Description

一种移动终端USB或充电器插入识别方法及识别装置
技术领域
本发明涉及移动通信终端领域，特别涉及一种USB或充电器插入识别电路。
背景技术
随着2007年新国标充电器《移动通信手持机充电器及接口技术要求和测试方法》的推行，国内手机充电器已经实现了统一。新国标中规定充电电缆线充电器测插头采用USB A系列插头，手机测插头不做强制要求。
但随着全社会环保节能意识的不断深化，大部分终端厂家在设计充电电缆时，开始逐步倾向采用通用的mini USB& USB A系列USB电缆线。手机采用该通用USB电缆线来作为充电与数据线将实现成本、节能环保等社会效益的最大化。
当用户采用该通用USB线来进行充电器充电或USB充电或者是USB数据传输时，手机将进行插入连接的是充电器还是电脑的判断动作。当前各终端厂家及上游开发平台采用的插入判断方法五花八门，有的判断准确但方法复杂，有的方法简单但容易误判。
常规的判断思路：如图1所示为新国标充电器的接口示意图，图中左边接口为50Hz 220Vac市电输入，右边接口为充电器5V直流输出端，可以看到充电器输出的D－与D＋接口是短路连接的。因此，所有的充电器或电脑USB插入判断基本都是围绕该特点进行，即当插入的是充电器时手机检测到D－与D+电压相同因此判断是充电器插入，当插入的是电脑USB时手机检测到D－与D+电压不同因此判断为电脑USB插入。
但是，现有技术还会出现一种误判缺陷：一般标准的USB mini端及A端插头里USB的数据D＋、D－引脚都短于5V和GND的引脚。当手机插入充电器时，不论是mini端插手机或A端插充电器，只要用户插入动作速度很慢或只插入一半不全插入时，手机就会判断是USB插入并进入USB模式。一旦手机进入USB模式后，就算充电插头之后再完全插入，手机也不会重新回到充电器模式。原因是很多终端厂家或开发平台，必需要进行拔出判断后才进行下一次插入动作的判断。因此不同的充电器插入动作速度会使手机进入不同的充电状态，插入动作快的就会进入充电器充电模式，插入动作慢就会进入USB模式。根本原因是很多设计没有全面的考虑到USB线的mini端和A端里的D＋、D－引脚与5V、GND的引脚长度不一致和用户的实际操作情况有差异，而导致误判。
因而，现有技术还有待改进和提高。

本发明实施例1所提供的一种移动终端USB或充电器插入识别装置，其原理，如图2所示，当移动终端的接口检测和控制模块110检测到有外部供电装置（电脑USB线或标准充电器）接入USB接口模块110时，接口检测和控制模块120初始化，并输出第一控制信号控制电子开关模块140与基带USB数据收发模块160连接，优先进入USB模式；
优先进入USB模式后，如果此时识别模块150检测充电切换模块140输出状态未发生变化时，即此时识别模块150检测充电切换模块140输出的状态与接口检测和控制模块120初始化时，充电切换模块140输出的状态一样，则前接入的供电装置为计算机的USB A系列接口；
当识别模块150检测充电切换模块140输出状态发生变化时：如果此时，通过接口检测和控制模块120检测USB接口模块的D-端信号状态不再发生变化，则接口检测和控制模块120产生中断并输出第二控制信号控制所述电子开关模块与充电切换模块连接，进入充电器工作模式，则当前接入的供电装置为标准充电器；否则，当前接入的供电装置为非标准充电器。
以下结合图3详细说明上述各个部分在具体实现时的电路结构形式：
本发明实施例所提供的移动终端USB或充电器插入识别装置，如图3所示，USB接口模块110包括：5V电源输入端ADAPTER_OR_USB_INPUT即V Bus，D－输入端USB_D-_IPPUT，D＋输入端USB_D+_INPUT。
所述电子开关模块130为一型号为FSUB30L10的集成芯片U55，所述FSUB30L10集成芯片的第1脚S控制端与所述接口检测和控制模块的BASEBAND_GPIO_CONTROL端相连，第9脚/OE端、第8脚HSD2-端和第5脚GND端接参考地，第4脚与USB接口模块的D+端USB_D+_INPUT相连，第6与USB接口模块的D-端USB_D-_IPPUT相连，第3脚HSD2+和第7脚HSD2-端分别通过USB_D+_TO_BASEBAND端和USB_D-_TO_BASEBAND与所述基带USB数据收发模块160相连。
所述充电切换模块140包括一型号为SI8415DB的场效应管，所述SI8415DB场效应管的S极通过一电阻R598与所述FSUB30L10集成芯片的第2脚HSD1+端相连，所述SI8415DB场效应管的两D极与所述识别模块和充电模块相连，所述SI8415DB场效应管的G极通过电阻R11和电阻R590连接参考地。
