站交互和状态检测采取不同的方法, 从而达到改善 待机电流的目的。 下面对手机架构模式及相应的实施思路进行说明。
目前智能手机架构 艮多采用 AP+Modem 的方案, 存在 AP 工作和 AP+Modem同时工作等多种不同的工作模式。
当只有 AP工作时, 智能手机功能有如个人数字助理( Personal Digital Assistant, PDA ), 不存在射频与基站之间的脉冲 (Burst ) 唤醒, 不需要与 基站进行交互, 因此只需要定时对电池电量及温度等手机状态进行检测即 可。 针对这种情况, 实施中可以通过拉长唤醒时间来避免由于频繁的退出 待机模式而引起的电流, 从而达到减小待机电流的目的。 另一方面, 由于 对手机状态 (例如电池电量, 温度等) 的检测不需要实时进行, 因此实施 中完全可以将这个检测时间拉到足够长(10分钟)后才检测, 甚至可以不 检测, 从而达到尽量少的做手机的唤醒操作的目的, 使的待机过程中退出 待机模式的时间减少, 实现待机电流的减少, 增加待机时间,
当 AP+Modem—起工作时, 由于在 Modem工作时, 本身存在射频与 基站之间的通讯, 需要与基站进行交互, 同时也需要对手机状态 (例如电 池电量, 温度等)进行检测。 针对这种情况, 实施中可以采用与一般移动 终端一样的唤醒机制, 按照协议要求定时唤醒来完成射频与基站之间的交 互, 同时对手机状态 (例如电池电量, 温度等) 的检测放在射频与基站交 互的时间间隙进行, 不会增加唤醒次数, 保证在这种情况下不增加待机电 流。
本发明实施中, 还进一步的提出了将手机电量的高低作为处理的依据 之一, 下面进行说明。
当电池电量比较低的时候, 由于手机很容易进入关机状态, 为避免用 户使用过程中出现突然掉点关机的情况, 需要对手机状态(例如电池电量, 温度等) 的检测变成实时采集的方案, 以便及时提示用户电量低, 关机等 信息。 具体的, 本发明实施例中也提供了相应的技术方案, 即采用硬件比 较器来检测电池电量, 发送通过 INT发送中断信号给 AP, 来实时检测电池 电量, 并提示电池电量低或者关机等信息, 优化用户的使用体验。
综上, 本发明实施例中通过在三种不同的工作状态下采用三种不同唤 醒机制的技术方案, 来完成各种情况下手机与基站交互和手机状态检测, 避免单一的方式引起的待机电流的增大。 该方案可以根据不同状态特点优 化待机电流, 从而达到减小待机电流, 增强电池续航能力的目的。
具体的, 本发明实施例中提供了一种电量检测电路, 用以确定手机电 池的电量高低, 并将电量的高低作为在手机唤醒退出手机待机模式后的处 理依据之一; 本发明实施例中还提供了一种包括这种电量检测电路的手机 待机时手机状态检测的处理装置, 用以处理手机待机时手机状态检测的流 程, 来提高手机的待机时间。
相应的, 基于同一发明构思, 本发明实施例中还提供了一种手机待机 时手机状态检测的处理方法, 用以处理手机待机时手机状态检测的流程, 来实现提高手机的待机时间。
下面结合附图对本发明的具体实施方式进行说明。
图 1 为手机待机时手机状态检测的处理装置结构示意图, 如图所示, 装置中包括电量检测电路 101、 AP模块 102、 Modem模块 103 , 下面现对 电量检测电路的实施方式进行说明, 然后对处理装置的实施方式进行说明。
如图所示, 在电量检测电路 101中, 可以包括:
电池 1011 , 电池的正极与 AP模块的模数转换端口 (Analog-Digital Converter , ADC )相连, 电池的负极在依次串联第一电阻 R1、 第二电阻 电压比较器 1012, 与电池的负极相连, 用于根据第一电阻 Rl、 第二电 阻 R2、 第三电阻 R3值确定电量上限值、 电量下限值, 并才艮据电量上限值、 电量下限值检测电池的电量是否为低。
实施中, 电压比较器 1012中可以包括:
输入端 10121 , 在第一电阻 R1与第二电阻 R2之间输入电量上限值, 在第二电阻 R2 与第三电阻 R3 之间输入电量下限值, 所述电量上限值为 1.240 (R1+R2+R3)/(R2+R3), 电量下限值为 1.240 (Rl+R2+R3)/R3;
实施中, 输入端的结构关系是: 输入端 10121在第一电阻 R1与第二电 阻 R2之间, 从该处输入电量上限值, 在第二电阻 R2与第三电阻 R3之间, 从该处输入电量下限值。
