[0049] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. The present disclosure is intended to cover any variations, uses or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in the present disclosure. The description and examples are to be considered exemplary only, and the true scope and spirit of the present disclosure are indicated by the following claims.

[0050] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.

[0051] The present invention provides a smart home device, such as Figure 1 As shown, the smart home device 100 includes:

[0052] Power module 101;

[0053] Interface 102, used to connect to the powered device 200;

[0054] A first control module 103, connected to the interface 102, for acquiring device information of a powered device 200 plugged into the interface 102, and determining a power supply mode of the powered device 200 according to the device information;

[0055] The second control module 104 is connected to the first control module 103 and the power module 101 respectively, and is used to control the power module 101 to supply power to the powered device 200 according to the power supply mode.

[0056] In some embodiments, the smart home device may be a smart TV with a display screen.

[0057] In some other embodiments, the smart home device may further include: a smart speaker with a display screen and / or a smart cleaning device. The smart cleaning device includes but is not limited to: a sweeping robot, etc.

[0058] The power module is used to supply power to the powered device. Exemplarily, the power module may be a module including a power source and other components for supplying power.

[0059] The powered device may be an electronic device and / or an electrical device that operates based on electricity. Exemplarily, the powered device includes but is not limited to a mobile phone, a computer, a tablet, and a smart home.

[0060] The interface is used to connect the smart home device to the powered device, and after the connection, the smart home device can supply power to the powered device through the interface. Exemplarily, the interface includes but is not limited to a Universal Serial Bus (USB) interface, a high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE) interface, and a Serial Advanced Technology Attachment (SATA) interface.

[0061] The first control module is used to obtain device information of the powered device and determine the power supply mode of the powered device according to the device information. For example, the first control module can be a chip with functions of receiving, analyzing and processing information, such as a main chip (System on Chip, SOC), etc. If the smart home device is a smart TV, the first control module can include: a TV main chip (Television System on Chip, TV-SOC).

[0062] The second control module is used to control the power module to supply power to the powered device through the interface. Exemplarily, the second control module can be any chip with a power control function, such as a USB power management chip (USB Power Management Integrated Circuits, USB-PM).

[0063] The device information may be configuration information of the powered device, such as the function, type, data transmission mode, and power supply mode of the powered device. Exemplarily, the device information may be a device descriptor.

[0064] In the embodiment of the present disclosure, the power supply mode can be determined by the power supply parameters included in the device information. Exemplarily, the device information may include the maximum power consumption (bMaxPower) of the powered device during operation, so as to determine the size of the power supply current required by the powered device. For example, when bMaxPower = 500mA, the power supply mode can be set to: the current output by the power module is 1A. For different types of powered devices, the device information obtained is different, and the determined power supply mode is different. In this way, the power supply mode can be determined according to the device information of the powered device to meet the power supply requirements of different powered devices.

[0065] In another embodiment, the data transmission mode may also be determined according to the data transmission parameters included in the device information. Exemplarily, the device information may include the device transmission protocol (bDeviceProtocol) of the powered device. In this way, the transmission protocol used for transmitting data through the interface between the smart home device and the powered device may be determined according to the transmission protocols supported by the smart home device and the powered device respectively. For example, when both the smart home device and the powered device support the USB3.0 protocol, the protocol of USB3.0 or below (such as USB2.0, etc.) may be determined as the data transmission protocol, thereby adjusting the data transmission speed of the powered device.

[0066] Different charging protocols correspond to different charging efficiencies and support different charging parameters, so the applicable charging mode and / or charging parameters can be determined according to the charging protocol.

[0067] The power supply mode may be an operating parameter of the power module when supplying power, for example, the magnitude of the current and / or voltage output by the power module, etc. For example, the power supply mode of the voltage module in the embodiment of the present disclosure includes but is not limited to an output current of 1A, an output current of 2A, and an output current of 3A, etc.

[0068] In the embodiments of the present disclosure, the smart home device may be provided with multiple interfaces, each of which may be connected to a powered device. Thus, through the multiple interfaces provided on the smart home device, one smart home device may be connected to multiple powered devices and supply power to multiple powered devices. Thus, the power supply efficiency of the smart home device may be further improved, and the user experience may be improved.

