In order to illustrate the technical scheme of the application, the following description is made by specific examples.
Fig. 2 illustrates a functional block diagram of a multi-interface power communication system 10 provided in accordance with an embodiment of the present application. Referring to fig. 2, the multi-interface power communication system 10 includes a first interface, a second interface, a third interface, a first switching unit 101, a second switching unit 102, a selection switching unit 103, and a protocol unit 104. The first interface is electrically connected with the first switch unit 101 and the selection switch unit 103 respectively, the second interface is electrically connected with the second switch unit 102 and the selection switch unit 103 respectively, the third interface is electrically connected with the selection switch, the first switch unit 101 is electrically connected with the second switch unit 102, the protocol unit 104 is electrically connected with the first interface, the second interface, the third interface, the first switch unit 101, the second switch unit 102 and the selection switch unit 103 respectively, the first interface is used for being electrically connected with the first device 20, the second interface is used for being electrically connected with the second device 30, and the third interface is used for being electrically connected with the power supply unit 40.
Specifically, when the first interface is electrically connected to the first device 20, the protocol unit 104 is configured to control the first switch unit 101 to be turned on, and output a first control signal to the selection switch unit 103, where the selection switch unit 103 is configured to control connection between the third interface and the first interface according to the first control signal, so that the first device 20 and the power supply unit 40 implement communication through a d+/D-data line in the third interface, and the power supply unit 40 can determine that the first device 20 supports a high-power rapid charging protocol other than the protocol unit 104 by reading a current signal transmitted by the first device 20 on the d+/D-data line, thereby outputting high power, and charging the first device 20 through the third interface, the first switch unit 101 and the first interface, so as to improve the charging efficiency of the first device 20. When the second interface is electrically connected to the second device 30, the protocol unit 104 is configured to control the second switch unit 102 to be turned on, and output a second control signal to the selection switch unit 103, where the selection switch unit 103 is configured to control connection between the third interface and the second interface according to the second control signal, so that the second device 30 and the power supply unit 40 implement communication through a d+/D-data line in the third interface, and the power supply unit 40 can determine that the second device 30 supports a high-power fast charging protocol beyond the protocol unit 104 by reading a current signal transmitted by the second device 30 on the d+/D-data line, thereby outputting high power, and charging the second device 30 through the third interface, the second switch unit 102 and the second interface, and improving the charging efficiency of the second device 30. It can be seen that, in the multi-interface power supply communication system provided by the embodiment of the present application, the first device 20 or the second device 30 may communicate with the power supply unit 40 through the d+/D-data line in the third interface, and the power supply unit 40 may determine that the first device 20 or the second device 30 supports the high-power fast charging protocol other than the protocol unit 104 by reading the current signal transmitted by the first device 20 or the second device 30 on the d+/D-data line, so as to output high power to charge the first device 20 or the second device 30, thereby improving the charging efficiency of the first device 20 or the second device 30.
It should be noted that, the power supply unit 40 may be a power adapter, and the d+/D-data line in the third interface in the multi-interface power communication system 10 provided by the embodiment of the present application may enable the power adapter to communicate with the first device 20 or the second device 30, where the power adapter may detect a current signal transmitted by the first device 20 or the second device 30 on the d+/D-data line, and identify a fast charging protocol supported by the first device 20 or the second device 30. The power adapter will send a response signal supporting fast charge to either the first device 20 or the second device 30 in a predetermined current mode via the D +/D-data line. After receiving the response signal, first device 20 or second device 30 sends an instruction to allow fast charging to the power adapter via the D+/D-data line. After the power adapter obtains the permission command, the permission command is outputted to the first device 20 or the second device 30 with a larger current (e.g. 3A), so as to improve the charging efficiency of the first device 20 or the second device 30.
It should be noted that, when the first interface is electrically connected to the first device 20 or the second interface is electrically connected to the second device 30, the high power output by the power supply unit 40 may be the total output power of the power supply unit 40, so as to complete the power supply configuration.