比较单元 10122, 用于在确定电池的电量在电量上限值、 电量下限值之 间时确定电量为低, 在确定电池的电量不在电量上限值、 电量下限值之间 时确定电量为高。
实施中, 比较单元还可以进一步用于在电量为低时通过输出端发送中 断信号;
则在电压比较器中还可以进一步包括:
输出端 10123 , 与 AP模块的 INT相连, 用于传输来自比较单元的中断 信号。
具体实施中, 电压比较器可以用精密电压比较器件来实现, 这样在通 过 Rl、 R2、 R3 以及精密电压比较器件组成的低电压检测电路来通过 INT 发送表示电池电量低的中断信号, 从而可以检测出手机是否处于低电状态。 图中, VoH为低电量的上限值, VoL为低电量的下限值, 则可以通过 Rl、 R2、 R3三个电阻值利用电压比较器提供的计算公式来确定电池电量为低的 范围, 具体的公式可以是:
VoL= 1.240(R1 +R2+R3 )/(R2+R3 );
VoH= 1.240(R1 +R2+R3 )/R3。 实施中,可以通过硬件来确定电池低电的范围,即 VoL和 VoH的取值。 例如: 当 BAT+ (电池) 的电量达到 VoL~VoH范围时 (比如 Rl、 R2、 R3 取值分别为 121Kohm、 1.8Kohm、 68Kohm,设定 VoL为 3.40, VoH为 3.49V, 则 BAT+为 3.30~3.49V时,电池为低电状态 ),精密电压比较器 D1通过 INT 输出低电平中断信号,从而可以触发 AP模块启动低电量的手机状态检测处 理程序。
实施中, 在包括了电量检测电路 101 的待机时手机状态检测的处理装 置中还可以包括 AP模块 102、 Modem模块 103 , 则如图所示, 其结构关系 可以是:
电量检测电路 101 , 与 AP模块的 INT相连, 用于发送中断信号; AP模块 102,与 Modem模块通过数据接口相连,用于在收到中断信号 后根据中断信号确定电池电量为低;在电池电量为高时向 Modem模块发送 命令, 且通过 Modem模块对所述命令的响应来确定 Modem模块的工作状 态; 并根据手机电池电量与 Modem模块的工作状态确定唤醒后续流程; Modem模块 103 ,用于在处于工作状态时,对 AP模块的命令进行响应。 具体实施中, 手机待机时手机状态检测的处理装置主要由低电检测电 路、 AP模块和 Modem模块组成。 其中低电检测电路通过 ADC转换接口和 中断接口和 AP模块相连, Modem模块通过数据接口和 AP相模块连, 和 普通的智能机硬件相比, 主要增加了低电量检测电路。 通过将电池 BAT+ 连接到 AP模块的模数转换端口 (ADC ), 并用来检测正常情况下的手机电 池电量, 通过定时唤醒 AP模块来获得电池电量的值。
Modem和 AP之间则可以通过数据接口来判断 Modem是否打开,例如 AP模块向 Modem模块发送 READY命令, Modem模块返回命令 OK时, 便可以表示 Modem模块是打开的, 便可以执行 Modem模块打开时的唤醒 机制, 如果 Modem模块没有 OK返回, 则表示 Modem模块未打开, 程序 执行 Modem模块未打开的唤醒机制。 这样便可以通过判断是否低电, 然后 判断 Modem模块是否打开来分开三种状态, 采取三种不同唤醒机制, 从而 达到减小待机电流目的。
具体的, AP模块可以进一步用于在根据手机电池电量与 Modem模块 的工作状态确定唤醒后续流程时, 确定手机电池电量为低时, 唤醒后续流 程为定时检测手机状态; 确定手机电池电量为高, Modem模块在工作状态 时, 唤醒后续流程为定时与基站交互和检测手机状态; 确定手机电池电量 为高, Modem模块不在工作状态时, 唤醒后续流程为定时检测手机状态。
实施中, 定时检测手机状态可以包括实时检测电池电量及温度。
基于同一发明构思, 本发明实施例中还提供了一种待机时手机状态检 测的处理方法, 由于该方法解决问题的原理与待机时手机状态检测的处理 装置相似, 因此该方法的实施可以参见处理装置的实施, 重复之处不在赘 述。
图 2为待机时手机状态检测的处理方法实施流程示意图, 如图所示, 可以包括如下步骤:
步骤 201、 手机待机时, 根据电量检测电路确定手机电池电量高低; 步骤 202、 在手机电池电量为高时, 确定 Modem模块的工作状态; 步骤 203、 根据手机电池电量高低与 Modem模块的工作状态确定唤醒 后续流程。
实施中, 在确定手机电池电量高低时, 可以包括:
