Novel multi-interface multiplexing device and control method

The invention relates to the technical field of electronic information, in particular to a novel multi-interface multiplexing device and a control method. Comprising a control module, a conversion module and external interface modules, the control module judges which type of data to be received is based on a received setting instruction and sends a control signal to the conversion module to indicate to conduct the data type, and the conversion module is communicated with different external interface modules on a hardware circuit based on indication of the control signal; the external interface module performs transparent transmission on a hardware channel established based on the conversion module, and the device realizes transmission of various interface data on the same physical interface through special circuit design and software control, and achieves the effect of multi-interface multiplexing, thereby saving physical interfaces, meeting the product function requirements under the condition of resource li
