Abstract

The invention relates to a USB (Universal Serial Bus) interface multiplexing interphone and a control method thereof; the interphone comprises an USB interface, an interface detection module, a control module and at least two function processing modules which are arranged on the interphone, wherein the interface detection module is used for detecting whether a signal detection pin on the USB interface of the interphone is effective and generating a pin detection signal; the control module is used for judging whether the USB interface on the interphone is connected into an exterior plug-in unit according to the pin detection signal and the type of the exterior plug-in unit when the USB interface is connected into the exterior plug-in unit; and the control module is also used for controlling the functional processing modules in the interphone corresponding to the type of the exterior plug-in unit to be communicated with the exterior plug-in unit according to the judgment result of the type of the exterior plug-in unit. The USB interface of the interphone provided by the invention can be applied to USB channel transmission equipment, plug-in modules of headsets and the like; and the multiple functional interfaces are multiplexed on the interface with very small size, thereby the volume of the interphone is reduced, and the USB (Universal Serial Bus) interface is very suitable for the small-sized portable interphone and has very obvious cost advantage.

Description

technical field [0001] The invention relates to the technical field of communication, and more specifically, to a walkie-talkie with multiplexed USB interfaces and a control method thereof. Background technique [0002] The design of walkie-talkies is becoming increasingly compact, light and integrated. However, due to the various data transmission functions that the walkie-talkie has, there are many interfaces on the casing, such as a USB interface and an earphone interface. These interfaces occupy a large space and are expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a walkie-talkie with multiplexed USB interfaces and a control method thereof, aiming at the defect that too many interfaces of the existing walkie-talkie occupy a large space. [0004] The technical solution adopted by the present invention to solve the technical problem is to construct a walkie-talkie with multiplexed USB interfaces, i...
