Embodiment 1

[0025] According to an embodiment of the present invention, an embodiment of a method for identifying a self-connection of a device is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0026] figure 2 is a flow chart of a method for identifying a self-connection of a device according to an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:

[0027] In step S21, the target device detects that the interface is connected to an external device, and generates a first identification code.

[0028] Specifically, the above-mentioned first identification code may be a random number, and the above-mentioned interface may...

Embodiment 2

[0069] According to the above embodiments of the present application, a system for identifying self-connection of devices is also provided, Figure 5 is a schematic diagram of an optional system for identifying self-connection of devices according to an embodiment of the present application, combined with Figure 5 As shown, the system includes:

[0070] Interface 50.

[0071] Specifically, the above interface may be a Tepy-C interface.

[0072] The first controller 52 communicates with the interface and the second controller, and is configured to generate a first identification code when the second controller detects that the interface is connected to an external device.

[0073] Specifically, the first controller may be a USB PD controller communicating with the Tepy-C interface, and the first identification code may be a random number.

[0074] The second controller 54 communicates with the interface, and is used to receive the first identification code generated by the ...

Embodiment 3

[0081] According to the above embodiments of the present application, a system for identifying self-connection of devices is also provided, Figure 6 is a schematic diagram of an optional system for identifying self-connection of devices according to an embodiment of the present application, combined with Figure 6 As shown, the system includes:

[0082] The generation module 60 is used for generating a first identification code when the target device detects that the interface is connected to an external device.

[0083] Specifically, the above-mentioned first identification code may be a random number, and the above-mentioned interface may be a Type-C interface. In the above steps, after the target device detects that the interface is connected to the external device, it generates the first identification code.

[0084] The requesting module 62 is configured to request a second identification code from the external device, wherein the second identification code is an ident...

Abstract

The invention discloses a method, device and system for identifying self-connection of equipment. Wherein, the method includes: the target device detects that the interface is connected to the external device, and generates a first identification code; requests the external device for a second identification code, wherein the second identification code is an identification code generated when the external device detects that it is connected to the interface; When the second identification code is requested, the first identification code is compared with the second identification code; and whether the target device and the external device are the same device is determined according to the comparison result. The present invention solves the technical problem that in the prior art, when multiple Type-C interfaces of the same device are connected, the device cannot be identified, resulting in self-charging or even damage to the device.

Description

technical field [0001] The present invention relates to the field of equipment identification, in particular to a method, device and system for identifying equipment self-connection. Background technique [0002] With the promotion of the Type-C standard, more and more electronic devices currently support the Type-C interface, and devices that support two or more Type-C interfaces at the same time are becoming more and more common, such as Apple's MacBook and Google's Chromebooks, etc. Although Type-C has brought many conveniences to users (such as support for reversible insertion, fast charging, etc.), there are also some problems, even potential safety hazards. [0003] Such as figure 1 As shown, a notebook supports two Type-C interface (Type-C interface 1 and Type-C interface 2) output. In normal use, each interface can be connected to peripherals and supply power to peripherals, or connected to a charger to charge the notebook. But when the two interfaces are connect...
