Description

一种实现连接控制的方法及装置 技术领域
本文涉及电子控制技术，尤指一种实现连接控制的方法及装置。
背景技术
移动终端的充电技术在不断发展，充电需求变得日益简单化、快捷化、多样化，无线充电技术在需求下产生。无线充电源于无线电力输送技术，又称作感应充电，通过电感耦合，由供电设备(充电器)将能量传送至用电装置进行电池充电。由于供电设备与用电装置通过电感耦合进行能量传送，因此，无需有线连接，供电设备及用电装置均可实现无导电接触点外露。
无线充电时，用电装置的接收器通过将交流信号转换为5V直流信号后进行充电，与标准充电器(有线充电器)不同，输出信号仅为电源线和地线。市场上大多数用电装置的充电管理器将只有电源线和地线的充电器默认为连接电脑进入USB模式，而此模式只能提供小于或等于500mA的充电电流(例如450mA)，加上系统消耗，实际进行电池充电的电流只有400mA左右，而400mA左右进行电池充电，其充电过程十分缓慢。因此，将无线充电默认为连接电脑进行通用串行总线(USB)模式，充电缓慢，无法满足用户进行充电的需求，影响无线充电技术的应用。
为了提高无线充电的效率，大多数带无线充电功能的用电装置通过在有线充电和无线充电进入不同的充电管理器；有线充电与无线充电都设置相应的充电管理器，增加了用电装置的成本和印制电路板(PCB)布局。若使用一个充电管理器，由于充电管理器已经完成充电类型的枚举，将无线充电配置为AC充电，这样，在无线充电时连接电脑或OTG设备，是无法识别出电脑或OTG设备的；而如果截止无线充电后，在中断USB连接或移除OTG设备后，由于无线充电通讯断链，无线充电无法恢复，即由于无线充电截止，充电管理器进行了充电类型的枚举，因此还是无法识别出USB连接中断或OTG设备移除。
综上，采用两个充电管理器的方法，在成本和PCB布局上都将对用电装置造成很大影响，不利于用电装置的应用；采用一个充电管理器的方法，在完成无线充电枚举之后，将无法识别连接电脑或OTG设备；在完成连接电脑或OTG设备的枚举之后，将无法识别USB连接中断或OTG设备移除，因此也无法进行无线充电。
