Fig. 2 is a flowchart of a method for identifying a device self-connection according to an embodiment of the present invention, as shown in fig. 2, the method including the steps of:
step S21, the target device detects that the interface is connected to the external device, and generates a first identification code.
Specifically, the first identification code may be a random number, and the interface may be a Type-C interface. In the above steps, the target device generates the first identification code after detecting that the interface is connected to the external device.
In an alternative embodiment, the target device includes an embedded processor that communicates with the USB PD controller via an I2C (Inter-Integrated Circuit, two-wire Serial) line, a Type-C interface, and a USB PD controller that controls the Type-C interface; the USB PD controller communicates with an externally connected Type-C interface through a CC bus. When the USB PD controller detects that the corresponding Type-C interface is connected with the external equipment, the embedded processor is informed, generates a first random number and transmits the first random number to the USB PD controller.
Step S23, requesting a second identification code from the external device, where the second identification code is an identification code generated when the external device detects connection with the interface.
In the above step, if the external device is the same as the target device, and the identification code is generated when the connection between the interface and the other device is detected, the identification code generated by the external device is the second identification code.
Step S25, comparing the first identification code with the second identification code when the second identification code is requested.
And step S27, determining whether the target device and the external device are the same device according to the comparison result.
In an optional embodiment, still taking the Type-C interface as an example, when the external device of the Type-C interface is the target device itself, that is, the external device of the Type-C interface and the Type-C target device are the same device, both the USB PD controllers of the target device detect that the corresponding interfaces are connected to the external device, and both request the random number received by the other USB PD controller from the embedded processor, and because the random numbers received by both the USB PD controllers are generated by the same embedded processing, the random number requested by both the USB PDs is the same as the random number received by itself, thereby determining that the target device, that is, the target device and the external device are the same device.
According to the method, the target device detects that the interface is connected with the external device, generates the first identification code, requests the external device for the second identification code, wherein the second identification code is the identification code generated when the external device detects that the interface is connected with the external device, compares the first identification code with the second identification code under the condition that the second identification code is obtained through the request, and determines whether the target device and the external device are the same device or not according to the comparison result. When the target equipment and the external equipment are the same equipment, the random numbers received by the USB PD controllers corresponding to the two interfaces are the same as the random numbers received by the external equipment detected by the target equipment and the interfaces are the same equipment; when the target equipment and the external equipment are not the same equipment and the external equipment also has the function of generating random numbers when detecting that the interface is connected with other equipment, the first identification code is different from the second identification code; when the target device and the external device are not the same device and the external device does not have the function of generating the random number when detecting that the interface is connected with other devices, the target device cannot request the identification code, so that whether the target device and the external device are the same device can be determined by requesting the random number obtained by the USB PD controller to be the received random number generated by the embedded processor. Further, as long as any one of two connected devices has the function of implementing the steps, the self-connection identification of the device can be achieved.

step S271, determining that the target device and the external device are the same device under the condition that the first identification code and the second identification code are the same.
And if the first identification code is the same as the second identification code, determining that the identification codes received by the USB PD controllers corresponding to the two interfaces are generated by one embedded processor, thereby determining that the target equipment and the external equipment are the same equipment.
Step S272, determining that the target device and the external device are not the same device when the first identification code is different from the second identification code.
And if the first identification code is the same as the second identification code, determining that the identification codes received by the USB PD controllers corresponding to the two interfaces are generated by different embedded processors, thereby determining that the target equipment and the external equipment are not the same equipment.
Optionally, according to the embodiment of the present application, after determining whether the target device and the external device are the same device according to the comparison result, the method further includes:
and step S29, if the comparison result indicates that the target device and the external device are the same device, terminating the communication between the target device and the external device.
In the above step, if the target device and the external device are the same device, the connection occurs between the two interfaces of the target device, and in order to prevent the device itself from charging the device, which affects the service life of the device, or damages the device, the communication of the two interfaces needs to be notified immediately. The step of stopping interface communication may be performed by the USB PD controller corresponding to any one of the interfaces.
Optionally, according to the embodiment of the present application, after determining whether the target device and the external device are the same device according to the comparison result, the method further includes:
step S211, if the comparison result indicates that the target device and the external device are not the same device, continuing to maintain the communication between the interface and the external device.
In the above step, if the target device and the external device are not the same device, the connection is not the self-connection of the device, and a situation that one interface of the device charges the other interface of the device will not occur, so that the two interfaces can be kept communicating continuously for charging or data transmission.
Optionally, according to the foregoing embodiment of the present application, in a case where obtaining the second identification code is not requested, the communication between the target device and the external device is terminated.
In an optional embodiment, taking the target device as a smart phone as an example, when the smart phone is connected to the charger through the Type-C interface, the USB PD controller of the interface receives a random number generated by an embedded processor of the smart phone, and because the charger does not have a function of generating the random number after detecting the external device, the USB PD controller of the smart phone cannot request the random number generated by the charger, and the smart phone determines that the device connected to the interface is not the same as the smart phone itself under the condition that the random number is not requested.