[0069] In the disclosed embodiment, on the one hand, by connecting the first control module and the second control module, the integration of functions between different modules is realized, the complex software improvement process is reduced, and a series of operations such as obtaining device information, determining the power supply mode, and controlling the power supply of the power module are realized through the connection improvement between the modules, which is convenient to operate. On the other hand, by determining the power supply mode through the device information of the powered device obtained, the subsequent control of the power supply of the power module can meet the power supply requirements of different powered devices, reduce the situation where the powered device is insufficiently powered due to the low output of the power module, or the powered device is damaged or even lost due to the high output of the power module, improve the versatility of smart home devices, and improve user experience.

[0070] In some embodiments, the first control module is connected to the second control module via a bus.

[0071] In the embodiment of the present disclosure, the first control module and the second control module may be connected via a bus, and the bus may include a data bus, a control bus, and an address bus, etc., which are divided into two types: a serial bus and a parallel bus.

[0072] For example, after determining the power supply mode according to the acquired device information, the first control module can transmit the relevant information including the power supply mode to the second control module through the bus, and the second control module then performs power supply control according to the relevant information of the power supply mode received from the bus. In this way, the integration of the functions of the first control module and the second control module is achieved, the complex software improvement process is reduced, and the connection method through the bus is simple, convenient and easy to operate.

[0073] In some embodiments, the bus is an IIC integrated circuit bus.

[0074] In the disclosed embodiment, an integrated circuit bus (Inter-Integrated Circuit, IIC) can be used to connect the first control module and the second control module. IIC includes two signal lines, one is a data signal line (SerialData, SDA), which is responsible for data transmission between devices connected through IIC, and the other is a clock signal line (System ClockLine, SCL), which is responsible for generating synchronous clock pulses and synchronous data transmission.

[0075] For example, the SDA pins of the first control module and the second control module can be connected to the SDA pin of the IIC, the SCL pins of the first control module and the second control module can be connected to the SCL pin of the IIC, and the power supply and ground pins of the IIC bus can be set, so that the first control module and the second control module can be connected through the IIC. In this way, the connection method of connecting the first control module and the second control module through the IIC can realize the data transmission between the first control module and the second control module through the data transmission function of the SDA and the synchronous data transmission function of the SCL, and the method of connecting through the IIC is simple, convenient and easy to operate.

[0076] In some embodiments, the first control module is specifically configured to trigger an interrupt process when detecting that the powered device is plugged into the interface, and read device information of the powered device based on the interrupt process.

[0077] In the embodiment of the present disclosure, the insertion of the powered device can be detected by the first control module. For example, the first control module can detect the change of the signal at the interface to determine whether the powered device is plugged in. For example, when the powered device is not plugged in, the level signal at the interface is low, and when the powered device is plugged in, the level signal at the interface becomes high.

[0078] In the disclosed embodiment, when it is detected that a powered device is plugged into the interface, the first control module performs interrupt processing, suspends the remaining tasks currently being executed, and preferentially reads the device information of the powered device, so as to facilitate the subsequent determination of the power supply mode and the power supply to the powered device based on the power supply mode. In this way, by introducing the interrupt processing of the first control module and timely reading the device information of the plugged powered device, the power supply efficiency of the smart home device can be improved, the preparation time for power supply can be reduced, and the user experience can be improved.

[0079] In some embodiments, the first control module is specifically used to trigger interrupt processing when it detects that the powered device is unplugged from the interface, and send control information to the second control module based on the interrupt processing; wherein the control information is used for the second control module to control the power supply module to stop supplying power.

[0080] In the embodiment of the present disclosure, when it is detected that the powered device is unplugged from the interface, the power supply module can be controlled to stop supplying power through interrupt processing. In this way, on the one hand, the power supply can be stopped when no powered device is plugged in, thereby reducing the waste of power supply resources. On the other hand, the interrupt processing method can promptly stop powering the interface where the powered device is unplugged, thereby improving the safety of power supply.

[0081] In some embodiments, the interface is a USB universal serial bus interface.

[0082] In an embodiment of the present disclosure, a USB interface can be used to power a powered device. Exemplarily, the USB interface may include a micro USB (Micro USB), a mini USB (Mini USB), a type A USB (USB Type-A), a type B USB (USB Type-B) and / or a type C USB (USB Type-C), etc.

[0083] The USB interface supports hot plugging, and the USB interface standard is unified and widely used in a variety of smart devices. Therefore, most smart devices support plugging into the USB interface, so that a variety of smart devices can be powered through the USB interface of the smart home device. In this way, a variety of smart devices that support the USB interface can be powered through the USB interface of the smart home device, which can further improve the versatility of the smart home device and enhance the user experience.

