优选的，通过母数据接口上的ID引脚检测接入该母数据接口的数据线为OTG数据线还是普通的USB数据线，当母数据接口上的ID脚接地时，默认为OTG数据线接入，当母数据接口上的ID脚悬空时，默认为USB数据线接入，从而，智能终端可以通过接入的数据线的类型判断其作为待充电设备，还是为配件扩展连接器提供驱动电压的供电设备使用。当充电设备处于数据传输状态时，可以通过应用软件设置电子开关的使能控制端为低电平，使得OTG上的两个标准数据线与处理器上的USB信号连接，当充电设备处于OTG反向供电状态时，通过软件设置使能控制端为高电平，此时，OTG的两条数据线和两个短接端连接，处于短接状态，母数据接口只提供电源线和地线，母数据接口即可作为标准充电器接口使用，实现为配件扩展连接器反向电流供电。
S130将获取的控制指令发送至所述配件扩展连接器，以便所述配件扩展连接器控制所连接的功能配件执行对应操作。
本发明通过智能终端连接配件扩展连接器，使智能终端不仅仅为用户提供智能终端本身具有的服务功能，还可以通过配件扩展连接器将智能终端的无线通信、信号处理等能力更加充分地利用起来，一方面很大程度上扩展了智能终端的功能，丰富其差异化，使智能终端产品更具有市场竞争力，另一方面，使用智能终端作为可编程硬件的主机，可以实现一机多用，能够有效降低各种可编程的智能终端的成本，同时也使得可编程智能终端具有更强的可扩展性。
