Alternatively, the second charging interface 21 may be of the same type as the first charging interface 11, so as to ensure that a connection can be established between the first charging interface 11 and the second charging interface 21. Specifically, the electronic device 10 may determine the conduction parameter of the connection between the electronic device and the target device 20 in the following manner:

the first method is as follows: the electronic device 10 sends a signal to the target device 20 through each first data terminal, and when a signal fed back by the target device 20 is received through the corresponding first data terminal, the first data terminal is determined to be conductive to the second data terminal on the target device 20, so that the conduction parameter of the connection between the electronic device 10 and the target device 20 can be determined according to the number of conductive data terminals between the first charging interface 11 and the second charging interface 21.

In the electronic device in the above scheme, under the condition that the first charging interface 11 is connected with the second charging interface 21 of the target device 20, the control module 13 controls the signal processing module 12 to switch to the line transmission mode corresponding to the connection conduction parameter of the first charging interface 11 and the second charging interface 21, so that the signal transmission is performed between the electronic device 10 and the target device 20 according to the line transmission mode. In this way, under the condition that there may be partial poor data contact or damage between the first charging interface 11 of the electronic device 10 and the second charging interface 21 of the target device 20, the corresponding line transmission mode can be switched based on the conduction parameter of the connection between the first charging interface 11 and the second charging interface, so that the reliability of data transmission is ensured, and the abnormal resistance capability is improved.

As shown in fig. 4, an embodiment of the present application provides a communication method, which is applied to an electronic device, where the electronic device has a first charging interface, and the first charging interface includes a plurality of first data terminals; the method comprises the following steps:

step 41: and determining the conduction parameters under the condition that the first charging interface is connected with a second charging interface of the target equipment.

The electronic device determines the conduction parameters of the electronic device connected with the target device in the following manner:

the first method is as follows: the electronic equipment respectively sends signals to the target equipment through each first data terminal, and under the condition that the signals fed back by the target equipment are received through the corresponding first data terminals, the first data terminals are determined to be conducted with the second data terminals on the target equipment, so that the conduction parameters of the electronic equipment and the target equipment can be determined according to the conduction quantity of the data terminals between the first charging interface and the second charging interface.

Alternatively, taking the charging interface of the TYP-C type as an example, the charging interface of the TYP-C type has 4 data terminals (A, B, C, D), i.e. the first charging interface 11 may have at most 4 communication paths when connected to the second charging interface 21. Wherein, the corresponding relation between the conduction parameter and the line transmission mode of the first charging interface 11 and the second charging interface 21 includes:

Step 43: and the electronic equipment and the target equipment perform signal transmission according to the line transmission mode.

In the above scheme, under the condition that the first charging interface is connected with the second charging interface of the target device, the signal transmission between the electronic device and the target device is performed according to the line transmission mode by switching to the line transmission mode corresponding to the connection parameters of the first charging interface and the second charging interface. Therefore, under the condition that partial data contact is poor or the partial data contact is damaged possibly existing between the first charging interface of the electronic equipment and the second charging interface of the target equipment, the corresponding line transmission mode can be switched based on the conduction parameters of the connection between the first charging interface and the second charging interface, the reliability of data transmission is ensured, and the abnormal resistance is improved.

Optionally, the signal transmission between the electronic device and the target device according to the line transmission mode includes:

Therefore, the electronic device can receive the split signal blocks transmitted by the target device under the condition that the signal to be transmitted is split and then transmitted to the target device. The electronic equipment obtains a complete signal by time sequence synthesis under the condition of receiving a plurality of signal blocks transmitted by the target equipment, and obtains corresponding signal content by demodulation processing, so that the electronic equipment can execute corresponding functions according to the demodulated signal.

Optionally, determining a conduction parameter of the connection between the first charging interface and a second charging interface of the target device when the first charging interface is connected to the second charging interface includes:

and determining the conduction parameters under the condition that the electronic equipment is matched with the target equipment after the electronic equipment performs data transmission with the target equipment through a second protocol.

Alternatively, the first protocol may be BC1.2(Battery Charging v1.2) Charging protocol for determining the power type, i.e. whether the target device is a Charging device in case the electronic device is a powered device.

Alternatively, the second protocol may be a PD charging protocol, a QC fast charging protocol, a proprietary protocol, a normal non-fast charging protocol, etc. to further determine the charging type of the charging device if the target device is the charging device. In this way, when the type of the charging device is determined, the corresponding line transmission mode is switched to perform data transmission based on the conduction parameter between the electronic device and the target device.

As shown in fig. 5, the communication method of the present application is specifically described with reference to an electronic device as an example:

If the detection BC1.2 does not pass, the following step 502 is executed; if the detection BC1.2 passes, the following step 503 is executed to detect the quick charging type of the charging device, and if it is determined that the charging device is a charger of the following type: PD charger, QC fast charger, private agreement charger, ordinary non-fast charger.

For example: when only 1 line connection is detected, a single line transmission mode is selected; when detecting that 2 lines are connected, selecting a double-line transmission mode; when 3 lines are detected to be connected, a three-line transmission mode is selected; and when detecting that 4 lines are connected, selecting a four-wire transmission mode.

Step 506: and charging according to the compatible CC protocol.

Step 507: and carrying out data transmission according to the determined transmission mode. For example: in a multi-line transmission mode, a signal processing module is used for modulating and decomposing a complete signal into signal blocks for transmission, and target equipment receives the signal blocks and then demodulates and synthesizes the signal blocks to obtain the complete signal.

Step 508: and detecting whether the D +/D-can communicate. If communication is possible, the following step 509 is executed, and if communication is not possible, the following step 511 is executed.

Step 509: it is judged whether or not preset communication is possible. If the preset communication is possible, the above step 505 is executed, and if not, the following step 510 is executed.

Step 510: and charging is carried out according to a compatible D +/D-protocol.

Step 511: it is judged whether or not preset communication is possible. If the preset communication is possible, the above step 505 is executed, and if not, the following step 512 is executed.

Step 512: ending communication, charging according to common protocol