[0084] The present disclosure also provides a device power supply method, which is performed by the smart home device described in any of the above embodiments, such as Figure 2 As shown, the method may include:

[0085] Step 110: Detect whether a powered device is plugged into the interface;

[0086] Step 120: when it is detected that a powered device is plugged into the interface, read device information of the powered device;

[0087] Step 130: Determine a power supply mode for supplying power to the powered device according to the device information;

[0088] Step 140: According to the power supply mode, control the power supply module of the smart home device to supply power to the powered device.

[0089] The powered device may be an electronic device and / or an electrical device that operates based on electricity. Exemplarily, the powered device includes but is not limited to a mobile phone, a computer, a tablet, and a smart home.

[0090] The interface is used to connect the smart home device to the powered device, and after the connection, the smart home device can supply power to the powered device through the interface. Exemplarily, the interface includes but is not limited to a Universal Serial Bus (USB) interface, a high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE) interface, and a Serial Advanced Technology Attachment (SATA) interface.

[0091] In the embodiment of the present disclosure, the device information of the powered device can be obtained by a chip having the functions of receiving, analyzing and processing information, such as a main chip (System on Chip, SOC), and the power supply mode of the powered device can be determined according to the device information. If the smart home device is a smart TV, the chip may include: a TV main chip (Television System on Chip, TV-SOC).

[0092] In the embodiments of the present disclosure, any chip with a power control function, such as a USB power management chip (USB Power Management Integrated Circuits, USB-PM), etc., can be used to control the power module to supply power to the powered device through an interface.

[0093] The device information may be configuration information of the powered device, such as the function, type, data transmission mode, and power supply mode of the powered device. Exemplarily, the device information may be a device descriptor.

[0094] In the embodiment of the present disclosure, the power supply mode can be determined by the power supply parameters included in the device information. Exemplarily, the device information may include the maximum power consumption (bMaxPower) of the powered device during operation, so as to determine the size of the power supply current required by the powered device. For example, when bMaxPower = 500mA, the power supply mode can be set to: the current output by the power module is 1A. For different types of powered devices, the device information obtained is different, and the determined power supply mode is different. In this way, the power supply mode can be determined according to the device information of the powered device to meet the power supply requirements of different powered devices.

[0095] In another embodiment, the data transmission mode may also be determined according to the data transmission parameters included in the device information. Exemplarily, the device information may include the device transmission protocol (bDeviceProtocol) of the powered device. In this way, the transmission protocol used for transmitting data through the interface between the smart home device and the powered device may be determined according to the transmission protocols supported by the smart home device and the powered device respectively. For example, when both the smart home device and the powered device support the USB3.0 protocol, the protocol of USB3.0 or below (such as USB2.0, etc.) may be determined as the data transmission protocol, thereby adjusting the data transmission speed of the powered device.

[0096] Different charging protocols correspond to different charging efficiencies and support different charging parameters, so the applicable charging mode and / or charging parameters can be determined according to the charging protocol.

[0097] The power supply mode may be an operating parameter of the power module when supplying power, for example, the magnitude of the current and / or voltage output by the power module, etc. For example, the power supply mode of the voltage module in the embodiment of the present disclosure includes but is not limited to an output current of 1A, an output current of 2A, and an output current of 3A, etc.

[0098] In the embodiments of the present disclosure, multiple interfaces can be set on the smart home device, and each interface can be connected to a powered device. In this way, through the multiple interfaces set on the smart home device, one smart home device can be connected to multiple powered devices and supply power to multiple powered devices. In this way, the power supply efficiency of the smart home device can be further improved, and the user experience can be improved.

[0099] In the disclosed embodiment, the power supply mode is determined by obtaining the device information of the powered device, so that the subsequent control of the power supply of the power module can meet the power supply requirements of different powered devices, reduce the situation where the powered device is insufficiently powered due to too low output of the power module, or is damaged or even lost due to too high output of the power module, thereby improving the versatility of smart home devices and improving user experience.

[0100] In some embodiments, Figure 3 As shown, step 120 may include:

[0101] Step 121: When it is detected that a powered device is plugged into the interface, an interrupt process is triggered;

[0102] Step 122: Based on the interrupt processing, read the device information of the powered device.

[0103] In the embodiment of the present disclosure, the insertion of the powered device can be detected. Exemplarily, the change of the signal at the interface can be detected to determine whether the powered device is inserted. For example, when the powered device is not inserted, the level signal at the interface is low, and when the powered device is inserted, the level signal at the interface becomes high.

