[0002] In an existing multi-port power supply system, if multiple devices are connected to the multi-port power supply system, the multi-port power supply system will keep all power supply ports in non-fast charging mode.

[0069] As described in the background technology, in an existing multi-port power supply system, if multiple devices are connected to the multi-port power supply system, the multi-port power supply system will keep all power supply ports in non-fast charging mode. In this case, if the multi-port power supply system returns from multi-port operation to single-port operation, in order to restore the fast charging power supply of the power supply port during single-port operation, the multi-port power supply system will power off all power supply ports to meet the power supply needs of a single power supply port. However, for devices without a fast charging protocol and without an automatic reset function, after the power port loses power, the device requires the user to manually start it again before it can start working again. This phenomenon affects the user experience.

[0070] In order to solve the above problems, an embodiment of the present invention provides a multi-port power supply system, wherein each power supply port is respectively coupled to the output end of the protocol module and the output end of the protocol detection module through a protocol switch and a detection switch, the input end of the protocol module and the input end of the protocol detection module are coupled to the system control module, and the insertion detection module is respectively coupled to the power supply port and the system control module; the insertion detection module detects the connection or disconnection of the equipment at each power supply port in real time, and sends a first signal to the system control module; the protocol detection module detects the type of device connected to the power supply port of the turned-on detection switch, and sends a second signal to the system control module; the protocol module responds to the fast charging protocol request of the corresponding power supply port when any protocol switch is turned on; the system control module controls the connection or disconnection of the protocol switch or the detection switch based on the first signal and the second signal, and controls the voltage of the power supply port, so that when the multi-port power supply returns to the single-port power supply, the corresponding device is automatically provided with the required voltage.

[0071] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0072] Please refer to Figure 1 , an embodiment of the present invention provides a multi-port power supply system, comprising: a system control module 10, a protocol module 22, a protocol detection module 23, an insertion detection module 21 and N power supply ports 30, wherein N is an integer greater than or equal to 2;

[0073] Each power supply port 30 is coupled to the output end of the protocol module 22 through a protocol switch S0, and each power supply port 30 is also coupled to the output end of the protocol detection module 23 through a detection switch S1. The input end of the protocol module 22 and the input end of the protocol detection module 23 are coupled to the system control module 10; the insertion detection module 21 is coupled to the N power supply ports 30 and the system control module 10 respectively;

[0074] The insertion detection module 21 is used to detect the connection or removal of the device of each power supply port 30 in real time, and send a first signal to the system control module 10, wherein the first signal includes the position information of the power supply port 30 connected or removed from the device and the number information of the power supply ports 30 connected to the device;

[0075] The protocol detection module 23 is used to detect whether the device connected to the power supply port 30 corresponding to the turned-on detection switch S1 has a fast charging protocol, and send a second signal to the system control module 10, wherein the second signal includes the type of device connected to each corresponding power supply port 30, and the device type is a device with a fast charging protocol and a device without a fast charging protocol;

[0076] The protocol module 22 is used to respond to the fast charging protocol request of the corresponding power supply port 30 when any protocol switch S0 is turned on;

[0077] The system control module 10 is used to control the protocol switch S0 or the corresponding detection switch S1 corresponding to the power supply port 30 of the access device to be turned on or off based on the first signal and the second signal, so that the power supply port 30 corresponding to the turned-on protocol switch S0 and the turned-on detection switch S1 is continuously powered, wherein:

[0078] Only when the number of the power supply port 30 connected to the device is 1, the device can obtain the required voltage.

[0079] It can be seen that the system control module of the multi-port power supply system in the present invention can control the protocol switch or the detection switch to be turned on or off based on the first signal and the second signal, and control the voltage of the power supply port. Therefore, when the multi-port power supply system returns from multi-port power supply to single-port power supply, the multi-port power supply system can automatically provide the connected device with the required voltage.

[0080] Please continue to refer to Figure 1 In one embodiment, the above-mentioned controlling the corresponding protocol switch S0 or the corresponding detection switch S1 to be turned on or off based on the first signal and the second signal includes:

[0082] When the first signal indicates that the number of the power supply ports 30 of the access device 40 is multiple, based on the second signal, the protocol switch S0 or the corresponding detection switch S1 corresponding to each power supply port of the access device 40 is controlled to be turned on or off.

