In response to the above problems, the inventors found in the research that when the remote control is connected to various types of mobile terminals through its USB interface, the main reason for encountering various compatibility problems is that almost all of the current marketplaces incorporate the remote control into the remote control. The module used to communicate with the mobile terminal (such as the image transmission module of the drone) is directly connected to the mobile terminal through the USB interface, but the USB protocol does not have an absolute standard, and there are large differences between various remote control types or brands. And each mobile terminal, especially the mobile terminal of the Android system, focuses on the USB connection of mainstream USB devices, and it is difficult to take into account various other types of USB devices. In addition, the USB connection methods used by mobile terminals of different system types are not the same, and there is often a problem of losing sight of each other.

In practical applications, it can be an electronic device that is external to a certain smart terminal (such as a drone, smart car, or unmanned ship that is usually in a moving state) (that is, it exists independently of the smart terminal) ); Or, it can also be a functional component built into a smart terminal (such as a smart home, smart home appliance, etc.) (that is, it is integrated with the smart terminal); as long as it can communicate with the corresponding smart terminal's The control unit communicates and can communicate with the mobile terminal through a USB interface, which is not specifically limited in the embodiment of the present invention.

The embodiments of the present invention will be further described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an application environment of a communication method between a remote controller and a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 1, the application environment includes: a smart terminal 10, a remote controller 20, a first mobile terminal 30, and a second mobile terminal 40.

The smart terminal 10 may be any type of electronic device, such as an unmanned aerial vehicle, an unmanned ship, a smart car, a smart home, a smart home appliance, a robot, or the like. The smart terminal 10 may communicate with the remote controller 20 through its internal communication module 11 (for example, an image transmission module of a drone), and transmit the collected data to the remote controller 20, and / or receive A control signal sent by the remote controller 20.

The remote controller 20 may be any electronic device capable of controlling the smart terminal 10, and a control unit 21 (which may specifically be an MCU, a video transmission module, etc.) and a USB interface 22 connected to the control unit 21 may be provided therein. . The control unit 21 can communicate with the communication module 11 of the smart terminal 10, and the USB interface 22 is used to connect the control unit 21 to an external mobile terminal (for example, the first mobile terminal 30). Or the second mobile terminal 40), so that the external mobile terminal can obtain the data collected by the smart terminal 10 through the control unit 21, and / or send a control instruction to the communication module 11 of the smart terminal 10.

Particularly, in order to be able to establish a communication connection between the control unit 21 and a mobile terminal in different USB connection modes, in one embodiment, the remote controller 20 further includes a selection circuit 23, a first connection circuit 24, and A second connection circuit 25, and the control unit 21 connects the first connection circuit 24 and the second connection circuit 25 through the selection circuit 23, and further connects the first connection circuit 24 or the second connection circuit through the selection circuit 23. 25 is connected to the USB interface 22. Therefore, in this embodiment, by controlling the selection circuit 23, the control unit 21 may be connected to the USB interface 22 through the first connection circuit 24 to form a "first connection mode", or the The control unit 21 may also be connected to the USB interface 22 through the second connection circuit 25 to form a “second connection mode”. The first connection circuit 24 and the second connection circuit 25 may be designed according to the characteristics of mobile terminals of different system types (the mainstream Android system and IOS system will be described in detail in this specification later).

The first mobile terminal 30 and the second mobile terminal 40 may be any type of mobile electronic device, such as a smart phone, a tablet computer, etc., and the user may interact with one or more users through any suitable type. Devices (such as keyboards, touch screens, audio capture devices, etc.) interact with them to enter instructions or control them to perform one or more operations. In addition, the first mobile terminal 30 and the second mobile terminal 40 may run any type of system, such as an Android system, an IOS system, a Windows system, a Linux system, and the like. For an APP that interacts with the remote controller 20, a user can interact with the remote controller 20 or the smart terminal 10 based on the APP.

In practical applications, when the remote control 20 detects that a mobile terminal is connected to its USB interface 22, it may first determine the system type of the mobile terminal, and then select a USB connection mode (or, correspondingly, corresponding to the system type) USB connection circuit) establishes a communication connection with the mobile terminal.

