Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] The implementation details of the technical solutions of the embodiments of the present application will be described in detail below.

[0031] In one embodiment, as Figure 1 shown, a structural schematic diagram of a USB wireless docking station is provided. The USB wireless docking station 100 includes a USB hub 101, a Bluetooth module 102, a microprocessor 103, and a power supply circuit 104. Each component of the USB wireless docking station 100 will be described in detail below.

[0032] The USB hub 101 is an integrated circuit chip used for data transmission and power management between USB devices. The USB hub 101 usually has multiple USB interfaces. Through these USB interfaces, multiple external USB devices 200 can be connected to achieve data transmission and device management. Among them, the external USB device 200 can be a USB-powered table lamp, atmosphere lamp, small fan, mouse pad with lighting effects, headphone stand, mouse cable organizer, laptop cooling stand, etc. These external USB devices 200 are devices with low speed, low power consumption, and no high-speed communication requirements.

[0033] In practical applications, Figure 1 the number of USB interfaces shown in is for reference only. The actual number of USB interfaces depends on the expansion ability of the USB hub 101, so that the number of USB interfaces supported by the USB wireless docking station 100 can be increased. Among them, the USB hub 101 in the USB wireless docking station 100 of this embodiment can expand the USB interfaces of the master device, so that the master device can support multiple different external USB devices 200 to be connected through multiple USB interfaces.

[0034] The Bluetooth module 102 integrates Bluetooth communication functions. Through the Bluetooth module 102, the USB wireless docking station 100 can establish a Bluetooth connection with an external Bluetooth device for wireless communication and data transmission, so that there is no need to connect the docking station to the host device via a cable, and the USB wireless docking station 100 does not occupy any exposed physical USB interfaces of the external Bluetooth device, thus avoiding the occupation of the high-speed interfaces of the external Bluetooth device. Here, the external Bluetooth device is essentially the host device, that is, the device used to receive, control, and process the data of the external USB device 200.

[0035] It can be understood that when using a wired docking station for expansion, it is necessary to connect the USB docking station to the host device via a cable, which limits the connection and layout positions of the USB docking station to the cable length. At the same time, in scenarios where the host device needs to be frequently moved away, the USB docking station needs to be frequently plugged and unplugged, resulting in cumbersome operations. Based on this, the USB wireless docking station 100 in this embodiment only needs to be deployed at any position within the effective Bluetooth coverage range of the external Bluetooth device, without the need for frequent plugging and unplugging, and is not restricted by the cable length during use.

[0036] In one embodiment, the Bluetooth radio frequency unit 1021 and the Bluetooth baseband unit 1022 are combined to form a complete Bluetooth module 102 to achieve wireless communication and data transmission between devices. The Bluetooth radio frequency unit 1021 is configured to perform Bluetooth communication with an external Bluetooth device, including signal transmission and signal reception. Specifically, it converts the analog signal (modulated signal) from the Bluetooth baseband unit 1022 into a radio frequency signal and sends it out. And captures the radio frequency signal sent by the external Bluetooth device and converts it into a form that can be processed by the Bluetooth baseband unit 1022.

[0037] The Bluetooth baseband unit 1022 is respectively connected to the Bluetooth radio frequency unit 1021 and the microprocessor 103, and is configured to process the data transmitted by the Bluetooth radio frequency unit 1021 and the microprocessor 103, including data modulation and demodulation. Specifically, for the data transmitted by the microprocessor 103, the Bluetooth baseband unit 1022 modulates the digital signal into an analog signal for further processing by the Bluetooth radio frequency unit 1021. For the data transmitted by the Bluetooth radio frequency unit 1021, the Bluetooth baseband unit 1022 demodulates it into a digital signal.