[0083] Now combined Figure 2 to Figure 8 The control method of the above system control module is described as follows:

[0084] In a specific implementation, when the first signal indicates that the number of the power supply port 30 of the access device 40 is 1, based on the second signal, controlling the protocol switch S0 or the detection switch S1 corresponding to the power supply port 30 of the access device 40 to be turned on includes:

[0085] When the number of the power supply ports 30 of the access device 40 represented by the first signal changes from 0 to 1, only the protocol switch S0 corresponding to the power supply port 30 of the access device 40 is controlled to be turned on;

[0086] When the number of the power supply ports 30 of the connected device represented by the first signal changes from multiple to one, the protocol switch S0 or the detection switch S1 corresponding to the power supply port 30 of the connected device is controlled to be turned on based on the second signal.

[0087] Specifically, please refer to Figure 2 , Figure 2 It shows a specific state diagram of the corresponding multi-port power supply system structure when the number of the power supply ports 30 of the access device 40 represented by the first signal changes from 0 to 1, and only the protocol switch S0 corresponding to the power supply port 30 of the access device 40 is controlled to be turned on.

[0088] In a specific implementation manner, when the first signal indicates that the number of the power supply ports 30 of the access device 40 changes from multiple to one, controlling the protocol switch S0 or the detection switch S1 corresponding to the power supply port 30 of the access device 40 to be turned on based on the second signal includes:

[0089] When the second signal indicates that the type of device 30 corresponding to the power supply port 30 of the connected device 40 is a device 30 with a fast charging protocol, the corresponding detection switch S1 is controlled to be disconnected to power off the corresponding power supply port 30, and the corresponding protocol switch S0 is controlled to be turned on;

[0090] Specifically, please refer to Figure 2, the first signal indicates that the number of the power supply ports 30 of the access device 40 changes from multiple to one, and when the second signal indicates that the type of device 30 corresponding to the power supply port 30 of the access device 40 is a device 30 with a fast charging protocol, the specific state diagram of the corresponding multi-port power supply system structure shows that, in this case, the multi-port power supply system controls the corresponding detection switch S1 to be disconnected to power off the corresponding power supply port 30, and controls the corresponding protocol switch S0 to be turned on,

[0091] When the second signal indicates that the type of device 40 corresponding to the power supply port 30 of the connected device 40 is a device 40 without a fast charging protocol, the corresponding detection switch S1 or protocol switch S0 is controlled to remain turned on, wherein:

[0092] When the second signal indicates that the detection switch S1 is not turned on, the protocol switch S0 corresponding to the power supply port 30 of the access device 40 is kept turned on.

[0093] Specifically, please refer to Figure 3 , when the first signal indicates that the number of the power supply ports 30 of the connected device 40 changes from multiple to one, and the second signal indicates that the type of device 40 corresponding to the power supply port 30 of the connected device 40 is a device 40 without a fast charging protocol, the specific state diagram of the corresponding multi-port power supply system structure shows that, in this case, the multi-port power supply system controls the corresponding detection switch S1 to be turned on;

[0094] Please refer to Figure 2 , when the first signal indicates that the number of the power supply ports 30 of the access device 40 changes from multiple to one, and the second signal indicates that the detection switch S1 is not turned on, the specific state diagram of the corresponding multi-port power supply system structure shows that, in this case, the multi-port power supply system keeps the protocol switch S0 corresponding to the power supply port 40 of the access device turned on.

[0095] In a specific implementation, when the first signal indicates that the number of the power supply ports 30 of the access device is multiple, based on the second signal, controlling the protocol switch S0 or the corresponding detection switch S1 corresponding to each power supply port 30 of the access device 40 to be turned on or off includes:

[0096] The first signal is characterized in that when the number of power supply ports 30 connected to the device increases, the detection switch S1 coupled to the corresponding power supply port 30 is controlled to be turned on;

[0097] The first signal is characterized in that when the number of the power supply ports 30 connected to the device is reduced, the detection switch S1 or the protocol switch S0 coupled to the corresponding power supply port 30 is controlled to be disconnected.