For example, assuming that the system type of the first mobile terminal 30 is an Android system, and the system type of the second mobile terminal 40 is an IOS system, and it is set that the USB connection mode corresponding to the Android system is “the first A connection mode "; the USB connection mode corresponding to the IOS system is a" second connection mode ". Then, when the first mobile terminal 30 is connected to the USB interface 22, the system type of the first mobile terminal 30 can be determined by the control unit 21 in the remote control 20 as the Android system, and then the USB connection mode corresponding to the Android system can be selected. (Ie, the first connection mode) establishing a communication connection between the control unit 21 and the first mobile terminal 30 (specifically, the control unit 21 sends a first control instruction to the selection circuit 23 so that the selection circuit 23 communicates with the control unit 21 and the first connection circuit 24, and at the same time, the connection between the control unit 21 and the second connection circuit 25 is disconnected). Similarly, when the second mobile terminal 40 is connected to the USB interface 22, the system type of the second mobile terminal 40 can also be determined by the control unit 21 in the remote control 20 as an IOS system, and then the USB corresponding to the IOS system can be selected. The connection mode (that is, the second connection mode) establishes a communication connection between the control unit 21 and the second mobile terminal 40 (specifically, the control unit 21 sends a second control instruction to the selection circuit 23 so that the selection circuit 23 communicates with the The control unit 21 and the second connection circuit 25, meanwhile, disconnect the connection between the control unit 21 and the first connection circuit 24).

It should be noted that the communication method and related device of the remote controller and the mobile terminal provided by the embodiment of the present invention can be further extended to other suitable implementation environments, and is not limited to the implementation environment shown in FIG. 1. Although only one smart terminal 10, one remote control 20, and two mobile terminals (first mobile terminal 30 and second mobile terminal 40) are shown in FIG. 1, those skilled in the art can understand that in practical applications In the process, the application environment may further include more or fewer smart terminals 10 and / or mobile terminals. And, it should be understood that, in this embodiment, only two USB connection modes are used as an example for description. In other embodiments, in order to be able to form more USB connection modes, the selection circuit 23 and the A third connection circuit, a fourth connection circuit, a fifth connection circuit, and the like may also be provided between the USB interfaces 22.

FIG. 2 is a schematic flowchart of a communication method between a remote controller and a mobile terminal according to an embodiment of the present invention. The method can be executed by any type of remote controller, and the remote controller is provided with a USB interface for connecting the mobile terminal.

Specifically, referring to FIG. 2, the method may include, but is not limited to, the following steps:

Step 110: When it is detected that the mobile terminal is connected to the USB interface of the remote controller, determine the system type of the mobile terminal.

In this embodiment, the "mobile terminal" may be any type of removable electronic equipment, such as a mobile phone, a tablet computer, etc .; the "system type" is the type of the operating system of the mobile terminal, which may include but Not limited to: Android system, IOS system, Windows system, Linux system, etc.

In practical applications, there is usually an enumeration process (or USB debugging process) when two USB devices (such as a remote control and a mobile terminal) establish a connection, so that two connected USB devices pass the obtained Give information to understand what kind of device the other party is, how to communicate, etc. Therefore, when the remote control detects that an electronic device (which may be a mobile terminal or a non-mobile terminal such as a computer or server) is connected to its USB interface, it may first obtain an enumeration of the electronic device through the USB interface. Information, and extract the product ID (PID) of the electronic device from the obtained enumeration information, and then determine whether the electronic device belongs to a mobile terminal based on the product identification PID, and if so, it indicates that there is a mobile terminal currently Connect its USB interface, at this time, you can further determine the system type of the electronic device; if not, it means that the electronic device currently connected to the USB interface is another type of electronic device. At this time, based on the properties of the USB interface / Function to respond accordingly. For example, if the USB interface is only used to connect to a mobile terminal, it may not respond to the connected electronic device, or remind the user of the connected electronic device by issuing a prompt tone and presenting a prompt subtitle. The type is incorrect, which is not specifically limited in the embodiment of the present invention.

In addition, since the mobile terminal is marked with a Vendor ID (VID) corresponding to its system type in its USB device descriptor, for example, the VID of all mobile terminals in the IOS system is an Apple logo (eg, 0x05ac), The manufacturer's logo for all Android-based mobile terminals is the Google logo (for example, 0x18D1). Therefore, the specific implementation of "determining the system type of the mobile terminal" may be: further obtaining a USB device descriptor of the mobile terminal based on the obtained enumeration information, and then extracting the mobile from the obtained USB device descriptor The VID of the system of the terminal, and then the system type of the mobile terminal can be determined based on the VID. For example, if the acquired VID = 0x05ac, the system type of the mobile terminal can be determined to be an IOS system; if the acquired VID = 0x18D1, It can be determined that the system type of the mobile terminal is an Android system.

Step 120: Select a USB connection mode corresponding to the system type to establish a communication connection with the mobile terminal.