[0038] The microprocessor 103 is respectively connected to the Bluetooth module 102 and the USB hub 101. The microprocessor 103 has the ability to forward data and can forward the data transmitted by the Bluetooth module 102 and the USB hub 101 to achieve communication between the external USB device 200 and the external Bluetooth device. Refer to Figure 1The data transfer direction shown. Specifically, the external USB device 200 is connected to the USB hub 101 through the USB interface and transfers data to the microprocessor 103. After receiving the data transferred by the USB hub 101, the microprocessor 103 can process and forward the data. Finally, through the Bluetooth connection established with the external Bluetooth device by the Bluetooth module 102, the data of the USB wireless docking station 100 is sent to the external Bluetooth device. Similarly, the Bluetooth connection established between the external Bluetooth device and the Bluetooth module 102 transfers data to the microprocessor 103. After receiving the data transferred by the Bluetooth module 102, the microprocessor 103 can also process and forward the data and transfer the data to the USB hub 101. Thus, the microprocessor 103 can forward the data from the USB hub 101 and the Bluetooth module 102 as needed to realize the communication between the external USB device 200 and the external Bluetooth device.

[0039] In practical applications, the microprocessor 103 in the wireless docking station 100 has the ability to expand the external storage unit. The external storage unit stores periodic control instructions. Among them, the periodic control instructions are sent to the USB wireless docking station 100 by the external Bluetooth device multiple times. These periodic control instructions are characterized by repeated execution, large segments, and complexity. Based on this, when it is necessary to execute these stored control instructions again, the microprocessor 103 can directly read the relevant control instructions from the external storage unit and execute them, without the need for the external Bluetooth device to send the repeatedly executed control instructions to the wireless docking station 100 again, thus saving communication bandwidth.

[0040] In one embodiment, the USB wireless docking station 100 further includes a power supply circuit 104. The power supply circuit 104 is respectively connected to the Bluetooth module 102, the microprocessor 103, and the USB hub 101, as Figure 1 shown, Figure 1 which shows the power supply direction of the power supply circuit 104. Thus, the power supply circuit 104 can supply power to the Bluetooth module 102, the microprocessor 103, and the USB hub 101 to ensure that the Bluetooth module 102 can establish a Bluetooth connection with the external Bluetooth device, ensure that the microprocessor 103 can realize data forwarding, and at the same time ensure the normal operation of the external USB device 200 connected to the USB hub 101. The power supply circuit 104 in this embodiment can provide stronger power supply ability to supply power to the external USB device 200.

[0041] In the above embodiments, the Bluetooth module 102 in the USB wireless docking station 100 provides Bluetooth transceiver capabilities, the microprocessor 103 in the USB wireless docking station 100 provides data forwarding capabilities, and the USB hub 101 in the USB wireless docking station 100 provides multiple USB interfaces. Thus, the USB wireless docking station 100 is a USB multi-interface docking station with Bluetooth transceiver capabilities and data forwarding capabilities, which can avoid multiple low-speed external USB devices 200 from occupying high-speed interfaces and can also solve the limitations and cumbersome operations brought by cables. At the same time, the USB wireless docking station 100 also includes a power supply circuit 104, which can not only ensure the working power required by the USB wireless docking station 100, but also provide working power for multiple connected external USB devices 200, improving the power supply capacity of the USB wireless docking station 100.

[0042] In one embodiment, a circuit board is provided. When divided according to functional uses, the circuit board can be divided into a Bluetooth module 102, a USB hub 101, a microprocessor 103, and a power supply circuit 104. With the continuous development of integrated circuit technology, the Bluetooth module 102, the microprocessor 103, the USB hub 101, and the power supply circuit 104 in the USB wireless docking station 100 can be integrated into one circuit board, which can simplify the design of the docking station, reduce the physical size of the docking station, save desktop space, and at the same time improve the overall performance, stability, and reliability and reduce power consumption.

[0043] In one embodiment, as Figure 2 shown, Figure 2 a schematic framework diagram of a communication system is shown. The communication system includes an external USB device 200, an external Bluetooth device, and a USB wireless docking station 100. These devices can communicate and connect with each other to achieve data transmission and function expansion.

[0044] The external USB device 200 is a common external device, and the external USB device 200 is connected to the USB interface provided by the USB wireless docking station 100.

[0045] The external Bluetooth device has Bluetooth transceiver functions and can achieve short-distance communication and data transmission between devices, so that it can establish a Bluetooth connection with the USB wireless docking station 100.