将电池的正极与 AP模块的 ADC相连, 电池的负极在依次串联第一电 阻、 第二电阻、 第三电阻后接地;
将电压比较器与电池的负极相连, 与 AP模块的 INT相连, 根据第一 电阻、 第二电阻、 第三电阻值确定电量上限值、 电量下限值, 并根据电量 上限值、 电量下限值检测电池的电量是否为低。 实施中, 在根据第一电阻、 第二电阻、 第三电阻值确定电量上限值、 电量下限值, 并根据电量上限值、 电量下限值检测电池的电量是否为低时, 可以包括:
在第一电阻与第二电阻之间向电压比较器输入电量上限值, 在第二电 阻与第三电阻之间向电压比较器输入电量下限值, 所述电量上限值为 1.240 (R1+R2+R3)/(R2+R3), 电量下限值为 1.240 (Rl+R2+R3)/R3;
在确定电池的电量在电量上限值、 电量下限值之间时确定电量为低, 在确定电池的电量不在电量上限值、 电量下限值之间时确定电量为高。
实施中, 在确定手机电池电量高低时, 可以包括:
在电压比较器确定电量为低时, 向 AP模块发送中断信号;
AP模块在接收到中断信号后, 确定电池电量为低。
实施中,在根据手机电池电量与 Modem模块的工作状态确定唤醒后续 流程时, 可以包括:
确定手机电池电量为低时, 唤醒后续流程为定时检测手机状态; 确定手机电池电量为高, Modem模块在工作状态时, 唤醒后续流程为 定时与基站交互和检测手机状态;
确定手机电池电量为高, Modem模块不在工作状态时, 唤醒后续流程 为定时检测手机状态。
实施中, 定时检测手机状态可以包括实时检测电池电量及温度。
为了更好的说明本发明实施例中的技术方案, 下面再举实例进行说明。 图 3 为待机时手机状态检测的处理实施流程示意图, 如图所示, 可以 包括如下步骤:
步骤 301、 进行电池电量检测。
步骤 302、 判断电量是否为低, 如果是, 则转入步骤 303; 否则, 转入 步骤 304。 具体实施中, 在电池电量为低时, 可以发送中断信号给 AP模块, 从而 使 AP模块知晓电量的高低状态。
步骤 303、 实时检测电量及温度, 避免用户不良体验, 流程结束。 步骤 304、 判断 Modem模块是否在工作, 如果是, 则转入步骤 305; 否则, 转入步骤 306。
步骤 305、 采用一般终端唤醒策略, 定时与基站交互和检测手机状态。 步骤 306、 手机不与基站交互, 定时 (如 10分钟)检测手机状态。 在上述实施中, 开机后执行步骤 301 , 开始启动电池电量检测, 首先在 步骤 302判断是否为低电状态, 如果是, 则采用步骤 303的实时检测手机 状态 (例如电池电量、 温度等) 的唤醒机制, 硬件电路在电量低时会产生 中断信号, 可以根据该信号实时发送电量低或者关机的提示信息, 优化用 户的使用体验; 如果否则进入步骤 304的操作。
在步骤 304 中, AP模块可以通过数据接口发送命令 READY, 如果 Modem模块返回 OK, 则可以判断 Modem模块处于打开的工作状态, 此时 可以采取步骤 305 中的一般终端的唤醒机制。 该方案会定时唤醒, 退出待 机状态来完成手机与基站的交互, 并在手机与基站交互的 burst间隙时间来 检测手机状态(例如电池电量、 温度等), 这种情况下待机电流保证和一般 终端耗电一致; 如果 Modem模块没打开, 则进入步骤 306操作。
如果 AP模块通过数据接口发送命令 READY,而 Modem模块没有 OK 返回, 则可以判定 Modem模块没打开, 即不在工作状态, 此时, 可以采用 步骤 306 中的手机与基站不需要交互的唤醒机制, 实施中只需要进行手机 状态的检测。 可以通过拉长手机状态 (例如电池电量、 温度等)检测的间 隔, 例如可以每 10分钟左右定时检测一次手机状态(例如电池电量、 温度 等)或者在该状态下不需要检测手机状态。 对比一般终端的唤醒机制几十 ms就需要唤醒一次的频率, 可以大大减少唤醒次数, 从而减少电流消耗, 增加待机时间。
由上述实施例可知, 本发明实施例中提供的技术方案可以根据不同的 工作模式来采用不同的唤醒机制, 完成手机与基站交互和手机状态检测, 从而避免单一的唤醒方案引起的待机电流增大的问题, 达到增加待机时间 , 增强电池续航能力的目的; 同时对于低电的状态采用硬件检测方式, 可以 保证在低电状态可以输出低电告警和关机信息, 而不会发生自动关机的情 况, 减少用户不良体验。
