技术领域
本发明涉及移动终端领域,尤其涉及的是一种移动终端及OTG控制配置方法、及存储介质。
背景技术
OTG是On-The-Go的英文缩写,是近几年来发展起来并广泛使用的一项技术。2001年12月OTG技术由usb implementers forum发布,主要应用于各种不同的设备或移动终端设备之间的连接,以及数据交换。随着OTG等技术的发展,移动终端可以通过OTG技术为连接到其上的U盘等设备供电并进行文件复制等常用操作,移动终端也可以通过OTG技术为连接到其上的鼠标等设备供电并获取鼠标的轨迹。
目前,只要移动终端与OTG外设进行连接,便会由移动终端为OTG外设进行自动充电,而在移动终端与OTG外设进行关键操作时,在线上可能有大量的数据在进行高速传输,或数据量较小但操作极其关键,需要保持线上电压的稳定,而由于移动终端为OTG外设充电过程中电流会随时变化,导致线上电压也会出现变化,从而电流变化对OTG操作造成干扰。当所执行的操作不关键时,可以通过重新发送操作内容来进行修复,但如果是关键操作(如U盘格式化等)则会使OTG外设死机,给用户造成不便。
因此,现有技术存在缺陷,有待改进与发展。

图3是本发明实施例提供的移动终端的又一功能原理框图。
图4是本发明实施例提供的移动终端的结构示意图。
本发明的实施方式
为使本发明的目的、技术方案及优点更加清楚、明确,以下参照附图并举实施例对本发明进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
请参见图1,图1是本发明实施例提供的移动终端OTG控制配置方法的流程图。如图1所示,本发明实施例所述移动终端OTG控制配置方法,包括以下步骤:
步骤S100、每隔一段时间获取OTG数据线上的数据正极线、数据负极线电压差的累计变化次数。
本发明实施例在具体实施前需要,预先在移动终端例如手机上设置OTG线上数据正极线(DP)、数据负极线(DM)电压差的变化次数与OTG线上电流的对应关系,生成与OTG线上数据正极线、数据负极线电压差变化次数对应的查询表。
例如本发明中设置:
一秒变化100至300次则对应的电流是300毫安(mA);
一秒变化300次以上则对应的电流是200毫安(mA);
一秒变化100次以下则对应的电流是500毫安(mA)。
其中,所述每隔一段时间获取OTG线上的数据正极线与数据负极线电压差的变化次数包括:例如,设置一定时器,每隔一段时间(例如1秒)获取OTG线上数据正极线的电压、数据负极线电压;
计算所述数据正极线的电压、数据负极线电压之差;
判断本次计算的数据正极线的电压、数据负极线电压之差与前一次计算的数据正极线的电压、数据负极线电压之差相比是否大于阈值,若为是则认为OTG线上数据正极线、数据负极线电压差变化了一次。
本发明实施例中所述阈值可以为50毫伏(mV)。具体地,判断本次计算的数据正极线的电压、与前一次计算的数据正极线的电压之差相比是否大于50毫伏的阈值,若为是则认为OTG线上数据正极线电压差变化了一次。
当负极线的电压、与前一次计算的数据负极线的电压之差相比大于阈值(例如50毫伏),则认为OTG线上数据负极线电压差变化了一次;
并将OTG线上数据正极线和数据负极线电压差的变化依次累计叠加通过同一计数器记录保存。
步骤S200、根据OTG线上获取OTG线上数据正极线、数据负极线电压差的累计变化次数,在预先存储在移动终端中的查询表中查询所述变化次数对应的电流。
本发明中,所述根据OTG线上获取OTG线上数据正极线、数据负极线电压差的累计变化次数,在预先存储在移动终端中的查询表中查询所述变化次数对应的电流包括:获取OTG线上数据正极线、数据负极线电压差的累计变化次数;
根据OTG线上获取OTG线上数据正极线、数据负极线电压差的累计变化次数,在预先存储在移动终端中的查询表中查询所述变化次数对应的电流。
例如查上表:
一秒变化100至300次则对应的电流是300毫安(mA);
一秒变化300次以上则对应的电流是200毫安(mA);
一秒变化100次以下则对应的电流是500毫安(mA)。
步骤S300、根据查询到的对应的电流,控制移动终端对OTG外设设置电流限制为所述对应的电流。
本步骤中,会获取查询到的对应的电流;根据查询到的对应的电流,控制移动终端对OTG外设设置电流限制为对应的电流。
例如,接上所述,当查询到一秒变化100至300次,则控制移动终端对OTG外设设置电流限制为300毫安(mA);
当查询到一秒变化300次以上,则控制移动终端对OTG外设设置电流限制为200毫安(mA);
当查询到一秒变化100次以下,则控制移动终端对OTG外设设置电流限制为500毫安(mA)。
由上可见,本发明提供了一种移动终端OTG控制配置方法,可以当移动终端通过OTG与外设进行连接时,使移动终端为OTG外设充电的同时保证线上电压的稳定,使移动终端对OTG外设的关键操作指令能够顺利送达。