It should be noted that the first interface, the second interface, and the third interface are all TYPE-C interfaces, where each interface includes a power line, a ground line, a CC (Configuration Channel, configuration channels), and a d+/D-data line. Wherein the CC configuration channel is used for device capability configuration and device type identification, and the D+/D-data line is used for a pair of differential data lines for digital data and signal transmission.
It should be noted that, the third interface may be connected to the power supply unit 40 by a power circuit, the CC configuration channel is connected to the power supply unit, the third interface may be connected to the first switch unit 101 and the second switch unit 102 by a power circuit, the third interface may be connected to the protocol unit 104 by a power circuit and the CC configuration channel is connected to the power supply unit, and the third interface may be connected to the selection switch unit 103 by a d+/D data line. The first interface and the first switch unit 101 may be connected to a power circuit, the first interface and the selection switch unit 103 may be connected to a d+/D-data line, the first interface and the protocol unit 104 may be connected to a CC configuration channel, and the first interface and the first device 20 may be connected to a power circuit, a CC configuration channel, and a d+/D-data line. The second interface and the second switch unit 102 may be connected by a power circuit, the second interface and the selection switch unit 103 may be connected by a d+/D-data line, the second interface and the protocol unit 104 may be connected by a CC configuration channel, and the second interface and the second device 30 may be connected by a power circuit, a CC configuration channel, and a d+/D-data line. The protocol unit 104 may be electrically connected with the first switch unit 101, the second switch unit 102 and the selection switch unit 103 in a controlled manner.
When the first interface is electrically connected to the first device 20 and the second interface is electrically connected to the second device 30, the protocol unit 104 is configured to control the first switch unit 101 and the second switch unit 102 to be turned on, and output a third control signal to the selection switch unit 103, and the selection switch unit 103 is configured to disconnect the third interface from the second interface according to the third control signal, even if the third interface is disconnected from the first interface. The protocol unit 104 outputs power of a preset voltage to the first device 20 and the second device 30, respectively, wherein the current output to the first device 20 or the second device 30 is one half of the current output by the power supply unit 40, thereby completing the power supply configuration.
The preset voltage may be set to 5V, for example.
The first device 20 may be, for example, a cell phone, a computer, or other electronic device. The second device 30 may be a cell phone, a computer or other electronic device.
It should be noted that, in the multi-interface power supply communication system 10, the state of the first device 20 connected by the first interface or the state of the second device 30 connected by the second interface is switched to the state of the first device 20 connected by the first interface and the state of the second device 30 connected by the second interface, the protocol unit 104 needs to disconnect the CC connection with the power supply unit 40 and reconnect the CC connection, so as to ensure that the power supply unit 40 converts from outputting high power to outputting standard charging power. Likewise, in the multi-interface power communication system 10, the state of the first device 20 is connected by the first interface and the state of the second device 30 is switched to the state of the first device 20 connected by the first interface or the state of the second device 30 connected by the second interface, which requires the protocol unit 104 to disconnect and reconnect the CC connection with the power supply unit 40, so as to ensure that the power supply unit 40 converts from the output standard charging power to the output high power.
It should be noted that, in the multi-interface power communication system 10 shown in fig. 1, when the first interface is connected to the first device 20 and the second interface is connected to the second device 30, if the power required by the first device 20 and the power required by the second device 30 are equal, the protocol unit 104 controls the first switch unit 101 to be turned on, and the power supply unit 40 supplies power to the first device 20 through the third interface, the first switch unit 101 and the first interface (main charging path). Meanwhile, the protocol unit 104 controls the second switching unit 102 to be turned on, and the power supply unit 40 supplies power to the second device 30 (main charging path) through the third interface, the second switching unit 102 and the second interface. If the power required by the first device 20 and the power required by the second device 30 are different, for example, the power required by the first device 20 is greater than the power required by the second device 30, at this time, the charging path for supplying power to the first device 20 by the power supply unit 40 is a main path, and the charging path for supplying power to the second device 30 by the power supply unit 40 is a branch path (the power supply unit 40 supplies power to the second device 30 through the third interface, the power supply module, the fourth switch unit and the second interface). However, in the case of branch power supply, the power module needs to convert the large voltage output from the power supply unit 40 into the small voltage to be output to the second device 30, which may cause power loss and generate heat. Compared to fig. 1, the multi-interface power communication system 10 (fig. 2) of the present application can reduce power consumption and heat generation by eliminating the power module, the third switch module and the fourth switch module.