[0104] In the embodiment of the present disclosure, when it is detected that a powered device is plugged into the interface, the interrupt processing is executed to suspend the other currently executed tasks, and the device information of the powered device is read first, so as to facilitate the subsequent determination of the power supply mode and the power supply to the powered device based on the power supply mode. In this way, by introducing the interrupt processing and timely reading the device information of the plugged powered device, the power supply efficiency of the smart home device can be improved, the preparation time for power supply can be reduced, and the user experience can be improved.

[0105] In some embodiments, step 120 may include:

[0106] Sending a query request to the powered device via the interface;

[0107] The device information returned by the powered device based on the query request is received.

[0108] In the embodiment of the present disclosure, when it is detected that a powered device is plugged into the interface, a query request can be sent to the powered device through the interface to obtain device information. In this way, the device information can be obtained in a timely manner to facilitate the subsequent determination of the power supply mode.

[0109] In some embodiments, step 130 may include:

[0110] When the device information indicates that the operating current of the powered device is greater than the first current and less than the second current, determining that the power supply mode for supplying power to the powered device is the first power supply mode;

[0111] When the device information indicates that the operating current of the powered device is greater than or equal to the second current and less than or equal to the third current, determining that the power supply mode for supplying power to the powered device is the second power supply mode; wherein the output current of the power module in the second power supply mode is greater than the output current of the power module in the first power supply mode;

[0112] When the device information indicates that the operating current of the powered device is greater than the third current, the power supply mode for supplying power to the powered device is determined to be the third power supply mode; wherein the output current of the power module in the third power supply mode is greater than the output current of the power module in the second power supply mode.

[0113] The first current, the second current and the third current can meet the power supply current output of different types of powered devices and can be set according to actual needs. For example, the first current can be 1A, the second current can be 2A, and the third current can be 3A.

[0114] In the embodiment of the present disclosure, the corresponding power supply mode is determined according to the device information of the powered device, so that the power module outputs the corresponding power supply current, thereby meeting the power supply demand of the powered device.

[0115] In some embodiments, step 140 may include:

[0116] According to the power supply mode, the switching frequency and / or duty cycle of the power supply in the power supply module is adjusted.

[0117] In the embodiment of the present disclosure, the switching frequency and / or duty cycle of the power supply in the power module can be used to provide a power supply output that meets the power supply mode. For example, when the power supply current in the power supply mode is high, the switching frequency and / or duty cycle of the power supply in the power module can be increased to meet the power supply current output required by the power supply mode.

[0118] In some embodiments, the method further comprises:

[0119] When it is detected that the powered device plugged into the interface is unplugged, the power module is controlled to stop supplying power.

[0120] In the embodiment of the present disclosure, when it is detected that the powered device is unplugged from the interface, the power supply module is controlled to stop supplying power. The power supply can be stopped when no powered device is plugged in, so as to reduce the waste of power supply resources.

[0121] In some embodiments, when it is detected that a powered device plugged into the interface is unplugged, the power supply module can be controlled to stop supplying power through interrupt processing.

[0122] In the embodiment of the present disclosure, when it is detected that the powered device is unplugged from the interface, the power module can be controlled to stop supplying power through interrupt processing. In this way, the power supply to the interface of the powered device unplugged can be stopped in time through interrupt processing, thereby improving the safety of power supply.

[0123] At present, there is a phenomenon that the TV or the USB peripheral (USB-device) of the household appliance TV may be reset due to occasional overcurrent and / or overvoltage in the USB, which will seriously affect the safety of the peripheral device and the TV itself, and will also affect the user experience.

[0124] When the TV is in normal power-on state and the connected current specification is small, the USB chip (USB-Integrated Circuit Chip, USB-IC) will not overcurrent. This is mainly for some large mobile hard drives or mobile devices with high power requirements. The USB-IC will overcurrent when the TV is powered on, which will cause the USB peripherals to reset repeatedly, and even cause the TV to reset repeatedly.

[0125] Based on this, the present disclosure also provides a smart identification power supply method based on TV-USB. When the TV is connected to any USB peripheral device, it can intelligently identify the current demand required for connecting to the USB peripheral device, and supply power according to the pre-designed power supply mode, thereby solving the problem of peripherals and TV-reset caused by USB-IC overcurrent / overvoltage, and at the same time greatly improving the user experience. This method allows the TV USB port to intelligently identify the type of device connected and automatically adjust the power output and data transmission speed. When the USB exceeds the current limit of 1.5A, other channels can be selected for the TV-USB port to support existing mobile devices to maximize device protection and improve user experience.