In this embodiment, the "USB connection mode" is the USB connection mode between the remote control and the mobile terminal. In practical applications, in order to improve the compatibility of the remote control with various system types of mobile terminals during USB connection, the remote control may internally set different USB connection methods corresponding to different system types of mobile terminals.

Generally, the operating systems of mobile terminals on the market are mostly Android systems or IOS systems. Therefore, in this embodiment, the remote control is based on the characteristics of the mobile terminal of the Android system and the mobile terminal of the IOS system. The USB connection mode is described as an example in detail.

Among them, the mobile terminals of the Android system mostly focus on the mainstream USB protocol, and it is difficult to take into account other types of USB protocols, and the compatibility of mainstream USB hubs (ie, USB HUB) is generally good. Therefore, in this embodiment, a “HUB connection mode” can be set for the mobile terminal of the Android system, and the mobile terminal of the Android system is connected by a USB HUB transfer method. For example, in the application environment shown in FIG. 1, one of the connection circuits (for example, the first connection circuit 24) can be set as a USB HUB circuit.

In addition, since the mobile terminal of the IOS system performs USB connection authentication, the connected USB device is subject to certification review. If the mobile terminal of the IOS system is also connected through the USB HUB transfer method, when the IOS system moves, When the terminal accesses the USB interface of the remote control, in the remote control, in addition to the control unit itself providing its enumeration information in accordance with the IOS protocol requirements, USB HUB will also provide its enumeration information, which will cause interference to the enumeration process. , So that it cannot pass the IOS certification review, and thus cannot establish a USB communication connection. Based on this, in this implementation, a "direct connection mode" can be set for the mobile terminal of the IOS system, and the control unit of the remote controller is directly connected to the USB interface. For example, in the application environment shown in FIG. 1, another connection circuit (for example, the second connection circuit 25) is set to be directly connected, that is, the control unit 21 is directly connected to the USB interface 22 through the selection circuit 23.

In this way, two different USB connection modes can be formed in the remote control: "HUB connection mode" and "direct connection mode". In practical applications, the remote control may select a corresponding USB connection mode based on the determined system type to establish a communication connection with the mobile terminal. For example, when it is determined that the system type of the mobile terminal connected to the USB interface is Android system, the remote control may select a HUB connection mode to establish a communication connection with the mobile terminal (specifically, establish a remote control (control unit) through the USB HUB and the USB interface). A communication connection with the mobile terminal); when it is determined that the system type of the mobile terminal connected to the USB interface is an IOS system, the remote control may select a direct connection mode to establish a communication connection with the mobile terminal (specifically, directly via USB The interface establishes a communication connection between a remote controller (control unit) and the mobile terminal).

Further, in order to make the remote controller meet the USB connection requirements of the Android system and the IOS system as much as possible and improve the USB connection efficiency, in some embodiments, a default state of the remote controller when the USB interface is powered on can also be preset. The default state includes the default USB connection mode of the remote control and the USB master / slave mode of the remote control. Among them, in order to prevent the USB HUB from interfering with the authentication review process of the IOS system when the mobile terminal of the IOS system is connected to the USB interface, the default USB connection mode of the remote control can be preset to the above-mentioned "direct connection mode". In addition, since the mobile terminal of the Android system is always a USB access device (that is, always in a USB slave mode), it can be preset that the remote controller is in a USB host mode when the USB interface is powered on.

Based on this, when it is determined that the system type of the mobile terminal connected to the USB interface is Android system, the control unit of the remote controller notifies the selection circuit to switch to the HUB connection mode, and at the same time, keeps the remote controller in the USB host mode and the mobile terminal in the USB slave When the system type of the mobile terminal connected to the USB interface is determined to be an IOS system, the control unit of the remote controller notifies the selection circuit to keep the direct connection mode unchanged. At the same time, in response to the native transmission protocol of the IOS, the The remote control switches from USB host mode to USB slave mode.

Furthermore, in order to enable the USB connection to be repeated multiple times, in some other embodiments, when it is detected that the mobile terminal is unplugged from the USB interface, the remote controller is restored to the above-mentioned default state (that is, the default USB connection). The mode is direct connection mode, and the remote control is in USB host mode).

Through the above technical solution, the embodiment of the present invention has the beneficial effect that the method for communicating between the remote control and the mobile terminal provided by the embodiment of the present invention first determines the system of the mobile terminal when it is detected that the mobile terminal accesses the remote control's USB interface. Type, and then select a USB connection mode corresponding to the system type to establish a communication connection with the mobile terminal, which can provide different USB connection modes for mobile terminals of different system types, adaptively dock various mobile terminals, and improve remote control based on Compatibility when USB is connected to various mobile terminals.