[0046] The USB wireless docking station 100 is equivalent to a communication bridge between an external USB device 200 and an external Bluetooth device. The Bluetooth module 102 of the USB wireless docking station 100 can establish a Bluetooth connection with the external Bluetooth device, thereby enabling data transmission between the USB wireless docking station 100 and the external Bluetooth device; the USB hub 101 of the USB wireless docking station 100 can provide multiple USB interfaces for multiple external USB devices 200 to access, and data transmission between the USB wireless docking station 100 and the external USB device 200 can be achieved through the USB interface. On this basis, the data of the external USB device 200 can be read by the USB wireless docking station 100 through the USB interface, and then transmitted to the external Bluetooth device through the Bluetooth connection between the Bluetooth module 102 of the USB wireless docking station 100 and the external Bluetooth device. Similarly, the data of the external Bluetooth device can be transmitted to the USB wireless docking station 100 through the Bluetooth connection with the USB wireless docking station 100, and then transmitted to the corresponding external USB device 200 through the USB interface. Based on this, the USB wireless docking station 100 provides additional interfaces and function expansions, so as to enable the external Bluetooth device to control multiple external USB devices 200 without occupying the high-speed interface of the external Bluetooth device.

[0047] It should be noted that the USB wireless docking station 100 and the external Bluetooth device perform data transmission through Bluetooth communication, and the rate of Bluetooth communication is usually low and cannot meet the high-rate communication requirements of the external USB device 200. Therefore, the external USB device 200 connected to the USB wireless docking station 100 here is a device that needs to meet low-rate communication.

[0048] The following Figure 2 communication system will be described in detail.

[0049] The external Bluetooth device includes a first electronic device 301. In one embodiment, the first electronic device 301 is a host device that runs Windows or Linux and Unix operating systems or their derivative systems in the form of a desktop computer and a laptop computer.

[0050] The first electronic device 301 has a first Bluetooth module 3011, so that the first electronic device 301 has Bluetooth transceiver capabilities and can be connected to the Bluetooth module 102 in the USB wireless docking station 100, thereby establishing a Bluetooth connection between the first electronic device 301 and the USB wireless docking station 100.

[0051] In addition, the first electronic device 301 also has a first application program 3012, and the first application program 3012 will be described in detail below.

[0052] The first application program 3012 is the driver software for the first electronic device 301. When the first electronic device 301 runs the first application program 3012, the first application program 3012 creates a virtual USB hub directly connected to the first electronic device 301 on the first electronic device 301. This virtual USB hub emulates the USB hub 101 on the USB wireless docking station 100, thus emulating the USB hub 101 on the USB wireless docking station 100 as a virtual USB hub directly connected to the first electronic device 301. Then, the first application program 3012 creates a corresponding virtual USB device on the first electronic device 301 for the external USB device 200 connected to the USB hub 101 on the USB wireless docking station 100, thus virtualizing the external USB device 200 on the USB wireless docking station 100 as a virtual USB device directly connected to the first electronic device 301.

[0053] It can be understood that in this embodiment, the external USB device 200 is directly connected to the USB interface of the USB hub 101 in the USB wireless docking station 100, rather than directly connected to the first electronic device 301. By running the first application program 3012, the first electronic device 301 can obtain a virtual USB hub and a virtual USB interface, and further simulate that the external USB device 200 is directly connected to the first electronic device 301 through the virtual USB interface of the virtual USB hub on the first electronic device 301. Through this simulation, the effect equivalent to the external USB device 200 being directly connected to the first electronic device 301 can be achieved, thereby realizing the USB communication ability between the first electronic device 301 and the external USB device 200 connected to the USB wireless docking station 100.

[0054] It should be noted that the number of virtual USB interfaces virtualized by the first application program 3012 is the same as the number of USB interfaces on the USB wireless docking station 100, and the functions of the virtual USB interfaces also correspond one by one to the functions of the USB interfaces on the USB wireless docking station 100.

[0055] During the running of the first application program 3012, a channel for controlling the external USB device 200 can be provided for the first electronic device 301, so that the third-party control software running on the first electronic device 301 can control the external USB device 200 through the first application program 3012.