接口检测和控制模块120包括与D－输入端USB_D-_IPPUT连接的接口检测端（图中示标出），以及与所述FSUB30L10集成芯片的第1脚S控制端相连的BASEBAND_GPIO_CONTROL控制端。
所述识别模块150包括BASERAND_USB_DETECT端和BASERAND_ADAPTER_DETECT。
在终端系统中，有的GPIO在有充电电源插入的情况下，不论插入的是充电器或USB，不论手机开机与否，该GPIO在完成初始化之后将置位为高电平。本发明实施例所提供的移动终端USB或充电器插入识别装置，采用这样的GPIO（即图中接口检测和控制模块的BASEBAND_GPIO_CONTROL控制端）来与U55的“S”引脚相连，将“/OE”引脚直接接地，如图3所示。其中，所述FSUB30L10集成芯片U55的控制逻辑为当“S”和“/OE”都为低电平时D＋、D－与HSD1＋、HSD1－连通，当“S”为高电平和“/OE”为低电平时D＋、D－与HSD2＋、HSD2－连通。
当移动终端的接口检测和控制模块110检测到有外部供电装置（电脑USB线或标准充电器）接入USB接口模块110时，接口检测和控制模块初始化，其BASEBAND_GPIO_CONTROL控制端（GPIO）输出第一控制信号为高电平，使终端系统内的USB D+（HSD2＋）、D－（HSD2－）与接口的D＋、D－相连，为终端进入USB模式创造物理连接通道。如此时插入的是USB，识别模块150的baseband_USB_detect端将检测到高电平，baseband_adapter_detect 端将检测为低电平，终端可以此作为USB插入的判断，产生USB插入中断响应，进入USB模式；如此时插入的是充电器，因充电器接口的D＋和D－是短路连接的，D＋信号在终端基带内是上拉到3.3V，因此D－信号也会被上拉到3.3V，此时终端的接口检测和控制模块120通过检测D－信号的变化产生中断响应，接口检测和控制模块的BASEBAND_GPIO_CONTROL控制端（GPIO）输出第二控制信号为低电平信号，即将与U55的“S”引脚相连的GPIO（即图中的BASEBAND_GPIO_CONTROL控制端）置为低电平，使终端系统内的USB D+（HSD2＋）、D－（HSD2－）与接口的D＋、D－的连接断开，从而断开终端基带USB数据收发模块的USB信号与外部的连接，并将U55的HSD1＋、HSD1－引脚与充电器接口的D＋、D－相连，此时HSD1＋被拉到低电平，从而使充电切换模块中的U54场效应管打开，此时图3中充电切换模块输出的一识别信号 “baseband_adapter_detect”变成了高电平，终端识别模块检测到“baseband_adapter_detect”和“baseband_USB_detect”同时为高电平时启动二次中断进入充电器工作模式。
以上即为完整的充电器或USB插入判断过程，通过硬件使终端在有外部电源插入时优先进入USB模式，而根据最终检测的D－信号状态可灵活产生中断响应，对USB或充电器插入进行准确的判断。
基于上述识别装置原理及图2和图3所示的电路，本发明的一种移动终端USB或充电器插入识别方法，其流程图如图4所示，包括步骤：
步骤210、当移动终端的接口检测和控制模块检测到有外部供电装置接入USB接口模块时，接口检测和控制模块初始化，并输出第一控制信号控制电子开关模块与基带USB数据收发模块连接，进入USB模式；
步骤220、识别模块检测充电切换模块输出状态是否发生变化，如果发生变化，则执行步骤240；否则，则执行步骤230；
步骤230、当前接入的供电装置为计算机的USB A系列接口；
步骤240、接口检测和控制模块检测USB接口模块的D-端信号状态是否发生变化，如果发生变化，则执行步骤260；否则，则执行步骤250；
步骤250、则接口检测和控制模块产生中断并输出第二控制信号控制所述电子开关模块与充电切换模块连接，进入充电器工作模式，则当前接入的供电装置为标准充电器；
步骤260、当前接入的供电装置为非标准充电器。
综上所述，本发明提供的移动终端USB或充电器插入识别方法及识别装置，该识别装置使终端在有外部电源插入时优先进入USB模式，而根据最终检测的D－信号状态可灵活产生中断响应，对USB或充电器插入进行准确的判断，其能快速准确地识别终端插入的USB或充电器的类型。
