Description

移动终端及其电源管理方法 技术领域
本发明涉及一种移动终端及其电源管理方法，尤其涉及一种适用于多模移动通信手机及其低电量管理方法。
 背景技术
随着通信科技的发展，移动通信手机已被人们广泛应用于日常生活和学习中，人们通过移动通信手机和网络通话或互发短信息，其不但大大拉近了人们彼此之间的距离，还给人们的联系和信息交流带来了极大的便利。目前的移动通信网络主要包括GSM、GPRS、WCDMA、CDMA、CDMA1X、CDMA2000、TD－SCDMA，PHS、WIFI等，支持上述一种或多种通信网络（多模通信终端）的手机也日新月异。
现有的多模移动终端（如中国第200510024476.X号专利所揭示的一种双模/多模便携装置及其智能切换方法）可实现使用多个网络的服务，但其通常只能是通过用户选择其中一个网络的通信模块处于工作状态，另一网络的通信模块处于关闭状态，当手机电源处于低电状态（电量低到一定程度，工作电压达到临界范围内）时，电量检测模块就会报警并直接关闭手机。然而，上述现有技术的电源管理方法过于简单，其低电状态是根据整个手机的功耗水平来设定的，一旦关机即导致手机上的所有应用功能无法使用，不能充分利用电池的剩余电量。
 技术问题
为了克服现有移动终端的电源管理方法简单、不能充分利用电池电量的不足, 本发明提供一种移动终端及其电源管理方法，其可有效利用电池电量。
 技术解决方案

所述优先级是根据各通信模块和功能模块的功耗水平从高到低依次划分。
所述优先级是根据用户的需求自行设定各通信模块和功能模块的关闭次序。
所述电阈值是电流值或电压值。
所述移动终端包括两种或两种以上通信模块，所述步骤C还包括根据电源电量下降的水平逐步关闭每一通信模块的步骤。
为解决上述另一技术问题，本发明所采用的技术方案是：提供一种移动终端，其包括CPU，分别与CPU连接的多个通信模块和功能模块、电源模块、电源检测模块，所述移动终端还包括一与CPU连接的多级电源管理模块，用于将上述电源电量分成多个级别，并对应每一级别设置一电阈值。
所述电源检测模块是电流检测模块或电压检测模块。
所述移动终端是多模移动终端，包括两种或两种以上通信模块，每一通信模块中均包含一电源管理单元，当电源处于低电状态时，根据电量下降的水平依次逐步关闭每一通信模块。
所述移动终端还包括一与CPU连接的优先级设定模块，用于根据用户需求自行设定各通信模块和功能模块的关闭次序。
所述移动终端还包括一与CPU连接的低压报警模块，用于通过图形、文字或声音警示用户。
 有益效果
本发明的有益效果在于：由于本发明移动终端及其电源管理方法通过根据移动终端的多个通信模块或功能模块功耗水平将电源电量划分成多个级别，并分级进行电阈值对比关闭处理，可实现有效利用电池电量。
 附图说明
图1是本发明移动终端的电源管理方法的流程示意图；
图2是本发明移动终端的电源管理相关部分的示意图；
图3是本发明移动终端的电源管理方法一实施例的过程示意图。
 本发明的实施方式
由于移动终端的功能模块越来越多，尤其是在多模移动终端中，设备的功耗比较大，本发明移动终端的电源管理方法为了有效的利用电池电量，对电池的低电状态采用了更加高效的分级处理，随着电池电量的降低，逐步关闭设备。
请参阅图1，本发明移动终端的电源管理方法包括以下步骤：
根据移动终端的各通信模块和功能模块的功耗从高到低将电源电量划分成多个级别；
对应每个级别分别设置一电阈值；
判断移动终端待机或工作时的电源是否低于任一电阈值时，若低于则根据优先级相应关闭此级别阈值所对应的通信模块或功能模块。
上述优先级是根据各通信模块和功能模块的功耗水平从高到低依次划分或是根据用户的需求自行设定各通信模块和功能模块的关闭次序。
可以理解，本发明移动终端的电源管理方法的电阈值可为电流值或电压值。
请一并参阅图2，本发明移动终端包括CPU、多个通信模块和功能模块、多级电源管理模块、电源模块以及电源检测模块（本实施例为电流检测模块，同时也可为电压检测单元），移动终端制造商或用户通过多级电源管理模块根据多个通信模块和功能模块的功耗水平将电源电量分成多个级别，并对应每一级别相应设定一电阈值，当多模移动终端处于待机或工作状态时，电源检测模块不断检测电源模块的剩余电量，当电源模块处于高电量状态时，所有通信模块和功能模块均正常工作。当发现电源模块处于低电状态时，判断剩余电量是否低于最高级别的电阈值，若低于则关闭该级别对应的功耗较大的通信模块或功能模块，剩余模块正常工作；再判断剩余电量是否低于次高级别的电量阈值，若低于则关闭该级别对应的通信模块或功能模块，剩余模块正常工作；依次直至完全关闭移动移动终端。同时，所述移动终端还可包括一与CPU连接的优先级设定模块（图未示），用于根据用户需求自行设定各通信模块和功能模块的关闭次序，当电源剩余电量低于某一设定电阈值时，系统将关闭用户所选定的通信模块或功能模块。
请一并参阅图3，采用本发明移动终端的电源管理方法的多模移动终端的一实施例电量管理模式包括以下步骤：处于待机状态或工作状态时，检测电量或电压是否到达临界；若到达临界值，则通过一低压报警模块（图未示）发出图形、文字或声音等低压报警信号警示用户，并关闭一个通信模块，同时降低其他设备的功耗；当电源电量或电压降到更低的水平，继续关闭其他通信模块；当电源电量或电压降到最低的水平，关闭手机。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围，凡在本发明的精神和原则之内所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