[0056] Reference Figure 2As shown in the data flow, the first application 3012 mainly functions as a data forwarder. When the first electronic device 301 communicates with an external USB device 200 connected to the USB wireless docking station 100 (for example, sending control instructions), first, the control instructions issued by the device mounted on the virtual USB interface are received by the virtual USB interface and then transmitted to the virtual USB hub. After receiving these control instructions, the first application 3012 running on the first electronic device 301 transmits these data or commands to the USB wireless docking station 100 via Bluetooth, and finally transmits them to the actual external USB device 200 to execute the control instructions. Similarly, the data generated by the external USB device 200 is transmitted to the USB wireless docking station 100 through its connected USB interface. The USB wireless docking station 100 transmits these data to the first electronic device 301 via Bluetooth. The first application 3012 then sends the received data to the virtual USB hub, and then the virtual USB hub sends the data to the corresponding virtual USB device.

[0057] It can be seen that the first electronic device 301 exchanges data with the external USB device 200 on the USB wireless docking station 100 via Bluetooth through the communication between the virtual USB hub and the virtual USB device, so that the first electronic device 301 can remotely control and access the external USB device 200 connected to the USB wireless docking station 100.

[0058] In one embodiment, the first electronic device 301 further has a second application 3013. In actual applications, the second application 3013 is software with a graphical interface running on the first electronic device 301 for directly controlling the USB wireless docking station 100. Among them, the second application 3013 is a third-party application installed by the user for controlling the microprocessor of the USB wireless docking station 100.

[0059] Reference Figure 2 As shown in the data flow, the second application 3013 is connected to the first Bluetooth module 3011, and the second application 3013 can send commands to the USB wireless docking station 100 through the first Bluetooth module 3011. Reference Figure 3As shown in the control flow, the commands issued by the second application can be any customized operations, such as timed switching to cut off power to the USB external device 200 at a scheduled time, setting a name, reading power information, linking to customized operations made by other applications running on the first electronic device 301 for personalized configuration, etc. In addition, these customized operations can be further extended to the microprocessor 103 in the USB wireless docking station 100 to modify and configure the microprocessor 103. After receiving a command from the second application 3013, the USB wireless docking station 100 will perform corresponding operations according to the received command, so that the second application 3013 can perform customized operations on the USB wireless docking station 100 via Bluetooth, further realizing diversified customized functions.

[0060] Among them, the customized operation of the second application 3013 on the microprocessor 103 can be: controlling the microprocessor 103 to record the periodic control instructions forwarded by the first application 3012 and storing them.

[0061] In practical applications, the microprocessor 103 has the ability to expand external storage units, and the microprocessor 103 can use the external storage unit to store the periodic control instructions forwarded by the first application 3012. Specifically, the second application 3013 can monitor the data forwarded by the first application 3012 and determine whether there are periodic control instructions. If it is detected that the first application 3012 forwards periodic control instructions, it will control the microprocessor to store the periodic control instructions. In the case where no new communication data completely different from the previous ones appears, when the second application 3013 monitors that the first application 3012 needs to forward periodic control instructions next time, the second application 3013 tells the first application 3012 not to forward the periodic control instructions, and tells the microprocessor 103 to read the periodic control instructions from the external storage unit and execute them. Based on this, compared with directly transmitting a large number of complex control instructions issued by the second application 3012 to the microprocessor 103, it can reduce the occupancy of the Bluetooth bandwidth and realize the execution of periodic control instructions while using the minimum bandwidth.

[0062] It should be noted that during the process of using the second application 3013 to perform customized operations on the USB wireless docking station 100, the second application 3013 can perform customized operations on the first application 3012, the virtual USB hub, and the virtual USB interface, and the corresponding customized operations will be synchronously fed back to the USB wireless docking station 100, so that the real USB hub 101 and USB interface in the USB wireless docking station 100 perform synchronous customized operations.

[0063] In one embodiment, the external Bluetooth device further includes a second electronic device 302. Here, the second electronic device 302 includes a mobile phone and a tablet computer. The second electronic device 302 is a host device in the form of a mobile phone, a tablet computer, or a handheld game console that runs the Windows, Linux, or Unix operating system or its derivative systems.

