The second control switch is in one-to-one correspondence with the first control switch; one end of the second control switch is connected to the detecting unit 300, and the other end is connected to a signal input interface of the television;
当所述检测单元300检测到所述第一开关控制单元200中有两个或两个以上第一控制开关导通时，所述检测单元300向所述第二开关控制单元400中与导通的第一控制开关对应的第二控制 开关中的部分第二控制开关输出低电平信号，使得该部分第二控制开关打开，以保证只有一个接口与电视的信号输入接口相连。When the detecting unit 300 detects that two or more first control switches are turned on in the first switch control unit 200, the detecting unit 300 is turned on and turned on in the second switch control unit 400. The second control corresponding to the second control switch A portion of the second control switch in the switch outputs a low level signal such that the portion of the second control switch is turned on to ensure that only one interface is coupled to the signal input interface of the television.
具体地，所述检测单元300可以由处理器以及与第一控制开关数量相同的电流/电压检测电路实现。Specifically, the detecting unit 300 may be implemented by a processor and a current/voltage detecting circuit having the same number as the first control switch.