[0098] Specifically, please refer to Figure 4 , Figure 4 It shows that when the first signal indicates that the number of the power supply ports 30 of the access device 40 is multiple, and the first signal indicates that the number of the power supply ports 30 of the access device 40 increases, the detection switch S1 coupled to the corresponding power supply port 30 is turned on, and the specific state diagram of the corresponding multi-port power supply system structure;

[0099] Please refer to Figure 5 , Figure 5 , when the first signal indicates that the number of the power supply ports 30 of the connected device is multiple, and the first signal indicates that the number of the power supply ports 30 of the connected device 40 is reduced, a specific state diagram of the corresponding multi-port power supply system structure is shown. It can be seen that in this case, the multi-port power supply system controls the detection switch S1 coupled to the corresponding power supply port 30 to be disconnected;

[0100] Please refer to Figure 6 , Figure 6 It is shown that, when the first signal indicates that the number of the power supply ports 30 of the access device 40 is multiple and the first signal indicates that the number of the power supply ports 30 of the access device 40 is reduced, the specific state diagram of the corresponding multi-port power supply system structure shows that, in this case, the multi-port power supply system controls the protocol switch S0 coupled to the corresponding power supply port 30 to disconnect.

[0101] It can be seen that the system control module in the multi-port power supply system controls the protocol switch or the detection switch to be turned on or off based on the first signal and the second signal, so that the multi-port power supply system can supply power to the power supply port according to the first signal and the second signal sent by the insertion detection module and the protocol module to the system control module.

[0102] However, in order to enable the multi-port power supply system to automatically provide the required voltage to the corresponding device when a single port is powered, the system control module also needs to obtain the type of device connected to the power supply port corresponding to the channel turned on by the protocol switch, and the voltage required by the connected device. Therefore, the protocol module of the present invention also sends a third signal to the system control module.

[0103] In a preferred embodiment, the protocol module 22 is further configured to send a third signal to the system control module 10 when the corresponding protocol switch S0 is turned on, wherein the third signal includes a first sub-signal and a second sub-signal:

[0104] In this case, the protocol module 22 is further configured to:

[0105] When the corresponding protocol switch S0 is turned on, it detects whether the device of the corresponding power supply port 30 sends a fast charging protocol signal within the first set time;

[0106] If the fast charge protocol request is received within the first set time, a first sub-signal is sent to the system control module 10, where the first sub-signal includes a requested voltage of the device;

[0107] If the fast charging protocol request is not received within the first set time, a second sub-signal is sent to the system control module 10, and the second sub-signal is used to indicate that the corresponding device is a device without a fast charging protocol.

[0108] In practical applications, please refer to Figure 7 , the multi-port power supply system further includes a power supply module 24, a first end of the power supply module 24 is coupled to the system control module 10, and a second end of the power supply module 24 is respectively coupled to N power supply ports 30;

[0109] The system control module 10 is further configured to send a power supply control signal to the power supply module 24 based on the first signal, the second signal, and the third signal, so as to control the voltage of each power supply port 30 .

[0110] On this basis, the above-mentioned outputting a power supply control signal to the power supply module 24 based on the first signal, the second signal or the third signal to control the voltage of each power supply port 30 includes:

[0111] When the first signal indicates that the number of the power supply port 30 connected to the device is 1, based on the second signal and the third signal, the voltage of the corresponding power supply port 30 is controlled to be a specific voltage or a first voltage, and the specific voltage is the voltage requested by the device;

[0112] When the first signal indicates that the number of the power supply ports 30 connected to the device is plural, the voltage output by each power supply module 24 is controlled to be the first voltage.

[0113] Specifically, when the first signal indicates that the number of the power supply ports 30 connected to the device is 1, based on the second signal and the third signal, the power supply module 24 controls the voltage of the corresponding power supply port 30 to be a specific voltage or a first voltage, including:

[0114] If only the second signal is received, and the second signal indicates that the device type corresponding to the power supply port 30 of the connected device is a device without a fast charging protocol, the voltage of the corresponding power supply port 30 is controlled to be the first voltage;

[0115] If the first sub-signal is received, controlling the specific voltage output by the power supply module 24;

[0116] If the second sub-signal is received, the power supply module 24 controls the first voltage output by the power supply module 24 .

[0117] It can be seen that the system control module can control the power supply module to output a specific voltage or the first voltage based on the first signal, the second signal and the third signal, so that when the multi-port power supply system returns from multi-port power supply to single-port power supply, it can automatically provide the required voltage for the corresponding device.

[0118] In practical applications, please refer to Figure 8 The system control module 10 further includes a storage unit 12 and a control unit 11.