[0064] The second electronic device 302 also has a second Bluetooth module 3021. Thus, the second electronic device 302 has Bluetooth transceiver capabilities and can be connected to the Bluetooth module 102 in the USB wireless docking station 100, thereby establishing a Bluetooth connection between the second electronic device 302 and the USB wireless docking station 100.

[0065] In addition, the second electronic device 302 also has a third application 3022. In practical applications, the third application 3022 is software with a graphical interface that is adapted to the second electronic device 302 for controlling the USB wireless docking station 100. The third application 3022 is connected to the second Bluetooth module 3021. The third application 3022 can communicate with the external USB device 200 connected to the USB wireless docking station 100 through the second Bluetooth module 3021. Specifically, referring to Figure 2 the data flow in the shown communication system and Figure 3 the schematic diagram of the control flow of the shown communication system, the third application 3022 uses the second Bluetooth module 3021 to send commands to the USB wireless docking station 100 through Bluetooth communication. These commands can be commands for controlling the external USB device 200, such as power supply control, timed operation, etc. After receiving the commands from the third application 3022, the USB wireless docking station 100 hands them over to the microprocessor 103 to perform corresponding operations according to the received commands, such as controlling the power supply of the USB interface. Thus, the third application 3022 can control the microprocessor 103 of the USB wireless docking station 100 through Bluetooth, realizing the control of the external USB device 200 connected to the USB interface of the USB wireless docking station 100. That is, the transmission path of the commands issued by the third application 3022 is "Bluetooth communication - microprocessor 103".

[0066] It should be noted that the microprocessor 103 has the ability to expand the external storage unit, and the microprocessor 103 can be connected to an external storage unit (such as a flash read-only memory Flash rom). Among them, the microprocessor 103 can communicate with the external storage unit through corresponding instructions and interfaces, and write some personalized configuration information and control information that needs to be sent repeatedly and regularly in the third application program 3022 into the external storage unit, so that the personalized configuration information and the control information sent repeatedly and regularly can be permanently stored in the external storage unit. When the third application program 3022 needs to convey these control information that needs to be sent repeatedly and regularly to the microprocessor 103, it can directly send operation instructions to the microprocessor 103 regularly. After receiving the operation instructions, the microprocessor 103 will run the corresponding preset program stored in the external storage unit. Among them, the preset program contains an instruction set for executing these control information or personalized configuration, so as to achieve the same effect that the third application program 3022 directly sends control information to the microprocessor 103 to execute the control information. In this processing method, the occupancy of the Bluetooth communication bandwidth by periodic repetitive information can be reduced, and problems such as delay and information loss caused by transmitting multiple repetitive instructions for multiple external USB devices 102 through Bluetooth can be avoided.

[0067] In the above communication system, the USB wireless docking station has Bluetooth transceiver capabilities, power supply control, data storage, and data forwarding capabilities. At the same time, it also has multiple USB interfaces to support the access of multiple external USB devices. The first electronic device has a first Bluetooth module, a first application program, and a second application program. The first Bluetooth module enables the first electronic device to have Bluetooth transceiver capabilities, so that the USB wireless docking station and the first electronic device can establish a Bluetooth connection. The first application program can enable the first electronic device to control the external USB devices on each USB interface of the USB wireless docking station through Bluetooth. The second application program can realize the personalized customization of the USB wireless docking station. The second electronic device also has a second Bluetooth module and a third application program. The second electronic device has Bluetooth transceiver capabilities, so that the USB wireless docking station and the second electronic device can establish a Bluetooth connection. The third application program can control the microprocessor of the USB wireless docking station to realize operations such as power supply control and timed work on the external USB devices connected to the USB interface of the USB wireless docking station. Among them, the USB wireless docking station is built using existing hardware chips and can be operated and managed in cooperation with the software running on the first electronic device and the second electronic device. Based on this, a USB wireless docking station with low rate and low power consumption, which can provide charging and control multiple external USB devices by an external Bluetooth device, can be provided in the communication system for multiple devices without high-speed communication requirements.