In one embodiment of the present application, the first switch unit 101 includes a first switch, a first end of the first switch is electrically connected to the first interface, a second end of the first switch is electrically connected to the third interface, and a control end of the first switch is electrically connected to the protocol unit 104.
Specifically, the first switch is used to control the connection between the third interface and the first interface, so that the power supply unit 40 may charge the first device 20. When the first interface is electrically connected to the first device 20, the protocol unit 104 is configured to control the first switch to be turned on, and output a first control signal to the selection switch unit 103, where the selection switch unit 103 is configured to control connection between the third interface and the first interface according to the first control signal, so that the first device 20 and the power supply unit 40 implement communication through a d+/D-data line in the third interface, and the power supply unit 40 can determine that the first device 20 supports a high-power fast charging protocol other than the protocol unit 104 by reading a current signal transmitted by the first device 20 on the d+/D-data line, thereby outputting high power, and charging the first device 20 through the third interface, the first switch and the first interface, so as to improve the charging efficiency of the first device 20.
In one embodiment of the present application, the second switch unit 102 includes a second switch, a first end of the second switch is electrically connected to the second interface, a second end of the second switch is electrically connected to the third interface, and a control end of the second switch is electrically connected to the protocol unit 104.
In particular, the second switch is used to control the connection between the third interface and the second interface so that the power supply unit 40 can charge the second device 30. When the second interface is electrically connected to the second device 30, the protocol unit 104 is configured to control the second switch to be turned on, and output a second control signal to the selection switch unit 103, where the selection switch unit 103 is configured to control connection between the third interface and the second interface according to the second control signal, so that the second device 30 and the power supply unit 40 implement communication through a d+/D-data line in the third interface, and the power supply unit 40 can determine that the second device 30 supports a high-power fast charging protocol other than the protocol unit 104 by reading a current signal transmitted by the second device 30 on the d+/D-data line, thereby outputting high power, and charging the second device 30 through the third interface, the second switch and the second interface, and improving the charging efficiency of the second device 30.
In one embodiment of the present application, the selection switch unit 103 includes a selection switch, wherein a common terminal of the selection switch is connected to the third interface d+/D-data line, a first terminal of the selection switch is connected to the first interface d+/D-data line, a second terminal of the selection switch is connected to the second interface d+/D-data line, and a control terminal of the selection switch is in control electrical connection with the protocol unit 104.
Specifically, the selection switch is used to conduct the common terminal and the first terminal when the first interface is electrically connected to the first device 20, so that the third interface and the first interface are in communication connection, and the power supply unit 40 and the first device 20 are in communication, and perform power communication. The selection switch is further used for conducting the common terminal and the second terminal when the second interface is electrically connected with the second device 30, so that the third interface is in communication connection with the second interface, and the power supply unit 40 and the second device 30 are in communication for power communication.
It should be noted that, the power module, the third switch module and the fourth switch module in the existing multi-interface power communication system 10 can be omitted by adopting the selection switch, so that the power loss and the heat productivity can be reduced, meanwhile, the use of components is reduced, the cost is saved, and the volume of the product is reduced.
Illustratively, the selector switch may be a USB2.0 switch or other single pole double throw switch or other switching device, not limited herein.

Specifically, the controller chip is configured to control the first switch unit 101 to be turned on when the first interface is connected to the first device 20, and output a first control signal to the selection switch unit 103, where the selection switch unit 103 controls connection between the third interface and the first interface according to the first control signal.
