Abstract

The embodiment of the invention relates to equipment identification method and device, wherein the method comprises the following steps: adjusting a first resistance corresponding to a first voltage level and a second resistance corresponding to a second voltage level; acquiring a first voltage value corresponding to the first voltage level and a second voltage value corresponding to the second voltage level; and determining externally connected equipment pattern according to the first voltage value and the second voltage value. The equipment identification method and device provided by the embodiment of the invention determine the externally connected equipment pattern solely depending on the first voltage value corresponding to the first voltage level and the second voltage value corresponding to the second voltage level. Because the method can be realized inside a driver integrated circuit without specially setting an externally connected selector switch, the invention reduces the PCB hardware costs.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technology, in particular, a method and device for identifying equipment. Background technique [0002] At present, a large number of mobile terminals interact with external devices through Universal Serial Bus (USB) interfaces. Due to the integration and cost requirements of mobile terminals, mobile terminals need to be charged through USB peripherals, or, through USB interfaces Data transmission with mobile terminals. Therefore, the mobile terminal needs to quickly and accurately identify the external device through the USB interface to determine whether the USB external device is charging the mobile terminal or performing data transmission with the mobile terminal. [0003] In the prior art, USB peripherals of mobile terminals can be classified into three categories: standard chargers, non-standard chargers, and personal computer (Personal Computer, PC for short) devices....
