However, in the USB direct connection mode, when the main control chip SOC of the TV is in the standby mode, the d+ of the Device end of the wireless communication module adapted to the SOC has a voltage of 3.3V, and the HOST end of the main control chip is powered down in the standby state, i.e. d+ and D-of the HOST end are both 0V, so that there is a problem of leakage. When the Device detects that the voltage of d+ is not 3.3V, the Device exits the sleep mode, resulting in higher standby power consumption.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the HOST end of the main control chip SOC of the existing TV is directly connected to the Device end of the wireless communication module through a USB, and d+ and D-of the USB are connected to d+ and D-of the Device end respectively. The Device terminal has a voltage of 3.3V.
According to the method and the device, on the basis of an existing scheme, a DPDT switch is added, the DPDT switch is provided with two paths of inputs, and each path of input corresponds to two paths of output. As shown in fig. 2, a first data end d+ of the wireless communication module Device is connected to a first input end of the DPDT switch, the first input end of the DPDT switch corresponds to a first output end d1+ and a second output end d2+ of the DPDT switch, a second data end D-of the wireless communication module is connected to a second input end of the DPDT switch, and the second input end of the DPDT switch corresponds to a third output end D1-and a fourth output end D2-of the DPDT switch;