[0126] Exemplarily, the TV here is one of the aforementioned smart home devices, and the USB peripheral here is one of the aforementioned powered devices.

[0127] like Figure 4 , which is a schematic diagram of a framework of an intelligent identification and power supply method based on TV-USB provided in an embodiment of the present disclosure.

[0128] The specific process of a TV-USB-based intelligent identification power supply method provided by the present disclosure is as follows:

[0129] Process 1:

[0130] 1. Initialize the USB host controller: Initialize the USB host controller on the main chip (such as the MTK-5867 chip) so that it can detect the insertion and removal events of USB devices (such as USB flash drives, mobile hard drives, and other storage peripherals).

[0131] 2. Detect USB insertion events: When a USB device is inserted into the USB interface of the main chip, the main chip will detect the insertion event and trigger the corresponding interrupt.

[0132] 3. Interrupt handler: The main chip will call the interrupt handler to handle the USB insertion event. In the interrupt handler, the main chip will send a device descriptor request to the USB device to obtain basic information about the device.

[0133] 4. Device descriptor: The USB device returns a device descriptor, which contains the device's power requirements (the bMaxPower field indicates the required power information). The main chip parses the bMaxPower field included in the device descriptor to obtain the device's power requirements.

[0134] 5. Power supply requirement information: The main chip will tell USB-PM to perform the software operation of the second process through IIC communication according to the power supply requirement information of the device.

[0135] 6. USB unplug event: When the USB device is unplugged from the USB interface of the main chip, the main chip will detect the unplug event and trigger the corresponding interrupt. In the interrupt handler, the main chip will notify the USB-PM to turn off the power output of the USB interface to protect the device and the main chip.

[0136] Exemplarily, the main chip here is a type of the aforementioned first control module, the USB device here is a type of the aforementioned powered device, the USB interface here is a type of the aforementioned interface, the interrupt handler here is a type of the aforementioned interrupt handler, the device descriptor request here is a type of the aforementioned query request, the power supply requirement information here is a type of the aforementioned power supply parameter, the device descriptor here is a type of the aforementioned device information, the IIC here is a type of the aforementioned bus, and the USB-PM here is a type of the aforementioned second control module.

[0137] The specific process of process 1 is as follows Figure 5 As shown, including:

[0138] Step 210: TV-SOC initializes USB;

[0139] Step 220: TV-SOC detection plugging and unplugging;

[0140] Step 230: triggering an interrupt to obtain power supply information;

[0141] Step 240: Inform the USB-PM to select a power supply output.

[0142] In the disclosed embodiment, in order to make the TV-SOC and the USB-PM communicate via IIC, they need to be connected on the same IIC bus.

[0143] like Figure 6 , which is a schematic diagram of the connection relationship between a TV-SOC and a USB-PM provided by an embodiment of the present disclosure.

[0144] Process 2:

[0145] 1. Connect the SDA and SCL pins of the TV-SOC and USB power management chip to the SDA and SCL pins of the same IIC bus respectively.

[0146] 2. Determine the power and ground pins of the IIC bus and connect them to the corresponding pins of the SOC and USB power management chip.

[0147] In step 5 of process 1: After USB-PM receives the communication content of SOC-IIC, it will select the corresponding power supply mode according to the required power demand and output the corresponding current 1A / 2A / 3A to the USB peripheral.

[0148] like Figure 7 FIG. 1 is a flow chart of a method for intelligently identifying and powering a TV-USB device according to an embodiment of the present disclosure. Figure 2 .

[0149] Process 3:

[0150] After receiving the current demand signal transmitted by the SOC main chip IIC, it makes a judgment based on the transmitted current demand signal:

[0151] When bMaxPower>500mA, USB-PM configures the register to output the switching frequency and duty cycle corresponding to 1A, thereby achieving the required output current of 1A;

[0152] When bMaxPower>1000mA, USB-PM configures the register to output the switching frequency and duty cycle corresponding to 2A, thereby achieving the required output current of 2A;

[0153] When bMaxPower>1500mA, USB-PM configures the register to output the switching frequency and duty cycle corresponding to 3A, thereby achieving the required output current of 3A.

[0154] The intelligent identification power supply method based on TV-USB provided in the embodiment of the present disclosure enables the USB interface to automatically adjust the output current and voltage according to the needs of the device to meet the power supply needs of the device. In this way, different power outputs can be provided for different types of devices through USB intelligent power supply, thereby protecting the devices from damage caused by overcurrent and overvoltage. At the same time, it also greatly improves the user experience of TV users;
